Description

Technical Field

[0001] This utility model relates to the field of optical cable testing technology, and in particular to an optical cable tensile testing device. Background Technology

[0002] With the rapid development of the communications industry, optical cables, as a crucial carrier of information transmission, directly impact communication quality and stability through their physical properties. Tensile performance is a key indicator of mechanical strength in the manufacturing and quality inspection of optical cables. Traditional methods for testing optical cable tensile strength often rely on manual operation or simple clamping devices for fixing and applying force. These methods suffer from problems such as insecure clamping, uneven force distribution, and low testing accuracy, easily leading to significant deviations in test data and even causing damage or breakage of the optical cable, thus affecting the accuracy and repeatability of the test results. Therefore, we propose an optical cable tensile testing device. Utility Model Content

[0003] The main purpose of this invention is to provide an optical cable tension testing device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fiber optic cable tensile testing device includes a base plate, a U-shaped testing frame fixedly installed on the upper end of the base plate, a controller fixedly installed on the U-shaped testing frame, and sliding grooves on both the left and right sides of the inner surface of the U-shaped testing frame. A traction unit is slidably connected in both sliding grooves, and a tensile unit is fixedly installed in the middle of the lower end of the traction unit. A fixing unit corresponding to the position of the tensile unit is fixedly installed on the upper end of the base plate.

[0006] The traction unit includes a forward and reverse motor and a traction plate. The forward and reverse motor is fixedly installed on the upper end of the U-shaped detection frame. A ball screw is fixedly connected to the output end of the forward and reverse motor. The ball screw is movably installed in a slide groove on one side. Sliders are fixedly connected to both ends of the traction plate. The two sliders are slidably connected in the slide grooves on both sides, and the slider on one side is threadedly connected to the ball screw.

[0007] Preferably, the stretching unit includes a stand, a tension sensor is fixedly connected to the upper middle part of the stand, the tension sensor is fixedly installed at the lower end of the traction plate, and a first take-up reel and a first locking component are fixedly installed on the stand.

[0008] By adopting the above technical solution: by setting up a tension sensor to realize real-time monitoring of the force during the stretching process of the optical cable, the detection accuracy is improved. At the same time, a No. 1 winding reel and a No. 1 locking component are integrated on the same frame, so that one end of the optical cable can be wound and then clamped, which enhances the stability and reliability of the fixation.

[0009] Preferably, the first locking component includes a support plate and a positioning plate, both of which are fixedly connected to the upright frame. An adjusting screw is threaded through the middle of the support plate, and one end of the adjusting screw is movably connected to a clamping plate via a bearing. The clamping plate is slidably connected to the upright frame and is positioned opposite to the positioning plate.

[0010] By adopting the above technical solution, the clamping plate is moved towards the positioning plate by rotating the adjusting screw, thereby realizing the clamping operation of the optical cable end. It has the characteristics of compact structure and convenient clamping, and the clamping force can be precisely controlled by adjusting the screw, which is suitable for the clamping needs of optical cables of different diameters.

[0011] Preferably, two guide rods are fixedly connected to the clamping plate. The two guide rods are symmetrically distributed on both sides of the adjusting screw, and both guide rods are slidably connected to the support plate.

[0012] By adopting the above technical solution, the guide rod provides a guiding function for the clamping plate, ensuring that it moves in a straight line during the clamping process, avoiding deviation or jamming, improving the stability and repeatability of clamping, and enhancing the rigidity and durability of the overall structure.

[0013] Preferably, the opposite ends of the positioning plate and the clamping plate are integrally formed with anti-slip ridges.

[0014] By adopting the above technical solution, the anti-slip convex strip design increases the friction between the clamping surface and the optical cable, effectively preventing the optical cable from slipping or loosening during the stretching process, further improving the clamping firmness, and is especially suitable for high-strength tensile testing environments.

[0015] Preferably, the fixing unit includes a fixing plate, which is fixedly installed on the upper end of the base plate. A second locking element and a second winding reel are fixedly connected to the fixing plate. The second winding reel has the same structure as the first winding reel and their positions correspond to each other.

[0016] By adopting the above technical solution, a fixed unit structure symmetrically arranged with the tensioning unit is used to achieve a double fixing method of winding and clamping at the other end of the optical cable, ensuring that the forces at both ends are consistent and improving the symmetry of the detection process and the accuracy of the data.

