Abstract

A wear detection tool for a blade shroud face, characterized in that it includes a compression handle I, a pull rod I, a rotating shaft, a measuring chuck I, a blade shroud front edge, a blade shroud trailing edge, a measuring chuck II, a measuring gauge head, a clamping Frame, measuring table, knurled screw, bracket, pin shaft, stabilizing groove, pull rod II, compression handle II, tension spring; compression handle I and measuring chuck II are integrated structure, compression handle II and measuring chuck I is an integral structure, and the two are hinged by a rotating shaft; a pull rod I is installed on the inside of the tail of the compression handle I, and a pull rod II is installed on the inside of the tail of the compression handle II; a tension spring is installed between the pull rod I and the pull rod II; There is a stabilizing groove on the outside of the middle part of the tight handle II; a pin shaft is installed on the outside of the middle part of the tight handle II. The invention has the advantages of reliable structure, simple use, accurate, reliable and fast data measurement, disassembly and assembly, and can be widely used in the wear detection of the crowned blade working face.

Description

technical field [0001] The invention relates to the field of detection devices for the wear amount of the shroud working surface of the turbine rotor shrouded blade of a gas turbine or an aeroengine, and in particular relates to a wear detection tool for the working surface of the blade shroud. Background technique [0002] At present, the blade crowns of engine and gas turbine rotor blades are widely designed with sawtooth crown structure. When the blade is working, the tight fit of the working surface can suppress the rotor vibration and enhance the rigidity of the rotor. The sawtooth crown is generally composed of tenon, blade body and blade crown. The crown has a working surface and a non-working surface. When the blade is assembled, there is tightness on the working surface and a gap on the non-working surface. In order to ensure that the working surface with blade tightness has a reasonable tightness during engine assembly, it is necessary to measure the working surfac...
