Abstract
Industrial manipulator is a kind of automatic devices, which substitutes people to carry out dangerous or duplicate work. It complies crawler tracks、handling work or manage or operate a tool according to set procedures and requirements. It is constituted with executive body、drive system and control system. In this paper, it has shortly introduced the position connection and work process between manipulator and other equipments. It has also given a relatively minute discussion of the manipulator overall plan, especially have compared the different projects to realize the require action and then given out the final scheme. According to the motion requirements of the manipulator’s arm, it has adopted cylindrical coordinate manipulator. The number of the manipulator’s freedom is four: up-down and rotating of the big arm, the straight reciprocating motion of the small arm, revolving movement of the wrist. The fingers of the manipulator have adopted the two-points sustain round structure. The power drive of manipulator is to be used is hydraulic system and control program for points for control type. This design is mainly consist of the design of large arm take-off and landing and rotating, the structural design of arm and telescopic arm, structural design of hand. What I mainly design is the structural design of large arm take-off and landing and rotation, and I carry out the theoretical analysis and comparison of hydraulic system.
