Description

The present disclosure relates to a bonded component including a metal material, a bonded component manufacturing method, and a bonded component manufacturing apparatus.

2. Description of the Related Art Planetary carriers of planetary gear mechanisms used in drive system components of automobiles, such as transmissions and differentials, are generally formed by joining a plurality of metal members. For example, Patent Document 1 below describes a first member having a first end plate and a boss, a second end plate, and a plurality of members (three members arranged at a constant pitch in the circumferential direction) erected on one surface of the second end plate. ), and the distal end of each bridge includes a second member joined to the first end plate by electron beam welding.

Japanese Patent Application Publication No. 2007-268575 Patent No. 5124232 specification

Incidentally, the metal molten during welding hardens over time, but the metal may contract slightly during hardening, and the force generated due to this contraction may act to pull the joint. When a metal member is deformed or misaligned due to such an action, finishing work may be required to finally adjust the dimensions of a component that requires high dimensional accuracy, such as a planetary carrier. Furthermore, when electron beam welding is used to join multiple bridges to a common member, as in Patent Document 1, multiple joints are joined in sequence, so all joints are It takes a relatively long time to complete the bonding. In such a case, when the metal at the joint that was initially joined hardens, the metal members are not yet fixed to each other, so the contraction force when the metal at that point hardens causes the metal to harden. A predetermined amount of deviation (deformation) occurs between the members. On the other hand, when the metals at the joints joined after the initial joining described above harden, some of the joining between the metal members has been completed and the metal members are fixed to each other. The amount of displacement between the metal members caused by the contraction force when the metal at the location hardens is smaller than the amount of displacement that occurs during initial joining. Such a difference in the amount of deviation causes unexpected positional deviation in the parts obtained after joining, and can be a factor in deteriorating the parallelism of each member in the parts after joining. Furthermore, beam welding generally requires the use of a vacuum chamber or the like to bring the welding location into a vacuum state.

On the other hand, Patent Document 2 discloses that when manufacturing a component formed by joining a first member having an axially extending portion formed at a position radially away from the center of rotation and a second member having a hole, , it is described that the tip of the axially extending portion is inserted into the hole and resistance welded. According to the above-mentioned patent document 2, there is no need to create a vacuum atmosphere around the welding as in the beam welding described above. However, since the insertion depth of the tip is set smaller than the depth of the hole, it is difficult to secure the bonding area necessary to obtain sufficient bonding strength. In addition, since only one of the contact portions that are brought into contact when joining the first member and the second member is an inclined surface, the joining area may be small and the joining strength may be insufficient. Furthermore, the hole formed in the second member needs to be formed in accordance with the size of the tip of the first member to be joined each time the size changes, which requires time and effort to manufacture.

<First embodiment>
First, the configuration of each part of the bonded component 1 according to the first embodiment will be described. The joining component 1 (see FIG. 3) according to this embodiment may be, for example, a rotating automobile component. More specifically, it can be used as a planetary carrier for a planetary gear mechanism used in a transmission or a differential device. The joined component 1 according to this embodiment is manufactured by joining the first member 10 and the second member 20.

FIG. 1 is a perspective view showing an example of a first member of a joining component according to a first embodiment of the present disclosure. Moreover, FIG. 2 shows an example of the first member of the joining component according to the first embodiment of the present disclosure, in which FIG. 2(A) is a plan view and FIG. 2(B) is a diagram. 2(A) is a cross-sectional view taken along the line AA shown in FIG. As shown in FIGS. 1 and 2, the first member 10 constituting the joint component 1 according to the present embodiment includes a flat first plate portion 11 and an edge of the first plate portion 11. A plurality of legs 12 are connected to each other.

The first plate-shaped part 11 is formed of a plate made of metal (for example, aluminum, aluminum alloy, steel, cast iron, stainless steel, etc.) and has a first central hole 13 formed through its center. I can do it. A plurality of (three in FIGS. 1 and 2) through holes 14 are formed around the first central hole 13 at predetermined angular intervals. The rotating shaft of the pinion gear that constitutes the mechanism can be supported. The center of the first central hole 13 can be the rotation center RA when the joining component 1 rotates.

The plurality of leg portions 12 are arranged at positions separated (separated) from the rotation center RA by a predetermined distance in a direction intersecting the rotation center RA. Specifically, from a plurality of locations (three locations in FIGS. 1 and 2) on the edge of the first plate-shaped portion 11, in a direction intersecting the rotation center RA of the joined component 1, for example, the first plate-shaped portion 11; a bent part 16 connected to the end of the extended part 15 and bent in a direction along the rotation center RA of the joint component 1; 16 and a hanging portion 17 extending a predetermined length in a direction along the rotation center RA of the joint component 1. By including such a configuration, the plurality of legs 12 can have a substantially L-shaped appearance. The plurality of leg portions 12 may be integrally formed with the first plate-like portion 11. Further, the plurality of leg portions 12 may be provided at predetermined angular intervals with respect to the rotation center RA of the joint component 1, for example. In this embodiment, the plurality of legs 12 includes three legs 12, but the number of legs 12 may be two, four or more. . Furthermore, as described above, the hanging portion 17 extends in the direction along the rotation center RA, but the direction along the rotation center RA here refers to the direction parallel to the extending direction of the rotation center RA. It may include not only a direction but also a direction inclined at a slight angle (for example, about 1 to 15 degrees) with respect to the extending direction of the rotation center RA.

