Multi-degree-of-freedom turnover device for reversing of stir-friction spot welding machine

The utility model provides a multi-degree-of-freedom turnover device for reversing of a stir-friction spot welding machine. The multi-degree-of-freedom turnover device for reversing of the stir-friction spot welding machine comprises lifting lug assemblies, a lifting beam, a lifting beam dismantling buckle, transition fulcrums, purpose-made lifting points, a steel wire rope, a lifting point dismantling buckles and pulleys, wherein the lifting beam dismantling buckle is located above the lifting beam, the upper ends of the lifting lug assemblies are installed at the two ends of the lifting beam, two rolling bearings which are connected in parallel are installed at the lower ends of the lifting lug assemblies, the pulleys are in close fit with the outer circles of the rolling bearings, the steel wire rope is installed in grooves of the pulleys, the lifting point dismantling buckles are installed on the two sides of the steel wire rope, and the purpose-made lifting points are installed on the lifting point dismantling buckles, and the transition fulcrums are installed on the purpose-made lifting points and are connected with a machine head of the stir-friction spot welding machine. The multi-degree-of-freedom turnover device for reversing of the stir-friction spot welding machine solves the problem that an existing stir-friction spot welding machine does not have the multi-degree-of-freedom turning function, and spot welding at different spatial positions is achieved.
