Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to a positioning mechanism and processing device. Background Technology

[0002] The half-shaft is a solid shaft that transmits torque between the differential and the drive wheels. Existing half-shafts generally have machining allowances after forging, so the blank parts will be precision turned on the end face and a center hole will be machined on the end face. Because the machining accuracy requirements of the half-shaft end face and center hole are high, the half-shaft of the axle is relatively long, the half-shaft clamping is difficult, and runout is prone to occur, resulting in unevenness of the half-shaft end face and deviation of the center hole positioning. Summary of the Invention

Multiple jaws of the hollow chuck are used to collectively clamp the other end of the half-shaft.

[0007] A support assembly includes a support portion and a support portion. The support portion is located on the left side of the rotating shaft and forms an installation channel extending in the left-right direction.

[0018] A pressing assembly is disposed on the upper end face of the limiting plate and located on one side of the groove in the left-right direction. The pressing assembly has a pressing part that is movably disposed in the up-down direction so as to be able to abut against the upper end face of the abutting part.

[0019] Optionally, the support assembly further includes a support plate mounted on the base, and the upper end surface of the support plate is provided with a slide rail extending in the left-right direction;

[0049] The half-shaft is a solid shaft that transmits torque between the differential and the drive wheels. Existing half-shafts generally have machining allowances after forging, so the blank parts will be precision turned on the end face and a center hole will be machined on the end face. Because the machining accuracy requirements of the half-shaft end face and center hole are high, the half-shaft of the axle is relatively long, the half-shaft clamping is difficult, and runout is prone to occur, resulting in unevenness of the half-shaft end face and deviation of the center hole positioning.

[0050] In view of this, the present invention proposes a positioning mechanism that, through the cooperation of the clamping mechanism and the support component, clamps and limits the half-shaft to prevent runout during machining, thereby ensuring the machining accuracy of the end face and center hole of the half-shaft. Figure 1 and Figure 4 The image shows an embodiment of the positioning mechanism provided by the present invention.

[0051] like Figure 1 and Figure 4As shown, the positioning mechanism 100 proposed in this invention includes a base 1, a clamping mechanism 2, and a support assembly 3. The clamping mechanism 2 includes a hollow chuck 21 and a hollow rotating shaft 22. The rotating shaft 22 is rotatably mounted above the base 1 along a left-right extending axis. The hollow chuck 21 is mounted on the right end of the rotating shaft 22. The through hole on the chuck body of the hollow chuck 21 corresponds to the inner cavity of the rotating shaft 22, allowing the other end of the half-shaft to pass through. Multiple jaws of the hollow chuck 21 are used to clamp together. The other end of the half shaft; the support assembly 3 includes a support part 31 and a support part 32. The support part 31 is located on the left side of the rotating shaft 22 and forms an installation channel 31a extending in the left and right direction. The support part 32 is rotatably installed in the installation channel 31a along the axis extending in the left and right direction and forms a receiving groove 32a with the slot facing to the right. The support part 31 is swingable in the front and back direction so that it can move to be spaced apart from and opposite to the rotating shaft 22, so that the receiving groove 32a can accommodate the connecting boss.

[0052] In the technical solution of this invention, during the end face cutting and center hole machining of the half-shaft, the other end of the half-shaft (opposite to the end on which the flange is mounted in the length direction of the half-shaft) sequentially passes through the cavity of the rotating shaft 22 and the through hole on the chuck body of the hollow chuck 21, so that it is partially located at the right end of the hollow chuck 21 and is clamped by multiple jaws. The end on which the flange is mounted on the half-shaft is accommodated by the receiving groove 32a of the support part 32 to receive the connecting boss on the flange, and the support part 32 is rotatable along the axis extending in the left and right directions. In this way, through the cooperation of the clamping mechanism 2 and the support component 3, the half-shaft is clamped and limited to avoid the half-shaft from running during machining, so as to ensure the machining accuracy of the end face and center hole of the half-shaft.

