床鞍导轨的平行性误差检验,通过图1的夹具进行测定,其平行程度的偏差可以很显著而正确地表达出来,在应用过程中效果很好。图1表示直接安置在床鞍上进行测量的检验夹具。角铁架1的一端成弧球形,另外一端开有一长溝槽,用螺钉8固定支板9,借助支板用螺钉2紧定轴10,按床鞍导轨罕行面距离的大小,调节轴10与止钉4之间的距离。这时使槓杆6的上臂端面触及千分表3,用手旋转表盖环,使盘(刻度盘)旋转对准零点之后进行测量。测量时,用手慢慢地推动夹具,则导轨不平
The saddle guide parallel error test, measured by the fixture in Figure 1, the deviation of parallelism can be very significant and correctly expressed in the application process works well. Figure 1 shows the test fixture placed directly on the saddle for measurement. One end of the angle iron frame 1 is arc-shaped, the other end is provided with a long groove, the support plate 9 is fixed by the screw 8, the shaft 10 is fixed by the support plate 2 by the screw 2, the size of the saddle guide- 10 and the distance between the nail 4. At this time, the upper arm end face of the lever 6 touches the dial indicator 3, and the watch ring is rotated by hand so that the dial (dial) rotates to the zero point for measurement. Measurement, the hand slowly push the fixture, the rail uneven
