结构: 如图1、2所示,一把1号平面割刀,两把2号30°劈刀,两把4号30°倒角刀,一把5号割刀安装在下导向块上。两把3号8°劈刀安装在上导向块上。上下导向块用锥销3、螺钉2紧固在刀柄5上。八把刀分别在各自导向槽内滑动,转动各自的偏心轮9,车刀就能向前移动,以完成切削。操作步骤: (1)先将内外圆车至所需尺寸,再用5号割刀将工件端面光一刀,然后将小拖板向前移动一段距离,该距离等于工件厚度与5号割刀宽度之和。 (2)摇动中拖板,使3号8°左劈刀刀尖对准工件外径边缘,3号8°右劈刀刀尖对准工件内径边缘。
Structure: As shown in Figure 1 and 2, a No. 1 plane cutter, two No. 2 30 ° split knife, two No. 4 30 ° chamfering knife, a No. 5 cutter mounted on the lower guide block. Two No. 3 8 ° chopper mounted on the guide block. Upper and lower guide block conical pin 3, the screw 2 is fastened to the handle 5. The eight knives slide in their respective guide grooves, turning their respective eccentric wheels 9, the turning tool can move forward to finish the cutting. Operation steps: (1) the first round of the car to the desired size, and then the No. 5 cutter knife edge of the workpiece, and then move the small carriage forward a distance that is equal to the thickness of the workpiece and the No. 5 knife width Sum. (2) Shake the middle carriage so that the No. 3 8 ° left rifle tip is aligned with the outer diameter edge of the workpiece and the No. 8 right riveter tip is aligned with the inner diameter edge of the workpiece.
