摘要
标准件的大量使用提高了产品设计效率,是现代制造的一个重要的特点。建立标准件库是一个很有意义的研究课题,对于机械零部件的生产和加工都十分重要。日益发达的今天,人们对互联网的依赖也越深。不同的操作平台,不同的应用系统,甚至不同企业间的数据互通,都需要一个共同的数据格式定义,XML的出现正可以解决这一切的问题。XML承担了数据表示和交换的角色,以XML表现的数据,具有严谨的结构、良好的可扩充性、可定制性,并具有平台无关性,空间无关性,便于网络传输是XML主要的四大特点,决定了其卓越的性能表现。本文提出了基于XML的标准件库的建库平台的系统构架,在对标准件进行层次分类和标准件参数归纳基础上,设计了XML表示的标准件文档。系统采用了参数数据和零部件图形相结合的机制,并把参数数据以XML文档的形式描述,从而使此标准件库初步实现了标准件库系统的无关性。最后,网上对标准件库的标准件数据查询。

Abstract
The much using of standard part improved the efficiency of product design, it is an important characteristic of modern manufacture. It is a very meaningful subject for research to set up the ponent. Storehouse that the production and processing of the mechanical .second people depend on deeper and deeper with wed and are developed day and day. It is necessary mon datum from the different operating platforms, different application systems, the data even among different enterprise are interflowed that xml can solve these problem. XML has undertaken the data expression and the exchange role by the XML performance data which has the rigorous structure, the good extendibility, may have custom-made the nature, and has the platform independency, the spatial independency, is advantageous for work transmission is the XML main four major characteristics which has decided its remarkable performance. This text has proposed being based on ponent storehouse of XML to build the systematic framework in the storehouse platform which on the basis of carrying on the level to classify and sum up with the ponent parameter to the ponent that designing ponent file of XML. System data and parameters used bining parts graphics, and data to the parameters described in the form of XML files, so that the standards of the initial pieces of the system to achieve a standard of unrelated. Finally
, the achievement of standards through standard pieces of the data information.
