ILS－A精密因瓦水准标尺生产设备的研制

Development of ILS A Equipment for Machining Invariable Levelling Staff

高精度因瓦水准标尺是测绘、地震、地质等领域用于精密测量的必备设备，此前我国还没有专门用于生产精密因瓦水准标尺的设备。本文介绍了我们为某测绘器材厂研制的ＩＬＳ－Ａ水准标尺生产设备的基本原理和组成，特别介绍了冲孔模设计中的关键技术问题，以及采用光栅动态接长技术用于分划定位控制的优越性，最后给出了经双频激光干涉仪检测后的标尺分划精度，并对检测结果作了进一步讨论。

High precision invariable levelling staff is essential equipment in survey,seismology,geology field.Up to mow,there are still no special equipments for machining invariable levelling staff in our coantry.The paper presents the principle and configuration of ILS-A equipment we developed,especially,including the key to the technology for designing and makingdie and the advantages of using the dynamic grating connecting technology. Finally,we putforeward the results detected by using laser interferometer and a discussion.
