[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figures 1 to 4 As shown, the threaded hole foreign body cleaning device includes a base with a high-pressure inner cavity, at least one air inlet interface 3 is arranged on the base, the air inlet interface 3 is connected to the high-pressure inner cavity, a loading area is provided on the top surface of the base, a positioning component is arranged in the loading area, a material blocking component is arranged on the periphery of the loading area, and a plurality of air nozzles 4 are also arranged in the loading area, and the plurality of air nozzles 4 are connected to the high-pressure inner cavity.

[0030] like Figure 1 , 3As shown in Figures 4 and 5, the base includes a bottom plate 1 and a carrier plate 2 stacked from bottom to top, and the carrier plate 2 and the bottom plate 1 are sealed up and down to form a high-pressure inner cavity. The bottom plate 1 is specifically made of bakelite, and the carrier plate 2 is specifically made of AL6061 aluminum plate. The bottom plate 1 is concave downward from the top surface to form a lower groove cavity, and the carrier plate 2 is covered on the lower groove cavity by the bottom surface and is tightly attached to the edge of the lower groove cavity to form a sealed inner cavity environment, that is, a high-pressure inner cavity.

[0031] like Figure 1 , 2 As shown in Figures 4 and 5, at least one inlet is provided on the side wall of the bottom plate 1, and the inlet is connected to the air inlet interface 3, which is connected to the side of the lower tank cavity. Specifically, two air inlet interfaces 3 are arranged side by side on one side of the bottom plate 1, and the inner diameter of the air inlet interface 3 is 8 cm. The air inlet interface 3 is connected to the high-pressure pump through a gas hose. When the high-pressure pump is started, the high-pressure gas enters the high-pressure inner cavity through the gas hose and the air inlet interface 3, and the high-pressure gas is compressed and then expanded in the high-pressure inner cavity.

[0032] The center of the air jet nozzle 4 is provided with an air flow hole, the bottom of which is provided on the bottom surface of the carrier plate 2, and the air flow hole is connected to the lower groove cavity. The diameter of the air flow hole is 0.8 cm. The high-pressure gas compressed and expanded in the high-pressure inner cavity is blown out from each air flow hole to form a high-pressure flushing air flow.

[0033] The ratio of the inner diameter of the air inlet interface 3 to the diameter of the air flow hole is 10:1.

[0034] like Figure 1 , 3 As shown in FIG. 4 , the air nozzle 4 includes a cylindrical body, the top end of which is integrally connected to a conical body, and the cylindrical body is perpendicular to the top surface of the carrier plate 2. The conical body has a conical slope, and the diameter of the conical slope gradually increases from top to bottom, thereby forming a guide angle, which is conducive to the air nozzle 4 extending into the threaded hole of the product.

[0035] like Figures 1 to 4 As shown, the positioning assembly includes at least two positioning columns 5 and at least two support blocks 6 protruding from the top surface of the carrier plate 2. The height of the positioning column 5 is higher than that of the support block 6. The positioning column 5 and the support block 6 are both made of plastic material to prevent the product from being scratched when taking and placing the product. At least two positioning holes are set on the product. When the product is placed in the loading area, the positioning columns 5 are inserted into the positioning holes one by one to form a plane positioning to prevent the product from being misplaced or placed upside down. At the same time, the bottom surface of the product is supported by at least two support blocks 6 to improve the horizontality and stability of the product placement.

[0036] The material stopper assembly includes a plurality of profiling stoppers 1 and a plurality of profiling stoppers 2 protruding from the top surface of the carrier plate 2, wherein the profiling stopper 1 is a curved stopper 7 and the profiling stopper 2 is a straight stopper 8. The curved stopper 7 and the straight stopper 8 are both made of plastic material to prevent scratches on the product when taking and placing the product. When the product is placed in the material loading area, the curved stopper 7 is pressed against the corner of the product, and the straight stopper 8 is pressed against the straight edge of the product, thereby improving the accuracy and stability of product placement.

[0037] The working method of this threaded hole foreign body cleaning device is:

[0038] The product is placed in the loading area, and the positioning columns 5 are inserted into the positioning holes of the product one by one to form a plane positioning. At the same time, the bottom surface of the product is supported by at least two support blocks 6, and the curved stop block 7 is abutted against the corner of the product, and the straight stop block 8 is abutted against the straight edge of the product, so as to improve the accuracy and stability of product placement, and make the multiple air nozzles 4 extend into the multiple threaded holes of the product one by one.

[0039] The high-pressure pump is started to pass the high-pressure gas through the gas hose and the air inlet interface 3 into the high-pressure inner cavity, where the high-pressure gas is compressed and then expanded. Finally, the high-pressure gas is ejected at high speed and high pressure through the air flow holes of the plurality of air nozzles 4 to blow out the remaining foreign matter in the threaded hole.

[0040] Embodiment 2

[0041] This embodiment is basically the same as the first embodiment, except that:

[0042] At least one inlet is provided on the bottom wall of the bottom plate 1 , and the inlet is connected to an air inlet interface 3 , and the air inlet interface 3 is connected to the bottom of the lower tank cavity.

[0043] Specifically, an air inlet interface 3 is provided at the center of the bottom surface of the bottom plate 1. The air inlet placed at the center enables the high-pressure gas to flow into the high-pressure inner cavity more evenly, and thus the pressure of the high-pressure gas when it re-expands in the high-pressure inner cavity is more even.
