Description

Technical Field

[0001] This invention relates to the field of ultrasonic testing equipment technology, specifically to an ultrasonic sensor specifically designed for non-destructive testing. Background Technology

[0002] Ultrasonic probes contain piezoelectric crystals. When excited by voltage, the piezoelectric crystals generate ultrasonic signals and emit them into the object being tested. The piezoelectric crystals inside the probes can also convert the received ultrasonic signals into electrical signals and transmit them to processing equipment for analysis. However, in order to cope with non-destructive testing of different workpieces, it is usually necessary to flexibly replace different models of probes for testing and to adjust the ultrasonic incident angle of different probes. Existing ultrasonic sensors are inconvenient to replace and adjust.

[0003] For example, an ultrasonic sensor for non-destructive testing of carbon steel spot weld quality, as disclosed in announcement number CN219512163U, includes a sensor body. A switch is installed on one side of the sensor body, and an easy-pull handle is fixedly connected to the surface of the sensor body for easy handling by workers. A fixing plate is installed on the upper surface of the sensor body, and a probe sleeve is fixedly connected to the lower surface of the sensor body. A sensor probe is installed inside the probe sleeve and is used to emit and receive ultrasonic waves. Fixing structures are provided on both sides of the fixing plate. The fixing structure includes two sets of limiting blocks, and a rotating shaft is rotatably connected between the two limiting blocks. A locking block is fixedly connected to the arc surface of the rotating shaft. This device solves the problem of poor detection effect due to lack of fixation when using ultrasonic sensors for carbon steel spot weld quality testing. However, the device is not convenient for easy replacement of ultrasonic sensors and adjustment of the corresponding detection angle, which reduces the flexibility of use and the accuracy of non-destructive testing, and has certain defects.

[0004] Therefore, a dedicated ultrasonic sensor for nondestructive testing is proposed to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasonic sensor specifically for non-destructive testing, so as to solve the problem that the device is not convenient to replace the ultrasonic sensor and adjust the corresponding detection angle, which reduces the flexibility of the device and the accuracy of the non-destructive testing effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic sensor for non-destructive testing, comprising a substrate, a servo driver, an ultrasonic probe, and a display device fixedly mounted on one side of the substrate, wherein a water tank is fixedly mounted on the top of the substrate;

[0007] Also includes:

[0008] The mounting structure is located on one side of the servo driver three. The mounting structure includes a mounting frame, and a rotating structure is provided inside the mounting frame.

[0009] The mounting frame is fixedly connected to the output end of the servo driver three. A wiring part is fixedly installed on the upper part of one side of the servo driver three. A mounting plate is rotatably installed on one side of the mounting frame. A connecting rod is fixedly installed on the top of the ultrasonic probe.

The sliding groove is arranged in an array, and there are no fewer than three sliding grooves.

[0013] By adopting the above technical solution, the connecting rod will also drive the locking pin to lock into the slot, thereby positioning the mounting sleeve.

[0014] Preferably, the locking pin is located on the inner bottom surface of the sliding groove, the mounting sleeve is slidably connected to the mounting plate, the locking groove is opened in an array, the number of the locking groove is the same as the number of locking pins, and the positions correspond one-to-one.

[0015] By adopting the above technical solution, rotating the top block will cause the arc-shaped block to move the connecting rod. The connecting rod slides inside the slide groove, and the connecting rod drives the locking pin to lock into the slot.

[0016] Preferably, the connecting rod is located inside the slide groove and is slidably connected to the slide groove, the arc-shaped block is located outside the mounting plate, and the inner side of the arc-shaped block is in contact with the connecting rod.

[0019] By adopting the above technical solution, the outer ring is inserted into the positioning ring, and the outer ring drives the vertical plate to press down, so that the horizontal bar can be inserted into the slot of the positioning ring.

[0020] Preferably, a spring is fixedly connected to one side of the vertical plate, and the end of the spring away from the vertical plate is fixedly connected to the horizontal bar. A slot is provided inside the positioning ring, and the horizontal bar is engaged with the slot.

[0021] By adopting the above technical solution, pressing down on the positioning sleeve causes the bottom end of the positioning sleeve to block the limiting block, thereby improving the installation firmness of the outer ring and the positioning ring.

[0022] Preferably, a limiting block is fixedly connected to one side of the top of the crossbar, the limiting block is located inside the outer ring body, and the number of the limiting blocks is the same as that of the vertical plate.

[0023] By adopting the above technical solution, the connection between the ultrasonic probe and the wiring part can be made easier to install and replace the ultrasonic probe.

