[0034] Each abutment assembly includes a built-in groove 24 provided on the side wall of the rotating seat 23, a cylinder 1 is fixed on the inner wall of the built-in groove 24, an arc-shaped abutment block 25 is fixed to the end of the telescopic end of the cylinder 1, when the wheel hub is placed on the upper end surface of the rotating base 2, the telescopic end of the cylinder 1 extends, pushing the arc-shaped abutment block 25 close to the inner wall of the wheel hub, thereby clamping and fixing the wheel hub to prevent the wheel hub from shaking during polishing operation and affecting the use effect.

[0035] Each pair of scraping components includes a rectangular groove 26 symmetrically opened on the outer side wall of the rotating seat 23, a moving plate 27 is slidably arranged in the rectangular groove 26, and a cylinder 2 for driving the moving plate 27 to move is fixedly arranged in each rectangular groove 26. A scraping layer is fixed at the end of the moving plate 27. One pair of scraping components is located at the upper section of the rotating seat 23, and the other pair of scraping components is located at the lower section of the rotating seat 23. The thickness of the two scraping layers used in each pair of scraping components is different and is in an increasing state, so as to avoid the scraping layer from generating a large friction when contacting the inner wall of the wheel hub, causing the moving plate to move. 27 is deformed. When it is necessary to grind and polish the inner wall of the wheel hub, each arc-shaped resistance block 25 moves into the corresponding built-in groove 24, and then each cylinder 2 drives the corresponding movable plate 27 to move outward until each scraping layer contacts the inner wall of the wheel hub, and then the two clamping blocks 33 clamp and fix the outer wall of the wheel hub, and then each locking bolt 30 is unscrewed, and then the rotating base 2 drives the rotating seat 23 to rotate, thereby driving each movable plate 27 and the scraping layer to rotate, and the inner wall of the wheel hub is grinded and polished.

[0036] The receiving assembly includes a rotating ring 28 rotatably sleeved on the outer wall of the rotating base 2, a receiving ring 29 is fixedly sleeved on the outer wall of the rotating base 2, and a plurality of rotating balls are rotatably provided on the upper and lower end surfaces of the receiving ring 29, and a rotating slide groove used for matching with the receiving ring 29 is provided on the inner wall of the rotating ring 28, and a plurality of locking bolts 30 are threadedly penetrated on the outer wall of the rotating ring 28, and a plurality of threaded holes 31 used for matching with the locking bolts 30 are provided on the outer wall of the receiving ring 29. When the locking bolts 30 are tightened and installed on the outer wall of the rotating ring 28, the receiving ring 29 is locked. It is connected to the rotating circle 28 under the action of each locking bolt 30 to form a whole. At this time, the rotating circle 28 cannot rotate, so that the rotating base 2 can drive the wheel hub to rotate together through the arc-shaped interference block 25. When the locking bolt 30 is unscrewed from the rotating circle 28, the rotating circle 28 can rotate freely at this time. Therefore, when the two clamping blocks 33 clamp the wheel hub, the rotating base 2 drives the receiving circle 29 to rotate, and the wheel hub and the rotating circle 28 that supports the weight of the wheel hub are different, so that the rotating movable plate 27 and the scraping layer can grind and polish the inner wall of the wheel hub.

[0039] When the small grinding roller 9 has finished grinding the retaining ring at the upper end of the wheel hub, the large grinding roller 6 has also finished grinding the outer side wall of the lower section of the rim. At this time, the drive box drives the driving gear to rotate, thereby driving the left screw 13 and the right screw 16 to rotate together. During this process, the left slider 14 moves the left connecting block 15 and the small mounting seat 8 downward, and the right slider 17 moves the right connecting block 18 and the large mounting seat 5 upward. The movement rate of the left slider 14 is greater than that of the right slider 17. When the small mounting seat 8 moves and fits the outer side wall of the retaining ring at the lower end with the small grinding roller 9, the large mounting seat 5 moves and fits the outer side wall of the upper section of the rim with the large grinding roller 6, and then grinds the outer side wall of the lower end retaining ring and the outer side wall of the upper section of the rim respectively, which is easy to operate.
