Manipulator Along with our country the rapid development of industrial production, rapidly improve degree of automation, implementation artifacts of handling, steering, transmission or toil for welding gun, spray gun, spanner and other tools for processing, assembly operations such as automation, should cause the attention of people more and more. Manipulator is to imitate the people part of the action, according to a given program, track and demanding acquirement, handling or operation of the automatic device. Applied in the industrial production of the manipulator is referred to as "industrial manipulator". Application manipulator can improve the automation of production water in production and labor productivity; Can reduce labor fatigue strength, to ensure product quality, implement safety production; Especially in high temperature and high pressure, low temperature, low pressure, dust, explosive, toxic and radioactive gases such as harsh environment, it instead of people normal work, the more significant. Therefore, in the machining, casting, welding, heat treatment, electroplating, spray painting, assembly, and light industry, transportation industry get more and more extensive application, etc. Manipulator institutional form is simple, strong professionalism, only as a loading device for a machine tools, special-purpose manipulator is attached to this machine. Along with the development of industrial technology, produced independently according to the process control to achieve repetitive operation, using range is wide "program control general manipulator", hereinafter referred to as general manipulator. General manipulator used to quickly change the working procedure, adaptability is stronger, so he is in constant tran...