[0024] Preferably, the rotating structure includes a rotating groove and a sleeve. The rotating groove is formed on the side of the mounting frame near the mounting plate. Side rods are symmetrically installed on both sides of the mounting plate. The sleeve is threaded onto the mounting frame. The side rods are rotatably installed with the sleeve. The mounting plate is rotatably connected to the rotating groove. The side rods are located inside the rotating groove. One end of the sleeve is connected to a turntable, and the turntable is located outside the mounting frame.

[0025] By adopting the above technical solution, the turntable is unscrewed, and the turntable drives the sleeves to be unscrewed, so that the two sleeves are released from pressing on the mounting plate. At this time, the angle of the mounting plate can be adjusted by rotation.

[0026] Preferably, the turntable is fixedly connected to the sleeve, the sleeve is threadedly connected to the mounting frame, the sleeve is located on both sides of the mounting frame, and a round hole is opened on the side of the sleeve near the side rod, and the side rod is rotatably connected to the round hole.

[0027] By adopting the above technical solution, adjusting and then tightening, the sleeves on both sides are pressed against the two sides of the mounting plate again, which facilitates the adjustment and fixation of the incident angle of the ultrasonic probe and improves the ease of use.

[0028] Compared with the prior art, the beneficial effects of the present invention are: it is provided with an installation structure and a rotation structure, and the connecting rod will also drive the locking pin to be locked into the locking groove to realize the positioning of the installation sleeve. When the crossbar is locked in the hole groove of the positioning ring, the positioning sleeve blocks the limiting block, realizing the connection and use of the ultrasonic probe through the connecting rod and the wiring part, and facilitating the adjustment of the ultrasonic probe to different incident angles.

[0029] 1. An installation structure is provided. By placing the workpiece to be inspected on the placement plate inside the water tank and filling the tank with water, servo drive one can achieve X-axis adjustment, servo drive two can achieve Y-axis adjustment, and servo drive three can achieve Z-axis adjustment. This facilitates multi-position adjustment of the ultrasonic probe on servo drive three, improving inspection convenience. When installing the ultrasonic probe, first insert the connecting rod into the mounting plate so that the mounting sleeve is completely locked in the mounting plate. Then rotate the top block, which drives the cylindrical part to rotate. The cylindrical part is threadedly connected to the annular groove, causing the top block to rotate and descend. The top block drives the spiral... The rotating bar causes the top rod to slide towards the center, which in turn drives the arc block to slide. The arc block then drives the connecting rod to move, and the connecting rod slides inside the groove. The connecting rod also drives the locking pin to engage in the groove, thus positioning the mounting sleeve. Next, the outer ring is engaged in the positioning ring, which in turn drives the vertical plate to press down. The vertical plate then drives the horizontal bar to descend. The horizontal bar is compressed by the positioning ring, which compresses the spring until it is engaged in the groove of the positioning ring. Then, the positioning sleeve is pressed down, causing the bottom of the positioning sleeve to block the limiting block. This allows the ultrasonic probe to be connected to the wiring part via the connecting rod, facilitating the installation and replacement of the ultrasonic probe.

[0030] 2. Equipped with a rotating structure, the turntable is screwed outwards, causing the sleeves to unscrew, thus releasing the two sleeves from pressing against the mounting plate. At this point, the angle of the mounting plate can be adjusted by rotating it. The mounting plate drives the side rod to rotate inside the sleeve, and the mounting plate rotates inside the rotating groove. After adjustment, the turntable is tightened again, causing the sleeves on both sides to press against the sides of the mounting plate again. This facilitates the adjustment and fixation of the incident angle of the ultrasonic probe, improving the ease of use and solving the problem that the device is not convenient for easy replacement of ultrasonic sensors and corresponding adjustment of detection angles, which reduces the flexibility of use and the accuracy of non-destructive testing.

[0058] Example 1: As Figure 1 - Figure 9 As shown, by placing the workpiece to be tested on the placement plate inside the water tank 4 and filling the water tank 4 with water, the servo drive 1 can be activated to achieve X-axis adjustment, the servo drive 2 can achieve Y-axis adjustment, and the servo drive 3 can achieve Z-axis adjustment. This facilitates the adjustment of the ultrasonic probe 10 on the servo drive 3 to multiple positions, improving the convenience of testing. The models of the servo drive 1, servo drive 2, servo drive 3 and servo drive 3 can be MINASA6.

