Static Simulation and Structure Optimization of Key Parts of Joint Welding Robots

Welding robot has a high degree of intelligence, automation and other characteristics in the field of welding, but the serial structure of the robot makes it lack of overall rigidity, which seriously affects the positioning accuracy of the robot and greatly reduces the quality of welding. In order to solve these problems, we use the six-degree-of-freedom joint robot as the research object, and carry out the static simulation of its fundamental components. Firstly, the overall structure of the welding robot is introduced. Then, according to the structural performance and working requirements of the robot, we solved the load of the key components of the robot under the extreme conditions. We used the finite element software ANSYS Workbench to perform finite element static analysis and verified the reliability and rationality of the designed welding robot joints. And the structure of the welding robot's arm is optimized, which serves as a theoretical basis for the actual processing of the welding robot.