The bend 16 may be bent such that its outer portion forms a substantially right angle corner. As a result, the upper surface of the bent portion 16 (corresponding to a pressed surface PS2 to be described later) may be a flat surface extending in a direction intersecting the rotation center RA. In addition, the end of the hanging portion 17 constituting the plurality of legs 12 opposite to the end connected to the bent portion 16 is the tip of the leg that joins with the hole 22 of the second member 20, which will be described later. 17A can be configured. Further, the end portion of the leg tip 17A may be a tip end surface 17D formed as a substantially flat surface, and the edge thereof may be chamfered to form a leg-side tapered portion 17C. Further, the hanging portion 17 may have a curved shape such that the cross section when cut along the direction intersecting the rotation center has an arc shape centered on the rotation center RA. Note that the cross section may be rectangular instead of the above-mentioned arc shape.

FIG. 3 shows an example of the second member of the joining component according to the first embodiment of the present disclosure, in which FIG. 3(A) is a plan view, and FIG. 3(B) is a plan view of FIG. FIG. 3 is a cross-sectional view taken along line BB shown in FIG. The second member 20 constituting the joint component 1 according to the present embodiment includes a flat second plate-shaped portion 21, as shown in FIG.

The second plate-shaped portion 21 can be formed of a flat metal plate that is approximately circular in plan view. The metal constituting the second plate-like portion 21 may be the same as that of the first plate-like portion 11 or may be different. A second central hole 23 may be formed in the center of the second plate-like part 21, penetrating from the front surface 21F to the back surface 21R of the second plate-like part 21. A plurality of (three in FIG. 3) through holes 24 may be formed around the second central hole 23 at predetermined angular intervals, and each through hole 24 has a first plate-shaped Similarly to the through hole 14 provided in the portion 11, it is possible to support, for example, a rotating shaft of a pinion gear that constitutes a planetary gear mechanism. The center of the second central hole 23 can be the rotation center RA when the joining component 1 rotates. That is, the centers of the first central hole 13 and the second central hole 23 can be located on the same line when the first member 10 and the second member 20 are joined.

A plurality of holes 22 are provided in the second plate-shaped portion 21 at positions separated by a predetermined distance from the rotation center RA in a direction intersecting the rotation center RA, more specifically in a radial direction (radial direction). As shown in FIG. 3, the hole 22 according to the present embodiment is a through hole having a predetermined depth D1 that penetrates from the front surface 21F to the back surface 21R of the second plate-shaped portion 21, and The hole can be formed into a substantially arc shape. The length of this hole 22 from the surface closer to the rotation center RA to the surface farther from the rotation center RA in the direction intersecting the rotation center RA, more specifically, in the extending direction of the second plate-shaped portion 21. (Hereinafter, this length is also referred to as the "width of the hole") W21 is the distance from the surface of the leg tip 17A on the side closer to the rotation center RA in the direction intersecting the rotation center RA to the side farther from the rotation center RA. (hereinafter, this length is also referred to as "width of the tip of the leg") W11 (see FIG. 2) (for example, in a numerical range of millimeter order or micro order). By adjusting the width W11 of the leg tip and the width W21 of the hole in advance to such dimensions, the leg tip 17A can be press-fitted into the hole 22 when joining both members, and at least Two surfaces, the surface closer to the rotation center RA and the surface farther from the rotation center RA, are solid-phase joined.

Further, as shown in FIG. 3, the hole 22 is formed in a circular arc shape in plan view having a predetermined extension angle W22, for example, at a position a predetermined distance apart in the radial direction from the rotation center RA of the second plate-like portion 21. It is possible to adopt a configuration in which three pieces are provided according to the positions of the leg portions 12. Here, the extension angle W22 of the three holes 22 is either slightly smaller than the extension angle W12 of each hanging part 17 of the three legs 12, or greater than the extension angle W12 of each hanging part 17. It is adjusted as follows. If the extension angle W22 of the hole 22 is made slightly smaller than the extension angle W12 of the hanging part 17, when the leg tip 17A is inserted into the hole 22, the four inner peripheral surfaces of the hole 22 and the leg tip It becomes possible to perform solid phase welding with the four outer circumferential surfaces of 17A. This has the advantage that a wider joint area can be ensured compared to the case where the extension angle W22 of the hole 22 is set to be equal to or larger than the extension angle W12 of the hanging portion 17. Note that, if the leg portion 12 is formed to have the above-mentioned rectangular cross section, the hole portion 22 may also be formed to have a rectangular shape in plan view in accordance with the shape of the leg portion 12.

