Description

Technical Field

[0001] This utility model relates to the field of composite material bonding technology, and in particular to a tooling for bonding and molding wing skeletons. Background Technology

[0002] A wing frame typically consists of composite material parts such as the main beam, rear wall, and spacers, metal parts such as the wingtip and main connector, and foam. The composite material parts are individually molded and cured, and then bonded to the foam and metal parts. Currently, the composite material and metal parts require separate positioning during the bonding process, but problems exist such as jamming, inaccurate positioning, and low yield rates due to insufficient compaction of foam parts. Furthermore, the composite material cannot be inspected after molding, especially the spacers, which are molded from prepreg, resulting in inconsistent thickness and ultimately, defective bonded wing frames. Therefore, a wing frame bonding and molding fixture needs to be designed to compress the wing frame, inspect the composite material parts, and accurately position both the composite material and metal parts.
