Description

Technical Field

[0001] This invention belongs to the field of end face grinding technology, specifically referring to a deburring mechanism for the end face of an inner ball cage. Background Technology

[0002] The inner CV joint is a transmission component that connects the gearbox and the half-shaft, and can maintain power transmission when the angle of the half-shaft changes. The inner CV joint is mainly composed of core components such as the three-way bearing and the CV joint housing. After the mating parts of these components are processed, the edges need to be chamfered and deburred to avoid too much iron filings falling off during use and causing wear on the parts.

[0003] Among the aforementioned parts, the most complex in structure and the one with the highest need for deburring is the support frame of the three-way bearing. Its complex structure makes it difficult for ordinary automatic grinding devices to match. If a ball mill or similar equipment used for surface polishing of irregularly shaped parts is used, it may affect the precision of the parts that mate with the bearing. Therefore, deburring of such parts is currently mostly done manually. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention proposes an end-face deburring mechanism capable of automatically adjusting the workpiece position and pushing the workpiece to change its angle. This solution uses magnetic attraction to achieve a non-locking connection between the three-pronged bearing bracket and the workpiece. During the descent of the three-pronged bearing bracket, the axial position of the bracket is adjusted planarly by the chamfer at the top of the workpiece loading shaft. Then, the angle of the three-pronged bearing bracket is guided and adjusted by a diagonal brace. This ensures the accuracy of the grinding orientation and avoids misalignment and interference with the mating teeth.

[0005] During the deburring process, the slide plate drives the elastic rod to reciprocate, which enables unidirectional rotation of the three-pronged rotating rod. Combined with the three static hovering angles of the misalignment actuation component, the workpiece can be automatically rotated and moved forward.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a deburring mechanism for the end face of an inner ball cage, including a misalignment actuation assembly, a one-way barb assembly, a workpiece repositioning assembly, a guide frame, a pickup unit, a sleeve-type grinding mechanism, a transverse drive assembly, and a mounting base plate. The transverse drive assembly is disposed on the mounting base plate, the sleeve-type grinding mechanism is disposed on the transverse drive assembly, the misalignment actuation assembly is disposed on the mounting base plate, the one-way barb assembly is disposed on the transverse drive assembly, and the workpiece repositioning assembly is disposed in the misalignment actuation assembly. The guide frame and the pickup unit are mounted on the mounting base plate. The guide frame is provided with cantilever struts evenly distributed in a ring. The ends of the cantilever struts are symmetrically provided with diagonal struts. The workpiece can be guided to the correct initial angle by the diagonal struts.

[0007] The three-pronged bearing bracket and the annular electromagnet connected by magnetic attraction can rotate. Therefore, during the descent of the three-pronged bearing bracket, it will adjust its own angle under the guidance of the diagonal brace. On the one hand, this allows the initial angle of the three-pronged bearing bracket to face the sleeve-type grinding mechanism, and on the other hand, it ensures that the three-pronged bearing bracket and the mating teeth are engaged and matched.

[0008] Furthermore, the misalignment actuation assembly includes a lower fixed sleeve, an upper rotating sleeve, a tension spring, and a three-pronged rotating rod. The lower fixed sleeve is fixedly connected to the mounting base plate. The upper rotating sleeve and the lower fixed sleeve are coaxially arranged. The tension spring is located between the lower fixed sleeve and the upper rotating sleeve and allows the upper rotating sleeve to rotate. The three-pronged rotating rod is fixedly connected to the upper rotating sleeve, and cantilever ends are evenly distributed in a ring on the three-pronged rotating rod.

[0009] Under the tension of the tension spring, the lower fixed sleeve and the upper rotating sleeve have only three static suspension positions, which correspond to the three shafts of the three-pronged bearing bracket that need to be ground. This means that when the one-way hook assembly moves the three-pronged rotating rod more than 60 degrees, the upper rotating sleeve will drive the three-pronged bearing bracket to continue rotating until the next working angle.

