Description

Technical Field

[0001] This utility model belongs to the field of fluorescent penetrant detection line technology, specifically relating to a fluorescent penetrant detection line penetrant device. Background Technology

[0002] Fluorescent penetrant testing lines are highly efficient non-destructive testing devices used to detect surface defects in workpieces, and are widely used in aerospace, automotive manufacturing, and rail transportation industries. This testing line applies a fluorescent penetrant to the workpiece surface, utilizing capillary action to allow the penetrant to penetrate the surface defects. After cleaning and development steps, the fluorescence is observed under ultraviolet light, thus identifying and assessing the location and size of the defects. Fluorescent penetrant testing lines are characterized by high sensitivity, high efficiency, and wide applicability, effectively detecting minute surface defects such as cracks and pores, ensuring the quality and safety of workpieces.

[0003] The penetrant device of a fluorescent penetrant testing line is used to apply fluorescent penetrant to the surface of the workpiece being tested. However, during long-term use, the fluorescent penetrant itself will precipitate and a small amount of impurities will adhere to the inner wall. The attached impurities may contaminate the newly added fluorescent penetrant in subsequent uses, changing its chemical composition and physical properties, and reducing the detection sensitivity. To address this, we propose a penetrant device for a fluorescent penetrant testing line. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a fluorescence penetrant detection line penetrant device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fluorescence penetrant detection line penetrant device includes: a penetrant chamber, the top of which is rotatably connected to a connecting top cover; characterized in that: multiple sliding grooves are provided on both sides of the inner wall of the penetrant chamber, penetrant components are provided on the inner walls of the multiple sliding grooves, movable components are provided on the inner walls of the penetrant components, and the size of the penetrant components matches the size of the inner wall of the penetrant chamber.

[0007] The workpiece to be tested is placed on the inner wall of the permeation assembly, and the structure of the permeation assembly is used to perform a covering permeation on the surface of the workpiece. When the workpiece is removed after permeation, the permeation assembly can scrape off the inner wall of the permeation chamber to prevent the permeating agent residue from adhering to the inner wall of the permeation chamber.

[0008] Preferably, the permeation assembly includes a limiting slide rail, an electric lifting block, a connecting frame, a movable groove, a workpiece placement box, a fluorescent permeate inlet hole, and an impurity scraper. The limiting slide rail is fixedly connected to the inner wall of the sliding groove, the electric lifting block is slidably connected to the surface of the limiting slide rail, and the connecting frame is fixedly connected between multiple electric lifting blocks.

[0009] Preferably, the movable groove is formed on the inner wall of the connecting frame, the workpiece placement box is fixedly connected to the bottom of the connecting frame, the fluorescent permeate inlet is formed on the surface of the workpiece placement box, the impurity scraper is fixedly connected to the bottom surface of the workpiece placement box, and the position of the impurity scraper matches the inner wall of the permeation chamber.

[0010] Preferably, the movable components include an impurity inlet, a cleaning tank, a liquid filter, a cleaning slide rail, a cleaning slider, a connecting rod, a pick-up block, and an impurity outlet. Multiple impurity inlets are formed on the inner wall surface of the impurity scraper, the cleaning tank is formed on the inner wall of the impurity scraper, and the liquid filter is fixedly connected to the bottom of the cleaning tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The sliding groove helps to provide space for the movement of the entire permeation module. The permeation module can use its own structure to help place the entire workpiece in the fluorescent permeate inside the permeation box for coverage permeation without contaminating its own structure with fluorescent permeate. This ensures uniform permeation without affecting the overall permeation module. Furthermore, during the process of removing the workpiece after permeation, impurities inside the permeation box are treated to prevent adsorption. The treated impurities can be easily discharged through the structure of the moving component, thereby further improving the functionality of the device.

[0016] 2. The overall structure of the permeation assembly helps clean impurities inside the permeation chamber during the permeation process. A limit slide rail drives the electric lifting block to move up and down, which in turn moves the connecting frame and the workpiece placement box. The workpiece to be tested, placed inside the placement box, is immersed in the fluorescent permeate as it moves up and down. The fluorescent permeate then soaks the workpiece through the inlet hole, achieving a comprehensive permeation. Simultaneously, the up-and-down movement causes an impurity scraper to scrape away impurities from the inner wall of the permeation chamber. This process effectively cleans impurities adhering to the inner wall of the permeation chamber, further enhancing the device's functionality. Attached Figure Description

[0025] 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.