[0053] In this embodiment, as Figures 1 to 3As shown, the support assembly 3 also includes a mounting base 33, a connecting arm 34, and a support arm 35. The mounting base 33 is located on the upper end face of the base body 1 and to the left of the rotating shaft 22. The mounting base 33 is movably arranged in the left-right direction. One end of the connecting arm 34 is fixedly connected to the front side of the support part 31, and the other end is rotatably mounted on the mounting base 33 along the left-right axis. One end of the support arm 35 is fixedly connected to the rear side of the support part 31, and the other end forms an abutment part 35a for abutting against the upper end face of the mounting base 33. By rotating the connecting arm 34, the support part 31 can swing back and forth. Thus, during the installation of the half-shaft, the support part 31 is swung away from the rotating shaft 22 to avoid the half-shaft. After the other end of the half-shaft is clamped by the hollow chuck 21, the distance between the mounting base 33 and the rotating shaft 22 is adjusted, and the support part 31 is swung closer to the rotating shaft 22. This makes the support part 31 and the rotating shaft 22 spaced apart and opposite to each other, so that the receiving groove 32a can accommodate the connecting boss to support the end of the half-shaft with the flange. At this time, the support arm 35 abuts against the upper end surface of the mounting base 33 to work together with the connecting arm 34 to support and limit the support part 31, preventing the half-shaft from jumping during processing due to its long length. The mounting base 33 is movable in the left and right direction so that the positioning mechanism 100 can be used to process half-shafts of different lengths, improving the usability of the positioning mechanism 100.

[0054] In this embodiment, as Figures 1 to 3 As shown, the connecting arm 34 and the supporting arm 35 are arranged opposite each other in the front-rear direction. The connecting arm 34 is inclined downwards towards the direction opposite to the supporting part 31, and its upper end is fixedly connected to the front side of the supporting part 31. The supporting arm 35 includes a first supporting segment 351 and a second supporting segment 352 arranged sequentially in the front-rear direction. The first supporting segment 351 is inclined downwards towards the direction opposite to the supporting part 31, and its upper end is fixedly connected to the rear side of the supporting part 31. The second supporting segment 352 extends in the front-rear direction. The abutment part 35a includes the second supporting segment 352. By forming a triangular structure with the connecting arm 34, the supporting arm 35, and the supporting part 31, the support stability of the supporting part 31 can be improved, while simplifying the structure of the supporting assembly 3. The second supporting segment 352 extends in the front-rear direction to increase the contact area with the mounting base 33, improving the abutment reliability and enhancing the load-bearing capacity of the supporting assembly 3.

[0055] In this embodiment, as Figure 1 and Figure 2As shown, the support assembly 3 further includes a limiting structure 36, which includes a limiting plate 361 and a pressing assembly (not shown in the figure). The limiting plate 361 is mounted on the upper end face of the mounting base 33. The upper end face of the limiting plate 361 has a groove 361a. The groove 361a has two side walls in the front-rear direction that penetrate the limiting plate 361 to accommodate the abutment portion 35a. The pressing assembly is located on the upper end face of the limiting plate 361 and on one side of the groove 361a in the left-right direction. The pressing assembly has a pressing part that is movable in the up-down direction to abut against the upper end face of the abutment portion 35a. By setting the limiting plate 361 and the pressing assembly, the support arm 35 is limited and pressed, improving the abutment reliability between the support arm 35 and the mounting base 33 and ensuring the support stability of the support arm 35.

[0056] In this embodiment, as Figure 2 As shown, the support assembly 3 further includes a bearing plate 37 mounted on the base 1. The upper end surface of the bearing plate 37 is provided with a slide rail 371 extending in the left-right direction. The lower end surface of the mounting base 33 is provided with a sliding groove corresponding to the slide rail 371. The sliding groove cooperates with the slide rail 371 to allow the mounting base 33 to move in the left-right direction. The cooperation between the slide rail 371 and the sliding groove ensures the straightness of the mounting base 33's linear movement in the left-right direction, so that the relative position of the mounting base 33 and the rotating shaft 22 in the front-back upward direction remains unchanged. This ensures that after the support part 31 swings towards the rotating shaft 22 to its position, it can be spaced apart from and opposite to the rotating shaft 22.

