在机器制造业中,有些大型另件的要求几何形状,由于設备的限制,难以测得正确。我們在实际工作中,将小量具配上不同的工具,解決了几种大型另件測量上的困难問題,現分別介紹如下。一、利用杠杆百分表配上一只特殊卡鉗,(如图1所示)这样可以当作內孔比較規用。 In the machine building industry, the required geometry of some large parts is difficult to measure correctly due to equipment limitations. In practical work, we will allocate a small quantity of tools to different tools and solve the difficult problems of measuring several types of large ones. Now we introduce them as follows respectively. First, the use of a lever dial indicator coupled with a special caliper, (Figure 1) This can be used as a more regular use of the hole.