[0026] Example

[0027] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0028] Example 1:

[0029] A fluorescence permeation detection line permeation device includes: a permeation chamber 1, a connecting top cover 2 rotatably connected to the top of the permeation chamber 1, characterized in that: multiple sliding grooves 6 are provided on both sides of the inner wall of the permeation chamber 1, a permeation component 7 is provided on the inner wall of the multiple sliding grooves 6, a movable component 8 is provided on the inner wall of the permeation component 7, the size of the permeation component 7 matches the size of the inner wall of the permeation chamber 1, an observation transparent window 3 is fixedly connected to the inner wall of the connecting top cover 2, a light shield 4 is rotatably connected to one side of the observation transparent window 3, a lifting handle 5 is fixedly connected to the top of the light shield 4, and an outlet pipe 9 is fixedly connected to the back of the permeation chamber 1, with a sealing cap 10 provided at one end of the outlet pipe 9;

[0030] The workpiece to be tested is placed on the inner wall of the permeation component 7, and the structure of the permeation component 7 is used to perform a covering permeation on the surface of the workpiece. When the workpiece is removed after permeation, the permeation component 7 can scrape off the inner wall of the permeation chamber 1 to prevent the permeating agent residue from adhering to the inner wall of the permeation chamber 1.

[0031] In this embodiment, the permeation chamber 1 provides space for the fluorescent penetrant inside the device, the top cover 2 helps to seal the device from the top, the observation window 3 allows the user to observe the inside of the permeation chamber 1, and the light shield 4 can be used when needed to block light from entering the permeation chamber 1, thereby facilitating the permeation of the fluorescent penetrant. The lifting handle 5 provides a point of leverage for the user to lift the light shield 4, the sliding groove 6 provides a range of motion for the permeation assembly 7, the permeation assembly 7 uses its own structure to help perform a covering permeation of the workpiece, and scrapes impurities off the inner wall of the permeation chamber 1 during the permeation process. After the impurities are scraped off, the structure of the movable assembly 8 can be used to clean and discharge the impurities for subsequent use, thereby further improving the functionality of the device. The liquid outlet pipe 9 provides an outlet for the device to remove impurities, and the sealing cover 10 helps to seal the interior when needed.

[0032] The permeation assembly 7 includes a limiting slide rail 701, an electric lifting block 702, a connecting frame 703, a movable groove 704, a workpiece placement box 705, a fluorescent permeate inlet 706, and an impurity scraper 707. The limiting slide rail 701 is fixedly connected to the inner wall of the sliding groove 6, the electric lifting block 702 is slidably connected to the surface of the limiting slide rail 701, and the connecting frame 703 is fixedly connected between multiple electric lifting blocks 702.

[0033] In this embodiment, the permeation component 7 uses the limiting slide rail 701 to drive the electric lifting block 702 to move up and down as a whole. The electric lifting block 702 has a built-in drive motor adapted to the limiting slide rail 701, which can effectively lift and lower on the surface of the limiting slide rail 701. The lifting function achieved by this structure is a device and principle well known to those skilled in the art, and will not be described in detail here. The electric lifting block 702 drives the connecting frame 703 to move up and down as a whole, thereby providing the basis for the permeation component 7 to perform coverage permeation.

[0034] The movable groove 704 is opened on the inner wall of the connecting frame 703, the workpiece placement box 705 is fixedly connected to the bottom of the connecting frame 703, the fluorescent penetrant inlet hole 706 is opened on the surface of the workpiece placement box 705, the impurity scraper 707 is fixedly connected to the bottom surface of the workpiece placement box 705, and the position of the impurity scraper 707 matches the inner wall of the penetrant box 1.

