ABSTRACT:
A workpiece pick-up and positioning tool or apparatus and, more particularly, a jig and fixture arrangement facilitating the controlled movement and positioning of a workpiece in order to enable the specific treatment thereof. The workpiece, particularly, such as an aircraft inlet duct, is moved to a pick-up jig inlet tool arrangement from an assembly jig whereby the inlet duct is then inserted into and supported by a cradle. The cradle, in turn, is supported above the floor by at least two workstands whereby one of the workstands is equipped with a swivel attaching and joining the workstands to the cradle. A specific linear motion device is then adapted to tilt the cradle upwardly and into a vertical position, thereby concurrently pivoting the duct supported therein into a similar position, whereupon latching mechanisms locks the cradle into the vertical position through the intermediary of a suitable cable which is coordinated with the movement of the cradle.