Furthermore, instead of providing a plurality of holes 22 in accordance with the number of legs 12, a ring-shaped hole centered around the rotation center RA may be used. When the hole 22 is configured as a ring-shaped hole in this way, the degree of freedom in positioning when manufacturing the first member 10 and the second member 20 is increased, and the manufacturing process of the second member 20 is also improved. At times, there is no need to consider the extension angle W12 of the hanging portion 17. Thereby, the yield during manufacturing of the first member 10 and the second member 20 can be further improved. Furthermore, a plurality of first members that differ only in the extension angle W12 of the hanging portion 17 can be joined to the second member 20 whose hole portion 22 is ring-shaped, and common parts can be realized.

Among the openings of the holes 22 located on the surface 21F side of the second plate-like part 21, at least the edge on the side closer to the rotation center RA in the extending direction of the second plate-like part 21 and the side far from the rotation center RA The edge of the hole may be chamfered to form a hole-side tapered portion 22C. The inclination angle of the hole-side taper portion 22C may be substantially the same as the inclination angle of the leg-side taper portion 17C. In this way, in addition to the leg-side tapered portion 17C provided at the edge of the leg tip 17A near the rotation center RA and the edge far from the rotation center RA, the rotation center RA of the opening of the hole 22 By providing the hole-side tapered portion 22C on the edge closer to the center of rotation and the edge farther from the rotation center RA, when joining the first member 10 and the second member 20, both tapered portions 17C, 22C are provided. constitutes the bonding surface and can form a large bonding area. Thereby, the bonding strength of the bonded portion of the bonded component 1 can be increased. In this embodiment, a case is illustrated in which both the leg side taper part 17C and the hole side taper part 22C are provided, but only one of them may be provided, or the taper part may not be provided. You can.

The joining component 1 according to the present embodiment is formed by solid phase joining of a first member 10 and a second member 20 having the above-described configuration. Specifically, each of the leg tips 17A of the plurality of legs 12 is press-fitted into one or more holes 22 and energized, so that at least a portion of the side surface of the leg tips 17A and the hole 22 are press-fitted into one or more holes 22. At least a portion of the inner circumferential surface of the inner peripheral surface may be solid phase bonded. Here, "solid-phase bonding" refers to a method of bonding by applying pressure or heating while applying pressure or heat in a solid phase (solid state) without melting the bonding material. However, even if local melting occurs during bonding in the first member 10 and second member 20 as bonding materials due to their shapes, most of the bonding surfaces will remain in a solid state. If the bonding is performed, it corresponds to "solid phase bonding" in the present disclosure. This makes it possible to simultaneously join a plurality of joint surfaces between the first member 10 and the second member 20, and prevents deformation and positional misalignment caused by different joining timings of the plurality of joint surfaces. It can be suppressed. By suppressing the above-mentioned deformation, there is almost no need to separately perform finishing processing for dimensional adjustment, and the manufacturing process can be simplified. In addition, since the joining timing of the joint parts is the same, the contraction force when the metal at the joint parts hardens is generated at substantially the same timing at each joint part, and the parallelism of each member in the parts after joining is improved. It can be expected that the deterioration of

However, the joined parts joined by the present manufacturing apparatus 2 are not limited to the above-mentioned joined parts 1.

Note that the first member 10 shown in FIG. 4 is shown spaced upward from the second member 20 so that its structure can be easily understood. As shown in FIG. 4, the bonded component manufacturing apparatus 2 according to the present embodiment has a first electrode 30 in contact with the first member 10 of the bonded component 1 and a second electrode 30 in contact with the second member 20 of the bonded component 1. A pressurizing device capable of relatively moving a first member 10 and a second member 20 by relatively moving a second electrode 40 in contact with each other, and a first electrode 30 and a second electrode 40. 50, and an energizing device 60 that supplies current between the first electrode 30 and the second electrode 40.

The first electrode 30 can be made of a conductive material that is electrically connected to the first member 10 by having its lower surface at least partially contact the upper surface of the first member 10 . In this embodiment, the upper surface of the first electrode 30 is fixed to the pressure device 50, and can move in the direction indicated by the arrow M1 (vertical direction) following the operation of the pressure device 50. can. In this regard, the first electrode 30 is preferably formed such that its lower surface contacts at least a portion of the bent portion 16 of each of the plurality of legs 12. Since the first electrode 30 contacts the plurality of legs 12, the pressure from the pressure device 50 can be applied to each leg 12 without waste. Therefore, the first electrode 30 does not need to be in contact with the first plate portion 11.

