摘　　要：过盈零件压力装配控制,直接影响到发动机自动化装配的质量。提出了采用数字化伺服电动压缸控制系统替代液压控制系统的发动机压装控制方案,设计了基于EtherCAT的汽车发动机数字化闭环控制伺服压装专业化数控系统的软硬件结构。采用伺服电动压装专业化数控系统,实现了压装过程的全数字化全闭环控制。该系统具备高精高效,节能环保,柔性可配置、可重构、可扩展特点。The press-fit control of interference parts will directly influence on the quality of automatic assembling of engine. The paper presents a press-fit control method of engine that adopts the control system of digital servo electric pressure cylinder instead of the control system of hydraulic , and designs a software and hardware structure of the specialized digital closed-loop servo press-fit control system for auto engine, which is based on EtherCAT. The use of servo electric press-fit specialized numerical control system implements full digital and full closed-loop control. The characteristics of the system are high precision and high efficiency, the energy-conservation and environment-protection and flexibility which is able to confizure, reconstruct and exnand.
