Abstract
The invention discloses a protection device used for assembling a rotor blade with convex shoulders, and belongs to the technical field of assembling processes of rotor blades with convex shoulders of aero-engines. The protection device used for assembling the rotor blade with the convex shoulders comprises a protection part, a clamping opening is formed in one end of the protection part, and a tightening part is arranged at the other end of the protection part. The clamping opening is used for being fixed to the convex shoulder root on the rotor blade with the convex shoulders, and the tightening part is used for being detachably connected with the air inlet edge of the rotor blade with the convex shoulders. The protection part, the clamping opening and the tightening part are integrally connected. The protection part is of a protection plate structure, the tightening part is of an inclined plane structure, and the protection part and the tightening part form a closing clamp-shaped body. According to the protection device used for assembling the rotor blade with the convex shoulders, the protection device can be completely attached to the molded surface of the blade, direct contact between a blade basin convex shoulder and a blade back convex shoulder is avoided, and finally zero-damage assembling of the rotor blade with the convex shoulders is achieved.
