Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and more specifically, to a nondestructive testing flaw detection scanning device. Background Technology

[0002] Non-destructive testing (NDT) refers to the technology of detecting defects, chemical and physical parameters of materials, parts and equipment without damaging or affecting the performance of the tested object or its internal structure. This is achieved by using principles and technologies such as X-rays, ultrasound, infrared, and electromagnetics, combined with instruments.

[0003] Chinese utility model patent CN220019486U discloses a probe clamping and scanning device for ultrasonic non-destructive testing, including two bases. A pair of support seats are provided on the outer wall of each base, and a motor is detachably mounted on one side of the inner bottom wall of each base. A lead screw is provided at the output end of the motor, and the other end of the lead screw is rotatably connected to the inner wall of the base via a bearing. This technical solution uses components such as a motor, lead screw, hydraulic cylinder, and pneumatic cylinder to achieve the reciprocating motion of the probe, replacing manual drive with mechanization. This enables omnidirectional scanning of the probe on the workpiece, improving the degree of automation and enhancing the practicality and efficiency of the inspection. However, while this technical solution can achieve moving scanning of the workpiece, its scanning method is limited, only capable of scanning and inspecting planar objects or cylindrical objects with smooth, flat outer edges. It cannot meet the inspection needs of circumferential objects with curved or inclined surfaces, thus having certain limitations in use. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a non-destructive testing scanning device, which enables the probe to rotate around a circumferential object by adding a rotating structure and a probe tilt adjustment structure, and makes the probe perpendicular to the test position on the outer periphery of the object, thereby meeting the flaw detection scanning needs of objects of different shapes and effectively improving the practicality and applicability of the device.

[0005] To achieve the above objectives, this utility model provides a non-destructive testing scanning device, mounted on a base, comprising: The longitudinal moving structure includes two horizontally parallel and symmetrically mounted sliding tables on the upper surface of the base along the length direction of the base, and a gantry frame mounted on the two sliding tables, the gantry frame being adapted to move along the sliding tables; The detection structure includes a planar flaw detection component vertically arranged inside the gantry for detecting the top surface of an object, and an outer peripheral flaw detection component horizontally arranged inside the gantry for detecting the circumferential surface of an object. The rotating structure includes a rotary motor installed in the middle of the top surface of the gantry frame and an electric slide rail installed at the output end of the rotary motor and located below the horizontal section of the gantry frame. The rotary motor is used to drive the electric slide rail to rotate. A lifting structure is fixedly installed on the slider of the electric slide rail, and the electric slide rail is used to drive the lifting structure to move horizontally. A lateral moving structure is horizontally installed on one side of the lifting structure in the width direction and located below the electric slide rail. The lateral moving structure is used to adjust the displacement of the peripheral flaw detection component in the horizontal direction. A tilt adjustment structure is slidably installed inside the lifting structure. The lifting structure is used to drive the tilt adjustment structure to move up and down. The tilt adjustment structure is used to adjust the tilt angle of the planar flaw detection component. When the lifting structure is located on one side of the width direction of the object to be inspected, the synchronous operation of the longitudinal moving structure and the lateral moving structure can enable the planar flaw detection component to inspect any position on the top surface of the object; when the object to be inspected is circumferential, the synchronous operation of the lifting structure, the tilting adjustment structure and the rotating structure can enable the peripheral flaw detection component to inspect any position on the outer periphery of the object, and during the inspection process, the planar flaw detection component is made perpendicular to the part of the object currently being inspected by the planar flaw detection component.

[0006] Furthermore, the lifting structure includes a sliding seat installed at the bottom of the electric slide rail, a lifting slider horizontally slidably installed in the sliding seat, and a lifting adjustment component installed in the sliding seat for driving the lifting slider to move up and down.

[0007] Furthermore, the lifting adjustment assembly includes a lifting motor installed inside the sliding seat and a threaded rod installed at the output end of the lifting motor and threadedly connected to the lifting slider.

[0008] Furthermore, the lifting slider is U-shaped, and the tilt adjustment structure is installed inside the lifting slider.

[0009] Furthermore, the tilt adjustment structure includes a first mounting base rotatably mounted inside the lifting slider and a rotation adjustment assembly mounted on the lifting slider and used to drive the first mounting base to rotate, and the peripheral flaw detection component is installed inside the first mounting base.

[0010] Furthermore, the rotation adjustment assembly includes a first gear installed in the first mounting base, a drive component installed on one side of the lifting slider in the width direction, and a second gear installed at the output end of the drive component and meshing with the first gear. The axis of the first gear is coaxial with the rotation axis of the first mounting base.

[0011] Furthermore, the lateral movement structure includes an electric telescopic rod horizontally mounted on the sliding seat and located directly below the electric slide rail, and a second mounting base mounted on the output end of the electric telescopic rod. The electric telescopic rod is arranged parallel to the electric slide rail, and the planar flaw detection component is installed in the second mounting base.

[0012] Furthermore, a limiting ring in an annular arrangement is fixedly connected to the bottom of the horizontal section of the gantry frame, and an arc-shaped groove adapted to slide on the top of the electric slide rail.

