Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing of composite materials, in particular to a probe boot device for detecting the arc area of composite materials. Background Art

[0002] In the prior art, due to its excellent designability, fatigue resistance, corrosion resistance and high weight reduction efficiency, composite materials have become the necessary materials for various advanced aircraft structures. The application proportion of composite materials on advanced aircraft has been increasing year by year. In the production stage of composite components, the non-destructive testing of composite materials mainly adopts conventional ultrasonic longitudinal wave testing technology and ultrasonic longitudinal wave phased array testing technology. Conventional ultrasonic longitudinal wave testing technology includes manual contact reflection method, automatic reflection method, manual penetration method, automatic water spray penetration method, etc. Ultrasonic longitudinal wave phased array technology includes manual contact reflection method, automatic reflection method, manual penetration method, automatic water spray penetration method, etc. Usually, for plane or curved surface parts with an area greater than 1 square foot or a curvature radius greater than 1 inch and an opening greater than 4 inches, an automatic penetration large ultrasonic C-scan system is used for detection to improve the detection efficiency; for complex-shaped composite parts that do not meet the above conditions, due to the limitation of shape or detection space, automated detection cannot achieve complete ultrasonic coverage of the component, and generally a manual ultrasonic conventional system or phased array system is used for detection. For example, small-radius arcs and narrow flanges are commonly present in composite wing ribs, spars and stringers of panels. For the large and small structures, see the attached drawings of the specification Figure 1 、 Figure 2 , automated detection cannot detect the arc area and flange area, and for these areas, manual methods are usually used for detection.

[0003] There are various ultrasonic detection methods for composite materials. However, no matter which detection method is used, a suitable probe boot assembly must be used to achieve effective detection of composite components. Different detection methods result in different structures and functions of the probe boot assembly. For example, the structures and functions of the contact method boot and the immersion method boot are different, the structures and functions of the immersion method boot and the water spray method boot are different, the structures and functions of the boots for automated detection and manual detection are different, different configurations of the detection probes lead to different structures and functions of the probe boot assembly, different configurations of the composite materials to be detected also result in different structures and functions of the probe boot assembly, and the structures and functions of the probe boots for detecting flat surfaces, convex surfaces and concave surfaces are different. Designing and manufacturing specific probe boot assemblies according to the detection method, probe configuration and part configuration is the key to the successful implementation of ultrasonic detection of composite materials.

[0004] The ultrasonic phased array manual immersion reflection method is the development direction for detecting the arc area of composite parts. Its detection principle is described as follows: When detecting the fillet area of a composite part, an ultrasonic phased array probe usually uses a concave arc surface linear array probe. A typical configuration is 36 - 64 wafers, with a frequency of 3.5 MHz and an arc radius of 0.5 - 1.5 inches. The more the number of wafers, the larger the arc radius, and the larger the probe size. The larger the arc radius of the part, the more wafers and the larger the arc radius of the probe are required. The elements of the concave arc surface linear array probe are arranged in an arc. The ultrasonic waves emitted by each element are naturally geometrically focused at the center of the arc of the arc array, where the sound field energy is the strongest. When the center of curvature of the workpiece arc coincides with the center of the probe arc, during scanning, each element is directly excited without any delay processing, and the ultrasonic beam of each element can be made to be incident at 90 degrees to the surface of the part fillet, as if performing a planar detection, greatly reducing the energy loss of the ultrasonic waves before they enter the workpiece surface. The entire arc area can be covered in one scan. During the production process of composite materials, this kind of fillet detection can be carried out from the inside or the outside of the fillet. Usually, it is carried out from the arc surface on the side of the laying tooling. See the attached Figure 3 When using the immersion reflection method to detect the fillet area of composite materials, an arc surface phased array probe is used, and the detection of an arc area with a certain radius can only be achieved through an arc surface delay boot assembly.

