Description

Technical Field

[0001] The utility model relates to the technical field of coating fixtures, in particular to a fixing coating fixture for small-diameter ferrules. Background Art

[0002] In the field of manufacturing precision optical devices, ceramic ferrules have become ideal materials for key components such as fiber optic connectors due to their excellent physical and chemical properties, such as high hardness, wear resistance, corrosion resistance, and good thermal stability. Among them, ultra-fine ceramic ferrules with a diameter of only 1.25 mm have received special attention due to their important applications in miniaturized and high-performance communication networks. In order to further improve the performance of ceramic ferrules, such as improving their surface characteristics, enhancing their wear resistance and corrosion resistance, coating technology has become an indispensable part. However, when coating and processing ceramic ferrules with such a small size, especially when using conventional fixtures for batch production, a series of technical problems have been encountered.

[0003] In the design of traditional coating fixtures, such as a coating aluminum box disclosed in Patent CN201720632823.5, multiple jacks are usually arranged on a fixed plate to accommodate and position the ceramic ferrules to be coated. However, this structure exposes obvious deficiencies when dealing with ceramic ferrules with a diameter of only 1.25 mm: Lack of fixing flexibility: The jack design of conventional fixtures cannot provide sufficient fixing force and accuracy, making it difficult to adapt to the precise positioning of ceramic ferrules with such a small diameter, especially during the cleaning and coating processes.

[0004] Stability problems during the cleaning process: Since the cleaning agent has a lubricating effect, when the ceramic ferrules are placed on a conventional fixture for cleaning, they are extremely likely to slide and fall off, which not only affects the cleaning effect but also may cause damage to the ferrules, resulting in unnecessary cost losses.

[0005] Fixing difficulties during the coating process: Conventional fixtures cannot effectively fix ceramic ferrules for coating, making it difficult to ensure the uniformity and quality of the coating layer, seriously affecting the performance and production efficiency of the final product. Summary of the Invention

A first jack for fixing the ferrule is formed between adjacent side arc-shaped holes and middle arc-shaped holes. A second jack for fixing the ferrule is formed between adjacent middle arc-shaped holes.

[0008] Preferably, the fixing and coating jig for small-diameter ferrules is further provided with a rubber pad. The first locking member is arranged at one end of the ferrule fixing component. The rubber pad is arranged at the other end of the ferrule fixing component. The rubber pad is located between the ferrule fixing component and the side wall of the mounting hole.

[0009] Preferably, the rubber pad is provided with a positioning hole for assembling the fixing column.

[0010] Preferably, one end of the first locking member is screwed to the bottom plate, and the other end of the first locking member abuts against the ferrule fixing component.

[0011] Preferably, the fixing and coating jig for small-diameter ferrules further includes a second locking member. The second locking member is mounted on the bottom plate and is used to lock the fixing column.

Detailed implementation mode

[0031] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and drawings. The content mentioned in the implementation mode does not limit the present utility model. The present utility model will be described in detail below with reference to the drawings.

[0032] A fixing coating jig for small-diameter ferrules provided in this embodiment, as Figures 1 to 13 , includes a bottom plate 1, a plurality of ferrule fixing components 8, a plurality of first locking members 2, and a plurality of fixing columns 3. The bottom plate 1 is provided with a plurality of mounting holes 4. The ferrule fixing components 8 are provided with connecting holes 5. The fixing columns 3 are assembled in the connecting holes 5, and both ends of the fixing columns 3 are respectively installed on the inner walls of the mounting holes 4. The ferrule fixing components 8 include two side pressing blocks 6 and a plurality of middle pressing blocks 7. The two side pressing blocks 6 are respectively located on both sides of the plurality of middle pressing blocks 7. The side pressing blocks 6 are provided with side arc holes 9. Both sides of the middle pressing blocks 7 are provided with middle arc holes 10. A first jack 11 for fixing the ferrule is formed between adjacent side arc holes 9 and middle arc holes 10. A second jack 12 for fixing the ferrule is formed between adjacent middle arc holes 10.

