Description

Technical Field

[0001] This invention relates to the field of optical cable testing technology, specifically to a multifunctional optical cable tensile testing machine. Background Technology

[0002] Optical fiber cable is a communication cable composed of optical fibers as the core transmission unit, supplemented by protective layers and reinforcing components, used for long-distance, high-capacity transmission of optical signals. Its core consists of optical fibers (made of high-purity quartz glass or plastic) that transmit light via total internal reflection, a plastic protective layer, and reinforcing components such as steel wire or aramid fiber. It features high transmission capacity, long distance, strong anti-interference, good security, and lightweight characteristics, and is widely used in communication networks, broadcasting, power, and military communications. During the production process, optical fiber cables require testing using an optical fiber tensile testing machine to assess their performance. In the prior art, patent document CN113432960B discloses a multifunctional optical cable tensile testing machine. This device includes a base with a fixed frame on its surface. A cylinder is fixed to the top inner side of the fixed frame. A first positioning structure and a second positioning structure are respectively provided on the base surface and the bottom of the cylinder. A protective cover is movably installed on the fixed frame surface. The first positioning structure includes a positioning box, inside which a first motor is fixed. The motor output shaft is connected to a connecting block. It initially clamps one end of the optical cable through the relative movement of two fixed plates, and then the connecting block drives a rotating cylinder to rotate, winding around the end of the optical cable to complete the fixation, reducing manual operation. However, this device still has shortcomings: when clamping and fixing the optical cable, clamping force is applied only from both sides. This single-point force distribution leads to uneven clamping force distribution, which not only easily causes the optical cable to slip during the tensile test, affecting the stability and accuracy of the test data; more importantly, increasing the clamping force to prevent slippage can cause local pressure concentration, resulting in an imbalance of force across the optical cable cross-section, potentially causing the outer protective layer to crack or even damaging the internal optical fiber structure. This will not only directly damage the optical cable sample, but may also cause the optical cable to break at an unexpected location, resulting in the test results failing to accurately reflect its actual tensile performance and seriously affecting the scientific validity and reliability of the test.

[0003] The multi-functional optical cable tensile testing machine in the aforementioned patent document has the problem of poor clamping effect. Therefore, a multi-functional optical cable tensile testing machine is proposed. Summary of the Invention

[0004] To address the aforementioned issues, a multifunctional optical cable tensile testing machine is provided, which solves the problem of poor clamping effect in existing devices.

[0005] To address the problems of existing technologies, the present invention provides a multifunctional optical cable tensile testing machine, comprising: a mounting plate, a driving device, and two clamping devices, wherein one side of the mounting plate is fixedly connected to one side of the driving device, and both clamping devices are threadedly connected to the inside of the driving device; The clamping device includes a drive rod, a rotating rod, and a threaded cylinder. The drive rod is threadedly connected to the inside of the drive device. A rotating groove is formed inside the drive rod. The rotating rod is rotatably connected to the rotating groove. One side of the rotating rod is fixedly connected to one side of the threaded cylinder. A spur gear is fixedly connected between the rotating rod and the threaded cylinder. The spur gear meshes with the side of the mounting plate closest to the drive device. An installation groove is formed inside the threaded cylinder. A fixing plate is fixedly connected to one side of the bottom of the installation groove. The clamping assembly is slidably connected to the side of the fixing plate away from the installation groove.

[0006] As a technical solution of the present invention, the clamping assembly includes: a driven gear, a driving gear, multiple guide rods, multiple clamping rods, and multiple clamping plates. One side of the driven gear and the driving gear are rotatably connected to one side of the fixed plate, and the driven gear meshes with the driving gear. The driven gear is provided with multiple curved grooves. Multiple sliding grooves are opened inside the fixed plate. Sliding rods are slidably connected in each of the multiple sliding grooves. One side of each of the multiple sliding rods is fixedly connected to one side of each of the multiple guide rods and the multiple clamping rods. The multiple guide rods are slidably connected to the multiple curved grooves respectively. The side of each of the multiple clamping rods away from the multiple sliding rods is fixedly connected to one side of each of the multiple clamping plates respectively.

