Description

Technical Field

[0001] The present invention relates to the technical field of fluorescent penetrant testing, and more specifically, to a modular penetrant tank integrated structure applied to a fluorescent penetrant testing line. Background Art

[0002] Fluorescent penetrant testing is a commonly used non-destructive testing method. A penetrant containing a fluorescent dye is used to penetrate the tiny pores or defects on the surface of the object to be tested. After removing the excess penetrant, ultraviolet light is used to irradiate the fluorescent dye in the defects to emit light, so as to achieve rapid and accurate detection of the surface defects of the object to be tested. The penetrant tank is a key component in the fluorescent penetrant testing system.

[0003] However, when the prior art uses the fluorescent penetrant method to detect the product to be tested, most of them need to position the product to be tested through a clamping structure, and use a driving clamping mechanism to drive the product to be tested to move in the penetrant tank. For example, the patent with the publication number CN111948221A involves "A fluorescent tank liquid device for soaking steering knuckles and a detection method", in which a suspension chain for moving the steering knuckle is arranged in the fluorescent tank liquid device, and a fluorescent detection sling for positioning the steering knuckle is arranged on the suspension chain; although the steering knuckle can be moved from the penetrant tank to the buffer chamber and the reflux chamber, the fluorescent detection sling needs to be positioned with the product to be tested. On the one hand, it is not convenient for rapid operation, and on the other hand, there is a fixed contact surface between the two, resulting in that the contact surface part of the product to be tested cannot be penetrated by the penetrant, and there are detection limitations.

[0004] Another example is the patent with the publication number CN222671709U, which involves "A fluorescent penetrant testing device". The bearing collar is sleeved into the collar device, and then the spray nozzle sprays the fluorescent penetrant on the surface of the object to be tested. However, since the bearing collar is horizontally sleeved on the horizontally arranged collar device by the shaft hole, and the spray nozzle is fixedly arranged vertically downward, it is difficult to change the positions of the end faces of the bearing collar during the penetration process, and it is difficult to achieve uniform spraying of the spray agent on all parts of the bearing collar. Therefore, in view of the above problems, a modular penetrant tank integrated structure applied to a fluorescent penetrant testing line is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems, and now a modular penetrant tank integrated structure applied to a fluorescent penetrant testing line is provided.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A modular penetrant tank integrated structure applied to a fluorescent penetrant testing line includes a horizontally arranged penetrant tank, a draining tank, and a filtering tank that communicates with both of them. The filtering tank is internally and circularly communicated with the penetrant tank through a reflux pipe;

[0007] On the upper conveying end of the side of the permeation tank away from the liquid draining tank, a feeding component for conveying the product to be tested is embedded and installed. Inside the permeation tank, a plurality of permeation raceways are fixedly installed, which are adapted to the feeding component and are inclined downward away from the feeding component. One end of the reflux pipe away from the filtering tank is fixed with a spray head that penetrates the inner wall of the permeation tank and corresponds to the upper conveying end of the permeation raceway;

[0008] On the left and right sides inside the permeation tank, a limiting component and a material turning component acting on the upper and lower ends of the permeation raceway are respectively installed. At the front and rear ends of the side of the permeation tank close to the liquid draining tank, electric push cylinders for lifting and driving the material turning component are fixed;

[0009] The material turning component includes a lifting seat fixedly installed at the telescopic ends of a pair of electric push cylinders. Positioning plates are fixed on the opposite end walls of the pair of lifting seats. A turning plate is rotatably installed between the pair of positioning plates, and a plurality of material receiving structures corresponding to the position of the permeation raceway are fixed on the turning plate.

[0010] Further, the feeding component includes feeding chutes that are inclined downward and embedded at the upper end of the permeation tank and correspond to a plurality of positions of the permeation raceways. The outer ends of the plurality of feeding chutes are commonly connected to a feeding plate, and a feeding groove communicating with the feeding chutes is opened on the feeding plate. One end of the feeding chute away from the feeding plate is fixed with a baffle channel extending above the upper conveying end of the permeation raceway, and a blanking groove opening is opened at the bottom end of the baffle channel.

