一种绿色化的气动-液压-机械复合传动夹具

摘要

介绍一种绿色化的气动-液压-机械复合传动夹具.该机构采用气动驱动、铰杆增力机构及密封液体面积效应增力机构,具有耗能低、不污染环境的优点,同时具有液压夹具的夹紧力大、易于空间布置的优点.此外,由于采用铰杆增力机构,夹紧元件的速度由快到慢最终达到最大夹紧力,缩短夹紧时间.%A kind of pneumatic - hydraulic - mechanical composite transmission fixture was introduced. In this fixture, pneumatic drive, toggle force amplifier institution and area effect increased force agencies of the sealed liquid were adopted. The fixture has the advantages, such as low consumption, no pollution, big clamping force and easy space layout. In addition, because of adopting toggle force amplifier institution, the clamping speed of the components changes from fast to slow and the maximum of the clamping force is reached finally, so the clamping time is shortened.
