Tail breaking clamp for increasing large throat area of turbine guide vane and tail breaking tool with tail breaking clamp

Abstract

The invention provides a tail breaking clamp for increasing a large throat area of a turbine guide vane and a tail breaking tool with the tail breaking clamp. The tail breaking clamp for increasing the large throat area of the turbine guide vane comprises a blade back clamping device and a blade basin drawing device arranged oppositely to the blade back clamping device, and a blade clamping slot for clamping a blade of the turbine guide vane are formed between the blade back clamping device and the blade basin drawing device. According to the tail breaking clamp for increasing the large throat area of the turbine guide vane and the tail breaking tool with the tail breaking clamp, by arranging the blade back clamping device and the blade basin drawing device, when the blade of the turbine guide vane is arranged in the blade clamping slot between the blade back clamping device and the blade basin drawing device, the blade back clamping device locates the blade back of the blade of the turbine guide vane and the blade basin drawing device acts on the blade basin, so that the blade is uniformly stressed in the trailing edge adjusting process, and the problems of uneven deformation, concentrated stress and residual stress, caused by uneven stress, are effectively prevented.

Description

technical field [0001] The invention relates to the field of engine assembly and debugging tools, in particular to a tail breaking fixture for increasing 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-...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a tail-cracking jig and a tail-cracking tool with which the force is uniform in the process of adjusting the blade trailing edge to increase the throat area of ​​the turbine guider, so as to solve the problem of common calipers in opening the throat of the turbine guider. The problem of uneven deformation caused by uneven force in the process of surface area
