【摘要】：砂带磨削技术是制造业中一项重要的加工技术。随着砂带磨削技术的不断发展,无论在加工效率还是磨削质量上都有了很大的提高,砂带磨削的应用范围也涉及到各行各业。工业4.0概念的提出,拉开了机械制造与自动化技术相结合的序幕,砂带磨削与自动化生产相结合也成了未来发展的必然趋势。由于多年来学者们的研究重心一直向加工技术倾斜,导致砂带磨削的监测技术较为薄弱,而监测技术又是砂带磨削实现自动化生产必不可少的一项内容。本文以砂带磨削实验为基础,探索了一种以砂带表面图像来监测砂带磨削性能的新方法。搭建了砂带磨削平台和砂带磨削过程监测系统,并进行了相关实验。分析了砂带磨削过程中磨削力和砂带表面图像的变化规律,用MATLAB对砂带表面图像进行处理,以及识别不同磨削阶段的砂带表面图像特征,结合磨削力的变化规律,实现用砂带表面图像监测砂带磨削性能的目的。本文的主要内容包括以下几个方面:1、根据实验要求搭建砂带磨削平台和砂带磨削过程监测系统,其中砂带磨削平台为砂带磨削实验提供稳定的加工条件,砂带磨削过程监测系统用来记录和监测砂带磨削过程中的磨削力和砂带表面图像。2、在自主搭建的砂带磨削平台上进行磨削实验,记录不同种类砂带在磨削过程中的磨削力与砂带表面图像数据。3、分析砂带磨削过程中磨削力和砂带表面图像的变化规律,用MATLAB对砂带表面图像进行处理,编写程序识别不同磨削阶段的砂带表面图像的构成,结合磨削力的变化规律,最终实现用砂带表面图像的变化规律来监测砂带的磨削性能。
[Abstract]:Belt grinding technology is an important processing technology in manufacturing industry. With the continuous development of abrasive belt grinding technology, both machining efficiency and grinding quality have been greatly improved. The application of belt grinding also involves various industries. The concept of industry 4.0 has opened the prelude of the combination of mechanical manufacturing and automation technology, and the combination of abrasive belt grinding and automatic production has become an inevitable trend of future development. Because the center of gravity of scholars has been inclined to machining technology for many years, the monitoring technology of abrasive belt grinding is relatively weak, and monitoring technology is an indispensable part of belt grinding to realize automatic production. Based on the abrasive belt grinding experiment, a new method to monitor the abrasive belt grinding performance based on the surface image of the belt is explored in this paper. The abrasive belt grinding platform and belt grinding process monitoring system are built, and relevant experiments are carried out. The changing law of grinding force and surface image of abrasive belt during abrasive belt grinding is analyzed. The surface image of sand belt is processed by MATLAB, and the characteristics of surface image of sand belt in different grinding stages are identified, combined with the changing law of grinding force. The purpose of monitoring the abrasive belt grinding performance by using the surface image of the sand belt is realized. The main contents of this paper include the following aspects: 1. According to the requirements of the experiment, the abrasive belt grinding platform and the abrasive belt grinding process monitoring system are built, in which the abrasive belt grinding platform provides a stable processing condition for the abrasive belt grinding experiment. The abrasive belt grinding process monitoring system is used to record and monitor the grinding force and the surface image of the belt in the grinding process. The grinding experiments are carried out on the self-built abrasive belt grinding platform. The grinding force of different kinds of belt and the image data of belt surface are recorded. 3. The changing law of grinding force and surface image of abrasive belt during abrasive belt grinding is analyzed, and the surface image of sand belt is processed by MATLAB. A program is written to identify the composition of the abrasive belt surface images in different grinding stages. Combined with the changing law of grinding force, the grinding performance of the sand belt can be monitored by the changing law of the sand belt surface image.
