Description

Technical Field

[0001] This utility model relates to the field of earring sleeve processing technology, and in particular to a closing tool for earring sleeves. Background Technology

[0002] Earring sleeves are small accessories used to help wear earrings, typically made of metal, plastic, or other cylindrical materials. Their inner diameter matches the thickness of the earring post. When wearing an earring, the post is passed through the earlobe and inserted into the sleeve to secure it, preventing it from loosening or falling off. They come in various styles, colors, and materials to meet different fashion needs and are suitable for various earring types, including studs and hooks. They are practical for both everyday wear and special occasions, and can reduce irritation for those with sensitive ears. Earring sleeves are also finished with a tapered end during manufacturing.

[0003] The closing of an earring sleeve involves installing a bearing into the sleeve before closing it. Traditional closing methods require using steel balls or rollers to fix the sleeve circumferentially. This process not only extends the production cycle and increases costs but also affects the product's appearance quality, and positioning is difficult. Because the circumference of the earring sleeve's opening is difficult to position, it's challenging to meet dimensional requirements after closing through manual control alone. Furthermore, the shape of the closed portion cannot be guaranteed to be consistent, and cracking can occur at the closed area, making it unsuitable for production. Therefore, this art proposes a tooling for closing earring sleeves to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tooling for closing earring sleeves, which aims to improve the problem that the tooling used in the closing process of earring sleeves in the prior art is difficult to guarantee the closing quality and production cycle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for closing the earring sleeve, comprising: a lower mold for mounting on a workbench; an upper mold for cooperating with the lower mold; an earring sleeve body, which is the product to be processed; and a closing assembly for closing the earring sleeve body.

[0006] Furthermore, the lower mold is located directly below the upper mold and is bolted together, with the outer side of the earring sleeve body fitting against the outer side of the lower mold.

[0007] Furthermore, the closing assembly includes a power rod, an upper bushing, and a lower bushing. The power rod is disposed in the inner through hole of the upper mold, and the upper and lower bushings are sleeved on the outside of the power rod.

[0008] Furthermore, the upper bushing and the lower bushing are threaded together, and four positioning pins are equidistantly arranged at the bottom of the lower bushing.

[0009] Furthermore, the upper mold has four circular holes inside, and the positioning pin is slidably connected to the circular holes.

[0010] Furthermore, a nut is fitted onto the outside of the power rod, and the nut is located inside the upper bushing.

[0011] Furthermore, the power rod is externally fitted with bearing three, bearing one, and bearing two, with bearing three located inside the upper bushing.

[0012] Furthermore, bearing sleeves are provided on the outside of bearing one and bearing two, and the outer periphery of bearing one is in contact with the inner side of the upper bushing.

[0013] Furthermore, the bottom of the nut fits against the top of the bearing three, and scale lines are provided on the outer periphery of the upper bushing and the top of the lower bushing.

