【摘要】：随着中国制造业的崛起以及“中国制造2025”战略口号的提出,未来十年将成为中国制造业发展的黄金十年,机床行业也将迎来一个难得的发展机遇。导轨磨床作为加工大型机床大尺寸零部件的关键工作母机,其技术水平的高低直接影响机床行业甚至整个装备制造业的水平与发展。本文以山东威海华东数控有限公司开发的MKW5230A/3*160大型精密数控龙门导轨磨床为研究对象,以工作台运动控制为主要研究内容,对工作台的运动控制方案和算法进行设计和研究,使工作台获得优异的运动性能。第一章绪论主要介绍导轨磨床的国内外研究现状和未来的发展趋势,以及本文的研究背景。第二章先对导轨磨床的机械结构和液压系统做了简要介绍,然后介绍用来控制工作台运动的华中数控公司开发的HSV-ADI2位控单元的原理和功能。本文针对工作台在指定的距离里自动做往复运动的运动需求,提出三种不同的控制方案,分别记作方案一、方案二、方案三。第三章基于方案一,使用SSTT数据采集软件对不同控制电压下工作台的运动数据进行采集和分析,借此研究工作台受液压驱动的运动规律,为后续研究奠定基础。第四章使用位控单元控制工作台运动,对其PID控制算法做了深入研究。第五章结合方案一和方案二的优点提出方案三,重点研究了工作台定距功能的实现方案和算法。文章最后对三种方案进行对比,对各自优缺点进行总结。本文将导轨磨床工作台的运动控制要解决的问题归结为三个方面,分别是一解决变速控制问题,二解决换向控制问题,三解决定距问题。分别从这三个方面入手进行软硬件设计,最终解决工作台的整个运动控制问题。
[Abstract]:With the rise of Chinese manufacturing industry and the strategic slogan "made in China 2025", the next decade will become the golden decade of the development of Chinese manufacturing industry. The machine tool industry will also welcome a rare opportunity for development. The guide rail grinder is a key working machine for processing large size parts of large machine tools. The level of technical level directly affects the level and development of machine tool industry and even the whole equipment manufacturing industry. This paper uses MKW5230A/3*160 large precision NC developed by Shandong Weihai Huadong CNC Co., Ltd. The gantry guide rail grinder is the research object. Taking the motion control of the workbench as the main research content, the motion control scheme and algorithm of the worktable are designed and studied. The first chapter mainly introduces the research status and the future development trend of the guide rail grinder at home and abroad. The second chapter briefly introduces the mechanical structure and hydraulic system of the guide rail grinder. Then it introduces the principle and function of HSV-ADI2 position control unit developed by Huazhong CNC Company which is used to control the movement of workbench. Three different control schemes are presented, which are recorded as scheme one, scheme two and scheme three. The third chapter is based on scheme one. Using SSTT data acquisition software to collect and analyze the motion data of the worktable under different control voltages, so as to study the motion law of the table driven by hydraulic pressure. In chapter 4th, the position control unit is used to control the motion of the worktable, and the PID control algorithm is deeply studied. Chapter 5th combines the advantages of scheme 1 and scheme 2. Focus on the implementation of the workbench fixed distance function and algorithm. Finally, the three schemes are compared. In this paper, the motion control of the guide grinding machine table is reduced to three aspects, one is to solve the problem of variable speed control, the other is to solve the problem of commutation control. The software and hardware are designed from these three aspects, and the whole motion control problem of the worktable is finally solved.
