[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-5As shown, a motorcycle wheel hub processing fixture includes a mounting ring 3, a fixing seat 1 connected to the outer periphery of the mounting ring 3, and a mounting hole 2 provided on the fixing seat 1. The fixing seat 1 is fixed through the mounting hole 2, thereby installing the device in the required position.

[0021] A rotating ring 4 is provided inside the mounting ring 3. Both the upper and lower sections of the rotating ring 4 are connected to rotating shafts 5. The other end of the rotating shaft 5 is rotatably connected to the mounting ring 3. Specifically, a bearing is installed on the inner circumference of the mounting ring 3, and the end of the rotating shaft 5 away from the rotating ring 4 is installed inside the bearing, allowing the rotating ring 4 to rotate within the mounting ring 3. A limiting mechanism 25 is provided on the mounting ring 3 to restrict the position of the rotating ring 4.

[0022] like Figure 2 , Figure 3 As shown, the limiting mechanism 25 includes a mounting sleeve 14 installed on the outer periphery of the mounting ring 3. A pin 15 passes through the mounting sleeve 14, and a limiting ring 16 is installed on the portion of the pin 15 inside the mounting sleeve 14. A spring 17 is sleeved on the pin 15, located between the limiting ring 16 and the outer wall of the mounting sleeve 14. A limiting hole 26 is opened on the outer periphery of the rotating ring 4 to cooperate with the pin 15. Under the action of the spring 17, the limiting ring 16 can drive the pin 15 to be inserted into the limiting hole 26, thereby limiting the position of the rotating ring 4. When it is necessary to rotate the rotating ring 4, the pin 15 is pulled outward, causing the pin 15 to disengage from the limiting hole 26, thus releasing the limitation on the rotating ring 4 and allowing the rotating ring 4 to rotate.

[0023] The end of the pin 15 near the limiting hole 26 is tapered and has a small diameter, making it easy to insert into the limiting hole 26.

[0024] A clamp is installed inside the rotating ring 4. The clamp includes a clamp 6 and two clamps 7. The clamp 6 is located at the lower part of the inner circumference of the rotating ring 4. The included angle between the clamp 6 and the two clamps 7 is the same, and the included angle between the clamp 6 and the clamps 7 is 120°.

[0025] like Figure 4As shown, clamp 6 includes a mounting box 18 and a clamping block 22. The mounting box 18 is installed on the inner circumference of the rotating ring 4. An adjusting nut 19 is rotatably mounted on the upper part of the mounting box 18. A limit groove is formed at the lower part of the adjusting nut 19. A guide rail is installed on the top of the mounting box 18. The adjusting nut 19 is installed on the top of the mounting box 18 through the cooperation of the limit groove and the guide rail. The cooperation of the limit groove and the guide rail can restrict the adjusting nut 19 from moving axially or radially, but does not restrict the adjusting nut 19 from rotating about its axis. A connecting block 21 is connected to the lower part of the clamping block 22. An adjusting screw 20 is rotatably mounted on the lower part of the connecting block 21. The adjusting screw 20 passes through the adjusting nut 19 and is threadedly connected to the adjusting nut 19. By rotating the adjusting nut 19, the adjusting screw 20 is driven to rise and fall, thereby driving the clamping block 22 to rise and fall, thus adjusting the height of the clamping block 22, which can clamp motorcycle wheel hubs of different diameters.

[0026] A guide rod 23 is connected to the lower part of the clamping block 22. The guide rod 23 passes through the top of the mounting box 18 and is used to guide the lifting and lowering of the clamping block 22 to prevent the clamping block 22 from deflecting.

[0027] The second clamp 7 includes a mounting base 8 and a second clamping block 10. The mounting base 8 is installed on the inner circumference of the rotating ring 4. The second clamping block 10 is internally connected to a connecting rod 9, the other end of which extends into the mounting base 8. The mounting base 8 has an oblong hole 11. A fixing screw 12 is connected to the connecting rod 9, passing through the oblong hole 11. The portion of the fixing screw 12 that extends out of the oblong hole 11 is threadedly connected to a fixing nut 13. After the wheel hub is placed on the first clamp 6, the fixing nut 13 is loosened, the position of the second clamping block 10 is adjusted so that the second clamping block 10 abuts against the outer circumference of the wheel hub, and then the fixing nut 13 is tightened to fix the position of the second clamping block 10, thereby completing the clamping and fixing of the wheel hub.

[0028] like Figure 5 As shown, several anti-slip strips 24 are provided on the inner side of clamping block 1 22 and clamping block 2 10. The anti-slip strips 24 are inclined and made of rubber. The anti-slip strips 24 can increase the friction between the anti-slip strips and the wheel hub, making the clamping more secure, and at the same time protect the wheel hub and prevent the wheel hub from being damaged due to excessive clamping force.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
