Problems solved by technology

Existing magnetic suction drill electromagnets tend to generate heat under long-term high-current operation. Long-term heating will cause the magnetic properties of the electromagnet to decline, resulting in potential safety hazards; at the same time, magnetic suction drills usually slide the drill body through guide rails, Debris is easy to stick to the guide rail, which affects the accuracy of the guide rail
When drilling, it is usually used with coolant, and if the coolant is continuously opened at a large flow rate, it will also cause a lot of waste of coolant

Abstract

The invention discloses an efficient magnetic attraction drill. The drill comprises a magnetic attraction seat, an electric drill, a guide rail and a motor arranged in the electric drill, the motor is connected with a fan, the electric drill is internally provided with an air duct matched with the fan, the air duct is connected with an air valve, and the air valve is provided with a first blowpipe connected with the magnetic attraction seat and a second blowpipe matched with the guide rail; and the air valve is provided with an adjusting part, the electric drill is provided with a sliding part for driving the adjusting part, one end of the sliding part drives the adjusting part, the other end of the sliding part is provided with an adjusting rod for adjusting cooling liquid, the electric drill is provided with a spraying device matched with the adjusting rod, and a temperature control piece matched with the sliding part is arranged in the magnetic attraction seat. According to a device for adjusting the flow of the cooling liquid according to the temperature of a strong magnetic coil in the magnetic attraction seat and the structure for conducting air cooling on the strong magnetic coil, the drilling efficiency of the magnetic attraction drill is greatly improved, and meanwhile waste and loss of the cooling liquid are reduced.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a high-efficiency magnetic suction drill. Background technique [0002] The magnetic suction drill is a power tool that is often used to drill holes on the side wall. It mainly relies on the adsorption force of the electromagnet to adsorb on the workpiece to punch the workpiece vertically. Existing magnetic suction drill electromagnets tend to generate heat under long-term high-current operation. Long-term heating will cause the magnetic properties of the electromagnet to decline, resulting in potential safety hazards; at the same time, magnetic suction drills usually slide the drill body through guide rails, Sometimes debris is easy to stick to the guide rail, which affects the accuracy of the guide rail. When drilling, it is usually used with coolant, and if the coolant is continuously opened at a large flow rate, it will also cause a lot of waste of coolant. Contents...
