[0027] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0030] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] The present invention provides a magnetized array eddy current testing device, comprising a base 1, a test box 2, a test probe 3, and an eddy current flaw detector 4. The test box 2 is slidably mounted on the base 1 and is movable along the X-direction. Multiple test probes 3 are arrayed within the test box 2 and are movable along the Y-direction within the test box 2. The eddy current flaw detector 4 is fixedly mounted on the base 1 and is electrically connected to the test probes 3. In this application, the X-direction and the Y-direction are perpendicular.

[0032] During operation, the entire device is first placed below the workpiece to be inspected. The multiple detection probes 3 are then driven to move, inspecting a designated area of the workpiece as they move. The corresponding inspection information is then transmitted to the eddy current flaw detector 4 for analysis. It should be noted that the eddy current flaw detector 41 and the multiple detection probes 33 utilize existing technologies, and their specific structures and principles are not further described here.

[0033] In this embodiment, by sliding the detection box 2 on the base 1 and then sliding the detection probe 3 on the detection box 2, the detection probe 3 can be moved along the X direction and the Y direction on the base 1, thereby completing the effective and rapid detection of large workpieces to be detected, with high detection efficiency and good detection effect.

[0034] In a preferred embodiment, a guide groove 11 is provided on the base 1 along the X direction, and a slider 21 is provided protruding from the bottom of the detection box 2, and the slider 21 is slidably installed in the guide groove 11. The guide groove 11 and the slider 21 can further increase the stability of the detection box 2 during movement, thereby improving the accuracy of detection by the detection probe 3. A plurality of guide grooves 11 are evenly spaced on the base 1, and the plurality of guide grooves 11 are evenly spaced along the X direction. This solution has a simple structure and a reasonable design. The plurality of guide grooves 11 and the plurality of sliders 21 can further increase the stability of the movement of the detection box 2 and further improve the accuracy of detection by the detection probe 3. Preferably, in this embodiment, the number of guide grooves 11 is two, and the two guide grooves 11 are respectively located at the two ends of the detection box 22.

[0035] Furthermore, an X-drive cylinder 12 is fixedly mounted on the base 1. Its piston rod is connected to the detection box 2, and the X-drive cylinder 12 can drive the detection box 2 to move in the X direction. This allows for horizontal movement of the detection box 2, allowing for inspection of a larger area of the workpiece, improving inspection efficiency and reducing labor intensity. The X-drive cylinder 12 extends and retracts, driving the movement of the detection box 2.

[0036] Each detection probe 3 corresponds to a detection rod 31, and the detection probe 3 is mounted on the first end of the detection rod 31. A Y-drive cylinder 22 is provided within the detection box 2. A connecting rod 23 is provided on the piston rod of the Y-drive cylinder 22. The second end of the detection rod 31 is mounted on the connecting rod 23. The Y-drive cylinder 22 can drive the detection probe 3 to move along the Y direction. The linkage between the Y-drive cylinder 22 and the X-drive cylinder 12 enables the detection probe 3 to move freely within the plane, thereby increasing the detection range. Furthermore, the participation of the Y-drive cylinder 22 and the X-drive cylinder 12 in driving eliminates manual intervention, greatly improving detection efficiency.

[0037] The detection box 2 is provided with strip-shaped openings 24 along the Y direction, corresponding one to each of the detection rods 31. The detection rods 31 can extend out of the detection box 2 through the strip-shaped openings 24 and can move along the strip-shaped openings 24. Multiple detection probes 3 are respectively installed in the multiple strip-shaped openings, and each detection probe 3 is closely aligned with the corresponding strip-shaped opening. The rational design ensures the stability of the detection probes 3 during movement.

[0038] Furthermore, the bottom of the Y-drive cylinder 22 is slidably connected to the side wall of the detection box 2, and the Y-drive cylinder 22 can move in the Z direction. A Z-drive cylinder 25 is provided in the detection box 2, and the piston rod of the Z-drive cylinder 25 is connected to the Y-drive cylinder 22. The Z-drive cylinder 25 can drive the Y-drive cylinder 22 to move in the Z direction. In this embodiment, by driving the Y-drive cylinder 22 to move in the Z direction, the detection probe 3 can be driven to move in the Z direction, where the Z direction is the vertical direction. That is, during use, the distance between the detection probe 3 and the workpiece to be detected can be adjusted. When the diameter of the workpiece to be detected changes, different parts of the workpiece to be detected can also be detected by changing the height of the detection probe 3 in the vertical direction.

[0039] Finally, a roller assembly (not shown) is provided at the bottom of the base 1. The roller assembly is provided on the base 1 to facilitate the movement of the base 1.
