Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, specifically a nondestructive testing penetration device. Background Technology

[0002] The background technology of non-destructive testing penetrant testing devices is based on the principle of liquid penetrant testing. It uses capillary action to allow penetrant to seep into the defects on the material surface, and then uses a developer to make the penetrant visible, thereby realizing the detection of defects on the material surface. This technology has wide applications in the industrial field, especially in situations where the surface quality requirements of materials are high.

[0003] Existing nondestructive testing penetrant devices, when spraying fluorescent penetrant onto metal objects, sometimes spill the liquid onto the worktable outside the metal objects. This liquid cannot be discharged in time and needs to be disposed of after the test. If it comes into contact with human skin, it may cause certain harm. Therefore, we propose a nondestructive testing penetrant device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a non-destructive testing penetrant device that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-destructive testing permeation device, comprising a main frame, a perforated plate fixedly installed inside the main frame, a waste liquid tank located below the perforated plate inside the main frame, a first L-shaped plate, a second L-shaped plate, and a third L-shaped plate fixedly installed at the top of the main frame, a developer storage tank fixedly installed at the top of the first L-shaped plate, and a fluorescent permeation solution storage tank fixedly installed at the top of the third L-shaped plate, with a water pump fixedly installed on one side of each of the developer and fluorescent permeation solution storage tanks, and hoses fixedly connected to the output ends of both water pumps, with the input ends of the two water pumps extending into the developer and fluorescent permeation solution storage tanks respectively, and one end of each hose passing through the first and third L-shaped plates and fixedly connected to a nozzle, with electric push rods fixedly installed on one side inside each of the first and third L-shaped plates, and connecting blocks fixedly connected to the output ends of each of the two electric push rods. The connecting block is fixedly connected to the outside of the two hoses. Two electric push rods are fixedly installed at the bottom of the second L-shaped plate. The output ends of the two electric push rods are fixedly connected to the mounting frame. A motor is fixedly installed on one side of the mounting frame. Cleaning rollers are rotatably connected to the two sides of the mounting frame that are close to each other. One end of the cleaning roller passes through one side of the mounting frame and is fixedly connected to the output end of the motor. Two extension plates are fixedly installed at the top of the main frame. Two sliding rods are fixedly connected between the two extension plates. Adjusting blocks are slidably connected to the outside of the two sliding rods. Adjusting columns are fixedly connected to the bottom of the adjusting blocks. A lamp board is rotatably connected to the bottom of the adjusting columns. Several ultraviolet lamp beads are set at the bottom of the lamp board. A workbench is fixedly installed inside the main frame and is located below the lamp board. When performing non-destructive testing penetration, one nozzle is first used to spray fluorescent penetrant onto the surface of the metal parts. Then, the cleaning roller is used to clean the surface of the metal parts. Then, the other nozzle is used. A developer is sprayed onto the surface of the metal parts, and then the test results are obtained by irradiation with ultraviolet light beads. The fluorescent penetrant and developer sprayed on the outside of the metal parts will fall onto the top of the stencil and then into the waste liquid tank. This process makes the test more convenient and allows for timely treatment of the waste liquid.

[0006] Preferably, two extension plates are fixedly installed on one side of the main frame, and a motor is fixedly installed on one side of one of the extension plates. A screw is rotatably connected between the two extension plates. One end of the screw passes through one of the extension plates and is fixedly connected to the output end of the motor. A sliding groove is opened on one side of the inside of the main frame. A moving block is threadedly connected to the outside of the screw. The moving block is slidably connected to the sliding groove. During testing, the screw is rotated by the operation of the motor, thereby moving the metal part to the required position.

[0007] Preferably, a movable frame is fixedly connected to one side of the movable block, and a second sliding groove is provided on one side of the movable frame. A bidirectional lead screw is rotatably connected to the two sides of the movable frame that are close to each other. A second motor is fixedly installed on one side of the movable frame. One end of the bidirectional lead screw passes through the movable frame and is fixedly connected to the output end of the second motor. A limit groove is provided on one side of the main frame. The limit groove cooperates with one end of the movable frame. Two clamping plates are threaded to the outside of the bidirectional lead screw. The two clamping plates cooperate with the second sliding groove. When it is necessary to clamp a metal part, the second motor drives the bidirectional lead screw to rotate, which makes the two clamping plates close to each other, thereby clamping the metal part.

[0008] Preferably, an injection pipe is fixedly connected to one side of both the developer storage tank and the fluorescent permeate storage tank, and a drain pipe is fixedly connected to the bottom of the waste liquid tank. Before detection, the corresponding liquid is injected into the developer storage tank and the fluorescent permeate storage tank through the injection pipe.