[0010] Furthermore, the one-way barb assembly includes an elastic rod, a hinge shaft, and a limiting barb. The end of the elastic rod is provided with a hinge seat, and the limiting barb and the hinge seat are hinged together by the hinge shaft. A torsion spring sleeved on the hinge shaft is provided between the elastic rod and the limiting barb.

[0011] The skateboard drives the elastic rod to slide back and forth. By rotating the limit hook in one direction, the three-pronged rod can be adjusted in one direction. By switching the engagement state of the limit hook and the cantilever end, the problem of the three-pronged rod rotating back and forth can be avoided.

[0012] Furthermore, the workpiece repositioning assembly includes a workpiece loading shaft and a three-pronged bearing bracket. The workpiece loading shaft is fixedly connected to the upper rotating sleeve and slidably disposed in the lower fixed sleeve. The workpiece loading shaft is provided with mating teeth that cooperate with the three-pronged bearing bracket.

[0013] By chamfering the top of the workpiece loading shaft, the three-pronged bearing bracket located on the annular electromagnet can be positioned axially, so that the three-pronged bearing bracket is changed to a position coaxial with the workpiece loading shaft. Combined with the angle adjustment function of the guide frame, the three-pronged bearing bracket can be guided in both lateral position and angle dimensions.

[0014] By matching the tooth groove between the gear and the three-pronged bearing bracket, the radial clearance between the three-pronged bearing bracket and the workpiece loading shaft can be basically eliminated while the three-pronged bearing bracket can slide longitudinally relative to the workpiece loading shaft. This solves the technical contradiction of having a clearance between the workpiece loading shaft and the three-pronged bearing bracket, but also eliminating the need for a clearance.

[0015] Preferably, the workpiece repositioning assembly further includes a height adjusting nut, and a threaded portion is provided below the mating teeth, with the height adjusting nut and the threaded portion engaging threadedly.

[0016] Furthermore, the pickup unit is equipped with a lifting rod, and the end of the lifting rod is equipped with a ring electromagnet capable of attracting the three-pronged bearing bracket.

[0017] The ring electromagnet is connected to the three-pronged bearing bracket by magnetic attraction, which can not only overcome the gravity of the three-pronged bearing bracket to move the three-pronged bearing bracket, but also allow the three-pronged bearing bracket to be moved and adjusted by other parts.

[0018] Furthermore, the sleeve-type grinding mechanism includes a grinding sleeve and a grinding liner, wherein the grinding liner is detachably disposed in the grinding sleeve.

[0019] Preferably, the sleeve-type grinding mechanism further includes a support base, a grinding bearing, and a grinding motor. The support base is disposed on the transverse drive assembly, the grinding bearing is disposed between the support base and the grinding sleeve, the grinding motor is disposed on the transverse drive assembly, and the output shaft of the grinding motor is connected to the grinding sleeve.

[0020] Furthermore, the transverse drive assembly includes a base, a lead screw base, and a sliding plate. The base is disposed on a mounting plate, the lead screw base is disposed on the base, and the sliding plate is disposed on the slider of the lead screw base.

[0021] The support base and grinding motor are located above the slide plate, and the elastic rod is located below the slide plate.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The three-pronged bearing bracket and the ring electromagnet connected by magnetic attraction can rotate. Therefore, the angle of the three-pronged bearing bracket will be adjusted under the guidance of the diagonal brace during the descent. On the one hand, the initial angle of the three-pronged bearing bracket is oriented towards the sleeve-type grinding mechanism. On the other hand, it can also ensure that the three-pronged bearing bracket and the mating teeth are engaged and matched.

[0023] (2) Under the tension of the tension spring, the lower fixed sleeve and the upper rotating sleeve have only three static suspension positions, which correspond to the three shafts of the three-pronged bearing bracket that need to be polished. Thus, when the one-way hook assembly moves the three-pronged rotating rod more than 60 degrees, the upper rotating sleeve will drive the three-pronged bearing bracket to continue rotating until the next working angle.