[0017] Preferably, the structure of the second locking member is the same as that of the first locking member, and the position of the second locking member corresponds to the position of the first locking member.

[0018] By adopting the above technical solution, the consistency of the clamping structure at both ends of the optical cable is achieved, which facilitates unified operation and maintenance. At the same time, it ensures that the force on both ends of the optical cable is balanced during the stretching process, reduces the detection error caused by clamping differences, and improves the overall applicability and stability of the device.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up a traction unit, including forward and reverse motors, ball screws, and traction plates, smooth driving and precise control of the optical cable stretching process are achieved. The forward and reverse motors drive the ball screws to rotate, which in turn drives the traction plate to move linearly along the slide, thereby causing the stretching unit to move in the opposite direction relative to the fixed unit. This ensures that the optical cable is subjected to a uniform and stable tensile force. This design not only improves the stability and controllability of the stretching process, but also effectively avoids the impact and off-center load problems that are prone to occur in traditional manual or hydraulic methods, and significantly improves the accuracy and repeatability of the test.

[0021] 2. By setting up take-up reels and locking mechanisms on the tensioning and fixing units respectively, the first take-up reel and the first locking mechanism work together to wind and clamp the end of the optical cable, while the second take-up reel and the second locking mechanism are used to fix the other end of the optical cable, achieving synchronous clamping at both ends. The locking mechanism uses an adjusting screw to drive the clamping plate to move, and is supplemented by a guide rod and anti-slip convex strips to enhance friction, ensuring a firm and reliable clamping and preventing the optical cable from slipping or falling off during the tensioning process. This structure greatly enhances the stability of the optical cable fixation, improves the safety and effectiveness of the test, and is especially suitable for optical cable mechanical performance testing scenarios with high strength and high precision requirements.

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] A fiber optic cable tensile testing device includes a base plate 1, a U-shaped testing frame 2 fixedly installed on the upper end of the base plate 1, a controller 3 fixedly installed on the U-shaped testing frame 2, and sliding grooves 4 on both the left and right sides of the inner surface of the U-shaped testing frame 2. A traction unit 5 is slidably connected in the two sliding grooves 4, a tensile unit 6 is fixedly installed in the middle of the lower end of the traction unit 5, and a fixing unit 7 corresponding to the position of the tensile unit 6 is fixedly installed on the upper end of the base plate 1.

[0032] In this embodiment, the traction unit 5 includes a forward and reverse motor 51 and a traction plate 53. The forward and reverse motor 51 is fixedly installed on the upper end of the U-shaped detection frame 2. The output end of the forward and reverse motor 51 is fixedly connected to a ball screw 52. The ball screw 52 is movably installed in a slide groove 4 on one side. Both ends of the traction plate 53 are fixedly connected to sliders 54. The two sliders 54 are slidably connected in the slide grooves 4 on both sides, and the slider 54 on one side is threadedly connected to the ball screw 52. The tension unit 6 includes a stand 61. A tension sensor 62 is fixedly connected to the middle of the upper end of the stand 61. The tension sensor 62 is fixedly installed on the lower end of the traction plate 53. A first take-up reel 63 and a first locking member 64 are fixedly installed on the stand 61. The fixing unit 7 includes a fixing plate 71. The fixing plate 71 is fixedly installed on the upper end of the base plate 1. A second locking member 72 and a second take-up reel 73 are fixedly connected to the fixing plate 71. The second take-up reel 73 has the same structure as the first take-up reel 63 and their positions correspond.

[0033] Through the above scheme: the forward and reverse motors 51 in the traction unit 5 drive the ball screw 52 to rotate. The ball screw 52 is threadedly connected to the slider 54 on one side, which drives the traction plate 53 to move linearly along the sliding grooves 4 on both sides of the inner surface of the U-shaped detection frame 2. Since the traction plate 53 has sliders 54 at both ends and slides with the sliding grooves 4 on both sides, the entire traction process is stable and reliable, and there will be no deviation or shaking. As the traction plate 53 moves, the upright 61 fixed at its lower end and the entire tension unit 6 move accordingly. At this time, the tension sensor 62 monitors the tension value applied to the optical cable in real time during the tensioning process and feeds the data back to the controller 3 to realize the precise control and measurement of the tension force. When the tension unit 6 moves away from the fixed unit 7, the optical cable is subjected to tension. Its mechanical properties, such as tensile strength and elongation, can be analyzed through the data collected by the tension sensor 62. The tension sensor 62 is a known existing technology in the market, and its internal structure and working principle will not be described in detail here.

