ABSTRACT:
The present invention relates to a modular, multiple actuator assembly for providing a clamping force on a machine tool vise or other clamp which includes a plurality of parallel operating pistons and cylinders providing an additive force to a movable clamp jaw. The modular assembly can be installed easily in existing vises as well as in new vises. The modular actuator has a number of individual piston-cylinder assemblies acting to be additive in force so a high clamping force can be obtained using standard air pressure supplies found in machine tool shops and factories.
