车削带锥度的工件时,用一般方法调整小刀架都比较麻烦,需要多次试刀,才能将小刀架扳正确。下面介绍一种方法,调整一次即将小刀架调整好。如图所示,在小刀架转盘两侧各固定一粒钢球(钢球露出一半即可,并且距离越大越好)。当小刀架处于零角度时,两粒钢球距离S面的尺寸一样,即A=B,如果小刀架转一定角度,那么两钢球距s面的尺寸就不一样,尺寸差△s=|A-B|=L sin a,式中a Turning taper workpieces, using the general method to adjust a small turret are more troublesome, you need to test the knife several times in order to pull the knife holder pull the right. Here’s a way to adjust a small turret adjustment soon. As shown in the figure, a small ball on each side of the turret turntable (ball half exposed, and the greater the better). When the knife holder at zero angle, the two balls from the S side of the same size, that A = B, if the knife holder to turn a certain angle, then the two balls from s surface size is not the same, the size difference △ s = | AB | = L sin a, where a
