| Abstract:Aiming at the false torque of engine's plug screw because of not-in-place installation, and wrong or missing assembly of plug screw gasket, the solutions were given by controlling the rotation angle of the plug screw during tightening, thus the process of tightening was controlled indirectly. And the effective angle monitoring interval was setting based on data statistics. Application results show that this method could identify wrong or missing assembly of gasket automatically, and could judge the process consistency, and ultimately reduce management cost and quality risks. |