[0013] Furthermore, the non-destructive testing flaw detection scanning device also includes: The lifting structure includes a support plate for supporting and mounting the object to be measured, and several hydraulic rods vertically inserted into the bottom of the base for adjusting the height of the support plate.

[0014] Compared with the prior art, this utility model has the following advantages and effects: 1. The non-destructive testing (NDT) scanning device of this utility model utilizes an electric slide rail in its rotating structure to bring the planar flaw detection component close to the outer wall of the object under test. A lifting structure allows the planar flaw detection component to detect objects at different heights. Combined with the operation of the rotary motor in the rotating structure, the planar flaw detection component rotates around the outer wall of the object under test, thus achieving comprehensive detection of circumferential objects. Furthermore, during the detection process, the tilt angle of the planar flaw detection component can be adjusted to make it perpendicular to the corresponding position on the object, further improving the detection effect. In addition, by operating only the moving slide and the lateral movement structure, the device can also achieve comprehensive detection of the top surface of the object. This allows the flaw detection scanning device to perform scanning detection on objects of different shapes using two different scanning methods, effectively improving the applicability of the device.

[0015] 2. The non-destructive testing scanning device of this utility model adds a lifting structure so that the object to be tested can move closer to the second detection component, thereby conveniently adapting to the detection needs of the top surface of objects of different heights.

[0020] Please see Figure 1-3 As shown, this utility model embodiment provides a non-destructive testing scanning device, which is installed on a base 1 and includes a longitudinal moving structure 2, a detection structure 6, a rotating structure 3, a lateral moving structure 7, a tilting adjustment structure 5, and a lifting structure 4.

[0021] The longitudinal moving structure 2 includes a sliding table 21 and a gantry 22. The two sliding tables 21 are horizontally parallel and symmetrically installed on the upper surface of the base 1 along the length direction of the base 1. The gantry 22 is installed on the two sliding tables 21 and is adapted to move along the sliding tables 21 so as to adjust the position of the gantry 22 in the length direction of the base 1 using the sliding tables 21.

[0022] The detection structure 6 includes a planar flaw detection component 62 and a peripheral flaw detection component 61. The planar flaw detection component 62 is vertically arranged inside the gantry 22 and is used to detect the top surface of the object. The peripheral flaw detection component 61 is horizontally arranged inside the gantry 22 and is used to detect the peripheral surface of the object. The planar flaw detection component 62 and the peripheral flaw detection component 61 are used to detect planar objects and circumferential objects respectively.

[0023] The rotating structure 3 includes a rotary motor 31 and an electric slide rail 32. The rotary motor 31 is installed in the middle of the top surface of the gantry 22, and the electric slide rail 32 is installed at the output end of the rotary motor 31 and located below the horizontal section of the gantry 22, so that the rotation of the rotary motor 31 can drive the electric slide rail 32 to rotate around the center point of the gantry 22.

[0024] The lifting structure 4 is fixedly installed on the slider of the electric slide rail 32, which is used to drive the lifting structure 4 to move horizontally.

[0025] The lateral moving structure 7 is horizontally installed on one side of the lifting structure 4 in the width direction and located below the electric slide rail 32. The lateral moving structure 7 is used to adjust the displacement of the peripheral flaw detection component 61 in the horizontal direction.

[0026] The tilt adjustment structure 5 is slidably installed inside the lifting structure 4. The lifting structure 4 is used to drive the tilt adjustment structure 5 to move up and down. The tilt adjustment structure 5 is used to adjust the tilt angle of the planar flaw detection component 62.

[0027] When the lifting structure 4 is located on one side of the width direction of the object to be inspected, the synchronous operation of the longitudinal moving structure 2 and the lateral moving structure 7 can enable the planar flaw detection component 62 to inspect any position on the top surface of the object; when the object to be inspected is circumferential, the synchronous operation of the lifting structure 4, the tilt adjustment structure 5 and the rotation structure 3 can enable the peripheral flaw detection component 61 to inspect any position on the outer periphery of the object, and during the inspection process, the planar flaw detection component 62 is perpendicular to the part of the planar flaw detection component 62 currently being inspected on the object.

[0028] Please see Figure 1-2As shown, the lifting structure 4 includes a sliding seat 41, a lifting slider 44, and a lifting adjustment assembly. The sliding seat 41 is installed at the bottom of the electric slide rail 32. The lifting slider 44 is horizontally slidably installed inside the sliding seat 41. The lifting adjustment assembly is installed inside the sliding seat 41 to drive the lifting slider 44 to move up and down. This allows the peripheral flaw detection component 61 to detect objects at different heights by adjusting the lifting slider 44 when the peripheral flaw detection component 61 is inspecting circumferential objects.

[0029] Please see Figure 1-3 As shown, the lifting adjustment assembly includes a lifting motor 42 and a threaded rod 43. The lifting motor 42 is installed inside the sliding seat 41, and the threaded rod 43 is installed at the output end of the lifting motor 42. The threaded rod 43 is threadedly connected to the lifting slider 44, which facilitates the lifting slider 44 to move up and down within the sliding seat 41 as the threaded rod 43 rotates.

