Abstract: Robot welding pliers are an important equipment for automated cab welding lines, mainly composed of welding transformers, clamp arms, cylinders, grip rods, electrodes, etc. The structure of the welding pliers is usually designed based on the numerical simulation of the driver's cab body and the welding fixture of the body welding line. In this article, the robot welding pliers encountered special structures in the cab body according to product development requirements. Although the designed robot welding pliers can complete the established welding work, there may be situations where the quality of the welding points does not meet the welding quality standards during operation. Based on this issue, the article analyzes the structural characteristics of robot welding pliers and designs a welding tongs structure that can combine linear guide sliders with welding pliers to enhance the stability of welding pliers, improve the appearance quality and welding strength of welding joints in the cab, and provide necessary guarantees for enterprise product quality control.
