Description

Technical Field

[0001] The utility model relates to the technical field of welding positioning, in particular to a high-precision welding positioning device. Background Art

[0002] Welding is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Some welding operations are performed by manually fixing the workpiece. Due to the accumulation of work fatigue as the working time, the workers cannot stay focused for a long time. There is a problem that the workpiece shakes during the welding process, affecting the welding effect and causing subsequent assembly difficulties. The use of a positioning device to fix the workpiece can overcome the problem of manual instability, but the structure of the general positioning device is fixed, and the direction of the workpiece cannot be adjusted after the workpiece is fixed. When there are multiple welding positions at different angles on the workpiece, the worker needs to repeatedly install and remove the workpiece from the positioning device, which is cumbersome to operate and reduces welding efficiency. In addition, a large amount of flying sparks will be generated during welding, which poses a safety risk of burning nearby workers, and corresponding protective structures need to be set up.
