Abstract
The utility model relates to the technical field of friction stir welding, in particular to a welding tool for assisting in assembling special-shaped workpieces, which comprises an assembling bottom plate, a supporting column and a clamping device, the supporting column and the clamping device are mounted on the assembling bottom plate, the assembling bottom plate is mounted on a working platform of friction stir welding equipment, an auxiliary table is arranged at the top of the supporting column, and the clamping device is mounted on the supporting column. An assembling platform is formed and is used for assisting in supporting and fixing the special-shaped workpiece; the multiple clamping devices are installed on the assembling bottom plate on the periphery of the auxiliary table, so that the baffle assemblies installed at the driving ends of the clamping devices can conduct releasable clamping operation on the side wall of the special-shaped workpiece fixed to the auxiliary table. In conclusion, by means of the collaborative design of the supporting protruding column, the multi-direction baffle and the inclined wedge clamping, the fixing problem of the special-shaped workpiece in the friction stir welding process is solved, high stability, operation convenience and process adaptability are achieved, and the production efficiency and the yield can be improved.
