Problems solved by technology

[0005] In the existing UAV technology, the composite material parts must ensure both the aerodynamic shape and the assembly accuracy. For the composite material structure of the secondary bonding and secondary assembly, the combined female mold design is generally used; because the female mold The structure is deep, the female mold of the design combination is difficult to operate, and the operating space is insufficient when laying the female mold

Abstract

The invention provides an unmanned aerial vehicle electric cabin composite cephalic cone integrated forming tool and process. The unmanned aerial vehicle electric cabin composite cephalic cone integrated forming tool comprises a male molded surface, internal square pipe supports, a blocked metal core model, a metal moving disc, internal center circular pipe supports, positioning pins, fastening bolts, demolding bolts and demolding blocks, four swivels are mounted on the outer side wall of the male molded surface, a vacuum bag area is formed in the surface of the male molded surface, the blocked metal core model sleeves the top of the male molded surface, and the blocked metal core model and the male molded surface are in positioning butt-joint through the positioning pins. According to theunmanned aerial vehicle electric cabin composite cephalic cone integrated forming tool and process, design is reasonable, the assembly accuracy can be guaranteed, it is guaranteed that secondary bonding co-curing forming of a composite cephalic cone and a motor mounting metal clamping disc meets the requirements, and meanwhile the equipment cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of UAV accessories processing, and in particular relates to an integrated molding tooling and molding process of a composite material nose cone of an UAV motor cabin. Background technique [0002] With the continuous development of aviation technology, UAV has become the focus of research in various countries. Due to its characteristics of being unmanned, long in the air, and high precision, it can be used in relay communication, monitoring, reconnaissance, surveillance, and strikes in different terrains and regions, and has broad application prospects in military and civilian fields. [0003] Advanced composite materials have the advantages of high specific strength, high specific modulus, and strong designability. Due to the requirement of lightweight, more and more aircrafts adopt composite materials. Since the use of composite materials can greatly reduce the structural weight, improve the overall perf...
