Self-adaptive boring spot welding device

The invention discloses a self-adaptive boring spot welding device, belongs to the technical field of boring spot welding, and aims to solve the problems that the variety of required pipes is more, process equipment is complicated, the production cycle is continuously prolonged, the positioning effect of a tool is continuously weakened, the machining quality of parts is difficult to guarantee, and the production efficiency is reduced. The material conveying machine position can move left and right relative to the upper surface of the auxiliary base, one set of assembling spot welding machine position and boring machine position can be close to or away from the other set of assembling spot welding machine position and boring machine position, position control of pipes is facilitated, the device can be suitable for the pipes of different sizes, and the device is wide in application range; the conical head conveying rail table is arranged on one side of an assembly spot welding machine position so that conical h
