Description

Technical Field

[0001] The utility model belongs to the technical field of blade root automatic grinding devices, in particular to a blade root automatic grinding device. Background Art

[0002] In the manufacturing process of wind turbine blades, glass fiber reinforced epoxy resin is usually used as the main material and is vacuum injected into the mold for injection molding. During vacuum injection molding, the precise cutting of the blade root cannot be guaranteed. Therefore, the uneven blade root needs to be polished after the injection molding is cured. Currently, manual assisted polishing is commonly used, which has low work efficiency, high labor intensity, poor polishing effect, and cannot ensure that the blade root is polished flat and level, affecting the blade connection strength. When the existing polishing equipment needs to be polished in the height direction of the blade during operation, the equipment needs manual intervention, and the blade is irregular in shape during the polishing process. When placed on a horizontal plane, the polishing effect of the blade is not ideal.

[0003] For example, the utility model with announcement number CN208629142U discloses a wind turbine blade root grinding device. In the technical solution of this patent, a liftable support leg is fixedly connected to the bottom of the support frame, a spirit level is installed on the support frame, and the longitudinal moving device includes a driving motor and two rotating shafts respectively arranged at both ends of the support frame. The driving motor is fixedly connected to the outside of the support frame, and the main shaft of the driving motor is coaxially fixed to one of the rotating shafts. Gears are fixedly connected to both ends of the rotating shaft, and the two gears on the same side of the two rotating shafts are connected by a transmission belt. During use of this device, the blades are placed horizontally, but the shape of the blades is irregular, which will cause errors in the blades during grinding. Therefore, an automatic blade root grinding device is proposed. Utility Model Content
