JP 2002-79401 A

Since the combined machining machine tool described in Patent Document 1 is based on a lathe, the combined tool can swing with respect to the tool rest, but can move greatly to any position around the workpiece. I don't have that much stroke.
For this reason, when turning, the tool post controller drives and controls the tool drive motor to turn the composite tool around its axis, index the desired insert to a predetermined position, and position the workpiece. Turning with this insert.
As described above, in the combined machining machine tool based on a lathe, it is necessary to perform indexing control for indexing the insert by turning the composite tool, and the control of the entire machine tool is complicated.
Also, in order to turn the composite tool so that it can be indexed, the composite tool at the time of turning must be electrically positioned and held, so it was difficult to increase the rigidity of the composite tool at the time of turning. .

  The present invention has been made to solve such a problem, and it is not necessary to perform indexing control (C-axis control) for turning a spindle on which a compound turning tool is mounted to index a chip, and turning. An object of the present invention is to provide a multi-tasking machine and a turning method that can increase the rigidity of a multi-turning tool at the time.

In order to achieve the above-described object, in the multi-tasking machine according to the present invention, the spindle head that rotatably supports the spindle is movable in three orthogonal directions relative to the workpiece, and the table or the spindle stock is A multi-tasking machine capable of turning a work piece disposed opposite to a main shaft and gripped and rotated by the table or the head stock with a multi-turning tool mounted on the main shaft and having a plurality of chips, The compound turning tool is moved in parallel by a head moving operation and is positioned at an arbitrary position around the workpiece, whereby the plurality of chips are appropriately used for turning.
The composite turning tool is preferably positioned and fixed to the end of the spindle head by a fixing means comprising a key and a keyway.
As a preferred embodiment, in the multi-tasking machine, the axis of the spindle is oriented in a direction substantially perpendicular to the floor surface, and the table that can be positioned upward by gripping the workpiece is positioned higher than the height of the spindle head. This is a 5-axis control vertical machining center which is arranged below and is capable of swinging and at least rotating by being driven by a table driving device.
In the turning method according to the present invention, the workpiece is turned by appropriately using the chips of the compound turning tool by using the compound machine.

  Since the multi-tasking machine and the turning method of the present invention are configured as described above, it is not necessary to perform indexing control (C-axis control) for turning the main shaft on which the multi-turning tool is mounted to index the chips. The rigidity of the compound turning tool during turning can be increased.

In the multi-tasking machine of the following embodiment, the multi-turn tool is moved in parallel by moving the spindle head and positioned at an arbitrary position around the workpiece, and a plurality of inserts of the multi-turn tool are appropriately used. There is no need to perform indexing control (C-axis control) for indexing the tip by a turning operation, and the object of increasing the rigidity of the composite turning tool during turning is realized.
The multi-tasking machine in the present embodiment is a multi-tasking machine based on a machining center (basic structure). In this multi-tasking machine, the spindle head that rotatably supports the spindle can be moved greatly in the three orthogonal directions relative to the workpiece, and the table is arranged to face the spindle.
This combined processing machine can perform various processes such as a turning process using a turning tool and a cutting process using a rotating tool. At the time of turning, for example, a workpiece that is gripped and rotated by a table is turned with a compound turning tool mounted on a spindle and having a plurality of chips.
The multi-task machine of the following embodiment shows a case of a 5-axis control vertical machining center having a so-called “cradle type” table that can be swung. The multi-tasking machine of the present invention may be a machine tool in which the spindle head is relatively movable in three orthogonal directions with respect to the workpiece and the table is disposed to face the spindle. The machining center may be a vertical or horizontal turning center.
The multi-tasking machine according to the present invention may be a machine tool that uses a lathe as a base (basic structure) and can at least turn a workpiece. In this multi-tasking machine based on a lathe, the spindle head that rotatably supports the main spindle on which the multi-turning tool is mounted can move greatly in three orthogonal directions relative to the work piece. A spindle head to be gripped is disposed to face the spindle of the spindle head.

