摘　　要：油泵类产品是航天伺服机构上重要的动力能源元件,其密封关键零件具有高精度的表面质量检测需求。该类零件一般采用石墨合金的复合材料制成,传统的检测方法无法满足设计工艺要求。本文对密封关键件表面粗糙度和平面度的检测技术进行研究,提出光学非接触的测量方法,并对其进行测量试验及对比,分析误差产生的原因,提出相应解决方法并得到验证。该方案已经应用于实际生产,满足了产品技术的指标要求。Oil products is an important component of space power servo mechanism, the sealing surface quality detection requirements of key parts with high precision. This kind of parts usually adopts graphite alloy composite material, traditional detection methods can not meet the design requirements of the process. The key seals surface roughness and flatness detection technology research on the proposed optical non contact measurement method, were measured and compared,on the causes of errors are analyzed, put forward corresponding solutions and verified. This scheme has been used in actual production,meet the technical requirements of the product.
