Embodiment

[0043] Please refer to figure 1 with figure 2 A splash protection assembly for blade electron beam welding, including: the first stopper 10 and the second stop 20. After the first stopper 10 and the second stopper 20 are connected to each other, the clamping space 30 is formed to hold the front side of the air engine blade 70, the first stop 10 and the second stop 20 are disposed. There are multiple baffles for protection for blade 70 and splash protection.

[0044] Please refer to Figure 1 to 3 The first stopper 10 includes a first side 11, a second side 12, a third side surface 13, and a concave side 14 in sequentially disposed. The first baffle 41 and the second baffle 42 are respectively provided at the top of the first side surface 11 and the second side surface 12. The concave surface 14 is the side surface of the depression, is provided with the leaf back of the blade 70, and a third baffle 43 is provided at a position close to the concave surface side 14, in the present em...

Abstract

The invention discloses a splash protection assembly for blade electron beam welding and a blade welding method, and belongs to the technical field of aero-engine blade welding. The splash protection assembly for blade electron beam welding comprises a first blocking piece and a second blocking piece which are connected with each other. A clamping space used for clamping a blade is formed between the first blocking piece and the second blocking piece. Outer side protection layers are arranged on the outer sides of the first blocking piece and the second blocking piece, inner side protection layers are arranged on the inner sides of the first blocking piece and the second blocking piece around the clamping space, a splash protection space is formed between the outer side protection layers and the inner side protection layers, and a blade protection space is formed on the inner sides of the inner side protection layers. The blade is protected through the inner side protection layers, splash generated by welding is prevented through the outer side protection layers and the inner side protection layers, and therefore the influence of splash on the blade is greatly reduced, and the quality of the blade after electron beam welding is improved.

Description

Technical field [0001] The present invention relates to the field of air engine blade welding technology, and more particularly to splash protection assemblies and blade welding methods for blade electron beam welding. Background technique [0002] In a certain air engine produced, the 0 ~ 3 stator assembly is an electron beam welding structure, which requires 120 circumferential circumference to be welded to the casing using an electron beam weld, and requires no splash on the blade after welding. Electronic beam welding generated a splash is an objective phenomenon that is recognized in the industry, which can only protect and weld treatment and post-weld treatment, because the air engine blade surface is high, and polishing will affect the surface quality of the blade. Inventive content [0003] It is an object of the present invention to provide a splash protection assembly and a blade welding method for blade electron beam welding to solve the problem of surface quality of ...
