基于SolidWorks Motion的灌装机分瓶机构凸轮曲线设计

目的对新型分瓶机构进行运动分析,并采用新方法设计组合机构的凸轮曲线,以提高设计效率。方法通过对此分瓶机构的运动分析,对从动件的运动原理深入了解的基础上,应用三维软件SolidWorks建立了简化机构模型,根据凸轮设计的反转原理,利用软件中的Motion分析功能,为梅花瓣构件及从动齿轮附加满足工程需求的驱动,然后进行了运动仿真。结果通过Motion分析中的"跟踪路径"功能对凸轮滚子中心点进行路径跟踪,得到了其轨迹曲线即凸轮的轮廓曲线。结论根据生成的凸轮曲线建立三维实体模型,与原有机构进行装配并仿真分析,验证了凸轮曲线的正确性,也验证了利用Motion分析进行凸轮曲线设计的高效性。

Design of the Cam Curve for Filling Machine Sub-bottle Mechanism Based on SolidWorks Motion

The motion of new type of sub-bottle mechanism was analyzed and a new method that can improve design efficiency was adopted to design the cam curve of the combination mechanism. Through the motion analysis of the new sub-bottle mechanism, the movement principle of the plum petals followers was elucidated clearly. The three-dimensional software SolidWorks was applied to build the simplified mechanism model, and according to the reversal principle of the CAM design, the motion simulation was conducted using the Motion analysis function of the software to add drives that met the project needs for plum petals member and driven gear. Through the "tracking path" function of the Motion analysis, the path of the cam roller center point was obtained and the path curve was also the cam profile curve. Based on the generated cam curve, the 3D model of cam was built, and the simulation analysis was carried out after the cam was assembled with the original mechanism. The result verified the accuracy of the cam curve and the efficiency of cam curve design using Motion analysis was also proved.
