大直径深螺母的加工,由于螺孔深,需要采用较长的刀杆,因此刀杆悬臂量大,切削时会产生较大振动,严重影响表面加工质量。 现介绍在普通车床上加工大直径深螺母的方法。 1.加工方法 加工示意图如右边所示: 车刀3装在刀杆6的刀孔中,用螺钉2固定。刀套4与工种5内孔配合间隙为0.3～0.5mm。车削时,刀套与工件相对滑动。车刀径向进给时,刀杆在刀套内前后滑动;车刀轴向进给时,刀杆通过螺钉8及槽口b带动刀套同时作轴向运动。刀套上开有缺口a,以便于进刀和排屑。图中,刀杆材料为45钢,调质200～220HB刀套材料为HT15～33。
Large-diameter deep-nut machining, due to the deep screw hole, the need to use a longer arbor, so a large amount of arbor cantilever, cutting will have a greater vibration, seriously affecting the quality of surface processing. Now introduced in the ordinary lathe processing large diameter deep nut method. 1. Machining method The sketch map on the right is shown as below: The turning tool 3 is installed in the tool hole of the arbor 6 and fixed with the screw 2. Knife sleeve 4 and 5 kinds of work with the hole clearance of 0.3 ~ 0.5mm. Turning, the relative sliding sleeve and the workpiece. Radial tool feed, the arbor in the knife sleeve before and after sliding; turning tool axial feed, the arbor through the screw 8 and notch b drive sleeve at the same time for axial movement. Knife open on a notch a, in order to feed and chip removal. In the picture, the material of the cutter bar is 45 steel, the material of the tempered 200 ~ 220HB cutter is HT15 ~ 33.
