【摘要】：自动钻铆技术在飞机制造过程中的应用,经过四十多年的发展,已被广泛应用于世界各大航空制造企业,技术比较成熟。国外航空制造企业对自动钻铆核心技术一直处于封锁状态,虽然这些年我国航空制造企业经过不断的努力,自动钻铆技术有了较大突破和进步,如自动钻铆技术在ARJ飞机机翼装配过程中的应用,但在大型民机自动钻铆技术较为薄弱,特别是在大型民机机翼自动钻铆技术方面。本论文结合我国自主研制大型民用客机C919飞机自动化、数字化、高精度化及长寿命的研制需求,对单侧翼展17m的机翼壁板在G86自动钻铆机上装配连接结构进行了具体工艺分析,确定了C919飞机机翼壁板在G86自动钻铆机13m托架上的定位装夹方式,编制和优化C919飞机机翼上壁板在G86自动钻铆机上的钻铆程序,规划了适合C919飞机机翼壁板自动钻铆工艺参数数库建立方式,提出了针对C919壁板I型和J型结构长桁偏心下铆砧应用方案。通过C919飞机17m机翼上壁板试验件在G86自动钻铆机上的两次定位、加工的实际操作,实现了在G86钻铆机13m小围框上铆接17m大壁板的定位方法,突破了小围框定位加工大壁板难点,完成了机翼上壁板在G86自动钻铆机上钻铆程序的验证和优化,建立了6种规格铆钉、12种不同厚度壁板的自动钻铆工艺参数数据库,验证了I型和J型结构长桁偏心下铆砧的使用方案,解决了C919飞机17m机翼壁板自动钻铆的关键技术难题。
[Abstract]:The application of automatic drilling and riveting technology in the aircraft manufacturing process has been widely used in aviation manufacturing enterprises in the world after more than 40 years of development, and the technology is relatively mature. Foreign aviation manufacturing enterprises have been blocking the core technology of automatic drilling and riveting, although our aviation manufacturing enterprises have made great breakthrough and progress in automatic drilling and riveting technology through continuous efforts in recent years. For example, the application of automatic drilling riveting technology in ARJ aircraft wing assembly process, but in the large civil aircraft automatic drilling riveting technology is relatively weak, especially in the large civil aircraft wing automatic drilling riveting technology. In this paper, according to the requirement of automatic, digital, high precision and long life development of the C919 aircraft, the connection structure of the wing panel with a single wing span of 17 m on the G86 automatic drilling riveting machine is analyzed. The positioning and clamping mode of wing panel of C919 aircraft on the 13m bracket of G86 automatic drilling riveting machine is determined, and the program of drilling and riveting on the wing panel of C919 aircraft on G86 automatic drilling riveting machine is worked out and optimized. The method of establishing automatic drilling and riveting process parameter library for C919 aircraft wing panel is planned. The application scheme of C919 panel I and J structure long truss eccentric riveting anvil is proposed. Through the twice positioning and machining operation of the test piece of the upper wall plate of the 17m wing of C919 aircraft on the G86 automatic drilling and riveting machine, the positioning method of riveting 17m large wall plate on the 13m small frame of the G86 drill riveting machine is realized, and the difficulty of the small frame positioning and machining the large wall plate is broken through. The verification and optimization of the riveting procedure for the upper wing panel on the G86 automatic drilling and riveting machine is completed, and the database of automatic drilling and riveting process parameters of 12 different thickness wall plates of 6 kinds of rivets is established. The application scheme of I type and J type long truss eccentric lower riveting anvil is verified, and the key technical problem of automatic drilling and riveting for 17 m wing panel of C919 aircraft is solved.
