Description

Technical Field

[0001] The utility model relates to the field of phased array nondestructive testing, in particular to an anti-wear base, a wedge block and a device for phased array nondestructive testing. Background Art

[0002] Phased array nondestructive testing (NDT) is an advanced nondestructive testing technology primarily used for integrity testing of materials and components. It works by using a phased array probe to transmit ultrasonic waves toward the material or component being tested and receiving the reflected ultrasonic signals. By analyzing these signals, information such as internal defects and thickness can be determined. Compared to traditional ultrasonic testing, phased array NDT offers higher accuracy and efficiency. The main advantages of phased array NDT include high precision, high efficiency, low cost, and non-destructiveness. It can be widely used to test a wide range of materials, including metals, non-metals, and composites. Phased array NDT is also applicable to various industrial sectors, such as aerospace, petrochemicals, and electric power.

[0003] During phased array testing, a trapezoidal wedge is used. It is generally made of plexiglass, and is trapezoidal when viewed from the side. It contains sound-absorbing material, and the geometric dimensions of the bottom surface of the wedge are generally 20-30mm. The wedge is used to allow the ultrasonic beam to pass through the inclined surface of the trapezoidal wedge and then be emitted from the opposite side of the inclined surface to scan the part to be inspected. During testing, in order to make the ultrasonic beam fully scan the part to be inspected, the ultrasonic beam emitting device will move along the workpiece to be inspected with the wedge to perform a comprehensive scan of the part to be inspected. Therefore, the wedge will be subject to a certain degree of wear and tear on the workpiece to be inspected. Severe wear of the wedge will cause its geometric dimensions to change. When a workpiece to be inspected has a certain amount of detection, the incident direction of the ultrasonic beam will be inconsistent with that at the beginning of calibration, and then the echo direction will be inconsistent with that at the beginning of calibration, thereby affecting the accuracy of the test results, or multiple calibrations must be performed to ensure the accuracy of the test.

[0004] Therefore, those skilled in the art are committed to developing a wear-resistant base, wedge block and device for phased array non-destructive testing. Utility Model Content

[0007] A first limiting protrusion is provided on one end of the first anti-wear strip away from the connecting strip, and the first limiting protrusion extends along a side away from the first anti-wear strip;

[0008] A second limiting protrusion is provided on one end of the second anti-wear strip away from the connecting strip, and the second limiting protrusion extends along a side away from the second anti-wear strip.

[0009] Preferably, the first anti-wear strip, the second anti-wear strip and the connecting strip have square cross-sections.

[0013] Preferably, the bottom of the base is located below the bottom of the detection block.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, in the description of the present invention, the terms "upper," "lower," "left," "right," "inner," "outer," and the like, indicating directions or positions, are based on the directions or positions shown in the accompanying drawings and are intended solely for the purpose of facilitating and simplifying the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific manner. Therefore, they should not be construed as limiting the present invention. The terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figure 1-5 As shown, a wear-resistant base for phased array nondestructive testing includes a base 1. The cross-section of the base 1 is a rectangular structure with one side open. The base 1 includes a first wear-resistant strip 11, a second wear-resistant strip 12 and a connecting strip 13. In this embodiment, the first wear-resistant strip 11, the second wear-resistant strip 12 and the connecting strip 13 are square in cross-section and are made of 60% polytetrafluoroethylene and 40% brass. In other embodiments, graphene, high manganese steel and other wear-resistant or low-friction materials can also be used.

[0024] The first anti-wear strip 11 is provided with a first limiting protrusion 11a at one end away from the connecting strip 13, and the first limiting protrusion 11a extends along the side away from the first anti-wear strip 11. The second anti-wear strip 12 is provided with a second limiting protrusion 12a at one end away from the connecting strip 13, and the second limiting protrusion 12a extends along the side away from the second anti-wear strip 12. In this embodiment, the first anti-wear strip 11, the second anti-wear strip 12, and the first limiting protrusion 11a and the second limiting protrusion 12a of the connecting strip 13 are all integrally formed to ensure their strength in use.

[0025] The present invention also provides a wedge block for phased array nondestructive testing, including an anti-wear base for phased array nondestructive testing as described above, and also includes a detection block 2. The detection block 2 is generally made of organic glass, and is trapezoidal in side view, and contains sound-absorbing material. The geometric dimensions of the bottom surface of the wedge block are generally 20-30 mm. In this embodiment, a first clearance groove 2a and a second clearance groove 2b are respectively opened on opposite sides of the bottom of the detection block 2. The first anti-wear strip 11 is clamped with the first clearance groove 2a, and the second anti-wear strip 12 is clamped with the second clearance groove 2b. One side of the first limiting protrusion 11a abuts against the side wall of the detection block 2. The second limiting protrusion 12a also abuts against the side wall of the detection block 2 to prevent the detection block 2 from sliding. In this embodiment, the bottom of the base 1 is located below the bottom of the detection block 2, that is, the bottom of the base 1 extends out of the bottom of the detection block 2. The side wall of the base 1, the bottom of the detection block 2 and the workpiece to be detected constitute a cavity with an open side. The bottom of the detection block 2 does not directly contact the workpiece to be detected, and no friction is generated between the two, thereby effectively protecting the detection block 2, reducing its loss, ensuring detection accuracy, reducing the number of calibrations required when a type of workpiece has a certain detection amount, and reducing labor intensity.

[0026] The utility model also provides a phased array nondestructive testing device, comprising any of the above phased array nondestructive testing wedges.

[0027] When in use, the detection block 2 is inserted into the base 1, the first anti-wear strip 11 is engaged with the first make way groove 2a, the second anti-wear strip 12 is engaged with the second make way groove 2b, and one side of the first limiting protrusion 11a and one side of the second limiting protrusion 12a abut against the side wall of the detection block 2 to fix the detection block 2 and prevent it from sliding. Since the bottom of the detection block 2 is not in direct contact with the part to be detected, almost no friction loss is generated, which increases the service life of the detection block 2 and reduces the cost of use. In addition, the structure is simple and has great promotion value.

[0028] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
