Carbon fiber composite materials are rather widely used in the aviation manufacturing field,and problems such as wire splitting and harmful dust caused by composite material assembly are also increasing.In response to these problems with consideration on the structural characteristics and process flow of aircraft profile components made of variable curvature composite material,this paper introduces a set of digital flexi-ble assembly production line based on automatic drilling and riveting technology that is designed,installed and debugged in the process.This production line has the functions of completing complex process tasks such as hole making,nesting,nail feeding,glue dipping and riveting,and has been applied and verified on a cer-tain type of aircraft.
