Tail breaking fixture for reducing throat area of turbine guide device and tail breaking tool with same

Abstract

The invention provides a tail breaking fixture for reducing the throat area of a turbine guide device and a tail breaking tool with the same. The tail breaking fixture for reducing the throat area of the turbine guide device comprises a blade basin position clamping device and a blade back pushing and pressing device, wherein the blade back pushing and pressing device is opposite to the blade basin position clamping device, and a blade trough for clamping a turbine guide device blade is formed between the blade basin position clamping device and the blade back pushing and pressing device. According to the tail breaking fixture for reducing the throat area of the turbine guide device and the tail breaking tool with the same, which are disclosed by the invention, the blade basin position clamping device and the blade back pushing and pressing device are arranged. When the turbine guide device blade is arranged in the blade trough between the blade basin position clamping device and the blade back pushing and pressing device, the blade basin of the turbine guide device blade is positioned by the blade basin position clamping device, the blade back pushing and pressing device is acted on the blade back so as to enable the tail edge of the blade to be evenly stressed in a regulation process, and the problems of stress concentration and residual stress generation due to uneven deformation caused by uneven stressing are avoided.

Description

technical field [0001] The invention relates to the field of engine assembly and debugging tools, in particular to a tail breaking fixture for reducing the throat area of ​​a turbine guider and a tail breaking tool with the same. Background technique [0002] Due to manufacturing deviations in the production process of various engine components, the performance of the complete machine cannot meet the design requirements after assembly, and engine performance adjustment is required. The most effective method is to adjust the throat area of ​​the turbine guide. At present, grinding the turbine guide is generally used. The way at the blade throat, the way the turbine guide blades are grouped, or the tail breaking method. The tail-bending method to adjust the throat area of ​​the turbine guide generally uses external force to deform the trailing edge of the blade to change the throat area of ​​the turbine guide. Because this method will not damage the anti-oxidation and anti-co...
