[0018] 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.

[0019] like Figures 1-4As shown, a wheel hub polishing device includes a base 9, on which a turntable 1 is rotatably mounted. A gear ring 12 is mounted on the bottom of the turntable 1, and teeth are arranged on the inner circumference of the gear ring 12. A drive motor 10 is mounted on the side of the base 9, and the drive motor 10 is driven and connected to a drive gear 11, which meshes with the gear ring 12. Several turntables 2 are mounted on the turntable 1, and the turntables 2 are evenly distributed on the turntable 1. A clamp 3 for holding the wheel hub is provided on the turntable 2. It also includes two mounting brackets 4, on which a lead screw motor 5 is mounted. The lead screw motor 5 is driven and connected to a lead screw 6, which is vertically arranged. A lifting plate 7 is mounted on the lead screw 6, and a polishing motor 8 is mounted on the lifting plate 7. The drive shaft of the polishing motor 8 passes through the lifting plate 7 and is connected to a polishing disc 15.

[0020] Drive motor 10 drives drive gear 11 to rotate. Drive gear 11, through its engagement with gear ring 12, drives turntable 1 to rotate, moving turntable 2 below lifting plate 7. Lead screw motor 5 drives lead screw 6 to rotate, causing lifting plate 7 to descend, bringing polishing disc 15 into contact with the upper surface of the hub on turntable 2. Polishing motor 8 is activated to rotate polishing disc 15, thereby polishing the upper surface of the hub. The polishing discs 15 mounted on the two polishing motors 8 have different grit sizes, performing rough polishing and fine polishing respectively. Step-by-step polishing ensures polishing effect and reduces the processing time of the hub under each polishing disc 15, reducing waiting time and accelerating overall processing efficiency. The remaining turntables 2, not located below lifting plate 7, can be used for hub disassembly and installation, preparing for subsequent processing and also improving overall production efficiency.

[0021] Turntable 1 has several mounting bases 13 installed inside, and drive motor 2 14 is installed inside the mounting bases 13. The drive shaft of drive motor 2 14 passes through turntable 1 and is connected to turntable 2 2. The drive motor 2 14 drives turntable 2 2 to rotate, thereby driving the hub to rotate, which increases the friction between the hub and polishing disc 15 and speeds up the polishing process.

[0022] Furthermore, the clamp 3 includes a fixed clamping component and a movable clamping component. The fixed clamping component includes a fixed block 20 mounted on the upper part of the turntable 2, and a clamping plate 21 connected to the fixed block 20. The movable clamping component includes a clamping plate 27. A groove 22 is formed on the upper part of the turntable 2, and the groove 22 is arranged radially along the turntable 2. A lead screw motor 24 is arranged in the groove 22, and the lead screw motor 24 drives and connects to a lead screw 23. A lead screw slider 25 is arranged on the lead screw slider 23, and a mounting arm 26 is connected to the lead screw slider 25. The clamping plate 27 is connected to the mounting arm 26.

[0023] The second lead screw motor 24 drives the second lead screw 23 to rotate, thereby controlling the movement of the lead screw slider 25. When clamping the wheel hub, the second clamping plate 27 moves towards the first clamping plate 21. The first clamping plate 21 and the second clamping plate 27 clamp and fix the wheel hub from both sides of the outer periphery. Increasing the size of the first clamping plate 21 increases the contact surface with the wheel hub, thereby improving the clamping tightness.

[0024] Both clamping plate 21 and clamping plate 27 are arc-shaped, matching the outer circumference of the wheel hub to more firmly clamp the hub. The arc-shaped recesses of clamping plate 21 and clamping plate 27 are positioned opposite each other.

[0025] Furthermore, a suction port 16 is provided on the side of the mounting frame 4 closest to the turntable 1, and a fan 18 is provided on the side of the mounting frame 4 away from the turntable 1. A suction pipe 17 is connected to the fan 18, and the other end of the suction pipe 17 is connected to the suction port 16. A filter element 19 is installed inside the suction port 16. The upper and lower side walls of the suction port 16 are inclined inward and downward. The filter element 19 includes a mounting frame 28, a filter cloth 29 is installed inside the mounting frame 28, and a side plate 30 is connected to the outside of the mounting frame 28. When the fan 18 is activated during the grinding process, some of the dust generated during the grinding process can be sucked into the suction port 16 and intercepted by the filter element 19. The shape of the mounting frame 28 is set according to the shape of the suction port 16, so that the bottom of the mounting frame 28 is inclined downward, and the intercepted dust can fall into this inclined area for collection. Before the intercepted dust falls from the filter element 19, the filter element 19 can be removed from the suction port 16 for cleaning.

[0026] The side plate 30 is larger than the opening size of the suction port 16. When the mounting frame 28 is inserted into the suction port 16, the side plate 30 can be stuck outside the suction port 16, thereby limiting the mounting frame 28 inserted into the suction port 16.

[0027] 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.
