一种利用电磁分度原理来测量机床传动链精度的新方法,经过我厂长期研究,已获成功,并在生产中使用。实践证明,这是一种灵活简便并具有较高精度的传动链测量方法。一、电磁分度的简单原理电磁分度技术所用的基准元件是磁性分度盘,简称磁盘,如图1所示。它由基体1,隔离层2,磁性层3组成。基体1用铝、铜或铁制成。隔离层2为铜质。磁性层3是一层厚为0.015～0.03mm 的磷镍钴合金镀层。磁盘在专用的录磁架上进行磁化。图2是录磁原理的简图。它由一台频率极准确的石英振荡器产生信号,一路信号经分频、功率放大后去驱动同步电机,
A new method of using the principle of electromagnetic indexing to measure the accuracy of a machine tool drive chain has been successfully used and produced in our factory after long-term research in our factory. Practice has proved that this is a flexible and simple and with high precision drive chain measurement methods. First, the simple principle of electromagnetic division Magnetic indexing technology used by the reference component is a magnetic indexing plate, referred to as the disk, shown in Figure 1. It consists of the substrate 1, the isolation layer 2, the magnetic layer 3 composition. The base 1 is made of aluminum, copper or iron. Isolation layer 2 is copper. The magnetic layer 3 is a Phosphor-nickel-cobalt alloy coating having a thickness of 0.015-0.03 mm. The magnetic disk is magnetized on a dedicated magnetic record holder. Figure 2 is a magnetic recording principle diagram. It is a very accurate frequency of quartz oscillator signal, all the way through the signal frequency, power amplifier to drive the synchronous motor,