Here, the first electrode 30 shown in FIG. The lower surface PS1 that contacts the member 10 (hereinafter also referred to as the "pressing surface") is configured as a substantially horizontal surface, and a portion of the pressing surface PS1 contacts a portion of the bent portion 16. It is formed. The reason why such a contact structure is adopted is mainly to prevent deformation of the leg portion 12 or poor connection that may occur when the pressurizing force from the pressurizing device 50 is generated in a direction different from the extending direction of the hanging portion 17. This is to suppress the However, the shape of the pressing surface PS1 of the first electrode 30 is not limited to this. Specifically, the pressing surface PS1 of the first electrode 30 is a surface located on the opposite side of the leg tips 17A in the direction along the rotation center RA of the plurality of legs 12 (hereinafter, this surface is referred to as " It may have any shape as long as it contacts at least a portion of PS2 (referred to as "pressed surface"). With such a shape, the leg tip 17A can be pressed in a direction along the extending direction of the hanging portion 17, in other words, in a direction along the extending direction of the rotation center RA. The pressed surface PS2 can also be said to be a surface located directly above the leg tip 17A. In the first member 10 shown in FIG. 4, the pressed surface PS2 is made up of the outer surface of the bent portion 16 and a part of the extended portion 15, and the pressed surface PS1 is configured to intersect with the rotation center RA. In this example, the length in the direction of pressing is set to be longer than the pressed surface PS2, and a portion of the pressing surface PS1 is arranged to press a portion of the pressed surface PS2.

FIG. 5 is an enlarged view of a main part showing a modification of the first electrode of the manufacturing apparatus shown in FIG. FIG. 5 is an enlarged view of a portion of the first electrode in FIG. 4 (specifically, a portion corresponding to the left side portion in FIG. 4). As shown in FIG. 5(A), the first electrode 30A according to a modification of the present embodiment has a pressing surface PS1 set to a size matching the pressed surface PS2. According to this first electrode 30A, since the pressing surface PS1 can be made small, the first electrode 30B itself can be made small.

Further, although the first member 10 described above has a corner formed on the outside of the bent portion 16, the bent portion has a curved shape (hereinafter, this bent portion is referred to as “bent portion 16A”). It may be. The bent portion 16A may be configured with a curved surface 16A1 whose outer side is curved in an arc shape. In this regard, the first electrode 30B according to another modification of the present embodiment is designed to increase the contact area between the pressed surface PS2 and the pressed surface PS1, as shown in FIG. 5(B). A contact protrusion 31 having a shape that follows the pressed surface PS2, particularly the curved surface 16A1 of the bent portion 16A, is provided. By employing such a contact protrusion 31, when the first member 10 is pressed with the first electrode 30, the contact protrusion 31 and the curved surface 16A1 come into contact with each other, so that the pressing surface PS1 and the pressed surface PS2 are connected to each other. The contact area of the pressurizing device 50 can be increased, and the pressurizing force from the pressurizing device 50 can be applied more reliably in the direction along the extending direction of the hanging portion 17.

The second electrode 40 is made of a conductive material, on which the second member 20 is placed, and which is electrically connected to the second member 20 by contacting the back surface 21R of the second plate-shaped portion 21. It can be composed of In order to immovably support the second member 20, a holding device (not shown) such as a suction device or a plurality of grippers movable along the top surface of the second electrode 40 is provided on the top surface of the second electrode 40. It is preferable if it is provided.

The pressurizing device 50 presses the first electrode 30 and the second electrode 40 in a direction in which they approach each other so as to move the first electrode 30 and the second electrode 40 relative to each other, so that the first member 10 and the second member 20 are connected to the plurality of legs. The device may be a device capable of moving the leg end 17A of the section 12 in the direction of inserting it into the hole 22. In this embodiment, a device that can move the first electrode 30 in the direction indicated by arrow M1 is employed. Thereby, the first electrode 30 can be brought into contact with the first member 10, and the first member 10 can be moved in a direction approaching the second member 20. The detailed configuration of the pressurizing device 50 is not shown in the drawings, but it is typically a piston-cylinder mechanism using fluid (water, oil, air, etc.) or a direct-acting device using an electric motor such as a ball screw or linear motor. mechanism can be adopted. Note that although the pressurizing device 50 according to the present embodiment is exemplified as one that presses the first electrode 30 side, it is not limited to such a configuration as long as the operating direction is the same. It is also possible to adopt a configuration in which the two electrodes 40 side or both of the two electrodes 30 and 40 can be pressed.

The current supply device 60 may be a power supply circuit for supplying current to the joint surface of the first member 10 and the second member 20 via the first electrode 30 and the second electrode 40. The energizing device 60 typically includes a charging circuit connected to a commercial AC power source 61, a capacitor charged by the charging circuit, a transformer, etc., and the first member 10 and the second member 20 are connected. It is possible to adopt a device that supplies a pulsed current to the bonding surface. Here, the pulsed current is typically a single pulsed current. The pulsed current may have a current peak value of, for example, tens of thousands to hundreds of thousands of amperes, and a pulse width of, for example, 10 milliseconds to 100 milliseconds. Regarding the specific current peak value and pulse width, the material and shape of the first member 10 and the second member 20, or the target temperature during energization (specifically, the softening temperature of the first and second members) It can be selected as appropriate depending on the melting temperature, etc.). This pulsed current makes it possible to heat the bonding surfaces and ensure the bonding of the bonding surfaces.

