摘要： A pallet changer for a machine tool is provided wherein a pallet clamper for guiding a work pallet during transfer movements onto and away from a rotary table of the machine tool is supported at its center portion and vertically movable by a hydraulic cylinder. This cylinder moves the clamper up to unclamp the pallet from the rotary table prior to the transfer movements and moves the clamper down to clamp the pallet on the rotary table upon completion of the transfer movement onto the rotary table. Auxiliary hydraulic cylinders are further provided at either end portions in a pallet transfer direction of the clamper and between the rotary table and the clamper for auxiliarily supporting the clamper while the pallet is unclamped, so that the clamper can be prevented from being deformed due to the weight of a mass of the pallet and workpiece supported only by the clamper during such time.
