Rapid generation method of aircraft conduit processing files

Abstract

The invention provides a rapid generation method of aircraft conduit processing files. The rapid generation method includes the steps of 1) extracting conduit PRB (axial elongation, rotation angle, bending angle) data; 2) adding process allowance; 3) calculating coordinates of key points of process information; 4) performing a process examination based on knowledge; 5) performing the simulation interfering; 6) generating the processing file. The rapid generation method has the advantages such as accurate recognition and high speed, can be applied to process program analysis and design and development of digital process system of the aircraft conduit and has a bright application prospect.

Description

technical field [0001] The invention relates to a method for quickly generating aircraft duct processing files, which belongs to the technical field of aircraft digital advanced manufacturing. Background technique [0002] Piping systems such as hydraulic pressure, fuel, environmental control, and oxygen inside the aircraft are inseparable from various conduits. The traditional conduit manufacturing usually adopts the production method of bending, manufacturing and testing according to the actual sample after obtaining the actual sample on the aircraft. This manufacturing method requires that every time a new type of aircraft is produced, a considerable number of conduit standard samples, bending fixtures and surface inspection fixtures must be manufactured and stored. With the continuous increase of new models, the rapid increase of catheter standard samples and various fixtures and tools not only brings difficulties to inventory storage and management, but also transfers t...

Problems solved by technology

With the continuous increase of new models, the rapid increase of catheter standard samples and various fixtures and tools not only brings difficulties to inventory storage and management, but also transfers the manufacturing basis through the analog quantity of real samples, which will also make the production of catheters difficult. quality not guaranteed

[0003] As new models gradually use 3D digital models as the production basis, craftsmen need to conduct process review on design digital models in the early stage, and process review of design digital models requires craftsmen to manually measure and compare design digital models one by one. Large quantities are prone to review errors. At the same time, because the designer cannot consider the production capacity and processing process of the production equipment in advance when designing the digital model, the craftsman cannot simulate the specific processing process during the process review, and the design digital model cannot be determined. Whether there will be interference in the production process, the review of the design digital model can only be done roughly, without accuracy, which will have a serious impact on the later production cycle; Manually extract design data and modify it to form production data. The operator needs to manually input the production data into the pipe bender for pipe bending. If there is a mistake in this series of data conversion and input process, it will directly lead to the final product. scrapping, which affects the manufacturing quality and production cycle of the aircraft
