Problems solved by technology

The tire bolt tightening machine is generally a five-axis tightening machine, each axis is evenly distributed in a ring, and the tire bolt tightening machine has a certain rotation angle to facilitate the alignment with the hub bolts, so in the daily calibration process (usually single-axis calibration one by one) , usually choose the dynamic calibration mode, due to the large fluctuation of the tightening shaft swing, the strain current of the torque sensor will fluctuate, resulting in unstable calibration results and unreal torque, and because of the large swing range, there are certain risks to the safety of the calibration personnel risk
In order to eliminate the quality risk caused by inaccurate calibration torque, a static calibration method must be adopted, so it is imperative to invent a calibration auxiliary device
