Accurate positioning laser welding machine

The utility model relates to the technical field of laser welding machines, and discloses a precise positioning laser welding machine which comprises a placing plate, a base is fixedly assembled at the bottom of the placing plate, a positioning frame is fixedly assembled at the top of the placing plate, a welding machine head is fixedly assembled at the bottom of the positioning frame, a protective cover is fixedly assembled on the outer edge of the welding machine head, and the protective cover is fixedly assembled on the bottom of the placing plate. A laser transmitter is fixedly assembled at the bottom of the protective cover, and a square groove is formed in the top of the placing plate. The laser emitter emits a light source to project the light source to the surface of a clamped object, then the accuracy of a welding point position is guaranteed, the problem that the welding stability is seriously affected due to the fact that the welding point is prone to deviation during welding is solved, meanwhile,
