錐管螺紋联接可以在不使用密封材料的情况下获得良好的密封性,故而在管道联接中得到广泛应用。根据标准的規定:螺紋的中徑在一个錐面上(見图1)。这个錐面的錐度是1:16(或錐角2φ=3°34′48″),在一般沒有靠尺附件的普通螺絲車床上就无法进行加工。为此,設計了下述装置,可在C620型或其他有方刀架的車床上加工6吋以下的錐管螺紋。整个装置做成一个整体,安装在車床的方刀架上。由于結构比較紧凑,体积小,方刀架仍可轉动,因而保 Conical pipe thread connection can be used without sealing material to obtain a good sealing, it is widely used in pipe joints. According to the standard: the thread diameter in a cone (see Figure 1). The tapered surface has a taper of 1:16 (or taper angle 2φ = 3 ° 34’48 "), which can not be machined on conventional screw lathes that do not usually have a foot attachment. For this purpose, C620 or other square turret lathe machining 6-inch taper pipe thread below. The whole device made a whole, installed in the lathe side of the knife holder. As the structure is compact, small size, square knife holder can still turn Move, thus Paul
