Digitized assembling supporting system and method of aero-engine parts

Abstract

The invention discloses a digitized assembling supporting system and method of aero-engine parts. The system comprises a central computer control unit, a part assembling process database, an assembling station laser-assisted orientation device, an assembling station digitalized display platform and an approach part code scanning system; after reading the code information of approach parts recognized by the code scanning system, the central computer control unit extracts corresponding parts assembling data from the part assembling process database, and respectively transmits to the laser-assisted orientation system and the digitalized display platform; the digitalized display platform repeatedly plays the assembling process procedure and assembling process simulation animation of the partsto be assembled, so as to remind on-site engineers; a laser projector projects a pointed laser beam to the installation position of the parts to be assembled on the engine assembling body; the on-siteengineers executes the on-site assembling tasks of the parts. The digitized assembling supporting system and method of aero-engine parts, the overall assembling efficiency of the aero-engine can be remarkably improved while the installation positions of the parts can be rapidly and accurately positioned.

Description

technical field [0001] The invention relates to the technical field of aero-engine digital assembly, in particular to a digital assembly support system and method for aero-engine components. Background technique [0002] Aeroengines are the core power components of aviation vehicles, and their manufacturing and assembly technology level is an important symbol of a country's scientific and technological strength, industrial strength and national defense strength. Contemporary large-scale turbofan aeroengines have high structural complexity and technical precision, and are usually assembled from hundreds of thousands of various parts through complex technological processes. [0003] Generally, a large aero-engine includes various types of small and medium-sized parts such as pipelines and brackets. There are a large number of them, various types, and different shapes, and it is difficult to quickly identify them on the actual assembly line. At present, in the assembly and pr...
