Problems solved by technology
Thousands of tightening fatigue tests are required for each batch of product sampling, and parameters such as torque value and wrench temperature are recorded. In the traditional technology, this work is performed manually, and the workload is large, and the calibration and aging of each wrench are very difficult. To use many high-strength bolts, the cost is high

Embodiment Construction
[0009] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. The invention discloses an intelligent dynamic torque tester, which can realize closed-loop control and includes a mechanical part and a control part. The mechanical part includes the force application transmission system and the damping loading system. The force transmitted from the device under test is applied to the brake disc 1 through the dynamic torque sensor, and the reaction force transmitted from the damping loading system is also applied through the brake cylinder 9. on brake disc 1.
[0010] In this embodiment, the force application transmission system includes: a spline shaft II15 connected to the device under test and driven by the device under test; a dynamic torque sensor 3 connected to the spline sleeve 5 of the spline shaft II15; The dynamic torque sensor 3 drives the rotating brake disc 1 . The damping loading system inc...

The invention discloses an intelligent dynamic torque tester, which includes a mechanical part and a control part. The mechanical part includes a force application transmission system and a damping loading system. The force transmitted from the tested device is applied to the brake disc through a dynamic torque sensor. , the reaction force transmitted by the damping loading system is also applied to the brake disc through the brake cylinder. The beneficial effect of the present invention is that: the present invention can carry out torque calibration, aging and sampling tests on the measured devices such as constant torque wrench, the measured device is connected to the brake disc through the dynamic torque sensor, and the damping loading system transfers the reaction force through the brake cylinder Applied on the brake disc, and then through the control system, the test data is automatically transmitted to the computer for analysis and storage. The damping loading speed is adjustable, the loading is stable, and there is no noise. The invention has the advantages of simple structure, low cost, high degree of test automation and high reliability of test results.
Description
technical field [0001] The invention relates to the technical field of tool testing, in particular to an intelligent dynamic torque tester. Background technique [0002] In domestic bridges, wind power generation and power plants and other buildings, steel structure high-strength bolts are mostly used to complete the connection, and a constant torque electric wrench is used for tightening the high-strength bolts. Fixed torque electric wrench is also called torque adjustable electric wrench, which is a kind of electric wrench. Before the fixed torque electric wrench leaves the factory, the dynamic torque calibration of high-strength bolts must be carried out on the torque coefficient tester, and the dynamic aging of the product must be performed after the calibration is completed. Thousands of tightening fatigue tests are required for each batch of product sampling, and parameters such as torque value and wrench temperature are recorded. In the traditional technology, this w...
