Assembly visualization process design method

Abstract

The invention relates to an assembly visualization process design method, and solves problems existing in a traditional computer aided assembly process design technology. On the basis of a MPMS (Manufacture Process Management System), a unique assembly visualization process design system is developed; on the basis of the system, through an open interface, the system is integrated with a CAD (Computer Aided Design) modeling system, an assembly simulation analysis system, a product data management system and a typical knowledge base through a multi-system integration way. The integrated system has the following main functions of planning and designing the assembly process, carrying out weight reduction and storage on a three-dimensional process model, carrying out simulation verification and optimization on an assembly course, integrating a process resource base, a three-dimensional model base and a typical process resource base, and carrying out electronic countersigning and visual holographic releasing. Through assembly visualization process teaching, the design intention of the assembly process can be visually and clearly embodied, so that the assembly efficiency of assembly workers can be improved, phenomena including assembly missing and wrong assembly can be inhibited, and product assembly quality can be greatly improved.

Description

technical field [0001] The invention relates to a visual assembly process design method, which belongs to the field of assembly process design. Background technique [0002] Assembly is the most important key link in the whole life cycle of product manufacturing, which consumes a lot of time and energy, and it is also the last link for the product to obtain overall performance. The development of assembly technology is one of the decisive factors to ensure product quality and improve production efficiency. Although the computer-aided assembly process design technology has been applied at present, the reason for its own positioning is the lack of systematicness, pertinence and integration. As a result, the assembly process design generally adopts a two-dimensional model, and the process design is completely dependent on the unique expression design. The intended two-dimensional diagram is limited by its expressiveness, and a lot of energy of the craftsman is wasted in the mu...

AI Technical Summary

Problems solved by technology

[0003] 1. At home and abroad, there is no system completely designed for assembly visualization process. The current popular 3D CAD mostly starts from the perspective of product design. It lacks necessary data and technical support for how to participate in the production process and guide production. It is impossible to integrate the assembly process, The assembly parts and the manufacturing resources related to the assembly process are closely combined to realize the simulation of the assembly process and the verification of the assembly process, and it is difficult to use existing knowledge and experience

Moreover, the existing digital assembly system focuses on assembly process simulation and assembly feasibility verification, but has little consideration for the expression, generation and on-site teaching of assembly process, and cannot make full use of the process information generated in the digital assembly process to quickly generate guidance Process documentation for assembly production

[0004] 2. Low degree of optimization

Although experienced process designers can design a feasible assembly process specification, it is often not the best. Due to the limitations of personal experience and comprehensiveness and correctness of the problem, it is difficult to obtain the optimal design, which makes the process planning lack of system. sex and science

[0005] 3. Low design efficiency

As assembly process designers need to do a lot of calculations, look-up tables, and document preparation, it will take a lot of time and affect the production cycle of the product

[0006] 4. Poor consistency

During process design, it is necessary ...
