Rapid clamping device for gearbox body machining

The utility model relates to the technical field of clamping devices, and discloses a gearbox body machining rapid clamping device which comprises a bottom plate, a vertical plate is fixed to the top of the bottom plate, a mounting plate is fixed to the front face of the vertical plate, and a rotating seat is rotationally connected to the front face of the mounting plate. A first transverse plate and a second transverse plate are fixed to the two sides of the front face of the rotating base correspondingly. When a gearbox body is clamped, the gearbox body can be fully clamped through the threaded pins, the independent threaded pins can be better attached to grooves and protrusions on the surface of the gearbox body, the clamping stability is improved, the electric telescopic rod can be matched with the limiting hole to limit the rotating base, and the rotating base is not prone to falling off. According to the gearbox body clamping device, the gearbox body can be conveniently rotated for machining, and the pr