[0024] (3) The slide plate drives the elastic rod to slide back and forth. By the unidirectional rotation of the limit hook, the three-pronged rod can be adjusted in one direction. By switching the combination state of the limit hook and the cantilever end, the problem of the three-pronged rod rotating back and forth can be avoided.

[0025] (4) By chamfering the top of the workpiece loading shaft, the three-pronged bearing bracket located on the annular electromagnet can be positioned axially, so that the three-pronged bearing bracket is changed to a position coaxial with the workpiece loading shaft. Combined with the angle adjustment function of the guide frame, the three-pronged bearing bracket can be guided in two dimensions: lateral position and angle.

[0026] (5) By matching the tooth groove between the gear and the three-way bearing bracket, the radial clearance between the three-way bearing bracket and the workpiece loading shaft can be basically eliminated while the three-way bearing bracket can slide longitudinally relative to the workpiece loading shaft. This solves the technical contradiction between the workpiece loading shaft and the three-way bearing bracket, which requires both a clearance (to avoid the three-way bearing bracket and the workpiece loading shaft being difficult to disassemble due to interference fit) and no clearance (intermittent movement will cause the workpiece to shake and affect the machining accuracy).

[0027] (6) The ring electromagnet is connected to the three-pronged bearing bracket by magnetic attraction, which can not only overcome the gravity of the three-pronged bearing bracket to move the three-pronged bearing bracket, but also allow the three-pronged bearing bracket to be moved and adjusted by other parts.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] like Figures 1-10As shown, the present invention proposes a deburring mechanism for the end face of an inner ball cage, including a misalignment actuation assembly 1, a one-way barb assembly 2, a workpiece repositioning assembly 3, a guide frame 4, a pickup unit 5, a sleeve-type grinding mechanism 6, a transverse drive assembly 7, and a mounting base plate 8. The transverse drive assembly 7 is mounted on the mounting base plate 8, the sleeve-type grinding mechanism 6 is mounted on the transverse drive assembly 7, the misalignment actuation assembly 1 is mounted on the mounting base plate 8, the one-way barb assembly 2 is mounted on the transverse drive assembly 7, and the workpiece repositioning assembly 3 is located in the misalignment actuation assembly 1. The guide frame 4 and the pickup unit 5 are mounted on the mounting base plate 8. The guide frame 4 is provided with cantilever struts 41 evenly distributed in a ring. The ends of the cantilever struts 41 are symmetrically provided with diagonal struts 42. The workpiece can be guided to the correct initial angle by the diagonal struts 42.

[0034] The three-pronged bearing bracket 33 and the annular electromagnet 52 connected by magnetic attraction can rotate. Therefore, during the descent of the three-pronged bearing bracket 33, its angle will be adjusted under the guidance of the diagonal brace 42. On the one hand, this allows the initial angle of the three-pronged bearing bracket 33 to face the sleeve-type grinding mechanism 6, and on the other hand, it ensures that the three-pronged bearing bracket 33 and the mating teeth 311 are engaged and matched.

[0035] The misalignment actuation assembly 1 includes a lower fixed sleeve 11, an upper rotating sleeve 12, a tension spring 13, and a three-pronged rotating rod 14. The lower fixed sleeve 11 is fixedly connected to the mounting base plate 8. The upper rotating sleeve 12 and the lower fixed sleeve 11 are coaxially arranged. The tension spring 13 is located between the lower fixed sleeve 11 and the upper rotating sleeve 12 and allows the upper rotating sleeve 12 to rotate. The three-pronged rotating rod 14 is fixedly connected to the upper rotating sleeve 12. The three-pronged rotating rod 14 has cantilever ends 141 evenly distributed in a ring on it.