[0011] Further, an installation cavity for embedding and installing the feeding chute is opened on one side of the upper end of the permeation tank. The baffle channel is an L-shaped structure extending upward away from one end of the feeding chute, and the blanking groove opening corresponds to directly above the upper conveying end of the permeation raceway.

[0012] Further, a number of through holes are opened on each end face of the permeation raceway. The internal width of the permeation raceway is slightly larger than the thickness of the product to be tested, and the internal height of the permeation raceway is smaller than the inner radius size of the product to be tested.

[0013] Further, the material receiving structure includes an arc-shaped material receiving plate fixed to the bottom end of the turning plate and having the same internal width as the permeation raceway. On both sides of the upper end of the arc-shaped material receiving plate, side guide discs II concentric with it are fixed, and an arc-shaped surface adapted to the structure of the side guide discs II is opened on the inner end face of the turning plate.

[0014] Further, a hollow groove corresponding to the position of the arc-shaped material receiving plate is opened on the bottom wall of the lower conveying end of the permeation raceway. One end of the arc-shaped material receiving plate away from the turning plate is provided with an extension part that is arranged upward along the inclined surface of the permeation raceway and is embedded in the hollow groove.

[0015] Further, the limiting component includes an arc-shaped limiting plate rotatably installed on the bottom wall of the conveying end of the penetration raceway. On both the front and rear sides of the arc-shaped limiting plate, there are side guide discs one fixedly installed and movably embedded in the front and rear inner walls of the conveying end of the penetration raceway.

[0016] Further, a turning cavity is opened at the end of the penetration groove close to the liquid draining groove. At the bottom end of the turning cavity, a plurality of filtrate raceways corresponding to the positions of the penetration raceways are embedded and installed. The other end of the filtrate raceway is inclined downward and fixed to the inner end wall of the liquid draining groove.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] First, this solution uses a penetration groove, a liquid draining groove, and a filtering groove to cooperate with each other to form an overall modular penetration groove integrated structure, realizing the circulating filtration and circulation of the penetrant. And in the penetration groove of the main penetration process, a plurality of penetration raceways arranged obliquely downward and completely immersed in the penetrant are provided. The inclined raceways are suitable for ring-shaped products, such as bearings and round tube products. During the rolling process, the upper end of the product to be tested is always exposed above the penetration raceway. On the one hand, with the help of the inclined raceway, long-distance conveying and penetration of the product to be tested can be realized without using any clamping structure for positioning. On the other hand, during the continuous rolling and turning process, the end faces of the product to be tested can be effectively brought into full contact with the penetrant, improving the penetration effect.

[0019] Second, this solution also configures a limiting component and a turning component acting on the product to be tested at the upper and lower conveying ends of the penetration raceway respectively. The setting of the limiting component is used to play a role of timing feeding for the product to be tested conveyed from the feeding component to the upper conveying end of the penetration raceway. By relying on the periodic repeated rotation of the limiting component, multiple products to be tested are synchronously and regularly conveyed downward along the inclined conveying path of the penetration raceway. And the turning component arranged at the lower conveying end of the penetration raceway is used to receive the product to be tested that rolls downward, and under the action of the electric push cylinder, lift the product to be tested upward to the turning cavity. At this time, by using the flipping of multiple groups of receiving structures, the penetrated product to be tested is flipped outward to the filtrate raceway, realizing an unobstructed penetration route of "directional inclined conveying, long-distance rolling penetration, and running and rolling liquid draining".

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work shall fall within the scope of protection of the present invention.

