Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, specifically to an ultrasonic detection coupling fluid coating and collection mechanism. Background Technology

[0002] Ultrasonic testing is a commonly used non-destructive testing method widely applied to the detection of internal defects in metal sheets. During ultrasonic testing, a coupling fluid needs to be applied to the surface of the sheet to eliminate air between the probe and the sheet, thereby improving sound wave transmission efficiency. Traditionally, the application of the coupling fluid is mostly done manually, which is inefficient and results in uneven application.

[0003] An existing patent (CN220399336U) discloses an ultrasonic flaw detection device for metal welding. By setting up an automatic oiling mechanism, it uses a rolling roller to automatically apply oil from an oil storage tank to the surface of the metal welded plate, and cooperates with a servo motor to drive the probe to move for flaw detection, which significantly improves the automation level of oiling and detection.

[0004] However, the device still has the following shortcomings in practical applications: a large amount of coupling fluid coated on the surface of the plate remains on the surface of the plate after the test is completed. The device does not have a recycling structure, which results in the waste of coupling fluid. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an ultrasonic detection coupling fluid coating and collection mechanism. By setting a scraper, the excess coupling fluid on the surface of the plate is automatically scraped off after ultrasonic detection, so as to realize the automatic collection and recycling of coupling fluid and reduce material waste.

[0006] The technical solution adopted in this utility model is as follows: An ultrasonic detection coupling fluid coating and collection mechanism includes a transmission plate, and above the transmission plate, from front to back, are a coating mechanism, a detection mechanism and a scraper; It also includes a drive mechanism and a pusher plate. The transmission plate is provided with side limiting plates on both sides. The drive mechanism can drive the pusher plate to push the plate from the front end to the rear end of the transmission plate. The plate slides between the two side limiting plates. The plate passes through the coating mechanism and the detection mechanism in sequence. The coating mechanism is used to coat the plate with coupling liquid. The detection mechanism is used to perform ultrasonic testing on the plate. The bottom surface of the scraper can contact the top surface of the plate. The pusher plate has a first groove on the side near the material, and the conveyor plate has a second groove. A collection groove is provided below the second groove. The pusher plate ensures that the first groove and the second groove are aligned when the material has completely passed through the scraper.

[0007] Working principle: With the above settings, the plate to be tested can be placed at the front end of the transfer plate, and limited by two side limiting plates on both sides. The drive mechanism drives the pusher plate to move, which allows the plate to slide on the transfer plate. When the plate passes through the coating mechanism, it is coated with coupling liquid. When it passes through the detection mechanism, it is detected. Finally, when it passes through the scraper, the scraper moves relative to the plate, and the coupling liquid on the plate is pushed to the front end. When the plate has completely passed through the detection mechanism, the scraper pushes the coupling liquid to the first slot and flows into the collection tank through the second slot.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a scraper, excess coupling fluid on the surface of the material is automatically scraped off after ultrasonic testing. By setting a first slot on the push plate, a second slot on the transfer plate, and a collection tank below, the two slots are aligned when the material passes completely through the scraper. The coupling fluid scraped off by the scraper can flow smoothly into the collection tank through the first and second slots, realizing the automatic collection and recycling of coupling fluid and reducing material waste.

[0009] In a preferred embodiment of the present invention, the coating mechanism includes a frame, a rotating roller, and an oil supply unit. The oil supply unit supplies oil to the rotating roller, which is rotatably mounted on the frame and can be in close contact with the upper surface of the plate.

[0010] Beneficial effects: The rotating roller is kept wetted by the coupling liquid under the oil supply of the oil supply unit and is in close contact with the upper end surface of the plate. When the plate is pushed forward, the rotating roller is passively rotated by friction, so as to evenly and continuously coat the plate surface with the coupling liquid.

[0011] In a preferred embodiment of this utility model, the rotating roller includes a rod and a sponge tube, the rod is rotatably mounted on the frame, and the sponge tube is sleeved on the rod.

[0012] Beneficial effects: The sponge tube has a good ability to absorb and release coupling fluid. It can store a certain amount of coupling fluid and seep out evenly when under pressure, ensuring a stable and uniform coating process. The sponge material is soft and will not scratch the surface of the sheet, making it suitable for metal sheets with high surface quality requirements.

[0013] In a preferred embodiment of the present invention, the oil supply unit includes a fixing plate, the top of the fixing plate is provided with a liquid inlet, the liquid inlet is connected to the liquid supply pipe, the bottom of the fixing plate is provided with a through groove, the through groove is provided with a water distribution plate, the water distribution plate is provided with multiple liquid outlets, and the top of the sponge tube rests against the multiple liquid outlets.

[0014] Beneficial effects: The coupling liquid is evenly distributed to the sponge tube through multiple outlets, ensuring uniform adsorption along the length of the sponge tube, thereby making the coating amount consistent in the width direction of the plate; the water distribution plate and the through groove have a compact fit structure, stable liquid supply, and the sponge tube directly abuts against the outlet, which can continuously replenish the liquid.

