数控摇尺仪,是较先进的一种新型摇尺机构。因该机构本身没有机械接点,所以精度较高、操作方便准确,且价格低廉。我场制造的数控摇尺仪,是采用较简单的光电码盘发送脉冲讯号方式。即通过齿轮齿条机构,将车桩直线量变为码盘的圆周转动。码盘上打有许多小孔,通过光电转换,即车桩每移动1毫米转换装置 NC rock scale instrument, is a more advanced a new type of rocker body. Because of the agency itself does not have mechanical contact, so the higher accuracy, easy and accurate operation, and low prices. I made the NC rocker, is the use of simple optical encoder to send pulse signal. That is, through the rack and pinion mechanism, the linear amount of the pile changes to the circular motion of the code plate. There are a lot of small holes on the code plate, through the photoelectric conversion, that is, each moving 1mm conversion device
