Filter installation support shape correction positioning spot welding tool and method

The invention discloses a shape-righting, positioning and spot-welding tool for a filter mounting bracket, belongs to the technical field of filter mounting bracket processing, and solves the problems of low efficiency and low welding precision caused by traditional manual splicing and spot welding of the filter mounting bracket. The clamp comprises a workbench, a positioning ring used for positioning a hoop is arranged on the workbench, a clamping mechanism used for clamping a connecting lug is arranged on the workbench on one side of the positioning ring, and a positioning assembly used for positioning the position of a bracket is arranged on the workbench on the other side of the positioning ring. A pushing mechanism capable of pushing the bracket to be close to the positioning ring is arranged on the workbench on the side, away from the positioning ring, of the positioning assembly, and the output end of the pushing mechanism is connected with an extrusion die used for installing the bracket.