Hereinafter, an embodiment according to the present invention will be described with reference to FIGS.
1 to 6 are views showing an embodiment of the present invention, FIG. 1 is a perspective view of a combined machining machine, FIG. 2 is a partially enlarged front view showing the periphery of a combined turning tool, and FIG. 3 is a plan view of FIG. 4 is a side view taken along the line IV-IV in FIG. 2, FIG. 5A is a perspective view showing the relationship between the composite turning tool and the workpiece, and FIG. 5B is an upside-down view of FIG. It is a perspective view which shows the state seen from the direction. FIG. 6 is a cross-sectional plan view taken along the line VI-VI in FIG. 2 and shows the operation during turning.

As shown in FIGS. 1 to 6, the multi-task machine 1 is a machine tool based on a vertical machining center and capable of turning at least a workpiece 2.
The multi-tasking machine 1 is controlled by a control device 20 including an NC (numerical control) device and a programmable logic controller (PLC). Note that the control device 20 may be one in which a PLC unit is built in the NC device.
The axis CL of the main shaft 3 of the multi-task machine 1 is substantially perpendicular to the floor surface 4, but is inclined at a predetermined angle with respect to the vertical direction (also in this case, “almost to the floor surface”). It may be facing “vertical direction”.
A spindle head 5 that rotatably supports the spindle 3 is movable in three orthogonal directions (X axis direction, Y axis direction, Z axis direction) relative to the workpiece 2 placed on the pallet 7. is there. A table 6 capable of gripping the workpiece 2 via the pallet 7 is disposed below the main shaft 3.
The multi-tasking machine 1 of this embodiment is a 5-axis control vertical machining center having a “cradle type” table 6 that can swing around the B axis.

In the multi-task machine 1, the direction parallel to the axis CL of the main shaft 3 is defined as the Z axis (the vertical axis in FIG. 1), and the respective axis directions orthogonal to the orthogonal coordinate system are defined as the X axis and the Y axis. . For convenience of explanation, the −Y axis direction, + Y axis direction, + X axis direction, and −X axis direction are defined as the front and rear, the right side, and the left side of the multi-task machine 1, respectively.
In the present embodiment, the spindle head 5 moves in the three orthogonal axes, but the spindle head 5 moves in the two orthogonal axes (for example, the X-axis direction and the Y-axis direction), and the lower table moves. It may be a multi-tasking machine that moves in one axial direction (for example, the Z-axis direction).

The multi-tasking machine 1 can turn a workpiece 2 that is gripped and rotated by a table 6 with a multi-turning tool 10 that is mounted on a spindle 3 and has a plurality of (here, four) chips 9a to 9d. The four chips 9a to 9d are regularly attached to the tool holder 50 of the composite turning tool 10 at a predetermined angle (here, 90 degrees) in the circumferential direction around the central axis CL2 in plan view. .
The composite turning tool 10 is mounted on the main spindle 3 in a non-rotating state so as to increase the rigidity during turning.
Then, if the spindle head 5 is largely moved in the two axial directions, the X-axis direction and the Y-axis direction, the compound turning tool 10 moves in parallel in these two axial directions. As a result, the composite turning tool 10 is positioned at an arbitrary position around the workpiece 2 (for example, arbitrary positions S1, S2, S3, S4), and a plurality of (four) chips 9a to 9d are appropriately disposed. Turning is performed properly. Arbitrary positions S1, S2, S3, S4 are not limited to one point, but are a certain range of movement when the compound turning tool 10 moves during the turning operation.
In order to index the chips 9a to 9d of the compound turning tool 10, conventionally, the compound turning tool 10 is indexed by a turning operation of the compound turning tool (a turning operation around the central axis of the tool). The chips 9a to 9d are indexed by making a large parallel movement in the two axial directions, the axial direction and the Y-axis direction.
As a result, the multi-tasking machine 1 does not need to perform indexing control (C-axis control) in which the spindle 3 on which the multi-turning tool 10 is mounted is turned to index the chips 9a to 9d.

Since one composite turning tool 10 is provided with a plurality of (four) tips 9a to 9d, each tip 9a to 9d is selectively used by one composite turning tool 10 (for example, a plurality of times). Alternatively, multiple types of turning can be performed.
In the present embodiment, the case where the composite turning tool 10 can translate the entire periphery of the workpiece 2 is shown. However, the composite turning tool 10 is not at the entire circumference of the workpiece 2 but at an arbitrary position around a part of the workpiece 2. It may be a case of parallel movement.
The workpiece 2 is held by the table 6 via the pallet 7. As a modification, a chuck may be provided on the table 6 without using the pallet 7, and the workpiece 2 may be detachably gripped by the chuck.

