Description

Technical Field

[0001] This utility model relates to the technical field of grinding positioning devices, and more specifically, to an angle positioning device for grinding FA fiber arrays. Background Technology

[0002] FA fiber array polishing is a key step in manufacturing high-quality fiber arrays. An angle positioning device can ensure that the fiber array maintains a precise angle and position during the polishing process, which is crucial for ensuring the transmission performance and stability of the fiber array.

[0003] Existing polishing devices require precise angle positioning when polishing the ends of FA fiber arrays. For typical fiber coupling applications, the polishing angle for the fiber end face is typically around 8°. This angle helps reduce Fresnel reflections, optimizes the transmission efficiency of optical signals at the fiber interface, reduces return loss, and ensures the stability and quality of optical signal transmission. FA fiber arrays consist of multiple fibers, and polishing and fixing require individual fixing of each fiber. Existing devices can only operate on a one-by-one basis, which is extremely inconvenient. Therefore, we propose an angle positioning device for polishing FA fiber arrays. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an angle positioning device for FA fiber array polishing, so as to solve the technical problem that the current fiber polishing angle fixing device adopts a single fixed structure and is cumbersome to operate.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an angle positioning device for FA fiber array polishing, comprising an outer ring, an inner disk, a plug-in mechanism, a locking mechanism, and an adjusting plate. A hoisting rod is fixed at the middle of the upper end face of the inner disk. A side interface is opened in the outer annular array of the inner disk. A wiring groove is opened at equal intervals in the side interface, and a docking piece is fixed inside the wiring groove. An adjusting port is opened at both ends of the side interface. The outer ring is fixed to the outside of the inner disk by connecting screws after being sleeved. An insertion port is opened in the outer annular array of the outer ring. The plug-in mechanism is slidably inserted into the insertion port. The plug-in mechanism is composed of a plug-in box. Side blocks are fixed at both ends of the plug-in box, and a locking port is opened at the outer end of the side blocks.

[0006] During installation, the optical fiber is passed through the cable tray and guided by the inclined surface of the connector, allowing the polished end of the fiber to pass through the port. After all the optical fibers in one side interface are installed, the connector box is pressed and pushed, causing it to move into the side interface. During this movement, the side block moves, pressing down the pull rod through the inclined opening of the locking port. When the pull rod reaches its lowest position, the spring returns, causing the L-shaped pull rod to move to the top of the longitudinal opening of the locking port, thus locking the connector box. To separate the connector box, manually press the top of the pull rod and pull it back. Through the above structural design, this device uses sliding insertion to fix the fiber heads of the entire optical fiber array. To reduce the difficulty of operation, when the plug-in box drives the locking mechanism to move, the fixing plate pushes the adjusting plate. When the inclined block of the adjusting plate contacts the bottom opening of the docking part and is limited, it continues to push to unfold the connected rubber sleeve. At this time, the rear end of the adjusting plate retracts into the storage groove. When the inclined pressure surface clamps and fixes the optical fiber head with the inner side of the inclined block, it stops. At this time, the optical fiber head is affected by the tilt angle and completes the fixing of the corresponding angle. Through the above structural design, this device clamps by two-stage displacement. The first stage displacement positions the inclined block, and the second stage displacement allows the inclined block to cooperate with the inclined pressure surface to complete the clamping and positioning of the fixed angle, ensuring clamping stability while preventing clamping damage caused by excessive force on the squeezing surface.

[0007] Preferably, spring-loaded components are provided on both sides of the insertion port. The spring-loaded components consist of a spring and a pull rod. The lower end of the pull rod is slidably inserted into the adjustment port, and the spring connects the top of the pull rod and the outer ring.

[0008] Preferably, the pull rod is L-shaped, and the lower end of the pull rod passes through the side opening of the adjustment port and slides into the locking port of the side block, wherein the locking port is T-shaped.

[0009] Preferably, the insertion port corresponds to the side interface, and pressure blocks are evenly distributed on the inner side of the plug box, with the locking mechanism embedded in the lower side of the pressure blocks.

