[0029] like Figure 1-4As shown, the specific implementation adopts the following technical solution:

[0030] This specific embodiment includes a frame, a worktable 2, and a loading platform 7. Both the worktable 2 and the loading platform 7 are fixedly mounted on the frame. A horizontal stepping unit 3 is fixedly mounted on the frame, with one end of the horizontal stepping unit 3 positioned above the worktable 2 and the other end positioned above the loading platform 7. A vertical stepping unit 4 is fixedly mounted on the stepper seat of the horizontal stepping unit 3, and a clamping stepping unit 5 is fixedly mounted on the stepper seat of the vertical stepping unit 4. A clamping claw 6 is fixedly mounted on the movable end of the clamping stepping unit 5. A mounting frame 8 is fixedly mounted on the loading platform 7, and the interior of the mounting frame 8 is equidistantly distributed. The mounting bracket 8 has three panels 10, with the upper surface of each panel 10 flush with the upper surface of the mounting frame 8. A support frame 17 is fixedly mounted on the mounting frame 8. A threaded sleeve 18 is screwed onto the support frame 17 via a bearing. A threaded rod 19 is threadedly inserted into the threaded sleeve 18. Stops 20 are fixedly mounted at both ends of the threaded rod 19. A spline guide sleeve 21 is fixedly mounted on the support frame 17. The threaded rod 19 passes through the spline guide sleeve 21. A keyway is formed on the side wall of the threaded rod 19. The threaded rod 19 is guided and engaged with the key block inside the spline guide sleeve 21 via the keyway. A lifting seat 14 is movably fitted between the key guide sleeve 21 and the upper stop block 20. Connecting rods 15 are rotatably mounted on the side wall of the lifting seat 14 at equal angles via a rotating shaft. A support slider 11 is rotatably mounted on the upper end of the connecting rod 15 via a rotating shaft, and the support slider 11 is positioned between two adjacent panels 10. A positioning pin 9 is fixedly mounted on the upper surface of the support slider 11, and the upper end of the positioning pin 9 extends above the mounting bracket 8. A support groove 12 is provided on the side wall of the panel 10, and the support slider 11 is slidably mounted in the support groove 12. A support rod 13 is fixedly mounted on the inner side wall of the mounting bracket 8. The support rod 13 is set between two adjacent panels 10, the support slider 11 is movably sleeved on the support rod 13, the mounting bracket 8 is fixedly set with a lifting push rod 16, the output shaft of the lifting push rod 16 is fixedly set with a guide rod 22, and the guide rod 22 is movably inserted on the lifting seat 14. The upper end of the guide rod 22 is fixedly set with a limit block 23, and the guide rod 22 is fixedly set with a support block 24 below the lifting seat 14. The guide rod 22 is sleeved with a support spring 25, wherein the upper end of the support spring 25 abuts against the lifting seat 14, and the lower end of the support spring 25 abuts against the support block 24.Two mounting rings 26 are screwed onto the upper end of the mounting bracket 8 via bearings. Guide frames 27 are fixedly mounted on the mounting rings 26, positioned on the outer side of the mounting bracket 8. The upper end of the guide frame 27 extends above the mounting bracket 8. Positioning rods 28 are threaded through the guide frame 27, abutting against the upper surface of the panel 10. The two positioning rods 28 are symmetrically arranged. A gear frame 29 is fixedly mounted on the mounting bracket 8, positioned on the outer side of the two mounting rings 26. Drive shafts 30 are screwed onto the upper and lower side plates of the gear frame 29 via bearings. The two drive shafts 30 are connected to the two mounting rings 26 via spur gear sets. A reversing shaft 31 is screwed onto the gear frame 29 via bearings. The reversing shaft 31 is connected to the upper and lower drive shafts 30 via bevel gear sets, thus enabling the upper and lower drive shafts 30 to rotate synchronously in opposite directions via the reversing shaft 31.

