摘　　要：本论文对专用轴承保持架数控分度工作台,进行了研究、讨论和设计。依据分度工作台的工作原理,齿轮传动、电机驱动、结合数控、涡轮蜗杆传动等相关知识,设计出一种运用于加工中心的轴承保持架数控分度工作台。为了提高工作台的分度精度,为了保证工作台的精度和承载能力,采用了涡轮蜗杆传动方式;且可以自身旋转一定角度来加工斜孔,以满足更多的加工需求。通过丝杠来调整工作台与主轴之间的位置,通过涡轮蜗杆的传动调整旋转角度和分度,通过此设计可缩短轴承保持架的制造周期,提高产品质量和精度。This paper studies,discusses and designs the NC indexing table of special bearing cage.According to the working principle of indexing table,gear drive,motor drive,combined with NC,worm drive and other related knowledge,a NC indexing table for bearing cage used in machining center is designed.In order to improve the indexing accuracy of the worktable and ensure the accuracy and bearing capacity of the worktable,the worm gear transmission mode is adopted;It can rotate itself at a certain angle to process inclined holes to meet more processing needs.The position between the worktable and the main shaft is adjusted by the lead screw,and the rotation angle and indexing are adjusted by the transmission of the worm and worm.Through this design,the manufacturing cycle of the bearing cage can be shortened and the product quality and accuracy can be improved.
