After the wheel is dynamically balanced, the position where the balance weight needs to be pasted is determined, and the sliding base 11 moves the first extrusion piece 14 and the second extrusion piece 15 to the inside of the wheel. The first cylinder 16 and the second cylinder 17 are controlled by the air control component 18 to operate the first cylinder 16 and the second cylinder 17 to drive the first mounting frame 12 and the second mounting frame 13 to move. After the first extrusion piece 14 and the second extrusion piece 15 are moved to the position where the balance weight needs to be pasted, the first cylinder 16 and the second cylinder 17 stop operating and lock the first mounting frame 12 and the second mounting frame 13. The extrusion components on the pressing piece 14 and the second extrusion piece 15 extrude and stick the balancing weight to the inner wall of the wheel.
