摘　　要：通过对机油泵衬套使用过程失效模式分析及基于过盈联接的压装过程分析,确定其装配过程关键质控点,接触应力p主要取决于过盈量δ和2个配合件的弹性模量,压装质量可以直接通过压装过程的压入力F和压入深度l进行评定。通过对机油泵衬套压装设备结构优化改进,增加压装力及位移监控,能够有效评定机油泵衬套压装质量并进行不断优化,避免售后质量事故的发生。This paper,by analyzing the failure mode of oil pump bushing during use and the press fitting process based on interference connection,determined the key quality control points of its assembly process,the contact stress p mainly depended on the interference amountδand the elastic modulus of the 2 mating parts,the press-fitting quality can be directly evaluated by the press-in force F and the press-in depth l during the press-fitting process.By optimizing and improving the structure of oil pump bushing press-fitting equipment,increasing the press-fitting force and displacement monitoring,the press-fitting quality of the oil pump bushing can be effectively evaluated and continuously optimized to avoid the occurrence of after-sales quality incidents.
