Description

Technical Field

[0001] The invention belongs to the field of non-destructive testing of materials, and in particular relates to a water jet ultrasonic C-scanning testing system. Background Art

[0002] The water jet ultrasonic C-scan equipment is an advanced non-destructive testing tool, widely used in the detection and quality control of the internal structure of materials. Its core working principle is based on ultrasonic technology:

[0003] Ultrasonic transmission and reception: The device uses a transmitting transducer to emit high-frequency ultrasonic signals into the material being inspected. These signals propagate within the material and are reflected when they encounter different media (such as defects or interfaces between layers). The receiving transducer captures these reflected waves and converts them into electrical signals.

[0004] The function of the water spray system: The water spray system forms a liquid coupling layer between the ultrasonic detector and the material being tested. Usually water or a similar liquid is used. This liquid medium can effectively reduce signal attenuation and improve signal transmission efficiency, thereby obtaining clearer detection results.

[0005] C-scan imaging technology: C-scan is a two-dimensional imaging technique that collects data point by point by scanning an ultrasonic probe along the surface of a material. A computer system processes this data and generates cross-sectional images of the material's interior. These images reveal structural details within the material, enabling inspectors to identify potential defects such as cracks, pores, or delamination.

[0006] Applications: This device plays an important role in multiple industries. For example, in the aerospace sector, it is used to inspect the structural integrity of aircraft fuselages and wing panels; in the automotive industry, it can be used to inspect the weld quality and internal structure of automotive components; in the manufacturing industry, it is mainly used for quality control and to detect defects in composite materials; and in the construction industry, it is used to detect potential problems in concrete and steel structures.

[0007] Equipment Advantages: Waterjet ultrasonic C-scan equipment offers nondestructive testing capabilities, without damaging materials. Furthermore, it provides high-resolution inspection results, accurately identifying tiny defects and generating real-time images for rapid analysis and decision-making.

[0008] In summary, water jet ultrasonic C-scan equipment provides an efficient and accurate solution for the detection of internal structure of materials through advanced ultrasonic technology and water jet system, playing an important role in multiple industrial fields.

[0009] Currently, most water jet penetrating scanning inspection equipment utilizes a gantry-style structure. This prolonged reciprocating motion can affect the connections between components, leading to difficult-to-correct misalignment of the ultrasonic probe at the end, thus affecting the equipment's inspection accuracy. Furthermore, water jet penetrating scanning equipment is primarily used to inspect plate-type parts, which vary in size and shape, and most often have a certain degree of curvature. The flatness of the part itself can also affect the accuracy of the equipment's inspection results.

[0010] On the other hand, in the application field of water jet penetration scanning detection equipment, its detection function has not yet been expanded and modified, making its detection application scenario relatively single and only applicable to thinner flat-plate objects. It cannot cope with the parts to be tested that require water immersion ultrasonic testing technology.

[0011] In the face of the problems that current water jet penetration scanning detection equipment has multiple sources of detection errors and very limited detection capabilities, it is urgent to propose a water jet ultrasonic C-scan detection system. Utility Model Content

[0033] To fully describe the technical content, structural features, objectives and effects of the present invention, the following is a detailed description with reference to the accompanying drawings.

[0034] The utility model provides a water spray ultrasonic C-scan detection system, such as Figure 1-5 As shown, it includes an experimental shell, an ultrasonic test piece, a fixing device and a connecting device; the ultrasonic test piece, the fixing device and the connecting device are all arranged inside the experimental shell; the fixing device includes an upper adapter plate 3, a lower adapter plate 5 and a knob worm structure 4, the upper adapter plate 3 is arranged above the lower adapter plate 5, and the upper adapter plate 3 is connected to the lower adapter plate 5 through the knob worm structure 4, the upper part of the upper adapter plate 3 is connected to the scanning equipment of the ultrasonic test piece, and the lower part of the lower adapter plate 5 is connected to the bottom plate.

[0037] The immersion probe adapter structure includes a threaded joint, an extension rod 31, a 90° steering joint 32 and a probe fixing base 33.

[0038] The experimental shell is a rectangular stainless steel frame structure, which has a water collection tank, a steel structure mesh bottom plane, four side corner steel structure columns, a water retaining curtain, a top guide rail 1 and a gantry-type double-arm mechanical axis from bottom to top. The water collection tank is parallel to the steel structure mesh bottom plane, the four side corner steel structure columns are perpendicular to the steel structure mesh bottom plane and are fixed at the four corners respectively, the top guide rail 1 and the four side corner steel structure columns are perpendicular to each other and fixed with bolts, the water retaining curtain is fixed under the fixed beam of the top guide rail 1, and the gantry-type double-arm mechanical axis is fixed across the top guide rail 1.

[0039] The knob worm structure 4 and the experimental housing are both known structures, and their structures are not limited in the embodiment. Any type of related structure can enable the implementation of this embodiment.

[0040] The guide rail 1 is provided with a plurality of positioning holes.

[0041] A limit button 14 is provided on each of the first and second sliders. A through hole is provided on each of the first and second sliders. An internal thread structure is provided inside the through hole. An external thread structure matching the internal thread structure of the through hole is provided on the side wall of the limit button 14.

[0042] The universal joint seat 9 includes a first clamping plate, a second clamping plate and a first bolt. The first clamping plate and the second clamping plate are symmetrically arranged, and a slot for the fixing rod 11 to pass through is opened between the first clamping plate and the second clamping plate.

[0044] like Figure 1 As shown, the guide rail 1 is fixed to the water jet ultrasonic C scanning equipment platform with bolts, and multiple sliders 2 slide into the guide rail 1 from one side of the guide rail to form a moving pair with only one degree of freedom. The support seat 12 is fixed to the threaded hole on the upper end of the slider through its bottom thread. The limit button 14 contacts the guide rail 1 through the side thread of the slider. Tightening the limit button 14 can limit the relative movement of the slider 2 and the guide rail 1.

[0045] like Figure 2 As shown, the upper adapter plate 3 is fixedly connected to the knob-worm gear structure 4 and the Z-axis end of the water jet ultrasonic C-scan device via bolts. The lower adapter plate 5 is fixedly connected to the knob-worm gear structure 4 and the AB-axis system of the water jet ultrasonic C-scan device via bolts. Rotating the adjustment knob 21 generates a single degree of freedom motion along the X-axis to adjust the relative position of the AB-axis system and the Z-axis end of the water jet ultrasonic C-scan device. Because the worm gear mechanism is a motion-reducing mechanism, precise alignment of the bilateral probes can be achieved by slightly rotating the adjustment knob 21, thereby eliminating the problem of reduced detection accuracy of the water jet ultrasonic C-scan device caused by accumulated motion errors.

[0046] like Figure 3 As shown, the top thread of the extension rod 31 is screwed into the water bag of the AB axis system of the water jet ultrasonic C-scanning device. It is then connected to another extension rod 31 via a 90° turning joint. The probe holder 33 at the end of the extension rod 31 is also threadedly connected to it, and the entire system is directly fixed without relative movement. This adapter device can be used to connect and fix the corresponding immersion ultrasonic probe. The probe holder 33 has a signal transmission line, thereby expanding the ultrasonic testing function. This functional expansion can be performed on both sides of the AB axis system, allowing for simultaneous immersion ultrasonic testing of two identical test parts. This expands the detection function while doubling the detection efficiency.

[0047] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
