Design Of Mechanical And Electrical System Of Welding Robot Arms

In this context,industrial robots automation equipment as a means of relieving labor force and improving product quality and efficiency has become particularly important as a very important welding in automation equipment.In this context,automobile industry,automobile manufacturing,mechanical engineering,electronic power and other industries have developed rapidly.Robot arm technology has become an important part of the working conditions of welding workers can be effectively improved,productivity can be improved.Among them,six degrees of freedom welding robot arm because of its three-dimensional space movement of the high degree of flexibility and concern.Therefore,in this paper,six-degree-of-freedom welding robot arm as the research object,design its electromechanical system,the specific completion of the following:First,according to the welding process route and welding processing technology requirements,the design of the six-degree-of-freedom welding machine arm overall program.The three-dimensional model of the key components such as frame,fuselage and wrist was established.On this basis,the overall assembly diagram of the six-degree-of-freedom welding machine arm was completed.The end curve and velocity curve of the robot arm were obtained by MATLAB software and ADAMS software.The results of the joint simulation were analyzed.Second,the robot arm control system hardware design,including: industrial computer,motion controller,PLC,PMAC selection,motor and reducer calculation selection,electrical cabinet parameters to determine,and the connection between these hardware the way;The software of the robot arm control system is designed,which includes the design of the control software function ?structure analysis and teaching software system.Finally,the robot is debugged and run by the teaching system,and its manual and program automatic functions are tested.The results show that the design of the mechanical and electrical system of the robot arm is feasible and can work reliably and reliably.The experimental data provide the basis for further optimization of the follow-up system.
