Description

An integrated wrench for hexagon socket bolts

technical field

The invention belongs to the technical field of mechanical manufacturing tools, and in particular relates to an integrated wrench for inner hexagon bolts.

Background technique

As the mechanical processing manufacturing industry tends to be more and more miniaturized and lightweight, people try to meet the miniaturization and lightweight design requirements for the manufacturing and processing of each component in the overall assembly. As far as ordinary connecting bolts are concerned, hexagonal socket bolts are widely used in mechanical manufacturing and assembly due to their small structural size and low consumables. However, because the hexagonal socket bolt has small structural size, various types, and different models, the wrench for tightening the hexagonal socket bolt has small structural size, various types, and inconvenience to carry, especially from clamping bolts to elastic bolts. . For the staff who disassemble and assemble parts, the work efficiency is low, and the wrenches are many and easy to lose. At the same time, the hexagonal socket bolts of different types need to be replaced frequently, which not only increases the workload of the staff, but also reduces the workload. Efficiency, so ordinary wrenches can no longer meet people's needs. Therefore a kind of simple, convenient, practical mechanical tool will be expected by people.

At present, the working process of the ordinary hexagonal socket wrench is as follows: first select the wrench that matches the elastic hexagonal socket bolt, then find the position where the mouth shape of the hexagonal socket bolt matches the mouth shape of the wrench, and finally apply a rotational torque to the wrench handle and repeat at the same time The above process is performed until the hexagon socket bolt is removed or tightened. However, for different types of hexagon socket bolts, it is necessary to replace different types of wrenches, and the above process needs to be repeated every time a different type of hexagon socket bolt is disassembled. If there are several types of bolts on a component, several types of wrenches must be carried. wrench. Due to the small size of the hexagonal socket wrench, it is difficult to apply a tightening moment to the wrench arm, which brings a lot of inconvenience to the disassembly or installation work. It is not only inconvenient to disassemble or install different types of hexagonal socket bolts with respect to the above-mentioned common wrench, but also the process is loaded down with trivial details, heavy workload, and also reduces work efficiency.
