机械工人(冷加工)59年1期,介绍了刘曾安同志报导的“简化外圆磨床操作的经验”一文,以下简称该文。我想对该文提出如下不成熟的意见,供读者参考。一、对该文图1的意见图1中B及H的互锁,用的不当:因为电路的操作程序是先作用H,按动主开关后,B还没有起作用,这时主动系统开始工作,也就是砂轮开始旋转。但是,要使工件旋转,必须按动副开关,而电路这时已被H切断,无法使B作用,也就是工件得不到旋转。即使先按动副开关,工件仍然不会旋转。二、对该文图2的意见图2中仍然没有很好地互锁B及H。因为按动主开关,使砂轮旋转以
Mechanical Workers (Cold Working) 59, 1 issue, introduced by Comrade Liu Zengan reported “simplified cylindrical grinder operation experience” one article, hereinafter referred to as the article. I would like to make the following immature opinions on this article for readers’ reference. First, the views of Figure 1 in Figure 1, B and H interlocking, improper use: Because the circuit is the first operating procedure H, press the main switch, B has not played a role, then the active system to start Work, that is, grinding wheel began to rotate. However, for the workpiece to be rotated, the sub-switch must be pressed and the circuit is now cut off by H, so that B can not be applied, that is, the workpiece is not rotated. The workpiece does not rotate even if the sub-switch is pressed first. Second, the views of the text in Figure 2 Figure 2 is still not well interlocked B and H. Because the main switch is pressed, the wheel is rotated
