机械位移数字显示装置(简称数显)是一种能准确地自动显示机械位移量的检测装置。它具有较高的测量精度,并在提高劳动生产率、保证加工质量、降低成本、改革产品结构和减轻工人劳动强度等方面,都有明显的效益。数显装置可用于改造车床、镗床、磨床、铣床、电加工机床等,特别适用于大型、重型和精密机床的改造。数显技术推广应用于企业技术改造,使老设备精化,提高工艺装备的素质,用于发展新机床,也具有重要意义。一、数显装置的组成和工作原理 (一)组成数显装置通常由精密传感器(即榆测元件)和
Mechanical Displacement Digital display device (referred to as digital display) is a kind of accurate automatic display of mechanical displacement detection device. It has high measurement accuracy, and has obvious benefits in improving labor productivity, ensuring the quality of processing, reducing costs, reforming the product structure and alleviating the labor intensity of workers. Digital display device can be used to transform lathes, boring machines, grinding machines, milling machines, electrical processing machine tools, especially for large, heavy and precision machine tools transformation. Digital technology to promote the application of technological transformation of enterprises, to refine the old equipment, improve the quality of process equipment for the development of new machine tools, but also of great significance. First, the digital display device composition and working principle (A) consisting of digital display device usually consists of sophisticated sensors (ie Yu test components) and
