In order to solve the problem that the current docking mechanism of the docking lock differential combination test cannot be met, an in-situ calibrated docking lock differential combination torque measurement device is designed. The calibration device uses the torque transmission shaft to differentially lock the docking lock in high and low temperature environments. The combined torque value is transmitted to the normal temperature environment for measurement, and the in-situ calibration of the measured torque sensor is achieved through a clever design. Analyze the error sources of the device, and distribute the errors according to the device technical indicators. The calculation results show that the designed in-situ calibrated butt lock differential combination torque measuring device has a measuring system of 2.25%, and the maximum allowable error of the calibration system is 0.62%, which meets the technical specifications of the device.
