ロータリエンコーダと電子水準器を用いたサーボ傾斜角度計の開発

抄録

In this study, a clinometer which automatically measures the angular positioning deviations of a tilting axis is developed. Multi-axis machine tools consist of translational axes and rotary axes. The positioning accuracy of translational axes is checked by the laser interferometer. Although, there is no proper measuring instrument to measure the angular deviations of the tilting axis whose center line is lower than the top surface of table. Thus, a clinometer consisting of rotary encoder, pendulum with electronic level and servo motor was developed. The developed servo-clinometer mounted on the tilting rotary table moves around the tilting axis, and the pendulum moves by the servo motor so that the output of electronic level becomes 0 degrees. Through the experiment, it is confirmed that the developed method is enough to measure the angular deviations. The developed devise could be applied to the horizontal plane, however it was not able to measure inclined plane such as multi tasking lathes with a milling spindle.
