摘要

以实现工位台自动翻转与复位功能为目标,提出了一种由圆柱凸轮驱动的多工位回转式自动翻转与复位机构。每个工位均由曲柄滑块机构组成,通过凸轮曲线的变化控制滑块的位移变化,从而驱动曲柄旋转,完成工位台的翻转与复位动作。建立了自动翻转与复位机构的数学模型,通过改变机构的设计参数可以满足不同的工程实际要求。以预制硬质卷烟条盒的自动清空为例,研究了满足清空要求的多工位回转式自动翻转与复位机构的参数设计。以凸轮升程最小、翻转角度最大和竖直方向高度最小为多目标函数,以曲柄、连杆、凸轮升程等相关参数为自变量,进行了自动翻转与复位机构的优化计算,优化效果明显,并通过仿真分析验证了机构参数设计的合理性。

Abstract

In order to realize the function of the working station automatic turning and resetting,the multi station rotary automatic turning and resetting mechanism which is powered by cylindrical cam is proposed. Each working station is composed of a crank slider mechanism,the displacement of the slider is controlled by the change of the cam curve which drives the rotation of the crank and completes the turning of the working station.The mathematical model of this mechanism is established,through the variation of the design parameters can meet the requirements of different engineering requirements. In order to research the structure of multi station automatic turning and resetting mechanism fitting the empty request,the case of automatically empty the prefabricated hard cigarette is used as an example. The optimization of the automatic turning and resetting mechanism which is multi- objective is carried out. The minimum cam lift and vertical height,the maximum flip angle are the objective. The independent variables of this optimization are the parameters,such as the length of the crank and the connecting rod,the cam lift and so on. The optimization effect is obvious,and the rationality of the design parameter is verified by the simulation analysis.
