Provided is a gripper comprising an actuator installed to be lifted and lowered by an operating cylinder, and a collet of a cylindrical shape divided into multiple pieces, installed to surround the actuator. While being in an insertion part of a workpiece, the collet is spread out and the diameter thereof widens as the actuator is lowered, such that the gripper grips the workpiece. The collet includes a pressurized protrusion part at an inner lower part, the top surface of which slants downwards and protrudes inwards. The actuator includes a slant pressurizing part which has a slant shape and pressurizes the pressurized protrusion part to open the collet when the actuator is lowered, and a vertical support part which has a vertical shape and becomes in close contact with the pressurized protrusion part to support the collet when the actuator is completely lowered. According to the present invention, since gripping is stably supported and maintained, the safety is improved and energy consumption may be reduced.

    본 발명은 그리퍼장치에 관한 것으로서, 작동자가 작동실린더에 의해 승강 가능하도록 설치되고, 상기 작동자의 외부에는 원통형을 다수개로 분할한 형태의 콜릿이 설치되어, 상기 콜릿이 작업대상물의 삽입부로 진입된 상태에서 상기 작동자의 하강에 따라 상기 콜릿이 벌어져 직경이 확대됨으로써 작업대상물을 그리핑하는 그리퍼장치에 있어서, 상기 콜릿의 내부 하측에는 상면이 하향 경사지면서 내측으로 돌출된 피압돌부가 형성되고, 상기 작동자에는 하강시 상기 피압돌부을 가압하여 콜릿을 벌려주는 경사진 형태의 경사가압부와, 하강의 완료시 상기 피압돌부와 밀착되어 벌려진 콜릿을 지지하는 수직한 형태의 수직지지부가 형성되는 특징으로 이루어진다. 이러한 본 발명에 따르면, 그리핑의 안정적인 지지상태가 유지되어 안전성을 향상시키고 에너지소모 또한 절감할 수 있는 장점이 있다.
