Description

Technical Field

[0001] This utility model relates to a flaw detection mechanism, and more particularly to a fluorescent penetrant flaw detection line, belonging to the field of flaw detection technology. Background Technology

[0002] Currently, in the process of fluorescent penetrant testing, a penetrant containing fluorescent dye is first evenly coated on the surface of the workpiece. After it has fully penetrated into the defect, the excess penetrant that has not penetrated into the defect is removed from the surface of the workpiece. Then, a developer is applied to the surface of the workpiece. Finally, the workpiece is placed in a dark room and irradiated with an ultraviolet lamp to complete the defect inspection.

[0003] However, when using the natural penetration method, the penetration time is relatively long, which will prolong the detection cycle; and during the process of spraying the penetrant and developer, the two are easy to splash to other parts, which will make the cleaning work more difficult.

[0004] To address these issues, a fluorescent penetrant testing line was designed. Utility Model Content

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a fluorescent penetrant testing line, including a base 1, and a vibration table 2 is provided at the middle position of the top of the base 1. The base 1 serves as an overall support structure, and the vibration table 2 at the middle of the top is used to place the workpiece to be tested, providing a bearing foundation for subsequent penetrant, development and other operations.

[0036] A U-shaped frame 6 is slidably arranged between the two sides of the top of the base 1 along the length direction. A spraying mechanism 7 is installed on the U-shaped frame 6. The U-shaped frames 6 on both sides of the base 1 can slide along the length direction, and the spraying mechanism 7 mounted on them can move with the U-shaped frame 6 to realize the spraying of penetrant and developer on the workpiece on the vibration table 2.

[0037] An ultraviolet lamp 8 is installed at the middle position of the bottom of the U-shaped frame 6. After the developer is sprayed, the workpiece is irradiated by ultraviolet light. In a dark room environment, the fluorescent penetrant that has penetrated into the defects emits fluorescence, thereby revealing the defects on the surface and near the surface of the workpiece and completing the inspection.

[0038] Example 2

[0039] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0040] like Figure 1 As shown, in a preferred embodiment, based on the above method, the base 1 has strip grooves 101 on both sides of the top along the length direction. Sliding blocks 102 are slidably arranged inside the strip grooves 101. The two ends of the bottom of the U-shaped frame 6 are respectively fixed on the sliding blocks 102. The U-shaped frame 6 can slide stably along the length direction of the strip grooves 101 to avoid deviation. This structure ensures that the spraying mechanism 7 and the ultraviolet lamp 8 can be accurately aligned with the workpiece on the vibration table 2, ensuring the accuracy of the spraying and inspection positions.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, a handle is further provided at the middle position of the top of the U-shaped frame 6. The handle at the top of the U-shaped frame 6 allows the operator to manually push the U-shaped frame 6 and flexibly adjust its position to adapt to the testing needs of workpieces of different sizes. A collection basket 9 is fixed at one end of the base 1 to collect excess penetrant, developer waste liquid or waste material generated during the testing process, so as to avoid polluting the working environment and simplify the subsequent cleaning process.

[0042] like Figure 2As shown, in a preferred embodiment, based on the above method, the vibration table 2 further includes a carrier plate 201, springs 202, limiting posts 203, a vibration motor 204, and an outer protective frame 205. The carrier plate 201 is horizontally arranged on the top of the base 1. Springs 202 are provided between the four corners of the bottom of the carrier plate 201 and the base 1. The inner bottom of each spring 202 is provided with a limiting post 203 fixed to the top of the base 1. The vibration motor 204 is installed at the bottom of the carrier plate 201. The vibration motor 204 is model YZU-5-2, rated power (50-100W), vibration frequency range (30-60Hz), and amplitude (0.5-2mm).

[0043] An outer protective frame 205 is fixed to the outer side of the top of the base 1. The outer protective frame 205 is located on the outer side of the carrier plate 201, and the height of the outer protective frame 205 is 10-15mm higher than the upper surface of the carrier plate 201.

