Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic non-destructive testing technology, and specifically relates to an ultrasonic non-destructive testing probe adjustment device. Background Technology

[0002] Non-destructive testing is an indispensable and effective tool for industrial development. The biggest feature of non-destructive testing is that it can be carried out without damaging the material and structure of the specimen. Ultrasonic testing is more sensitive to cracks, incomplete penetration and lack of fusion defects, and is suitable for detecting whether there are cracks in steel plates and the quality of welds between welded steel plates.

[0003] Chinese Patent Application No. 201920695747.1 discloses an ultrasonic testing device for metal plates, including supporting feet. Supporting feet are fixedly installed at the four corners of the bottom of a supporting platform. A second transverse sliding mechanism is horizontally installed on the top of the supporting platform, connected to a transverse driving device. The transverse driving device is fixedly installed at the end of the supporting platform. A first transverse sliding mechanism is installed on the side of the supporting platform, and a vertical sliding mechanism is slidably sleeved outside the first transverse sliding mechanism. A longitudinal sliding mechanism is slidably sleeved outside the first transverse sliding mechanism. A longitudinal driving device is located below the longitudinal sliding mechanism, and an ultrasonic probe is installed below the longitudinal driving device. The advantages of this invention are: it uses ultrasonic testing, which has strong ultrasonic penetration, allowing for internal testing of metal plates of considerable thickness with accurate defect location; it has low testing cost, high speed, and is harmless to humans and the environment; and it can perform comprehensive testing of steel plates of different widths without blind spots.

[0004] The aforementioned patent uses a vertical sliding mechanism to facilitate the adjustment of the ultrasonic probe height when testing steel plates of different thicknesses. However, in practice, the adjustment is inconvenient, requiring the limit to be released first, then manual adjustment, and finally fixation. Additionally, when the steel plate width is different, the transverse slide rail and transverse sliding sleeve adjust the transverse position of the ultrasonic probe, positioning it at the rear edge of the steel plate. However, this mechanism lacks fixation, resulting in insufficient stability. Furthermore, it is inconvenient to disassemble and repair the ultrasonic probe during use. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4The present invention provides the following technical solution: an ultrasonic non-destructive testing probe adjustment device, including a support platform 1, a transverse drive device 2 installed in the middle above the support platform 1, a platform 3 fixedly connected above the transverse drive device 2, a transverse slide rail 4 fixedly connected to one end of the support platform 1, a transverse sliding sleeve 5 slidably connected to the surface of the transverse slide rail 4, a longitudinal sliding mechanism 7 provided at one end of the transverse sliding sleeve 5, an ultrasonic probe 9 installed below the longitudinal sliding mechanism 7, the transverse sliding sleeve 5 and the longitudinal sliding mechanism 7 connected by an adjustment component 6, and the longitudinal sliding mechanism 7 and the ultrasonic probe 9 connected by a connecting component 8.

[0023] Specifically, the adjustment component 6 includes a lifting seat 61, a lifting trapezoidal screw 62, a throttle 63, an auxiliary rod 64, a square lifting block 65, and a fastening component 66. The lifting seat 61 is fixedly connected to the top of the transverse sliding sleeve 5. The fastening component 66 is installed inside the transverse sliding sleeve 5. The lifting trapezoidal screw 62 is rotatably connected inside the lifting seat 61. One end of the lifting trapezoidal screw 62 passes through the lifting seat 61 and is fixedly connected to the throttle 63. The auxiliary rod 64 is fixedly connected around the surface of the throttle 63. The square lifting block 65 is threadedly connected to the surface of the lifting trapezoidal screw 62. The square lifting block 65 and the lifting seat 61 are in close sliding connection. One end of the square lifting block 65 is fixedly connected to the longitudinal sliding mechanism 7.

[0024] By adopting the above technical solution, by rotating the handle 63, the rotation of the handle 63 will drive the lifting trapezoidal screw 62 inside the lifting seat 61 to rotate. The rotation of the lifting trapezoidal screw 62 will drive the square lifting block 65 with the surface thread to slide inside the lifting seat 61. Thus, the square lifting block 65 drives the longitudinal sliding mechanism 7 fixedly connected on one side to rise and fall, thereby driving the ultrasonic probe 9 installed below the longitudinal sliding mechanism 7 to adjust its height.

[0025] Specifically, the fastening assembly 66 includes a fastening screw 661, a rubber fastening block 662, and a fastening rotating block 663. One end of the transverse sliding sleeve 5 is threadedly connected to the fastening screw 661, one end of the fastening screw 661 is rotatably connected to the rubber fastening block 662, and the other end of the fastening screw 661 is fixedly connected to the fastening rotating block 663.

