High-stability steel door leaf welding platform

The utility model discloses a high-stability steel door leaf welding platform which comprises a supporting plate, pressing frames, a power mechanism and a reset structure, the pressing frames are installed on the two sides of the supporting plate in a rotating mode, and pressing pipes used for fixing a door leaf to be machined to the surface of the supporting plate are installed at the top ends of the pressing frames. A rope used for driving the pressing frame to rotate downwards is connected between the power mechanism and the pressing frame; a reset structure for providing power for upward movement of the pressing frame is arranged on the side face of the supporting plate, the rope is driven by the power structure to move downwards, and therefore the pressing frame is driven to move downwards, and a steel plate to be machined can be fixed through the pressing pipe; therefore, the rope cannot generate downward pulling force on the pressing pipe, then under the operation of the reset structure, the pressing f
