摘　　要：对啤酒生产线上压盖机上的凸轮机构进行理论分析,利用SolidWorks和VB提取凸轮轮廓线,并结合MATLAB对凸轮和滚子从动件进行动力学分析得到其速度、加速度、压力角等数据。分析得出现用的啤酒生产线上凸轮不合理的地方,为了改善其性能采用了三次样条曲线改善凸轮轮廓,经分析采用三次样条曲线拟合的凸轮轮廓减小了现用凸轮机构的柔性冲击,提高了压盖机的性能。This paper makes a theoretical analysis of cam mechanism on the capping machine of beer production line, and using SolidWorks and VB to extract the cam contour line,then obtain the speed,acceleration and pressure angle data of cam and roller follower by combining MATLAB with dynamic analysis.The analysis shows that the cam is unreasonable.In order to improve its performance,three spline curves are used to improve the cam profile.After analyzing the cam profile fitted with three spline curves,the flexible impact of the present cam mechanism is reduced and the performance of the capping machine is improved.
