Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning tool for cleaning micro blind holes. Background Art

[0002] In the context of the rapid development of modern precision manufacturing and micro-nano technology, parts with micro blind hole structures are widely used in high-tech fields such as electronic devices, medical devices, and aerospace. The micro blind holes on these parts, due to their tiny apertures and complex structures, pose unprecedented challenges to the cleaning work. Traditional cleaning methods, such as manual wiping and high-pressure liquid flushing, often have difficulty reaching and effectively removing pollutants such as tiny particles, grease, and residues inside the holes, directly affecting the performance and lifespan of the products.

[0003] Ultrasonic cleaning technology, with its advantages of high efficiency, environmental protection, and non-contact cleaning, stands out among many cleaning methods. By utilizing the cavitation effect and acceleration effect of ultrasonic waves in the cleaning liquid, it can penetrate into fine gaps, break down and peel off the dirt attached to the object surface, and achieve deep cleaning. However, when facing parts with micro blind holes, due to the special structure of the blind holes, bubbles are prone to accumulate at the hole openings and form a barrier, hindering the effective penetration of the cleaning liquid and resulting in ineffective cleaning of the inner area of the holes. Summary of the Invention

[0004] To solve the above problems, the present application provides a cleaning tool for cleaning micro blind holes, which is provided with a support cavity. A top plate is arranged above the support cavity. A liquid inlet is arranged on the support cavity. A part cleaning unit is arranged on the support cavity. The part cleaning unit is provided with a liquid outlet pipe, and the liquid outlet pipe is communicated with the support cavity. Support fins are arranged on the side wall of the liquid outlet pipe.

[0005] In one embodiment, there are at least two support fins, and the support fins are spaced at the same angle.

[0006] In one embodiment, a liquid return groove is arranged on the liquid outlet pipe.

[0007] In one embodiment, a top plate positioning hole is arranged on the top plate, and the top plate is locked to the support cavity through a bolt assembly.

[0008] In one embodiment, the support cavity includes a support frame and a support plate. The support plate is detachably installed on the support frame. The cleaning tool is further provided with a part mounting plate that cooperates with the support plate. A part placement cavity is arranged on the part mounting plate, and the part placement cavity is arranged opposite to the part cleaning unit.

[0009] In one embodiment, there are three support fins, and the adjacent support fins are spaced 120°.

[0010] In one embodiment, a positioning hole is provided on the support plate, and a positioning hole is provided on the part mounting plate.

[0011] The beneficial effects of the present utility model are as follows:

[0012] A cleaning tool for cleaning micro blind holes in this application is provided with a support cavity. A top plate is provided above the support cavity. A liquid inlet is provided on the support cavity. A liquid outlet pipe is provided on the support cavity. The liquid outlet pipe is communicated with the support cavity. Support fins are provided on the side wall of the liquid outlet pipe. The part to be cleaned is installed on the liquid outlet pipe. Under the pressure of the circulation pump, the cleaning liquid is sprayed into the blind hole of the part through the liquid outlet pipe. When the cleaning liquid sprays out from the liquid outlet pipe, a water flow with a flushing force is formed, which directly acts on the inside of the blind hole of the part. Through the direct spraying method, the dirt, grease and residues in the blind hole can be effectively dispersed and removed. Since the cleaning tool is completely immersed in the water tank of the ultrasonic cleaning machine, the ultrasonic wave can directly act on the surface of the part and the inside of the blind hole. The sprayed cleaning liquid can directly wash the dirt and impurities in the blind hole of the part and disperse the bubbles, breaking the bubble barrier to ensure the effective penetration of the cleaning liquid and the cleaning effect. Ultrasonic cleaning can penetrate into the fine parts of the blind hole, and use the cavitation effect and acceleration effect to disperse, emulsify and peel off the dirt layer, realizing the dual functions of liquid jet flushing and ultrasonic cleaning, and significantly improving the cleaning efficiency and quality.

