Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing of composite materials, in particular to an in-built detection probe boot device for 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 in 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. The conventional ultrasonic longitudinal wave testing technology includes manual contact reflection method, automatic reflection method, manual penetration method, automatic water spray penetration method, etc. The 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 one square foot or a curvature radius greater than one inch and an opening greater than four 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 found in composite wing ribs, spars and stringers of the skin. For the size structure, see the attached drawings of the specification Figure 1 、 Figure 2 , automated detection cannot detect the arc area and flange area, and these areas are usually detected by the manual method.

[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 automatic detection and manual detection are different, different configurations of the detection probe result in different structures and functions of the probe boot assembly, different configurations of the composite materials to be detected 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 a specific probe boot assembly 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 adopts 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, the larger the probe size, and 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 manner. The ultrasonic waves emitted by each element are naturally geometrically focused at the center of the arc of the arc array, and the sound field energy is the strongest at this point. When the curvature center 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 inner side of the fillet or from the outer side of the fillet. Usually, it is detected from the arc surface on the side of the laying tooling, but factors such as the surface state of the detection surface and the size of the detection space still need to be considered. See the attached drawings of the specification. Figure 3 When using the immersion reflection method to detect the fillet area of a composite material, an arc surface phased array probe is adopted, and the detection of an arc area with a certain radius can only be achieved through the 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 water distance of the probe. 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 and opening angle. When there are many types of part opening angles, the number of boot assemblies, probes, and encoders required is large, the cost increases significantly, and the replacement time is long.

[0010] The Chinese invention patent with the application number 201610424401.9 discloses a reference block for ultrasonic testing of the R - angle structure of a composite material. Its artificial defect is placed in the single - curvature arc surface that connects two flat surfaces in the R - angle structure. The artificial defect is rectangular in shape. The long side of the artificial defect is in the same direction as the arc direction of the single - curvature arc surface of the R - angle structure of the reference block, and the short side of the artificial defect is in the same direction as the extension direction of the single - curvature arc surface of the R - angle structure of the reference block. Moreover, the length of the short side is the maximum allowable defect size specified in the corresponding acceptance level of the R - angle structure to be detected. However, this kind of reference block for ultrasonic testing of the R - angle structure of a composite material cannot install an arc - surface phased - array probe, the detection method is slow, it can only detect the arc area with a single - size opening angle. When there are many types of part opening angles, the quantity requirements of the boot assembly, probe, and encoder are large, the cost increases significantly, and the replacement time is long.

[0044] The process of the present probe boot device for detecting the arc area of a composite material part from the inner arc is as follows:

[0046] b. Install the corresponding encoder 17 on this boot assembly and connect it to the ultrasonic phased array instrument;

[0047] c. Fix the composite material profile part to be detected in a water tank, power on the instrument, and open the appropriate detection setting file in the instrument;

[0048] d. Contact plate 15 angular adjustment: Loosen the angular locking screw 13, lean this boot assembly against the inner arc flanging surface of the arc area of the composite material part to be detected, make the two contact plates 15 tightly adhere to the flanges on both sides of the arc, and then tighten the angular locking screw 13;

[0049] e. Horizontally adjust the ultrasonic arc surface phased array probe to the optimal position through the horizontal movement assembly: Loosen the horizontal locking screw 8, gently push the horizontal movement assembly, observe the display of the ultrasonic instrument S, and when it shows a vertically symmetric arc shape, tighten the horizontal locking screw 8. At this time, the symmetric center line of the probe arc surface coincides with the symmetric center line of the part arc;

[0050] f. Radially adjust the ultrasonic arc surface phased array probe to the optimal position through the radial movement assembly: Loosen the radial locking screw 12, rotate the adjustment handle for adjustment until the display of S shows a vertical line shape, and then tighten the radial locking screw 12. At this time, the center of the probe arc coincides with the center of the part arc;

[0051] g. Operate this boot assembly to move and scan for detection along the length direction of the part arc.

