ABSTRACT

This topic mainly production spool and sleeve type parts automatic feeding mechanism design. The design is part of the manipulator, the production spool and sleeve type parts automatic feeding mechanism is the development of mechanization and automation of the production process of a new type of device to achieve the blank to grab, automatic positioning, clamping and workpiece playback. Mechanical hand can replace the human to complete the boring work, improve labor productivity, reduce labor intensity. The organization covers the position control technology, programmable control technology, detection technology, etc.. This topic design of the hydraulic manipulator can grasp the object in space, flexible and diverse movements. According to the change of workpiece and production technology requirements at any time to change the relevant parameters, can be used to replace manual work in the high temperature danger zone.

Key words：mechanical hand, automatic loading and unloading mechanism, lifting, rotation
