在铣床上加工铰刀、立铣刀、铅头等圆柱形带柄工件时,多半是在分度头与尾架之间用顶尖把工件装卡,并且在工件尾部装上桃子夹头与分度头连接,因此在装拆工件同较费时。利用如图1的星形分度杆,可以节省装拆时间。星形分度杆的尾部是莫氏锥度4号,与分度头的锥孔配合;分度杆的端部铣成 In the milling machine reamers, end mills, lead and other cylindrical handle with the workpiece, mostly in the indexing head and tailstock with the top of the workpiece card loading, and the workpiece at the end of peach chuck and indexing Head connection, so in the demolition of the workpiece with more time-consuming. Using the star indexing lever shown in Figure 1, you can save the assembly and disassembly time. The tail of the star indexing rod is Morse taper No. 4, which is matched with the taper hole of the indexing head. The end of the indexing rod is milled
