It can replace the heavy labor in order to achieve the production mechanization and automation, and can work in dangerous working environments to protect the personal safety, Therefore widely used in machine building, metallurgy, electronics, light industry and atomic energy sectors. This article is mainly of the pneumatic manipulator the overall design, and pneumatic design. This mechanism of manipulator includes cylinders and claws and connectors parts, it can move according to the due track on the movement of grabbing, carrying and unloading. The pneumatic part of the design is primarily to choose the right valves and design a reasonable pneumatic control loop, by controlling and regulating pressure, flow and direction of the compressed air to make it get the necessary strength, speed and changed the direction of movement in the prescribed procedure work.It can replace the heavy labor in order to achieve the production mechanization and automation, and can work in dangerous working environments to protect the personal safety, Therefore widely used in machine building, metallurgy, electronics, light industry and atomic .The principle, technical pare-maters, transmiting system and main parts structure of analysed.Keywords Mincing machine
