摘要
为了缩短驱动包装机构的弧面分度凸轮设计时间,提高其运动稳定性,提出了一种新的弧面分度凸轮设计方法,并且与其他设计方法进行对比和分析。设计包装机构运动循环简图,选择转盘最佳运动规律曲线。根据转盘上滚珠运动曲线方程建立其数学模型,利用Matlab软件计算得出滚珠运动曲线的三维坐标点。将三维坐标点以文本格式导入UG软件中,生成滚珠运动曲线。利用UG软件中的扫掠功能切除凸轮毛坯,从而设计出弧面分度凸轮三维模型。在UG软件中对凸轮实体进行装配和运动仿真,并且与其他设计方法进行对比和分析。结果显示,在同等条件下,本文设计弧面分度凸轮时间缩短了50%,角加速度最大值降低了10.69%。本文设计了弧面分度凸轮,提高了设计效率和运动稳定性,为包装机构进一步优化设计提供理论支持。
In order to shorten the design time of the curved indexing cam driving the packaging mechanism and improve its motion stability,a new design method for curved indexing cam was proposed,and compared and analyzed with other design methods.Design a schematic diagram of the motion cycle of the packaging mechanism and select the optimal motion law curve of the turntable.Establish a mathematical model based on the equation of the ball motion curve on the turntable,and use Matlab software to calculate the three-dimensional coordinate points of the ball motion curve.Import 3D coordinate points into UG software in text format to generate ball motion curves.Using the scanning function in UG software to cut off the cam blank,a three-dimensional model of the curved indexing cam is designed.Assemble and simulate the cam entity in UG software,and compare and analyze it with other design methods.The results showed that under the same conditions,the time for designing the curved indexing cam in this article was reduced by 50%,and the maximum angular acceleration was reduced by 10.69%.The arc-shaped indexing cam designed in this article improves design efficiency and motion stability,providing theoretical support for further optimizing the design of packaging mechanisms.