The multi-task machine 1 includes an automatic pallet changer (hereinafter referred to as APC) 21 as a pallet changer for changing the pallet 7. The APC 21 is arranged in the vicinity of the machining area 22 and is controlled by the control device 20. A pallet setup table 11 on which the pallet 7 can be placed is provided outside the processing region 22.
In the multi-task machine 1, the unprocessed workpiece 2 placed on the pallet 7 is supplied from the pallet setup table 11 to the table 6 by the APC 21. When processing such as turning by the composite turning tool 10 or cutting by the rotary tool 33 is completed, the pallet 7 on which the processed workpiece 2 is placed is returned from the table 6 to the pallet setup table 11 by the APC 21.

The APC 21 includes a pallet setup table 11 and a pallet exchange arm 40. The pallet exchanging arm 40 pivots in a substantially horizontal plane with the axis CL1 as a center, and ascends and descends in the direction of the axis CL1 as indicated by an arrow E. The axis CL1 of the turning center of the pallet exchanging arm 40 is directed in the vertical direction parallel to the Z-axis direction.
The pallet exchange arm 40 is provided with at least one (here, a pair) pallet gripping portion 41 capable of gripping and releasing the pallet 7. The pallet exchange arm 40 moves the pallet 7 between the table 6 and the pallet setup table 11 by performing a turning operation and an elevating operation, and also moves the pallet 7 with respect to the table 6 and the pallet setup table 11. Has a function to deliver.
The pallet exchanging arm 40 only performs a turning operation and an elevating operation and does not perform an operation of reciprocating linearly in the horizontal direction. Therefore, the pallet 7 can be replaced in a short time and the APC 21 can be simplified. A compact configuration can be achieved.
The pallet exchanging apparatus according to the present invention may be a case where the pallet exchanging arm 40 is turned and moved up and down by manual operation instead of the APC 21.

Next, the configuration of the multi-task machine 1 will be described.
The multi-task machine 1 has a bed 13 that constitutes the base 12 thereof. A saddle 14 is provided on the base 12 so as to be movable in the X-axis direction (left-right direction) while being guided by the X-axis guide rail 15.

The table 6 is provided with a clamp / unclamp mechanism 19 for clamping / unclamping the pallet 7. With the pallet 7 mounted on the table 6, the pallet 7 can be clamped to the table 6 by the clamp / unclamp mechanism 19. The table 6 is provided with a drive unit (not shown) for driving the clamp / unclamp mechanism 19 to clamp / unclamp the pallet 7.

The table driving device 30 includes a swinging drive device 31 for swinging the table 6 around the B axis, and an indexing device for indexing and rotating the pallet 7 around the A axis with respect to the table 6. And a driving device 32. The B axis is parallel to the Y axis direction, and the A axis is the rotation center of the table 6.
The swing drive device 31 is disposed in front of the multi-task machine 1, and supports the table 6 so as to be swingable. By driving the swing driving device 31, the table 6 and the indexing drive device 32 provided on the table 6 swing around the B axis and are indexed to a predetermined position.

At the time of turning, when the indexing drive device 32 is rotationally driven, the pallet 7 and the workpiece 2 supported by the table 6 rotate around the A axis. In this way, when the workpiece 2 is rotated around the A axis at a predetermined rotational speed while the workpiece 2 is placed on the pallet 7, the workpiece 2 is combined with the main spindle 3. It is turned by a turning tool such as the tool 10.
On the other hand, when the rotary tool 33 is mounted on the spindle 3 and cutting is performed with the rotary tool 33, the indexing drive device 32 is controlled, and the workpiece 2 on the pallet 7 is moved by the indexing drive device 32. Index to a predetermined position around the A axis. In this state, the workpiece 2 placed on the pallet 7 is cut by the rotary tool 33 of the main shaft 3.

