Abstract: the hydraulic system has wide adaptability, good process control performance, fast response, large output force (or torque) etc, and widely adopted in the modular machine tool.
Hydraulic transmission technology is one of the fastest growing technologies in machinery and equipment, especially in recent years and microelectronics, computer technology, hydraulic technology has entered a new stage of development, machine, electricity, liquid, gas integration is the development direction of mechanical equipment. In nc machining of mechanical equipment has been widely quoted hydraulic technology. As the numerical control technology application specialized students learn the design of the hydraulic system, familiar with the working principle of the hydraulic system of the method, to grasp the function and type selection of ponents and hydraulic system maintenance and repair is necessary.
Combination machine tools with its unique advantages in the mechanical design occupies an important position; It is based ponents, according to the workpiece machining needs, with a small amount of ponents of a machine tool. It has the characteristics of low cost, high efficiency.
This thesis mainly expounds the design of hydr
