The multi-action hydraulic actuator comprises a rail, a first sliding block and a second sliding block are arranged on the rail in a sliding mode, the first sliding block and the second sliding block are connected in the axial direction through a movable oil cylinder, a plurality of positioning holes are formed in the upper end of a sliding rail in the axial direction, and plug pin oil cylinders are installed on the second sliding block and the first sliding block. When one of the first sliding block and the second sliding block is in the unlocking state and the other one is in the locking state, the front end of the plug pin oil cylinder stretches into the positioning hole to enable the first sliding block or the second sliding block to be in the locking state, and the front end of the plug pin oil cylinder is separated from the positioning hole to enable the first sliding block or the second sliding block to be in the unlocking state. The moving oil cylinder pulls the sliding block in the unlocking state to move towards the sliding block in the locking state. By means of the mode, the multi-action hydraulic actuator can move front and back through stepping control, the moving precision is high, and positioning is accurate.
本发明公开了一种多动作液压执行器,包括轨道,轨道上滑动设置有滑块一和滑块二,滑块一和滑块二在轴向上通过移动油缸相连接,滑轨上端沿轴向开设有多个定位孔,滑块二和滑块一上安装有插销油缸,插销油缸前端伸入定位孔使滑块一或滑块二处于锁定状态,插销油缸前端脱离定位孔使滑块一或滑块二处于解锁状态,当所述滑块一和滑块二中一个为解锁状态,一个为锁定状态时,移动油缸拉动处于解锁状态的滑块向处于锁定状态的滑块移动。通过上述方式,本发明多动作液压执行器,能够通过步进控制实现前后移动,移动精度高,定位准确。
