Metal propeller shot-blasting repairing device

Abstract

The invention provides a metal propeller shot-blasting repairing device which comprises a main body part, wherein the main body part is provided with a supporting frame assembly; propeller rotating parts arranged at the two ends of the main body part and used for supporting the two sides of metal propellers; a spray gun adjusting and automatic feeding part arranged in the middle of the main body part and used for performing shot blasting on the metal propeller; a shot storage and protection part connected with the spray gun adjusting and automatic feeding part and used for storing shots required by single shot blasting; and an auxiliary supporting part used for supporting the propeller girder in an auxiliary manner under the condition that the head part or the tail part of the propeller girder needs to be repaired. The provided shot-blasting repairing device can be quickly adjusted, is convenient and fast to operate, is reliable to use and can greatly improve the production efficiency.

Description

technical field [0001] The application belongs to the technical field of helicopter metal blade maintenance, and in particular relates to a metal blade repair shot peening device. Background technique [0002] After a period of use, metal propellers may suffer surface pitting or scratch damage. In view of these situations, it is necessary to repair the propellers and carry out supplementary shot peening on the propeller girders to eliminate the surface damage of the girders and improve the surface strength of the metal girders to ensure that the propellers can be restored to use. [0003] The existing metal girder repair shot peening work is to place the reworked blade on the bracket, push it outside, manually wear protective clothing and glasses, and repair the damaged part. This working method is labor-intensive, and the damage at different positions requires constant changing of the position of the blades to perform shot peening repairs, and the operation is cumbersome. ...

AI Technical Summary

Problems solved by technology

This way of working is labor-intensive, and the damage at different positions requires constant changing of the position of the blades to perform shot peening repairs, and the operation is cumbersome.

[0004] And the feed speed of rework shot peening needs to meet the process requirements of 570mm / min±10%, and the distance between the nozzle of the spray gun and the paddle also has a fixed requirement, and manual operation cannot meet the requirements of this parameter, which may lead to unqualified product rework
