Method of clamping a workpiece

摘要

A clamping device for frictional clamping of a workpiece which includes a clamp element adapted to frictionally clamp a workpiece and a mechanism for moving the clamp element which includes a shape memory alloy adapted to move the clamp element when the shape memory alloy is heated. The shape memory alloy moves the clamp element into a clamped state and/or unclamped state upon heating the shape memory alloy. The clamped element is preferably a super elastic alloy which is naturally oriented in a clamped position for a positive clamp and in an unclamped position for a non-positive clamp.
