Problems solved by technology
The inspection method in the prior art is to use a standard sample for calibration. This method is difficult to ensure that the state of the sample does not change for a long time, resulting in inaccurate calibration results.
Or use a torque wrench with a special joint or tooling to pull the torque sensor for calibration. This method is easily constrained by cost and space, and the calibration of the torque wrench itself is also a big difficulty

Description
technical field [0001] The invention belongs to the technical field of torque sensor detection, and more specifically relates to a torque sensor accuracy checking device. Background technique [0002] At present, various industrial parts have strict requirements on the assembly process of the torque sensor, and the requirements on the performance testing of the torque sensor after assembly are also very strict, and the accuracy of the torque sensor needs to be verified before the performance testing begins. The inspection method in the prior art is to use a standard sample for calibration. This method is difficult to ensure that the state of the sample does not change for a long time, resulting in inaccurate calibration results. Or use a torque wrench with a special joint or tooling to pull the torque sensor for calibration. This method is easily constrained by cost and space, and the calibration of the torque wrench itself is also a big difficulty. SUMMARY OF THE INVENTIO...
