工具特点此工具适用于在普通车床上加工各种细长轴类的中心孔,与在本页内介绍的《不停车顶尖》配合使用,钻中心孔时不用中心架,节省辅助工时,减轻工人的体力劳动,提高生产效率。工作原理工具结构见图。将工件左端顶在床头的不停车顶尖上,然后用手摇动尾座手柄,使反顶尖3的内锥面与工件的右端接触。继续族紧尾座手柄,此时床头顶尖退回,工件开始旋转,并带动反顶尖3旋转。同时反顶尖在尾座的推力下,往尾座方向退缩,使体
Tool Features This tool is suitable for machining center holes of various slender shafts on general lathes. It is used in conjunction with the “Non-stop Center” described on this page. Centering holes are not required for center frames, saving on man-hours and workers Manual labor, improve production efficiency. The working principle of the tool structure shown in Figure. The left end of the workpiece in the top of the bed does not stop the top, and then manually shake the tailstock handle, so that the inner cone of anti-tip 3 and the right end of the workpiece. Continued family tail tight tail handle, then bed top retracted, the workpiece began to rotate, and led the anti-top 3 rotation. At the same time anti-top in the tailstock thrust, to the tailstock retreat, so that the body
