摘要

随着拉丝模孔径越来越小型化,常用的拉丝模内孔参数测量方法已经不能满足测量的要求。本文将旋转测量法和激光衍射相结合,实现了微小孔孔型参数的高精度测量。测量过程中,通过控制步进电机不断旋转拉丝模中心轴而产生不同的衍射效果,在CCD上分别采样圆孔和椭圆孔衍射图像,利用衍射图像和孔型参数之间的函数关系实现拉丝模各参数的测量。最后通过测试得出各参数的测量误差约为1%,实验结果表明该系统可靠性好、精度高。
        As the aperture of wire drawing die is becoming smaller and smaller,the parameter measurement of the common wire drawing die inner hole can't meet the requirement. The high precision measurement of micro aperture pass was realized by combining the rotation measurement and laser diffraction. In the measurement process,center shaft of drawing die was continuously rotated by controlling of stepper motor,which produced different diffraction effects. The diffraction images with round or elliptical hole were sampled respectively on the CCD. The pass parameters of drawing die were measured through the function relationship between diffraction images and pass parameters.Finally,the measurement error of about 1 % was obtained. The results show that the system has good reliability and high precision.
