ABSTRACT:
A workpiece clamping device with a movable clamp member actuated by a jack screw driven by a reversible electric motor through a worm meshing with a gear connected to the jack screw. To yieldably bias the clamp member into engagement with the workpiece, a spring is compressed by axial movement of the worm caused by rotating it after the clamp member is forced into engagement with the workpiece by the jack screw.