[0036] Under the tension of the tension spring 13, the lower fixed sleeve 11 and the upper rotating sleeve 12 have only three static suspension positions, which correspond to the three shafts of the three-pronged bearing bracket 33 that need to be polished. This means that when the one-way barb assembly 2 moves the three-pronged rotating rod 14 more than 60 degrees, the upper rotating sleeve 12 will drive the three-pronged bearing bracket 33 to continue rotating until the next working angle.

[0037] The one-way barb assembly 2 includes an elastic rod 21, a hinge shaft 22, and a limiting barb 23. The end of the elastic rod 21 is provided with a hinge seat 211. The limiting barb 23 and the hinge seat 211 are hinged together by the hinge shaft 22. A torsion spring sleeved on the hinge shaft 22 is provided between the elastic rod 21 and the limiting barb 23.

[0038] The slide plate 73 drives the elastic rod 21 to slide back and forth. By rotating the limit hook 23 in one direction, the three-pronged rotating rod 14 can be adjusted in one direction. By switching the engagement state of the limit hook 23 and the cantilever end 141, the problem of the three-pronged rotating rod 14 rotating back and forth can be avoided.

[0039] The workpiece transposition assembly 3 includes a workpiece loading shaft 31 and a three-pronged bearing bracket 33. The workpiece loading shaft 31 is fixedly connected to the upper rotating sleeve 12 and slidably disposed in the lower fixed sleeve 11. The workpiece loading shaft 31 is provided with mating teeth 311 that cooperate with the three-pronged bearing bracket 33.

[0040] By using the chamfer at the top of the workpiece loading shaft 31, the three-pronged bearing bracket 33 located on the annular electromagnet 52 can be positioned axially, so that the three-pronged bearing bracket 33 is changed to a position coaxial with the workpiece loading shaft 31. Combined with the angle adjustment function of the guide frame 4, the three-pronged bearing bracket 33 can be guided in both lateral position and angle dimensions.

[0041] By matching the tooth groove between the gear 311 and the three-pronged bearing bracket 33, the radial clearance between the three-pronged bearing bracket 33 and the workpiece loading shaft 31 is basically eliminated while the three-pronged bearing bracket 33 can slide longitudinally relative to the workpiece loading shaft 31. This solves the technical contradiction that the workpiece loading shaft 31 and the three-pronged bearing bracket 33 must have a clearance, but cannot have a clearance at all.

[0042] The workpiece shifting assembly 3 also includes a height adjusting nut 32, and a threaded portion 312 is provided below the mating teeth 311, with the height adjusting nut 32 and the threaded portion 312 being threadedly engaged.

[0043] The pickup unit 5 is equipped with a lifting rod 51, and the end of the lifting rod 51 is equipped with a ring electromagnet 52 that can attract the three-pronged bearing bracket 33.

[0044] The ring electromagnet 52 is connected to the three-pronged bearing bracket 33 by magnetic attraction, which can overcome the gravity of the three-pronged bearing bracket 33 to move the three-pronged bearing bracket 33, and also allow the three-pronged bearing bracket 33 to be moved and adjusted by other parts.

[0045] The sleeve-type grinding mechanism 6 includes a grinding sleeve 63 and a grinding liner 64, the grinding liner 64 being detachably disposed in the grinding sleeve 63.

[0046] The sleeve-type grinding mechanism 6 also includes a support base 61, a grinding bearing 62, and a grinding motor 65. The support base 61 is located on the transverse drive assembly 7, the grinding bearing 62 is located between the support base 61 and the grinding sleeve 63, and the grinding motor 65 is located on the transverse drive assembly 7. The output shaft of the grinding motor 65 is connected to the grinding sleeve 63.

[0047] The transverse drive assembly 7 includes a base 71, a lead screw base 72, and a slide plate 73. The base 71 is mounted on the mounting base plate 8, the lead screw base 72 is mounted on the base 71, and the slide plate 73 is mounted on the slider of the lead screw base 72.

[0048] The support base 61 and the grinding motor 65 are located above the slide plate 73, and the elastic long rod 21 is located below the slide plate 73.

