Detailed Description
Hereinafter, preferred embodiments of the coating surface correction apparatus of the present application will be described with reference to the drawings. The same reference numerals are given to the same contents and corresponding parts, and detailed description thereof is omitted. In the following embodiments, the same reference numerals are used to omit redundant description.
Embodiment 1.
Fig. 1 shows a rotary compressor 1 including a crankshaft 50 as a workpiece of a coated surface correction device according to embodiment 1. The rotary compressor 1 is manufactured by disposing the crankshaft 50, the coated surface of which is corrected as described later, at the center portion. The operation of the rotary compressor 1 will be briefly described. The crankshaft 50 is rotationally driven by an electric mechanism 4, and the electric mechanism 4 has a rotor 2, and the rotor 2 is fixed to the crankshaft 50 and rotated by electromagnetic force of a stator 3. Thereby, the rotary pistons 6 fixed to the upper eccentric portion 53 and the lower eccentric portion 54 of the crankshaft 50, respectively, rotate along the inner peripheral surface of the cylinder block 5. A vane (not shown) that slides in contact with the outer peripheral surface of the rotary piston 6 divides a cylinder chamber in the cylinder block 5 into a suction chamber that sucks in the refrigerant and a compression chamber that compresses the refrigerant. The refrigerant is compressed by the compression mechanism 7, and the compression mechanism 7 is composed of a cylinder block 5, a rotary piston 6, and vanes. The rotary pistons are not limited to two, and may be rotary compressors having one or more rotary pistons 6.
Since the crankshaft 50 slides with a plurality of other members, a surface is coated (coated) with a lubricating paint or the like to improve slidability. A coating surface correction apparatus 100 for correcting the coating surface will be described.
Fig. 2 is a schematic configuration diagram of a coated surface correction device 100 according to embodiment 1. The coated surface correction device 100 includes: a rotation support device 20 that rotatably supports a crankshaft 50 as a workpiece; and a rotation driving device 30 for rotationally driving the crankshaft 50. Further, a lifting device 40 that can be driven in a direction perpendicular to the axis of the crankshaft 50 is provided, the lifting device 40 is fixed to the housing 10, and a coated surface correction tool unit 60 is mounted at the end of the lifting device, and the coated surface correction tool unit 60 is used for correcting the coated surface of the crankshaft 50.
The lifting device 40 is driven to press the coated surface correction tool unit 60 against the crankshaft 50, and the crankshaft 50 is rotated by the rotation driving device 30 to correct the coated surface of the crankshaft 50.
Fig. 3 is a perspective view of a crankshaft 50 as a work piece. The crankshaft 50 is composed of a main shaft portion 51, a sub shaft portion 52, a non-coated shaft portion 55, and an upper eccentric portion 53 and a lower eccentric portion 54 which are coaxially provided and provided on axes which are parallel to and different from the axis of the crankshaft 50. Since the main shaft portion 51, the auxiliary shaft portion 52, the upper eccentric portion 53, and the lower eccentric portion 54 are portions where sliding occurs with other members, coating for improving slidability is performed. If there are protrusions on these surfaces, the assembly accuracy is affected, or the sliding property is adversely affected, and therefore, correction processing for removing the protrusions is required.
Further, at both ends of the crankshaft 50, an upper center hole 56 and a lower center hole 58 for processing or for supplying oil are formed. Further, a driving groove 57 is formed on the outer shape side of the upper center hole 56. The crankshaft 50 is supported from both sides by engaging the upper center hole 56 with the rotary support device 20 and engaging the lower center hole 58 with the rotary drive device 30, and the drive groove 57 is attached to the drive unit of the rotary drive device 30 to rotate the crankshaft 50.
However, the shape of the workpiece is not limited to the above shape. For example, if the non-coated shaft portion 55 is held and rotated, the present invention can be applied to a workpiece having a shape not having the upper center hole 56 and the driving groove 57. In the case where the lower center hole 58 is not provided, the outer diameter portion of the sub-shaft portion 52 may be rotatably supported by a roller or the like.
Fig. 4 is a side view of the coated surface correction tool unit 60. The main shaft portion correction tool unit 61, the auxiliary shaft portion correction tool unit 62, the upper eccentric portion correction tool unit 63, and the lower eccentric portion correction tool unit 64 are integrally attached to the unit base 65. The main shaft portion correction tool unit 61 is used for machining the main shaft portion 51 as a coating portion, the auxiliary shaft portion correction tool unit 62 is used for machining the auxiliary shaft portion 52 as a coating portion, the upper eccentric portion correction tool unit 63 is used for machining the upper eccentric portion 53 as a coating portion, and the lower eccentric portion correction tool unit 64 is used for machining the lower eccentric portion 54 as a coating portion, and the basic configuration is the same. Therefore, the correction tool unit 63 for the upper eccentric portion will be described below as a representative example of the coating portion.