[0044] After the workpiece is placed on the carrier plate 201, the vibration motor 204 starts, causing the carrier plate 201 to vibrate. The spring 202 buffers the vibration, and the limit post 203 prevents the carrier plate 201 from displacing excessively. Vibration promotes the rapid penetration of the penetrant into the defects of the workpiece, solving the problem of long natural penetration time.

[0045] like Figure 1 As shown, in a preferred embodiment, based on the above method, a rectangular frame 3 is further fixed to the top of the carrier plate 201, and a cover plate 5 is hinged to one end of the rectangular frame 3. The rectangular frame 3 and the cover plate 5 can form a sealed space to prevent external factors from interfering with the penetration of the penetrant into the workpiece. In addition, the presence of the rectangular frame 3 can prevent splashing during spraying.

[0046] like Figure 1 As shown, in a preferred embodiment, based on the above method, the bottom of the cover plate 5 is provided with a heating wire 301, and the end of the cover plate 5 is provided with a temperature control switch 302. The temperature adjustment range of the temperature control switch 302 is 30-60℃, the optimal activity temperature of the penetrant is usually 40-50℃, the temperature control accuracy is (±2℃), the penetration time can be shortened to 1 / 3 of the natural penetration at 40℃, and shortened to 1 / 4 at 50℃, but it must not exceed 60℃ to prevent the penetrant from evaporating and becoming ineffective;

[0047] A storage battery 4 is provided on the side of the rectangular frame 3. The storage battery 4 is electrically connected to the heating wire 301, the temperature control switch 302, and the vibration motor 204 through wires.

[0048] After the penetrant is sprayed, when the workpiece is placed inside the sealed space, the temperature control switch 302 conducts electricity to the heating wire 301, and the activity of the penetrant is further accelerated by heating, thus shortening the penetration time.

[0049] like Figure 4As shown, in a preferred embodiment, based on the above method, the spraying mechanism 7 further includes a penetrant spray can 701, a developer spray can 702, a guide groove 703, a mounting block 704, and a nozzle 705. The penetrant spray can 701 is fixed to one end of the U-shaped frame 6, and the developer spray can 702 is fixed to the other end of the U-shaped frame 6. A guide groove 703 is provided along the length direction at the middle position of the top of the U-shaped frame 6. Mounting blocks 704 are slidably arranged at both ends inside the guide groove 703. A nozzle 705 is installed at the bottom of each mounting block 704. The nozzle 705 is an atomizing nozzle with an atomization angle of 60°. The penetrant spray can 701 and the developer spray can 702 are respectively connected to the two sets of nozzles 705 through pipes, and a solenoid valve is provided on the pipes.

[0050] During the spraying process, push the U-shaped frame 6 to the appropriate position, slide the mounting block 704 to adjust the position of the penetrant nozzle 705, keep the penetrant spray can 701 and the developer spray can 702 under high pressure, open the corresponding solenoid valve, and spray the penetrant and developer onto the workpiece.

[0051] Example 3

[0052] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0053] During inspection, open the cover plate 5, place the workpiece on the carrier plate 201 inside the rectangular frame 3, push the U-shaped frame 6 to the appropriate position, adjust the position of the penetrant nozzle 705 by sliding the mounting block 704, open the corresponding solenoid valve, and spray the penetrant onto the workpiece. The rectangular frame 3 blocks splashes. After spraying, close the cover plate 5, start the vibration motor 204 to vibrate the carrier plate 201, and at the same time start the heating wire 301 through the temperature control switch 302. Under the dual action, the penetrant quickly penetrates into the defect. After penetration is complete, clean the excess penetrant on the workpiece surface that has not penetrated into the defect, adjust the position of the developer nozzle 705, and spray the developer. The developer absorbs the penetrant in the defect and forms a display mark on the surface. Move the U-shaped frame 6 so that the ultraviolet lamp 8 at the bottom irradiates the workpiece. Observe the fluorescent display mark in the dark room to complete the defect identification. Waste can be put into the collection basket 9 for unified disposal.

[0054] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
