摘　　要：换刀机构中的复合凸轮完成刀具的插拔、转位动作,旋转动作通过弧面凸轮实现,直进运动由平面沟槽凸轮和正弦型从动件来实现。因为平面沟槽凸轮是加工在弧面凸轮的端面上,所以这种凸轮则成为复合凸轮。想要深入研究凸轮副的动力学性能,需要使用CAE技术,而前提是复合凸轮的精确建模,本文拟采用改进正弦加速度规律,使用Solidworks软件对圆弧凸轮的三维轮廓进行准确建模。Tool insertion and transposition is completed by composite cam in ATC, rotation is completed by surface cam, straight movement is realized by flat grooved cam and sine follower. The flat grooved cam is processed on end surface of surface cam, so it＇ s called composite cam. Under premise of accurate modeling, we can use CAE technology to do the thorough research to the dynamic performance of cam. In this paper, we use Solidworks to model 3D contour of cam accurately,in according to modified sine acceleration law.
