Automatic whole-disc assembling device for interlocking type rotor blades of aero-engine

Abstract

The invention discloses a whole-disc automatic assembling device for interlocking type rotor blades of an aero-engine. The whole-disc automatic assembling device comprises a main support, a blade crown outer circle tool, a tenon positioning mechanism, a blade crown press-fit mechanism, a wheel disc lifting mechanism, a roller press-fitting mechanism and a mortise guide mechanism. A plurality of through holes are formed in the top end of the blade crown outer circle tool. The blade crown pressing mechanism comprises a blade crown pressing part and a blade crown driving part; the wheel disc lifting mechanism comprises a wheel disc support, a spiral lead screw lifter and a motor; the roller press-fitting mechanism comprises a roller pressing piece and a main shaft. The automatic assembling device has the beneficial effects that the blade crown and the tenon are positioned and clamped through the tenon positioning mechanism and the blade crown outer circle tool, whole-disc automatic assembling of the interlocking type rotor blades is achieved, the problems that in the traditional manual piece-by-piece assembling process of the interlocking type rotor blades, the last blade does not have enough allowance, and assembling is difficult are solved, and the assembling efficiency of the interlocking type rotor blades is improved. Potential damage in the assembling process of the interlocking type rotor blade is reduced, the assembling precision and efficiency of the interlocking type rotor blade are improved, and meanwhile the labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to an assembly device, in particular to an aero-engine interlocking rotor blade whole disk automatic assembly device, which belongs to the technical field of aero-engine blade assembly. Background technique [0002] At present, in the engine manufacturing industry, the traditional engine rotor blade assembly is still dominated by traditional manual assembly. For the interlocking rotor blades, there is not enough margin for the last blade in the traditional manual assembly process, and the assembly needs to be completed by brute force knocking. , it is easy to cause potential quality hidden dangers such as blade loss, blade crown misalignment, large assembly stress, cracks, etc., which affect the assembly quality. In addition, the traditional blade assembly efficiency and quality depend on the operator, which is inefficient and labor-intensive. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a...

[0002] At present, in the engine manufacturing industry, the assembly of traditional engine rotor blades is still dominated by traditional manual assembly. For interlocking rotor blades, there is not enough margin for the last blade in the traditional manual piece-by-piece assembly process, and brute force is required to complete the assembly. , easily lead to potential quality hazards such as blade loss, crown misalignment, large assembly stress, and cracks, which affect assembly quality. In addition, the efficiency and quality of traditional blade assembly depend on operators, which is low in efficiency and labor-intensive
