我厂对外加工了一批弹性卡头,如图1所示,材料为65Mn。在X52K立式铣床上铣开宽度为6mm,长度为65mm的6条槽时,由于工件壁厚最薄处只有2.5mm,并且该工件有6条槽,故右端开口,不能用顶尖顶,铣削时易夹住立铣刀,给加工带来困难。为此,我设计了如图2所示铣弹性卡头槽专用夹具。
I plant external processing a number of flexible chuck, shown in Figure 1, the material is 65Mn. In X52K vertical milling machine milling width 6mm, a length of 65mm 6 slots, the workpiece wall thickness of the thinnest at only 2.5mm, and the workpiece has 6 slots, so the right end of the opening, can not be the top of the top, milling Easy to hold the end mill, to the processing difficulties. To this end, I designed the clamp shown in Figure 2 flexible chuck slot dedicated fixture.
