提出一种检测电力机车电机换向器变形量的新方案 ,在防振平台上安装双频激光干涉仪、过零发讯传感器、截面位置限位开关和高精度导轨 ,并以微电机自动控制二维运行的滑板、滑块为拖动装置。在车间现场环境条件下实时、动态测量电机换向器动压成形“超速”前、后直径值 ,通过微机数据处理 ,比较变形量 ,进行质量评估 ,打印输出结果。该系统性能稳定、精度高。 A new scheme to detect the deformation of motor commutator in electric locomotive is proposed. A dual-frequency laser interferometer, zero-crossing transmit transducer, cross-sectional position limit switch and high-precision guide rail are installed on the anti-vibration platform. Two-dimensional running skateboard, the slider for the drag device. In the workshop environment, real-time and dynamic measurement of motor commutator dynamic pressure forming “speeding” before and after the diameter value, through computer data processing, comparison of deformation, quality assessment, print output. The system has stable performance and high precision.
