High-precision torque detection device

Abstract

The invention relates to a high-precision torque detection device which comprises a working table, a guide rail base, a weight fixing mechanism and a torque output mechanism. The guide rail base is fixedly arranged on the working table. The weight fixing mechanism comprises a first fixing unit and a second fixing unit, the first fixing unit and the second fixing unit are used for fixing two end faces of a detected product, the first fixing unit is fixedly arranged on the working table and located on any side of the length direction of the guide rail base, a gap is formed between the first fixing unit and the guide rail base, the second fixing unit is arranged on the guide rail base in a sliding mode and slides back and forth in the length direction of the guide rail base, and the torque output mechanism is arranged below the first fixing unit. The first fixing unit and the second fixing unit of the high-precision torque detection device are used for fixing the two end faces of the detected product, so that fixation stability and measurement accuracy are guaranteed; the distance between the second fixing unit and the first fixing unit can be adjusted according to the length dimension of the detected product, and the high-precision torque detection device is applied to measuring products of different dimensions; the torque output mechanism is used for providing torque for the detected product, so that the torque is detected.

Description

technical field [0001] The invention belongs to the technical field of torque detection machinery, and in particular relates to a high-precision torque detection device. Background technique [0002] With the progress of society and the development of science and technology, people have higher and higher requirements for the safety performance of the items used in life. In order to ensure the safety of equipment operators, various industries have produced a variety of devices to test the safety of products. [0003] In today's industrial equipment, many equipment products, especially large-scale equipment and key parts of equipment, are connected by bolts and nuts for future repair and maintenance. For example: thermal power equipment, hydropower equipment, nuclear power equipment, wind turbine equipment, metallurgical equipment, mining equipment, shipbuilding equipment, petroleum and petrochemical equipment, etc. have tens of thousands of large bolts for the connection of t...

AI Technical Summary

Problems solved by technology

However, the torque setting of these torque tools or equipment is calculated theoretically by the manufacturer or calibrated by a foreign torque sensor. After being used in China for a period of time, it cannot be re-calibrated in China, resulting in failure of many key equipment in China. Torque connection failure of component bolted connections

In severe cases, it will cause leakage and explosion of chemical plants, leakage and pollution of oil depots, collapse of wind turbines, etc.

The calibration and detection of the real torque of its torque tools or equipment has not been a stable and reliable torque detection device in China.
