Assembling method of mandrel used for manufacturing composite material structure and assembling apparatus of mandrel

摘要

A technique which can assemble a mandrel having a substantially cylindrical shape and being dividable into plurality of segments, which is used for manufacturing, for example, a fuselage of an aircraft, with high position accuracy and an easy manner. In a segment fastening step, a segment which is a fastened target is fastened to a specified fastening portion which is one of a plurality of fastening portions set along a pair of support rings placed to face each other. In a rotation step, before the segment fastening step, the support rings are rotated so that the specified fastening portion is located at an uppermost portion of the support rings. In the segment fastening step, the segment which is the fastened target is placed between the support rings and lifted vertically up to a height corresponding to the specified fastening portion and then fastened to the support rings.

主权项

1. An assembling apparatus of a mandrel for use in assembling of a tubular mandrel by joining a plurality of segments together, the mandrel being supported by a pair of support rings facing each other, the segments having a substantially rectangular shape and being parts into which the mandrel is divided along a center axis direction, in which
a plurality of fastening portions of the segments are set along a circumferential direction on each of the pair of support rings, the assembling apparatus comprising: a rail body inserted into a hollow space of the pair of support rings; a ring rotation drive section for rotating each of the support rings to position at an uppermost portion of each of the support rings a specified fastening portion which is one of the fastening portions set on the pair of support rings; a horizontal movement mechanism which is provided on the rail body and configured to horizontally move the segment from a rear end of the rail body toward a tip end of the rail body; and a vertical movement mechanism which is provided on the rail body and configured to lift up the segment moved from the horizontal movement mechanism to a height position corresponding to the specified fastening portion along the vertical direction, to fasten the segment to the specified fastening portion.
