Titanium alloy skin laser cutting method based on flexible supporting device

Abstract

The invention provides a titanium alloy skin laser cutting method based on a flexible supporting device. According to the method, the flexible supporting device and a five-coordinate laser cutting machine are used in cooperation for cutting titanium alloy parts, not only is the problem that because the titanium alloy skin parts can not be tightly attached to a clamp, the part cutting precision is influenced solved, but also the problems that because the allowance portions of the titanium alloy skin parts can not be supported, the parts are prone to vibrating in the part falling process, and the cutting quality of the edges of the parts is poor are solved. Meanwhile, the flexible supporting device is universal, and the defects that existing special tools are various in variety and number, large in size and occupied inventory area and high in cost are overcome.

Description

technical field [0001] The invention relates to the field of processing aircraft titanium alloy skin parts, in particular to a laser cutting method for titanium alloy skin parts based on a flexible support device. Background technique [0002] The design of aircraft zigzag titanium alloy skin puts forward higher requirements for the edge quality and precision of parts. Traditionally, laser cutting fixtures are used for laser cutting of parts. However, in actual production, due to factors such as high rigidity of titanium alloy parts and tooling manufacturing errors, etc. , the part and the fixture cannot be tightly fitted, which affects the cutting accuracy of the part; at the same time, there is no support for the spare part of the part, which may easily cause the part to vibrate during the falling process, resulting in poor cutting quality of the edge of the part, which cannot meet the inspection requirements, and a large number of subsequent manual trimming The work great...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems and deficiencies in the prior art, the present invention provides a titanium alloy skin laser cutting method based on a flexible support device, which uses the cooperation of a flexible support device and a five-coordinate laser cutting machine to cut titanium alloy parts, It not only solves the problem that the titanium alloy skin part and the fixture cannot be tightly fitted, which affects the cutting accuracy of the part, but also solves the problem that the remaining part of the titanium alloy skin part is unsupported, and it is easy to cause the part to vibrate during the falling process, resulting in the edge of the part The problem of poor cutting quality. At the same time, the flexible support device has versatility, which avoids the defects of the existing special tooling such as a large number of types, large volume, large inventory area, and high cost.
