Description

Technical Field

[0001] This utility model relates to the field of optical cable testing technology, specifically to an optical cable morphology tensile processing testing device. Background Technology

[0002] Optical cables are widely used in communications, power, broadcasting, and other fields. In these applications, optical cables may be subjected to various external forces, causing morphological stretching. Therefore, morphological stretching testing of optical cables is essential during the manufacturing process. This testing can promptly detect potential damage caused by stretching, such as fiber breakage or sheath damage, preventing communication interruptions and degraded signal transmission quality due to performance degradation, and ensuring the stable and reliable operation of various systems.

[0003] As disclosed in the patent announcement CN219104551U, a device for testing the tensile strength of optical cables relates to the field of optical cable testing technology. It includes a base plate, with a base and a fixed seat fixedly connected to the top of the base plate. A traction and tensioning mechanism is provided on the base. The traction and tensioning mechanism includes linear guide grooves at both ends of the top of the base, with guide seats slidably connected within each of the two linear guide grooves. An optical cable connecting assembly is fixedly connected between the two guide seats, and the fixed seat also has an optical cable connecting assembly fixedly provided. The optical cable connecting assembly includes an installation roller with a winding groove on its outer surface. This invention, by setting two optical cable connecting assemblies, enables the winding and installation of both ends of the optical cable, and allows for fixing one end of the optical cable while conducting tensile testing on the other end. The traction and tensioning mechanism enables the stretching of the optical cable and the detection of the stretching distance and tensile force. This device has a simple structure, is easy to operate, has good tensile strength testing effect on optical cables, and is highly practical.

[0004] While the aforementioned solution can achieve the stretching of optical cables and the detection of stretching distance and tensile force by setting up a traction stretching mechanism, this utility model occupies a large area. Furthermore, during the testing process, it uses installation rollers to wind and fix the optical cable, which makes it difficult to ensure the axial perpendicularity of the optical cable during stretching, resulting in uneven distribution of tensile force across the cable and inaccurate test results. Therefore, we propose an optical cable morphology stretching processing and testing device that solves the problems of difficulty in ensuring the perpendicularity of the stretched optical cable and the large footprint of the existing utility model, improving the testing accuracy and saving space. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the tensile processing of optical cables to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fiber optic cable morphology stretching and testing device includes a base, and a first clamping mechanism and a stretching mechanism are provided on the top surface of the base.

[0008] As a further embodiment of this utility model: the stretching mechanism includes a limiting post, a top support plate is fixedly provided at the top of the limiting post, a lifting screw is threadedly connected to the top support plate, a limiting plate is slidably connected to the outside of the limiting post, the bottom end of the lifting screw is rotatably connected to the limiting plate, and a second clamping mechanism is fixedly installed on the bottom surface of the limiting plate.

[0009] As a further embodiment of this utility model: the second clamping mechanism is located directly above the first clamping mechanism, and the second clamping mechanism has the same structure as the first clamping mechanism.

[0010] As a further embodiment of this utility model: the first clamping mechanism includes a base plate, which is fixedly installed on the top surface of the base by screws. A first fixing block and a second fixing block are fixedly provided on the top surface of the base plate. An arc-shaped groove is provided on the side of the first fixing block near the second fixing block. A threaded rod is threadedly connected to the center of the second fixing block. A pressing head is rotatably connected to one end of the threaded rod near the first fixing block, and a rotating handle is fixedly provided at the other end. A keyway is provided inside the rotating handle.

[0011] As a further embodiment of this utility model: a rangefinder is fixedly installed on the bottom surface of the top support plate, a Z-shaped frame is fixedly installed on the top surface of the top support plate, a servo motor is fixedly installed on the top of the Z-shaped frame, and an active gear is fixedly connected to the output end of the servo motor.

[0012] As a further embodiment of this utility model: the outer side of the lifting screw is threaded with a driven tooth, the bottom end of the driven tooth is rotatably connected to the top support plate, and the driven tooth and the driving tooth are meshed with each other.

[0013] Compared with the prior art, this utility model provides a device for testing the tensile processing of optical cables, which has the following advantages:

[0014] 1. This optical cable morphology stretching and testing equipment, through a first clamping mechanism set on the top surface of the base and a second clamping mechanism set directly above the first clamping mechanism, allows the two ends of the optical cable to be tested to be inserted into the arc-shaped grooves of the first and second clamping mechanisms respectively. By rotating the threaded rod clockwise, the extrusion head moves towards the arc-shaped groove until the extrusion head tightly clamps the optical cable in the arc-shaped groove. This clamping method provides a reference point for fixing the two ends of the optical cable through the arc-shaped groove, thereby ensuring the perpendicularity of the optical cable during the stretching process. This allows the tensile force to be evenly distributed in all parts of the optical cable when subjected to tensile stress, improving the accuracy of the test results.

