Embodiment Construction

[0008] 1. If the target catheter needs to be manufactured have three-dimensional digital molds, imported directly into the Catia platform; if there is no three-dimensional number of models, first, the retrogractive measurement is used to obtain the digital model and then import the Catia platform;

[0009] 2. Quantitatively edit the target catheter count mode in the CATIA platform, allowing it to meet standardized design requirements or special needs of the body structure, edit the specific format data file; if the original number of model information is in line with the requirements, skip this step Import directly into the number-controlled elbow assist platform for related operations;

[0010] 3. Import data files or reverse data files output from the CATIA platform through the CNC bend intelligent auxiliary platform, quickly output a CNC bending machine processing file, and import the CNC bending machine to implement a one-button operation To make a target catheter;

Abstract

The present invention proposes a fast and accurate digital manufacturing method for aviation catheters. The method uses domestic numerical control pipe bending equipment and joint arm measuring machines, and combines the self-developed numerical control pipe bending intelligent auxiliary platform and CATIA software catheter standardization design technology to construct aviation catheters. A complete framework for fast and accurate digital manufacturing. Among them, the CNC pipe bending intelligent auxiliary platform can complete the automatic springback calculation and intelligent matching of process parameters, and realize the rapid conversion and generation from the catheter theory file to the CNC processing file; the CATIA software catheter standardized design technology is mainly used for the non-compliant CNC pipe bending process The geometric information is optimized and standardized, and the quantitative editing of non-standard data sources is realized. The rapid and accurate digital manufacturing framework of aviation conduit constructed by the present invention can not only target the standard data source of aviation conduit that has been digitally designed, but also target the non-standard data source of traditional aircraft obtained by reverse surveying and mapping, and is a large-scale and low-cost application of numerical control pipe bending technology Laid the technical foundation.

Description

Technical field [0001] The present invention relates to the field of digitized manufacturing, and more particularly to a fast and accurate digital manufacturing method for aeronautical catheter. Background technique [0002] As the modern aircraft design is more complex, its assembly accuracy requires more harsh, and the corresponding requirements for air duct manufacturing are proposed. Different from ordinary civilian catheter assembly, aviation catheter assembly belongs to a typical multi-constraint assembly, which must satisfy both end ports, but also to ensure the unstressed assembly of the catheter and the body assembly mechanism. In order to meet these requirements, on the one hand, it is necessary to improve its space toward the fitness. On the other hand, it is necessary to accurately calculate its two-end port size to ensure the quality of the interface assembly connection, which is urgently needed to use the advanced digital manufacturing technology of aviation duct. s...