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0031] As Figures 1-5 shown, a cleaning tool for cleaning micro blind holes is provided with a support cavity 1, a top plate 2 is arranged above the support cavity 1, a liquid inlet 11 is arranged on the support cavity 1, a part cleaning unit 3 is arranged on the support cavity 1, the part cleaning unit 3 is provided with a liquid outlet pipe 31, the liquid outlet pipe 31 is communicated with the support cavity 1, and a support fin 32 is arranged on the side wall of the liquid outlet pipe 31.

[0032] Specifically, the support cavity 1 is a hollow structure for containing and distributing cleaning liquid. The top plate 2 is located above the support cavity 1 and plays a role of limiting and stabilizing. The parts cleaning unit 3 includes a liquid outlet pipe 31 and a supporting fin 32. The liquid outlet pipe 31 is connected to the support cavity 1 and is used to transport the cleaning liquid to the blind hole of the part, while the supporting fin 32 is used to support the part to facilitate the reflux of the cleaning liquid. When in use, the part to be cleaned is first installed on the liquid outlet pipe 31, ensuring that the liquid outlet pipe 31 is inserted into the blind hole of the part, the bottom of the part is in contact with the supporting fin 32, the top is in contact with the top plate 2, and the liquid inlet 11 is connected to the liquid inlet pipe. After installation, the entire cleaning tool is completely immersed in the water tank of the ultrasonic cleaning machine, and the external circulation pump is started. The cleaning liquid is sucked in and enters the support cavity 1 through the liquid inlet 11. Under the pressure of the circulation pump, the cleaning liquid is then sprayed into the blind hole of the part through the liquid outlet pipe 31. When the cleaning liquid is sprayed out from the liquid outlet pipe 31, a water flow with flushing force is formed, which directly acts on the inside of the blind hole of the part. The direct spraying method can effectively disperse and remove the dirt, grease and residue in the blind hole. By setting the top plate 2, the parts can remain stable during the cleaning process to prevent movement or falling off due to the impact of the water flow. The supporting fins 32 promote the reflux of the cleaning liquid. Since the cleaning tool is completely immersed in the water tank of the ultrasonic cleaning machine, the ultrasonic wave can directly act on the surface of the part and the inside of the blind hole. The cavitation effect and acceleration effect generated by the ultrasonic wave in the liquid work together to disperse, emulsify and peel off the dirt layer. The dual effects of ultrasonic cleaning and liquid jet flushing complement each other, making the cleaning effect more significant. The sprayed cleaning liquid can directly flush away the dirt and impurities in the blind holes of the parts, disperse the bubbles, break the bubble barrier, and ensure the effective penetration of the cleaning liquid and the cleaning effect. Ultrasonic cleaning can penetrate deep into the tiny parts of the blind holes, and use the cavitation effect and acceleration effect to disperse, emulsify and peel off the dirt layer, thus achieving the dual effects of liquid jet flushing and ultrasonic cleaning. This dual cleaning method significantly improves the cleaning efficiency and quality.

[0033] like Figure 3 As shown, there are at least two supporting fins 32 , and the supporting fins 32 are spaced at the same angle.

[0034] Specifically, a plurality of support fins 32 are distributed on the side wall of the liquid outlet pipe 31 at the same angle intervals, providing more uniform and stable support for the parts installed on the liquid outlet pipe, reducing the shaking of the parts caused by water flow impact or ultrasonic vibration during the cleaning process, and improving the stability and reliability of cleaning. The intervals between the support fins 32 promote the reflux of the cleaning liquid. In this embodiment, there are three support fins 32, and the intervals between adjacent support fins 32 are 120°.

[0035] like Figure 3 As shown, a liquid return groove 311 is provided on the liquid outlet pipe 31 .

[0036] Specifically, when the cleaning liquid flows out of the blind hole of the part, it will naturally flow back along the liquid return groove 311, which helps to ensure that the cleaning liquid can fully cover and clean every corner of the blind hole, reducing the waste and splashing of the cleaning liquid. When the cleaning liquid is sprayed into the blind hole through the liquid outlet pipe 31, part of the liquid will flow along the inner wall of the blind hole and carry away the dirt, ensuring that the cleaning liquid can continuously and effectively clean the inside of the blind hole and improving the cleaning effect.

