内径量表可换测头容易磨损,甚至造成很废。本文介绍的更换方法如图所示,用0.5mm厚的紫铜皮包住可换测头1的螺纹部分,卡在车床上,将镶有钢球3的一端切去一小部分,然后用千分表校正外圆使其径向跳动在0～0.005mm之间。车平端面,将外圆车成外螺纹M4,长4.5mm,再用φ3.8钻头钻孔,深1mm,取一个新的护桥龙眼2,将其帽和钢球拧紧在外螺纹上即可。
Internal diameter gauge can change the probe easy to wear, or even cause waste. This article describes the replacement method shown in the figure, with a 0.5mm thick copper skin can be changed for the first part of the probe head, stuck in the lathe, will set the end of the ball cut 3 cut a small part, and then use the thousandths Table correction of the outer circle so that its radial runout in the 0 ~ 0.005mm between. Car flat end, the outer car into an external thread M4, length 4.5mm, and then φ3.8 drill hole, deep 1mm, take a new bridge longan 2, the cap and the ball can be tightened on the external thread .