[0005] However, the probe boot device in the prior art has the following disadvantages:

[0006] 1) It can only install an arc surface phased array probe of one size and radius, increasing the number of boot assemblies;

[0007] 2) It can install a distance encoder, but its contacts are generally not aligned and synchronized with the phased array probe, resulting in a detection blind area problem at the end of the part;

[0008] 3) It can only adjust and fix the probe water distance. When the arc of the part is irregular, it is very difficult to ensure that the probe position is in the best detection position, and the quality of the detection image deteriorates;

[0009] 4) It can only detect an arc area with a single size of opening angle. When there are many types of part opening angles, the quantity requirements for boot assemblies, probes, and encoders are large, the cost increases significantly, and the replacement time is long.

[0010] The Chinese invention patent with the application number 201210014624.X discloses an ultrasonic transducer fixture for detecting the convex R area of a composite material, which consists of a guiding frame, a transducer seat and a locking handle; the guiding frame is composed of two guiding plates with the same structure, two connecting pins and four screws. However, this ultrasonic transducer fixture for detecting the convex R area of a composite material can only install an arc surface phased array probe of one size and radius, increasing the number of boot components. It can install a distance encoder, but its contacts are not aligned and synchronized with the phased array probe, resulting in a detection blind area problem at the end of the part. It can only adjust and fix the water distance of the probe. When the arc of the part is irregular, it is difficult to ensure that the probe position is in the best detection position, and the quality of the detection image decreases. It can only detect the arc area with a single large and small opening angle. When there are many types of part opening angles, the number of boot components, probes and encoders required is large, the cost increases significantly, and the replacement time is long.

They are convenient to replace and disassemble, expanding the application range of this boot assembly, and enabling the inspection of arc regions with different outer arc radii (0.1 - 1.0 inches) of composite material profiles.

[0059] Among them, a water-immersed miniature distance encoder 21 (ENC1-10-DE) can be installed and ensure that the wheel of the distance encoder 21 is perpendicular to the part surface, and the wheel contact point is aligned and synchronized with the center of the probe width, achieving a blind zone of 0 for end detection. The distance between the wheel and the center line of the probe is as small as possible to ensure the inspection of the arc region of the composite material profile structure with a flanging width of 1 inch or more than 1 inch. It is convenient to replace and disassemble, expanding the application range of this boot assembly.

[0060] Among them, the water distance of the probe can be coarsely and finely adjusted along the center symmetry line of the probe to the optimal position and locked. The adjustment is convenient, making the arc center of the probe coincide with the arc center of the part, and ensuring that the sound beam is perpendicular to the arc surface of the part.

[0061] Among them, the lateral position of the probe can be adjusted along the vertical direction of the symmetry line of the probe to the optimal position and locked. The adjustment is convenient, making the center symmetry line of the probe coincide with the center symmetry line of the part arc.

[0062] Working principle:

[0063] Through the cooperation of the frame component, the radial component and the contact component, a probe boot device is jointly formed, which can install phased array probes with different sizes and radii of arcs to expand its uses. The ultrasonic phased array probe 2 is installed on the fine-tuning slider 11 by screws. The frame component adjusts the lateral positions of the radial component and the ultrasonic phased array probe 2, and the radial component adjusts the radial position of the ultrasonic phased array probe 2, so that the center of the probe arc and the symmetric center line coincide with the center of the part arc and the center line. The double-gear hinge 18 mechanism is used to realize that the opening angle of the contact plate 16 can be adjusted to become larger or smaller simultaneously on both sides, and the position of the opening angle center line remains basically unchanged.

[0064] The beneficial effects of the present invention are that the cooperation of the frame component and the radial component can meet the installation requirements of phased array probes with different sizes and radii of arc surfaces, and can ensure that the encoder wheel is perpendicular to the part surface and the wheel contact point is aligned with the center of the probe width synchronously, realizing no blind area in the end detection. It can make the center of the probe arc and the center symmetry line coincide with the center of the part arc and the center symmetry line, ensuring that the sound beam is perpendicular to the part arc surface. There is a contact component, which can adjust the opening angle of the contact plate to become larger or smaller on both sides simultaneously with the size of the part opening angle and fix it, so that the center line of the probe remains unchanged, so as to expand the use range of the boot component.

All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
