千分表表盘上刻度数字的顺序安排,直接关系到它能否指示正确的数值,因此值得好好研究。指针式千分表的测量范围,一般认为1mm,它的刻度是由两部分组成,一部分是小指针的刻度,即0.1mm刻度,另一部分是大指针的刻度,即0.001mm刻度。读数时,先按小指针读取0.1mm及其以上的数值,后按大指针读取0.1mm以下的数值(最小至0.001mm)。小指针和大指针指示的数值之和即为千分表上的读数值。如图1所示的读数值为0.123mm,因此千分表的刻度数字顺序,必须根据它的结构特点,在整个示值范围内,从零点开始以正向行程按递增的方式加以标注数字。倘若千分表除外尺寸测量外,还用于内尺寸测量(即用于内径千分表)。这时,应在原刻度的数字旁,按相反方向标注另一行数字,此数字的尺寸应
Dial indicator on the scale of the order of the figures directly related to whether it can indicate the correct value, it is worth a good study. Measuring range of the dial indicator, generally considered 1mm, its scale is composed of two parts, one part is a small pointer scale, that is 0.1mm scale, and the other part is a large pointer scale, that is, 0.001mm scale. Reading, press the small pointer to read the value of 0.1mm and above, press the big pointer to read the value of 0.1mm (the smallest to 0.001mm). The sum of the small pointer and the large pointer indicates the reading on the micrometer. The reading shown in Figure 1 is 0.123 mm. Therefore, the numerical sequence of the dial indicator must be numbered incrementally, starting from zero and starting at zero, based on its structural characteristics, over the entire indication range. In addition to the dial gauge size measurement, but also for internal dimensions (ie, for the internal diameter gauge). At this time, beside the number of the original scale, mark the other line in the opposite direction. The size of this figure should be