[0014] Furthermore, the bottom of the power rod fits into the top of the earring sleeve body, and a pin is provided inside the lower mold.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the earring sleeve body is installed into the tooling before closing, and the lower and upper molds are fixed with cylindrical pins. The closing is achieved by manually turning the power rod. When the power rod rotates to the corresponding position, the closing is completed. After closing, the corresponding line segment of the upper bushing can be recorded, which can ensure the size, improve efficiency and shorten the processing time. After closing, the power rod can be turned back to remove the finished product. The two cylindrical pins at the bearings play a positioning and protection role. The placement of these pins can prevent the head from deforming after closing. The tooling controls the closing size to ensure product consistency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of an earring sleeve closing fixture, mainly composed of a lower mold 1, an upper mold 2, an earring sleeve body 11 to be processed, and a closing assembly. The lower mold 1 serves as the base of the entire fixture, used to install on a workbench to provide stable support for other components. The upper mold 2 is located above the lower mold 1 and works in conjunction with the lower mold 1 to process the earring sleeve body 11. During processing, the earring sleeve body 11 is tightly fitted to the outer side of the lower mold 1 to ensure its accurate positioning. The closing assembly is the core part of this tooling, used to close the earring sleeve body 11. The closing assembly includes a power rod 3, an upper bushing 5, and a lower bushing 6. The power rod 3 is set in the inner through hole of the upper mold 2 and can rotate freely within the through hole. The upper bushing 5 and the lower bushing 6 are sleeved on the outside of the power rod 3 and are connected by threads. This connection method allows the upper bushing 5 and the lower bushing 6 to rotate relative to each other, thereby realizing the closing operation of the earring sleeve body 11. The bottom of the lower bushing 6 is equidistantly provided with four A positioning post 7 is provided. The upper mold 2 has four round holes inside, and the positioning post 7 slides through these holes to ensure the stability and accuracy of the lower bushing 6 during its up-and-down movement. A nut 4 is fitted onto the outside of the power rod 3, located inside the upper bushing 5, serving to fix and adjust the position of the upper bushing 5. Bearings 12 (third bearing), 8 (first bearing), and 9 (second bearing) are also fitted onto the outside of the power rod 3. Bearing 12 is located inside the upper bushing 5. Bearing sleeves 10 are fitted onto the outside of bearings 8 and 9, with the outer circumference of bearing 8 fitting against the inner side of the upper bushing 5. The upper bushing 5 is closed to ensure smooth rotation. The bottom of the nut 4 is in contact with the top of the bearing 12, further enhancing the stability of the entire structure. The outer periphery of the upper bushing 5 and the top of the lower bushing 6 are provided with scale lines. These scale lines can help the operator accurately control the degree of closing and ensure the dimensional accuracy of the earring sleeve body 11. The bottom of the power rod 3 is in contact with the top of the earring sleeve body 11 to provide power for the closing operation. The lower mold 1 is provided with a pin inside to fix the relative position of the lower mold 1 and the upper mold 2.

[0024] Specifically, before the closing operation, the earring sleeve body 11 is first installed into this fixture. Then, the lower mold 1 and the upper mold 2 are firmly fixed together using cylindrical pins to ensure the stability of the entire fixture during processing. Then, by manually turning the power rod 3, the rotation of the power rod 3 will drive the movement of related parts, thereby realizing the closing operation of the product. When the power rod 3 rotates to a specific corresponding angle, it indicates that the closing work of the earring sleeve body 11 is completed. Moreover, after the earring sleeve body 11 is closed, the corresponding line segments on the upper bushing 5 can be recorded. In this way, not only can the dimensions of the earring sleeve body 11 be accurately guaranteed, but the processing efficiency can also be greatly improved. To improve efficiency and shorten processing time, after the earring sleeve body 11 is finished, simply reverse the power rod 3 to easily remove it. A cylindrical pin is provided at the bearing 9 near the earring sleeve body 11. This cylindrical pin plays an important positioning role in this tooling and also protects the earring sleeve body 11. Placing the cylindrical pin at the bearing 9 effectively ensures that the head of the earring sleeve body 11 will not deform due to excessive force after the earring sleeve body 11 is finished. Ultimately, the finishing size of the earring sleeve body 11 is completely controlled by the tooling, thus effectively ensuring product consistency and ensuring that each processed earring sleeve has the same high-quality standard.

[0025] Working principle: Before closing, the earring sleeve body 11 is installed into this tooling and the lower mold 1 and upper mold 2 are fixed using a cylindrical pin. Then, the product is closed by manually turning the power rod 3. When the power rod 3 rotates to the corresponding angle, it means that the earring sleeve body 11 is closed. After the earring sleeve body 11 is closed, the corresponding line segment on the upper bushing 5 can also be recorded. This not only ensures the size of the earring sleeve body 11 but also improves processing efficiency and shortens processing time. After closing, the processed earring sleeve body 11 can be removed by reverse turning the power rod 3. A cylindrical pin is provided at the bearing 9 near the earring sleeve body 11. The cylindrical pin plays the role of positioning and protecting the earring sleeve body 11 in this tooling. Placing it at the bearing 9 ensures that the head of the earring sleeve body 11 will not deform due to excessive force after closing. The final closing size is completely controlled by the tooling, ensuring product consistency.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