[0009] Preferably, a control panel is fixedly installed on one side of the main frame, and a support leg is fixedly installed at the bottom of the main frame.

[0010] Preferably, the water pump, motor one, motor two, motor three, electric actuator one, and electric actuator two are all electrically connected to the control panel.

[0011] This invention provides a non-destructive testing penetrant device, which has the following advantages:

[0012] 1. This non-destructive testing penetrant device, through the setting of the perforated plate, allows fluorescent penetrant sprayed outside the metal object to fall onto the perforated plate during the penetrant testing process. It then falls into the waste liquid tank through the small holes on the perforated plate and can be discharged through the drain pipe. This process allows for timely discharge of waste liquid, preventing it from being left on the operating table and avoiding any harm to human skin from contact with the waste liquid.

[0013] 2. This non-destructive testing penetrant device, with its two nozzles, cleaning roller, and lamp plate, allows for step-by-step testing, reducing the time required for manual intervention. This design makes testing more convenient and indirectly improves work efficiency. Attached Figure Description

[0025] like Figure 2 As shown, injection pipes 27 are fixedly connected to one side of the developer storage tank 5 and the fluorescent permeate storage tank 6. The injection pipes 27 are used to inject the corresponding liquids into the developer storage tank 5 and the fluorescent permeate storage tank 6.

[0026] like Figure 2 As shown, a control panel 20 is fixedly installed on one side of the main frame 1. The control panel 20 is used to control this device. A support leg 28 is fixedly installed at the bottom of the main frame 1. The support leg 28 is used to support this device.

[0027] like Figure 1 As shown, water pump 7, motor 1 9, motor 2 13, motor 3 21, electric actuator 1 22 and electric actuator 2 25 are all electrically connected to control panel 20, and water pump 7, motor 1 9, motor 2 13, motor 3 21, electric actuator 1 22 and electric actuator 2 25 are all connected to power cords.

[0028] In summary, when using this non-destructive testing penetrant device, the operator first injects developer and fluorescent penetrant into the developer storage tank 5 and fluorescent penetrant storage tank 6 respectively using two injection tubes 27. After injection, the metal part to be tested (such as a 1.5*3.0 square tube) is placed between the two clamping plates 15. Then, the motor 13 is started using the control panel 20. The motor 13 drives the bidirectional lead screw 14 to rotate, thereby bringing the two clamping plates 15 closer together and clamping the metal part. Note that the flat side of the metal part should face upwards and be higher than the top of the clamping plate 15. Then, it can be used... Motor 9 operates, driving screw 10 to rotate, which in turn moves moving block 11 on slide groove 104, indirectly moving moving frame 12. The metal object is then moved to the bottom of the third L-shaped plate 4. Water pump 7 on one side of fluorescent penetrant storage tank 6 is then turned on, spraying fluorescent penetrant from nozzle 26 at the bottom of the third L-shaped plate 4 onto the surface of the metal object. Electric push rod 25 at the bottom of the third L-shaped plate 4 is used to ensure the surface of the metal object is completely coated with fluorescent penetrant. After a period of time, allowing the fluorescent penetrant to penetrate into the opening defects of the metal object, motor 9 is turned on again. The process involves moving the metal object to the bottom of the second L-shaped plate 3, then using two electric push rods 22 to move the cleaning roller 24 to the surface of the metal object. Motor 21 is then activated to rotate the cleaning roller 24, removing excess fluorescent penetrating liquid from the surface of the metal object. It is crucial that no fluorescent penetrating liquid remains on the surface of the metal object. Motor 9 is then used again to move the metal object to the bottom of the first L-shaped plate 2. At this point, the water pump 7 on one side of the developer storage tank 5 sprays the developer from the nozzle 26 at the bottom of the first L-shaped plate 2 onto the surface of the metal object. After spraying, motor 9 is used to remove excess fluorescent penetrating liquid from the surface of the metal object. The object is moved onto the workbench 30, and then the operator turns on the lamp panel 19 to activate the ultraviolet lamp beads 191, and begins to irradiate the surface of the metal object. The operator can adjust the position of the lamp panel 19 by moving the adjustment block 17, and can also rotate the lamp panel 19 to adjust the angle. If fluorescence appears on the surface of the irradiated metal object, it indicates that there is an opening defect. If there is no fluorescence, it indicates that there is no opening defect in the metal object. Through the setting of the stencil 16, during the detection process, excess fluorescent penetrant and developer will fall into the waste liquid tank 29, and can then be discharged through the drain pipe 291. The above is the working principle of this utility model.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
