The invention relates to an ultrasonic double-reflection method automatic scanning system for composite material blade detection. The ultrasonic double-reflection method automatic scanning system comprises at least one group of scanning mechanisms, a flexible workbench, a water coupling unit and a blade clamp; each group of scanning mechanism comprises a first multi-axis scanning mechanism, a second multi-axis scanning mechanism, a first control unit, a second control unit, an ultrasonic unit, an imaging unit, a first transducer, a second transducer, a first connector and a second connector; the multi-axis scanning mechanism is connected with the transducers through the connectors, the ultrasonic unit emits broadband narrow-pulse ultrasonic waves and receives and reflects the broadband narrow-pulse ultrasonic waves, and the control unit obtains the scanning positions of the transducers; the blade clamp is fixed to the flexible workbench and clamps the composite material blade, and the water coupling unit is used for providing water coupling between the transducers and the composite material blade. The automatic scanning system adopting the ultrasonic double-reflection method aims to solve problems of low accuracy, reliability and detection efficiency of nondestructive detection of composite material blades.
Description
technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to an automatic scanning system for ultrasonic double-reflection method used for composite material blade testing. Background technique [0002] Composite materials are constantly being used in the aerospace field because of their superior specific performance. Due to quality and safety reasons, the quality inspection and internal defect characterization, evaluation and nondestructive testing of composite parts are very important, especially the quality control and automated nondestructive testing of composite parts in mass production. Composite material blades are currently an important composite material part that has been installed in batches in aero-engines. Ultrasonic is currently the main non-destructive testing method for composite material blades. For manual testing, the ultrasonic reflection method is currently used for testing, with manual scanning testing ...
