为了充分发挥设备的潜力,我厂修配组长林祥镛同志针对我们车床忙钻床闲的特意,研究出一种利用2A125型钻床进行镗孔的工具,把过去需要在车床上加工的活,移到钻床上加工。工具的构造为附图,1是镗杆,用中碳钢(CT5)制成,上端带有锥度与钻床相配,下端与钻床工作台8相配,使镗杆与钻床主轴同心。2是镗杆螺帽,内有弧形槽与楔块3接触,所用材料与镗杆相同。楔块3上端有强力弹簧4抵住,下端装置着镗刀7。楔块和镗杆是由销子5连接起来,在调节楔块时,销子5还起到支点
In order to give full play to the potential of equipment, our factory repair team leader Comrade Lin Xiangxong deliberately aimed at our lathe busy drilling bed leisure deliberately developed a 2A125 boring machine boring tools, the past need to live in the lathe machining, moved to the drilling Processing. The structure of the tool is shown in the drawing. 1 is a boring bar made of medium carbon steel (CT5) with a taper at the upper end matched with the drilling machine and a lower end matched with the drilling machine table 8 so that the boring bar is concentric with the spindle of the drilling machine. 2 is the boring bar nut, which has an arc groove and wedge contact 3, the same material used and boring bar. Wedge 3 has a strong spring 4 against the top, the bottom of the device with a boring knife 7. The wedge and the boring bar are connected by a pin 5, and when the wedge is adjusted, the pin 5 also serves as a fulcrum
