Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof motor grinding, in particular to a grinding device for explosion-proof motors. Background Art

[0002] The three-phase asynchronous explosion-proof motor is a motor with special design and performance. It is mainly used in hazardous environments such as flammable and explosive gases and dust. The working principle of the three-phase asynchronous explosion-proof motor is basically the same as that of the ordinary three-phase asynchronous motor. It is powered by a three-phase AC power supply to generate a rotating magnetic field in the stator winding. The rotor generates an induced current under the action of the rotating magnetic field, thereby generating electromagnetic torque to make the motor rotate.

[0003] In a flammable and explosive environment, any rough surface or protrusion inside the motor casing may generate sparks due to friction and become a potential fire source. The inner surface of the casing is smoother after grinding, which is conducive to air circulation and heat dissipation. Therefore, in the production process of three-phase asynchronous explosion-proof motors, it is necessary to grind the inside of the casing of the three-phase asynchronous explosion-proof motor, and a grinding device is usually used for grinding the casing of the three-phase asynchronous explosion-proof motor.

[0004] The grinding device for the three-phase asynchronous explosion-proof motor casing usually fixes the casing on a rotating disk. The staff fixes the casing of the three-phase asynchronous explosion-proof motor by a clamp on the rotating disk, and then grinds the casing of the three-phase asynchronous explosion-proof motor by a grinding disk. During the above operation, since the staff needs to grind the casing of the three-phase asynchronous explosion-proof motor and remove the polished three-phase asynchronous explosion-proof motor casing, the grinding device will be stopped for a long time. Based on the above problem, the present application proposes a grinding device for explosion-proof motors. Utility Model Content