[0037] Example 1: To address the problem that the fluorescent penetrant testing device uses a fixed structure to position the product to be tested, making it difficult for all end faces of the product to be tested to be fully penetrated by the penetrant, resulting in poor penetrant testing results, the following technical solution is proposed, which is mainly suitable for penetrant testing of rings and discs:

[0038] This embodiment relates to a modular penetration tank integrated structure used in a fluorescent penetrant detection line. Figure 1 , including a horizontally arranged infiltration tank 1, a leachate tank 2, and a filter tank 3 interconnected with the infiltration tank 1 and the leachate tank 2, and the filter tank 3 is connected to the internal circulation of the infiltration tank 1 through a reflux pipe 11;

[0039] A loading assembly 4 for conveying the product 5 to be tested is embedded in the upper conveying end of the infiltration tank 1 away from the leachate tank 2. A plurality of infiltration rollers 6 adapted to the loading assembly 4 and inclined downwardly toward the side away from the loading assembly 4 are fixedly installed inside the infiltration tank 1. A spray head 111 is fixed on the end of the return pipe 11 away from the filter tank 3, which passes through the inner wall of the infiltration tank 1 and corresponds to the position of the upper conveying end of the infiltration roller 6.

[0040] See also Figures 2 - 3 The feeding assembly 4 includes a feeding chute 41 which is embedded and installed at the upper end of the infiltration groove 1 and corresponds to the position of the infiltration roller 6. The outer ends of the multiple feeding chutes 41 are commonly connected with a discharge plate 42. The discharge plate 42 is provided with a discharge trough connected to the feeding chute 41. The feeding chute 41 is fixed with a blocking channel 43 extending to above the upper conveying end of the infiltration roller 6 at one end away from the discharge plate 42, and a blanking notch 431 is provided at the bottom of the blocking channel 43. A placement cavity 101 for embedding and installing the feeding chute 41 is provided on one side of the upper end of the infiltration groove 1. The blocking channel 43 is an L-shaped structure extending upward away from one end of the feeding chute 41, and the blanking notch 431 corresponds to the top of the upper conveying end of the infiltration roller 6;

[0041] See also Figure 1 、 Figure 2 The product 5 to be tested is transported from the loading chute 41 and the blocking channel 43 to the infiltration tank 1. The product 5 is blocked by the upward extension of the blocking channel 43 and falls downward from the drop notch 431 into the inner side of the upper conveying end of the infiltration rolling track 6.

[0042] After the product 5 to be tested falls into the penetration raceway 6, it rolls and conveys downward along the inclined surface of the penetration raceway 6. A turning cavity 102 is opened at the end of the penetration tank 1 close to the liquid draining tank 2. At the bottom end of the turning cavity 102, a plurality of filtrate raceways 10 corresponding to the position of the penetration raceway 6 are embedded and installed. The other end of the filtrate raceway 10 inclines downward and is fixed to the inner end wall of the liquid draining tank 2. The product 5 to be tested conveyed to the lower conveying end of the penetration raceway 6 is then transferred to the filtrate raceway 10 in the liquid draining tank 2 for liquid draining treatment;

[0043] A number of through holes are also opened on each end face of the filtrate raceway 10. The bottom height of the upper conveying end of the filtrate raceway 10 is higher than the top height of the upper conveying end of the penetration raceway 6. The inclination angle of the penetration raceway 6 is greater than the inclination angle of the filtrate raceway 10, and the inclined conveying length of the penetration raceway 6 is greater than the inclined conveying length of the filtrate raceway 10. The product 5 to be tested conveyed into the liquid draining tank 2 is conveyed downward along the inclined surface of the filtrate raceway 10 for liquid draining operation. The excess penetrant on the product 5 to be tested then falls into the liquid draining tank 2. The penetrant in the penetration tank 1 and the liquid draining tank 2 enters the filtering tank 3 for filtering together. The filtered penetrant is sprayed onto the product 5 to be tested initially entering the penetration tank 1 through the return pipe 11 and the spray head 111 to provide replenishment of the penetrant in the penetration tank 1;

