UG机械加工专用夹具参数化设计平台开发+CAD图纸

摘要夹具作为机械制造业的一种重要工艺装备，它的设计与制造会直接影响到产品的研发周期和质量。缩短夹具设计周期，是计算机辅助夹具设计研究的重要领域，也是提高企业快速反应能力的一个重要环节。在当今市场竞争的激烈的背景下，企业信息化的需要迫在眉睫，企业对夹具的设计及制造提出了更高的要求。50296

针对上述现实问题，本文根据企业的需求开发了实用性强的基于UG平台的机床专用夹具设计系统，主要进行了下面几个方面的研究：

1、介绍了机床专用夹具设计的国内外研究现状，提出了基于UG平台二次开发的参数化设计方法，确定了系统的体系结构和功能模块。

2、阐述了机床专用夹具ug规范建模的方法，设计支持理论和设计使能技术，研究了机床专用夹具元件几何参数化建模及数据库建立的设计技术。

3、利用SQL Server、NX系统、Visual Studio 相互连接建立数据库，实现参数化功能，通过NX系统的二次开发，建立起人机交流的平台。

4、在NX系统参数化设计技术研究的基础上，建立了标准件的参数化和夹具常用夹具元件及非标准模型库、夹具体对比度分析机构、NX系统快速生成二维图的功能。

本文最后对开发NX系统平台的二次开发的机床专用夹具设计系统进行了详细的介绍，并给出了具体应用的实例，通过实例验证了所开发夹具系统的实用性。

Abstract Fixture as a mechanical process equipment manufacturing industry is an important，Its design and manufacture will directly affect the quality of the product development cycle and，Shorten the fixture design cycle, and is aided fixture design important area of research, but also improve rapid response cap abilities is an important part，

In today's fierce market competition in the context of enterprise information needs urgent，Business-to-fixture design and manufacturing requirements of a higher，Based on the needs of enterprises have developed practical tools based on UG platform dedicated fixture design system，Mainly for the following aspects of：

1、The development and research statement of machine fixture design are introduced，Based on the parameter design method of UG platform is put forward, The system architecture and functional modules are identified．

2、The information processing method of machine fixture design, The design

theory and design enabling technology is described，The geometric parametric

modeling design techniques is analyzed．

3、The use of SQL Server, NX system, Visual Studio interconnected to establish a database to achieve parametric function, through the secondary development NX system, and establish a platform for human-machine communication.

4、NX System parametric design technology, based on the establishment of a standard parametric and non-standard jig and fixture elements commonly used in model libraries, folders contrast analysis of specific institutions, NX system to quickly generate two-dimensional graph functions.

In the end，A fixture design system based on UG platform is introduced in detail，And the applied instance is put forward，From this instance，it Call be proved that the fixture design system has practical value．
