摘要

研究了在烟草机械清洗设备中使用的一种摆动支点可变的平底从动件凸轮连杆组合机构。该机构将摆动从动件的枢轴安装在轨迹方向可调的滑块上，从动件进行复杂的平面运动，其输出角度的运动范围可根据输出要求进行调整。为了综合该机构，首先，建立了相关模型；然后，采用反转法和包络理论，推导了凸轮轮廓坐标求解模型；最后，选择相应的从动件运动规律，计算相应的凸轮轮廓坐标，通过插值得到整个凸轮轮廓曲线。利用该过程设计了实例机构的运动凸轮，并通过运动仿真进行了验证。研究工作解决了实际装备的设计问题，也丰富了凸轮-连杆机构的设计理论。

Abstract

A flat-bottom follower cam-linkage mechanism with a swing follower with variable pivot has been studied which is used in cleaning equipment of tobacco machinery. In this mechanism，the pivot of the swing follower is installed on a slider with an adjustable track direction，the follower performs a complex planar motion，and the motion range of the output angle can be adjusted according to the output requirements. In order to synthesize this mechanism，firstly，the relevant model is established. Secondly，the inverse method and the envelope theory are employed to derive the solving model of the cam contour coordinates. Finally，the corresponding follower motion law is selected，the corresponding cam contour coordinates are calculated，and the entire cam contour curve is obtained using interpolation. The motion cam of an example mechanism is designed by using this processes and verified through motion simulations. The study work solves the equipment needs and enriches the design theory of cam-linkage mechanisms.
