在可进行各种钻孔和攻丝操作的普通车床上,如果采用一种自带夹头的丝锥与车床尾座钻夹配合使用,那么,当打完中心孔和完成钻削加工后,我们可直接将其装夹到尾座的钻夹上,而无需更换钻夹,从而节省了工时。该丝锥主要由丝锥、套杆和夹头三部分组成(见图)。套杆是一个由冷轧钢辊制成的长1—固定在丝锥尾部方形驱动部分63.5mm、内切圆直径为19mm的六角形杆。的定位螺钉 2—夹头 3—套杆它的一端与一丝锥柄部套接,并用一定位螺钉定位丝锥柄部的方形驱动部分。另一端则与一个长47.6mm、内切圆直径为
In general lathes that can perform a variety of drilling and tapping operations, if a chuck with a chuck is used in conjunction with a lathe tailstock drill chuck, then after drilling the center hole and completing the drilling, It can be directly attached to the tailstock drill chuck, without having to replace the drill chuck, thus saving man hours. The tap is mainly composed of taps, rod and chuck three parts (see photo). The rod is a long, cold-rolled steel roll 1-fixed to the taper of the square drive section 63.5mm, inscribed circle diameter 19mm hexagonal rod. 2-Chuck 3-rod One end of the sleeve with a taper shank sockets, and use a set screw positioning taper shank square drive section. The other end with a length of 47.6mm, inscribed circle diameter
