Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive testing, in particular to a fluorescent penetration testing device. Background Art

[0002] As one of the non-destructive testing technologies, fluorescent penetrant testing refers to a method in which a penetrant containing fluorescent substances is applied to the surface of the inspected part, penetrates into the surface defects through capillary action, and then the penetrant on the surface is cleaned off, and the penetrant in the defects is retained for imaging. In daily operation, it is generally necessary to clean the parts first, then spray the fluorescent liquid on the parts, and then clean them again, and then perform steps such as applying developer and ultraviolet irradiation. In this process, in order to improve efficiency, the parts are generally placed on a conveyor belt, and then the conveyor belt carries the parts through each process in turn for processing. When spraying the fluorescent liquid, since the height of the parts passing each time is different, multiple fluorescent liquid nozzles are generally set up to be distributed in a row and at a higher height, but the higher the height, the easier it is for the fluorescent liquid to splash when it drops on the parts.

[0003] The prior art discloses a fluorescent penetration detection device (publication number: CN211347989U), which includes a fluorescent liquid nozzle, a vertical seat and a cantilever. The vertical seat is provided with a cantilever, and the cantilever is provided with a fluorescent liquid nozzle. The cantilever is hollow and has left and right horizontally extending slideways on the front and rear side walls. An embedding opening is provided at the right end of the slide, and a plurality of embedded sliders are provided in the slide. The embedded sliders are embedded in the slide from the embedding opening and can move left and right along the slide. A threaded sleeve is provided at the end of the cantilever close to the vertical seat, and the threaded sleeve is driven up and down on the vertical seat by an electric height drive structure, so that the cantilever drives the fluorescent liquid nozzle to move up and down.

[0004] However, the above technical solution and the prior art still have the following defects: in order to ensure that the embedded slider will not be driven to move during the spraying process of the fluorescent liquid nozzle, a magnetic block is embedded in the part of the embedded slider that is in the cantilever, and the upper and lower ends of the magnetic block are magnetically adsorbed on the upper and lower walls of the inner cavity of the cantilever respectively, so that the magnetic adsorption effect of the magnetic block hinders the left and right movement of the embedded slider. However, due to the magnetic adsorption between the magnetic block and the inner wall of the cantilever, a certain friction force will be caused, which may cause the smooth movement of the slider to be hindered, increasing the difficulty of operation. At the same time, the force of the magnetic adsorption may affect the precise positioning and fine-tuning of the slider, making it difficult to adjust the position of the slider, thereby reducing the disassembly and assembly efficiency.

[0026] A fluorescent liquid spray head 12 is disposed on the cantilever 7 via a movable positioning assembly 11 . The movable positioning assembly 11 enables the fluorescent liquid spray head 12 to be detachably mounted on the cantilever 7 and ensures the stability of the fluorescent liquid spray head 12 .

[0027] An inner cavity 8 is provided inside the cantilever 7, side grooves 9 are symmetrically provided on both sides of the inner cavity 8, and a positioning groove 10 is provided at the center of the top of the inner cavity 8.

[0029] The movable positioning assembly 11 also includes a fastening screw block 114 disposed at the top of the stud 113. The interior of the fastening screw block 114 is threadedly connected to the top of the stud 113 to ensure the stability of the slider 111 embedded in the inner cavity 8, thereby ensuring the stability of the installation of the fluorescent liquid nozzle 12.

[0030] In this embodiment, by setting the cooperation between the movable positioning component 11 and the inner cavity 8, the side groove 9 and the positioning groove 10 on the cantilever 7, it is convenient to quickly disassemble and assemble the fluorescent liquid nozzle 12 on the movable positioning component 11, making the disassembly and assembly work more convenient and easy to operate, and improving the disassembly and assembly efficiency.

The operation is simple and convenient, and the stability is high.

[0031] Embodiment 2:

[0032] Based on the first embodiment, the lifting mechanism mentioned in the first embodiment is described as follows:

[0033] The lifting mechanism includes a servo motor 2, a screw rod 3, a sliding rod 4 and a movable slider 5. The servo motor 2 is arranged at the top of the support seat 1, and the output end of the servo motor 2 is connected and fixed to the connecting end of the screw rod 3 through a coupling. Sliding rods 4 are arranged on both sides of the screw rod 3, and the sliding rods 4 are fixedly installed on the support seat 1. The interior of the movable slider 5 is threadedly connected to the screw rod 3, and the interiors of both sides of the movable slider 5 are slidingly connected to the sliding rod 4. One side of the movable slider 5 is fixedly connected to one end of the cantilever 7. Sliding grooves 6 are opened on both sides of the movable slider 5, and the sliding grooves 6 are slidingly connected to the sliding rod 4.

[0034] A reinforcing rod 13 is provided at the bottom of the cantilever 7 , and two ends of the reinforcing rod 13 are respectively fixedly connected to the movable slider 5 and the center of the bottom of the other end of the cantilever 7 to reinforce the stability of the cantilever 7 .

[0035] In this embodiment, the cantilever 7 is set on the lifting mechanism, and the height of the fluorescent liquid nozzle 12 on the cantilever 7 is adjusted by the lifting mechanism. The fluorescent liquid nozzle 12 is adjusted to a suitable height to adapt to the height of the parts, reduce sputtering, and improve the spraying effect. The servo motor 2 is powered on to drive its output shaft to drive the screw 3 to rotate, so that the movable slider 5 moves up and down along the screw 3, thereby realizing the height adjustment of the fluorescent liquid nozzle 12 installed on the cantilever 7 on the movable slider 5.

[0036] Working principle: First, when installing the fluorescent liquid nozzle 12, the embedded slider 111 is directly slid along the inner cavity 8 at the opening at the other end of the cantilever 7 to the desired position, and then the fastening screw block 114 is tightened to achieve the overall stable installation, ensuring the stability of the fluorescent liquid nozzle 12. When disassembling, the movable positioning component 11 can be directly pulled out from the inner cavity 8 after loosening the fastening screw block 114. The operation is relatively convenient and the disassembly and assembly efficiency is improved. In order to improve the spraying effect of the fluorescent liquid, the lengths of the mounting side plates 112 for mounting the fluorescent liquid nozzle 12 on the multiple embedded sliders 111 on the same side of the cantilever 7 are different. In this way, when the parts pass through the fluorescent liquid nozzle 12 from front to back, the multiple fluorescent liquid nozzles 12 are at different positions on the left and right scales, and are also at different positions on the front and back scales, so that the fluorescent liquid sprayed by the fluorescent liquid nozzle 12 slides on the parts one after another, which can effectively improve the spraying effect of the fluorescent liquid, and is conducive to reducing the spraying amount of the fluorescent liquid and reducing costs.
