Automated Removal of Temporary Fasteners on Wing Panels

Current practice for assembly of wing skins to wing stringers utilizes temporary aluminum lock bolts prior to squeeze riveting. Removing and replacing these fasteners is time consuming and hazardous. We have automated the wing riveters to perform this replacement process. This paper discusses the four areas of development that were carried out to accomplish this: tack fastener installation, machine vision system development, drill development and new tooling. Testing results and new findings will be discussed.

Analysis & Modeling Reduce Development Risks For Improving Integration of Large Aircraft Components

Historically the manufacturing of aircraft fuselages with capacities of 100+ passengers requires large panels and assemblies to be integrated through processes of manipulating them into proper alignment to one another, and then fastening the panels and assemblies together. The manipulating and alignment processes typically incorporate large handling devices and cranes to move the large panels and monolithic tools or measurement alignment systems to precisely align the aircraft components. After the individual panels and assemblies are properly aligned, they can be fastened together. Normally, the fastening process is performed manually with the aid of fastener location templates. There are problems with these processes. They require high capital investments for tooling and facilities; up to two shifts (16 hours) to complete the loading, indexing, and fastening operations; and depend on a highly skilled and knowledgeable work force to minimize discrepancies.
