本文介绍一种专为修复车床尾座用的镗孔装置,并能适用于小批量制造车床对尾座进行镗孔。这种修复尾座孔的方法,是在车床上进行镗削,重换套筒、丝杆、螺母等。经实践证明,操作方便,保证质量。大修后车床的主要部份,如主轴箱、床身、大小拖板、尾座座板等需按原要求的精度修复、校正后,才能进行尾座的镗孔。镗孔装置的结构见右图。套,被夹持在车床卡盘上,轴承、垫、螺母、镗杆组合在支承座内。按车床中心
This article describes a boring device designed to repair the tailstock of a lathe and is suitable for boring tailstocks for lathes in small lots. This method of repairing the tailstock hole is carried out in the lathe boring, replacement sleeve, screw, nut and so on. Proved by practice, easy to operate, to ensure quality. After the overhaul of the main part of the lathe, such as the spindle box, bed, the size of the drag plate, the tailstock seat plate according to the required accuracy of the original repair, after correction, tailstock boring. The structure of the boring device is shown on the right. The sleeve is clamped on the lathe chuck, the bearing, the pad, the nut and the boring bar are combined in the bearing seat.