[0026] By adopting the above technical solution, the transverse slide rail 4 and the transverse sliding sleeve 5 drive the transverse position adjustment of the ultrasonic probe 9, placing the ultrasonic probe 9 at the rear edge of the transverse side of the steel plate. After the movement is completed, the fastening block 663 is rotated, which drives the fastening screw 661 to rotate. The rotation of the fastening screw 661 drives the rubber fastening block 662 to move, thereby fixing the transverse slide rail 4 and the transverse sliding sleeve 5 through the rubber fastening block 662, improving the stability after the movement.

[0027] Specifically, the surface of the fastening block 663 is surrounded and fixedly connected with rubber protrusions 664.

[0028] By adopting the above technical solution, the rubber protrusion 664 serves to prevent slipping.

[0029] In this embodiment, when in use: by rotating the handle 63, the lifting trapezoidal screw 62 inside the lifting seat 61 rotates. The rotation of the lifting trapezoidal screw 62 causes the square lifting block 65, which is threaded on the surface, to slide inside the lifting seat 61. This causes the longitudinal sliding mechanism 7, which is fixedly connected to one side, to rise and fall, thereby adjusting the height of the ultrasonic probe 9 installed below the longitudinal sliding mechanism 7. The transverse slide rail 4 and the transverse sliding sleeve 5 adjust the transverse position of the ultrasonic probe 9, positioning it at the rear edge of the steel plate. After the movement is complete, rotating the fastening block 663 causes the fastening screw 661 to rotate. The rotation of the fastening screw 661 causes the rubber fastening block 662 to move, thus fixing the transverse slide rail 4 and the transverse sliding sleeve 5, improving the stability after movement. This allows the height of the ultrasonic probe 9 to be easily adjusted according to the thickness of the steel plate being tested, improving ease of use.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that, specifically, the connecting component 8 includes a clamping seat 81, a bidirectional trapezoidal lead screw 82, a clamping rotating block 83, an anti-slip sleeve 84, a square slider 85, a clamping plate 86, and a rubber pad 87. The clamping seat 81 is installed below the longitudinal sliding mechanism 7. The bidirectional trapezoidal lead screw 82 is rotatably connected inside the clamping seat 81. One end of the bidirectional trapezoidal lead screw 82 passes through the clamping seat 81 and is fixedly connected to the clamping rotating block 83. The anti-slip sleeve 84 is fixedly connected to the surface of the clamping rotating block 83. The surface of the bidirectional trapezoidal lead screw 82 is symmetrically and threadedly connected to the square slider 85. The square slider 85 and the clamping seat 81 are in close sliding connection. The clamping plate 86 is fixedly connected below the square slider 85. The rubber pad 87 is fixedly connected to one side of the clamping plate 86. One side of the rubber pad 87 is in close contact with the ultrasonic probe 9.

[0032] By adopting the above technical solution, rotating the clamping block 83 causes the bidirectional trapezoidal lead screw 82 to rotate, which in turn moves the square slider 85. The square slider 85 then moves the clamping plate 86 fixedly connected below, thus cooperating with the rubber pad 87 to clamp and fix the ultrasonic probe 9. After clamping, due to the self-locking characteristic of the trapezoidal lead screw, the two sides of the trapezoidal teeth are inclined. When the lead screw is subjected to a reverse force, the inclined surfaces generate a frictional force that prevents it from rotating. This frictional force increases with the increase of the reverse force, allowing the lead screw to remain stationary when subjected to a sufficiently large reverse force, achieving self-locking and maintaining clamping stability.

[0033] Specifically, mounting blocks 88 are fixedly connected to both sides of the clamping base 81, and mounting screws 89 are inserted into the middle of the mounting blocks 88, and the mounting screws 89 are threadedly connected to one end of the longitudinal sliding mechanism 7.

[0034] By adopting the above technical solution, the mounting block 88 and the mounting screw 89 cooperate to facilitate the installation and fixation of the clamping seat 81, thereby installing and fixing the connecting component 8.

