新型重型卧式车床尾座钻孔装置设计

New design of drilling and boring device for tailstock on heavy- duty horizontal machine

新型重型卧式车床尾座钻孔装置,是在重型卧式车床尾座主轴上通过1∶4短锥定位,安装了一套由手轮通过蜗轮蜗杆移动实现加工工件中心孔及钻孔的装置,满足了用户用尾座加工工件中心孔的需求。该装置结构简单、操作方便,可靠,实用。提高了机床使用效率,降低了生产、制造成本。

This device is positioning by 1：4 lolley needle on tailstock of heavy - duty horizontal machine, installing a device moved by worm wheel and worm which is controlled by handwheel for machining center hole and drilling hole. It will meet some customer requirements for machining center hole using tailstock, so it has characteristic of simple structure, easy operation, reliable, functional and it can increase its effi- ciency and cut down cost.
