Reversible deformation jig frame with adjusting function for steel box girder production

The invention relates to the technical field of welding, in particular to an anti-deformation jig frame with an adjusting function for steel box girder production. Comprising a base, the base is slidably connected with first electric sliding blocks distributed in a rectangular array mode, the first electric sliding blocks are fixedly connected with first elastic telescopic rods, the telescopic ends of the first elastic telescopic rods are rotatably connected with a connecting frame, the connecting frame is fixedly connected with a lower clamping block, and the connecting frame is fixedly connected with first hydraulic telescopic rods; a connecting frame is arranged on the base, an upper clamping rod is slidably connected to the connecting frame, a second hydraulic telescopic rod is fixedly connected to the base, a third hydraulic telescopic rod is fixedly connected to the base, and a supporting roller is arranged on the base. The thickness of the steel box girders is detected through the upper clamping rods a
