Surface treatment device for blade of wind driven generator

The invention discloses a wind driven generator blade surface treatment device, and relates to the technical field of blade surface treatment. The device specifically comprises a supporting seat assembly, a surface treatment assembly and a supporting and positioning assembly, the surface treatment assembly and the supporting and positioning assembly are both arranged at the top end of the supporting seat assembly, and wind driven generator blades are arranged at the top end of the supporting and positioning assembly and penetrate through the surface treatment assembly. Through the displacement deviation of the deviation rotating component and the positioning moving component, the axial deflection component is promoted to drive the grinding component to deflect, so that the axis of the vibration grinding machine is always kept perpendicular to the outer contour of the wind driven generator blade, a vulcanized fiber sand disc can conveniently grind the wind driven generator blade surface, and the grinding preci
