Technical Field
[0001] This utility model relates to the field of optical fiber detection and positioning technology, specifically to an optical fiber detection and positioning device. Background Technology
[0002] Optical fiber, short for optical waveguide fiber, is a medium that transmits optical signals using the principle of total internal reflection. It is made of glass or plastic and has a core, cladding, and coating structure. Due to its characteristics such as resistance to electromagnetic interference and large bandwidth, it can be widely used in communication networks, medical equipment, sensing systems, and aerospace fields.
[0003] In the existing technology, general fiber optic detection and positioning devices are inconvenient to clamp fibers of different thicknesses during use, which reduces their practicality. Furthermore, during detection, the fiber cannot be rotated to detect different sides of the fiber. Utility Model Content
[0004] The purpose of this invention is to provide a positioning device for optical fiber detection, so as to solve the problem mentioned in the background art that it is inconvenient to position optical fibers of different thicknesses and cannot rotate them.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for fiber optic detection, comprising a positioning platform and a support block. The support block is located at the center of the top of the positioning platform, and both ends of the top of the positioning platform are provided with moving grooves. Support plates are provided at both ends of the top of the positioning platform corresponding to the moving grooves. Gear shafts are located at the center of both ends of the bottom of the positioning platform corresponding to the moving grooves, and gears are located at the top of each gear shaft. L-shaped toothed plates are provided inside the positioning platform on both sides of gear one. The toothed areas on the inner side of the L-shaped toothed plates mesh with gear one. A connecting rod is located at the center of the top of each L-shaped toothed plate corresponding to the support plate. The top of each connecting rod is connected to the bottom of the support plate via a moving groove. The support block has an arc-shaped groove in the middle, and an annular block is located inside the arc-shaped groove. An optical fiber is located inside the annular block. The outer middle of the annular block has evenly spaced tooth marks, and the support block corresponding to the tooth marks on the outer side of the annular block has toothed grooves. The L-shaped toothed plate moves the support plate towards the middle via the connecting rod, which in turn moves the clamping block towards the middle, thus clamping and fixing the optical fiber. This facilitates clamping optical fibers of different thicknesses. During testing, the annular block can rotate the optical fiber inside it, thereby achieving positioning and adjustment of the optical fiber and facilitating the testing of different sides of the optical fiber.
[0006] As a further technical solution of this utility model, the inner side of the annular block is uniformly provided with spring grooves, and each spring groove is provided with a spring. The other end of each spring is provided with a compression ball, and each compression ball is attached to the surface of the optical fiber. When the optical fiber is placed through the spring, the compression ball can be attached to the fiber under the action of the spring, which can initially clamp the optical fiber.
[0007] As a further technical solution of this utility model, a clamping block is provided at the middle position of the inner side of the support plate, and an arc-shaped clamping groove is provided on the inner side of the clamping block, and a clamping pad is provided in the arc-shaped clamping groove of the clamping block, so that the clamping pad on the inner side of the clamping block contacts the optical fiber, which can prevent wear.
[0008] As a further technical solution of this utility model, the bottom of the L-shaped toothed plate is provided with a slide bar, and the bottom of the positioning platform corresponding to the slide bar is provided with a slide groove. The slide groove is slidably connected to the corresponding slide bar, so that when the L-shaped toothed plate moves, it can drive the slide bar to move in the slide groove, which can make its movement more stable.
[0009] As a further technical solution of this utility model, the support blocks on both sides of the tooth groove are provided with arc-shaped limiting grooves, and the outer side of the annular block corresponding to the arc-shaped limiting groove is provided with annular limiting piece. The annular limiting piece is slidably connected to the corresponding arc-shaped limiting groove, so that when the annular block rotates, it can drive the annular limiting piece to rotate in the arc-shaped limiting groove, thereby limiting its rotation.
[0010] As a further technical solution of this utility model, a motor is provided at the bottom of the positioning platform corresponding to the gear shaft. The output end of the motor extends into the positioning platform and is connected to the gear shaft through a bearing and a coupling. The output shaft of the motor is connected to the gear shaft through the coupling, so that the motor can drive the gear shaft to rotate.
