How to use an auxiliary device for calibrating dynamic torque assembly tools

Abstract

Auxiliary device for calibrating dynamic torque assembly tools and its use method, including: guide frame, standard dynamic torque sensor, test nut, base, secondary adapter connector, main support frame, main adapter connector, radial thrust bearing; The guide frame, the main support frame and the base are connected from top to bottom, the radial thrust bearing is installed on the guide frame, the test nut is installed on the bottom of the main support frame, and the main adapter connector assembles the standard dynamic torque sensor and the calibrated dynamic torque The tool is connected, and the secondary adapter connects the standard dynamic torque transducer and the test nut. Ensure the parallelism between the upper and lower end surfaces of the guide frame, the upper and lower end surfaces of the main support frame, and the upper surface of the base, and ensure the coaxiality between the radial thrust bearing and the test nut. The method provided by the invention simulates the actual working state, makes the calibration condition of the dynamic torque assembly tool consistent with the use condition, can well reproduce the calibration value, and achieves the purpose of accurate value transmission.

Description

technical field [0001] The invention belongs to the field of metrology, and relates to a method for using an auxiliary device for calibrating dynamic torque assembly tools. 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. Therefore, the calibr...