[0015] 2. This optical cable morphology stretching and testing equipment, through the longitudinal limiting column, lifting screw and limiting plate set in the stretching mechanism, enables the equipment to achieve the testing effect by lifting the second clamping mechanism through the lifting of the limiting plate when performing stretching testing on the optical cable. Its structure is compact and occupies a small area, which not only facilitates transportation, but also improves the space utilization of the workplace.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A device for testing the shape and tensile processing of optical cables, such as... Figures 1-4 As shown, the device includes a base 1. The top surface of the base 1 is provided with a first clamping mechanism 2 and a tensioning mechanism 3. The tensioning mechanism 3 includes a limiting post 31. A top support plate 32 is fixedly installed at the top of the limiting post 31. A lifting screw 33 is threadedly connected to the top support plate 32. A limiting plate 34 is slidably connected to the outside of the limiting post 31. The bottom end of the lifting screw 33 is rotatably connected to the limiting plate 34. A second clamping mechanism 4 is fixedly installed on the bottom surface of the limiting plate 34. A rangefinder 5 is fixedly installed on the bottom surface of the top support plate 32. A Z-shaped frame 35 is fixedly installed on the top surface of the top support plate 32. A servo motor 36 is fixedly installed at the top of the Z-shaped frame 35. An active gear 37 is fixedly connected to the output end of the servo motor 36. A driven gear 38 is threadedly connected to the outside of the lifting screw 33. The bottom end of the driven gear 38 is rotatably connected to the top support plate 32. The driven gear 38 and the active gear 37 are meshed with each other.

[0025] In this embodiment, the servo motor 36 drives the active gear 37 to rotate. The servo motor 36 is a forward and reverse motor, which drives the driven gear 38 to rotate synchronously. This further causes the lifting screw 33 to move the limiting plate 34 up and down until the optical cable is straightened. The servo motor 36 is then turned off. At this time, the rangefinder 5 installed on the bottom surface of the top support plate 32 is started to take an initial measurement reading of the distance between the bottom surface of the top support plate 32 and the top surface of the limiting plate 34. Then, the servo motor 36 is started again, causing the lifting screw 33 to drive the limiting plate 34 to rise vertically. The changes in the data of the rangefinder 5 and the state of the optical cable are observed to achieve the effect of optical cable morphology stretch detection.

[0026] like Figures 1-4 As shown, the second clamping mechanism 4 is located directly above the first clamping mechanism 2. The second clamping mechanism 4 has the same structure as the first clamping mechanism 2. The first clamping mechanism 2 includes a base plate 21, which is fixedly installed on the top surface of the base 1 by screws. A first fixing block 22 and a second fixing block 23 are fixedly provided on the top surface of the base plate 21. An arc-shaped groove 24 is provided on the side of the first fixing block 22 near the second fixing block 23. A threaded rod 25 is threadedly connected to the center of the second fixing block 23. A pressing head 26 is rotatably connected to one end of the threaded rod 25 near the first fixing block 22, and a rotating handle 27 is fixedly provided on the other end. A keyway 271 is provided inside the rotating handle 27.

[0027] In this embodiment, by inserting both ends of the optical cable to be tested into the arc-shaped grooves 24 of the first clamping mechanism 2 and the second clamping mechanism 4 respectively, and by rotating the threaded rod 25 clockwise, the pressing head 26 moves towards the arc-shaped groove 24 until the pressing head 26 clamps the optical cable in the arc-shaped groove 24. During the clamping process, by using the keyway 271 opened inside the rotating handle 27, the operator can use a tool that matches the keyway 271 to further rotate the threaded rod 25 to ensure the clamping tightness of the optical cable.

[0028] In this embodiment, the optical cable morphology stretching and testing equipment is used by first inserting both ends of the optical cable to be tested into the arc-shaped grooves 24 of the first clamping mechanism 2 and the second clamping mechanism 4, respectively. By rotating the threaded rod 25 clockwise, the extrusion head 26 moves towards the arc-shaped groove 24 until the extrusion head 26 clamps the optical cable in the arc-shaped groove 24. During the clamping process, by using the keyway 271 opened inside the rotating handle 27, the operator can use a tool that matches the keyway 271 to further rotate the threaded rod 25 to ensure the clamping tightness of the optical cable. Then, the servo motor 36 drives the active gear 37 to rotate. The servo motor 36 is a forward and reverse motor, which drives the driven gear 38 to rotate synchronously. This further causes the lifting screw 33 to move the limiting plate 34 up and down until the optical cable is straightened. The servo motor 36 is then turned off. At this time, the rangefinder 5 installed on the bottom surface of the top support plate 32 is started to take an initial measurement reading of the distance between the bottom surface of the top support plate 32 and the top surface of the limiting plate 34. Then, the servo motor 36 is started again, causing the lifting screw 33 to drive the limiting plate 34 to rise vertically. The changes in the data of the rangefinder 5 and the state of the optical cable are observed to achieve the effect of optical cable morphology stretching detection. The model of the rangefinder 5 is LZ-KELR-TE20. This detection equipment has a simple structure, occupies a small area, is easy to transport, and can ensure the axial perpendicularity of the optical cable during the detection process, thereby improving the accuracy of the optical cable detection data.
