Aero-engine blisk-blade welding repair clamping device

Abstract

The invention relates to an aero-engine blisk-blade welding repair clamping device which is characterized in that a blisk assembly clamping system is installed on a platform linear lifting system and can ascend and descend along with the platform linear lifting system; and a blade flexible clamping system is located on the top of the platform linear lifting system and can clamp blades of the blisk in the X direction and the Y direction. According to the aero-engine blisk-blade welding repair clamping device provided by the invention, clamping of the blisk is achieved through meshing of end teeth, so that high stability is achieved; blisks with different specifications can be clamped by changing the size of the end teeth, so that diversified adjustment of clamping process parameters is achieved; a single-layer clamping chain is adopted as a clamping tool and a heat dissipation device of the blades, and the position of a clamping block and the clamping pressure of the clamping chain are adjusted by controlling the air supply amount of a clamping air cylinder, so that flexible clamping is achieved, and effective heat dissipation is achieved; and a motor is adopted to drive the end teeth to rotate, and the platform is manually lifted, so that multi-phase adjustment of the blisk and the blades is achieved, the precision of the installation position of the clamping chain clamp is guaranteed, and continuous welding repair between the different blades is achieved.

Description

technical field [0001] The invention belongs to the technical field of aviation maintenance, and in particular relates to a clamping device for integral blisk-blade welding repair of an aeroengine. Background technique [0002] With the development of high-performance aero-engine manufacturing technology, in order to simplify the engine structure and improve aerodynamic efficiency at the same time, the application of blisks (blades-discs) is becoming more and more extensive. The industrial sector focuses on technical challenges. In various manufacturing and repairing technical routes, the clamping and positioning device of the overall blisk is the core basis for realizing precise and flexible machining, which is of great significance for improving the machining accuracy of the blisk-blade. [0003] So far, there have been various clamping devices for blade welding repair. Wang Zhiping developed a flexible fixture for welding and repairing liftable blades. The clamping heig...
