汽室套是蒸汽机车上的易磨耗件,在机车入厂检修时,均须更换。每台机车上有四个汽室套。汽室套的菱形汽口匀布在汽室套的圆周上(见图1),加工比较困难。我厂在1964年曾制造过一台专用铣床,用于铣削汽室套汽口。该铣床主要靠人按按钮,控制电磁离合器,使被加工的汽室套和刀具实现相对运动,完成汽口的铣削。由于工件和刀具靠电钮控制,操作频繁,要求工人注意力必
Steam chamber sets are easy to wear on the steam locomotive, locomotive into the factory overhaul, must be replaced. There are four steam chamber covers on each locomotive. Steam chamber sets of diamond-shaped steam mouth evenly in the vapor chamber sleeve circumference (see Figure 1), processing more difficult. I plant in 1964 had made a special milling machine, used for milling steam chamber sets mouth. The milling machine mainly by pressing the button to control the electromagnetic clutch, so that the steam chamber sleeve and the tool to be achieved relative movement, the completion of steam mouth milling. As the workpiece and the tool by button control, frequent operation, requiring workers to pay attention
