Movable wrench double-face polishing clamp

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of hardware tool processing, in particular to a double-surface polishing jig for an adjustable wrench. Background technique [0002] A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is usually formed with a clamping handle at one or both ends of the handle to apply an external force to the handle to twist the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank in the direction of thread rotation, so that the bolt or nut can be twisted. [0003] The existing wrenches are divided into two types: fixed type and movable type. The movable type wrench is divided into two types: one is adjustable wrench teeth, which can adapt to different types of fasteners within a certain range...

Problems solved by technology

[0003] The existing wrenches are divided into two types: fixed type and movable type. The movable type wrench is divided into two types: one is adjustable wrench teeth, which can adapt to different types of fasteners within a certain range; however, this kind of movable type When the surface of the wrench is polished, the existing technology can only manually place the fixtures one by one for processing, and the positioning is inaccurate, resulting in a waste of a lot of manpower during the polishing process, low production efficiency, and due to inaccurate positioning, it is often easy to cause some movable wrenches to appear. Over-processing, but some wrenches are not processed in place
