Description

Technical Field

[0001] The utility model belongs to the technical field of robots, in particular to a displacement regulating mechanism for robot welding. Background Art

[0002] Robotic welding is a modern welding process that uses an automated robotic system to perform welding operations. In robotic welding, welding tasks are performed by specially designed welding robots. These robots are usually equipped with welding tools (such as welding guns or wire nozzles) and perform welding tasks through pre-programmed paths and parameters. Robotic welding usually covers various welding processes, including gas shielded welding (such as MIG / MAG welding), arc welding (such as TIG welding and arc welding), laser welding, etc.

[0003] The robot welding in the prior art cannot adjust the angle of the workpiece during welding, resulting in the inability to adapt to the shapes and sizes of different workpieces during welding, making it difficult to accurately align complex welding joints, affecting the welding quality and efficiency. At the same time, electromagnetic interference will be generated during the welding process, which will affect the positioning sensor, resulting in data errors or system failures. For this reason, we provide a displacement adjustment mechanism for robot welding to solve the above problems. Utility Model Content
