摘要机械常用零件的设计与制图是一项繁琐且重复性大的工作,人工设计费时费力容易出错,花在创造性设计的时间大大减少,导致产品开发周期长,产品质量差,市场竞争力弱。本文以法兰为例，旨在讨论、研究如何利用三维设计软件Solidworks实现在机械设计中快捷地设计、使用标准件，使设计人员把更多的时间投身到创造性的工作中去,以达到缩短产品开发周期的目的。50121

    SolidWorks是一套三维机械CAD软件，它的应用编程接口，提供了程序员直接访问SolidWorks的能力，可以很方便地对Solidworks进行二次开发，本文中利用VB作为开发工具，研究在SolidWorks环境下标准件库的开发。

法兰连接是管道施工的重要连接方式。在工业管道中，法兰连接的使用十分广泛。故对法兰盖的系列化设计，对于管道设计来说具有十分重要的意义。

    本课题开发过程有：

1. 根据国家法兰标准利用Access建立标准法兰的数据库文件;

2. 利用VB建立程序的界面;

3. 编写代码将VB和所建立的数据库进行连接，从数据库中调用法兰建模所用的参数

4. 编写代码将VB和SolidWorks连接运用前面的参数进行三维建模

Abstract

The design and drawing of common parts of the mechanical is a tedious and repetitive work, it is time-consuming to manual design and easily prone to error, and the time spent on creative design significantly reduced, resulting in long product development cycles, the products of poor quality, weak competition in the market. This paper give blind flange as a example, aims to discuss on how to use 3-D design software Solidworks in mechanical design to achieve quickly design, the use of standard parts, allowing designers to devote more time to participate in creative work, and to achieve shorten the product development cycle purposes.

Solidworks is a set of 3-D mechanical CAD software, its application programming interface, providing direct access to the Solidworks; it is easy for the second development to Solidworks. This paper use VB as a development tool,research how to develop the standard component library.

The flange connecting is an important connection in pipeline construction. In the industrial pipeline, the use of the flange connected is in a very wide range. Therefore, the series designs of the blind flange have a great significance of the pipeline construction. In this paper, has an example of its application.

The methods used in the process of developing of this subject are：

1. According to the national standard flange flange using the Access database file to establish standards

2. Establish procedures using VB interface

3. VB and write code to connect to the database created from a database call parameters used by modeling the flange

4. Write code to VB and SolidWorks connection parameters using the previous three-dimensional modeling

Keyword: Blind Flange; SolidWorks; Visual Basic；Marco
