Self-adaptive pressing welding tool

The utility model provides a self-adaptive pressing welding tool. The self-adaptive pressing welding tool comprises a machine base, a welding platform connected with the machine base, at least two reference mechanisms and at least two jacking mechanisms. A plurality of first supporting pieces are symmetrically arranged on the front face of the welding platform in the first direction. The reference mechanism is arranged on the welding platform in the first direction, and the reference mechanism can move in the first direction to provide a placement reference for a to-be-welded part; the jacking mechanisms are symmetrically arranged on the front face of the welding platform in the first direction, and the jacking mechanisms can be driven by the jacking mechanisms to move in the second direction perpendicular to the first direction. After the to-be-welded parts are positioned and placed on the supporting part, the two to-be-welded parts are tightly jacked through respective driving of the jacking mechanisms, and
