自动机床上的钻头磨损或折断之后,应能立刻检测出来,不然会使废品增多甚至造成事故。钻头的磨损或折断的检测多通过电机扭矩或发生的振动进行,但成本较高。这里介绍一种简单便宜的钻头折断检测装置。左图为一种使用超小型涡流传感器检测钻头前端折断与否的方法。加工完毕钻头返回主轴最上端时,具有导轨的传感器在气缸的驱动下前进到钻头位置, After the drill bit on the automatic machine is worn or broken, it should be detected immediately, otherwise it will increase the waste or even cause an accident. Drill wear or broken detection and more by the motor torque or vibration occurred, but the cost is higher. Here is a simple and cheap bit breakage detection device. The left is a method of detecting the front end of the drill bit broken or not using an ultra-small eddy current sensor. When the finished drill is returned to the top of the spindle, the sensor with the guide rail is advanced to the drill bit by the driving of the cylinder,
