Research and Development of Cam Profile Curve Design System based on NX

提出了一种凸轮轮廓曲线自动化设计方法——利用数值驱动凸轮运动轨迹,根据凸轮分度曲线的运动规律计算轮廓线上任意点的坐标数据,然后生成凸轮轮廓曲线的数据文件,以该方法为基础,在NX平台上开发出通用平面盘型凸轮的自动化设计系统。该系统根据凸轮轮廓曲线的数据文件生成所需的凸轮模型,极大地提高了凸轮设计的效率和精度。

A method for cam profile curve automatic design is proposed that data value is used to drive cam＇s trajectory,calculate the coordinates of any point contour line data according to cam curve of the motion law,and then the contour curve data file is generated.On that basis,flat plate-type cam automatic design system is developed based on NX.The required cam model is generated according to the data file based on the system;the efficiency and accuracy of design are greatly improved.
