Description

Technical Field

[0001] This utility model relates to the field of brightness detection technology, specifically to an online monitoring device for detecting the brightness of a fluorescent penetrant. Background Technology

[0002] Penetrant testing is a non-destructive testing method that uses capillary action to inspect surface defects in materials. The process involves coating a penetrant containing dye or fluorescence onto the surface of a part. Under capillary action, the penetrant penetrates into the surface opening defects due to the wetting of the liquid and the capillary effect. After removing the excess penetrant from the surface of the part, a developer is applied. The penetrant in the defects is then re-adsorbed onto the surface of the part under capillary action, forming a magnified image of the defect.

[0003] The patent application number CN202320649124.7 mentions an "online monitoring fluorescent penetrant brightness detection device". This online monitoring fluorescent penetrant brightness detection device is easy to use and can improve the accuracy of brightness measurement of fluorescent penetrants. However, the above-mentioned device is only suitable for detection on a flat surface. For detection on curved surfaces, the brightness detection is easily inaccurate due to angle issues, resulting in low detection accuracy. In addition, the applicable range is small.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an online monitoring type fluorescent penetrant brightness detection device, comprising a monitoring frame, wherein a movable detection component is connected to the bottom end of the monitoring frame, and the movable detection component comprises a trapezoidal frame;

A rotating shaft is installed inside the shaft tube at the output shaft end of the moving motor. A moving wheel is fixedly sleeved in the middle of the rotating shaft. A through hole is opened on the bottom surface of the trapezoidal frame corresponding to the moving wheel.

[0007] Rubber plates are glued to both ends of the bottom surface of the trapezoidal frame. Roller sleeves are glued to the bottom ends of the rubber plates. The roller sleeves are rotatably sleeved on the middle of the roller rod. The roller rod is installed inside the deformable rail piece.

[0029] Example: Figure 1-4As shown, this utility model provides a technical solution for an online monitoring type fluorescent penetrant brightness detection device, including a monitoring frame 1, with a movable detection component 2 connected to the bottom end of the monitoring frame 1. The movable detection component 2 includes a trapezoidal frame 201, a shaft tube 202, a moving motor 203, a rotating shaft 204, a moving wheel 205, a wheel hole 206, a rubber plate 207, a roller sleeve tube 208, a roller rod 209, a deformable rail 210, a deformable rubber rail 211, and an anti-slip outer ring 212.

[0030] The bottom end of the monitoring frame 1 is welded to the middle of the top surface of the trapezoidal frame 201. A shaft tube 202 is fixedly installed in the middle of the bottom surface of the trapezoidal frame 201. A moving motor 203 is fixedly installed at one end of the shaft tube 202. A rotating shaft 204 is installed inside the shaft tube 202 at the output shaft end of the moving motor 203. The input end of the moving motor 203 is electrically connected to the output end of an external power supply. The width of the bottom surface of the trapezoidal frame 201 is smaller than the length of the shaft tube 202, which facilitates the rotation of the rotating shaft 204 inside the shaft tube 202 and ensures the normal operation of the moving motor 203. A moving wheel 205 is fixedly sleeved in the middle of the rotating shaft 204. A through hole 206 is opened on the bottom surface of the trapezoidal frame 201 corresponding to the moving wheel 205.

[0031] Rubber plates 207 are glued to both ends of the bottom surface of the trapezoidal frame 201. Roller sleeves 208 are glued to the bottom ends of the rubber plates 207. The roller sleeves 208 are rotatably sleeved on the middle of the roller rod 209. The roller rod 209 is installed inside the deformable track piece 210. The opposite faces of adjacent deformable track pieces 210 are respectively connected to the two ends of the deformable rubber rail 211. The end face of the roller sleeve 208 is C-shaped, and the inner side of the roller sleeve 208 is a smooth curved surface. The longitudinal cross-section shape and size of the deformable track piece 210 and the deformable rubber rail 211 are the same, which facilitates the rotation of the roller rod 209 inside the roller sleeve 208. An anti-slip outer ring 212 is glued to the outside of the moving wheel 205. Anti-slip grooves are evenly opened on the outside of the anti-slip outer ring 212, and the outside of the anti-slip outer ring 212 is attached to the inner side of the deformable track piece 210, which facilitates the rolling of the moving wheel 205 in the track formed by splicing the deformable track piece 210 and the deformable rubber rail 211.

