Description

Technical Field

[0001] The utility model relates to an efficient cleaning device for threaded holes on metal parts, belonging to the technical field of metal processing. Background Art

[0002] Generally, several threaded holes for connection are provided on metal parts. During tapping, metal chips will remain in the holes. In addition, chemical conversion treatment is required after tapping, so that chemical conversion treatment liquid will remain in the holes. In order to avoid the influence of the remaining metal chips and chemical conversion treatment liquid on the connection effect of the threaded holes, it is necessary to clean the threaded holes to ensure that the inside of the threaded holes is clean and does not affect the connection effect.

[0003] At present, the main method is manual blowing, that is, the staff holds an air gun, aligns the air outlet of the air gun with the threaded holes on the metal part, and blows air through the air gun to each threaded hole on the metal part to blow out the metal chips and remaining chemical conversion treatment liquid in all threaded holes; for metal parts with multiple threaded holes (for example: there are usually dozens of threaded holes on an automotive display bracket), this blowing method will have problems such as low cleaning efficiency, easy to miss blowing, and difficult to clean thoroughly, thus affecting the industrial production efficiency and quality assurance of such metal parts; in addition, when cleaning the threaded holes by manual blowing, the metal chips in the threaded holes will splash everywhere in the workshop under the action of the air flow, which not only pollutes the workshop environment, but also easily causes safety risks, and it is also very difficult to completely clean the remaining chemical conversion treatment liquid in the threads by manual blowing.

[0050] In this embodiment, please also refer to Figure 1 and Figure 6 As shown, the diversion grooves 4-1 and the blowing needles 7 respectively correspond one-to-one to the threaded holes 6-1 on the metal part 6. The outlet ends of the blowing needles 7 are respectively located in the diversion grooves 4-1 at the corresponding positions, that is: the diversion grooves 4-1 and the blowing needles 7 respectively correspond one-to-one to the number and positions of the threaded holes 6-1. In this way, synchronous and precise cleaning of multiple threaded holes can be realized. The sewage formed by cleaning each threaded hole 6-1 flows into the sewage collection cavity 8 through the corresponding diversion groove 4-1, so as to play a better role in guiding the sewage, and can better prevent metal chips from splashing and environmental pollution.

[0051] The operation method of using the high-efficiency cleaning device described in the present invention to clean the threaded holes on the metal part is as follows:

[0052] In this embodiment, taking Figure 8 the automotive display bracket shown as an example, as Figure 8 can be seen, there are multiple threaded holes 6-1 that need to be cleaned on the metal part 6 of the automotive display bracket;

[0053] Please also refer to Figure 6As shown, turn the side of the metal part 6 with the threaded hole 6-1 downward, and then place the metal part 6 in the product placement area of the backing plate 4, and make the threaded holes 6-1 of the metal part 6 correspond to the blowing needles 7 one by one;

[0054] Connect the high-pressure water source (specifically: open the electromagnetic water valve 12 to connect the high-pressure water source). The high-pressure water enters the water and gas collecting cavity 5 through the pipeline, and then blows out from the blowing needle 7. The blown water discharges the metal chips and chemical conversion treatment liquid in the threaded hole 6-1 of the metal part 6. Then cut off the high-pressure water source (specifically: close the electromagnetic water valve 12 to cut off the high-pressure water source), and connect the high-pressure gas source. The high-pressure gas enters the water and gas collecting cavity 5 through the pipeline. The high-pressure gas first pressurizes the remaining water in the water and gas collecting cavity 5 and blows it out from the blowing needle 7. After all the water in the water and gas collecting cavity 5 is discharged by the high-pressure gas, the high-pressure gas continuously blows out from the blowing needle 7, so as to continuously blow air into the threaded holes 6-1 on the metal part 6 until the moisture in all the threaded holes 6-1 is dried, thus realizing the flushing and drying treatment of the threaded holes 6-1 on the metal part 6;

[0055] The sewage containing metal chips and chemical conversion treatment liquid generated during the cleaning process flows into the sewage collection cavity 8 through the diversion groove 4-1, and then flows into the sewage collection container through the pipeline from the sewage collection cavity 8 for centralized treatment and recycling;

[0056] After the cleaning is completed, remove the metal part 6.

[0057] As can be seen from the above, through the ingenious structural design of the present utility model, the threaded holes are flushed and dried by the cooperation of high-pressure gas and high-pressure water. It can not only thoroughly clean the residual metal chips and chemical conversion treatment liquid in the threaded holes on the metal part, but also simultaneously clean multiple threaded holes synchronously, with high cleaning efficiency and convenient operation; in addition, the sewage containing metal chips and chemical conversion treatment liquid generated during the cleaning process can be collected, having the advantages of environmental protection and safety; therefore, the present utility model has obvious practical value.

[0058] Finally, it is necessary to point out here that: the above description is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
