数控车床主轴部件的三维设计技术（本科毕业论文设计）.doc

摘 要

机械产品的设计从产品构思、概念表达、结构设计、性能分析到最终的产品加工是一个非常复杂的过程，传统的设计方法缺乏创新性、灵活性、效率低，已经严重影响了产品的上市时间，已成为现代化产品设计的瓶颈，而三维参数化计算机辅助设计是当今这一领域研究的热点，是解决这一问题的唯一出路。本文结合车床主轴部件的传统设计的工程实践，利用计算机辅助设计的方法对主轴部件进行初步杂实践，选择并利用SolidWorks软件对主轴部件进行三维参数化设计。同时，结合以上的计算机辅助设计的基础上，再深入研究SolidWorks的参数化建模和特征建模的基础上，综合考虑SolidWorks与Microsoft visuul C++ 、Microsoft Access接口技术，参数化设计的数据结构与数据传递关系。基于SolidWorks，对SolidWorks进行了二次开发，实现了三维参数化计算机辅助设计系统的开发。最终，完成了数控车床主轴部件的三维设计，应征了系统的实用性。
最后，通过SolidWorks软件的建模和系列零件设计表等的创建，实现了主轴零部件的参数化设计，并对装配体的参数化设计进行了尝试。

ABSTRACT

It is a very complicated process for the dseign of mechanical products from the products conception,expression of definitions,frame design,capability analysis to the final process of the products.The conwentional design technique has became a choke point of the modern product design is lacks innovation,agility and high efficiency,which has greatly influenced the time of the products coming into the market .However,3Dparametric computer aided design,the hotspot studying of this fielf nowsays,is the only way to solve this problem.This paper,combined with the engineering pratices of the traditional design of the Spindle Parts of CNC Lathe,put Spindle Parts of CNC Lathe into primary practice with the use of the technique of CAD.On the basis of the analysis of contrasting all sorts of 3D modeling software nowdays,we choose and make use of software SolidWorks to design Spindle Parts of CNC Lathe in 3D parametric.This paper does the framework analysis of the main loading parts of Spindle Parts of CNC Lathe with ANSYS,the finite element analysist software,which validates the reliability of this design. Meanwhile,combined with the practice of CAD, on the basis of luchbrating parametric modeling and characteristic modeling of SolidWorks ,and taken interface of SolidWorks and Microsoft Visual C++ Microsoft Access and the relationship between parametric designed date frame and date transformation synthetically into consideration,this paper puts forward a new developing method of 3D parametric designed software on the basis of SolidWorks.The second exploitation of SolidWorks has realized the exploitation of the 3D parametic CAD system.Finally,we completed the 3-D Design Technology of Spindle Parts of CNC Lathe.
Finally,though modeling and careating the series parts design table with SolidWorks,the paper completes parametric design of spindle parts,and parametric method of assembly is probed into initially.
