The engine is applicable to both power generation devices and the entire machine including the power device (such as a gasoline engine in a car). The engine block of a car engine is mainly composed of parts such as a cylinder block, a cylinder liner, a cylinder head, and a cylinder gasket. During the high-pressure casting process of the cylinder liner of a car engine, a robot grabs the cylinder liner to the oiling table, and the aluminum liquid is transported from the holding furnace to the die-casting machine for casting. Therefore, cylinder liner feeding equipment is indispensable.
[0003] When loading the automobile engine cylinder liner onto the oiling table, a clamp is usually used. The automobile engine cylinder liner is placed on the oiling table through the cooperation of the clamp and the mechanical arm. When the automobile engine cylinder liner is clamped by the clamp, the clamping force will affect the loading of the automobile engine cylinder liner. If the clamping force is too small, the automobile engine cylinder liner may fall off during the clamping process, while if the clamping force is too large, the automobile engine cylinder liner may be deformed. Therefore, a clamp structure for clamping the automobile engine cylinder liner is proposed. Utility Model Content
