一种通用量规用来测量孔的倒角深度,被测孔的直径可从2.5到24mm,并可用它确定倒角孔端平面的鍯孔深度,这一点,使用一般的量规是无法实现的。这种量规结构简单,它由下列零件组成:刻有分度线的微调螺套1,千分尺杆体2,测量样板5,支座4和定位销3。使用此量规需要编制孔的倒角深度及与之对应的测量分度读数的尺寸表。如果倒角深度和孔径超出所 A universal gauge is used to measure the chamfer depth of a hole. The diameter of the hole to be measured can be from 2.5 to 24 mm and it can be used to determine the counterbore depth of the chamfered hole end plane. This is not possible with conventional gauges. This gauge has a simple structure and consists of the following components: a fine adjustment screwdriver engraved with an index line, a measuring rod 2, a measuring template 5, a support 4 and a locating pin 3. The use of this gauge requires the preparation of a hole chamfering depth and the corresponding scale readings of scale readings. If chamfering depth and aperture beyond the
