摘要
发动机装配过程的螺栓拧紧受拧紧设备、零件本身材质、质量、表面等各项因素影响,零部件扭矩最终考核的是夹紧力是否符合要求,因此,装配过程的扭矩监控是一项重要又复杂的工作。运用SPC工具,对拧紧过程进行监控,查找变异点,分析原因制定对策,使得过程能力符合要求。
Bolt torque affected by screw equipment,parts texture,parts quality and parts surface in engine assembly process. If the clamp force meets the requirement or not was final check of torque,so torque control is a importance and complex work in engine assembly process. Use the SPC,find the change point,analyze the root cause and action to make process capability meets the requirement.
