在车削多头螺纹时,我们采用了一种分头拨盘。它适用于在两顶尖间车削2、3、4、6等头数的螺纹,用起来简单、方便。使用时,将拨盘装在车床主轴上。拨盘上有12条分度槽(如图示),弯头鸡心夹头插在槽中。当车完一条螺旋槽后,将弯头鸡心夹头相应插入另一槽中,就实现了分度。鸡心夹头应转过的槽数= When turning long threads, we used a splitter. It is suitable for turning between the two top 2,3,4,6 number of threads, simple and convenient to use. When used, the dial mounted on the lathe spindle. There are 12 indexing slots on the dial (as shown). When the car finished a spiral groove, the corresponding bend elbow chucks inserted into another slot, to achieve the indexing. The number of slots that should be rotated in the center of the chicken heart =