The joining component manufacturing apparatus 2 according to the present embodiment has the above-described configuration, thereby providing a manufacturing apparatus capable of simultaneously joining a plurality of joining surfaces of a first member and a second member. I can do it. The bonded parts manufactured using this manufacturing apparatus 2 are suppressed from deformation and positional deviation caused by bonding, and from deterioration in parallelism between the first and second members.

<Method for manufacturing bonded parts>
Next, a method for manufacturing a bonded component according to an embodiment of the present disclosure will be described. In this embodiment, the above-mentioned manufacturing apparatus 2 is used as an apparatus that executes the method for manufacturing the bonded component, and the bonded component 1 described above is used as the bonded component as the object to be bonded. However, it should be clearly understood that the manufacturing method of the present disclosure is not limited to implementation by the above-described manufacturing apparatus 2, and that it is also possible to manufacture bonded components different from the bonded component 1 described above. Note that the explanation of the effects and the like shown below also serves as an explanation of the effects of the manufacturing apparatus 2 and the bonded component 1 according to the present embodiment.

FIG. 6 is a flowchart illustrating an example of a method for manufacturing a bonded component according to the first embodiment of the present disclosure. Further, FIG. 7 is an explanatory diagram of the operation when joining the first member and the second member of the joining component according to the first embodiment of the present disclosure, and FIG. FIG. 7(B) shows the state immediately before the start of operation of the energizing device, and FIG. 7(C) shows the state when the bonding is completed. Note that, in FIG. 7, a portion corresponding to a part of the joint portion shown in FIG. 4 (specifically, the left side portion in FIG. 4) is shown in an enlarged manner. Moreover, this FIG. 7 is shown in an end view so that the joining process can be easily recognized.

In the method for manufacturing a bonded component according to this embodiment, as shown in FIGS. 6 and 7, first, the first member 10 and the second member 20 are provided in the manufacturing apparatus 2 (step S1). Specifically, after placing and fixing the second member 20 on the upper surface of the second electrode 40, the first member 10 is placed on the upper surface side of the fixed second member 20, with the tip of the leg thereof The first and second members 10 and 20 are placed in the manufacturing apparatus 2 by placing the first member 17A aligned with the hole 22 of the second member 20 (see FIG. 7(A)). . At this time, the leg-side tapered portion 17C provided at the leg tip 17A of the plurality of legs 12 and the hole-side tapered portion 22C provided at the end of the surface side 21F of the plurality of holes 22 are connected. When brought into contact with each other, alignment between the first member 10 and the second member 20 described above can be guided.

Next, the pressurizing device 50 is operated to start moving the first electrode 30 downward (step S2). When a predetermined period of time has elapsed after the first electrode 30 started moving, the pressing surface PS1 of the first electrode 30 comes into contact with the pressed surface PS2 of the plurality of legs 12 (see FIG. 7(B)). .

When the pressing surface PS1 of the first electrode 30 and the pressed surface PS2 of the first member 10 come into contact (Yes in step S3), the pressing device 50 presses at least the first member 10 and the second member 20. One movement is started. Then, while the operation of the pressurizing device 50 continues, that is, in parallel with the movement by the pressurizing device 50, the energizing device 60 is operated to start supplying current between the first and second electrodes 30 and 40. (Step S4). As a result, a pressing force is applied and a current is supplied to the joint surface between the first member 10 and the second member 20, that is, the contact portion between the leg tip 17A and the hole 22. When a current is supplied between the contact portion between the leg tip 17A and the hole 22, more specifically between the leg side taper portion 17C and the hole side taper portion 22C, both of the abutted taper portions 17C, 22C and The surrounding area is heated by Joule heat, and the temperature is raised to the softening temperature of the metal constituting at least one of the first member 10 and the second member 20. Then, due to the pressurizing force applied from the pressurizing device 50, the joint surface portion whose temperature has been raised to the softening temperature is press-fitted (plastic flow), and the joint surfaces are solid-phase joined, forming the joint JA1. .

After the supply of current between the first and second electrodes 30 and 40 is started, when the application of pressure force by the pressure device 50 is continued, the leg tip 17A is inserted into the hole 22 ( press-fitting) progresses. When the insertion depth of the leg tip 17A reaches the specified insertion depth L1 (Yes in step S5), the leg tip 17A and hole 22 are moved by the pressure device 50 and energized by the energization device 60. The step of joining is completed (step S6). Here, the depth D1 of the hole is equal to or shorter than the specified insertion depth L1, in other words, the depth D1 of the hole is set to be equal to or shorter than the specified insertion depth L1. This is something that should be especially noted. In this way, when the specified insertion depth L1 is greater than or equal to the depth D1 of the hole (that is, L1≧D1), as shown in FIG. is formed over the entire length of the inner peripheral surface of the hole 22 in the depth direction. As a result, the area of the joint JA1 is secured to be larger than that in the case where the insertion depth of the leg tip is smaller than the depth of the hole, so it is possible to provide a joint component 1 with high joint strength at the joint part. This is a manufacturing method that can be used. Note that in this embodiment, as described above, a method for manufacturing a bonded component in which the bonding surfaces of the first member 10 and the second member 20 are bonded by solid phase bonding is described, but instead of this, The joint surfaces of the first member 10 and the second member 20 can also be welded using a joining method that involves melting of the joint surfaces, such as resistance welding.

