Description

Technical Field

[0001] The present invention relates to the technical field of welding tooling, and specifically to a friction stir welding tooling. Background Art

[0002] Friction stir welding uses frictional heat and plastic deformation heat as the welding heat source. A columnar or other shaped stirring pin with threads, etc. extends into the part to be welded of the workpiece. Through the high-speed rotation of the stirring pin, it generates heat by friction with the welding workpiece material, and then the material at the connection part is heated to reach a high-temperature plastic state. During the welding process, the rotating stirring head (mainly the shoulder) generates heat by friction with the workpiece surface, causing strong plastic deformation of the material on the advancing side of the stirring head. As the stirring head moves, the high-temperature plastically deformed material undergoes plastic flow and flows into the cavity behind the stirring head, forming a complete weld under the axial pressure.

[0003] In the prior art, most of the fixed positions of the friction stir welding tooling adopt a fixed type, which is not convenient to change, resulting in difficulty in welding at the fixed position of the product. It is necessary to replace the tooling multiple times. During welding, it is not very convenient to weld the product, affecting the welding efficiency of the product. At the same time, the tooling needs to be leveled before welding. When leveling the traditional tooling, workers need to insert pieces of paper at the four corners of the device for adjustment, resulting in more trouble during the adjustment of the device.
