Abstract
A fluid-actuated workholding apparatus that includes a base member that has a longitudinally extending slot and a fixed jaw attached thereto. The apparatus further includes first and second movable jaw members that are operably supported on the base member for movement towards and away from the fixed jaw member along the longitudinally extending slot. A clamping assembly is operably supported within the longitudinally extending slot and serves to define a fluid receiving cavity for receiving a pressurized fluid therein. The clamping assembly communicates with the first and second movable jaw members such that when a predetermined amount of pressurized fluid is admitted to the receiving cavity, the first and second movable jaw members are caused to move away from the fixed jaw member. The clamping assembly also includes means for biasing the first and second movable jaw members towards the fixed jaw member when the pressurized fluid is removed from the receiving cavity to enable a first workpiece to be clamped between the first movable jaw member and the fixed jaw member under a compressive force and a second workpiece to be clamped between the second movable jaw member and the fixe…