[0035] In this embodiment, during use: rotating the clamping block 83 causes the bidirectional trapezoidal lead screw 82 to rotate, which in turn moves the square slider 85. The square slider 85 then moves the clamping plate 86 fixedly connected below, thus engaging with the rubber pad 87 to clamp and fix the ultrasonic probe 9. After clamping, due to the self-locking characteristic of the trapezoidal lead screw, the two sides of the trapezoidal teeth are inclined. When the lead screw is subjected to a reverse force, the inclined surfaces generate a frictional force that prevents it from rotating. This frictional force increases with the increase of the reverse force, allowing the lead screw to remain stationary under a sufficiently large reverse force, achieving self-locking and maintaining clamping stability. This allows the ultrasonic probe 9 to be easily disassembled and repaired during use.

[0036] The structure and operating principle of the support platform 1, transverse drive device 2, placement platform 3, transverse slide rail 4, transverse sliding sleeve 5, longitudinal sliding mechanism 7, and ultrasonic probe 9 in this utility model have been disclosed in a metal plate ultrasonic testing device disclosed in Chinese patent application number 201920695747.1. Its working principle is as follows: the steel plate to be tested is placed on the upper surface of the placement platform 3, and one side of the steel plate is pressed against the "L"-shaped raised part of the placement platform 3. Pressing the reset switch connects the circuit of the stepper motor, and the stepper motor drives the lead screw to rotate. The lead screw and lead screw nut interact to move the placement platform 3 laterally to the foremost position. At this time, the drive motor drives the drive gear. As the wheel rotates, the drive gear moves longitudinally to the leftmost end relative to the longitudinal slide bar. Pull or push the push-pull handle by hand to position the ultrasonic probe 9 at the rear edge of the steel plate to be inspected laterally. Press the start button to start the device. During operation, the drive motor drives the drive gear to rotate, and the drive gear drives the longitudinal slide sleeve to move left and right outside the longitudinal slide bar. When the longitudinal slide sleeve moves left or right once, the stepper motor rotates once, driving the stage 3 to move longitudinally backward. In this way, the ultrasonic probe 9 moves back and forth with the longitudinal slide sleeve, and the steel plate to be inspected moves backward along the direction of the second transverse rail with the stage 3 until the steel plate to be inspected is completely inspected.

[0037] The working principle and usage process of this utility model are as follows: In use, a steel plate is placed on the platform 3. The height of the ultrasonic probe 9 is adjusted using the adjusting component 6 according to the thickness of the steel plate. After adjustment, the ultrasonic probe 9 is positioned at the rear edge of the steel plate by sliding the transverse sliding sleeve 5 on the transverse slide rail 4. After movement, it is secured by the fastening component 66. Then, the ultrasonic probe 9 can be driven for detection through the cooperation of the transverse drive device 2 and the longitudinal sliding mechanism 7. When the ultrasonic probe 9 needs to be removed for inspection and maintenance, it can be quickly disassembled and reassembled through the connecting component 8. When using the adjusting component 6, rotating the handle 63 will cause the lifting trapezoidal screw 62 inside the lifting seat 61 to rotate. The rotation of the lifting trapezoidal screw 62 will cause the square lifting block 65, which is threaded on the surface, to slide inside the lifting seat 61. This, in turn, drives the longitudinal sliding mechanism 7, which is fixedly connected to one side, to rise and fall, thereby adjusting the height of the ultrasonic probe 9 installed below the longitudinal sliding mechanism 7. The transverse slide rail 4 and the transverse sliding mechanism 5 are then used to adjust the height of the ultrasonic probe 9. The sliding sleeve 5 adjusts the lateral position of the ultrasonic probe 9, positioning it at the rear edge of the steel plate. After movement, the fastening block 663 is rotated, causing the fastening screw 661 to rotate. The rotation of the screw 661 moves the rubber fastening block 662, thus fixing the transverse slide rail 4 and the sliding sleeve 5 together, improving stability after movement. This allows the height of the ultrasonic probe 9 to be easily adjusted according to the thickness of the steel plate being tested, improving usability. For ease of use, when the connecting component 8 is in use, rotating the clamping rotating block 83 causes the bidirectional trapezoidal lead screw 82 to rotate, which in turn causes the square slider 85 to move. The square slider 85 then moves the clamping plate 86 fixedly connected below, thus clamping and fixing the ultrasonic probe 9 in conjunction with the rubber pad 87. After clamping, due to the self-locking characteristic of the trapezoidal lead screw, the two sides of the trapezoidal teeth are inclined. When the lead screw is subjected to a reverse force, the inclined surfaces generate a frictional force that prevents it from rotating. This frictional force increases with the increase of the reverse force, allowing the lead screw to remain stationary when subjected to a sufficiently large reverse force, achieving self-locking and maintaining clamping stability. This allows the ultrasonic probe 9 to be easily disassembled and repaired during use.
