Description

Technical Field

[0001] The utility model relates to the field of fan blade balance testing, in particular to a fan blade balance cutting machine. Background Art

[0002] Dynamic balancing deweighting refers to a method of removing a certain amount of weight in the unbalanced direction of a rotating workpiece to achieve balance. In the production process of fans, using dynamic balancing deweighting to correct the fan is a necessary production process, because if the mass imbalance of the fan blades during rotation causes them to vibrate at a specific frequency, thereby generating noise and greatly reducing the service life of the fan. The traditional dynamic balancing deweighting operation method is: (1) experienced workers find the location of the unbalanced direction of the fan blades, and then manually grind or cut them off; (2) install the fan blades on a machine tool and remove the weight through drilling and other methods. However, the above traditional deweighting operation methods require repeated corrections until the unbalanced amount of the fan blades meets the requirements to ensure the quality of the fan blades. Such deweighting operation methods have low correction accuracy and efficiency and cannot meet the needs of mass production of fans. Utility Model Content
