공작기계로 기계가공하는 워크를 공작기계의 테이블과 워크를 고정하기 위한 워크 팔레트의 반면에 고정하는데에 적합한 클램핑 장치는 적어도, 클램프 본체와 그후부에 설치한 반력수부와 이 반력수부의 앞측에 있어서 클램프 본체상에 간격을 두고 배치된 입력부재와 이 입력부재의 앞측에 배치되고 또한 전단부에 워크를 클램프하기 위한 출력부를 가지는 출력부재와 이 출력부재를 전후방향만으로만 이동자재로 안내하는 안내기구와, 입력부재를 클램프 본체쪽으로 구동하기 위한 구동기구와 이 구동기구로부터 입력부재로 입력되는 구동력을 출력부재를 전방으로 이동시키는 클램프력으로 변환하는 경사면식 변화기구와를 구비하고 있다. 클램프 구동시나 클램프상태에 있어서 출력부재가 상하방향으로 움직이지 아니하기 때문에 워크가 손상되지 아니하고 가공정밀도가 향상한다. 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.
