Skin allowance cutting method for aircraft components or parts

Abstract

The invention provides a skin allowance cutting method for aircraft components or parts. The skin allowance cutting method includes: conforming to disassemble an assistant tool of the last procedure and homing the rest standard parts, waste and assembling tools after the aircraft components or parts are assembled; mounting an aircraft skin allowance cutting device on a tooling orbit of the aircraft components or parts; adjusting a cutting tool and cutting parameters through a route adjusting button of the aircraft skin allowance cutting device; starting the aircraft skin allowance cutting device, and completing cutting in one week. The skin allowance cutting method has the advantages that automatic cutting can be realized, cutting precision and efficiency are high, labor intensity is low, skin allowance cutting of titanium alloy can be completed and the like, and therefore, the skin allowance cutting method can be widely applied to the aircraft manufacturing field.

Description

technical field [0001] The invention relates to a cutting technology, in particular to a skin margin cutting method of an aircraft component or component. Background technique [0002] At present, in the manufacture of aircraft components or components, skin allowance cutting is an essential process, and the cutting accuracy of skin allowance affects the aircraft assembly accuracy. In practical applications, the skin allowance cutting of domestic aircraft components or parts mainly adopts manual process methods: first, use a scribe ruler to mark the line to determine the position of the cutting line; then, use pneumatic shears to remove the excess skin along the cutting line secondly, use a pneumatic milling cutter to fine-tune along the cutting line; finally, manually polish the cut surface of the skin. The process is carried out manually, and the labor intensity of workers is high, the work efficiency is low, and the cutting precision is low. For example, it takes 4 to 5...

AI Technical Summary

Problems solved by technology

This process method is carried out manually, the labor intensity of the workers is high, the work efficiency is low, and the cutting accuracy is low

For example, it takes 4 to 5 workers 5 to 7 working days to complete the skin cutting of the process separation butt joint of a medium-sized aircraft fuselage part; and for a large aircraft, since the skin thickness increases to 2.5 to 8 mm, and the large Part of the aircraft is made of titanium alloy skin, which cannot be completed by this manual process

[0003] It can be seen that the existing technology has problems such as poor cutting accuracy, low cutting efficiency and high labor intensity, and even the inability to realize titanium alloy skin cutting.
