Abstract

The invention relates to the field of aviation engine maintenance equipment, in particular to a rotor blade boss energy storage spot welding repair clamping device and a clamping method. The device and the method have a quick clamping and disassembling function, have a clamping force maintaining function and simultaneously ensure that the protective belt of a low-pressure compressor rotor blade boss is in good contact with a workbench during energy storage spot welding to form a stable current loop. The device comprises an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are rotationally connected through mounting pins arranged in an upper clamping plate mounting hole and a lower clamping plate mounting hole, torsion springs are arranged outside the mounting pins in a sleeving mode, the upper clamping plate and the lower clamping plate are driven by the torsion springs to be clamped, and the upper clamping plate and the lower clamping plate are made of red copper. The device and the method have a quick clamping and disassembling function, ensure the production efficiency and shorten the production period. The device and the method are particularly suitable for the rotor blade boss energy storage spot welding repair process.

Description

technical field [0001] The invention relates to the field of aero-engine maintenance equipment, in particular to a clamping device and a clamping method for energy storage spot welding repair of a boss of a rotor blade. Background technique [0002] Low-pressure compressor rotor blades are the key components of the engine. After the engine has been used for a life cycle, the bosses of the low-pressure compressor rotor blades are worn and cannot meet the requirements of use. It is necessary to induction braze the worn parts of the bosses to restore the wear-resistant layer. . The recovery process requires the use of stored energy spot welding to wrap the protective tape around the boss. The energy storage spot welding needs to form a current loop, and the blade body is not allowed to contact discharge, only the blade tenon and the workbench can be contacted. The tenon of the blade is characterized by an acute angle, and it is difficult to form a large-area contact with the ...
