ABSTRACT:
An apparatus for applying a force to a workpiece as required in welding or clamping. The apparatus applies a force to the workpiece through a direct clamping action or through link enhanced scissor type action that increases the mechanical force supplied by a fluid driven cylinder. The fluid driven cylinder has piston rods at both ends of an elongated external housing. The fluid driven cylinder is supported at one end by an attachment to the end of one piston rod and is supported at the other end by an attachment to the external housing. A plurality of pistons permit the piston rods to move relative to one another and also relative to the external housing. The entire fluid driven cylinder can rotate and translate.