Fig. 5 is a front cross-sectional view A-A of fig. 4 of the upper eccentric portion correction tool unit 63. The upper eccentric portion correction tool unit 63 includes a guide rail 71. The guide rail 71 is attached to the unit base 65. The slider 72 is movably attached to a surface of the rail 71 opposite to a surface attached to the unit base 65 along the rail 71. A slide base 73 that moves integrally is attached to the slide 72. A guide pin 74 is attached to one end of the slide base 73, and a correction tool base 75 is attached to the other end of the guide pin 74 via a linear bushing 76. A compression spring 77 that engages with the slide base 73 and the correction tool base 75 is disposed around the guide pin, and the correction tool base 75 and the slide base 73 are biased at a constant interval, and when the interval becomes narrower than the constant interval, a spring reaction force is generated in the compression spring 77.
The drop preventing bolt 79 is fixed to the correction tool base 75, and the drop preventing bolt 79 penetrates the correction tool 80 for processing the coated surface, and is formed so that the correction tool 80 does not drop, whereby the correction tool 80 is suspended so as to be movable along the drop preventing bolt 79. The spherical washer 78 penetrates the drop preventing bolt 79 and is disposed between the correction tool 80 and the correction tool base 75.
The operation of the coated surface correction tool unit 60 configured as described above when correcting the coated surface of the crankshaft 50 will be described with reference to the correction tool unit 63 for the upper eccentric portion as a representative example.
When the upper eccentric portion correction tool unit 63 is lowered by the lifting device 40, the correction tool 80 contacts the upper eccentric portion 53 of the crankshaft 50.
Since the correction tool 80 is suspended by the drop preventing bolt 79, if the correction tool 80 is further lowered in this way, the correction tool 80 is parallel to the upper eccentric portion 53. If the upper eccentric portion 53 is further lowered, only the correction tool 80 moves upward along the drop preventing bolt 79, and the spherical washer 78 comes into contact with the correction tool base 75. Thereby, the correction tool 80 is pressed against the correction tool base 75 via the spherical washer 78 while following the upper eccentric portion 53.
When the movement is continued from this state, the slide base 73 moves down along the linear bushing 76 with the correction tool base 75 held in position. At this time, as shown in fig. 6, the compression spring 77 disposed so as to be sandwiched between the correction tool base 75 and the slide base 73 is compressed, and a spring reaction force is generated. The upper eccentric portion correction tool unit 63 is further lowered until the spring reaction force reaches a predetermined value. After the spring reaction force reaches a predetermined value, the crankshaft 50 is rotated by the rotary drive device 30 while maintaining the position of the upper eccentric portion correction tool unit 63.
Fig. 7 is a front cross-sectional view when the crankshaft 50 rotates and the phase is changed in a state in which the upper eccentric portion correction tool unit 63 is pressed against the crankshaft 50. When the crankshaft 50 rotates, the central axis of the upper eccentric portion 53 is not coaxial with the rotation axis, and therefore the position of the central axis changes. With the movement of the position of the center axis, the correction tool base 75 moves up and down along the guide pin 74, and the slide base 73 attached to the slider 72 moves left and right along the guide rail 71. In this way, the correction tool 80 is driven by the rotation of the crankshaft 50 in a state pressed against the upper eccentric portion 53 by the spring reaction force of the compression spring 77.
As described above, the configuration of the tool unit and the movement during the correction process are described using the correction tool unit 63 for the upper eccentric portion. The main shaft portion correction tool unit 61, the auxiliary shaft portion correction tool unit 62, and the lower eccentric portion correction tool unit 64 may be configured in the same manner, but the guide rail 71 and the slider 72 are not required in the case where the main shaft portion correction tool unit 61 and the auxiliary shaft portion correction tool unit 62 are manufactured with high accuracy so that the rotation axis of the crankshaft 50 coincides with the central axes of the main shaft portion 51 and the auxiliary shaft portion 52, which are the machining portions of the respective tool units.
Further, the details of the correction tool 80 for correcting the coated surface of the crankshaft 50 will be described.
Fig. 8 is a front view of the correction tool 80. For the main body 81 using a material much harder than paint such as tool steel, a large round portion 82 and a small round portion 83 are provided, and an edge portion 84 for correcting or removing a convex portion of the painted surface is formed by the large round portion 82 and the small round portion 83. In the present embodiment, the small round portion 83 is provided, but the small round portion need not be circular arc-shaped as long as the groove can form the edge portion 84.
Further, a bolt through hole 85 is provided, and the bolt through hole 85 allows the drop preventing bolt 79 to pass through. The large circular portion 82 has a diameter larger than that of the upper eccentric portion 53 as a processing object, the small circular portion 83 has a diameter smaller than that of the upper eccentric portion 53, and the small circular portion 83 is provided in parallel with the center axis of the large cylindrical portion 82. By forming each portion with high precision, the edge portion 84 is also formed parallel to each central axis.
In the present embodiment, the surface of the large round portion 82 is finished to a very smooth surface having a ten-point average roughness rz1.0 μm or less, but rz1.0 μm or less is not necessarily required, as long as damage is not caused when the correction tool 80 and the crankshaft 50 are slid. For example, it is known that the slidability of the crankshaft 50 can be improved by providing the large rounded portion 82 with fine textures, and that it is not problematic to exceed rz1.0 μm by such processing.