[0057] In this embodiment, as Figure 4 As shown, the support portion 32 includes a support member 321 and a bushing 322. The support member 321 includes a connecting shaft 3211 and a mounting portion 3212. The connecting shaft 3211 passes through the mounting channel 31a and is rotatably disposed along a left-right extending axis. The mounting portion 3212 is located at the right end of the connecting shaft 3211, and the right end face of the mounting portion 3212 is recessed to form the receiving groove 32a. The bushing 322 is installed in the receiving groove 32a and is used to fit over the outside of the connecting boss. The bushing 322 is rotatably disposed along the left-right extending axis, so that after engaging with the outside of the connecting boss, it can rotate with the half shaft to achieve support and limitation of the end of the half shaft with a flange during half shaft machining.

[0058] Furthermore, in this embodiment, the bushing 322 is detachably connected to the mounting portion 3212. Thus, by replacing the bushing 322 with one of different inner diameters, it can be adapted to support the machining of half-shafts of different diameters, improving the versatility of the positioning mechanism 100.

[0059] In this embodiment, as Figure 1 and Figure 2 As shown, the clamping mechanism 2 further includes a drive motor 23 and a transmission structure 24. The drive motor 23 is located on the base 1 and in front of the support assembly 3, with its output shaft extending laterally. The transmission structure 24 includes a first pulley, a second pulley 241, and a transmission belt. The first pulley is mounted on the output shaft of the drive motor 23, the second pulley 241 is fixedly sleeved on the left end of the rotating shaft 22, and the transmission belt is sleeved on the outside of the first pulley and the second pulley 241 to transmit the rotation of the output shaft to the rotating shaft 22, thereby driving the hollow chuck 21 to rotate. Thus, the rotation of the output shaft of the drive motor 23 is transmitted to the rotating shaft 22 via the transmission belt, causing the half-shaft to rotate under the drive of the rotating shaft 22, thereby meeting the needs of half-shaft end face cutting and center hole machining.

[0060] The present invention also proposes a processing device 200, which includes a positioning mechanism 100, a base 210, a cutting mechanism 220, and a cutting drive mechanism 230. The base 210 forms the seat 1 of the positioning mechanism 100. The cutting mechanism 220 includes a first support plate 2201, a second support plate 2202, and a tool holder 2203. The first support plate 2201 is slidably mounted on the base 210 in the left-right direction and is located in front of the positioning mechanism 100. The second support plate 2202 is slidably mounted on the upper end surface of the first support plate 2201 in the front-back direction. The tool holder 2203 is disposed on the upper end surface of the second support plate 2202 and is located close to the positioning mechanism 100 for mounting a tool. The cutting drive mechanism 230 includes two first linear motors 2301 mounted on the upper end surface of the base 1. The two first linear motors 2301 are respectively driven connected to the first support plate 2201 and the second support plate 2202. Thus, when the first support plate 2201 slides, the tool holder 2203 moves, which can drive the tool on it to move axially along the half shaft to realize the outer circle cutting of the half shaft, thereby facilitating the spline setting. When the second support plate 2202 slides, the tool holder 2203 moves, which can drive the tool on it to move radially along the half shaft to realize the end face cutting of the half shaft, so as to facilitate further machining of the center hole.

[0061] In this embodiment, as Figure 1As shown, the machining device 200 also includes a tailstock 240 and a second linear motor 250. The tailstock 240 is mounted on the base 210 and located on the right side of the positioning mechanism 100. The tailstock 240 forms a receiving channel extending in the left-right direction, and a sleeve is provided in the receiving channel for mounting a center drill. The sleeve is movable in the left-right direction. The second linear motor 250 is mounted on the right side of the tailstock 240, and the output shaft of the second linear motor 250 is drivenly connected to the sleeve. By setting the tailstock 240 to facilitate the mounting of the center drill, the end face and outer circle of the half-shaft can be cut in one clamping, ensuring machining accuracy.

[0062] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
