The invention provides a three-dimensional digitization final assembly technology collaborative design system which at least comprises a final assembly technology data management module, a final assembly technology process management module, a final assembly technology personnel organizational management module, a final assembly technology authority management module, a final assembly technology collaborative design module, a final assembly technology simulation and verification module and a final assembly technology data dissemination module. Through secondary development and software implementation, the three-dimensional digitization final assembly technology collaborative design system establishes an integrated three-dimensional digitization collaborative environment by taking data management as a core, and enables the product three-dimensional model to be fully shared and used on various business links of a whole enterprise; distributed data and document collaborative management is realized, through the research of a process management method of a product cross-domain collaborative design manufacturing business process, the product is enabled to be subjected to quick seamless integration from design to technology, the lead time of the product is effectively reduced, and the three-dimensional digitization of the design and manufacture is realized.

Description

technical field [0001] The invention relates to a system in the field of computer integrated manufacturing, in particular to a three-dimensional digital assembly process collaborative design system. Background technique [0002] Assembly process design is the main content of product assembly design, which solves the problems of product parts assembly sequence, assembly path, assembly process method, tools and fixtures used. The traditional assembly process design is manual preparation, which has problems such as long preparation cycle, excessive reliance on the technical level and assembly experience of craftsmen, and cumbersome and irregular assembly process design. With the successful application of Computer Aided Process Planning (CAPP) technology in parts processing design, Computer-Aided Assembly Process Planning (CAAPP) is an effective tool to solve product assembly process planning problems. Also conceived. [0003] The current computer-aided assembly process planni...

Problems solved by technology

[0004] (1) It is difficult for two-dimensional CAD to express complex product structures and surface shapes. The basic elements of its graphics are points, straight lines and curves. It is difficult to quickly obtain accurate product feature information from the topology of these basic elements; based on two-dimensional It is difficult to express, generate, organize and manage the assembly process design knowledge of the view, and cannot effectively summarize the design experience and design methods;

[0005] (2) Complicated products and parts can only be displayed in two-dimensional view, which requires high drawing ability of assembly operators; it is difficult to fully express the key features of parts in two-dimensional view, and it is difficult to understand, which is easy to increase due to erroneous recognition. The number of waste products caused by the drawing; the evaluation and review of the performance of the assembly process cannot be effectively carried out, or it is a mere formality;

[0006] (3) Insufficient collaboration between design and process. Design results are mainly distributed to the manufacturing department in the form of 2D drawings supplemented by 3D models. Due to the lack of manufacturing information such as tolerance dimensions, product 3D models cannot replace 2D drawings. It is used for process design and manufacturing; at the same time, the participation and feedback of the process to the design is also very limited, and the feedback is often given after problems are found in the actual production;

[0007] (4) When the problem of design change occurs, the two-dimensional process design needs to be handled by telephone, paper change order, etc., and the degree of coordination of the design process is low. At the same time, it is accompanied by a large amount of paper waste, which is contrary to the paperless production advocated by the aerospace industry

[0012] To sum up, the current 3D assembly process planning system only emphasizes the use of 3D data in assembly process planning, and lacks the management functions of data management, personnel management, process management and other management functions required for the whole process of 3D digital assembly process design. Realize the connection of 3D data from the design department to the process department and then to the on-site assembly
