ABSTRACT:
A machine tool is provided with a double actuation hydraulic cylinder incorporated into a pallet clamp member, which is vertically movable for clamping and unclamping a work pallet onto and releasing it from a work table of the machine tool. The cylinder, in an extension operation, outwardly extends a first hollow rod and further extends a second rod telescopically from the first rod so as to present a first engaging member secured to the outer end of the second rod under a second engaging member of a work pallet on a pallet support. The pallet clamp member, when upwardly moved, establishes engagement of the first engaging member with the second engaging member, so that the subsequent retraction operation of the cylinder causes the work pallet to be transferred from the pallet support onto the work table.
