在成批生产中,采用定位切削可以节省测量工件的时间。在自动走刀时,当挡块将要碰着定位器时,就要改用手动走刀,否则就有可能发生事故。我们改用机床照明灯熄灭来定位的办法,进一步简化了操怍。线路如图所示,把一个行程开关(微动开关也可)串入照明电路中,图中1 K 是照明灯原有的搬把开关,2 K 是行程开关。装在定 In batch production, the use of positioning cutting can save the time to measure the workpiece. In the automatic pass, when the stopper will hit the locator, it is necessary to switch to manual, otherwise there may be an accident. We use the machine lights off to locate the way to further simplify the operation. Line as shown in the figure, put a trip switch (micro switch can be) string into the lighting circuit, the figure 1 K is the original light to move the switch, 2 K is the travel switch.
