In this paper, the manipulator of the overall plan for the design, determine the coordinates of the mechanical hand type, freedom and manipulator of technical parameters. Were identified and the manipulator arm of the Rotary, the movements of arms, hand-hold in the structure and the replacement of devices such as hand and use PRO-E drawing of the maps which are lifter parts of loading manipulator, the structure of the connection assembly,the arms Assembly, the structure of the wrist, the structure of the hand, and other parts map. And briefly introduced the concept of industrial robots, robot on the composition and classification, manipulator freedom and coordinates the basic type of knowledge The demand of the subject is that the maniplator can move the shaft from one place to the other place.So it need to have the lifting and revolving function.Using a similar type of cylindrical coordinates. Has four degrees of freedom. The arm of the Rotary installations in the rack gear, hydraulic cylinders on the drive to achieve the movements of the arms . As the objects of their work for the aperture structure, the hand through the fingers stretching cylinder, and at promoting the realization of finger-hold at the start of the shaft and put aside. The pressure to replace the hand-can crawl different series of products. This has expanded the scope of the use of mechanical hand.Because the structure of the hydraulic system is simpleness,it is easy to mainten.Also it can lubricate itself.The arms lifting and the fingers constriction all use the hydraulic system. The practice proved that the industry manipulator may replace the manpower the strenuous labor, obviously reduces workers labor intensity, thus raises the economic efficiency. In the industrial production appears frequently unwieldy work piece transporting and long-term frequent, monotonous operation, uses the manipulator is very effective. Operation which carries on under the arduous condition, demonstrates its superiority, has the broad career development.