[0007] As a technical solution of the present invention, the plurality of clamping plates are all arc-shaped, and the plurality of clamping plates surround to form a cylindrical clamping cavity.

[0008] As one technical solution of the present invention, a first drive motor is fixedly connected to the side of the drive gear near the fixed plate, and the side of the first drive motor near the drive gear is fixedly connected to the outer wall of the threaded cylinder.

[0009] As one technical solution of the present invention, the plurality of sliding rods are all symmetrically cross-shaped, and the outer sidewalls of the plurality of sliding rods are respectively attached to the inner sidewalls of the plurality of sliding grooves.

[0010] As one technical solution of the present invention, a guide rail is fixedly connected to the side of the mounting plate near the driving device, a rack is fixedly connected inside the guide rail, the spur gear extends into the inside of the guide rail, and the spur gear meshes with the rack.

[0011] As one technical solution of the present invention, the driving device includes: a mounting frame, a second driving motor, and a double-ended threaded rod. One side of the second driving motor is fixedly connected to one side of the mounting plate, the output end of the second driving motor is fixedly connected to one side of the double-ended threaded rod, the side of the double-ended threaded rod away from the second driving motor is rotatably connected to the mounting frame, one side of the mounting frame is fixedly connected to the side of the mounting plate near the second driving motor, the driving rod is threadedly connected to the double-ended threaded rod, and the two sides of the driving rod away from the double-ended threaded rod are in contact with the mounting frame.

[0012] As one technical solution of the present invention, the mounting plate is fixedly connected to both ends of the side near the mounting frame, and a transparent cover is snapped onto the support plate. The mounting frame is fixedly connected to the side away from the mounting plate, and a guide plate is fixedly connected to the guide plate. Multiple guide rods are fixedly connected to the guide plate.

[0013] The advantages of this invention compared to the prior art are: 1. This application uses a first drive motor to drive a drive gear and a driven gear to rotate. During the rotation of the driven gear, the curved groove on the driven gear will squeeze and drive multiple guide rods to move closer to each other. The multiple guide rods drive multiple sliding rods and multiple clamping rods to move synchronously. At this time, the multiple clamping rods drive multiple clamping plates to clamp and fix one end of the optical cable on the outside. When this device is used, the clamping surface is wider than that of traditional devices, and the optical cable can be clamped at multiple points. The clamping is more stable and can protect the optical cable to avoid damage.

[0014] 2. This application uses a drive device to drive two clamping devices to move relatively far apart. After the clamping group clamps and fixes both ends of the optical cable, the drive device drives the two clamping devices to move relatively far apart in a straight line. At this time, through the spur gear and rack, the two clamping devices will also rotate synchronously in opposite directions. This allows the optical cable to be wound around the outside of the threaded cylinder, further improving the fixing effect of the device. The opposite straight line movement of the two clamping devices can be used to perform a tensile test on the optical cable.

[0015] 3. With the support plate and transparent cover set in this application, during the tensile test of the optical cable, the staff can clearly observe the test results of the optical cable through the transparent cover. The transparent cover can also block the optical cable to prevent the optical cable from breaking and injuring the staff, making the device safer to use. Attached Figure Description

[0025] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0026] See Figures 1-8 As shown, a multifunctional optical cable tensile testing machine includes: a mounting plate 1, a driving device, and two clamping devices. One side of the mounting plate 1 is fixedly connected to one side of the driving device, and both clamping devices are threadedly connected to the inside of the driving device. The clamping device includes a drive rod 2, a rotating rod 3, and a threaded cylinder 4. The drive rod 2 is threadedly connected to the inside of the drive device. A rotating groove 5 is provided inside the drive rod 2. The rotating rod 3 is rotatably connected to the rotating groove 5. One side of the rotating rod 3 is fixedly connected to one side of the threaded cylinder 4. A spur gear 6 is fixedly connected between the rotating rod 3 and the threaded cylinder 4. The spur gear 6 meshes with the side of the mounting plate 1 closest to the drive device. An mounting groove 7 is provided inside the threaded cylinder 4. A fixing plate 8 is fixedly connected to one side of the bottom of the mounting groove 7. The clamping assembly is slidably connected to the side of the fixing plate 8 away from the mounting groove 7.

