摘要
给出折弯模具检测装置的测量方案,建立该检测装置的理论测量模型。利用三坐标测量机作为折弯模具尺寸的外部检测校准设备,在折弯模具理论测量模型的基础上建立标定的数学模型。模型求解分粗标定和基于补偿量识别的标定两步,并用牛顿迭代法对补偿标定进行求解。在MATLAB环境下编程进行数值仿真,采用误差补偿方法获得标定后的检测装置测量模型。采用三坐标测量机和折弯模具检测装置对多组模具进行测量,对比实验结果,验证了标定模型的可解性与折弯模具检测测量模型建立的正确性。
A mers urement apoproach of bending die detection device was designed, and the theoretical measurement model of it was built.With the three-coordinate measuring machine as external measurement device of the bending die sizes, the calibration mathematical model was established on the basis of the measurement model. The solution of the calibration mathematical model consists of coarse calibration and compensation value calibration, and the compensation value calibration was solved with Newton iteration method. A numerical simulation was performed based on the software of MATLAB, and the measurement model of the calibrated detection device based on the error compensation was obtained. Then, the coordinate measuring machine and the bending die detection device was used to measure the sizes of the dies, the solvability of the Calibration model and the validity of the established measurement model were verified by comparison of the experimental data.
