飞机装配数控柔性多点工装技术及应用

型架是飞机装配的重要工艺装备,为了改变传统飞机装配中一个壁板组件对应一个刚性型架的"一对一"装配模式,减少工装数量,实现数字化柔性装配,提出了一种"卡板定位支点可重构"的数控柔性多点型架的新方法.详细介绍了其基本原理及设计关键技术,利用现场总线技术实现了卡板定位支点的数控调形重构,基于CATIA软件二次开发技术开发了调形计算软件,实现了数控柔性多点型架应用过程中调形数据的全数字量传递.应用表明数控型架运行稳定、可靠,满足精度要求,实现了飞机装配工装的数字化和柔性化,对飞机数字化装配柔性工装技术的研究具有重要意义.

Numerical control reconfigurable compliant tooling technology and application in aircraft assembly

Jig is an important process tooling in aircraft assembly. In order to change the traditional “one to one” assembly mode that one rigid jig only assembles one panel components in aircraft assembly, reduce the number of tooling and develop digital flexible assembly, NC(numerical control) reconfigurable compliant jig that contour board location point is reconfigurable was developed. Its fundamentals and key technologies in design was introduced. Field bus technology was used to make contour board location points numerically reconfigurable. Based on the redevelopment of CATIA, special software to compute reconfigurable data was developed. A whole digital transfer of reconfigurable data was brought about in NC jig application process. The application in practice indicated that NC jig worked stably and reliably as well as meeting accuracy requirements. The aircraft assembly jig was digitalized and flexible, which is of great significance for further study in flexible tooling technology in aircraft digital assembly.
