Movable wrench double-face polishing clamp

The invention discloses a movable wrench double-face polishing clamp. The movable wrench double-face polishing clamp comprises a bottom plate and an overturning device arranged in the middle of the bottom plate, and the overturning device is provided with an overturning through hole. The movable wrench double-face polishing clamp further comprises a rotation rod, limiting steel plates and positioning devices, wherein the rotation rod penetrates the overturning through hole and through holes in the tail ends of handles of movable wrenches in an inserted manner, the limiting steel plates are symmetrically arranged at the inner end of the upper surface of the bottom plate with the overturning device as the center, and the positioning devices are arranged at the outer end of the upper surfaceof the bottom plate. The bottom plate is provided with two grooves for limiting the straight line where the movable wrenches are placed, a calibration rod penetrates through holes of the movable wrenches, all the movable wrenches are fixed to a clamp through the three-point positioning principle, simultaneous batched and accurate movable wrench polishing can be finished, the overturning device serves as the center for symmetric arrangement, the other surface can be machined after overturning, two faces can be machined through one-time feeding, manpower is further saved, and the work efficiencyis improved.
