[0002] Welding technology is a commonly used processing method in the existing mechanical processing field. When welding general parts, it is often necessary to change their position to facilitate welding. The position change of parts is usually achieved by manually flipping them. When the parts are flipped to the position where welding is required, they are positioned again for precise welding.

[0003] However, manually flipping the welded parts can easily increase the position error, thereby reducing the welding accuracy of the welded parts. At the same time, the operation process of manually flipping the welded parts is time-consuming and labor-intensive, which reduces the welding efficiency. In view of this, we propose a flipping and positioning device for welding. Utility Model Content
