description The invention relates to the field of machining, and particularly relates to an elastic expansion sleeve clamp. The clamp comprises a mandrel, wherein one end of the mandrel is fixedly connected with a flange plate, the flange plate is connected with a machine tool spigot through a bolt, and a ladder through hole is formed in the center of the mandrel; a piston is arranged in the ladder through hole, and the other end of the piston is connected with a bolt; one end of the piston far away from the bolt is provided with a mandril connected with a hydraulic cylinder of a machine tool, an elastic expansion sleeve sleeves the mandril, and a cavity is formed by the elastic expansion sleeve and the outer surface of the mandril and is filled with a liquid filler. The elastic expansion sleeve clamp provided by the invention is simple in structure and convenient to clamp, and does not vibrate in the course of processing after the clamping, the processing precision of parts can be improved, and the labor intensity of workers can be reduced.
