光学法接长须用精密线纹尺作为接长基准,这对许多中小企业颇受限制。并且当座标长度超过一米时,光学法渐不适应。现介绍一种不需增加任何计量设备的接长方法——双滑尺接长法:接长工具由两块滑尺组成,两尺电气中心距(L)为精确的偶数值,其误差很小,用它作为电气块规,可完成相邻两定尺的接缝调整,不受座标长度限制,现以1.5米长数显尺为例说明其要点。一、双层微动滑尺架滑尺1对准定尺的接长点,通过调缝使另一定尺的接长点与滑尺2对准,
Optical method then need to use long precision wire length as the reference length, which is quite limited for many small and medium enterprises. And when the coordinate length of more than one meter, the optical method gradually adapt. Is introduced without any increase in the length of the measuring method of the device - double slide then the length of the law: the length of the tool consists of two sliders, two feet from the electrical center distance (L) for the even even value, the error is Small, use it as an electrical block rules, can be completed adjacent two fixed seam adjustment, not subject to the length of the coordinate length, now 1.5 meters long digital ruler as an example of its main points. First, the double micro-slide slide rail slide 1 to align the length of the long point by adjusting the length of the other fixed-length points with the slider 2 alignment,
