弱磁力夹具用在数控线切割机床上,可以代替以前用机械的方法装夹工件。其结构如图所示。‘磁靴’里放了一块磁性较强的永久磁铁,当旋转起子口使之处于水平方向时,磁路经过‘磁靴’两极自行闭合,对外不显示磁性。把起子口旋转90°,(即垂直方向),这时上板和‘磁靴,均对外显示较强磁性。上板和‘磁靴’被隔磁的铜焊层分为左右两部分(即磁的两极),如果把铁磁材料的工件往弱磁力夹具上一放(必须横跨铜层),磁路通过工件闭合,则工
Weak magnetic clamp used in CNC wire cutting machine, you can use the mechanical method instead of clamping the workpiece. Its structure as shown. ’Magnetic shoe’ put a piece of strong magnetic permanent magnet, when the screwdriver mouth to make it in the horizontal direction, the magnetic circuit through the ’magnetic shoe’ pole to close itself, does not show the external magnetic. The screwdriver mouth rotated 90 °, (ie, vertical direction), then the upper plate and the ’magnetic shoe, are strong external magnetic show. The upper plate and the ’magnetic shoe’ are separated from each other by two layers of magnetic brazing layers (magnetic poles). If the workpiece of the ferromagnetic material is placed on the weak magnetic clamp (must cross the copper layer), the magnetic circuit Through the workpiece is closed, the work
