3D printing drilling template for self-adapting airplane curved surface skin drilling

Abstract

The invention discloses a 3D printing drilling template for self-adapting airplane curved surface skin drilling. The 3D printing drilling template comprises a laminating plate, a guide rail and a plurality of rib plates, the curvature of the laminating plate is equal to the curvature of airplane curved surface skin, the laminating plate is provided with a plurality of normal vector drill sleeve holes, the axial direction of the normal vector drill sleeve holes is the same as that of the normal vector of the drilling position on the airplane curved surface skin, one ends of the rib plates are fixedly connected with the laminating plate, the other ends of the rib plates are fixedly connected with the guide rail, the curvature of the guide rail is equal to the curvature of the airplane curvedsurface skin, and the guide rail is used for installing an automatic drilling robot. The 3D printing drilling template can be adaptive to the aircraft curved surface skin with any curvature, so thatthe purpose of accurate guiding and drilling is achieved, and the efficiency, precision and quality of drilling of the airplane curved surface skin are improved.

Description

technical field [0001] The invention relates to the technical field of aircraft curved skin drilling, in particular to a 3D printing drilling template for self-adaptive aircraft curved skin drilling. Background technique [0002] In the field of machinery manufacturing and automation where various hole-making technologies are developing rapidly, the corresponding hole-making requirements and levels are getting higher and higher, especially in the field of aerospace, aircraft surface skin hole making technology directly determines the domestic C919, ARJ21 and The performance of various types of aircraft such as the J-20 fighter jet bears the great responsibility of solving the important needs of the country and solving the problems of being stuck and being stuck. As the core technology of aerospace, aircraft surface skin drilling technology directly reflects the level of national aerospace. In the process of aircraft manufacturing and assembly, there are thousands of holes, ...

AI Technical Summary

Problems solved by technology

Traditional drilling templates are designed and manufactured based on machining, which has a long time period, high cost, and low interchangeability. In addition, there are many technical errors and manual errors in the manufacturing process, which cannot be self-adaptive and complex. aircraft surface skin

Moreover, the hole making of aircraft curved skin is a highly repetitive task. Using traditional drilling templates for lamination and manual hole making technology cannot guarantee the accuracy, and it will increase the difficulty of hole making when dealing with complex aircraft curved skin.
