我们在修理一合进口机床时,发现有一个控制开关已损坏,无法修复,当时未找到相同的开关。我们就把国产的LW 6-4/E002型开关的控制接线圈(图1)改成图2,使开关的接线和控制程序满足了要求。改装方法:开关每对触点的“接通”与断开是由开关内部的凸轮控制的。改变凸轮的形状,就可以使开关触点的“接通”或是“断开,改变。例如,开关在+60的位置时,原21-22控制触点的凸轮形状及装配位置如图3,此时该触点是断开的。我们拆掉 When we repaired an imported machine tool, we found that a control switch was damaged and could not be repaired. At that time, the same switch was not found. We put the domestically produced LW 6-4 / E002 switch control coil (Figure 1) into Figure 2, the switch wiring and control procedures to meet the requirements. Retrofit method: Switch Each contact on the “on” and off by the switch internal cam control. For example, when the switch is at the position of +60, the cam shape and the assembly position of the original 21-22 control contact are as shown in Fig. 3 At this point the contact is open
