滚齿机工作台的心轴由只适用于夹持有孔的齿轮,当遇到带轴的齿轮时就不好办。有人采用如图1的办法,用一个自动卡盘装在工作台上,夹住工件的下端带轴的部分,上端再用顶尖顶住,然后用千分表找正。这样做法所用的夹持时间较多,而且不够精确。现在介绍一种办法,采用像车床一样的双顶尖夹持法,如图2。上下都装好顶尖,先检查下顶尖,把千分表座放在工作台外面,千
The hobbing machine table’s mandrel is only suitable for holding the hole of the gear, when encountered with the shaft gear is not easy to handle. Some people use the method shown in Figure 1, with an automatic chuck mounted on the workbench, the lower part of the workpiece with the shaft clamping part of the top and then use the top to withstand, and then use the dial gauge to find out. This method used to hold more time, but not precise enough. Now introduce a way, using the same double latching method as lathe, shown in Figure 2. Top and bottom are installed top, first check the top, the dial gauge on the table outside, thousands
