【摘要】：齿轮滚刀作为齿轮制造和加工中最普遍使用的刀具,其加工质量和精度与齿轮的工作效率、加工精度以及加工质量息息相关。齿轮不但在机械传动领域应用广泛,更是在整个机械行业中被普遍使用。在加工齿轮时,所使用滚刀的蜗杆类型大多数都是端面为阿基米德螺旋线的阿基米德蜗杆。尽管使用阿基米德螺旋线的齿轮滚刀不能切出理论的渐开线齿形,但是从实践加工结果来看,加工误差能够控制在允许的范围之内,而且制造工艺简单、方便,所以还是被广泛的使用。本文分析了国内外齿轮滚刀设计技术的特点,针对阿基米德齿轮滚刀数字化技术的研究与应用,采用参数化设计的思想,自动生成齿轮滚刀的二维生产用图,生产工艺过程和三维模型。通过对阿基米德齿轮滚刀的加工工艺进行分析和研究,进一步对滚刀蜗杆的加工过程进行仿真操作,最后对滚刀铲磨齿形进行计算以及铲磨砂轮的直径范围进行预测,进而为完成CAD/CAPP/CAM的一体化的方向而打下基础,使滚刀的设计和加工向数字化的方向不断迈进。论文主要采用AutoCAD 2007内嵌的VisualLisp编辑器进行二维零件图的AutoLisp程序的编制、利用基于Visual Studio 2010编程环境的C#编程实现二维滚刀窗体界面、三维滚刀网页界面的设计以及驱动接口程序的开发;使用Creo 2.0完成三维滚刀的参数化建模;运用Vericut 7.3对滚刀基本蜗杆的外形轮廓进行数控仿真加工;结合BP神经网络和Matlab 7.0对滚刀铲磨齿形过程进行计算并对铲磨砂轮直径进行预测。经过反复的程序测试,本设计系统是可行的、稳定的,具有一定的使用和推广价值。
[Abstract]:Gear hob is the most widely used tool in gear manufacturing and machining. Its machining quality and accuracy and gear working efficiency. Gear is not only widely used in the field of mechanical transmission, but also widely used in the whole mechanical industry. Most of the worm types used are Archimedes Worm with an Archimedes helix, although the gear hob using the Archimedes helix cannot cut the theoretical involute profile. But from the practical processing results, the processing error can be controlled within the allowable range, and the manufacturing process is simple and convenient. Therefore, it is still widely used. This paper analyzes the characteristics of gear hob design technology at home and abroad, aiming at the research and application of Archimedes gear hob digitization technology, adopts the idea of parametric design. Automatic generation of two-dimensional production of gear hobs, production process and three-dimensional model. Through the Archimedes gear hob processing technology analysis and research. Furthermore, the machining process of hob worm is simulated. Finally, the tooth profile of hob shovel grinding and the diameter range of shovel grinding wheel are calculated. Thus, it lays the foundation for the integration of CAD/CAPP/CAM. So that the design and processing of hobs to the direction of digitization. The paper mainly uses AutoCAD. The VisualLisp editor embedded in 2007 is used to compile the AutoLisp program of 2D part drawing. C # programming based on Visual Studio 2010 is used to realize the design of 2D hob form interface, 3D hob web page interface and the development of driver interface program. The parametric modeling of 3D hob is completed by using Creo 2.0. Vericut 7.3 is used to simulate the contour of the basic worm of hob. Combined with BP neural network and Matlab 7.0, the tooth shape process of hob shovel grinding is calculated and the diameter of shovel grinding wheel is predicted. After repeated program test, the design system is feasible and stable. Has certain use and promotion value.
