Design Of Welding Robot Workstation Of Heavy Truck Cab

This paper based on the project "Jiang Huai Heavy Truck Cab Robot Welding Line" which design by School of Mechanical and Automobile Engineering,HeFei University of Technology.The project would develop a robot welding workstation based on the technological process of heavy truck cab welding line,included the structure design and control system design to realize the autowelding of heavy truck cab,improve the work efficiency of heavy truck cab welding line and product quality,reduce manufacture cost, increase sales volumn in the market competition.This paper presented the design method of the robot welding work station according to the overall arrangement of JiangHuai Gallop truck cab welding line, established the kinematics model of HX165 industry robot which applied in the project,analysed the kinematics equation of HX165 industry robot,listed each transformation matrixs between connecting rods,solved the forward kinematics and the inverse kinematics of HX165 industry robotprovided basis of effective control to welding robot.In the workstation control system based on site concentration line technique,studied and possessed the influence of main welding technological parameters to welding quality,set them in logical value considered with the result of site experiment.it also detailed explained the workstation control method and some key question.it can be referenced by others when they design the similar welding workstation.