[0011] As a further technical solution of this utility model, a gear groove is provided at the middle position of the bottom of the support block, and a motor is provided at one end of the support block corresponding to the middle position of the gear groove.
[0012] As a further technical solution of this utility model, the output end of the second motor extends into the gear groove through the bearing and is provided with a second gear. The second gear meshes with the tooth marks of the annular block through the gear groove and tooth mark groove, so that the output shaft of the second motor extends into the gear groove and drives the second gear to rotate, which can drive the annular block meshing with it to rotate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The motor drives the gear on the gear shaft to rotate, which in turn causes the L-shaped toothed plates on both sides to move relative to each other. The L-shaped toothed plates then move the support plate towards the center via the connecting rod, which in turn causes the clamping block to move towards the center. This allows for the clamping and fixing of optical fibers, making it convenient for clamping optical fibers of different thicknesses.
[0015] The motor drives the gear on its shaft to rotate, which in turn drives the ring block that meshes with it to rotate. When the ring block rotates, it can drive the optical fiber inside to rotate, thereby realizing the positioning and adjustment of the optical fiber and facilitating the detection of different sides of the optical fiber.

[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] Please see Figure 1- / 5, An embodiment of this utility model provides: a positioning device for fiber optic detection, including a positioning platform 1 and a support block 2. The support block 2 is located at the center of the top of the positioning platform 1, and both ends of the top of the positioning platform 1 are provided with moving grooves 12. Support plates 5 are provided at both ends of the top of the positioning platform 1 corresponding to the moving grooves 12. Clamping blocks 3 are provided at the center of the inner side of each support plate 5, and arc-shaped clamping grooves are provided on the inner side of each clamping block 3. Clamping pads are provided within the arc-shaped clamping grooves of each clamping block 3. Clamping pads are provided at both ends of the bottom of the positioning platform 1 corresponding to the center of the moving grooves 12. There is a gear shaft 13, and the top of the gear shaft 13 is provided with a gear 7. The positioning platform 1 on both sides of the gear 7 is provided with an L-shaped toothed plate 9. The toothed marks on the inner side of the L-shaped toothed plate 9 are meshed with the gear 7. The top of the L-shaped toothed plate 9 is provided with a connecting rod 11 corresponding to the middle position of the support plate 5. The top of the connecting rod 11 is connected to the bottom of the support plate 5 through the moving groove 12. The bottom of the positioning platform 1 is provided with a motor 6 corresponding to the position of the gear shaft 13. The output end of the motor 6 extends into the positioning platform 1 and is connected to the gear shaft 13 through a bearing and a coupling.
[0024] Specifically, such as Figure 1 and Figure 2 As shown, starting motor 6 drives the gear shaft 13 connected to it to rotate, which in turn drives gear 7 to rotate. Gear 7 then drives the L-shaped toothed plates 9 meshing on both sides to move relative to each other. The L-shaped toothed plates 9 cause the connecting rod 11 to slide in the moving groove 12, which in turn causes the supporting plate 5 to move towards the center. The supporting plate 5 then causes the clamping block 3 to move towards the center, thus clamping and fixing the optical fiber. This is convenient for clamping optical fibers of different thicknesses. During clamping, the clamping pad on the inner side of the clamping block 3 increases the friction between the clamping block 3 and the optical fiber, improving the stability of the clamping block 3 in clamping the optical fiber.
[0025] The support block 2 has an arc-shaped groove in the middle, and an annular block 4 is provided in the arc-shaped groove of the support block 2. An optical fiber is provided on the inner side of the annular block 4. Tooth marks are evenly provided in the middle of the outer side of the annular block 4. Tooth mark grooves 14 are provided in the support block 2 corresponding to the tooth marks on the outer side of the annular block 4. A gear groove 17 is provided in the middle of the bottom of the support block 2. A motor 2 16 is provided at one end of the support block 2 corresponding to the middle of the gear groove 17. The output end of the motor 2 16 extends through a bearing to a gear 2 15 in the gear groove 17. The gear 2 15 meshes with the tooth marks of the annular block 4 through the gear groove 17 and the tooth mark groove 14.
