我们研制的数显孔距测量仪,解决了链条板等零件孔距的精密测量问题。一、原理与计算图1为数显孔距测量仪的工作原理图。将工件4置于测头3上,由于工件孔中心距A的变化,引起差动器2的膜盒内外室压力的变化而产生压力差△P。由于压力变化使差动膜盒1发生变形△S,带动膜盒上的顶杆上下移动,通过传感器5将
We developed digital display distance gauge, to solve the precise measurement of the distance between the parts such as chain board problems. First, the principle and calculation Figure 1 shows the working principle of digital display pitch meter. The workpiece 4 is placed on the probe 3, due to changes in the center hole A from the workpiece, causing the differential pressure chamber 2 inside and outside the chamber pressure changes resulting pressure difference △ P. As the pressure changes so that the deformation of the differential membrane box △ S, drive the plunger on the membrane box up and down, through the sensor 5 will be
