计量光栅是一种新兴的位移测量元件,是现代化仪器、机床实现数控化、自动化及精密计量的关键元器件。计量光栅测量技术在国外已被相当普遍的应用,在国内也越来越受到重视,在计量技术中已开始占据重要地位。由成都工具研究所研制生产的KZC—1型光栅传感器和DGX—1、SGX—2单、双座标光栅数字显示仪配套组成的光栅测长系统,是一种精度高、稳定性好、测量范围大、效率高的数字化长度座标测量系统,具有安装、调整方便等优点,可方便地应用于多种新型精密仪器和机床,以及对旧设备的传统座标测量系统进行更新。现已成功地应用于万能工具显微镜改造、高精度螺旋线动态误差测量仪器、凸轮动态误差检查仪等。KZC—1型光栅传感器的结构为开启式,即光栅读数头与主尺分开,气隙由仪器或机床导轨
Metrology grating is a new type of displacement measuring element, which is a key component of modern instrument and machine tool for numerical control, automation and precision measurement. Metering grating measurement technology in foreign countries has been quite common applications, more and more attention in China, in measurement technology has begun to occupy an important position. The KZC-1 grating sensor developed and manufactured by Chengdu Tool Research Institute and the grating length measuring system composed of DGX-1 and SGX-2 single-and double-coordinate grating digital display instruments are high accuracy, good stability, Large-scale, high-efficiency digital length coordinate measuring system, with the advantages of easy installation and adjustment, can be easily applied to a variety of new precision instruments and machine tools, and the traditional coordinate measuring system of the old equipment is updated. Has been successfully applied to universal tool microscope transformation, high-precision spiral dynamic error measurement instruments, cam dynamic error tester. KZC-1-type grating sensor structure for the open type, that grating read head and the main ruler separated by air gap or machine tool guide
