在镗床和特殊机床用的重型镗杆上装一组镗刀时,若要更换刀具,使新镗刀能较快地调整到所需要的镗孔尺寸,是比较困难的。由于操作条件和工作环境的限制,在调整时,常需耗费大量的辅助时问。如果稍改进一下刀具的结构,就可避免这个缺点。如图1所示,在镗刀的端面上装1调整螺钉,并放置在镗杆的固定支承面上。加工时,可将镗刀从镗杆上取下来用图2所示的调整镗刀的工具,预先将镗刀调整到要求
When boring a boring tool on a boring bar and a heavy boring bar for a special machine tool, it is difficult to change the tool so that the new boring tool can be quickly adjusted to the required boring size. Due to operating conditions and work environment constraints, often need to spend a lot of auxiliary time adjustment. If you slightly improve the structure of the tool, you can avoid this shortcoming. As shown in Figure 1, install an adjustment screw on the end face of the boring tool and place it on the fixed bearing surface of the boring bar. Processing, the boring tool can be removed from the boring bar to use the tool shown in Figure 2 to adjust the boring tool, the boring tool beforehand adjusted to the requirements
