Description

Technical Field

[0001] The present disclosure relates to the field of sensor technology, and in particular to a clamping force coefficient measurement system and a composite tension and pressure sensor device. Background Art

[0002] In the current industrial manufacturing and machinery maintenance fields, the widespread use of torque wrenches reflects the high attention paid to the tightness and stability of bolt connections. However, traditional torque wrench detection tools generally have problems such as complex structure, single function, and low efficiency. These limitations seriously restrict the improvement of work efficiency and the guarantee of measurement accuracy. With the growing market demand for efficient and accurate detection tools, traditional detection tools can no longer meet the urgent needs of industry development.

[0003] Traditional testing tools are often complicated, which not only increases the manufacturing cost, but also increases the difficulty of operation, which is not conducive to fast and accurate measurement; most testing tools only have a single measurement function, such as only being used to measure torque or tension, and cannot meet multiple measurement needs at the same time, reducing work efficiency; due to their complex structure and relatively single function, traditional testing tools often need to be replaced or adjusted multiple times during the measurement process, resulting in low measurement efficiency; the bolt clamping force coefficient is a key parameter of bolt connection performance, and its measurement is difficult, and traditional testing tools often find it difficult to provide accurate and reliable measurement results.

[0004] Among them, the bolt clamping force coefficient is an important indicator to measure the performance of bolted connections, and is closely related to factors such as bolt preload and material properties. Selecting an appropriate clamping force coefficient is crucial to improving the stability and reliability of bolted connections. However, direct measurement of the bolt clamping force coefficient is difficult and usually requires the use of complex experimental equipment and professional operating skills. In contrast, the generation and measurement of torque is relatively simple, so indirectly calculating the clamping force coefficient through torque has become an important method.
