Auxiliary device for calibrating dynamic torque assembly tool and method of using same

Abstract

An auxiliary device for calibrating a dynamic torque assembly tool and a method of using same are disclosed. The auxiliary device comprises a guide frame, a standard dynamic torque sensor, a test nut, a base, a sub adapter connector, a main support frame, a main adapter connector and a radial thrust bearing, wherein the guide frame, the main support frame and the base are connected from the top to the bottom, the radial thrust bearing is mounted on the guide frame, the test nut is installed at the bottom of the main support frame, the main adapter connector connects the standard dynamic torque sensor with a dynamic torque assembly tool to be calibrated, and the sub adapter connector connects the standard dynamic torque sensor with the test nut. Parallelism among the upper and lower end faces of the guide frame, the upper and lower end faces of the main support frame and the upper surface of the base is ensured, and the coaxiality between the radial thrust bearing and the test nut is also ensured. According to the method provided by the invention, the actual working condition can be simulated, so that the calibration condition and the using condition of the dynamic torque assembly tool are consistent, and the calibrated value can be well reproduced to achieve the accurate transmission of the value.

Description

technical field [0001] The invention belongs to the field of metrology, and relates to an auxiliary device used for calibrating a dynamic torque assembly tool and a using method thereof. Background technique [0002] With the rapid improvement of the manufacturing level, the commonly used dynamic torque assembly tools, including tightening machines, pneumatic wrenches, and electric wrenches, are more and more used in During screw connection assembly. The assembly quality of dynamic torque assembly tools is not only related to product quality, but also closely related to safety. Therefore, measurement management and control should be carried out on dynamic torque assembly tools, and the accuracy and reliability of output torque values ​​can be ensured through calibration. [0003] However, since such tools add a dynamic torque sensor to the power system, the sensor continuously collects torque signals in real time during rotation to control the output torque value. Therefo...
