针对高精度微小车床对刀间隙检测技术缺乏的问题,本文设计了一种二维对刀间隙检测装置对微小车床对刀的间隙进行检测。本次研究构建了一种光学图像测量系统,通过正交方式进行布置,并基于图像处理技术构建并完成了微小车床对刀间隙检测系统,对光学系统的标定采用标准量块完成。利用车床微动平台施加微小位移对本系统进行验证,实验证明,可有效提高微小车床对刀间隙识别与检测的精度(±15μm)。
In view of the lack of the knife gap detection technology for high precision and small lathe, this paper designed a two-dimensional knife gap detection device to detect the gap of the small lathe. In this study, an optical image measuring system was constructed, which was arranged by orthogonal method. Based on the image processing technology, the system of detecting the gap of the small lathe was built and completed. The calibration of the optical system was completed by the standard measuring block. The system is verified by micro displacement of the lathe fretting platform. The experiment proves that the precision of the clearance recognition and detection of the lathe can be effectively improved (± 15μm).
