The Extraction of Product Assembly Feature Information for Intelligent Assembly Sequence Planning

The assembly feature information contained in the CAD model of the product is an important basis for the generation of intelligent assembly sequence. Taking the assembly model of the product as the research object, the research on the acquisition of assembly feature information of the product by intelligent assembly sequence planning is proposed in this paper. Microsoft Visual Studio 2005 and SolidWorks API are used as implementation means to access the internal data of the product CAD model and realize the extraction of the hierarchical information, mating relation and mating line and surface assembly features of the assembly model. An application example of product assembly feature information extraction for the locking device of an elevator landing door shows that the established method of acquiring product assembly feature information is effective and provides a theoretical and technical basis for the establishment of product design and assembly sequence planning knowledge base.
