Single-driving composite material fiber placement head integral device and reconveying wheel shaft system thereof

Abstract

The invention belongs to the technical field of composite material automatic placement forming, and particularly provides a single-driving composite material fiber placement head integral device and areconveying wheel shaft system thereof. The problem that an existing single-driving composite material fiber placement head integral device is poor in placement quality in the corner placement or variable curvature curved surface placement process is solved. The reconveying wheel shaft system comprises a transmission shaft and a plurality of unidirectional wheel devices; each unidirectional wheeldevice comprises an inner ring coaxially fixed to the transmission shaft, and an outer ring matched with a reconveying wheel device; the outer rings are coaxially connected with the inner rings; andconnection between the outer rings and the inner rings are arranged to enable the outer ring to freely rotate relative to the inner rings unidirectionally. The single-driving composite material fiberplacement head integral device provided with the reconveying wheel shaft system can allow that the placement path lengths of multiple fiber beams and the placement speed of the multiple fiber beams are different, the placement tension stability of each fiber beam is kept, and the placement quality is improved.

Description

technical field [0001] The invention belongs to the technical field of composite material automatic laying and molding, and specifically provides a single-drive composite material laying head integrated device and a re-feeding axle system. Background technique [0002] Composite materials have the advantages of high specific strength, high specific modulus, fatigue resistance, good vibration damping, and good manufacturability. These advantages are of great value to the performance of aircraft and have been widely used in the aerospace industry. At the same time, in other industries, such as sports equipment, ships, high-speed rail and other fields, the amount of composite materials is also increasing. [0003] Composite monolithic components with high curvature profiles, such as aircraft fuselage sections, and other elliptical heights such as jet engine cowlings, intake ducts, nozzles, conical tubes, compressor blades, circular or "C" shaped channel tubes, etc. For integra...