[0044] The penetration tank 1, the liquid draining tank 2, and the filtering tank 3 are used in cooperation to form an overall modular penetration tank integrated structure. A filtering structure for filtering the treated penetrant is arranged inside the filtering tank 3 to realize the circulating filtration and flow of the penetrant. And a plurality of penetration raceways 6 arranged obliquely downward and completely immersed in the penetrant are arranged in the penetration tank 1 for the main penetration process. A number of through holes are opened on the end face of the penetration raceway 6. The internal width of the penetration raceway 6 is slightly larger than the thickness of the product 5 to be tested, and the internal height of the penetration raceway 6 is smaller than the inner radius size of the product 5 to be tested, so as to realize the smooth downward rolling of the product 5 to be tested along the internal inclined slideway of the penetration raceway 6. The penetrant in the penetration tank 1 crosses over the top of the penetration raceway 6, making the penetration raceway 6 completely immersed in the penetrant. The inclined raceway adopted is suitable for ring-shaped products, such as bearings and round tube products;

[0045] During the rolling process, the upper conveying end of the product 5 to be tested is always exposed above the penetration raceway 6. On the one hand, with the help of the inclined raceway, the penetration conveying can be realized without using any clamping structure to position the product 5 to be tested. On the other hand, during the continuous rolling and turning process, the effective full contact between each end face of the product 5 to be tested and the penetrant is realized, improving the penetration effect.

[0046] Example 2: On the basis of Example 1, please refer to Figure 4On the left and right sides of the infiltration tank 1, there are respectively installed the limit components 7 and the turning component 9 acting on the upper and lower ends of the infiltration roller 6, and the front and rear ends of the infiltration tank 1 close to the leachate tank 2 are fixed with electric push cylinders 8 for lifting and lowering the turning component 9. The electric push cylinder 8 and the turning component 9 cooperate to form a material operation structure, which is used to transfer the product to be tested 5 on the infiltration line. The details are as follows:

[0047] See also Figure 5 、 Figure 6 The limiting assembly 7 includes an arc-shaped limiting plate 71 rotatably mounted on the bottom wall of the upper conveying end of the infiltration roller 6. Side guide plates 72 movably embedded in the front and rear inner walls of the upper conveying end of the infiltration roller 6 are fixed on both the front and rear sides of the arc-shaped limiting plate 71. Multiple groups of adjacent side guide plates 72 and the edge side guide plates 72 are connected to the inner wall of the infiltration tank 1 through a rotating shaft 73, and a driving motor 1 is fixed on the outer end to rotate the rotating shaft 73.

[0048] See also Figures 9 - 10 , the turning assembly 9 includes a lifting seat 91 fixedly mounted on the telescopic end of a pair of electric push cylinders 8, a positioning plate 92 is fixed on the opposite end walls of the pair of lifting seats 91, a flip plate 93 is rotatably mounted between the pair of positioning plates 92, a plurality of material receiving structures corresponding to the positions of the infiltration roller 6 are fixed on the flip plate 93, and a linkage shaft is installed through the flip plate 93, and the two ends are respectively connected to the pair of positioning plates 92 for rotation. A driving motor 2 for rotating the linkage shaft is fixedly installed inside one of the lifting seats 91;

[0049] The material receiving structure includes an arc-shaped material receiving plate 94 fixed to the bottom end of the flip plate 93 and consistent with the internal width of the infiltration raceway 6. Side guide plates 95 arranged concentrically with the arc-shaped material receiving plate 94 are fixed on both sides of the upper end. The inner end face of the flip plate 93 is provided with an arc-shaped surface adapted to the structure of the side guide plates 95. The bottom wall of the lower conveying end of the infiltration raceway 6 is provided with a hollow groove 602 corresponding to the position of the arc-shaped material receiving plate 94. The end of the arc-shaped material receiving plate 94 away from the flip plate 93 is provided with an extension portion arranged upward along the inclined surface of the infiltration raceway 6 and embedded in the hollow groove 602.

