内径量表经频繁使用后,其可换测头的圆弧面会被磨平造成示值误差。通常的修理方法有整体结构式和镶嵌钢球式。这两种方法都存在一些不足之处。本文介绍内径量表测头的另一种修理方法——测头更换法。如图所示,用厚0.5mm 的紫铜皮包住可换测头的外螺纹部分,再固定在车床夹头上。将圆弧(或钢球)一端截去约10mm(整体结构式截削部位若在淬
After the inner diameter gauge is used frequently, the arc surface of the replaceable probe will be polished to cause the indication error. The usual method of repair is the overall structure and inlaid steel ball. Both of these methods have some shortcomings. This article describes another method of repairing an ID gauge probe - the probe replacement method. As shown in the figure, wrap the outer thread part of the changeable probe with a 0.5mm thick copper foil and fix it on the lathe chuck. The arc (or ball) at one end of the cut-off about 10mm (the overall structure of cut parts if quenching
