这里介绍一种在拖拉机制造厂里广泛使用的一种用于检查两孔中心距的测量器。 将开口弹性销固定在测量器的一端,而将另一只开口弹性销装在测量器另一端的滑块里,弹性销的外径与孔的最大内径相配,这样当销子插入孔里时会自动定中心。安装在测量器上的滑杆式百分表用以测量滑块与测量器上的定位点间的距离。 使用时,先在校对规里将测量器调整到所需的尺寸,把两只开口弹
Here is a widely used in the tractor manufacturing plant used to check the distance between two holes measuring instrument. An open resilient pin is secured to one end of the gauge while the other open resilient pin is mounted in a slider at the other end of the gauge and the outer diameter of the resilient pin matches the maximum inner diameter of the hole so that when the pin is inserted into the hole Will automatically set the center. The slider-mounted dial indicator mounted on the measuring instrument measures the distance between the slider and the anchor on the measuring instrument. Use, first in the calibration rules will measure to the required size, the two openings play
