Abstract

The invention provides a fastener selection method and system, and the method comprises the steps: collecting fastener information in advance, building a fastener database, building a fastener selection knowledge base, solidifying the matching rule of a fastener, building a model of a device for selecting the fastener through a three-dimensional modeling tool, generating a fastener installation point on the model, selecting a connecting part corresponding to the mounting point, then calculating the interlayer thickness of the connecting part, finally calling fastener data, and quickly and accurately selecting a fastener combination for fixing the mounting point according to a fastener matching rule in a fastener selection knowledge base. The method and the system get rid of the traditional mode that manual searching and fastener mark selecting depend on experience in fastener assembly in the prior art, automatic and intelligent fastener combination selecting based on the fastener database and the knowledge base is achieved, the fastener assembly design efficiency is greatly improved, the fastener assembly design threshold is lowered, and the design error is reduced.

Description

technical field

[0001] The present invention relates to the equipment manufacturing industry, and more specifically, to a fastener selection method and system. Background technique

[0002] Fastener assembly is an important part of the research and development of equipment manufacturing enterprises. Due to the large number of fasteners involved in the design process of fastener assembly, and the limitations of current design methods and technologies, the development of fasteners has been seriously hindered. The improvement of assembly design efficiency and the improvement of assembly design level lead to a long product design cycle. The traditional fastener design method has the following problems: First, the fastener data management is not structured, and the fastener manual needs to be manually searched; second, there is no common fastener knowledge reasoning for the selection of fasteners, and it is necessary to select one by one ; The third is that there is no knowledge...
