从盲孔中取轴套是常常遇到的,我们可以用简单的方法来进行。如附图(a)所示,加工一个外径略小于轴套内径的圆柱塞,正圆柱塞上钻孔,并攻丝,然后如图所示焊在轴套上。这时,再用螺旋千斤顶或别的工具就可轻易取出轴套。第二种方法如附图(b)所示,加工一圆柱塞与轴套焊接,再在盲孔后加工一小孔,通以压力油,使轴套被压出。 Bushing from the blind hole is often encountered, we can use a simple method to carry out. As shown in Fig. (A), a cylindrical plug with an outer diameter slightly smaller than the inner diameter of the sleeve is machined. The positive cylinder is drilled and tapped, and then welded to the sleeve as shown. At this time, then use the screw jack or other tools can easily remove the sleeve. The second method shown in Figure (b), machining a cylindrical plunger welded with the sleeve, and then processing a small hole in the blind hole, through the pressure oil, so that the sleeve is pressed out.
