【正文】 1) Machining the workpiece loading and unloading, especially in the automatic lathe, bination machine tool use is more mon. (2) In the assembly operations are widely used in the electronics industry, it can be used to assemble printed circuit boards, in the machinery industry It can be used to assemble parts and ponents. (3) The working conditions may be poor, monotonous, repetitive easy to subfatigue working environment to replace human labor. (4) May be in dangerous situations, such as military goods handling, dangerous goods and hazardous materials removal and so on.. (5) Universe and ocean development. (6), military engineering and biomedical research and testing. Help mechanical hands: also known as the balancer, balance suspended, laborsaving spreader, manual Transfer machine is a kind of weightlessness of manual load system, a novel, timesaving technology for material handling operations booster equipment, belonging to kinds of nonstandard design of series products. Customer application needs, creating customized cases. Manual operation of a simulation of the automatic machinery, it can be a fixed program draws ﹑ handling objects or perform household tools to acplish certain specific actions. Application of robot can replace the people engaged in monotonous ﹑ repetitive or heavy manual labor, the mechanization and automation of production, instead of people in hazardous environments manual operation, improving working conditions and ensure personal safety. The late 20th century, 40, the United States atomic energy experiments, the first use of radioactive material handling robot, human robot in a safe room to manipulate various operations and experimentation. 50 years later, manipulator and gradually extended to industrial production sector, for the temperatures, polluted areas, and loading and unloading to take place the work piece material, but also as an auxiliary device in automatic machine tools, machine tools, automatic production lines and processing center applications, the pletion of the upper and lower material, or From the library take place knife knife and so on according to fixed procedures for the replacement operation. Robot body mainly by the hand and sports institutions. Agencies with the use of hands and operation of objects of different occasions, often there are clamping ﹑ support and adsorption type of care. Movement ans are generally hydraulic pneumatic ﹑ ﹑ electrical device drivers. Manipulator can be achieved independently retractable ﹑ rotation and lifting movements, generally 2 to 3 degrees of freedom. Robots are widely used in metallurgical industry, machinery manufacture, light industry and atomic energy sectors. Can mimic some of the staff and arm motor function, a fixd procedure for the capture, handling objects or operating tools, automatic operation device. It can replace human labor in order to achieve the production of heavy mechanization and automation that can operate in hazardous environments to protect the personal safety, which is widely used in machinery manufacturing, metallurgy, electronics, light industry and nuclear power sectors. Mechanical hand tools or other equipment commonly used for additional devices, such as the automatic machines or automatic production line handling and transmission of the workpiece, the replacement of cutting tools in machining centers, etc. generally do not have a separate control device. Some operating devices require direct manipulation by humans。 in order to increase the output power is bound to the structure of the entire pneumatic system size increased. With pneumatic drive and pare with other energy sources drive has the following advantages: Air inexhaustible, used later discharged into the atmosphere, without recycling and disposal, do not pollute the environment. Accidental or a small amount of leakage would not be a serious impact on production. Viscosity of air is small, the pipeline pressure loss also is very small, easy longdistance transport. The lower working pressure of pressed air, pneumatic ponents and therefore the material and manufacturing accuracy requirements can be lowered. In general, reciprocating thrust in 1 to 2 tons pneumatic economy is better. Compar
