it. Production of mechanical hand can increase the automation level of production and labor productivity。 can reduce labor intensity, ensuring product quality, to achieve safe production。 particularly in the hightemperature, high pressure, low temperature, low pressure, dust, explosive, toxic and radioactive gases such as poor environment can replace the normal working people. Here I would like to think of designing a robot 设计巴巴工作室 to be used in actual production. Why would a robot designed to provide a pneumatic power: pneumatic robot refers to the pressed air as power sourcedriven robot. With pressuredriven and other energydriven parison have the following advantages: 1. Air inexhaustible, used later discharged into the atmosphere, does not require recycling and disposal, do not pollute the environment. (Concept of environmental protection) 2. Air stick is small, the pipeline pressure loss is small (typically less than asphalt gas path pressure drop of onethousandth), to facilitate longdistance transport. 3. Compressed air of the working pressure is low (usually 4 to 8 kg / per square centimeter), and therefore moving the material ponents and manufacturing accuracy requirements can be lowered. 4. With the hydraulic transmission, pared to its faster action and reaction, which is one of the advantages pneumatic outstanding. 5. The air cleaner media, it will not degenerate, not easy to plug the pipeline. But there are also places where it fly in the ointment: 1. As the pressibility of air, resulting in poor aerodynamic stability of the work, resulting in the implementing agencies as the precision of the velocity and not easily controlled. 2. As the use of low atmospheric pressure, the output power can not be too large。 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 设计巴巴工作室 is better. Compared with the hydraulic transmission, and its faster action and reaction, which is one of the outstanding merits of pneumatic. Clean air medium, it will not degenerate, not easy to plug the pipeline. It can be safely used in flammable, explosive and the dust big occasions. Also easy to realize automatic overload protection. Second, the position, mechanical hand Robot in the form of a variety of forms, some relatively simple, some more plicated, but the basic form is the same as the position of the , Usually by the implementing agencies, transmission systems, control systems and auxiliary devices posed. 1. Implementing agencies Manipulator executing agency by the hands, wrists, arms, pillars. Hands are crawling institutions, is used to clamp and release the workpiece, and similar to human fingers, to plete the staffing of similar actions. Wrist and fingers and the arm connecting the ponents can be up and down, left, and rotary movement. A simple mechanical hand can not wrist. Pillars used to support the arm can also be made mobile as needed. 2. Transmission The actuator to be achieved by the transmission system. Subtransmission system monly used manipulator mechanical transmission, hydraulic transmission, pneumatic and electric power transmission and other drive several forms. 3. Control System Manipulator control system39。 s main role is to control the robot according to certain procedures, direction, position, speed of action, a simple mechanical hand is generally not set up a dedicated control system, using only trip switches, relays, control valves and circuits can be achieved dynamic drive system control, so that implementing agencies according to the requirements of action. Action will have to use plex programmable 设计巴巴工作室 robot controller, the microputer control.。