[0010] Preferably, the locking mechanism is composed of a fixing plate, the upper front side of the fixing plate is provided with an inclined pressing surface, the lower front side of the fixing plate is provided with a storage groove, and the two ends of the storage groove are fixedly installed with fixing sleeves.

[0011] Preferably, the adjusting plate is slidably inserted into the storage groove, and both ends of the adjusting plate are provided with ports, with a crossbar fixed inside one end of the port. The fixing sleeve is located inside the port, and a rubber sleeve is fitted between the fixing sleeve and the crossbar.

[0012] Preferably, the front end of the adjusting plate is fixed with an inclined block, and the bottom inner side of the inclined block is provided with a through hole, and the inclined block is adapted to the inclined pressing surface and the docking part.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs a plug-in mechanism that allows optical fibers to pass through the wiring groove and be guided by the inclined surface on the connector to allow the polished end of the optical fiber to pass through the port. After all the optical fibers in one side interface are installed, pressing and pushing the plug-in box moves the plug-in box into the side interface. During the movement, the side block moves and the pull rod is pressed down through the inclined opening of the locking port. When the pull rod moves to the bottom, the spring rebound causes the L-shaped pull rod to move to the top of the longitudinal opening of the locking port, thus locking the plug-in box. When separation is required, manually pressing the top of the pull rod and pulling it backward will complete the separation of the plug-in box. Through the above structural design, this device can fix the optical fiber head of the entire optical fiber array through sliding plug-in, reducing the difficulty of operation.

[0015] 2. This utility model also incorporates an adjustable plate design. When the plug-in box moves the locking mechanism, the fixing plate pushes the adjustable plate. When the inclined block of the adjustable plate contacts the bottom opening of the connector, it is limited and continuously pushed to unfold the connected rubber sleeve. At this time, the rear end of the adjustable plate retracts into the receiving groove. When the inclined pressure surface clamps and fixes the fiber optic head with the inner side of the inclined block, it stops. At this time, the fiber optic head is affected by the tilt angle and completes the fixing of the corresponding angle. Through the above structural design, this device clamps the fiber optic head through a two-stage displacement. The first stage displacement positions the inclined block, and the second stage displacement allows the inclined block to cooperate with the inclined pressure surface to complete the clamping and positioning at a fixed angle, ensuring clamping stability while preventing clamping damage caused by excessive force on the squeezing surface.

[0026] like Figures 1 to 4 As shown, this utility model relates to an angle positioning device for FA fiber array polishing, comprising an outer ring 2, an inner disk 3, a plugging mechanism 4, a locking mechanism 6, and an adjusting plate 7. A lifting rod 1 is fixed at the middle of the upper end face of the inner disk 3. A side interface 302 is provided on the outer ring array of the inner disk 3. Cable trays 303 are provided at equal intervals in the side interface 302, and a connecting piece 304 is fixed inside the cable tray 303. Adjustment ports 301 are provided at both ends inside the side interface 302. Both sides of the insertion port 202 are provided with spring-loaded components 5, which consist of a spring 501 and a pull rod 502. The lower end of the pull rod 502 is slidably inserted into the adjustment port 301. The spring 501 connects the top of the pull rod 502 and the outer ring 2. The pull rod 502 has an L-shaped design, and the lower end of the pull rod 502 passes through the side opening of the adjustment port 301 and is slidably inserted into the locking port 404 of the side block 403. The locking port 404 has a 7-shaped design. The insertion port 202 and the side interface 302 are connected. Correspondingly, pressure blocks 402 are evenly distributed on the inner side of the plug box 401. The locking mechanism 6 is embedded in the lower side of the pressure block 402. The optical fiber is passed through the cable tray 303 and guided by the inclined surface on the connector 304 so that the polished end of the optical fiber passes through the through port 705. After all the optical fibers in the side interface 302 are installed, the plug box 401 is pressed and pushed, and the plug box 401 is moved into the side interface 302. During the movement, the side block 403 is moved and the pull rod 502 is pressed down through the inclined opening of the locking port 404. When the pull rod 502 is moved to the bottom, the spring 501 returns and moves the L-shaped pull rod 502 to the top of the longitudinal opening of the locking port 404. At this time, the plug box 401 is locked. When it is necessary to separate, the plug box 401 can be separated by manually pressing the top of the pull rod 502 and pulling it backward. Through the above structural design, the device can fix the optical fiber head of the entire optical fiber array through sliding plugging, reducing the difficulty of operation.