[0049] In practical use, the three-pronged bearing bracket 33 is first placed below the annular electromagnet 52 by an external robotic arm. The three-pronged bearing bracket 33 and the annular electromagnet 52 are connected by magnetic attraction. At this time, the three-pronged bearing bracket 33 and the annular electromagnet 52 are approximately coaxial. After the picking unit 5 transfers the three-pronged bearing bracket 33 above the workpiece loading shaft 31, the lifting rod 51 lowers the three-pronged bearing bracket 33. The chamfer on the top of the workpiece loading shaft 31 allows for in-plane adjustment of the position of the central axis of the three-pronged bearing bracket 33. When the three-pronged bearing bracket 33 and the workpiece loading shaft 31 are coaxial, the three-pronged bearing bracket 33 can continue to descend and be fitted onto the workpiece loading shaft 31.

[0050] During the descent of the three-pronged bearing bracket 33, the horizontal axis on the outer side of the three-pronged bearing bracket 33 will contact and abut against the diagonal brace 42. Under the guidance of the diagonal brace 42, the angle of the three-pronged bearing bracket 33 will be gradually adjusted until one of the horizontal axes on the outer side of the three-pronged bearing bracket 33 points to the sleeve-type grinding mechanism 6, and the tooth groove feature on the three-pronged bearing bracket 33 corresponds to the angle of the mating tooth 311.

[0051] The three-pronged bearing bracket 33 continues to descend and is fitted onto the mating gear 311 until the bottom of the three-pronged bearing bracket 33 abuts against the height adjusting nut 32; thereafter, the angle of the three-pronged bearing bracket 33 will change with the angle of the workpiece loading shaft 31, and the annular electromagnet 52 will rise and reset after being de-energized.

[0052] Then start the grinding motor 65, which drives the grinding sleeve 63 to rotate the grinding liner 64, and drives the slide plate 73 to slide and approach the three-pronged bearing bracket 33 through the lead screw base 72. During this process, the limiting hook 23 will first contact the cantilever end 141. At this time, the limiting hook 23 will rotate against the elastic force of the torsion spring and will not change the angle of the three-pronged rotating rod 14. After the rotating polishing liner 64 contacts the side shaft of the three-pronged bearing bracket 33, it will polish and deburr the end of the shaft.

[0053] After grinding is completed, the lead screw base 72 drives the slide plate 73 to reset, the grinding liner 64 moves away from the workpiece, and at the same time drives the elastic rod 21 to reset. When the limit hook 23 resets, it will hook the cantilever end 141. Since the limit hook 23 can only rotate in one direction, the limit hook 23 will drive the triangular rod 14 to rotate through the cantilever end 141. During the rotation of the triangular rod 14, the elastic rod 21 will avoid being jammed laterally due to its own elastic deformation.

[0054] When the triangular rotating rod 14 rotates, the upper rotating sleeve 12 will move up slightly and rotate. As long as the rotation angle of the triangular rotating rod 14 exceeds 60 degrees, even if the rotation driving force is lost, the upper rotating sleeve 12 will continue to rotate under the elastic force of the tension spring 13 until it reaches the next stationary hovering angle. Then, the other side shaft of the triangular bearing bracket 33 corresponds to the sleeve-type grinding mechanism 6, and the sleeve-type grinding mechanism 6 approaches the workpiece for grinding.

[0055] After all the side shafts of the three-pronged bearing bracket 33 have been ground, the sleeve-type grinding mechanism 6 moves away from the workpiece, the lifting rod 51 drives the annular electromagnet 52 to descend and approach the workpiece, and then the annular electromagnet 52 is energized to generate an attraction force that attracts the three-pronged bearing bracket 33. Subsequently, the upward movement of the lifting rod 51 will move the three-pronged bearing bracket 33 upward and away from the workpiece loading shaft 31. Finally, the processed three-pronged bearing bracket 33 can be removed by an external robotic arm.

[0056] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
