ABSTRACT:
A rapid acting adjustable clamp includes a precision ground dovetail track which carries a cam actuated locking assembly along a bridge portion of the clamp to provide quick initial setup, secure workpiece retention, quick release, and highly repeatable subsequent re-actuation of the clamp. The resulting positive acting clamp is particularly advantageous for use in precision grinding, milling, and electron discharge machining operations where a number of similar workpieces are to be machined. The dovetail joint provides rapid sliding adjustment along a first workpiece engaging axis while a single threadedly adjustable screw provides rapid setup along an orthogonal workpiece engaging axis. The combination of these quick adjustments with the single lever cam locking actuation greatly reduces the number of repetitive operator manipulations required in its use, resulting in significantly improved clamping action and in increased productivity by its use.