[0026] Specifically, such as Figure 1 and Figure 3As shown, starting the second motor 16 can drive the second gear 15 on its shaft to rotate, which in turn drives the annular block 4 meshing with it to rotate. When the annular block 4 rotates, it can drive the optical fiber inside it to rotate, thereby realizing the positioning and adjustment of the optical fiber and facilitating the detection of different sides of the optical fiber.
[0027] Spring grooves 21 are evenly provided on the inner side of the annular block 4, and springs 18 are provided in the spring grooves 21. The other end of each spring 18 is provided with a compression ball 22, and the compression ball 22 is attached to the surface of the optical fiber.
[0028] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the optical fiber is passed through the annular block 4, and its outer side contacts the compression ball 22 first. The compression ball 22 is then squeezed against the inner wall of the annular block 4 by the elastic force of the spring 18, thereby initially clamping the optical fiber through the compression ball 22, which facilitates subsequent clamping and fixing.
[0029] The bottom of the L-shaped toothed plate 9 is provided with a slide bar 8, and the bottom of the positioning platform 1 corresponding to the slide bar 8 is provided with a groove 10, and the groove 10 is slidably connected to the corresponding slide bar 8.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, when the L-shaped toothed plate 9 moves, it can drive the slide bar 8 to move within the slide groove 10, which can make the L-shaped toothed plate 9 move more stably, thereby making the clamping effect of the support plate 5 better.
[0031] The support blocks 2 on both sides of the tooth groove 14 are provided with arc-shaped limiting grooves 19, and the outer side of the annular block 4 corresponding to the arc-shaped limiting groove 19 is provided with annular limiting pieces 20, and the annular limiting pieces 20 are slidably connected to the corresponding arc-shaped limiting groove 19.
[0032] Specifically, such as Figure 1 and Figure 4 As shown, when the annular block 4 rotates, it can drive the annular limiting piece 20 to rotate together, which can limit the rotation of the annular limiting piece 20 within the arc-shaped limiting groove 19, making the rotation of the annular block 4 more stable.
[0033] Working principle: In use, the optical fiber is passed through the annular block 4, with its outer side first contacting the compression ball 22. The compression ball 22, under the elastic force of the spring 18, compresses the inner wall of the annular block 4, thus initially clamping the optical fiber for subsequent fixation. Then, the motor 6 is started, driving the gear shaft 13 connected to it to rotate. The gear shaft 13 drives the gear 7 to rotate, causing the L-shaped toothed plates 9 on both sides to move relative to each other. The L-shaped toothed plates 9 cause the connecting rod 11 to slide within the moving groove 12, which in turn moves the support plate 5 towards the center. The support plate 5 then moves the clamping block 3 towards the center, clamping and fixing the optical fiber. This facilitates clamping optical fibers of different thicknesses. During clamping, the clamping pads on the inner side of the clamping block 3 increase... The friction between the clamping block 3 and the optical fiber improves the stability of the clamping block 3 in clamping the optical fiber. When the L-shaped toothed plate 9 moves, it can drive the slide bar 8 to move within the slide groove 10, making the movement of the L-shaped toothed plate 9 more stable, thus improving the clamping effect of the support plate 5. After clamping, the outer surface and port of the optical fiber can be inspected. After one side is inspected, the motor 16 can be started to drive the gear 15 on its shaft to rotate, which in turn drives the annular block 4 meshing with it to rotate. When the annular block 4 rotates, it can drive the optical fiber inside to rotate, thereby realizing the positioning and adjustment of the optical fiber and facilitating the inspection of different sides of the optical fiber. When the annular block 4 rotates, it can drive the annular limiting piece 20 to rotate together, which can limit the rotation of the annular limiting piece 20 within the arc-shaped limiting groove 19, making the rotation of the annular block 4 more stable.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