[0015] In a preferred embodiment of this utility model, the driving mechanism includes a driving motor, a rack is provided on one side of the transmission plate, a guide groove is provided on the side limiting plate near the rack, the output shaft of the driving motor is equipped with a gear that meshes with the rack, the driving motor is mounted on a mounting plate, a connecting plate is provided on the mounting plate, the connecting plate passes through the guide groove and is fixedly connected to the pusher plate, and the connecting plate can slide along the guide groove.

[0016] Beneficial effects: The gear and rack transmission method, combined with the guide groove and connecting plate, enables the smooth and precise linear movement of the push plate; the guide groove is opened on the side limiting plate, which also serves to guide and limit the connecting plate, eliminating the need for additional guide rails.

[0021] See Figure 1 and Figure 2 As shown in the figure, this embodiment discloses an ultrasonic detection coupling fluid coating and collection mechanism, including a transmission plate 1, a driving mechanism 2, and a pushing plate 3. The transmission plate 1 is provided with a coating mechanism 4, a detection mechanism 5, a scraper 6, and a collection tank 7 from front to back above it.

[0022] The testing mechanism 5 includes multiple ultrasonic probes, which are vertically mounted on the frame and can be attached to the top of the plate 8 for testing.

[0023] The transmission plate 1 is provided with side limiting plates 11 on both sides. When testing, the plate 8 is placed on the transmission plate 1, and the plate 8 is limited on both sides by the side limiting plates 11.

[0024] Among them, see Figure 1 As shown, the driving mechanism 2 includes a drive motor 21. A rack 22 is provided on one side of the transmission plate 1. A guide groove 12 is provided on the side limiting plate 11 near the rack 22. A gear 25 meshing with the rack 22 is mounted on the output shaft of the drive motor 21. The drive motor 21 is mounted on a mounting plate 23. A connecting plate 24 is provided on the mounting plate 23. The connecting plate 24 passes through the guide groove 12 and is fixedly connected to the pusher plate 3. The connecting plate 24 can slide along the guide groove 12. The drive motor 21, through the gear 25 and rack 22, enables the pusher plate to move along the guide groove 12 and push the material plate 8.

[0025] In other embodiments, the drive motor 21 may be a motor-driven lead screw with a slider on it, which drives the pusher plate 3 to move.

[0026] Among them, see Figure 2 and Figure 4As shown, the coating mechanism 4 includes a frame 41, a rotating roller 42, and an oil supply section 43. The oil supply section 43 supplies oil to the rotating roller 42, which is rotatably mounted on the frame 41. The rotating roller 42 includes a rod 421 and a sponge tube 422. The rod 421 is rotatably mounted on the frame 41, and the sponge tube 422 is sleeved on the rod 421. The oil supply section 43 includes a fixing plate 431. The top of the fixing plate 431 is provided with a liquid inlet 432, which is connected to the liquid supply pipe 433. The bottom of the fixing plate 431 is provided with a through groove 434, and a water distribution plate 435 is provided in the through groove 434. The water distribution plate 435 is provided with multiple liquid outlets 436, and the top of the sponge tube 422 rests against the multiple liquid outlets 436.

[0027] In this embodiment, the liquid supply pipe 433 delivers coupling fluid through the pump body. In other embodiments, a large-capacity liquid storage tank can be set up directly above the through channel 434 for oil supply.

[0028] Among them, see Figure 3 As shown, the pusher plate 3 has a first slot 31 near the plate 8, and the transfer plate 1 has a second slot 13. The collection tank 7 is located below the second slot 13. The pusher plate 3 ensures that the first slot 31 and the second slot 13 are aligned when the plate 8 has completely passed the scraper plate 6. When the plate 8 finally passes the scraper plate 6, the scraper plate 6 moves relative to the plate 8, and the coupling liquid on the plate 8 is pushed towards the front end. After the plate 8 has completely passed the detection mechanism 5, the scraper plate 6 pushes the coupling liquid towards the first slot 31 and flows into the collection tank 7 through the second slot 13.

[0029] In this embodiment, the bottom of the scraper 6 is provided with a rubber layer to ensure the removal of the coupling fluid.

[0030] With the above settings, the plate 8 to be tested can be placed at the front end of the transmission plate 1, and limited on both sides by two side limiting plates 11. The driving mechanism 2 drives the pusher plate 3 to move, so that the plate 8 can slide on the transmission plate 1. When the plate 8 passes through the coating mechanism 4, the sponge cylinder 422 rotates by friction to apply coupling liquid. When it passes through the detection mechanism 5, it is tested. Finally, when it passes through the scraper 6, the scraper 6 moves relative to the plate 8, and the coupling liquid on the plate 8 is pushed to the front end. When the plate 8 has completely passed through the detection mechanism 5, the scraper 6 pushes the coupling liquid to the first slot 31 and flows into the collection tank 7 through the second slot 13.
