[0033] When the wheel hub is clamped and fixed, the hydraulic rod 4 is started, so that the output end of the hydraulic rod 4 drives the accommodating shell 5 to move. When the accommodating shell 5 moves to a suitable position, the electric guide rail 2 is started, so that the electric guide rail 2 drives the moving frame 3 to move, and then the moving frame 3 drives the hydraulic rod 4 to move, and then the hydraulic rod 4 drives the brush 12 to move through the accommodating shell 5, so that the brush 12 cleans the surface of the wheel hub. When the brush 12 contacts the surface of the wheel hub, the wheel hub presses the brush 12, so that the brush 12 presses the loading plate 11, and then the loading plate 11 is pressed and presses the connecting plate 10, and then the connecting plate 10 drives the sliding plate 9 to slide inside the cavity 6 when it moves, so that the sliding plate 9 presses the telescopic column 7 when it moves, and at the same time compresses the spring 18, and under the action of the spring 18 returning, the brush 12 and the surface of the wheel hub are more closely fitted, so that the brush 12 can clean the surface of the wheel hub more thoroughly.