[0032] The deformable rail pieces 210 located at both ends are connected to the fixed end assembly 3. The fixed end assembly 3 includes a spring plate 301, an internal threaded tube 302, a tensioning screw 303, a movable sleeve 304, a fixing piece 305, a fixing tube 306, a fixing pin 307, a limiting hole 308, a negative pressure blind tube 309, and a silicone soft ring 310.

[0033] A spring plate 301 is fixedly connected to one side of the deformable rail piece 210 at both ends. A threaded tube 302 is symmetrically welded to the end of the spring plate 301 away from the deformable rail piece 210. One end of the tensioning screw 303 is connected to the inside of the threaded tube 302 by a thread. The other end of the tensioning screw 303 is rotatably connected to the movable sleeve 304. The two movable sleeves 304 located on the same straight line are hinged to both ends of one side of the fixed piece 305. A fixed tube 306 is symmetrically welded to the top surface of the fixed piece 305. A fixing nail 307 is installed inside the fixed tube 306. A limiting hole 308 is opened in the middle of the fixed piece 305. A negative pressure blind tube 309 is embedded inside the limiting hole 308. A silicone soft ring 310 is glued to the bottom surface of the negative pressure blind tube 309. The bottom surface of the silicone soft ring 310 is flush with the bottom surface of the fixed piece 305, so as to facilitate the adsorption and detection position of the silicone soft ring 310.

[0034] The working principle and usage process of this utility model are as follows: When brightness monitoring is required, the track composed of the deformable rail plate 210 and the deformable rubber rail 211 is placed near the monitoring position. The fixing plates 305 at both ends are pulled. For short-term or temporary fixation, and if the mounting surface is smooth, a negative pressure blind tube 309 is embedded in the limiting hole 308. One end of the silicone soft ring 310 is attached to the mounting surface. Then, the negative pressure blind tube 309 is pressed, causing it to deform. The silicone soft ring 310 is then firmly adhered to the mounting position. For long-term installation and fixation, the aforementioned temporary fixation... After completion, rotate the tension screw 303 inside the movable sleeve 304. The tension screw 303 pulls the internal thread tube 302 inside the spring plate 301. The spring plate 301 moves closer to the fixing piece 305, and the spring plate 301 bends and better fits the installation position, making the deformable rail piece 210 and deformable rubber rail 211 better fit the installation surface. Finally, press the fixing nail 307 inside the fixing tube 306. The fixing nail 307 is driven into the installation position, completing the installation operation. Whether it is a temporary installation or a long-term installation, it can be firmly fixed in the installation position, with good installation effect.

[0035] The deformable rail piece 210 and the deformable rubber rail 211 will change with the curvature of the installation position. The deformable rubber rail 211 will deform so that the deformable rail piece 210 fits the curved surface of the installation. A roller 209 is installed in the track formed by the combination of the deformable rail piece 210 and the deformable rubber rail 211. The roller sleeve 208 is snapped onto the outside of the roller 209. At this time, the moving wheel 205 is in the track formed by the combination of the deformable rail piece 210 and the deformable rubber rail 211. The anti-slip outer ring 212 contacts the inner bottom surface, and the rubber plate 207 will deform with the curvature of the deformable rail piece 210 and the deformable rubber rail 211, making it more adaptable.

[0036] When the moving motor 203 is started, the rotating shaft 204 inside the shaft tube 202 drives the moving wheel 205 to rotate, changing the position of the monitoring frame 1. The device for detecting brightness is the same as the detection device in the patent application number 202320649124.7. The detection principle will not be described in detail. When brightness needs to be monitored, the monitoring frame 1 moves at a constant speed in the track formed by the combination of the deformable rail plate 210 and the deformable rubber rail 211, so that the detection instrument of the monitoring frame 1 is always facing the detection, avoiding the problem of inaccurate brightness monitoring due to the angle position of the monitoring.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
