Aviation wire harness end laser processing equipment

Abstract

The invention provides an aviation wire harness end laser processing equipment, and relates to the field of aviation wire harness processing. The equipment comprises a bottom plate, a wire clamping mechanism, a rotating mechanism, a laser mechanism and an optical system arranged in the rotating mechanism, wherein the wire clamping mechanism, the rotating mechanism, and the laser mechanism are arranged on the bottom plate in sequence. Laser is adopted for machining the aviation wire harness end, an optical system is driven by a rotating mechanism to surround a machined aviation wire harness byone circle mainly based on a nanosecond short-pulse laser with the wavelength of 405 nm, and high-precision and high-efficiency aviation wire harness end machining serves as the target. And the processing of wire stripping, windowing, longitudinal cutting, regional evaporation ablation and the like of the aviation wire harness end is realized. According to the invention, the wire taking PTFE and PVC as insulating materials is taken as a processed material, the processing time is less than 5s, the fixed-length precision is not more than 0.2 mm, the processing length is 3-30mm, and the wire coreV is physically damaged, so that the equipment is compact in structure, reliable in processing quality, high in processing efficiency, high in processing precision, small in occupied space and convenient to move.

Description

technical field [0001] The invention relates to the technical field of aviation wire harness processing, in particular to a laser processing equipment for the end of aviation wire harness. Background technique [0002] As a bridge for power supply and communication systems, the wiring harness is inseparable from the effective connection of any electronic system and communication equipment. According to statistics, for a certain type of aircraft in my country, there are more than 14,000 wires on an aircraft, so the processing amount of wire harness ends is close to 30,000. In the wire harness assembly process, wire end processing is an essential part of the assembly process, and the quality of wire end processing is directly related to the reliability of product quality. At present, in the processing of automotive wire harnesses, large-scale wire harness manufacturers widely use wire harness end production equipment that integrates fixed-length cutting, automatic wire stripp...

AI Technical Summary

Problems solved by technology

[0003] At present, some manual tools for cold stripping processing are widely used for the processing of aviation wire harness ends, such as wire strippers, special knives and other tools. This manual processing method may cause physical damage to the wire core and reduce the strength of the wire. Mechanical strength, which affects the service life of the wire, has been unable to meet the needs of the rapid development of the modern aircraft manufacturing industry

There are also some enterprises and research institutions at home and abroad to carry out research work in this area, such as using electric heating for terminal processing, but because the insulation layer of aviation wires is high temperature and low temperature resistant wires, it is not easy to be melted, after melting It is not easy to be separated, and the processing effect is not good
