钻机立轴导管磨耗大,是修配加工的主要备件之一。在技术革命运动中,铇工唐明同志提出了一种定位夹具,减少了划线和鉋制时校正时间,提高了铇制肖糟工效三倍多(原为4小时,现只为1.2小时)。该夹具构造如图所示。由V 形底座①,压盖②、压盖螺丝③和肖槽定位锁母④组成。由底座螺丝连接 The vertical shaft of the rig wears large and is one of the main spare parts for repair and processing. In the technological revolutionary movement, Comrade Tang Ming proposed a positioning fixture that reduced the time required for scribe and planing and improved the effi ciency of the sculpted slasher by more than three times (it used to be 4 hours and now only 1.2 hours). ).