[0052] Among them, by designing the installation of the encoder 17, the wheel contact point of the encoder 17 is aligned with the center of the probe width, so that the end detection blind area is zero.

[0053] Among them, the ultrasonic phased array instrument and the detection setting file can both use general equipment and files in this field.

[0054] Among them, phased array probes with different sizes and radii of arc surfaces can be installed, such as: GE 115-000-501, GE115-000-531, 00-011509-IPEX, 00-010925-IPEX. The replacement and disassembly are convenient, which expands the application range of this boot assembly and realizes the detection of different inner arc radii (0.17 - 0.40 inches) of the composite material profile structure.

[0055] Detection of the arc region

[0056] Among them, the opening angle of the contact plate 15 can be adjusted to increase or decrease simultaneously on both sides through the double-gear hinge 14 mechanism.

[0057] Among them, the water distance of the probe can be adjusted along the central symmetry line of the probe to the optimal position and locked. The adjustment is convenient, so that the arc center of the probe coincides with the arc center of the part, ensuring that the sound beam is perpendicular to the arc surface of the part.

[0058] 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, so that the central symmetry line of the probe coincides with the central symmetry line of the arc of the part.

[0059] Among them, the opening angle of the contact plate 15 can be continuously adjusted on both sides according to the opening angle of the part and locked. The opening angle adjustment range is 70 - 142 degrees. The adjustment is convenient, and the center line of the probe remains basically unchanged to expand the use range of the boot assembly.

[0060] Working principle:

[0061] By installing and designing the encoder 17, the contact point of the encoder 17 wheel is aligned with the center of the probe width, so that the blind area at the end is 0. By fixing the encoder 17 on the boot, it is ensured that the roller of the encoder 17 can rub against the inner arc surface of the part and is perpendicular to this surface. The roller contact point is on the center line of the probe width. The distance between the encoder 17 roller and the center line of the inner arc surface of the part is 0.8" - 1.2". The radial adjustment of the probe is realized through the guide groove and screw structure. The probe moves up and down along the radial guide groove so that the arc center of the probe moves along the center line of the probe to coincide with the arc center of the part. Push the lateral movement assembly to make the probe move laterally along the guide groove so that the symmetric center line of the probe arc coincides with the center line of the part arc. Use the gear hinge 14 structure to fix the rotating shaft to fix the contact plate 15 assembly on the base mechanism. The center line connection of the fixed rotating shafts of the gear hinge 14 on each side is parallel to the guide groove and symmetrically distributed with respect to the symmetric center line of the probe arc, so that the opening angle of the contact plate 15 can increase or decrease simultaneously on both sides, and is fixed to a single opening angle, and the position of the opening angle center line remains basically unchanged.

[0062] The beneficial effects of the present utility model are as follows: phased array probes with arc surfaces of different sizes and radii can be installed to expand the usage range of the boot assembly. It is possible to synchronize the encoder wheel to be perpendicular to the part surface and align the wheel contact point with the center of the probe width, achieving a zero blind zone for end detection. The water distance of the probe can be adjusted to the optimal position and fixed along the center symmetry line of the probe, so that the center of the probe arc coincides with the center of the part arc to ensure that the sound beam is perpendicular to the part arc surface. The lateral position of the probe can be adjusted to the optimal position and fixed along the direction perpendicular to the symmetry line of the probe, so that the center symmetry line of the probe coincides with the center symmetry line of the part arc. The opening angle of the contact plate can be adjusted and fixed simultaneously on both sides according to the opening angle of the part, basically keeping the center line of the probe unchanged to expand the usage range of the boot assembly and achieving no blind zone for end detection.

[0063] The above has described in detail one embodiment of the present utility model, but the content is only the preferred embodiment of the present utility model and cannot be considered as limiting the implementation scope of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the patent coverage scope of the present utility model.