[0027] It should be noted that in the above device, both ends of the optical cable are inserted into the threaded cylinder 4. At this time, the first drive motor 17 is activated, which drives multiple clamping plates 13 to clamp and fix the optical cable on multiple sides. After one side of the optical cable is clamped and fixed, the other side of the optical cable is placed along the guide rod 26 and clamped and fixed by the other device. At this time, the second drive motor 21 is activated, which drives two drive rods 2 to move synchronously and relatively away from each other. Through the set rotating rod 3 and spur gear 6, the spur gear 6 is driven by the driven rod 2 During the linear motion, the spur gear 6 rubs against the rack 19, causing the spur gear 6 to rotate. When the spur gear 6 rotates, it drives the rotating rod 3 and the threaded cylinder 4 to rotate synchronously. At this time, the optical cable can be wound around the outside of the threaded cylinder 4. The outside of the threaded cylinder 4 is provided with a threaded groove. The optical cable is wound along the threaded groove, making the optical cable wound more secure. This prevents the wound parts of the optical cable from being squeezed and damaged when stretched. When the device is in use, the two drive rods 2 can be used to move the two ends of the optical cable away from each other. At this time, a tensile test can be performed on the optical cable, making the device more stable in use.

[0028] The clamping assembly includes: a driven gear 9, a driving gear 10, multiple guide rods 11, multiple clamping rods 12, and multiple clamping plates 13. One side of the driven gear 9 and the driving gear 10 are rotatably connected to one side of the fixed plate 8, and the driven gear 9 meshes with the driving gear 10. The driven gear 9 is provided with multiple curved grooves 14. The fixed plate 8 has multiple sliding grooves 15 inside, and sliding rods 16 are slidably connected within each sliding groove 15. One side of each sliding rod 16 is fixedly connected to one side of each guide rod 11 and each clamping rod 12. The guide rods 11 are slidably connected to the multiple curved grooves 14 respectively. The clamping rods 12 are located away from the sliding rods 16. The drive gear 10 is fixedly connected to one side of the multiple clamping plates 13. The multiple clamping plates 13 are all arc-shaped and form a cylinder. The drive gear 10 is fixedly connected to the first drive motor 17 on the side near the fixed plate 8. The first drive motor 17 is fixedly connected to the outer wall of the threaded cylinder 4 on the side near the drive gear 10. The multiple sliding rods 16 are all symmetrically arranged in a cross shape. The outer walls of the multiple sliding rods 16 are respectively attached to the inner walls of the multiple sliding grooves 15. The mounting plate 1 is fixedly connected to the guide rail 18 on the side near the drive device. The rack 19 is fixedly connected inside the guide rail 18. The spur gear 6 extends into the guide rail 18 and meshes with the rack 19.

[0029] It should be noted that when the above device is in use, when one end of the optical cable is inserted between the multiple clamping plates 13, the first drive motor 17 is activated. The first drive motor 17 drives the drive gear 10 to rotate. When the drive gear 10 rotates, it drives the passive gear 9 to rotate synchronously. When the passive gear 9 rotates, the multiple curved grooves 14 on the passive gear 9 will squeeze the multiple guide rods 11. The multiple guide rods 11 are restricted by the multiple sliding rods 16 and the multiple sliding grooves 15. At this time, the multiple guide rods 11 will drive the multiple sliding rods 16 to slide within the multiple sliding grooves 15. At this time, the multiple sliding rods 16 will move closer to each other simultaneously. Multiple sliding rods 16 simultaneously drive multiple clamping rods 12 and multiple clamping plates 13 to move closer to each other in a synchronous manner, so that the multiple clamping plates 13 can clamp and fix the optical cable on multiple sides. The multiple clamping plates 13 are arc-shaped and can form a cylinder, so that the multiple clamping plates 13 can clamp and fix the optical cable more stably. The multiple arc-shaped clamping plates 13 can clamp the outer side of the optical cable at multiple points, so that the force on the outer side of the optical cable is more uniform when clamping the optical cable. This makes the clamping more stable and protects the optical cable during tensile testing, avoiding damage to the optical cable and reducing the loss of the optical cable.

