Problems solved by technology

[0003] The extremely harsh service environment and foreign object damage of aero-engines will cause large-scale failure of the blades, and the cost of overall replacement is high. The use of repair and replacement technology is an inevitable choice to repair the blisk blades and prolong the service life of the engine blisk blades; but the engine The disc structure requires high reliability and precision, and the blade is a thin-walled structure. The difference in the compensation structure used in the replacement process will cause the difference in the overall performance of the repaired blade

Embodiment 1

[0029] like figure 1 As shown, in this embodiment, the compensating body selected for retaining the surface of the blade as a spatial planar structure replacement and repair is a single-structure compensating body.

[0030] refer to figure 2 There is a card slot 1 in the compensation structure of the single body. The card slot 1 is used for inserting the reserved blade 11 after the blade is cut. It is attached to the upper bottom surface of the card slot 1, and the lower surface of the retained blade extending into the card slot 1 is attached to the lower bottom surface 8 of the card slot.

[0031] Wherein, the cutting surface of the reserved blade 11 and the side 6 of the slot are a pair of butt joint surfaces, the upper surface of the reserved blade 11 and the upper bottom surface 7 of the slot 1 are a pair of overlapping surfaces, and the lower surface of the reserved blade and the lower bottom surface 8 of the slot 1 are The other pair of overlapping surfaces forms an o...

Embodiment 2

[0037] like image 3 and Figure 4 As shown, in this embodiment, the compensation body 1 used to retain the blade surface as a space surface structure replacement and repair is selected, which is a multi-body structure compensation body.

[0038] The multi-body structure compensator includes a first overlapping body 2, a second overlapping body 3 and a docking body 4, wherein the second overlapping body 3 and the docking body 4 are integrated, and the first overlapping body 2 and the docking body 4 There are welds 5 in between. One side of the weld 5 is the side surface 9 of the first overlapping body, and the other side is the side surface of the butt joint body. The multi-body structure compensation body is provided with a card slot 1, the upper side wall of the card slot 1 is the first overlapping body 2, the lower side wall is the second overlapping body 3, and the rest of the multi-body structure compensation body is the butt joint body 4.

Abstract

The invention discloses a lap-to-composite integrated compensator for engine disk damage, comprising a first lap body, a second lap body and a butt joint, the second lap body is located on the first lap body Below, the same side of the first overlapping body and the second overlapping body is connected with a docking body, and the first overlapping body, the second overlapping body and the docking body are enclosed to form a draw-in groove, and the draw-in groove is used When the reserved blade is inserted, the cutting surface of the reserved blade is attached to the side of the slot, and there is a welding seam between the first overlapping body and the abutting body. The lap / butt joint method can effectively avoid welding defects such as air holes and undercuts.

Description

technical field [0001] The invention relates to a lap / pair composite integrated compensator used for engine disk damage, in particular to a compensator with a margin and a processable compensator. Background technique [0002] With the development of aero-engine design technology, the dimensional accuracy requirements of aero-engine blades are getting higher and higher. Turboshaft engines rely entirely on gas flow to generate thrust. With the continuous improvement of thrust-to-weight ratio / power-to-weight ratio, structural reliability, and accuracy consistency requirements of aeroengines, the harsh service environment is likely to cause disk failure. [0003] The extremely harsh service environment and foreign object damage of aero-engines will cause large-scale failure of the blades, and the cost of overall replacement is high. The use of repair and replacement technology is an inevitable choice to repair the blisk blades and prolong the service life of the engine blisk bl...
