Problems solved by technology

Secondly, the positioning tooling in the current assembly method has a single function, especially the traditional frame positioning tooling, which requires workers to do a lot of manual operations, and needs to customize the assembly positioning tooling for each part, which consumes manpower and material resources, low positioning accuracy, and long production cycle. High labor intensity and poor economic applicability

Abstract

An aircraft center wing box digital assembly positioning system and positioning method are provided. A digital flexible positioning tool is divided into a bed body unit, a front spar positioning unit,a rear spar positioning unit, a left wing rib conformal unit, a right wing rib conformal unit, an upper tooling positioning pressing unit and a lower tooling positioning pressing unit according to functional modules. At first, an automatic positioning method is performed with the skeleton as the reference; skeleton parts such as the front spar, the rear spar and the wing rib of the large-scale central wing box are accurately positioned, and then the upper panel, the low panel and the longitudinal spar are positioned with the skeleton as a reference until the whole positioning process of the central wing box is completed. The digital assembly positioning system and positioning method are capable of accurate positioning, automatic control, multi-functional integration, and flexible design of large-scale center wing boxes.

Description

technical field [0001] The invention relates to a digital assembly positioning system and a positioning method of an aircraft central wing box, belonging to the technical field of aircraft manufacturing. Background technique [0002] As a key component of an aircraft, the central wing box has the characteristics of strict aerodynamic shape requirements, frequent design changes, numerous product configurations, various parts materials and shapes, complex internal structure, compact space, dense layout of various systems, and a large number of components. Its assembly is difficult and requires high assembly quality. Since the 1990s, major foreign aviation developed countries have carried out large-scale research on aircraft digital assembly technology, and developed a number of digital equipment for aircraft assembly. Due to technical blockade and other reasons, the application of domestic aircraft digital assembly is still in the stage of exploration and practice. Except for...
