Description

Technical Field

[0001] This utility model relates to an articulated ultrasonic probe device. Background Technology

[0002] Ultrasonic testing technology is a common technique for detecting internal defects in components, widely used in both metallic and non-metallic materials. Chinese Patent Application No. 202311326130.X discloses a probe device and method for in-situ ultrasonic flaw detection of blades. The probe device includes a surface wave ultrasonic probe connected to an ultrasonic flaw detector via a cable, a handheld rod, and a syringe. One end of the handheld rod has a handle; the surface wave ultrasonic probe is mounted on the end of the handheld rod furthest from the handle. During flaw detection, the surface wave ultrasonic probe can be inserted into a narrow area to inspect the blade by holding the handle. However, in this in-situ ultrasonic flaw detection probe device, the ultrasonic probe and the extension rod are rigidly connected. When there is an obstruction near the detection point, the extension rod slightly adjusts its angle to avoid the obstacle, simultaneously rotating the probe. This alters the contact between the probe's detection surface and the workpiece, making contact coupling difficult and hindering reliable ultrasonic penetration into the workpiece. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] Another objective of this invention is to provide an articulated ultrasonic probe device. The probe is delivered to the surface to be inspected via a handheld lever. The articulated assembly can adapt to the position and angle of the surface to be inspected, enabling reliable inspection and effectively improving the coupling effect between the flaw detection contact surface and the surface to be inspected.

[0005] To achieve these objectives and other advantages according to the present invention, an articulated ultrasonic probe device is provided, comprising:

[0006] Handheld stick;

[0007] The probe includes a housing; a piezoelectric crystal disposed at the flaw detection contact surface of the housing; and a cable with one end connected to the piezoelectric crystal and the other end extending outward from the housing.

[0008] The joint assembly includes a pair of through holes corresponding to the side wall of the housing; a shaft tube, which is disposed inside the housing through the pair of through holes, with the extension direction of the shaft tube parallel to the plane of the flaw detection contact surface, and the shaft tube not in contact with the piezoelectric wafer and the cable; a filler material, which fills the shaft tube inside the housing; an elastic ring, which is a retaining ring with one open end, with two arms at the opening of one end of the elastic ring rotatably retaining the two ends of the shaft tube, and the other end of the elastic ring straddling one end near the housing, and the other end of the elastic ring not in contact with one end of the housing; and a connecting piece, which is a long strip-shaped piece, with one end of the connecting piece connected to the front end of the handle, and the other end of the connecting piece connected to the other end of the elastic ring.

[0009] Preferably, it also includes: polyester fiber oil-absorbing paper, which is wrapped and placed on the flaw detection contact surface of the probe;

[0010] The limiting plate is a long strip-shaped piece that extends from one end of the housing to the outside of the flaw detection contact surface, and is positioned nearly perpendicular to the flaw detection contact surface.

[0011] Preferably, the elastic ring has a convex or trapezoidal structure.

[0012] Preferably, the starting position is when the plane containing the elastic ring and the flaw detection contact surface is parallel; from the starting position, the counterclockwise rotation angle of the elastic ring relative to the flaw detection contact surface is no greater than 90°, and the clockwise rotation angle of the elastic ring relative to the flaw detection contact surface is no greater than 90°.

[0013] Preferably, it further includes: an auxiliary positioning component, which includes an arc-shaped guide rail disposed on the side wall of the housing, and the arc-shaped guide rail is disposed at the other end near the housing with any through hole as the center, and the arc-shaped guide rail and the elastic ring do not contact each other; a slider slidably disposed on the guide rail; and a connecting rod, one end of which is connected to the slider and the other end of which is connected to the elastic ring.

[0015] Preferably, the filler is a damping material.

[0016] This utility model has at least the following beneficial effects:

[0017] The handheld lever is used to support the joint assembly and probe, thus facilitating the formation of a complete handheld structure and allowing the probe to be easily inserted into the surface of the blade to be inspected in a narrow space.

[0018] In the joint assembly, a pair of through holes and a shaft tube provide a rotatable structural foundation for the elastic ring, facilitating the probe's adaptation to the angle of the surface to be tested and improving the coupling effect. By adding filler, the shaft tube can be effectively fixed inside the housing; on the other hand, it can also isolate the shaft tube from the cable, effectively protecting the cable and providing shielding. The elastic ring is a circular elastic metal wire bent support, which can be easily snapped onto the shaft tube, with a simple structure and easy maintenance. The other end of the elastic ring is connected by tape, rope, or welding, ensuring structural stability.

[0019] The connecting piece is a long strip-shaped piece. On the one hand, it can provide a planar support for the other end of the elastic ring, improving the stability of the mechanical structure and making it easy to use and maintain. On the other hand, it can conveniently bypass obstacles such as guide tubes around the blades to carry out flaw detection.

[0020] The articulated ultrasonic probe device provided by this utility model allows the probe to be delivered to the surface to be inspected via a handheld lever. The articulated assembly can adapt to the position and angle of the surface to be inspected, enabling reliable inspection and effectively improving the coupling effect between the flaw detection contact surface and the surface to be inspected.

[0037] In this solution, the handheld lever is used to support the joint assembly and the probe, thereby facilitating the formation of an overall handheld structure and allowing the probe to be easily inserted into the surface to be tested of the blade 10 located in a narrow space.

[0038] In the joint assembly, a pair of through holes and a shaft tube provide a rotatable structural foundation for the elastic ring, facilitating the probe's adaptation to the angle of the surface to be tested and improving the coupling effect. By adding filler, the shaft tube can be effectively fixed inside the housing; on the other hand, it can also isolate the shaft tube from the cable, effectively protecting the cable and providing shielding. The elastic ring is a circular elastic metal wire bent support, which can be easily snapped onto the shaft tube, with a simple structure and easy maintenance. The other end of the elastic ring is connected by tape, rope, or welding, ensuring structural stability.

[0039] The connecting piece is a long strip-shaped piece. On the one hand, it can provide a planar support for the other end of the elastic ring, improving the stability of the mechanical structure and making it easy to use and maintain. On the other hand, it can conveniently bypass obstacles such as guide tubes around the blades to carry out flaw detection.

[0040] In summary, the articulated ultrasonic probe device provided by this utility model allows the probe to be delivered to the surface to be inspected via a handheld lever. The articulated assembly can adapt to the position and angle of the surface to be inspected, enabling reliable inspection and effectively improving the coupling effect between the flaw detection contact surface and the surface to be inspected.

[0041] like Figure 4 As shown, a preferred embodiment further includes: polyester fiber oil-absorbing paper 204, which is wrapped around the flaw detection contact surface of the probe, effectively improving the coupling effect between the flaw detection contact surface and the surface to be inspected; and a limiting plate 205, which is a long strip-shaped sheet extending from one end of the housing to the outside of the flaw detection contact surface, and is nearly perpendicular to the flaw detection contact surface. The limiting plate is used to abut against the edge of the blade to be inspected, thereby effectively adjusting the angle of the probe, allowing for better coupling between the flaw detection contact surface and the surface to be inspected, and improving the reliability of the inspection results.

[0042] like Figure 3 , 5 As shown, in a preferred embodiment, the elastic ring is a convex or trapezoidal structure.

During the probe's adaptation to the surface to be tested, the probe rotates at a certain angle relative to the elastic ring. The connecting rod fixed to the elastic ring drives the slider to slide a certain distance within the arc-shaped guide rail and then stops. The slider remains in the stopped position to assist in flexibly fixing the probe, allowing it to maintain this angle for a certain period of time after adapting to the surface to be tested, effectively maintaining the coupling effect.
