Take the following diagram as an example, the tightening torque meets the requirements, but because the tightening process cannot meet the requirements (the torque can be achieved by turning 200°, but this point needs to rotate more angles to achieve the torque), it is judged as unqualified, and it is possible Causes subsequent false torque problems, and the connection fails.

Intelligent recognition of the tightening process
 
   Through the soul of stepping on the wrench, let us know how to tighten the bolts and nuts of the car factory.
