In the present scheme, the clamping mechanism is redesigned, and an upper clamping seat is moved toward or away from a lower clamping seat by a telescopic mechanism. When the upper clamping seat is away from the lower clamping seat, the piston is placed on the lower clamping seat, and the upper and lower clamping seats are combined to form a clamp. The shifting mechanism moves the grinding mechanism to grind the end face of the piston, and the upper clamping seat is reset. A second telescopic mechanism moves a slide seat, and the slide seat moves relative to a limit frame. An elastic member causes the lower clamping seat to rotate relative to the slide seat, and synchronously causes the convex column to move along the upper inclined surface of the limit frame. The moving distance of the slide seat cooperates with the inclined surface of the limit frame to limit the rotation amplitude of the lower clamping seat. The lower clamping seat rotates to cause the piston in the cavity to slide down to complete the unloading, and the slide seat is reset. Under the action of the inclined surface of the limit frame, the lower clamping seat is reset, thereby improving efficiency and reducing costs.
