机械手 Manipulator Can imitate the arms of the manpower and some action function, according to fixed program to grab, transporting or operating tool for automatic operation of the device. It can replace the hard labor in order to realize people the mechanization of manufacturing and automation, can in harmful environment operation to protect personal safety, and is widely used in mechanical manufacturing, metallurgy, electronics, light industry and atomic energy and other departments. Manipulator by hand and sports organizations main component. The hand is used to catch the workpiece (or tools) components, according to be grasped by the objects shape, size, weight, materials and operational requirements and have a variety of structure forms, such as the gripping type, the type and adsorption type , etc. Movement mechanism, make hand finish all kinds of rotation (swing), mobile or complex movement to achieve the specified action, change the position of the object were caught and position. The rise and fall of sports organizations, adjustable, and rotated independence movement way, called manipulator of freedom. In order to grab any space position and orientation of the object, need to have six degrees of freedom. Freedom is a machine designed off hand gave the key parameters. The more free degrees, the greater the flexibility of the manipulator, the more general broad, its structure is also more complicated. General robots for 2-3 degrees of freedom. The type of manipulator, according to drive mode can be divided into hydraulic, pneumatic, electric and mechanical manipulator; According to applicable range can be divided into robots for and general manipulator two; According to the trajectory control mode can be divided into position control and continuous track control robots. Robots are used for machine tools or other machines additional device, such as in the automatic machine or automatic production line loading and unloading and transfer on the processing