After the small round portion 83 is machined, the large round portion 82 is finished or the like so that burrs generated at the edge portion 84 are not generated in the radial direction of the large round portion 82. The length of the correction tool 80 in the depth direction of the paper surface, in which the large round portion 82 and the small round portion 83 are formed, is set to be longer than the axial length of the upper eccentric portion 53.
Fig. 9 is a front cross-sectional view of the correction tool 80 according to embodiment 1 pressed against the upper eccentric portion 53. The large round portion 82 has a diameter larger than that of the upper eccentric portion 53 as the coating portion, and the small round portion 83 is formed smaller than that of the upper eccentric portion 53 as the coating portion, so that when the correction tool 80 is pressed against the upper eccentric portion 53, the edge portion 84 formed by the large round portion 82 and the small round portion 83 is brought into close contact with the upper eccentric portion 53. When the upper eccentric portion 53 has the convex portion 90 of the coating surface, there is a possibility that the edge portion 84 is not adhered closely at a moment, but if the opening width of the small round portion 83 is made larger than the width of the convex portion 90 of the coating surface, the edge portion 84 and the upper eccentric portion 53 are brought into close adhesion as shown in fig. 8 by rotating the crankshaft 50.
When the crankshaft 50 is rotated from the state shown in fig. 9, the convex portion 90 of the coated surface is cut away by contact with the edge portion 84. The coated surface other than the convex portion 90 is in contact with the smoothly finished round portion 82, and therefore, no damage or the like is caused. Further, the large round portion 82 and the upper eccentric portion 53 are in contact with each other in the concave portion shape and the convex portion shape, and therefore, there is an effect that stress at the contact portion is small and damage is not easily caused.
Further, since the length of the correction tool 80 in the depth direction is set to be longer than the axial length of the upper eccentric portion 53, the entire coated surface of the upper eccentric portion 53 can be corrected by rotating the crankshaft 50 by 1 turn or more. The length of the correction tool 80 in the depth direction may be equal to or longer than the length of the portion to be corrected, or may be shorter than the axial length of the upper eccentric portion 53.
Fig. 10 is a view showing a surface photograph and a cross-sectional shape before and after the coated surface of the crankshaft 50 is processed by the coated surface correction device according to embodiment 1. The horizontal axis of the graph showing the sectional shape represents a dimensionless value of the axial length of the coated surface, and the vertical axis represents a dimensionless value of the height of the coated surface. As described above, it was confirmed that the convex portion 90 can be removed efficiently and reliably without damaging the portion of the coated surface where the convex portion is not present.
As described above, by pressing the correction tool 80 so as to follow the crankshaft 50 as the workpiece and rotating the crankshaft 50, the correction tool 80 has the circular arc having a larger diameter than the coating portion and the groove such as the small circular portion parallel to the circular arc and having a smaller width than the diameter of the coating portion, and thereby the convex portion 90 can be removed efficiently and reliably without damaging the portion of the coating surface of the crankshaft 50 where the convex portion is not present. Here, the groove of the correction tool 80 is preferably parallel to the circular arc, but even if not parallel, the convex portion of the coated surface can be removed as long as the edge portion 84 can be brought into contact with the crankshaft 50.
Embodiment 2.
As in embodiment 1, the correction tool 80 is pressed so as to follow the crankshaft 50 as the workpiece, and the crankshaft 50 is rotated, and the correction tool 80 has a large circular portion 82 as an arc larger than the diameter of the coating portion, and a small circular portion 83 parallel to the large circular portion 82 and having a groove smaller in width than the diameter of the coating portion. In this case, as shown in fig. 11, a wedge portion 86 smoothly connected from the large round portion 82 of the correction tool 80 to the end surface portion 87 may also be provided. With such a configuration, when the correction tool 80 is pressed against the crankshaft 50, the correction tool 80 can be driven along the wedge portion 86 from the upper eccentric portion 53, and therefore, damage due to contact between the end surface portion 87 and the upper eccentric portion 53 can be prevented.
Embodiment 3.
As in embodiment 1, the correction tool 80 is pressed to follow the crankshaft 50 as the workpiece, and the crankshaft 50 is rotated, and the correction tool 80 has a large circular portion 82 as an arc larger than the diameter of the coating portion, and a groove parallel to the large circular portion 82 and having a width smaller than the diameter of the coating portion. In this case, as shown in fig. 12, the correction tool 80 may be formed into a rectangular portion 88. By configuring in this way, the angle of the surface that contacts when the convex portion 90 of the coated surface is removed is a right angle. The cutting tool having a so-called rake angle of 0 ° can be improved in sharpness as compared with the groove formed by the small round portion 83, and the removal performance of the protruding portion can be improved.
While various illustrative embodiments and examples have been described herein, the various features, aspects, and functions described in one or more embodiments are not limited to application to particular embodiments, and can be applied to embodiments alone or in various combinations.
Accordingly, numerous modifications not illustrated are conceivable within the scope of the technology disclosed in the present specification. For example, the case where at least one component is deformed, the case where addition is performed or the case where omission is performed, and the case where at least one component is extracted and combined with the components of other embodiments are included.