[0059] When installing the ultrasonic probe 10, first insert the connecting rod 84 into the mounting plate 83 so that the mounting sleeve 810 is completely locked in the mounting plate 83. Then rotate the top block 85, which drives the cylindrical part 86 to rotate. The cylindrical part 86 is threadedly connected to the annular groove 87, causing the top block 85 to rotate and descend. The top block 85 drives the spiral strip 814 to rotate. The rotation of the spiral strip 814 causes the top rod 815 to slide towards the center. The top rod 815 drives the arc block 813 to slide. The arc block 813 drives the connecting rod 812 to move. The connecting rod 812 slides inside the sliding groove 88. The connecting rod 812 also drives the locking post 89 to lock into the locking groove 811, thereby positioning the mounting sleeve 810.

[0060] Next, the outer ring 818 is inserted into the positioning ring 816. The outer ring 818 drives the vertical plate 819 to press down, and the vertical plate 819 drives the horizontal bar 821 to descend. The horizontal bar 821 is squeezed by the positioning ring 816, and the horizontal bar 821 will compress the spring 820 until the horizontal bar 821 is inserted into the hole groove of the positioning ring 816. Then, the positioning sleeve 817 is pressed down, so that the bottom end of the positioning sleeve 817 blocks the limiting block 822. This realizes the connection between the ultrasonic probe 10 and the wiring part 82 through the connecting rod 84, thereby facilitating the installation and replacement of the ultrasonic probe 10.

[0061] The mounting frame 81 is provided with a rotating structure 9 inside. The rotating structure 9 includes a rotating groove 91 and a sleeve 94. The rotating groove 91 is opened on the side of the mounting frame 81 near the mounting plate 83. Side rods 92 are symmetrically installed on both sides of the mounting plate 83. The sleeve 94 is threaded onto the mounting frame 81. The side rods 92 and the sleeve 94 are rotatably installed.

[0062] Mounting plate 83 is rotatably connected to rotating groove 91, side rod 92 is located inside rotating groove 91, one end of sleeve 94 is connected to turntable 93, and turntable 93 is located outside mounting frame 81.

[0063] The turntable 93 is fixedly connected to the sleeve 94, and the sleeve 94 is threadedly connected to the mounting frame 81. The sleeve 94 is located on both sides of the mounting frame 81. A round hole is opened on the side of the sleeve 94 near the side rod 92, and the side rod 92 is rotatably connected to the round hole.

[0064] Example 2: Figure 10 - Figure 12As shown, by unscrewing the turntable 93 outward, the turntable 93 drives the sleeve 94 to unscrew, thus releasing the two sleeves 94 from pressing against the mounting plate 83. At this time, the angle of the mounting plate 83 can be adjusted by rotation. The mounting plate 83 drives the side rod 92 to rotate inside the sleeve 94, and the mounting plate 83 rotates inside the rotating groove 91. After adjustment, the turntable 93 is tightened again, so that the sleeves 94 on both sides press against the two sides of the mounting plate 83 again, which facilitates the adjustment and fixation of the incident angle of the ultrasonic probe 10, improves the convenience of use, and solves the problem that the device is not convenient for easy replacement of ultrasonic sensors and corresponding detection angle adjustment, which reduces the flexibility of use and the accuracy of non-destructive testing.

[0065] Working principle: When using this device, firstly, as... Figure 1 - Figure 12 As shown, the workpiece to be tested is placed on the placement plate inside the water tank 4, and water is filled into the water tank 4. The servo driver 1 can be started to realize the X-axis adjustment, the servo driver 2 can realize the Y-axis adjustment, and the servo driver 3 can realize the Z-axis adjustment, so that the ultrasonic probe 10 on the servo driver 3 can realize multi-position adjustment and detection.

[0066] When installing the ultrasonic probe 10, first insert the connecting rod 84 into the mounting plate 83. Then rotate the top block 85, which drives the cylindrical part 86 to rotate, causing the top block 85 to rotate and descend. The top block 85 drives the spiral strip 814 to rotate, and the rotation of the spiral strip 814 causes the top rod 815 to slide towards the center. The top rod 815 drives the arc block 813 to slide, and the locking post 89 is locked into the locking groove 811. Next, the outer ring body 818 is locked into the positioning ring 816. The outer ring body 818 drives the vertical plate 819 to press down, and the vertical plate 819 drives the horizontal bar 821 to descend. 821 compresses the spring 820 until the crossbar 821 is stuck in the slot of the positioning ring 816. The bottom end of the positioning sleeve 817 blocks the limiting block 822, realizing the connection of the ultrasonic probe 10 to the wiring part 82 through the connecting rod 84. By unscrewing the turntable 93 outward, the turntable 93 drives the sleeve 94 to unscrew, so that the two sleeves 94 release the pressure on the mounting plate 83. After adjusting the mounting plate 83, tighten the turntable 93 so that the sleeves 94 on both sides press against the two sides of the mounting plate 83 again, which facilitates the adjustment and fixation of the incident angle of the ultrasonic probe 10.
