该分度台为简单的盒式结构,分度台面为纯机械式驱动。结构如图示:驱动机构由带有能手动回转齿轮b的操纵轴a,沿机架c底座燕尾槽滑动的齿条d以及与齿条相啮合的齿轮e组成。分度台面通过驱动轴K与齿轮e相连。为了不使分度台面回转,可在齿轮e上安装滚轮g以限制齿条的移动位置。由于蜗杆h与齿条d啮合,因此,分度台面的长度行程可通过调整蜗杆h进行。另外,蜗杆h采用键与调整轴i相连,所以蜗杆只能沿调整轴移动而不能转动。当操纵横杆n时,
The indexing table is a simple box structure, indexing table is purely mechanical drive. The structure is as shown in the figure: The driving mechanism is composed of a steering shaft a with a manually rotatable gear b, a rack d sliding along the dovetail groove of the base c of the frame c, and a gear e engaging with the rack. The indexing table is connected to the gear e via the drive shaft K. In order not to revolutionize the indexing table, the wheel can be mounted on the gear e to limit the rack movement position. As the worm h engages with the rack d, the length of the indexing table can be adjusted by adjusting the worm h. In addition, the worm h is connected to the adjusting shaft i by a key, so the worm can only move along the adjusting shaft and can not rotate. When operating the crossbar n,
