Description

Technical Field

[0001] The utility model belongs to fluorescence detection equipment, in particular to a fluorescence penetrant escaping device. Background Art

[0002] Fluorescent penetrant testing is an important method for efficient non-destructive testing of surface defects of materials and parts, which is widely used in the fields of aviation, aerospace, automobiles, ships, nuclear power, pressure vessels, machinery manufacturing, etc. This method is based on the characteristics of fluorescent substances under ultraviolet light, and can effectively locate and quantify surface defects without damaging the integrity of the object being tested.

[0003] The steps of fluorescent penetrant testing generally include: pretreatment, penetration, removal of excess penetrant, application of developer, drying and fluorescent detection. At present, the penetration process mainly immerses the workpiece to be tested in the penetrant tank for an appropriate time (usually several minutes to several tens of minutes) to allow the fluorescent penetrant to fully penetrate into the potential defects. Then the workpiece is taken out and suspended in the air, so that the excess fluorescent penetrant drips back into the penetrant tank. However, it takes a long time for the excess fluorescent penetrant to drip, resulting in a slow efficiency of the entire penetration process, which in turn affects the efficiency of the entire fluorescent detection.

[0030] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0031] See attached Figures 1 to 2 A fluorescent penetrant removal device includes: a collecting tank 100, a positioning support column 200, a hanging hanger 300 and a driving device 400.

[0032] A cylindrical accommodation space is formed inside the collecting tank 100, and accordingly, the hanging sling 300 is also a cylindrical frame structure. A discharge pipe 110 is provided at the bottom of the collecting tank 100, and the discharge pipe 110 is connected to the fluorescent penetration tank, and the fluorescent penetration liquid in the collecting tank 100 is returned to the fluorescent penetration tank through the discharge pipe 110. Preferably, a filtering device is provided on the discharge pipe 110 to prevent impurities from flowing back into the fluorescent penetration tank to ensure the quality of the fluorescent penetration liquid. In addition, a positioning support column 200 is provided at the bottom of the collecting tank 100 for installing the hanging sling 300.

[0033] The hanging sling 300 includes a frame 310, a connecting groove 320 installed on the top of the frame 310, a positioning groove 330 arranged at the bottom of the frame 310 and embedded on the positioning support column 200, and a placement rack 340 evenly distributed on the frame 310 and suitable for placing the parts to be inspected. Compared with the traditional hanging sling 300, the hanging sling 300 of the present application has a positioning groove 330 arranged at the bottom and a connecting groove 320 arranged at the top, so that the hanging sling 300 is rotatably installed in the collection tank 100.

[0034] The driving device 400 includes a mounting frame 410 fixedly mounted on the collecting tank 100, a rotating device 450 mounted on the mounting frame 410, and a rotating shaft 460 that is transmission-connected to the rotating device 450 and can be embedded in the connecting groove 320. The driving device 400 drives the hanging sling 300 and the workpiece 500 to be inspected to rotate, thereby realizing centrifugal dehydration, accelerating the separation of excess fluorescent penetrant, and thus improving the overall fluorescent detection efficiency. It should be noted that the centrifugal speed should not be too fast to ensure that the fluorescent penetrant that has penetrated into the interior of the part to be inspected will not deviate significantly in the lateral direction. Preferably, the centrifugal speed can be 300rpm / min to 1000rpm / min.

[0035] In a further embodiment, a steel mesh 350 is laid on the bottom and circumference of the frame 310 to prevent some parts to be inspected from falling out and causing unnecessary damage during the lifting and centrifugation process.

[0036] In a further embodiment, the driving device 400 further includes: a translation device 420, a lifting device 430, and a crossbeam 440. The translation device 420 is disposed on the mounting frame 410, and the moving direction of the translation device 420 is perpendicular to the moving direction of the transmission line of the hanging sling 300, and is used to adjust the position of the crossbeam 440. When placing or removing the hanging sling 300, the crossbeam 440 and the driving device 400 are moved to one end of the translation device 420 to make room for the operating space of the transmission device of the hanging sling 300, thereby avoiding interference between the driving device 400 and the hanging sling 300. The lifting device 430 is disposed on the output end of the translation device 420, and the cross-sections of the connecting groove 320 and the rotating shaft 460 are both polygonal structures of the same shape, see the attached figure. Figure 2 In this embodiment, the cross-sections of the connecting groove 320 and the rotating shaft 460 are both regular pentagons. The connecting groove 320 can be connected to the rotating shaft 460 by the lifting device 430, and no additional fixing device is required to fix the coupling composed of the rotating shaft 460 and the connecting groove 320. The connecting groove 320 and the rotating shaft 460 are transition fit or clearance fit, and the rotating shaft 460 and the connecting groove 320 can be separated by the lifting device 430. One end of the crossbeam 440 is installed on the output end of the lifting device 430 through a triangular truss, and the rotating device 450 and the rotating shaft 460 are installed at the other end of the crossbeam 440.

[0037] It should be noted that the translation device 420 and the lifting device 430 are both common linear motion modules, and the rotating device 450 can be a servo motor, and is connected to the rotation through a belt or a gear set, which are all existing technologies and will not be described in detail here.

[0038] In a further embodiment, a partition frame 120 is provided at the lower part of the collection tank 100, so that a predetermined gap is left between the bottom of the collection tank 100 and the hanging hanger 300, so as to facilitate the collection of the fluorescent penetrant. At the same time, the positioning support column 200 is installed on the partition frame 120. In order to improve the rotation effect between the support column and the hanging hanger 300, a bearing can be installed on the outside of the positioning support column 200 to ensure the smoothness of the rotation of the hanging hanger 300.

[0039] In order to facilitate understanding of the technical solution of the fluorescent penetrant removal device, a brief description of its working principle is given: after the penetration of the workpiece 500 to be inspected is completed, the hanging sling 300 is placed in the collection tank 100 through the transmission device, and the positioning groove 330 at the bottom of the hanging sling 300 is embedded and installed on the positioning support column 200, and then the rotating shaft 460 is moved to the top of the connecting groove 320 through the translation device 420, and then the rotating shaft 460 can be embedded in the connecting groove 320 through the lifting device 430 to achieve the connection between the rotating shaft 460 and the connecting groove 320. Then, the driving device 400 drives the hanging sling 300 and the workpiece 500 to be inspected to rotate, realize centrifugal dehydration, accelerate the separation of excess fluorescent penetrant, and thus improve the overall fluorescent detection efficiency. The fluorescent penetrant that has escaped flows back to the fluorescent penetrant tank through the discharge pipe 110.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
