ABSTRACT:
A mandrel segment loader provides a reliable means of assembling the segments of a large multi-piece mandrel designed for the lay-up of composite materials in the manufacture of large structures such as one-piece fuselage barrels for wide-body aircraft and can also be used for removing the mandrel from the finished fuselage barrel by disassembling the segments. The mandrel segment loader provides transport and multi-axis positioning for the segments, which may weigh as much as 25,000 pounds, with linear positioning resolution in the realm of 0.002 inch and rotational positioning resolution in the realm of 0.005 degree. The mandrel segment loader is also more generally useful as a material handling system that can perform many useful manufacturing functions, such as loading passenger floors into a fuselage barrel when assembling an aircraft. Self-locking grippers prevent accidental self-release of a load.
