通常加工管接头上的锥管螺纹是先加工好锥体,再用板牙套丝扣,这样加工生产效率低,劳动强度大,质量也很难保证。为此,我们设计了一种转头刀杆,用来加工锥管螺纹,大大提高了效率和加工质量。转头刀杆的结构如图所示,主要由转头、刀杆座、内套、拉簧、滚轮和靠模板等组成。使用时,将靠模板8固定在床身上,刀杆座5装在刀架上,抽掉小刀架丝杆,在拉簧6的作用下使滚轮9紧靠在靠模板斜面上。用横
Pipe processing is usually the first cone on the pipe thread is processed cone, then die sets threading, so that the production of low efficiency, labor-intensive, quality is also difficult to guarantee. To this end, we have designed a turret bar that can be used to machine taper pipe threads, greatly improving efficiency and machining quality. Rotor head structure as shown, mainly by the rotor, arbor, inner sleeve, extension spring, roller and by the template and other components. When in use, the template 8 is fixed on the bed body, the pole seat 5 is mounted on the knife holder, the small knife holder screw is withdrawn, and the roller 9 abuts on the inclined plane of the template under the action of the extension spring 6. With horizontal