[0027] like Figures 1 to 4As shown, this utility model relates to an angle positioning device for FA fiber array polishing, including an outer ring 2, an inner disk 3, a plugging mechanism 4, a locking mechanism 6, and an adjusting plate 7. The outer ring 2 is sleeved and fixed to the outside of the inner disk 3 by a connecting screw 201. The outer ring 2 has an insertion port 202 on its outer ring array. The plugging mechanism 4 is slidably plugged into the insertion port 202. The plugging mechanism 4 is composed of a plug box 401. Both ends of the plug box 401 are fixed with side blocks 403, and the side blocks 403 are... The locking mechanism 6 is composed of a fixed plate 601, with a locking port 404 at one end. The upper front side of the fixed plate 601 has a beveled pressure surface 603, and the lower front side of the fixed plate 601 has a storage groove 602. Fixed sleeves 604 are fixedly installed at both ends of the storage groove 602. An adjusting piece 7 is slidably inserted into the storage groove 602. Both ends of the adjusting piece 7 have ports 701, and a crossbar 703 is fixed to one end of each port 701. The fixed sleeve 604 is located inside the port 701 and is fixed... A rubber sleeve 702 is fitted between the fixed sleeve 604 and the crossbar 703. An inclined block 704 is fixed to the front end of the adjusting plate 7, and the bottom inner side of the inclined block 704 has a through-hole 705. The inclined block 704 is adapted to the inclined pressing surface 603 and the mating part 304. When the insertion box 401 drives the locking mechanism 6 to move, the fixed plate 601 pushes the adjusting plate 7. When the inclined block 704 of the adjusting plate 7 contacts the bottom opening of the mating part 304 and is limited, continuous pushing causes the connected rubber sleeve 702 to unfold. At this time, the adjusting plate 7... The rear end retracts into the receiving groove 602. It stops when the inclined pressure surface 603 clamps and fixes the fiber head with the inner side of the inclined block 704. At this time, the fiber head is affected by the tilt angle and completes the fixation of the corresponding angle. Through the above structural design, the device clamps the fiber head by two-stage displacement. The first stage displacement positions the inclined block 704, and the second stage displacement allows the inclined block 704 to cooperate with the inclined pressure surface 603 to complete the clamping and positioning at a fixed angle. This ensures clamping stability and prevents clamping damage caused by excessive force on the squeezing surface.

[0028] Working Principle: This embodiment provides an angle positioning device for FA fiber array polishing. During use and installation, the fiber is passed through the cable tray 303 and guided by the inclined surface on the connector 304, so that the polishing end of the fiber passes through the through-hole 705. After all the fibers in one side interface 302 are installed, the plug box 401 is pressed and pushed, and the plug box 401 moves into the side interface 302. During the movement, the side block 403 moves, and the pull rod 502 is pressed down through the inclined opening of the locking port 404. When the pull rod 502 moves to the bottom, the spring 501 returns the L-shaped pull rod 502 to the locking port 404. At the top of the longitudinal opening 04, the plug box 401 is locked. When separation is required, manually press the top of the pull rod 502 and pull it back to complete the separation of the plug box 401. When the plug box 401 drives the locking mechanism 6 to move, the fixing plate 601 pushes the adjusting plate 7. When the inclined block 704 of the adjusting plate 7 contacts the bottom opening of the docking part 304 and is limited, it continues to push to unfold the connected rubber sleeve 702. At this time, the rear end of the adjusting plate 7 retracts into the storage groove 602. When the inclined pressure surface 603 and the inner side of the inclined block 704 clamp and fix the optical fiber head, it stops. At this time, the optical fiber head is affected by the tilt angle and completes the fixation of the corresponding angle.
