摘　　要：在轨道板精调过程中必须用到精调框,而精调框又必须经常以标准框为基准进行校准,因此标准框结构尺寸的正确性及其标定对轨道板的精确定位十分重要。本文设计加工了CRTSⅡ型板标准框标定精密检测台,介绍了利用精密检测台进行标准框标定测量的原理及其数据处理模型,研制了标准框标定测量与管理程序,实现了标准框标定测量的自动化和程序化,确保了标准框标定工作的高精度和高效率。Fine-adjustment frames must be used in the fine adjustment for track slabs,and often be calibrated with the attached standard frame,so the correctness and the calibration of the standard frame play a very important role in the precise positioning for track slabs.In the paper,a precise calibration platform for standard frames of CRTSⅡ track slabs is designed and manufactured based on the calibration measurement principles and its data processing model is introduced.To ensure the high-precision and high-efficiency of the calibration of standard frames,the procedures for the calibration measurement and management have been developed with the autoimmunization and the programm of the calibration measurement is realized