[0050] See also Figures 5 - 10 The front and rear opposite inner walls of the upper and lower conveying ends of the infiltration roller 6 are provided with movable grooves for the side guide disc 1 72 and the side guide disc 2 95 to rotate, and the inner end surfaces of the side guide disc 1 72 and the side guide disc 2 95 are inclined downward and inward along the movable grooves, and the inner end surfaces of the side guide disc 1 72 and the side guide disc 2 95 are inclined;

[0051] That is, when the product 5 to be tested falls onto the conveying end of the permeation track 6, one end of the arc-shaped limiting plate 71 is fitted into the upper end of the arc-shaped rotating groove 601, and the other end of the arc-shaped limiting plate 71 extends upward. At this time, the maximum width position between the pair of side guide plates 72 faces upward, and the upper end of the arc-shaped limiting plate 71 is fitted into the upper end of the arc-shaped rotating groove 601. At this time, the upper end of the arc-shaped limiting plate 71 is flush with the inclined conveying surface of the permeation track 6, facilitating the product 5 to be tested to roll onto the arc-shaped limiting plate 71. The arc-shaped limiting plate 71 intercepts the product 5 to be tested. After the rotating shaft 73 rotates clockwise, the lower end of the arc-shaped limiting plate 71 is fitted into the lower end of the arc-shaped rotating groove 601. At this time, the lower end of the arc-shaped limiting plate 71 is flush with the inclined conveying surface of the permeation track 6, contacting and limiting the product 5 to be tested;

[0052] The setting of the limiting component 7 is used to play a role of timing material feeding for the product 5 to be tested conveyed from the feeding component 4 to the conveying end of the permeation track 6. Relying on the periodic repeated rotation of the limiting component 7, multiple products 5 to be tested are synchronously and periodically conveyed downward along the inclined conveying path of the permeation track 6.

[0053] Similarly, please refer to Figures 9 - 12 , when the product 5 to be tested rolls downward and approaches the material turning component 9, the maximum width position between the pair of side guide plates 95 faces upward, facilitating the product 5 to be tested to roll onto the arc-shaped receiving plate 94. When the product 5 to be tested completely rolls into the pair of side guide plates 95, the pair of arc-shaped receiving plates 94 with gradually decreasing inner end face width is conducive to guiding and limiting the product 5 to be tested, preventing the product 5 to be tested from tilting due to the excessive width after the pair of side guide plates 95;

[0054] Please refer to Figure 13 、 Figure 14 , in the subsequent upward lifting and turning actions, the pair of side guide plates 95 play a role of stable limiting for the product 5 to be tested. During the process of the pair of electric push cylinders 8 driving the material turning component 9 to lift upward, multiple groups of arc-shaped receiving plates 94 can rotate upward by a certain angle toward the extension part side to facilitate stably limiting the product 5 to be tested between the pair of side guide plates 95 and the arc-shaped receiving plates 94, preventing the product 5 to be tested from detaching. After the material turning component 9 is lifted to the material turning cavity 102;

[0055] At this time, by continuously driving the material turning component 9 to rotate by the driving motor II, multiple groups of arc-shaped receiving plates 94 are rotated clockwise outside the material turning cavity 102. At this time, the product 5 to be tested disengages from the side guide plates 95 and the arc-shaped receiving plates 94 downward and falls onto the conveying end of the filtrate track 10, and is conveyed downward along the inclined surface of the filtrate track 10 for the liquid draining operation.

[0056] In summary, the overall modular integrated structure of the permeation tank is composed of the permeation tank 1, the liquid drainage tank 2, and the filtration tank 3 in cooperation, realizing the circulating filtration and flow of the penetrant. Multiple permeation raceways 6 that are arranged obliquely downward and completely immersed in the penetrant are provided in the permeation tank 1 for the main permeation process. The inclined raceways are suitable for ring-shaped products such as bearings and round tube products. During the rolling process, the upper end of the product to be tested 5 is always exposed above the permeation raceway 6. On the one hand, with the help of the inclined raceway, long-distance conveying and permeation can be achieved without using any clamping structure to position the product to be tested 5. On the other hand, during the continuous rolling and turning process, full contact between each end face of the product to be tested 5 and the penetrant is effectively realized, improving the permeation effect.

[0057] In addition, by adding a material transfer structure in which an electric push cylinder 8 and a turning component 9 are cooperated at the lower conveying end of the permeation raceway 6, the product to be tested 5 after permeation is turned outward to the filtrate raceway 10, realizing an unobstructed permeation route of "directional inclined conveying, long-distance rolling permeation, and rolling and draining during operation".

[0058] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto; any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