[0035] In this embodiment, the movable groove 704 can provide movable space for the movable component 8. The workpiece placement box 705 can use its internal space to place the workpiece to be tested. At the same time, when the electric lifting block 702 lowers the workpiece placement box 705, the fluorescent penetrant will be immersed in through the fluorescent penetrant inlet hole 706 to cover the workpiece, thereby ensuring uniform coverage of the penetrant. Meanwhile, when the electric lifting block 702 moves up and down, the impurity scraper 707 will scrape off impurities on the inner wall of the penetrant box 1, thereby ensuring the cleanliness of the inner wall of the penetrant box 1 and preventing subsequent impact on the newly added fluorescent penetrant.

[0036] Example 2:

[0037] Based on Embodiment 1, this embodiment considers that only Embodiment 1 can achieve the removal of impurities from the inner wall of the permeation tank 1. However, in practical use, there is still a risk that the removed impurities may re-adhere to the inner wall of the permeation tank 1. Therefore, this embodiment uses the following structure to temporarily store the impurities and help with subsequent cleaning.

[0038] The active component 8 includes an impurity inlet 801, a cleaning tank 802, a liquid filter 803, a cleaning slide rail 804, a cleaning slider 805, a connecting rod 806, a pick-up block 807, and an impurity outlet 808. Multiple impurity inlets 801 are opened on the inner wall surface of the impurity scraper 707, the cleaning tank 802 is opened on the inner wall of the impurity scraper 707, and the liquid filter 803 is fixedly connected to the bottom of the cleaning tank 802.

[0039] In this embodiment, the movable component 8 guides the impurities scraped by the impurity scraper 707 into the cleaning tank 802 through the groove and shape of the impurity inlet 801. During the process of the electric lifting block 702 rising, water and other liquids are discharged from the liquid filter 803. The force when it is pulled up ensures that the impurities are collected on the surface of the liquid filter 803, thereby completing the overall collection of impurities.

[0040] The cleaning slide rail 804 is fixedly connected to both sides of the inner wall of the cleaning tank 802. The cleaning slider 805 is slidably connected to the surface of the cleaning slide rail 804. The connecting rod 806 is fixedly connected to the top of the cleaning slider 805. The position of the connecting rod 806 matches the movable tank 704. The pick-up block 807 is fixedly connected to the top of the connecting rod 806. The impurity outlet 808 is located on one side of the impurity scraper 707.

[0041] In this embodiment, the cleaning slide rail 804 can help limit and guide the sliding cleaning of the cleaning slider 805. The shape of the cleaning slider 805 is adapted to the liquid filter 803. The user can use the connecting rod 806 and the pick-up block 807 to drive the cleaning slider 805 to slide and remove impurities from the liquid filter 803 and discharge them through the impurity outlet 808. At this time, after the user replaces the fluorescent permeating solution with clean water, the impurities can be directly absorbed and discharged through the clean water, thereby completing the cleaning of impurities and further improving the functionality of the device.

[0042] Working principle: The fluorescent permeate is placed in the permeation chamber 1. After the permeation is complete, the permeate is discharged through the outlet pipe 9, and water is added for easy cleaning, thus improving the functionality of the device. The top cover 2 helps to seal the inside of the permeation chamber 1 from the top. The observation window 3 allows the user to directly observe the inner wall of the permeation chamber 1 and can be linked with the light shield 4. When needed, the light shield 4 can be used to close the observation window 3 to prevent light from entering, thereby increasing the permeation effect of the fluorescent permeate. The lifting handle 5 helps the user open the light shield 4, providing a point of leverage. The moving tank 6 provides space for the overall movement of the permeation assembly 7. The permeation assembly 7 can use its own structure to help place the workpiece in the fluorescent permeation agent inside the permeation tank 1 for a comprehensive permeation without contaminating its own structure with fluorescent permeation agent. This ensures uniform permeation without affecting the overall permeation assembly 7. Furthermore, during the process of removing the workpiece after permeation, impurities inside the permeation tank 1 are treated to prevent adsorption. The treated impurities can be easily discharged through the structure of the moving assembly 8. Subsequently, impurities can be removed by discharging the fluorescent permeation liquid, thereby further improving the functionality of the device and its overall service life.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
