多功能钻头锥套,是在车床上使用的一种较理想的锥套,它即能单独退出钻头,又能同时分别退出钻头和锥套,而且还能防止钻头和锥套在特殊情况下随着被钻孔的零件一起转动。多功能钻头锥套,是在原锥套的基础上进行改进的,方法如下(见示图):1.将原锥套2后端中心钻一个圆通孔(孔的大小可根据锥套而定)配制个顶销5,然后 Multi-function drill taper sleeve is a kind of ideal taper sleeve used in lathe, it can exit the drill bit separately and exit the drill bit and the taper sleeve respectively at the same time, but also prevent the drill bit and taper sleeve from under special circumstances The parts to be drilled turn together. The multi-function drill taper sleeve is improved on the basis of the original taper sleeve as follows (see illustration): 1. Drill a round through hole at the center of the back taper sleeve 2 (the size of the hole can be determined according to the taper sleeve) Prepared a top pin 5, then