The processing region 22 is covered with a splash guard (not shown) so that cutting fluid (coolant), chips, and the like are not scattered outside. The splash guard is provided with a shutter for exchanging a workpiece and a shutter for exchanging a tool, and each can be opened and closed. By opening and closing these shutters, the workpiece 2 and the tools 10 and 33 can be replaced.
The base body 12 is provided with an automatic tool changer (hereinafter referred to as ATC, not shown) capable of storing a plurality of tools and exchanging tools. The ATC has a function of indexing predetermined tools (or empty tool storage units) 10 and 33 to a tool change position and automatically changing the tools 10 and 33 with the spindle 3.
In the ATC, in addition to a turning tool (for example, the composite turning tool 10) for turning the workpiece 2, a rotating tool 33 for cutting is housed. In addition, you may provide the tool magazine for accommodating the some tools 10 and 33 separately from ATC.
The control device 20 has an operation panel 23. The operation panel 23 is provided with display means (display, CRT, etc.) and input means (keyboard, touch panel, etc.), so that the multi-tasking machine 1, APC 21, ATC, etc. can be operated.
In the vicinity of the bed 13, a coolant tank (not shown) for storing the cutting fluid supplied to the processing position is disposed.

In the multi-tasking machine 1 configured as described above, the spindle head 5 is movable relative to the workpiece 2 supported by the pallet 7 on the table 6 in the three orthogonal directions, and the table 6 is used for the table. It is driven by the drive device 30 to be able to swing, index and rotate.
Therefore, the multi-task machine 1 can process the workpiece 2 by 5-axis control of the X axis, the Y axis, the Z axis, the A axis, and the B axis, so that a turning tool (for example, Further, turning with the composite turning tool 10) and cutting with the rotary tool 33 are possible.
As a result, the types of workpieces that can be machined by the multi-tasking machine 1 are increased, and various types of machining can be performed on these workpieces, and the multi-tasking machine 1 can function as a multi-function machine. it can.

The composite turning tool 10 of the present embodiment has an assembly structure with the chips 9a to 9d, but may be a tool that is not an assembly structure. Moreover, although the case where four chips 9a to 9d are provided in one composite turning tool 10 is shown, the number of chips may be plural (preferably even), for example, two or six. , 8 may be used.
The composite turning tool 10 includes a tool holder 50 serving as a main body and a plurality of (here, four) bodies 51 that are detachably fixed to the tool holder 50. One chip is attached to the tip of each body 51. The chips 9a to 9d are fixed to the body 51 by brazing, welding, or the like, or fastened and fixed detachably by a fastening member such as a screw.
Around the tool holder 50, a plurality of (here, four) groove portions 51 extending in a direction parallel to the central axis CL2 are formed. The groove 51 opens to the outer periphery, and is evenly arranged around the tool holder 50 by 90 degrees apart.
Each body 51 is detachably fastened and fixed by a screw 52 while being engaged with the groove 51. As a result, the four chips 9a to 9d are evenly spaced apart by 90 degrees around the tool holder 50 in plan view with the central axis CL2 as the center.

The tool holder 50 is provided with a flange portion 53 and a shank 54 in the direction opposite to the tips 9a to 9d. The main body portion, the flange portion 53 and the shank 54 of the tool holder 50 are integrally formed as a whole, but may be formed separately.
A V-groove 55 and a large-diameter flange 56 are formed in the flange portion 53. A gripping portion of an ATC tool change arm is detachably engaged with the V groove portion 55 so that the composite turning tool 10 is changed.
The large-diameter flange 56 has an outer diameter larger than the outer diameter of the flange portion of the rotary tool 33, and the flange portion 53 including the large-diameter flange 56 includes one or a plurality of (here, a pair) keys. A groove 57 is formed. The pair of key grooves 57 are disposed in the opposite directions by 180 degrees across the central axis CL2 of the composite turning tool 10, and are formed facing the radial direction.