As described above, in the method for manufacturing a joined component according to the present embodiment, a plurality of (three in the above-mentioned joined component 1) joint parts are simultaneously connected, and the joint surface is the surface closer to the rotation center RA. Joining can be performed at at least two locations on the side far from the rotation center RA. This makes it possible to suppress deformation and misalignment that occur when joining the members, as well as deterioration in parallelism between the members. In addition, in the bonded parts manufactured by this manufacturing method, since the bonded part can be formed over the entire length of the hole 22 in the depth direction, a wide bonded area can be secured, and the bonded part can be maintained even when the bonded parts are used. Less likely to be damaged due to lack of strength.

In the above-described joined component 1 according to the present embodiment, only the side surface portion of the leg tip 17A is joined to the hole 22 as an example. However, the present disclosure is not limited only to the structures described above. Specifically, in addition to the side surface portion of the leg tip 17A, the lower surface portion of the leg tip 17A may be joined to the hole 22. Therefore, a joint component 1A according to a modified example of the present embodiment and a method for manufacturing the same will be described below. Note that the manufacturing device 2 described above can be used as a device for manufacturing this bonded component 1A.

FIG. 8 is an explanatory diagram of an operation when joining a first member and a second member of a joining component according to a modification of the first embodiment of the present disclosure, and FIG. FIG. 8(B) shows the state immediately before the pressurizing device starts operating, FIG. 8(B) shows the state immediately before the energizing device starts operating, and FIG. 8(C) shows the state when the bonding is completed. Note that, like FIG. 7, FIG. 8 is an enlarged end view of a part of the joint portion. As shown in FIG. 8, the joint component 1A according to this modification has a leg tip 17B of the first member 10A having a projection 18 that projects from the tip surface 17D in the direction along the rotation center RA. It has the same configuration as the joining component 1 described above, except that the hole 22A of the second member 20A is formed as a bottomed hole having a bottom wall 25 and a predetermined depth D2. It's fine. Therefore, the parts of the joined part 1A having the same configuration as the joined part 1 are given the same reference numerals and the explanation thereof will be omitted.

The protrusion 18 is formed to protrude from the tip surface 17D in the direction along the rotation center RA, and comes into contact with the bottom wall 25 when the first and second members are joined, and the end part thereof plastically flows to form the joint. It forms JA3. The protrusion 18 shown in FIG. 8 is exemplified as being formed by extending the leg-side tapered portion 17C. Further, the bottom wall 25 can be formed of a wall having a substantially horizontal surface and having a predetermined thickness. The thickness of the bottom wall 25 is such that when the first member 10A is placed on the top surface of the second member 20A, the tips of the protrusions 18 are in contact with the top surface of the bottom wall 25, or are in a position extremely close to the top surface of the bottom wall 25. It is adjusted as follows. By performing this adjustment, the protrusion 18 and the bottom wall 25 can be reliably joined.

A manufacturing method for manufacturing the bonded component 1A having the above-described configuration will be described below. Note that the process for manufacturing the bonded component 1A is similar to the process for manufacturing the bonded component 1, so the following description will be made with reference to FIGS. 6 and 8.

First, a first member 10A and a second member 20A are provided in the manufacturing apparatus 2 (step S1). Specifically, after placing and fixing the second member 20A on the upper surface of the second electrode 40, the first member 10A is placed on the upper surface side of the fixed second member 20A with its leg end The first and second members 10A and 20A are placed in the manufacturing apparatus 2 by placing the first member 17B aligned with the hole 22A of the second member 20A (see FIG. 8(A)). . Next, the pressurizing device 50 is operated to start moving the first electrode 30 downward (step S2). When a predetermined period of time has elapsed after the first electrode 30 started moving, the pressing surface PS1 of the first electrode 30 comes into contact with the pressed surface PS2 of the plurality of legs 12 (see FIG. 8(B)). .

When the pressing surface PS1 of the first electrode 30 and the pressed surface PS2 of the first member 10A contact each other (Yes in step S3), the pressing device 50 presses at least the first member 10A and the second member 20A. One movement is started. Then, while the operation of the pressurizing device 50 continues, that is, in parallel with the movement by the pressurizing device 50, the current supply device 60 is operated to supply current between the first and second electrodes 30 and 40. (Step S4). As a result, a pressing force is applied and a current is supplied to the joint surface between the first member 10A and the second member 20A, that is, the contact portion between the leg tip 17B and the hole 22A. After the supply of current between the first and second electrodes 30 and 40 is started, when the application of pressure force by the pressure device 50 is continued, the leg tip 17B is inserted into the hole 22A ( press-fitting) progresses. When the leg tip 17B is inserted into the hole 22A, the side surface of the leg tip 17B first comes into contact with the inner wall surface of the hole 22A and plastically flows, thereby starting to form the first joint JA2. , the tip of the protrusion 18 comes into contact with the surface of the bottom wall 25 and plastically flows, thereby starting to generate the second joint JA3. When the insertion depth of the leg tip 17B reaches the specified insertion depth L2 (Yes in step S5), the leg tip 17B and hole 22A are moved by the pressure device 50 and energized by the energization device 60. The step of joining is completed (step S6).

