Electronic torque wrench

Abstract

The invention relates to the field of special tools, in particular to an electronic torque wrench. The electronic torque wrench comprises a wrench body and a control system. The wrench body comprisesa handle and a bayonet. The bayonet is connected to one end of the handle, and an included angle between the bayonet and the handle can be adjusted. The control system comprises a torque sensor, a control unit, an instruction input unit, an alarm unit and a storage unit for storing data. The torque sensor is arranged on the bayonet and is used for measuring torque size output by the bayonet. The control unit is used for receiving an instruction input by the instruction unit and control the alarm unit to issue an alarm according to the data of the torque sensor. The torque sensor monitors the torque size applied by the bayonet to a screwed joint. If torque applied by the bayonet to the screwed joint is too large, the control unit controls the alarm unit to issue the alarm to avoid causing damage to the joint due to excessive force. At the same time, an angle between the bayonet and the handle of the torque wrench can be adjusted, so that the wrench can be applied to locations with limited space.

Description

technical field [0001] The invention relates to the field of special tools, in particular to an electronic torque wrench. Background technique [0002] Based on the power supply mechanism, most of the pipes in the auxiliary cooling system of the high-voltage converter are custom-made plastic pipes, and the joints are plastic processed parts. When twisting the joints, the torque required for each joint of the pipeline is different, so that the workers not only need to be familiar with and record the torque of each joint, which requires high requirements for the workers. [0003] Pipelines are laid in complex stations, and the operating range and space are often limited, and conventional torque wrenches cannot be operated well. In order to solve this technical problem, the prior art provides a bendable torque wrench. After the wrench is bent at different angles, when the same amount of force applied by the human body to the wrench is transmitted to the joint, the magnitude o...

AI Technical Summary

Problems solved by technology

After the wrench is bent at different angles, when the same amount of force applied by the human body to the wrench is transmitted to the joint, the magnitude of the moment is different, which leads to different forces on the joint

This also makes it difficult for workers to control the size of the applied force, and the construction efficiency is low.
