Especially in recent years and microelectronics, computer technology combined, so that the hydraulic technology has entered a new stage of development. At present, has been widely used in various industrial fields. Due to the development of microelectronics, computer technology in recent years, hydraulic components manufacturing technology to further improve, so that the hydraulic technology not only plays an important role in as a basic form of traditional and good static and dynamic performance, has become an important means of control. This paper first introduces the working principle, hydraulic system, and explains the characteristics and advantages of hydraulic clamp. Then analysis the workpiece machining process and machining characteristics, determine the fixture function, analysis of positioning and clamping the workpiece requirements, determine the positioning and clamping scheme; analysis of positioning and clamping the workpiece requirements, determine the positioning and clamping scheme; determine the fixture structure, determine the clamping mechanism (hydraulic clamping) scheme; analysis of the hydraulic system of the working process, the design schematic diagram of hydraulic system; design; design and calculation of main parameters of hydraulic system, namely the pump working pressure, hydraulic flow, motor power, relief valve, sequence valve set pressure value.