[0034] In this embodiment, the first locking component 64 includes a support plate 641 and a positioning plate 644. Both the support plate 641 and the positioning plate 644 are fixedly connected to the upright 61. An adjusting screw 642 is threadedly connected to the middle of the support plate 641. One end of the adjusting screw 642 is movably connected to a clamping plate 643 via a bearing. The clamping plate 643 is slidably connected to the upright 61 and is positioned opposite to the positioning plate 644. Two guide rods 645 are fixedly connected to the clamping plate 643. The two guide rods 645 are symmetrically distributed on both sides of the adjusting screw 642. Both guide rods 645 are slidably connected to the support plate 641. The opposing ends of the positioning plate 644 and the clamping plate 643 are integrally formed with anti-slip protrusions 6441. The structure of the second locking component 72 is the same as that of the first locking component 64, and the position of the second locking component 72 corresponds to the position of the first locking component 64.

[0035] The above scheme involves placing the optical cable to be tested above the base plate 1 and fixing both ends. One end of the optical cable is wound around the first take-up reel 63 in the tensioning unit 6 to prevent the optical cable from loosening or slipping during the tensioning process. Then, the end is inserted into the clamping area of ​​the first locking member 64, and the clamping plate 643 is moved along the guide rod 645 and pressed against the optical cable by rotating the adjusting screw 642. The anti-slip protrusion 6441 between the clamping plate 643 and the positioning plate 644 can enhance the friction and ensure that the optical cable is firmly clamped. Similarly, the other end of the optical cable is wound around the second take-up reel 73 on the fixing unit 7 in the same way and clamped in the second locking member 72, thereby achieving stable fixation of both ends of the optical cable.

[0036] It should be noted that this utility model is a fiber optic cable tensile testing device. When using this device, the fiber optic cable to be tested is first placed on the base plate 1, and both ends are fixed. One end of the cable is wound around the first take-up reel 63 in the tensile unit 6 to prevent the cable from loosening or slipping during the tensile process. Then, the end is inserted into the clamping area of ​​the first locking member 64, and the clamping plate 643 is moved along the guide rod 645 and pressed against the cable by rotating the adjusting screw 642. The anti-slip protrusions 6441 between the clamping plate 643 and the positioning plate 644 enhance the friction and ensure that the cable is firmly clamped. Similarly, the other end of the cable is wound around the second take-up reel 73 on the fixing unit 7 in the same way and clamped in the second locking member 72, thereby achieving stable fixation of both ends of the cable. After the installation and clamping of the cable are completed, the controller 3 is started to control the traction unit 5 to start running. Motor 51 drives ball screw 52 to rotate. Ball screw 52 is threadedly connected to slider 54 on one side, driving traction plate 53 to move linearly along the sliding grooves 4 on both sides of the inner surface of U-shaped detection frame 2. Since sliders 54 are provided at both ends of traction plate 53 and slide in cooperation with sliding grooves 4 on both sides, the entire traction process is stable and reliable, without deviation or shaking. As traction plate 53 moves, the upright 61 fixed at its lower end and the entire tension unit 6 move accordingly. At this time, tension sensor 62 monitors the tension value applied to the optical cable in real time during the tensioning process and feeds the data back to controller 3 to achieve precise control and measurement of tension force. When tension unit 6 moves away from fixed unit 7, optical cable is subjected to tension. Its mechanical properties, such as tensile strength and elongation, can be analyzed through the data collected by tension sensor 62. The entire tensioning process is uniformly coordinated and controlled by controller 3, which can set parameters such as tensioning speed and maximum tension value to achieve automated detection. After the test is completed, the forward and reverse motor 51 reverses, driving the traction plate 53 to reset, releasing the tension, and then manually loosening the locking device, so that a new optical cable sample can be replaced for the next round of testing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
