在分划板镜筒上装一个辅助夹具(如图l所示),就可以将滑板装在上面,一面观察,一面调整。具体做法如图2所示。将辅助夹具6装在微米分划板镜筒4的外露部分,用螺丝5锁紧。略微松开顶丝2,装上纵向托板,用拨杆8的锥度端插入夹具6的调整孔7内,从目镜中观察,用手拨转夹具(即转动分划板4)。当标尺的某一条刻线分别对准两相邻0.1毫米双线的0微米和10微米两位置且偏差小于0.5
In the reticle tube mounted on an auxiliary fixture (shown in Figure l), you can install the skateboard above, while watching, while adjusting. The specific approach shown in Figure 2. The auxiliary fixture 6 is mounted on the exposed portion of the microdisplacement reticle 4 and is tightened with a screw 5. Slightly loosen the top wire 2, install the longitudinal pallet, and insert the taper end of the lever 8 into the adjusting hole 7 of the clamp 6. Observe from the eyepiece and turn the clamp by hand (ie turn the reticle 4). When the ruler of a ruler are aligned two adjacent 0.1 mm two-wire 0 microns and 10 microns two positions and the deviation is less than 0.5
