摘　　要：介绍了一种新型的智能加载激光洛氏硬度标准装置,装置采用电动结合砝码的加载方式,实现了力值加载的智能化过程控制;采用外差激光干涉测量技术,实现了压痕深度的无接触、高精度测量。试验表明:该装置稳定、可靠、准确度高,技术指标达到了国际洛氏硬度新定义的要求,具有很高的实用价值。A new standard Rockwell Hardness device with intelligent force-loading and laser measuring technology was presented in this paper. It adopted servo-motor and dead weights to carry out intelligent force loading,and used the technology of laser heterodyne interferometer to realize no-contact and high-precision measurement of indentation depth. The test results prove that this standard device is stable and reliable. The technical specifications meet the requirements of the new definition of the international Rockwell Hardness draft criterion. It has high practical value.
