Two-sided clamp for cylinder cover milling machine

A two-sided clamp for a cylinder cover milling machine comprises a clamp body, positioning plates arranged on the clamp body and positioning pins. The two-sided clamp for the cylinder cover milling machine is characterized in that the clamp body comprises a bottom plate parallel to the horizontal plane, a vertical plate perpendicular to the bottom plate and supporting plates, U-shaped grooves are formed in the bottom plate, and the top of the vertical plate is provided with lifting eye bolts; a pressing plate is adjustably limited to the outer end of a double-end bolt through a nut, and the double-end bolt is sleeved with a compression spring in a connecting mode; the first positioning plates are symmetrically arranged at the positions at the same height with the double-end bolt, the second positioning plates are symmetrically arranged on the lower portion of the cylindrical backing pin, and two third positioning plates are symmetrically arranged on the cylinder cover fixing side of the bottom plate; the cylindrical positioning pins or rhombic positioning pins are arranged on the vertical plate. The two-sided clamp for the cylinder cover milling machine fundamentally solves the problems that an existing milling machine is low in machining efficiency, high in machining cost and the like. The two-sided clamp for the cylinder cover milling machine is ingenious in structural design, and has the advantages of being simple in structure, convenient and rapid to operate and low in equipment investment, lowering the labor intensity of operators and the like.