[0030] The driving device includes: a mounting frame 20, a second drive motor 21, and a double-ended threaded rod 22. One side of the second drive motor 21 is fixedly connected to one side of the mounting plate 1. The output end of the second drive motor 21 is fixedly connected to one side of the double-ended threaded rod 22. The side of the double-ended threaded rod 22 away from the second drive motor 21 is rotatably connected to the mounting frame 20. One side of the mounting frame 20 is fixedly connected to the side of the mounting plate 1 near the second drive motor 21. The drive rod 2 is threadedly connected to the double-ended threaded rod 22, and the two sides of the drive rod 2 away from the double-ended threaded rod 22 are in contact with the mounting frame 20. Support plates 23 are fixedly connected to both ends of the side of the mounting plate 1 near the mounting frame 20. A transparent cover 24 is snapped onto the support plate 23. A guide plate 25 is fixedly connected to the side of the mounting frame 20 away from the mounting plate 1. Multiple guide rods 26 are fixedly connected to the guide plate 25.

[0031] It should be noted that in the above device, after the two ends of the optical cable are clamped and fixed by multiple clamping plates 13 and the optical cable is placed on the two guide rods 26, the second drive motor 21 is started. The second drive motor 21 drives the double-headed threaded rod 22 to rotate. When the double-headed threaded rod 22 rotates, since the two drive rods 2 are in contact with the mounting frame 20 on both sides away from the double-headed threaded rod 22, the two drive rods 2 are restricted by the mounting frame 20. The two drive rods 2 will move in a relatively far straight line along the double-headed threaded rod 22. At this time, the device can perform a tensile test on the optical cable. When the device is in use, the guide plate 25 and the guide rod 26 make the optical cable more stable during movement, making the device more effective. The transparent cover 24 does not affect the staff's observation of the optical cable tensile results and can protect the staff, making the device safer to use.

[0032] The working principle of this device is as follows: In use, both ends of the optical cable are inserted into the threaded cylinder 4. When one end of the optical cable is inserted between the multiple clamping plates 13, the first drive motor 17 is activated. The first drive motor 17 drives the drive gear 10 to rotate. When the drive gear 10 rotates, it drives the driven gear 9 to rotate synchronously. When the driven gear 9 rotates, the multiple curved grooves 14 on the driven gear 9 will squeeze the multiple guide rods 11. The multiple guide rods 11 are restricted by the multiple sliding rods 16 and the multiple sliding grooves 15. At this time, the multiple guide rods 11 will drive the multiple sliding rods 16 to move in the multiple sliding grooves. Within 15, the sliding rods 16 move closer to each other simultaneously. These sliding rods 16 simultaneously drive the clamping rods 12 and clamping plates 13 to move closer to each other in a synchronized manner. This allows the clamping plates 13 to clamp and fix the optical cable from multiple sides. The clamping plates 13 are arc-shaped and can form a cylindrical shape, enabling more stable clamping and fixing of the optical cable. Furthermore, the multiple arc-shaped clamping plates 13 can clamp the outer side of the optical cable at multiple points, resulting in greater force on the outer side of the optical cable during clamping. The uniform clamping ensures more stable clamping and protection of the optical cable during tensile testing, preventing clamping damage and reducing cable loss. After one side of the optical cable is clamped and fixed, the other side is placed along the guide rod 26 and clamped and fixed by the other device. At this time, the second drive motor 21 is activated, driving the two drive rods 2 to move synchronously and relatively away. Through the rotating rod 3 and the spur gear 6, the spur gear 6 moves linearly driven by the drive rods 2, and the spur gear 6 rotates... Gear 6 rubs against rack 19, causing spur gear 6 to rotate. When spur gear 6 rotates, it drives rotating rod 3 and threaded cylinder 4 to rotate synchronously. At this time, the optical cable can be wound around the outside of threaded cylinder 4. Threaded grooves are provided on the outside of threaded cylinder 4. The optical cable is wound along the threaded grooves, making the optical cable wound more secure. This prevents the wound part of the optical cable from squeezing and damaging each other when the optical cable is stretched. When the device is in use, the two drive rods 2 can drive the two ends of the optical cable to move away from each other. At this time, the optical cable can be subjected to a tensile test, making the device more stable in use.

[0033] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
