在车制零件时,有时卡盘夹紧零件后,扳手忘记取下就开车,以致造成事故。现介绍一种只有扳手取下后,机床才能启动的安全装置。如图1所示在机床启动电路前串联一微动开关(常开),若要开车,必须接通微动开关。微动开关接通的方法是利用扳手的重量,按压开关的按钮。安全装置安装在机床主轴箱的箱体上。如C618 K的扳手常放在箱盖拉手上,在拉手下面固定安全装置。从这装置中引出两条导线串联在启动开关上,只要扳手放在该位置上,微动开关就成闭合状态。此时接通机床的启动开关,才能启动。反之
In the car parts, sometimes chuck clamping parts, wrenches forgot to remove the car, resulting in accidents. Now introduce a wrench removed, the machine can start the safety device. As shown in Figure 1 before the start-up circuit in the machine in series with a micro switch (normally open), to drive, you must turn on the micro switch. Micro switch is connected by using the weight of the wrench, pressing the switch button. The safety device is mounted on the housing of the machine headstock. Such as the C618 K wrench often placed on the handle of the box, the handle below the fixed safety device. Lead from the device in the two leads connected in series on the start switch, as long as the wrench on the position, the micro switch into a closed state. At this point turn on the machine’s start switch, to start. on the contrary
