摘　　要：目前航空发动机总装检验过程中存在诸多痛点,线性的装配检验方式灵活性低、适应性较差,同时对人的需求极高,极易产生错检、漏检,对装配节拍以及周期有极大的影响。本文设计了一种基于分类抽样的发动机总装检验方案,通过对检验对象的分类,针对不同对象设计检验方案,以此为基础规划了基于分区的检验路径,通过对方案的分析及验证,证明了抽样检验方案的合理性,提升了总装检验的精确性和可靠性。There are many pain points in the current aviation engine final assembly inspection process.The linear assembly inspection method has low flexibility,poor adaptability,and extremely high human demand,which is prone to errors and omissions,and has a great impact on the assembly rhythm and cycle.This article proposes a classification sampling based engine final assembly inspection plan.By classifying the inspection objects and designing inspection plans for different objects,a partition based inspection path is planned based on this.Through analysis and verification of the plan,the rationality of the sampling inspection plan is proved,and the accuracy and reliability of the final assembly inspection are improved.
