[0002] Torque multipliers are widely used in the process of modern industrial production assembly and on-site installation. The accuracy of torque multipliers directly affects the quality of assembly and installation. Ensuring the accuracy of torque multipliers is crucial to controlling the assembly quality of high-strength bolts and preventing safety risks. Since the calibration of torque multipliers is affected by the input and output torque accuracy and radial offset load, the calibration of torque multipliers has always been a difficult point in the traceability of measurement values ​​in mechanical metrology.

[0003] At present, the torque multiplier needs to be calibrated during the mass production process. In the process of connecting the torque multiplier with the torque meter and the torque wrench, the torque wrench and the input port of the torque multiplier need to be manually connected.

When manually applying torque to the input end of the torque multiplier through the torque wrench, the force of manually pulling the torque wrench is not uniform, and it is inevitable that the torque wrench will be damaged by pulling the torque wrench too much. When manually applying torque to the input end of the torque multiplier through the torque wrench, the manually pushed torque wrench is very likely to slide and tilt, resulting in the inability to fully apply the torque to the input end of the torque multiplier, causing deviations in the test data, thereby affecting the accuracy of the calibration.
