Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary equipment, in particular to a welding part anti-deviation positioning device. Background Art

[0002] The application range of welding technology is extremely wide, so the parts connected by welding process are also diverse. When welding parts, it is usually necessary to initially fix the parts so that the gap between the parts is in a stable state, so as to facilitate the welding device to locate the gap and weld.

[0003] When welding some larger plates, spot welding is usually required before full welding. Since the material strength around the weld decreases after welding, in order to ensure the flatness of the weld during full welding, the plate, especially the area near the weld, will be fixed. Due to the presence of a heat-affected zone during welding, the fixing device is usually a certain distance away from the weld. Some larger plates will have the connection of the parts slightly offset downward due to the influence of gravity, thus affecting the flatness after welding. Utility Model Content
