Abstract

The invention provides a detection device for turbine blades of an aircraft engine, and relates to the technical field of turbine detection, and the detection device comprises an installation supporting part which is in sliding connection with a driving butt joint device; a movable positioning device is rotationally connected to the driving docking device; the movable positioning device is in threaded connection with a positioning adjusting device; a brake device is fixedly connected to the mounting support part; a reverse moving part is connected to the mounting supporting part in a sliding manner; the reverse moving part is rotationally connected with a blade pitch measuring device; the blade pitch measuring device is slidably connected with a circle of detection stirring pieces in an annular array mode. The blade pitch can be rapidly and comprehensively measured, meanwhile, linkage vibration detection can be achieved, data are more comprehensive, and the coaxial maintaining effect is better; the problems that an existing aircraft engine turbine blade detection device is not provided with a blade pitch auxiliary detection device, the detection efficiency is low, locking positioning cannot be achieved, and linkage vibration detection cannot be achieved are solved.

Description

technical field [0001] The invention relates to the technical field of turbine detection, in particular to a detection device for turbine blades of an aircraft engine. Background technique [0002] In the actual aircraft manufacturing industry, the aircraft engine has always been an important driving component, among which the aircraft engine turbine plays an important role in flight safety and other aspects. At this time, a good aircraft engine turbine blade detection device is particularly important. important. [0003] However, as far as the current detection device of the turbine blade of an aircraft engine is concerned, there is no auxiliary detection device for the blade pitch, the detection efficiency is low, the error is large, the locking and positioning cannot be realized, the turbine installation is inconvenient, the stable connection cannot be realized, the detection is not stable enough, and the data Errors are easily generated, linkage vibration detection cann...
