The knob handle 20 is rotated, and the knob handle 20 drives the screw rod 19 to rotate in the slide groove 17. The screw rod 19 drives the slider 18 to slide in the slide groove 17 through the thread, and the slider 18 drives the limit block 22 to rotate on the mounting plate 10. 0, place the wheel hub to be polished on the mounting plate 10, turn the knob handle 20 to drive the screw rod 19 to drive the slider 18, until the slider 18 drives the limit block 22 to abut against the inner wall of the wheel hub to be polished, and after adjusting the position of the limit block 22 on the mounting plate 10 according to the size of the wheel hub to be polished, screw the fixing bolt 21 back to its original position, and the fixing bolt 21 abuts against the mounting plate 10 again, and the friction between the fixing bolt 21 and the mounting plate 10 limits the rotation of the knob handle 20, so that the screw rod 19 no longer rotates. The movable slider 18 is moved to fix the position of the limit block 22 on the mounting plate 10. When it is necessary to process a wheel hub to be polished of a different size, the above steps are repeated until the limit block 22 abuts against the inner wall of the new wheel hub to be polished again. Then, the movable rod 16 is pulled to drive the sleeve 15 to drive the pressure rod 13, and the pressure rod 13 drives the rubber block 14 to press one side of the rubber block 14 tightly against the outer side of the wheel hub to be polished.

At this time, the first motor 2 is stopped, and the movable disk 5 drives the clamping assembly 6 to drive the wheel hub to be polished to stop at the fixed column 7, and the second motor 8 is started, and the output end of the second motor 8 rotates to drive the polishing wheel 9 to rotate to polish the wheel hub to be polished, and then the third motor 11 is started, and the output end of the third motor 11 rotates to drive the installation disk 10 to drive the wheel hub to be polished to rotate, and the polishing wheel 9 polishes the rotating wheel hub to be polished After the wheel hub to be polished rotates, the polishing wheel 9 can fully polish the top of the wheel hub to be polished. During the polishing operation of the polishing wheel 9, the staff will install the new wheel hub to be polished into the other empty clamping assembly 6. After the polishing of the current wheel hub to be polished is completed, the first motor 2 will continue to be started. The output end of the first motor 2 drives the driving gear 3 to drive the gear ring 4 to drive the movable disk 5 to drive the clamping assembly 6 to rotate the polished wheel hub away from the fixed column 7, and rotate the new wheel hub to be polished installed on the other empty clamping assembly 6 to the fixed column 7 for polishing. Then, the polished wheel hub is removed, and the new wheel hub to be polished is installed. The operation is repeated, thereby saving the time for installing and disassembling the wheel hub to be polished and improving work efficiency.
