文档介绍：摘要
HQ3620是新昌鹤群机械有限公司新研发的多臂机,ZRB561是折入边装置,由于主要采用测绘仿造,性能有缺陷,因此需要对其进行优化。
本文分七章内容,探讨了国内外凸轮机构的研究状况,对HQ3620及ZRB561内的共轭凸轮机构进行机构分析,以测绘凸轮为基础,对其进行Pro/E运动仿真,再选择合适的运动规律拟合,由此拟合曲线我们可以通过计算公式计算凸轮轮廓,再将得到的凸轮进行运动仿真,将优化前后的曲线对比,计算拟合误差,从理论上判断优化的效果。样机的运行试验将最终确定凸轮的成功与否。
共轭凸轮作为多臂机的核心部件,其设计制造对纺织产品产量和质量有着至关重要的作用,但是由于其复杂的计算过程,增加了工程师的设计周期,一直是各大院校和制造厂家所要攻克的难点。为了方便快捷地完成共轭凸轮轮廓曲线设计,本文提出开发设计一款HQ共轭凸轮设计软件。该软件可在用户输入基本参数和运动参数后,自动生成共轭凸轮的轮廓线,减少了上述复杂的计算过程。因此研发该软件有着重要的实用价值。

Abstract
HQ3620 is a dobby and ZRB561 is a edge folding machine which are made by Xinchang HeQun machinery to being amde by surveying and mapping,there are many defects in the optimal desingn should be done for them.
This paper is divided into seven discusses the domestic and foreign research situation of cam mechanism and analys the conjugate cam mechanism of HQ3620 and the mapping cam as a foundation motion simulation is took in Pro/ should select an appropriate law of motion to fitting the curve. Then, we can calculate the profile of the cam by formula with those curve and take a motion simulation for the before and after,wo can calculate the deviation and judge the effect of optimization is good or test of the prototype will ultimately determine the ess or failure of the cam.
Conjugate cam as a ponent of dobby, its design and manufacture has a crucial role in the yield and quality of textile products. But because of plicated calculation process, it increase the cycle of design engineers, and it is always a difficult problem in the major universities and manufacturers to e. In order plete the design of conjugate cam profile curve quickly and easily, this paper puts forward the design of HQ conjugate cam design software can automatically generate the contour line of the conjugate after user input the basic parameters and movement parameters, reducing plicated calculation process. Therefore, research
