该通用夹头能方便地装卸M5～M16规格的丝锥,牢固夹紧其柄部和方头,使用可靠。夹头体6的锥柄与车床尾座套筒锥度相配,滑动体3能在夹头体内滑动以满足丝锥切制螺纹时的纵向移动,滑动体内有拉伸弹簧8,用于攻丝完毕工件反转丝锥退出时,帮助滑动体复位。滑动体端部装夹丝锥部位是两个可调的结构。其一是丝锥柄部的夹持:它通过内螺母2拧紧时,由小弹簧11联接的三瓣夹块12沿滑动体内锥面移动,而灵活地夹紧丝锥柄部,直径从φ4.7(M5)到φ12.5(M16)均可。其二是丝锥柄端方头的夹紧:在紧接滑动体内锥面后的直径方向上,通过两只内六角螺塞5带动两淬硬夹紧圆柱4,夹紧大小不同的方头。φ10孔的作用
The universal chuck can be easily tapped M5 ~ M16 tap, firmly grip the handle and square head, the use of reliable. The taper shank of the chuck body 6 is matched with the taper of the tailstock sleeve of the lathe, the sliding body 3 can slide in the chuck body to meet the longitudinal movement of the thread cutting thread, the tension body 8 is provided in the sliding body for tapping the finished workpiece Reverse slide to help slide body reset. Slider body clamping taps are two adjustable parts. One is the clamping of the tap handle: when it is tightened by the inner nut 2, the three-piece clamping block 12 coupled by the small spring 11 moves along the conical surface of the sliding body to flexibly tighten the tap handle with a diameter from φ4.7 (M5) to φ12.5 (M16). The other is the taper handle side square head clamping: In the diameter direction of the cone immediately after the sliding body, driven by two hexagonal screw plug 5 two hardened clamping cylinder 4, clamping the square of different sizes. φ10 hole role
