Description

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillating motion). Hydraulic cylinders are broadly classified into three types: piston cylinders, plunger cylinders, and oscillating cylinders. Piston cylinders and plunger cylinders achieve reciprocating linear motion, outputting speed and thrust, while oscillating cylinders achieve reciprocating oscillation, outputting angular velocity (speed) and torque. The main components of a hydraulic cylinder include the cylinder head, cylinder cover, cylinder barrel, piston, piston rod, guide sleeve, seals, and tie rod. The cylinder head is a crucial component of the hydraulic cylinder; it is typically connected to the piston rod and located at the front of the cylinder.

Therefore, different positioning and clamping devices need to be changed during the machining of different models of hydraulic cylinder heads, which reduces the machining efficiency. In addition, the various specifications of positioning and clamping devices are used to manufacture various models of hydraulic cylinder heads, which greatly increases the manufacturing cost.

[0044] like Figure 6 The diagram shown is a usage state diagram of the irregular part processing positioning and clamping device in this utility model.
