螺塞密封垫错漏装的自动识别

Automatic Identification of Plug Screw Gasket Wrong or Miss Assembled

针对由于发动机螺塞安装不到位产生扭矩虚假或密封垫错漏装等问题,提出通过监控螺塞拧紧过程中的旋转角度,间接控制拧紧过程的方法;并通过数据统计方法制定出合理的角度监控区间。实际应用表明:该方法可自动识别密封垫的错漏装,并可判断过程一致性;有效降低了管理成本和质量风险。

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.
