    • A system for applying a predetermined proof load to a control cable and measuring the resultant cable length thereof includes a motor (32) which, under the control of a controller (14) drives an actuator (28) which, in turn, controllably displaces an end fixture (26). The exact distance moved by the end fixture (26) is monitored by an encoder (34) and a load cell (27) monitors actual loading on a cable under test. A home position sensor (30) provides input to the controller (14) to indicate whether or not the end fixture (26) is homed to its reference position. During cable testing, the fixed end of the cable is fixedly attached to a predetermined position in a channel (20). The free end of the cable is then attached to the end fixture (26). The controller (14) actuates the motor (32) to thereby provide a predetermined proof load profile to the cable under test. At the end of the proof loading test, the controller (14) determines, via the encoder (34), the distance L.sub.2 that the end fixture, and thus the cable have moved from the home position. This distance L.sub.2 is added to the initial distance L.sub.1 from the home position to the fixed anchor hole (23) to thereby determine an overall length L of the cable.
    • 一种用于将预定的证明载荷施加到控制电缆并测量其合成电缆长度的系统包括电机(32),其在控制器(14)的控制下驱动致动器(28),所述致动器(28)又可控地移位 (26)。 通过编码器(34)监测末端夹具(26)移动的精确距离,并且称重传感器(27)监测被测电缆上的实际载荷。 原位传感器(30)向控制器(14)提供输入以指示末端夹具(26)是否被归位到其参考位置。 在电缆测试期间,电缆的固定端固定地附接到通道(20)中的预定位置。 然后将电缆的自由端连接到端部固定件(26)上。 控制器(14)致动马达(32),从而为被测试的电缆提供预定的载荷曲线。 在验证加载测试结束时,控制器(14)经由编码器(34)确定终端固定件的距离L2,并且因此电缆已经从原始位置移动。 该距离L2被添加到从原始位置到固定锚定孔(23)的初始距离L1,从而确定电缆的总长度L.

    • An assembly cell for accurate placement of stringer clips in a channel of a stringer for a compound contour section of an airplane fuselage, and for holding the clips at a predetermined orientation while drilling holes for fastening the clips in the stringers includes a fixture having locating surfaces for holding the stringer in a configuration that is the same as the configuration it will have when installed at its designated position in the airplane. The fixture has headers adjustable to conform to the shape of the airplane in which the stringers will be installed, The headers have clamps for securing the stringers against accurately machined reference surfaces on the headers. An end effector is held by a machine tool in the assembly cell for gripping a stringer clip and inserting it into the stringer channel. The end effector has spreader bars for insertion in the stringer channel operable to spread sidewalls of the stringer and widen the channel to facilitate insertion of the stringer clip, and has clamp bars positionable on opposide sides of the stringer and operable to close on the stringer to squeeze the stringer sidewalls on the stringer clip after insertion in the channel. Opposed drills on the end effector have right angle drives holding drill bits for simultaneously match drilling holes through the sidewalls and through the stringer clip. The end effector machine tool operates as a positioning mechanism for accurately for positioning the drills at each stringer clip location along the stringer clip to positions corresponding to the contour of the fuselage at each of the locations under control of a CNC machine controller.
