摘　　要：由于飞机装配过程中需要钻削大量的孔,因此针对飞机装配中柔性制孔的功能需求,在具体分析机翼制孔工艺流程的基础上,设计了一套用于飞机自动制孔的末端执行器。该控制系统以中央控制器为核心、采用基于EtherCAT总线和Profibus总线的分布式主从站控制方式,并开发出具有制孔循环控制、基准检测、法向偏差测量等功能的软件包,最后进行了一台样机的制造、装配、电气安装和软件调试。实验证明,该系统能够很好的满足航空工业对制孔的孔位精度、垂直度以及加工效率等的要求。Due to numerous holes in A ircrofi assembly, a new auto-drilling end-effector was designed aiming at the demands for flexible drilling in Aircraft assembly and according to the analysis of auto-drilling flow in wing. The system regards the central controller as the core, uses the EtherCAT and Profibus fieldbus-based distributed master-slave control mode, and a software package containing a number of functions such as auto-drilling cycle , datum detection, normal measurement, etc, is developed. The prototype is manufactured,assembled and debugged at last and the experiments verified that the system can work well to meet the requirements such as position accuracy,verticality and machining efficiency in aviation industry.
