本刊1977年第二期刊登了济南机床一厂计量室“压表蒙工具”一文,介绍了将百分表平蒙压装到表圈上,并使表面形成凸弧的工具。根据我们的经验,平蒙改造与压装合二而一的方法,有待商榷。工具本身也有不足之处。表蒙压装应保证压装后的几何形状,又应有足够的松紧度。用平蒙直接压入表圈,虽然也能形成凸弧,但几何形状(如图1虚线所示)不够理想。
The second issue of 1977 published a machine tool plant in Jinan Measurement Room “pressure gauge Mongolia tool” a paper describes the pressure dial gauge mounted on the bezel, and make the surface convex arc tool. According to our experience, it is open to discussion whether the method of reconstructing and pressing the flat and the flat should be combined. The tool itself also has shortcomings. Table Mongolia pressure equipment should ensure that after pressing the geometry, but also should have enough tightness. With Ping Meng directly into the bezel, although it can form a convex arc, but the geometry (as shown in dashed line in Figure 1) is not ideal.
