AI Technical Summary

⚠Technical Problem

The existing backfill-type friction stir spot welding spindle welding tool becomes stuck together after the aluminum material of the stirring pin and stirring sleeve cools and solidifies after the machine stops working. This makes it difficult to disassemble, affects production efficiency, and increases costs.

⚗Method used

By setting disassembly and assembly holes and set screw holes on the stirring sleeve and stirring pin, and realizing separate disassembly paths for the stirring pin and stirring sleeve through the tensioning component, and combining positioning parts and anti-rotation surfaces to ensure coaxiality, the traditional disassembly sequence is avoided and the processing cost is reduced.

🎯Benefits of technology

It enables the separate disassembly of the stirring needle and the stirring sleeve, ensuring the efficient operation of the welding production line, reducing disassembly costs, and improving coaxiality accuracy.

Abstract

The utility model belongs to the technical field of friction stir spot welding, especially a backfill type friction stir spot welding spindle welding tool mounting and dismounting structure. The utility model discloses a stirring needle welding tool and the stirring sleeve welding tool of setting outside stirring needle welding tool, and stirring sleeve welding tool is connected with stirring needle welding tool through the tensioning assembly of providing axial tensioning force. The stirring needle welding tool includes a stirring needle and a stirring needle rotating shaft. A jackscrew hole connected with a jackscrew is formed on the side wall of the stirring needle rotating shaft. A force applying groove matched with the jackscrew is formed on the outer wall of the stirring needle. When the jackscrew is locked, the stirring needle and the stirring needle rotating shaft are fixedly attached. The spot welding spindle welding tool mounting and dismounting structure can realize "separate dismounting and integrated removal", reduce the processing cost, and ensure the efficiency of the welding production line operation.
