Abstract

The invention discloses a special shape follow-up ultrasonic detectiondevice for the wall thickness of a hollow blade and a detection method thereof. A display frame is connected to one end of a probe connecting plate; the probe connecting plate is connected with a grinding head part on a machine tool or a robot through an L-shaped connecting block and a machine tool grinding head positioning block; an ultrasonic probe is connected to the probe connecting block; a probe shell and a porous flexible body are arranged on the periphery of the ultrasonic probe; relative movement between the ultrasonic probe and the probe shell is realized through an air cylinder; and a spring is arranged between a cavity of the ultrasonic probe and a probe needle, one end of a coupling agent conveying pipe is connected into a coupling agent container, the other end of the coupling agent conveying pipe is connected with the probe shell, a coupling agent is stored in the coupling agent conveying pipe, and the space between the probe and a blade is filled with the coupling agent through a porous flexible body. The production cost and the time cost of a hollow blade can be effectively reduced, the development of the hollow blade process is further promoted, and the batch production of a hollow blade is promoted.

Description

technical field [0001] The invention relates to the technical field of measurement of aeroengine blades, in particular to a special device for the conformal ultrasonic detection of the wall thickness of hollow blades and a detection method thereof. Background technique [0002] Advanced aero-engines are strategic high-tech products related to national military security and national economic development. They are the "crown jewels" in the high-end manufacturing field, and their processing and manufacturing capabilities are a symbol of the country's comprehensive strength. The lightweight and high-strength large-size wide-chord shoulderless titanium alloy hollow fan blades provide nearly 80% of the engine's thrust for the engine, and its processing quality directly affects the service performance and life of the engine, which is the core key to improving the engine manufacturing level. Accurately obtaining the actual size state of the personalized hollow fan blade blank after ...
