First, the axle is placed on the two supporting mechanisms 108, and then the fixing mechanism is controlled to move horizontally to clamp the axle. Then, the hydraulic cylinder 110 is started, and the hydraulic cylinder 110 controls the lifting and lowering of the driving housing 111 to ensure that the driving housing 111 can contact the axle. Then, the driving motor 112 is started, so that the driving motor 112 controls the rotation of the rotating rod 113 through the transmission belt. Under the joint action of the rotating rod 113 and the supporting mechanism 108, the axle is rotated, which is convenient for axle processing.

[0028] Among them, the fixing plate is hingedly provided with a fixed inner plate 116, a convex block 117 is provided below the side fixing plate 115, and a thread groove 118 is provided in the convex block 117.
