摘要:
A production system for manufacturing a workpiece comprises an index system including a plurality of index devices removably mounted on the workpiece at known longitudinally spaced locations therealong, and a longitudinally extending index member releasably engaged with at least two of the index devices such that a position and orientation of the index are fixed relative to the workpiece by the index devices, the index member having position-indicating features distributed therealong. The production system further comprises a machine module mounted for longitudinal movement along the index member and operable to perform an operation, the machine module being operable to detect the position-indicating features on the index member and thereby determine a position of the machine module relative to the workpiece.
摘要:
The present invention relates to a portable process for automated fastening of aircraft structures. The invention will employ two primary elements for locating and installing through-the-skin fasteners. Inside and outside units are attached onto an airframe and indexed to each other through coordination holes that have been pre-drilled through the structure. The aircraft structure is assembled with the pre-drilled coordination holes by aligning adjacent airframe parts and inserting alignment pins. The alignment pins will provide a degree of clamping to pull the parts together and provide indexing for inside and outside vacuum attachment track systems. The invention is equipped to traverse along the track system, accurately position itself, and drill only or countersink a hole, insert a fastener, and fasten, i.e., upset a rivet, or run down a threaded nut, then reposition itself to the next fastener location and repeat the process.
