摘 要

機械產品的設計從產品構思、概念表達、結構設計、性能分析到最終的產品加工是一個非常復雜的過程，傳統的設計方法缺乏創(chuàng)新性、靈活性、效率低，已經嚴重影響了產品的上市時間，已成為現代化產品設計的瓶頸，而三維參數化計算機輔助設計是當今這一領域研究的熱點，是解決這一問題的唯一出路。本文結合車床主軸部件的傳統設計的工程實踐，利用計算機輔助設計的方法對主軸部件進行初步雜實踐，選擇并利用SolidWorks軟件對主軸部件進行三維參數化設計。同時，結合以上的計算機輔助設計的基礎上，再深入研究SolidWorks的參數化建模和特征建模的基礎上，綜合考慮SolidWorks與Microsoft visuul C++ 、Microsoft Access接口技術，參數化設計的數據結構與數據傳遞關系。基于SolidWorks，對SolidWorks進行了二次開發(fā)，實現了三維參數化計算機輔助設計系統的開發(fā)。最終，完成了數控車床主軸部件的三維設計，應征了系統的實用性。
最后，通過SolidWorks軟件的建模和系列零件設計表等的創(chuàng)建，實現了主軸零部件的參數化設計，并對裝配體的參數化設計進行了嘗試。

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.
