本文介绍两种在镗床上加工圆锥孔的工具,适用于重型机器制造,经使用证明,效果良好,精度较高。图1为加工短圆锥孔的专用工具。在镗床床头6上固装着空心圆柱形刀杆3,刃杆前端制成锥度并铣出凹形槽,槽内放有刀座滑轨1。滑轨的一端用铰链固定在刀杆3上,另一端可在槽内摆动。螺杆8用来调整刀座滑轨倾斜的角度。刀座滑轨上装有刀架2,与杠杆4连接。镗杆7上插有锥柄5。当镗杆进刀时,便推动杠杆4向前移
This article describes two kinds of boring machine taper hole machining tools for heavy machinery manufacturing, the use of proven good results, high accuracy. Figure 1 for processing short taper hole special tools. A hollow cylindrical arbor 3 is fixedly mounted on a boring machine head 6, a front end of the cutting bar is made into a taper and a concave groove is milled, and a knife seat slide rail 1 is arranged in the groove. One end of the slide rail is hinged on the cutter bar 3 and the other end is swingable in the groove. Screw 8 is used to adjust the tilting angle of the seat rail. Knife seat rail mounted turret 2, and the lever 4 connected. Taper shank 5 is inserted on the boring bar 7. When the boring bar is advanced, the lever 4 is pushed forward
