, air balance the hanging, etc.) Third, railtype transport system (hanging rail, light rail, single girder cranes, doublebeam crane) Four, industrial machinery, application of hand Manipulator in the mechanization and automation of the production process developed a new type of device. In recent years, as electronic technology, especially puter extensive use of machine hand development and production of hightech fields has bee a rapidly developed a new technology, which further promoted the development of machine hand, allowing machine hand to better achieved with the bination of mechanization and automation. Although the machine hand is not as flexible as staff, but it has to the continuous duplication of work and labor, I do not know fatigue, not afraid of danger, the power snatch weight characteristics when pared with manual large, therefore, mechanical hand has been applied widely, for example: a) Machining the work piece loading and unloading, especially in the automatic lathe, bination machine tool use is more mon. b) 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. c) The working conditions may be poor, monotonous, repetitive easy to subfatigue working 濟(jì)南大學(xué)畢業(yè)設(shè)計(jì)外文資料翻譯 4 environment to replace human labor. d) May be in dangerous situations, such as military goods handling, dangerous goods and hazardous material removal and so on. e) Universe and ocean development. f) Military engineering and biomedical research and testing. Help mechanical hand: all know 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 applications needs, creating customized cases. Manual operation of a simulation of the automatic machinery, it can be a fixed program draws, handling objections or perform household tools to acplish certain specific actions. Application of machine hand 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 safely. The late 20th century,40, the United Stated atomic energy experiment, the first use of radioactive material handling machine hand, human machine hand in a safe room to 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. Machine hand body mainly by the hand and sport 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 indecently retractable, rotation and lifting movements, generally 2 to 3 degrees of freedom. Machine hands are widely used in metallurgical industry, machinery manufacture, light industry and atomic energy sectors. It can replace human labor in order to achieve the production of heavy mechanization and automation that can operate in hazardous environment 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 monly used for additional devices, such as the automatic machines or automatic production line handling and transmission of the work piece, the replacement of cutting tools in machining centers ,etc. generally do not have a separate control device.
