C2150·GD卧式六轴自动车床,在更换修理固定支架时,固定支架孔的精镗必须在本机床上进行。为此,我们运用分配轴电机传动链,巧妙地解决了镗孔进刀问题。具体做法见传动系统图。脱开进给摩擦离合器,并同时合上牙形离合器,把分配轴电机的风叶卸下,装一手轮,摇手轮使分配轴电机反转,通过蜗杆—蜗轮—牙形离合器—Ⅶ轴—蜗杆—蜗轮,使分配轴(Ⅷ轴)获得与工作时相反的转向。这样,就可以利用纵刀架凸轮实现进刀运动,进给量由手摇分配轴电机的快慢来决定。
C2150 · GD horizontal six-axis automatic lathe, when replacing the fixing bracket, the fine bore of the fixing bracket hole must be carried out on this machine. To this end, we use the distribution shaft motor drive chain, cleverly solved the problem of boring feed. See the specific practice of transmission system diagram. Disengage the feed friction clutch, and at the same time close the tooth clutch, remove the fan of the distribution shaft motor, install a handwheel, shake the hand wheel to make the distribution shaft motor reverse, through the worm - worm - tooth clutch - VII axis - Worm - worm gear, so that the distribution axis (Ⅷ axis) with the work of the opposite turn. In this way, you can use the vertical tool carrier cam to achieve feed motion, feed by the hand shaft motor speed distribution to decide.
