摘要
以圆柱分度凸轮机构为核心部件,设计出了一种新型凸轮式环形分度装置.为了得到运动性能良好的圆柱分度凸轮机构,首先对圆柱分度凸轮机构的设计系统进行了完善,并用该系统软件结合Creo 3.0建立了凸轮式环形分度装置的数字化样机,进而得到系列化的凸轮式环形分度装置.该装置的设计采用分度凸轮与从动盘不在同一箱体中的方法,并采用轻型回转支撑轴承解决了设计过程中从动盘的支撑和密封的难题,使整个装置的结构更加简单化.最后基于ADAMS软件对简化的数字化样机进行运动学仿真,通过对其角位移、角速度、角加速度以及碰撞线和力矩曲线的分析验证了装置设计的合理性与正确性,对该装置的设计和工程应用具有一定的参考价值.
In this paper,a new cam ring indexing device is designed with the cylindrical indexing cam mechanism as the core part.In order to obtain a cylindrical indexing cam mechanism with good motion performance,the design system of the cylindrical indexing cam mechanism is improved,and the digital prototype of the cam ring indexing device is established by using the system software and Creo3.0.The design method of the device adopts indexing cam and the driven disc are not in the same cabinet,and the use of light rotary support bearings to solve the problems of the drive plate support and sealing in design process,so that the whole device structure is more simple.Finally,based on the ADAMS software,the kinematic simulation of the simplified virtual prototype is carried out.The rationality and correctness of the device design are verified by analyzing the angular displacement,angular velocity,angular acceleration and the collision line and torque curve.The design and engineering application of the device has a certain reference value.