Also in this modification, the depth D2 of the hole 22A is set to be less than or equal to the specified insertion depth L2, in other words, the depth D2 of the hole is set to be the same as or shorter than the specified insertion depth L2. It is important to pay special attention to the fact that When the specified insertion depth L2 is equal to or greater than the depth D2 of the hole 22A (that is, L2≧D2), the tip of the protrusion 18 can be brought into contact with the surface of the bottom wall 25 during bonding, and as shown in FIG. ), the second joint JA3 can be formed separately from the first joint JA2. As a result, the area of the first joint JA2 of the joint component 1A of this modified example is small compared to the area of the joint JA1 described above, but it is wide by forming the second joint JA3 separately. The bonding area can be secured.

FIG. 9 is an enlarged view of main parts showing a joining component according to another modification of the first embodiment of the present disclosure. Note that this FIG. 9 shows the same state as FIG. 8(A). The first member 10B of the joint component according to this modification has a protrusion 18A that protrudes from the distal end surface 17D of the leg distal end 17E in the direction along the rotation center RA, as in the first modification shown in FIG. have. However, unlike the protrusion 18 shown in the first modification, this protrusion 18A is different from the surface near the rotation center RA in the direction intersecting the rotation center RA at its base end to the surface far from the rotation center RA. The length up to the tip end face 17D is set smaller than the length at a similar position on the distal end surface 17D.

By setting the base end of the protrusion 18A as described above, dimensioning becomes easy. Note that the shape of the protrusion is not limited to the two shapes described above. Specifically, a plurality of them may be arranged parallel to each other on the distal end surface 17D, or a plurality of them may be arranged in spots on the distal end surface 17D.

Furthermore, similarly to the hole 22 described above, instead of providing a plurality of holes corresponding to the number of legs 12, the hole 22A may be configured with a ring-shaped hole centered on the rotation center RA. can. When the hole portion 22A is configured with a ring-shaped hole, the degree of freedom in positioning when manufacturing the first members 10A, 10B and the second member 20A increases, and it also increases the degree of freedom in positioning when manufacturing the second member 20A. There is no need to consider the extension angle W12 of the hanging portion 17. Thereby, the yield during manufacturing of the first members 10A, 10B and the second member 20A can be further improved. In addition, since a plurality of first members that differ only in the extension angle W12 of the hanging portion 17 can be joined to the second member 20A whose hole portion 22A is ring-shaped, for example, it is possible to use common parts. .

<Second embodiment>
In the first embodiment described above, the depth of the holes 22, 22A is less than or equal to the insertion depth of the leg tips 17A, 17B, but the present disclosure also applies to such dimensions. Not limited. Based on this, a second embodiment of the present disclosure will be described below. Note that the joint component 1B according to the second embodiment can be the same as the joint component 1 according to the first embodiment described above, except for the shape of the second member 20B. Specifically, the shape etc. of the first member may be the same as the first member 10 of the joining component 1 described above. Therefore, among the various configurations of the joint component 1B according to the second embodiment, only the parts that are different from the joint component 1 according to the first embodiment will be explained below, and The same reference numerals are given to the parts common to the joined part 1, and the description thereof will be omitted as the above description will be referred to.

FIG. 10 shows an example of a second member of a joining component according to a second embodiment of the present disclosure, in which FIG. 10(A) is a plan view and FIG. 10(B) is a plan view of FIG. FIG. 3 is a cross-sectional view taken along line CC shown in A). As shown in FIG. 10, the second member 20B of the joint component 1B (see FIG. 11) according to the present embodiment is located at a predetermined distance in the radial direction from the rotation center RA of the second plate-shaped portion 21. A ring hole 22B having an annular shape centered on the rotation center RA is provided. As shown in FIG. 10(B), the ring hole 22B is a bottomed hole in which a bottom wall 25A is provided at a position extending a predetermined depth D3 from the surface 21F of the second plate-shaped portion 21. be able to. The length of the ring hole 22B from the surface closer to the rotation center RA to the surface farther from the rotation center RA in the direction intersecting the rotation center RA, more specifically, in the extending direction of the second plate-shaped portion 21. (Hereinafter, this length will also be referred to as the "width of the ring hole.") W31 is smaller than the width W11 of the leg tip 17A. By adjusting the width W31 of the ring hole and the width W11 of the leg tip 17A to these dimensions, by pressurizing and inserting the leg tip 17A into the ring hole 22B, the surface closer to the rotation center RA can be It becomes possible to solid-phase weld the two surfaces of the surface farthest from the center of rotation RA.

