摘要
为了解决倾角仪校准的需求,研制出基于编码器的倾角仪校准装置。对倾角仪的零值误差、示值误差、测量重复性进行校准。采用系统精度为2″的编码器作为参考标准,保证了校准的精度。使用高精度的水准仪,将底座与夹具同时调整到0°水平度的位置。设计粗调微调结构,实现操作的灵活性。设计伺服电机驱动系统,实现自动化的调节。应用偏心轮设计了一套夹具结构,对不同倾角仪进行装夹。实验对分辨力为0.01°的数显倾角仪进行校准,能够达到校准要求。总之,该装置具有操作简单、校准精度高、适应范围广等优点。
To address the needs of the inclinometer calibration, calibration device developed inclinometers based encoder. Zero error inclinometer, showing error, measurement repeatability calibration. Using a system accuracy of 2' encoder as a reference standard to ensure the accuracy of the calibration. Using high-precision water level, the base jig while adjusting to the position of the horizontal degrees.Coarse Fine structure designed to achieve operational flexibility. Servo motor drive system design, automated adjustment. Applications eccentric design a fixture structure for different angle instrument setup. Resolution is the number of experiments was 0.01° of inclination instrument calibration, calibration requirements can be achieved. In short, the device has a simple operation,high precision calibration, adapt to a wide range of advantages.