[0030] Please see Figure 2-3 As shown, the lifting slider 44 is U-shaped, and the tilt adjustment structure 5 is installed inside the lifting slider 44.

[0031] Please see Figure 2-3 As shown, the tilt adjustment structure 5 includes a first mounting base 51 and a rotation adjustment assembly. The first mounting base 51 is rotatably mounted inside the lifting slider 44. The rotation adjustment assembly is mounted on the lifting slider 44 and is used to drive the first mounting base 51 to rotate. The peripheral flaw detection component 61 is mounted inside the first mounting base 51, so that the tilt angle of the peripheral flaw detection component 61 can be adjusted by rotating the first mounting base 51, so that when the peripheral of the object to be tested is arc-shaped or inclined, the peripheral flaw detection component 61 can fit the corresponding position of the object to be tested.

[0032] Please see Figure 2-3 As shown, the rotation adjustment assembly includes a first gear 52, a drive member 53, and a second gear 54. The first gear 52 is installed inside the first mounting base 51, the drive member 53 is installed on one side of the lifting slider 44 in the width direction, and the second gear 54 is installed at the output end of the drive member 53 and meshes with the first gear 52. The axis of the first gear 52 is coaxial with the rotation axis of the first mounting base 51. This allows the second gear 54 to rotate the first mounting base 51 under the action of the drive member 53 by meshing with the first gear 52, thereby achieving the tilt angle adjustment function.

[0033] As a preferred embodiment of the above scheme, the driving component 53 is a servo stepper motor, which facilitates precise adjustment of the rotation angle of the first mounting base 51 by controlling the operation of the servo stepper motor.

[0034] Please see Figure 1-2As shown, the lateral movement structure 7 includes an electric telescopic rod 71 and a second mounting base 72. The electric telescopic rod 71 is horizontally mounted on the sliding seat 41 and located directly below the electric slide rail 32. The second mounting base 72 is mounted on the output end of the electric telescopic rod 71. The electric telescopic rod 71 is arranged parallel to the electric slide rail 32. The planar flaw detection component 62 is installed inside the second mounting base 72. This allows for easy adjustment of the lateral position of the second mounting base 72 and the planar flaw detection component 62 by operating the electric telescopic rod 71, enabling the planar flaw detection component 62 to correspond to any position in the width direction of the object to be inspected.

[0035] Please see Figure 1-2 As shown, a ring-shaped limiting ring 221 is fixedly connected to the bottom of the horizontal section of the gantry frame 22, and an arc-shaped groove 321 is provided on the top of the electric slide rail 32 to slide and adapt to the limiting ring 221; this facilitates the use of the cooperation between the limiting ring 221 and the arc-shaped groove 321 to improve the stability of the electric slide rail 32 during rotation.

[0036] Please see Figure 1-2 As shown, the non-destructive testing scanning device also includes a support structure 8, which includes a support plate 82 for supporting and installing the object to be tested, and several hydraulic rods 81 vertically inserted and installed at the bottom of the base 1 for adjusting the height of the support plate 82; so that the operation of the hydraulic rods 81 can drive the support plate 82 to move up and down, thereby facilitating the top surface of the object to be tested to approach the planar flaw detection component 62.

[0037] The working process of the non-destructive testing scanning device described above is as follows: When the non-destructive testing scanning device inspects a planar object, it first needs to operate the rotating structure 3 to make the electric slide rail 32 parallel to the horizontal section of the gantry 22, and operate the electric slide rail 32 to make the lifting structure 4 move away from the center of the gantry 22. Then, the object to be tested can be installed on the tray 82, and the tray 82 can be moved towards the planar flaw detection component 62 by operating the hydraulic rod 81. During testing, the lateral moving structure 7 can be operated to adjust the position of the second mounting base 72 so that the planar flaw detection component 62 in the second mounting base 72 corresponds to the position of the part to be tested in the width direction of the object to be tested. At the same time, the moving slide 21 can also drive the gantry 22 to move so that the planar flaw detection component 62 in the second mounting base 72 corresponds to the position of the part to be tested in the length direction of the object to be tested, thereby realizing the detection of any position on the top surface of the object to be tested. When the non-destructive testing scanning device is used to inspect a circumferential object, the hydraulic rod 81 is first operated to adjust the position of the support plate 82 so that the support plate 82 is located below the sliding seat 41 in the lifting structure 4. Then, the object to be tested is installed on the support plate 82. After that, the electric slide rail 32 can be operated to make the sliding seat 41 drive the first mounting seat 51 and the peripheral flaw detection component 61 to move closer to the periphery of the object to be tested. The operation of the lifting structure 4 can make the lifting slider 44 drive the first mounting seat 51 and the peripheral flaw detection component 61 to move up and down, so as to facilitate the inspection of the object at different height positions. The rotation structure 3 allows the peripheral flaw detection component 61 to rotate around the object to be tested, thus facilitating the detection of different positions on the circumference of the object. During the detection process, the tilt adjustment structure 5 can also be used to adjust the tilt angle of the first mounting base 51 and the peripheral flaw detection component 61 so that the peripheral flaw detection component 61 is perpendicular to the part of the object to be tested.

[0038] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
