Embodiment 1
[0016] Embodiment 1, with reference to figure 1 , a fan blade tip repair method, comprising the following steps:
[0017] (1) Cut off the damaged blade tip of blade 1 as a whole, and treat the end surface of its truncated surface as a slope surface with a slope of 1:50-60 and a length of 300-400 mm, and roughen the surface of the slope surface ;
[0018] (2) Make the tip cover 5 according to the design of the original blade tip, and grind the end surface of the installation port of the tip cover 5 into a slope surface 4 that fits the end surface of the truncated surface of the blade, and the surface of the slope surface is also polished and roughened , whose slope and length are the same as the slope of the blade end face;
[0019] (3) The outer surface of the blade 1 and the tip cover 5 is polished and roughened within a range of 300-400mm extending from the outer joint along the blade axis direction, and the inner surface of the blade 1 and the tip cover 5 is polished from...

Abstract
The invention discloses a fan blade tip repairing method. The fan blade tip repairing method comprises the following steps that (1) a damaged blade tip is overall cut off, and the end face of the truncation surface of a blade is machined into a rough slope face; (2) a blade tip sleeve is designed and manufactured according to the original blade tip, and the end face of an installation opening of the blade tip sleeve is polished into a rough slope face matched with the end face of the truncation surface of the blade; (3) the portions, within the range of 300-400 mm, of the outer surfaces of theblade and the blade tip sleeve are subjected to polishing and roughing treatment, and the portions, extending from an inner juncture within the range of 300-400 mm in the axial direction of the blade, of the inner surfaces of the blade and the blade tip sleeve are also subjected to polishing and roughing treatment; (4) an adhesive is smeared on the position between the two slope faces, making contact with each other, of the blade tip sleeve and the blade so that primary positioning can be conducted, and then, inner repairing layers are manufactured on the portions, subjected to polishing treatment, of the inner surfaces of the blade and the blade tip sleeve; and (5) outer repairing layers are manufactured on the portions, subjected to polishing treatment, of the outer surfaces of the blade and the blade tip sleeve. According to the fan blade tip repairing method, the structure is simple, operation is convenient, and the repairing quality is high.
