【摘要】 随着科技的进步,经济的发展,汽车已经成为人们普遍的代步工具,随之而来就是废旧轮胎带来的“黑色污染”问题。轮胎翻新是目前极为常用也是行之有效的处理旧轮胎的方法,是一个解决废旧轮胎污染问题和节约资源的绿色环保产业,也是轮胎工业中不可或缺的重要一环。如何使翻新轮胎能够达到与新胎基本相等的里程数和安全性,是轮胎翻新的关键所在。基于此,本文的任务是研究和设计新型全自动轮胎打磨机。主要研究内容如下：首先,本文从轮胎翻新行业的意义,发展历史和废旧轮胎翻新原理着手,指出轮胎翻新可以带来巨大的社会效益和经济效益。通过分析比较国内外轮胎翻新的技术差距,指出本文研究的另一个意义在于提高国内轮胎翻新水平。目前国内的轮胎打磨系统多是半自动或者仍是人工打磨,精度差、效率低,新型的打磨机采用高精度交流伺服传动构成2轴数控进给系统,人机界面与PLC结合做控制器,实现了参数的在线柔性化快速调整,全自动打磨轮胎,打磨精度和生产效率成倍提高。其次,本文对伺服运动系统进行研究,建立了机床伺服运动系统的数学模型,分析系统的特性和影响系统动静态特性的主要因素,在此基础上对伺服系统中的曲线插补进行重点研究。在前人研究的基础上,应用了一种新型的插补算法,给出了插补算法的推导和最终插补算法。根据插补原理,进行了基于PLC的直线插补与圆弧插补运动程序的开发,并对其进行分析,使运动控制系统具有了平面点位运动控制和轨迹运动控制功能。文章对系统的软硬件都进行了设计,硬件设计包括系统各部分选型、端子的I/O分配、接线图等；软件设计包括控制主程序以及位控程序设计。通过编写一个GOT监控系统,设计了加工参数设定、报警显示、机床状态监控和点动操作画面,可实现各种监控和设定功能,方便操作和维修。最后,经实际运行证明,所开发的两轴数控轮胎打磨系统达到设计要求,能够适应轮胎翻新工艺,显著提高生产效率和产品加工质量。如果进一步完善,可以在该行业推广应用,创造可观的经济和社会效益。更多还原

【Abstract】 Thanks to the development of economy and improvement of technology, vehicles have become the most popular traffic tool for human, which also bring about the "black pollution" problem-the increased scrap tyres. Tyre retreading, nowadays the most efficient and commonly used way dealing with used tyres, is an environmental-friendly industry, orienting in solving tyre-pollution and saving resources. It is also a necessity to the whole tyre industry. So here is vital problem- how to make sure the retreaded tyres are as well as new tyres in security and mileage. So, to solve the problems, the full-automatic tyre grinding machine is developed. Following are the main ideas of every chapters.Firstly, this dissertation begins with the value and development of the retreading tyre industry, as well as the theory of retreading tyre. It shows tremendous social benefit and economic benefit of industry. And then, the dissertation analyzes the technology gap between domestic and foreign refurbishing tires industry, claiming another aims of the article-improving the domestic tyre retreading technological level. At present, the domestic retreading tyre system is almost semi-automatic or totally artificial, so the precision and efficiency is low. However, the new grinding system adapts the machine tool servo feeding, forming a two axis CNC and makes a controller combined with man-machine system and PLC. The new controller and two axis CNC together realize the flexible parameter adjustment, automatic grinding, and then efficiency and precision can be improved twice.Then, the paper researches the servo motion system and builds the machine tool servo feeding systematic mathematic model, which drives delivery function, analyzing the characteristic property of feeding system and the major factor of the static characteristic of system. On the basis of the studied curve of the servo system and previous studies, it proposes a new interpolation algorithm and interpolation algorithm eventually. Based on the principle of interpolation, developing linear interpolation and arc interpolation programs according to point to point compare interpolation theory, in this way making the system have point to point and track control functions.The paper also designs the hardware and software of the system. The hardware includes parts selection, terminal I/O distribution and wiring diagram. The software program includes control software design and procedures. The author programmed a GOT monitor system, designing a machining parameter setting, an alarm display, a machining state monitor and a jog operation screen. Under this program, the system can achieve monitoring and setting functions by switching between different screens, which is convenient for repairing and maintenance.Finally, through the actual motion, the invented two axis CNC grinding machine system works well and meets the normal operation.After further improvement, it can be promoted widely to develop the retreading tyre industry.更多还原
