摘　　要：针对凸轮机构执行件最大行程不可调的缺点,提出一种新型微动凸轮及其CAD/CAM一体化设计制造方法。凸轮的结构为圆盘形,径向是沿着圆周方向均布的12个子曲面轮廓,同一径向位置处的轮廓曲线为拟合的余弦曲线,可以实现执行件最大行程可调的往复运动。应用VB6.0对SolidWorks进行二次开发,完成了凸轮曲面参数化设计,实现了设计模型、工序模型、装配体仿真模型及CAM制造模型的自动更新。依据模型进行了运动仿真验证和CAM加工仿真试验。通过分析,验证了该设计方法应用在凸轮的可行性及实用价值。Aiming at the disadvantage of the maximum can＇ t be adjusted for the cam mechanism, a new method of CAD/CAM integrated design and manufacturing for micro motion cam is put forward. The struc-ture of the cam is a circular disc, and the twelve same surface profiles are evenly distributed in the radial di-rection. The contour curve of the same radial length is the cosine curve fitting, which can realize the recip-rocating motion of the actuator in a certain range of travel. Using VB6. 0 as a tool to develop SolidWorks, finally realized the parametric control of cam surface. It make the design model, process model, assembly simulation model and CAM manufacturing model are updated automatically. According to the model, the motion simulation verification and CAM process simulation are carried out. The feasibility and practical val-ue of this design method in cam are proved through analysis.