[0031] When using this device, the positioning pin 9 opens to limit the snap ring, and the positioning rod 28 closes to position the snap ring head. The opening degree of the positioning pin 9 is adjusted according to the inner diameter of the snap ring, and the distance between the inner end of the positioning rod 28 and the center of the mounting ring 26 is adjusted according to the outer diameter of the snap ring, so that when the positioning pin 9 opens, it precisely supports the inner side of the snap ring, and the inner end of the positioning rod 28 precisely abuts against the outer side of the snap ring. When the lifting seat 14 moves upward, the connecting rod 15 pushes the support slider 11 to open, thus opening the positioning pin 9. Therefore, by limiting the upward movement of the lifting seat 14, the opening degree of the positioning pin 9 is limited. The distance between the inner diameter of the snap ring and the center of the mounting ring 26 is adjusted according to the inner diameter of the snap ring. The threaded rod 19 is supported and guided to move up and down by the spline guide sleeve 21. By rotating the threaded sleeve 18, the threaded rod 19 is pushed up and down, thereby adjusting the height position of the threaded rod 19 and its upper end stop 20, thus limiting the rising position of the lifting seat 14, that is, limiting the opening degree of the positioning pin 9 to match the inner ring radius of the snap ring. When placing the snap ring, the guide rod 22 is first pulled down by the lifting push rod 16. The guide rod 22 abuts against the lifting seat 14 through the limit block 23 at its upper end and pulls the lifting seat 14 down. The lifting seat 14 is sleeved on the threaded rod 19 for guidance and support and moves up and down. The lifting seat 14 moves down and is pulled by the connecting rod 15. When the support slider 11 closes, it moves linearly through the support groove 12 and support rod 13, thus closing and causing the positioning pin 9 to close. After the positioning pin 9 closes, the retaining ring is placed on the panel 10, with the positioning pin 9 passing through it. Simultaneously, the spring head of the retaining ring is positioned between the two positioning rods 28. Then, the lifting push rod 16 pushes the guide rod 22 upwards. The guide rod 22 is supported by the support spring 25 and pushes the lifting seat 14 upwards. The lifting seat 14 then pushes the support slider 11 through the connecting rod 15, causing the support slider 11 to open the positioning pin 9, thus allowing the positioning pin 9 to support the inner ring side of the retaining ring. The spring clip is supported, and when the lifting seat 14 rises and abuts against the stop block 20 at the upper end of the threaded rod 19 and the guide rod 22 continues to rise, the support block 24 cooperates with the lifting seat 14 to press the support spring 25, and then pushes one of the mounting rings 26. The mounting ring 26 drives the drive shaft 30 linked with it through the spur gear set, and drives the drive shaft 30 on the other side and the other mounting ring 26 to rotate through the reversing shaft 31. The two mounting rings 26 rotate in opposite directions, so that the two mounting rings 26 drive their respective positioning rods 28 to rotate through their respective guide frames 27, so that the two positioning rods 28 close and clamp the spring head of the spring clip, thereby achieving the positioning of the spring clip;Next, the horizontal stepping unit 3 drives the vertical stepping unit 4 to move above the material carrier. The vertical stepping unit 4 then drives the clamping stepping unit 5 to descend, thereby clamping the clamping jaws 6 onto the retaining ring. The clamping stepping unit 5 then drives the clamping jaws 6 to open and hold the retaining ring. The retaining ring is then lifted and moved above the worktable 2. The motor is placed on the worktable 2, and the opened retaining ring is lowered and placed onto the motor shaft. Finally, the clamping jaws 6 close to release the retaining ring and place it onto the motor shaft, thus completing the retaining ring assembly.

[0032] Compared with the prior art, the beneficial effects of this utility model are:

[0033] 1. This device uses a closable positioning pin 9 and a closable positioning rod 28 to position the snap ring to be assembled, thereby facilitating the opening and assembly of the positioned snap ring by the clamping claw 6 of this device.

[0034] 2. This device uses the cooperation of the lifting seat 14 and connecting rod 15 with the support slider 11, and the support rod 13 to guide the support slider 11, so that the lifting seat 14 can open and close the positioning pin 9. An adjustable threaded rod 19 is provided, and the lifting seat 14 can be moved and positioned by the stop block 20 on the threaded rod 19, so as to achieve the positioning of the opening degree of the positioning pin 9.

[0035] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
