    • One advantageous embodiment of the present invention is an integral clamping-and-bucking apparatus (12) for a system (10), which is utilized for applying rivet fasteners (56) to two or more panels 14a, 14b) and forming a joint (24) therebetween. The integral clamping-and-bucking apparatus (16) includes a clamping foot (46) for clamping the panels (14a, 14b) in a predetermined configuration and for drilling a hole (54) in the panels (14a, 14b) the panels (14a, 14b) at the joint (24). Also, the integral clamping-and-bucking apparatus (12) further includes a bucking bar (48) for bucking a rivet tail (62) that extends from the hole (54). The clamping foot (46) and the bucking bar (48) are coupled to and actuated by a controller (32). This controller (32) actuates the bucking bar (48) and the clamping foot (46) for transferring power between the clamping foot (32) and the bucking bar (48) while maintaining a substantially constant total force applied to the panels (14a, 14b).
    • 本发明的一个有利实施例是用于系统(10)的整体夹紧和弯曲装置(12),其用于将铆钉紧固件(56)施加到两个或更多个面板14a,14b)并形成接头 24)。 整体夹紧和弯曲装置(16)包括用于将面板(14a,14b)夹紧在预定构造中并用于在面板(14a,14b)中钻孔(54)的夹紧脚(46) 14a,14b)在接头(24)处。 而且,整体夹紧和弯曲装置(12)还包括用于弯曲从孔(54)延伸的铆钉尾部(62)的弯曲杆(48)。 夹紧脚(46)和反作用杆(48)联接到控制器(32)并由控制器(32)致动。 该控制器32在保持施加到面板14a,14b上的基本恒定的总力的同时致动补夹杆48和夹紧脚46以在夹紧脚32和补偿杆48之间传递动力。 14B)。
