    • 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.
    • 本发明涉及用于飞机结构的自动紧固的便携式方法。 本发明将采用两个主要元件来定位和安装通过皮肤的紧固件。 内部和外部单元通过已经通过结构预钻孔的协调孔而附接到机身上并彼此分离。 飞机结构通过对准相邻的机身部件并插入对准销,与预钻孔的协调孔组装。 定位销将提供一定程度的夹紧力,将零件拉到一起,并为内部和外部真空附件履带系统提供分度。 本发明被设置为沿轨道系统横向移动,精确地定位自身,仅钻孔或锪孔,插入紧固件,并固定,即压住铆钉,或者沿着螺纹螺母倒下,然后将其自身重新定位到下一个紧固件 位置并重复该过程。
