Piston rod will reset by the force of the sping, and the workpiece will be released, when the oil is cut off . The wrist is equipped with vanetype rotary cylinder. so, manipulator moves with the axis of rotation when driven by the vanes, completing its translocation movement .The arm is a combination of hydraulic cylinder and connecting rod ,and the piston rod is hinged on the arm.So the mechnical hand can achieve the pitching movement throught the piston rod’s linear motion .The design of the mechnical hand is a piece of auxiliary facility for automatic online processing of the R175-type diesel,which can feed, translocate and turn,what’s more, it can feed in a spherical space.