A key 58 that is detachably engaged with the key groove 57 is fixed at a predetermined position of an end portion (here, a lower end portion) 5 a of the spindle head 5 so as to face the radial direction of the spindle head 5. The key 58 engages with the key groove 57 of the large-diameter flange 56 only when the composite turning tool 10 is mounted on the main shaft 3. And the key 58 is arrange | positioned in the position away from the flange part of the rotary tool 33 so that it may not interfere with the rotational motion of the rotary tool 33, when the rotary tool 33 is mounted | worn with the main axis | shaft 3. FIG.
Thus, the compound turning tool 10 mounted on the spindle 3 is positioned and fixed to the end 5a of the spindle head 5 in a non-rotating state by the fixing means 59 including the key 58 and the key groove 57. Increases rigidity during turning.
As a modification, the fixing means 59 may have a configuration in which a key is fixed to the composite turning tool 10 and a key groove with which the key is engaged is formed in the end portion 5 a of the spindle head 5.
The shank 54 of the composite turning tool 10 is detachably mounted on a mounting portion 3b formed on the end 3a side of the main shaft 3, and is clamped / unclamped to the main shaft 3 by a clamp / unclamp mechanism.

Next, a method for turning the workpiece 2 by appropriately using the chips 9a to 9d of the composite turning tool 10 by using the composite machine 1 will be described.
In the combined processing machine 1 before turning, the pallet 7 is mounted on the table 6 by operating the APC 21, and the unprocessed workpiece 2 to be processed is fixed to the pallet 7. The pallet 7 is clamped to the table 6 by a clamp / unclamp mechanism 19.
Further, by driving the swing driving device 31 to swing the table 6, the pallet 7 faces upward, and the A axis of the workpiece 2 on the table 6 is parallel to the axis CL of the main shaft 3 (that is, , Parallel to the Z axis).
When performing oblique machining, the table 6 is positioned so that the A axis of the workpiece 2 on the table 6 is inclined with respect to the axis CL of the main shaft 3.

The compound turning tool 10 is mounted on the spindle 3 by an ATC tool change operation. The shank 54 of the composite turning tool 10 is mounted on the mounting portion 3b of the main shaft 3 and is clamped by a clamp / unclamp mechanism.
The large diameter flange 56 of the composite turning tool 10 is in close contact with the end 3 a of the main shaft 3. Further, since the key 58 fixed to the spindle head 5 is engaged with the key groove 57 of the large diameter flange 56, the compound turning tool 10 is positioned and fixed to the end portion 5 a of the spindle head 5 by the fixing means 59. Has been.
Conventionally, the turning tool is electrically positioned and held by electrical indexing control (C-axis control), and the workpiece is turned with this turning tool, whereas the composite turning tool 10 of the present invention is used. Is mechanically positioned and fixed to the end 5 a of the spindle head 5 by a fixing means 59. Therefore, the rigidity of the composite turning tool 10 at the time of turning can be made higher than before.

When the unmachined workpiece 2 on the pallet 7 fixed to the table 6 is turned, the indexing drive device 32 is driven to move the pallet 7 and the workpiece 2 on the table 6 to a predetermined rotational speed. Rotate with
In this state, if the spindle head 5 is moved in a biaxial direction perpendicular to the X-axis direction and the Z-axis direction (or a biaxial direction perpendicular to the Y-axis direction and the Z-axis direction), the composite mounted on the spindle 3 The workpiece 2 can be turned by the turning tool 10.
By moving the spindle head 5 in parallel, the compound turning tool 10 is translated and positioned at any position around the workpiece 2 (for example, any position S1, S2, S3 or S4). The four chips 9a, 9b, 9c, and 9d are properly used for turning.

Even if the compound turning tool 10 is translated to any position S1, S2, S3 or S4 around the workpiece 2, the compound turning tool 10 is not rotated on the end 5a of the spindle head 5 by the fixing means 59. The positioning remains fixed, and the coordinates of the center position O1 of the workpiece 2 do not change.
Therefore, for example, by determining the coordinates of the spindle 3 when the compound turning tool 10 is located at the position S1 with respect to the workpiece 2, it is determined that the tip 9a is currently selected, and the spindle head 5 movement operations are controlled.
Similarly, when the compound turning tool 10 is located at another position S2, it is determined that another tip 9b is selected, and the movement operation of the spindle head 5 is controlled. Further, when the chips 9c and 9d are used, the movement operation of the spindle head 5 is similarly controlled.