[0033] Specifically, in this embodiment, the ferrules are fixed by splitting the first jack 11 and the second jack 12, so that the ferrules can be better clamped and locked in the first jack 11 and the second jack 12. As Figures 3 to 5 shown, the two middle arc holes 10 of the two middle pressing blocks 7 are connected to form the first jack 11. Similarly, the side arc hole 9 of the side pressing block 6 is connected to the middle arc hole 10 of the middle pressing block 7 to form the second jack 12. The diameters of the middle arc hole 10 and the side arc hole 9 are the same. The middle pressing blocks 7 and the side pressing blocks 6 are both provided with small connecting holes 5. The plurality of small connecting holes 5 are interconnected to form the connecting hole 5 for assembling the fixing columns 3. And there are two connecting holes 5. The ferrule fixing components 8 can be stably installed on the bottom plate 1 through the two fixing columns 3, as Figure 7As shown, the first locking member 2 can be optionally screwed to the bottom plate 1 and abuts against a side pressing block 6 after passing through the bottom plate 1. Therefore, the fitting tightness between the middle pressing blocks 7 and between the side pressing block 6 and the middle pressing block 7 can be controlled by adjusting the position of the first locking member 2, so as to control the clamping degree of the ferrule. Moreover, the distance between the middle pressing blocks 7 can also be adjusted to adapt to different ferrules, with higher flexibility. In actual use, first, the sizes of the first jack 11 and the second jack 12 are adjusted by the first locking member 2 so that the ferrule can be inserted into the first jack 11 and the second jack 12 and will not fall off. Then, the sizes of the first jack 11 and the second jack 12 are adjusted by the first locking member 2 to fit the ferrule, that is, the ferrule is clamped, so as to ensure that the ferrule will not fall off. Compared with the prior art in which the jacks with unadjustable sizes are set to assemble the ferrule, in this embodiment, the ferrule can be fixed by adjusting the sizes of the first jack 11 and the second jack 12, which is more flexible in application. Also, the ferrule is more difficult to fall off by the clamping method.

[0034] Furthermore, the ferrule fixing assembly 8 of this embodiment further includes a rubber pad 13. As Figure 2 shown, the bottom plate 1 includes an outer frame 20 and two partition rods 19. The two partition rods 19 are perpendicularly arranged, and both ends of the partition rods 19 are fixed to the outer frame 20. Both ends of the fixing column 3 are respectively installed on the outer frame 20 and the partition rod 19. The rubber pad 13 is installed between the side pressing block 6 and the partition rod 19. The rubber pad 13 is provided with a positioning hole 14, and the fixing column 3 passes through the positioning hole 14 and is connected to the partition rod 19.

[0035] Specifically, the rubber pad 13 is made of heat-resistant material. The first locking member 2 is arranged at one end of the ferrule fixing assembly 8, and the rubber pad 13 is arranged at the other end of the ferrule fixing assembly 8. As Figure 7 shown, when the positions of the side pressing block 6 and the middle pressing block 7 are adjusted by the first locking member 2, the rubber pad 13 can provide a certain buffering force to reduce collision and protect the side pressing block 6 and the middle pressing block 7. Moreover, it can also provide a certain elastic force to the side pressing block 6 and the middle pressing block 7, making the fit between the side pressing block 6 and the middle pressing block 7 closer, and the ferrule is less likely to fall off.

[0036] The bottom plate 1 of this embodiment is as Figure 6 shown. The bottom plate 1 includes an outer frame 20 and at least one partition rod 19. The shape of the outer frame 20 is rectangular. When the number of partition rods 19 is one, the partition rod 19 divides the outer frame 20 into two mounting holes 4. When the number of partition rods 19 is two, a "field" shape or an "eye" shape can be formed between the outer frame 20 and the partition rods 19. As Figures 7 to 9As shown, it can be set according to actual requirements. That is, the more the number of the partition rods 19, the more the outer frame 20 can be divided into installation hole positions 4. The outer frame 20 can be set to an appropriate size. The more the installation hole positions 4 are, the more the number of the ferrule fixing components 8 can be, and more ferrules can be coated simultaneously. This embodiment has no limitation.

[0037] Furthermore, a cover plate 16 is also provided in this embodiment. As Figures 10 to 12 shown, the bottom plate 1 is provided with a cover plate groove 17 for assembling the cover plate 16, and the cover plate 16 can be locked to the bottom plate 1 by common parts such as screws and bolts. The cover plate 16 is provided with a plurality of ferrule avoidance grooves 18. After the cover plate 16 is installed, the first jack 11 and the second jack 12 are exposed in the ferrule avoidance grooves 18, and both ends of the middle pressing block 7 and both ends of the side pressing block 6 are covered by the cover plate 16. Thus, while ensuring the normal installation of the ferrule, the cover plate 16 can also prevent the middle pressing block 7 and the side pressing block 6 from moving, ensuring the safe use of the first locking member 2. Moreover, the cover plate 16 can prevent the coating film layer from overflowing to the back of the product.

[0038] A second locking member 15 is also provided in this embodiment. As Figure 13 shown, the bottom plate 1 is provided with a lock hole corresponding to the fixed column 3. The lock hole is perpendicular to the fixed column 3. The second locking member 15 is locked to the lock hole, and the second locking member 15 abuts against the fixed column 3, so that the fixed column 3 is installed on the bottom plate 1. As another implementation manner, the lock hole can also be provided on the side surface of the bottom plate 1. After the second locking member 15 is locked to the lock hole, it also abuts against the fixed column 3. By adjusting the tightness of the second locking member 15, the tightness of the fixed column 3 can be adjusted, which is convenient to operate.

[0039] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention is disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments of equivalent changes, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical idea of the present invention shall fall within the scope of the technical solution of the present invention.
