在农机修理制造中,经常要在 C630车床上加工长的轴类零件,如旋耕机的刀杆轴等。但 C630车床的拖板箱纵向移动是没有分度盘的(如图1所示),对于控制纵向加工尺寸很不方便。我们在去年对 C630车床进行了一项小改革,增添一套纵向移动分度盘装置,具体改装如下。将图1中Ⅰ轴和Ⅱ轴上的挡圈1、2取下,装上分度盘装置(图2)。固定在Ⅱ轴上的小齿轮7为 Z=40、m=1,分度盘齿轮3为 Z=98、m=1。套在Ⅰ轴上的偏心分度盘4,用两只内六角螺钉固定于拖板箱体上,其位置的确定要保证分度盘齿轮3与齿轮7正确啮合。分
In the agricultural machinery repair manufacturing, often in the C630 lathe machining long shaft parts, such as rotary tiller shaft and so on. However, the longitudinal movement of the pallet of the C630 lathe does not have an index plate (as shown in FIG. 1), which is inconvenient for controlling the vertical machining size. Last year we carried out a small reform on the C630 lathe, adding a longitudinal movement indexing device, the specific modification is as follows. Remove the retaining rings 1 and 2 on the I and II shafts in Fig. 1 and install the indexing device (Fig. 2). The pinion 7 fixed on the II axis is Z = 40, m = 1, the index gear 3 is Z = 98 and m = 1. Set in the I-axis eccentric index plate 4, with two hex screws fixed to the carriage body, the location of the determination to ensure that the index plate gear 3 and gear 7 properly engaged. Minute
