Problems solved by technology
In recent years, in order to meet the manufacturing needs of large-load and high-performance new models, composite material technology has developed rapidly, and new materials, new structures, and new processes have emerged continuously. Conventional ultrasonic technology has been difficult to meet the testing requirements of composite materials.
At present, in actual non-destructive testing, the main problem is that when the surface to be tested is a curved surface, the detection probe cannot float along the surface to be tested to achieve the best detection effect

Abstract
The invention provides a curved surface self-adaptive device used for ultrasonic testing, comprising a telescopic mechanism, a floating mechanism and a detection probe, the floating mechanism is fixedat the front end of the telescopic mechanism, the detection probe is fixed in the floating mechanism, the telescopic mechanism moves back and forth when being driven by an external power driving part, and the floating mechanism floats adaptively according to change of curvature of a to-be-tested surface, so that the detection probe always clings to and aligns with a normal direction of the curvedsurface, and detection is completed. The device provided by the invention can be applicable to tracking of various complex surfaces, and alignment of the detection probe with the normal direction ofthe to-be-tested curved surface can be realized by virtue of a mechanical structure, so that detection effect is better.
Description
technical field [0001] The invention relates to a floating device, in particular to a curved surface self-adaptive device for ultrasonic testing of composite materials. Background technique [0002] Composite materials are one of the main types of materials used in the design and manufacture of modern aerospace vehicles. During the manufacture and use of composite parts, ultrasonic testing is a key technology to detect component defects and damage and evaluate its safety performance. In recent years, in order to meet the manufacturing needs of large-load and high-performance new machine parts, composite material technology has developed rapidly, and new materials, new structures, and new processes have emerged continuously. Conventional ultrasonic technology has been difficult to meet the testing requirements of composite materials. At present, in actual non-destructive testing, the main problem is that when the surface to be tested is a curved surface, the detection probe ...
