一、结构特点1.结构合理、使用方便,是车床经常要用到的加工各种规格的内、外螺纹及小孔的通用夹具,也能在镗床、钻床上使用。2.加工范围广,调节紧固刀具螺钉9,既能夹持住M6～M30标准粗牙丝锥及方柄在20×20毫米以内的细牙丝锥攻制内螺纹,也能夹持住直柄钻头进行钻孔。3.采用螺母压紧钢球的快换装置,比较方便地把通用攻丝。钻孔夹头8从导向滑动套5前部内孔中卸掉,换上通用套扣快换夹头24,即能夹持住从
First, the structural characteristics 1. Reasonable structure, easy to use, is often used to lathe machining a variety of internal and external threads and holes of the common fixture, but also in the boring machine, drilling machine. 2. Wide range of processing, adjust and tighten the tool screw 9, can hold the M6 ~ M30 standard coarse tap and square handle within 20 × 20 mm fine tap tap tapping internal thread, but also hold the straight handle Drill for drilling. 3. The use of nut compression steel ball quick change device, more convenient to general purpose tapping. Drill chuck 8 from the front of the sliding sleeve 5 is removed from the inner hole, put on the universal set of quick change chuck 24, which can hold from
