设计简介
摘 要
论文主要介绍了一种新型的自动售货机用取物箱的设计过程。在设计过程中还综合各方面因素对设计做了多次改进,简述了自动售货机的原理、分类以及内部结构与电子元件和国内外发展概况。就实际使用中所出现的因防盗板运动方式的不同所引起的取物箱高度过高而导致的取物箱体积增大的问题,提出了解决方法。运用PLC对自动售货机的控制系统做了设计。新型的防盗板联动机构具有结构简单、运动平稳、受力情况好、成本低、加工容易等优点。新型取物箱的结构设计运用了机械设计、机械原理、材料力学、创新思维等多方面的知识,是对所学知识的一次综合考验。此次设计的取物箱大多数零件都是钣金件,因此,为了完成这一设计,我学会了运用Solid Edge三维绘图软件,此软件最大的优点就是具有强大的钣金件建模能力。此外,我还充分利用了AutoCAD软件强大的参数化特征将设计图形显而易懂的呈现在大家面前。关键词:自动售货机;取物箱;防盗板;钣金;Solid Edge;AutoCAD;PLC
Abstract
This paper mainly introduced a new type of vending machine in the design process of take content box. Also synthesized various aspects factor in the design process to design does improved many times, has summarized the limiting condition and the domestic development survey which the vending machines,classification , the internal structure and electronic components ,the domestic and foreign development situation. According to the practical use of guard against theft occurred because of the different ways of plate movement caused by the content box highly exorbitant and take the lead to take content box the increase in size, solutions are put forward. I did the application of PLC control system of the vending machine to do the design The new security board linkage mechanism possesses simple structure, smooth movement, force of good, Low cost, easy processing. Take the new content box structure design using a mechanical design, mechanical principle, material mechanics, innovative thinking and so on various knowledge, is the knowledge of a comprehensive test.The design of the take content box is most parts metal sheet, Therefore, in order to finish the design, I learned to use Solid Edge 3D drawing software. Besides that I fully design the graph using the AutoCAD software formidable parametrization characteristic to reveal easy to understand present in front of us.Key words:Vending machine ;Take content box ;Security board;Sheet metal parts ;Solid Edge ;AutoCAD;PLC