[0037] As Figure 2 shown, the top plate 2 is provided with a top plate positioning hole 21, and the top plate 2 is locked to the support cavity 1 through a bolt assembly.

[0038] Specifically, the combination of the top plate positioning hole 21 and the bolt assembly makes the connection between the top plate 2 and the support cavity 1 more firm and stable, capable of effectively resisting the vibration and impact force generated during the cleaning process, ensuring that the entire cleaning tool maintains a stable structural form during use, thereby improving the reliability of cleaning. The installation and disassembly through the bolt assembly make the replacement and maintenance of the top plate 2 more convenient and fast. When different types of parts need to be cleaned or tool maintenance is required, the bolt assembly can be easily loosened, and the top plate 2 can be removed from the support cavity 1, improving the flexibility and maintainability of the cleaning tool.

[0039] As Figure 2 、 6 shown, the support cavity 1 includes a support frame 12 and a support plate 13. The support plate 13 is detachably installed on the support frame 12. The cleaning tool is also provided with a part mounting plate 4 that cooperates with the support plate 13. The part mounting plate 4 is provided with a part placement cavity 41, and the part placement cavity 41 is arranged opposite to the part cleaning unit 3.

[0040] Specifically, first, the part to be cleaned is placed in the part placement cavity 41 of the part mounting plate 4 with the blind hole facing upward for subsequent docking with the liquid outlet pipe 31 on the support plate 13. Since the part has been pre-placed in the part placement cavity 41 and the blind hole is facing upward, the liquid outlet pipe 31 can accurately dock with the blind hole of the part. After the docking of the liquid outlet pipe 31 and the part is completed, the entire part mounting plate 4 is turned over, and the part is automatically mounted on the liquid outlet pipe 31 as the mounting plate is turned over. The batch installation method avoids the cumbersome steps of individually mounting the parts onto the liquid outlet pipe, improves the installation efficiency, and reduces the risk of adjacent parts being knocked down when directly mounting the parts onto the liquid outlet pipe 31.

[0041] As Figure 2 shown, the support plate 13 is provided with a support plate positioning hole 131, and the part mounting plate 4 is provided with a mounting plate positioning hole 42.

[0042] Specifically, by setting the mounting plate positioning holes 42 and the support plate positioning holes 131, it is convenient for the precise docking of parts, enabling the liquid outlet pipe 31 on the support plate 13 to be easily inserted into the blind holes of various parts on the part mounting plate 4 without worrying about position deviation or incorrect angle. By setting the support plate positioning holes 131, it is also convenient to lock the support plate 13 to the support frame 12.

[0043] A cleaning tool for cleaning micro blind holes in this application is provided with a support cavity 1. Above the support cavity 1, there is a top plate 2. On the support cavity 1, there is a liquid inlet 11. On the support cavity 1, there is a liquid outlet pipe 31, and the liquid outlet pipe 31 is connected and communicated with the support cavity 1. On the side wall of the liquid outlet pipe 31, there are support fins 32. The part to be cleaned is installed on the liquid outlet pipe 31. Under the pressure of the circulating pump, the cleaning liquid is sprayed into the part blind hole through the liquid outlet pipe 31. When the cleaning liquid sprays out from the liquid outlet pipe 31, a water flow with a flushing force is formed, directly acting on the inside of the part blind hole. Through the direct spraying method, it can effectively disperse and remove the dirt, grease, and residues in the blind hole. Since the cleaning tool is completely immersed in the water tank of the ultrasonic cleaning machine, the ultrasonic wave can directly act on the surface of the part and the inside of the blind hole. The sprayed cleaning liquid can directly wash the dirt and impurities in the part blind hole and disperse the bubbles, breaking the bubble barrier to ensure the effective penetration of the cleaning liquid and the cleaning effect. The ultrasonic cleaning can penetrate into the fine parts of the blind hole, and by using the cavitation effect and acceleration effect, the dirt layer can be dispersed, emulsified, and peeled off, realizing the dual effects of liquid jet flushing and ultrasonic cleaning, significantly improving the cleaning efficiency and quality.
