7.5 DIVIDING HEAD
A dividing head is one of the most important attachments of the milling machine and is almost indispensable. A typical construction of the dividing head is shown in Fig.7.20. The main spindle of the dividing head drives the workpiece by means of a 3-jaw universal chuck or a dog and live centre similar to a lathe.
The index plate of a dividing head consists of a number of holes with a crank and pin. The index crank drives the spindle and the live centre through a worm gear, which generally has 40 teeth as shown in Fig.7.21. As a result, a full rotation of the workpiece is produced by 40 full revolutions of the index crank. Further indexing is made possible by having the index plates with equi-spaced holes around various circles. This would allow for indexing the periphery of the workpiece to any convenient number of divisions.
The index plates available with the Brown and Sharpe milling machines are
Plate no.1: 15, 16, 17,18,19,20 holes

7.5分度头
A分度头是其中一个铣床的最重要的附件并且是几乎不可缺少的。 分度头的典型的建筑在Fig.7.20显示。 分度头的主要纺锤通过3下颌普遍牛颈肉或一个狗和活中心驾驶制件相似与车床。
The一个分度头的索引板材包括与曲柄和别针的一定数量的孔。 索引曲柄通过蜗轮驾驶纺锤和活中心，如Fig.7.21所显示，通常有40颗牙。 结果，制件的充分的自转由索引曲柄的40次充分的革命引起。 进一步索引由有使成为可能与等间隔的孔的索引板材在各种各样的圈子附近。 这将考虑到标注制件的周围对分裂的所有方便数字。
The索引板材可利用对布朗和Sharpe铣床是
Plate no.1 ： 15， 16， 17,18,19,20个孔
The在辛辛那提和帕金森分度头使用的索引板材是
Plate 1 ： 一面4,25,28,30,34,37,38,39,41,42个和43个孔
It也是可能从辛辛那提得到另外的板材增加索引能力a跟随：
Plate 2 ： 一面4,46,79,93,109,123,139,153,167,181,197个孔
Plate 3 ： 一面26,42,73,87,103,119,133,149,161,175,191个孔
