At present, the working principle of the electromagnetic drill is: use the electromagnet at the bottom to fix the electromagnetic drill, and then convert the rotary motion of the handle into the up and down linear motion of the rotor through the worm gear structure, and the rotation of the drill bit is driven by the motor. The disadvantages exposed by the electromagnetic drill at present are as follows: 1. Since the feed of the drill is manually controlled, the feed speed of the drill will be uneven, and the roughness of the processed hole will be large; in addition, when processing large-diameter holes, the operation is very laborious. 2. When a thick drill is used, the operating force is too large or the hole is about to be pierced, the force on the drill end is too large, and the electromagnet will be lifted up, and the uniform position cannot be guaranteed when it is re-fixed, so a large force will be generated. error.
