ASSEMBLY METHOD AND ASSEMBLY APPARATUS FOR MANDREL USED IN PRODUCTION OF COMPOSITE MATERIAL STRUCTURE

摘要

Disclosed is a technique that can easily assemble, with high positional accuracy, a mandrel that is used, for example, in the production of an aircraft body, or the like, and has a roughly cylindrical structure that is dividable into a plurality of segments. In a segment fixing process, one of the aforementioned segments, which is the target of fixing, is fixed in one specified fixing point from among fixing points that are configured in plurality along a pair of facing support rings. In a rotating process, the aforementioned support rings are rotated before the segment fixing process in a manner such that the aforementioned specified fixing point is positioned on the top part of the support rings. Here, in the aforementioned segment fixing process, the segment to be fixed is disposed between each of the aforementioned support rings, and after being raised vertically to a height corresponding to the specified fixing point, is fixed to said support rings.
