This utility model belongs to the field of steel structure production equipment, and particularly relates to a fixed transmission device for spot welding H-beams. It includes a roller conveyor frame for conveying H-beams, and a spot welding fixing mechanism is also provided on the roller conveyor frame. The spot welding fixing mechanism includes a portal frame covering the roller conveyor frame and a top plate cylinder disposed on the top of the portal frame. The power end of the top plate cylinder extends through the top of the portal frame and is connected to a lower pressure wheel assembly. A web plate cylinder is also provided on the portal frame, symmetrically arranged on both sides above the roller conveyor frame. The power end of the web plate cylinder is connected to a web plate wheel assembly for clamping the web. This utility model utilizes the roller conveyor frame to convey the H-beams and the spot welding fixing mechanism to achieve sliding fixing of the flanges and web of the H-beams, thereby facilitating the maintenance of the H-beam's shape during sliding and thus facilitating spot welding.
