车床拉孔工具最近林海丰同志改进一种拉孔工具,把它装在C618K机床上可以使车床当作拉床,经过使用证明性能很好。以往用铰刀铰孔,加工一个工件需要10分钟,改用拉孔后,只需1分钟,拉刀寿命也比铰刀长。拉孔工具的结构如图1所示。拉具支承在车床尾座上,联接头1的一端同机床主轴联接,另一端同螺母2联接。联接头1同螺母2之间采用浮动牙
Lathe pull-hole tool Recently, Lin Haifeng comrades to improve a hole-pulling tool, put it on the C618K machine can make the lathe as a broaching machine, after using that very good performance. In the past reamer reaming, machining a workpiece takes 10 minutes, after the switch to the hole, just 1 minute, broach life is longer than the reamer. The structure of pull hole tool as shown in Figure 1. The puller is supported on the tailstock of the lathe. One end of the coupling head 1 is connected with the spindle of the machine tool and the other end is connected with the nut 2. Fitting 1 and nut 2 with floating teeth
