一、杠杆式壁厚差检具: 我们厂设计制造的杠杆式壁厚差检具,如图1。测量时,使测头3接触销子内孔,调节螺母12,将杠杆4调至水平,弹簧6使测头始终接触销子内孔。活塞销旋转一周后,便可测得壁厚差值,将工件在 V形台 17上纵向移动,可测量活塞销任意横断面上的壁厚差。 要保证杠杆式检具的测量精度,关键在于测头至转轴10的中心距离与百分表测头至转轴中心的距离严格要相等,这样直接从表上读出读数,制造时应精确调整。其次轴承
First, the lever-type poor wall thickness Gage: Our factory design and manufacture of lever-type wall thickness Gage, shown in Figure 1. During the measurement, touch the probe 3 to the inner hole of the pin, adjust the nut 12, adjust the lever 4 to a horizontal level, and the spring 6 always makes the probe touch the inner hole of the pin. After one revolution of the piston pin, the difference in wall thickness can be measured and the workpiece is moved longitudinally on the V-table 17 to measure the difference in wall thickness at any cross section of the piston pin. To ensure the accuracy of the lever-type gages, the key point is that the distance from the center of the probe to the spindle 10 and the center of the spindle to the spindle must be exactly equal, so that the readings should be read directly from the watch and accurately adjusted during manufacturing. Second, bearings
