基于UG NX表达式的空间凸轮精确建模
Precise Modeling of the Spatial Cam Based on UG NX Expression
摘要
Abstract
The cam profile curve of cam mechanism in high speed and precise automatic mechanism is very complex,it brings difficulties for creating 3D precise modeling. In addition,the cam profile curve with much lower accuracy can not meet the requirements in the subsequent CAE and CAM. The design principle of cam profile curve is to determine the equation between the displacement of the follower and the rotation angle of the cam according to the motion rule of the follower required in operation. The cam profile curve would be drew based on the equation,assuring the accuracy of the generated cam profile curve. The article takes cylindrical cam of rectilinear translating follower with quintic polynomial motion law as an example to introduce the method of the cylindrical cam parametric modeling based on UG NX.关键词
