Automatic cantilever welding equipment

The invention relates to the field of welding positioning, in particular to automatic cantilever welding equipment. The technical problems that in the prior art, the efficiency of aligning small round pipes to round holes is low, alignment is not accurate enough, and in the welding process, two round pipes are prone to loosening during welding, so that the welding quality is poor are solved. Automatic cantilever welding equipment comprises a base, side plates, a welding cantilever, a frame body and the like. A side plate is installed on one side of the upper portion of the base, a welding cantilever is installed on the side face of the side plate, and a frame is installed on the base. Two pressing racks are separated from two pressing gears, under the action of a torsion spring, a pressing frame and a pressing ball can make contact with one side of a circular pipe, the pressing frame and the pressing ball can drive the circular pipe to move in the direction close to a baffle, and therefore the transverse dire
