[0002] Gold jewelry is jewelry made of gold. Gold is a precious metal and one of the earliest metals discovered and developed by humans. It is an important raw material for making jewelry and coins, and an important national reserve material. It is not only regarded as a symbol of beauty and wealth, but also benefits human life with its unique value.

[0003] A Chinese patent with publication number CN216608424U was searched and it was found that a polishing device with good sealing performance for gold jewelry was disclosed.

[0004] The above technical solution includes a fixed base, a side mounting plate and a mounting tube. The left outer end of the fixed base is rotatably connected with an adjustment buckle, and a notch is provided at the lower left end of the adjustment buckle. The side mounting plate is snap-connected to the left outer end of the fixed base, and a fixing rod is fixedly connected to the lower outer end of the side mounting plate. A driving motor is provided at the left inner end of the fixed base, and a groove is provided in the middle of the upper end of the fixed base, and driven wheels are provided on the outer sides of the four corners of the groove. The gold jewelry polishing device with good sealing performance is provided with a driven wheel. When the mounting tube rotates, the outer hoop on the outer side of the retaining edge fits the surface of the driven wheel. On the one hand, it is supported by the driven wheel, and on the other hand, the rotation of the driven wheel realizes the contact with the entire mounting tube and converts it into rolling friction, thereby reducing wear and consumption to improve the rotation stability of the mounting tube and ensure the stability of the polishing and grinding inside the entire mounting tube.

[0025] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0026] Example 1

[0027] See also Figure 1 to Figure 2Embodiment 1 is described, including a processing component 10, which is arranged on a base 23, and the base 23 plays a supporting role. The processing component 10 includes a half-stroke toothed plate 13, and a stroke gear 17 is meshed on one side of the half-stroke toothed plate 13. The half-stroke toothed plate 13 drives the stroke gear 17 to rotate. The stroke of the stroke gear 17 is twice that of the half-stroke toothed plate 13. A single stroke of the half-stroke toothed plate causes the stroke gear 17 to rotate 180°, thereby realizing the conversion of the grinding piece 22 and the punching piece 21. The lower end of the stroke gear 17 is rotatably connected to the support plate 16, and the support plate 16 plays a supporting and positioning role. The upper end of the stroke gear 17 is fixedly connected to a telescopic column 19 through a connecting shaft 18, and the upper end of the telescopic column 19 is fixedly connected to a mounting plate 20. The mounting plate 20 is used to install equipment. It should be noted that the movement of the grinding piece 22 or the punching piece 21 can be moved by setting a double-axis linkage mechanism on the mounting plate 20, but This is not the key point of the present device and will not be elaborated here. A punching member 21 is fixedly connected to one side of the mounting plate 20, and the punching member 21 performs a punching operation. A grinding member 22 is fixedly connected to the other side of the mounting plate 20, and the grinding member 22 performs a grinding operation. A push rod 12 is fixedly connected to one side of the half-stroke toothed plate, and the push rod 12 is movably connected to the output end of the push cylinder 11. The push cylinder 11 pushes the push rod 12, and the push rod 12 pushes the half-stroke toothed plate 13 to move. A slider 14 is fixedly connected to the lower end of the half-stroke toothed plate, and the slider 14 is slidably connected in the slide rail 15. The setting of the slider 14 and the slide rail 15 supports the half-stroke toothed plate 13. The length of the slide rail 15 is twice that of the half-stroke toothed plate 13. The distance moved by the half-stroke toothed plate 13 to the end of the slide rail 15 satisfies the rotation of the travel gear 17 by 180°, that is, the movable distance of the half-stroke toothed plate 13 in the slide rail 15 is equivalent to half the stroke of the travel gear 17.

[0028] In this embodiment, the push cylinder 11 pushes the push rod 12, and the push rod 12 pushes the half-stroke gear plate 13 to move the half-stroke gear plate to drive the travel gear 17 to rotate. Under the restriction of the slide rail 15, the single stroke of the half-stroke gear plate causes the travel gear 17 to rotate 180°. The rotation of the travel gear 17 drives the telescopic column 19 to rotate, and the rotation of the telescopic column 19 drives the mounting plate 20 to rotate. The rotation of the mounting plate 20 causes the grinding part 22 and the punching part 21 to interchange positions, completing the conversion between the grinding process and the punching process, enriching the functionality of the device and having strong competitiveness.
