Abstract

The invention relates to a hydraulic catch cam, which belongs to a mechanical hand. The mechanical hand comprises solenoid valves (1), (2), one-way back valves (3), (4), a piston (5), an inner cylinder body (6), an outer cylinder body (7), a hydraulic oil tank (8), a seal ring (9), an upper connecting link (10), a lower connecting link (11), a gripping claw (12) and a connecting axle pin (13). The invention has the advantages that the structure is simple, the control is automatic, the stretching is convenient and flexible, and the grabbing action, the releasing action and the reset action are finished by utilizing dead weight. The invention can be manufactured into specifications and models with different sizes to be suitable for different purposes, the invention not only can be manufactured the hand of a mobile robot, but also can be manufactured the fittings of a field working machinery which is used for substances in traveling, craning, fishing, deep pit grabbing, deep well, deep sea and a floating substance and a blocking substance in front of a fishing and grabbing cement factory and a hydropower station trash rack.

Description

Technical field: [0001] The invention relates to a manipulator. Background technique: [0002] One of the existing manipulators is to manually control the movement of the gripper, which has a low degree of automation and a small scope of application; the other is to rely on hydraulic pressure to laterally push the gripper to clamp, which consumes energy, has a complex structure, and has a small clamping force. reliable. Invention content: [0003] The present invention aims to overcome the disadvantages of the background technology, and provides a hydraulic gripper, which automatically controls the expansion and contraction of the hydraulic cylinder arm to control the gripping and lowering of objects by the gripper. The present invention consists of solenoid valves (1), (2), one-way check valves (3), (4), piston (5), inner cylinder (6), outer cylinder (7), hydraulic oil tank (8) , sealing ring (9), upper connecting rod (10), lower connecting rod (11), gripper (12), conne...
