<p>A clamping device for clamping a work piece to be machined by a machine tool on a base surface of a table of the machine tool or a work pallet for fixing a work piece, comprises at least a clamp main body (1), a reaction support (4) provided at the rear portion of the clamp main body, an input member (8) disposed in front of the reaction support (4) on the clamp main body (1) with a gap therebetween, an output member (5) arranged in front of the input member and having an output portion for clamping the work piece at the front end, a guide mechanism for slidably guiding the output member in a longitudinal direction directed back and forth, a driving mechanism for driving the input member toward the clamp main body, and a wedge type converting mechanism for converting a driving force supplied to the input member from the driving mechanism into a clamping force for driving the output member. During clamping drive or operation, the output member does not move vertically, thereby the work piece is free from damage and the machining accuracy is improved. <IMAGE></p> |
