在拖拉机、农业机械维修工作中,常常需要单件加工花键孔或孔的键槽,对没有插床的单位,可以自制一个分度夹具在牛头刨床上刨削键槽。夹具的结构及工作原理,如图所示。角铁座2用三根成品字形分布的螺栓1,固紧在牛头刨床工作台的T形槽上,钢制法兰盘9的外套与角铁座孔动转配合。法兰盘9在角铁座2的孔中的轴向间隙靠锁紧螺母4调整,锁紧螺母4与角铁座2之间加一个铜垫圈5。法兰盘9的端面圆周上均布24(或36)个分度孔。当定位销7在其中一孔定位后,再把紧定螺钉6
In the tractors, agricultural machinery repair work, often need to single-processing spline hole or hole keyway, for units without slotting, you can make a self-indexing fixture planing keyway on a shaper. Fixture structure and working principle, as shown. Angle iron seat 2 with three finished glyph distribution bolts 1, fixed in the shaper table T-slot, the flange of the steel flange 9 and the angle iron seat hole with the dynamic fit. Flange 9 in the hole of the angle iron seat 2 axial clearance by adjusting the nut 4, lock nut 4 and the angle between the seat 2 plus a copper washer 5. Flange 9 on the circumference of the uniform cloth 24 (or 36) indexing holes. When the positioning pin 7 is located in one of the holes, then set the screw 6