Since the multi-task machine 1 is a machine tool based on a machining center, the spindle head 5 can be moved in three orthogonal directions relative to the workpiece 2. Therefore, the complex turning tool 10 can be positioned at an arbitrary position S1, S2, S3 or S4 around the workpiece 2, and a plurality of (four) chips 9a to 9d can be used appropriately and turned. .
For example, when using the left tip 9 a of the composite turning tool 10, the composite turning tool 10 is positioned at the right position S 1 of the workpiece 2 and the tip 9 a is opposed to the workpiece 2.
In addition, the tip 9b on the front side of the composite turning tool 10 may be used in order for the left tip 9a to reach the tool life or change the type of turning. At this time, the spindle head 5 is moved in two directions orthogonal to the X-axis direction and the Y-axis direction, and the composite turning tool 10 is moved in parallel to be positioned at a position S 2 behind the workpiece 2. As a result, the front chip 9 b faces the workpiece 2.
Similarly, when the right tip 9c of the compound turning tool 10 is used, the spindle head 5 is moved in two orthogonal directions of the X axis direction and the Y axis direction, and the compound turning tool 10 is moved in parallel. Then, the workpiece is positioned to the left of the workpiece 2, and the right chip 9c is opposed to the workpiece 2.
When using the rear tip 9d of the composite turning tool 10, the spindle head 5 is moved in two orthogonal directions, the X-axis direction and the Y-axis direction, and the composite turning tool 10 is moved in parallel. 2, the rear chip 9 d is opposed to the workpiece 2.
Then, if the spindle head 5 is controlled to move in the biaxial direction perpendicular to the X-axis direction and the Z-axis direction (or the biaxial direction perpendicular to the Y-axis direction and the Z-axis direction), the chip 9a, 9b, 9c or 9d The object 2 can be turned.

On the other hand, when the unmachined workpiece 2 on the pallet 7 fixed to the table 6 is cut, the indexing drive device 32 is driven to index and position the workpiece 2 at a predetermined position.
Then, the rotary tool 33 mounted on the spindle 3 is rotated at a predetermined rotational speed, and the spindle head 5 is moved relative to the workpiece 2 fixed on the pallet 7 on the table 6 in the three orthogonal directions. However, the workpiece 2 is cut with the rotary tool 33.
When the workpiece 2 is turned with another type of turning tool or when other types of cutting are performed, the machining operation is performed after exchanging the tool between the spindle 3 and the ATC. Resume.

When the turning or cutting of one workpiece 2 is completed, the machined workpiece 2 and the next unmachined workpiece 2 are exchanged by the APC 21, and then the machining process is started again.
By repeating such a procedure, turning and cutting of the workpiece 2 are sequentially performed. Thus, turning, cutting and the like can be performed on the workpiece 2 sequentially and automatically.
By driving the oscillating drive device 31, the workpiece 2 can be indexed in a desired oblique direction in addition to the vertical direction and the horizontal direction, and various types of turning and cutting can be performed freely.

As described above, in the combined machining machine 1 and the turning method according to the present invention, the compound turning tool 10 is moved in parallel by the moving operation of the spindle head 5 to be positioned at arbitrary positions S1 to S4 around the workpiece 2. The chips 9a to 9d are properly used.
Therefore, without turning the spindle 3 and indexing control (C-axis control) for indexing the chips 9a to 9d, the spindle head 5 is moved in two directions, the X-axis direction and the Y-axis direction. By simply moving and positioning the tool 10, the plurality (four) of the chips 9a to 9d can be used properly, respectively, so that the control of the entire multi-task machine 1 is simplified.
Conventionally, there has been a case where the tool spindle is controlled by the C axis to index the tip of the turning tool. Compared to the conventional indexing speed, the composite turning tool 10 of the present embodiment is placed at arbitrary positions S1 to S4. It was found that the positioning speed was slightly faster.
Since the composite turning tool 10 is forcibly positioned and fixed to the spindle head end portion 5a by the fixing means 59, the rigidity of the composite turning tool 10 during turning can be increased. Therefore, stable and highly accurate turning can be performed, the turning time can be shortened, and turning can be performed even when the workpiece 2 is hard.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and additions are possible within the scope of the gist of the present invention.
In the drawings, the same reference numerals denote the same or corresponding parts.

  The complex machine of the present invention may be a complex machine that can be turned with a complex turning tool, and can be applied to a vertical machining center, a horizontal machining center, a turning center, and the like.
