    • An end effector (50) provides one up assembly drilling through mated components, including a panel, by preloading the components to assure interface integrity, thus avoiding subsequent separation for cleaning and deburring. The end effector (50) includes a drill and clamp dispenser for temporarily inserting and removing expansible single-sided clamps at various pre-drilled locations in the panel. In one method, pilot holes (28) are first pre-drilled into mated components, for example an aircraft wing panel and a wing rib or spar; an initial pilot hole location is identified, and an expansible clamp (60) is inserted into a pilot hole adjacent a desired initial fastener hole (40) location. The clamp is torqued, causing its expansion for preloading the wing panel and rib and/or spar components under a predetermined load. The fastener hole (40) is then drilled, the end effector (50) untorques and removes the clamp and identifies a second (and/or next) pilot hole location, and the process is replicated.
    • 末端执行器(50)通过预先加载部件以确保界面完整性,从而避免随后的分离以进行清洁和去毛刺,从而通过配合部件(包括面板)提供一次向上组装钻孔。 末端执行器(50)包括钻头和夹具分配器,用于在面板中的各种预先钻出的位置处暂时插入和移除可膨胀的单面夹具。 在一种方法中,先导孔(28)首先被预先钻入配合部件,例如飞机机翼面板和翼肋或翼梁; 识别初始导向孔位置,并且将可扩张夹具(60)插入邻近期望的初始紧固件孔(40)位置的导向孔中。 扭转夹具,引起其扩张,以在预定载荷下预加载翼板和肋和/或翼梁部件。 随后钻出紧固件孔(40),末端执行器(50)松开并移除夹具并识别第二(和/或下一个)导向孔位置,并且该过程被复制。
