我车间钳工组长姜文起同志,最近改进了一种快速攻丝工具,提高了螺帽攻丝的生产效率,每2分钟可攻3个。攻丝工具如图1和图2所示。图中1是钻床床头。2是钻床上下移动轴。3是丝锥套,一端带锥度,插入钻床轴内,另一端有个方形孔,和丝锥的方筍配合。4是丝锥,方筍部分配在丝锥套内,不要太紧。5是工件,放在夹板6内,不要夹紧,只要使工件不转动就行了。7是固定座,装在钻床工作台上。
Comrade Jiang Wenqi, the fitter leader of my workshop, recently improved a quick tapping tool to increase the productivity of nut tapping, which can be tapped 3 times every 2 minutes. Tapping tools shown in Figure 1 and Figure 2. Figure 1 is a drill bed. 2 is up and down drilling axis drilling. 3 is a taper sleeve, one end with a taper, inserted into the drill shaft, the other end has a square hole, and tap the side of the bamboo shoot with. 4 is a tap, square shoots are allocated in the tap sets, not too tight. 5 is the workpiece, on the splint 6, do not clamp, as long as the workpiece does not rotate on the line. 7 is a fixed seat, mounted on the drilling table.
