Description

Technical Field

[0001] The utility model relates to a rotary grinding tool for a motor stator. Background Art

[0002] In the field of motor manufacturing and maintenance, the quality of the welding points of the motor stator is crucial to the performance and life of the motor. Therefore, grinding and polishing the welding points is an important step in the production process. Traditional grinding processes usually require workers to manually remove burrs and uneven parts generated during the welding process to ensure smooth and uniform welding points.

[0003] However, existing manual grinding methods have some significant limitations. Since motor stators are usually made of metal and are large in size, they can be very heavy, making it difficult for workers to easily turn the stator when performing grinding work. Workers need to turn the part to be ground in front of them for easy operation, but this process often requires a lot of effort and may cause worker fatigue and reduced productivity.
