Method for quickly compiling aircraft assembly process file

Abstract

The invention belongs to the technical field of aircraft assembly process file compilation. The invention discloses a method for quickly compiling an aircraft assembly process file. The method includes the steps: integrating CAD software provided with a customized CAD tool with a CAPP system, using a customized CAD tool to extract three-dimensional model information of a product, enabling the three-dimensional model information to form an XML process text according to a standard process parameter format, then importing the XML process text into a CAPP system, and achieving transmission and interaction of the process information. According to the method, manual extraction of the three-dimensional model information of the product from CAD software can be omitted, and automatic import of theextracted three-dimensional model information of the product can be realized, so that the compiling efficiency and quality of the assembly file are effectively improved.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing, in particular to a method for rapidly compiling aircraft assembly process documents. Background technique [0002] CAPP refers to the use of computer software and hardware technology and supporting environment to formulate the machining process of parts by using the computer's functions of numerical calculation, logical judgment and reasoning; generally understood, CAPP is to complete the process design process and generate process documents through computer assistance . The CAPP system can realize the automatic statistical summary of process information and provide convenient operation. It is an efficient tool for process documentation; [0003] At present, many professional CAPP systems have been produced in the field of parts machining. Most of these systems establish expert systems. Through reasoning and analysis of different parts processing knowledge, they assist craftsmen i...

Problems solved by technology

With the deepening of people's understanding, the application of CAPP has gradually expanded from simple mechanical processing technology design to assembly technology, heat meter technology, welding technology and other fields. However, in the field of aircraft manufacturing, due to the complexity of the aircraft assembly process, it is difficult to form Effective assembly process knowledge base to plan the assembly process and quickly form assembly process documents

[0004] With the development of CAD technology, various 3D software such as UG and CATIA are constantly emerging; on the one hand, these software provide convenience for product designers, enabling them to change traditional two-dimensional drawings into three-dimensional models; on the other hand, they also provide two-dimensional The newly developed interface meets different needs; domestic and foreign aviation manufacturing enterprises have carried out a lot of research on the assembly process based on the 3D model, and the results are mainly reflected in the realization of the assembly process with the help of CAD software, simulation software, lightweight software, and CAPP system. The simulation and visualization in the design process enrich the content of the assembly process documents, change the traditional text narrative assembly outline into a three-dimensional form of "text + animation", and can send the process design results to the on-site operator for easy operation It is easy for readers to understand the process design intent; however, the text compilation method for assembly process documents has not changed substantially, and the process personnel still need to use CAD software to open the 3D model, and then copy and manually copy and paste the data obtained in the 3D model. Assembly drawing number, assembly notes and other information are combined into the text of the assembly process file according to a certain logic in CAPP