The joined component 1B according to the present embodiment is formed by solid phase joining of the first member 10 and the second member 20B. Specifically, by press-fitting the leg tips 17A of the plurality of legs 12 into the ring hole 22B, at least part of the side surface of the leg tips 17A and at least one of the outer wall surface and inner wall surface of the ring hole 22B are pressed. The parts may be solid-phase joined. This makes it possible to simultaneously join a plurality of joint surfaces between the first member 10 and the second member 20B, and suppresses deformation caused by different joining timings of the plurality of joint surfaces. . By suppressing the above-described deformation, there is no need to separately perform finishing processing for dimensional adjustment, and the manufacturing process can be simplified. In addition, since the joining timing of the joint parts is the same, the contraction force when the metal at the joint parts hardens is generated at substantially the same timing at each joint part, and the parallelism of each member in the parts after joining is improved. It can be expected that the deterioration of

Further, since the joint component 1B according to the present embodiment employs the ring hole 22B described above, the second member 20B can be connected to the second member 20B without considering the extension angle W12 or the number of the legs 12 of the first member 10. can be manufactured, which facilitates its manufacture. Further, since the first member 10 to be joined to the second member 20B is not restricted in any way with respect to the extension angle W12 and the number of legs 12, for example, a plurality of types of first members having different numbers of legs may be used. The members 10 can be joined, and parts can be shared. Furthermore, since there is a high degree of freedom in alignment in the circumferential direction when joining the first member 10 and the second member 20B, the yield when manufacturing the first member 10 and the second member 20B is improved. .

Next, a method for manufacturing the bonded component 1B according to the present embodiment will be briefly described below. Note that the above-described manufacturing apparatus 2 can be used as the apparatus for manufacturing the bonded component 1B. Furthermore, since the process for manufacturing the bonded component 1B is similar to that of the manufacturing method for the bonded component 1, the following description will be made mainly with reference to FIGS. 6 and 11.

FIG. 11 is an explanatory diagram of the operation when joining the first member and the second member of the joining component according to the second embodiment of the present disclosure, and FIG. 11(A) is an operation explanatory diagram of the operation of the pressurizing device. FIG. 11(B) shows the state immediately before the start of operation of the energizing device, and FIG. 11(C) shows the state immediately before the joining is completed. Note that, like FIGS. 7 and 8, FIG. 11 is an enlarged end view of a part of the joint portion. When manufacturing the bonded component 1B according to this embodiment, first, the first member 10 and the second member 20B are provided in the manufacturing apparatus 2 (step S1). Specifically, after placing and fixing the second member 20B on the upper surface of the second electrode 40, the first member 10 is placed on the upper surface side of the fixed second member 20B with its leg end The first and second members 10 and 20B are placed in the manufacturing apparatus 2 by placing the ring hole 22B of the second member 20A with the ring hole 22B aligned with the ring hole 22B of the second member 20A (see FIG. 11(A)). . Next, the pressurizing device 50 is operated to start moving the first electrode 30 downward (step S2). When a predetermined period of time has elapsed after the first electrode 30 started moving, the pressing surface PS1 of the first electrode 30 comes into contact with the pressed surface PS2 of the plurality of legs 12 (see FIG. 11(B)). .

When the pressing surface PS1 of the first electrode 30 and the pressed surface PS2 of the first member 10 come into contact (Yes in step S3), the pressing device 50 presses at least the first member 10A and the second member 20A. One movement is started. Then, while the operation of the pressurizing device 50 continues, that is, in parallel with the movement by the pressurizing device 50, the current supply device 60 is operated to supply current between the first and second electrodes 30 and 40. (Step S4). As a result, a pressing force is applied and a current is supplied to the joint surface between the first member 10 and the second member 20B, that is, the contact portion between the leg tip 17A and the ring hole 22B. After the supply of current between the first and second electrodes 30 and 40 is started, when the application of pressure force by the pressure device 50 is continued, the leg tip 17A is inserted into the ring hole 22B ( press-fitting) progresses. When the leg tip 17A is inserted into the ring hole 22B, the side portion of the leg tip 17A comes into contact with the outer and inner wall surfaces of the ring hole 22B and plastically flows, thereby starting to form a joint JA4. When the insertion depth of the leg tip 17A reaches the prescribed insertion depth L3 (Yes in step S5), the leg tip 17A and ring hole 22B are moved by the pressure device 50 and energized by the energization device 60. The step of joining is completed (step S6).

In this embodiment, as described above, the depth D3 of the ring hole 22B does not need to be equal to or less than the insertion depth L3 of the leg tip 17A. In particular, since the ring hole 22B according to the present embodiment is exemplified as a hole with a bottom, the depth D3 of the ring hole 22B is preferably greater than or equal to the insertion depth L3 of the leg tip 17A.

Also in the method for manufacturing a joined component according to the present embodiment, as described above, a plurality of joint parts are simultaneously connected, and at least two of the joint surfaces thereof are a surface near the rotation center RA and a surface far from the rotation center RA.
