国产各种磁力探伤机的充磁装置大部分都是手动或脚踏方式,对现场操作人员尤其是作成批的零件检查并不是很方便的。我们在充磁控制线路中加装微动行程开关,通过同步电机带动的凸轮盘控制连续充磁的间歇时间,达到连续自动充磁的目的。这种装置在上海产 DZ-2000型和营口产 JDC-1000型磁力探伤机上安装后,使用较方便,现介绍如下:充磁装置实物照片见图1,凸轮盘上有15个等间距的齿,它由背面的 DT-2型同步电机带动作顺时针旋转,速度为2转/分,充磁和间歇时间各为1秒钟。行程开关为 LX-11N/1型,其触头由一个带有φ10×
Domestic magnetron testing machine magnetizing devices are mostly manual or pedal mode, on-site operators, especially for the bulk parts inspection is not very convenient. We magnetize the control line with the addition of micro-trip switch, through the synchronous motor driven cam disk intermittent continuous control of the magnetizing time, to achieve the purpose of continuous automatic magnetizing. This device is installed in Shanghai production DZ-2000-type and Yingkou production JDC-1000-type magnetic detection machine installed, the use of more convenient, are described below: Physical magnetization device photos shown in Figure 1, the cam plate has 15 equally spaced teeth , It is driven by the back of the DT-2-type synchronous motor clockwise rotation speed of 2 rev / min, magnetizing and intermittent time of 1 second each. Stroke switch for the LX-11N / 1 type, the contact by a with φ10 ×
