我厂在生产大型筒体类机械产品时,常遇到中空轴与筒体法兰盘配作时的孔加工问题(图1)。由于划线时误差在所难免,会导致两工件上法兰孔中心线不重合的情况。为此,我们制作了如图2所示的小塞子,以便解决问题。 I plant in the production of large cylinder type mechanical products, often encountered hollow shaft and cylinder flange plate matching hole processing problems (Figure 1). As the marking error is inevitable, will lead to two workpiece flange hole center line does not overlap. To this end, we made a small plug as shown in Figure 2, in order to solve the problem.
