Problems solved by technology

Compared with tolerance matching and functional inspection, which rely more on the experience of designers, appearance quality is based on enterprise or project specification documents, focusing on the appearance of products, rarely involving the relevant content of the design itself, and paying more attention to The standardization of product digital model delivery and the integrity of content, and there are many inspection items
At present, the inspection of the apparent quality of digital models mainly relies on manual inspection, and the items to be reviewed need to be sorted out one by one. Omissions are easy to occur when parts are modified repeatedly, and the inspection quality is seriously affected by human factors.
In addition, before the official delivery of the digital model, it needs to go through the process of design, proofreading, review and approval, and the apparent quality inspection needs to be carried out every time. Time cost rises

example 1

[0039] An implementation method for automatically checking the apparent quality of digital models of parts, using the secondary interface provided by CATIA software, developing an automatic inspection tool based on VB program, and modularizing the appearance quality inspection according to the selected project template and part type content and execute the inspection program, and manage the results of the apparent quality inspection of the digital model of the part through the standard data set checklist.

[0040] The automatic inspection tool includes a client and a browser. The client is a basic input menu. The browser end is a three-dimensional dataset checklist. The automatic inspection tool for the apparent quality of the digital model of the part is independent of CATIA software and will not be limited by the CATIA version. It consists of a client, a program inspection module and an inspection output module.

[0041] The client is used to define the basic input require...

example 2

[0049] open first Figure 4 Corresponding to the digital model of the part to be inspected; then start the apparent quality automatic inspection tool, configure the basic input menu, select the project template and part type, and click OK to run the apparent quality inspection program. The tool starts to check the apparent quality of the part, completes 50 checks and gives the time required for the check. Finally, the tool prompts the user to select the 3D dataset checklist corresponding to the part type as the check result output file.

[0050] Such as Figure 5As shown in , the apparent quality inspection results are output to the 3D data set check list corresponding to the part, and the inspection results related to the apparent quality are automatically marked, and the cause of the error is analyzed, and combined with the results of other non-apparent quality inspection items ( Such as functionality, tolerance matching requirements, etc.), which can quickly reflect the c...

Abstract

The invention relates to a method for automatically checking the apparent quality of a digital model, belonging to the field related to the design of aircraft parts. According to the industry standardin aircraft field, Enterprise standards or user-defined project management regulations, the selection of apparent quality inspection items, the use of CATIA open secondary development interface to form a part of the surface quality automatic inspection tools, aircraft parts CATIA surface quality of the rapid inspection and inspection results output management. The method realizes modular management and has the advantages of wide application range, simple maintenance and high inspection efficiency.

Description

technical field [0001] The invention relates to the field of aircraft parts design, specifically, a method for automatically and quickly checking the apparent quality of CATIA digital models of aircraft parts according to industry standards or guidance documents formulated by enterprises. Background technique [0002] At present, domestic aircraft development projects all use digital product definition ("DMU") CATIA digital model to design parts. The design quality of CATIA digital model is usually controlled by 3F (Function, Fit tolerance, Form appearance quality) principle. The apparent quality reflects the delivery status of the part from the design department to the production department, covering the general requirements of the 3D model (such as configuration, template, display and color, etc.), and the general requirements of the part (such as entity status, activation status of geometric elements, external reference links Status, etc.), MBD general labeling requireme...
