摘 要
目前的手工绘图工具大都只能绘制直线和圆，对于椭圆的绘制，至今还没有
一种理想的实用手工绘图工具，故在这里就专门设计了这种椭圆规机构。本文的设计是采用双滑块连杆机构的工作原理，根据此原理设计并制作了该机构。本机构具有制作简单,使用方便,画出来的椭圆精确的特点,有较广的应用领域和市场前景。设计好方案后，着重对椭圆规机构中的支撑板、滑块、连接杆等相关重要零件的设计过程做出了设计，并对相关部件进行了加工工艺规程的编写，最后完成了椭圆规的实物制作。
本次设计在题目是椭圆规的设计与制造，目前，国内椭圆规的设计与制造的研发也在向朝着运行简洁化、功能复合化、功能多样化的方向发展，廉价，简单，方便成了工作台发展的主题。

Abstract
At present, most of the hand drawing tools can only draw straight lines and circles, and there is not an ideal practical hand drawing tool to draw the ellipse. The design of this paper is based on the working principle of the double slider link mechanism, and the mechanism is designed and manufactured according to the principle. The mechanism has the advantages of simple production, convenient use, accurate and precise drawing, and has a wide range of application fields and market prospects. Design is good, this thesis focuses on the ellipsograph institutions supporting plate, a slide block, a connecting rod and other related important parts of the design process make the design, and the relevant parts of processing procedure of preparation, and finally completed the ellipsograph physical production.
The design on the topic is the design and manufacture of the ellipsograph, at present, the research and development of the design and manufacture of the ellipsograph also to toward operating simplicity, function composition, functional diversification of the direction, cheap, simple and convenient to workbench development theme.
