Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, and in particular to a bending device for testing optical cables. Background Art

[0002] Optical cables use optical fibers to convert signals into nearly a thousand times larger optical pulse signals during the transmission of light pulses, thus achieving long-distance, large-capacity data transmission. The optical fiber has strong anti-interference capabilities, large transmission capacity, and long transmission distance, which makes optical cables have incomparable advantages in data transmission. In the process of producing optical cables, it is often necessary to perform bending tests on the optical cables to evaluate the mechanical properties of the optical cables. However, since the traditional bending test method mainly relies on manual measurement, the optical cable is first formed into a loop by manual work, and then the two ends of the optical cable are pulled toward both sides to achieve the bending test of the optical cable. However, this measurement method not only has low data accuracy, but also low test efficiency. Therefore, we propose a bending device for optical cable testing to solve the above problems.

The limiting plate 312 is used to cooperate with the placement plate 311 to clamp and limit the optical cable 2.

[0021] like Figure 3 and Figure 4As shown, in another embodiment of the utility model, a first groove 301 is penetrated at the front end of the upper surface of the workbench 1, and the lower end of the movable block 305 is movably installed in the first groove 301, and the positive and negative screw rods 302 are movably penetrated and installed in the first groove 301. The rod bodies of the positive and negative screw rods 302 are movably penetrated and installed in the movable block 305 through threads, and a motor 303 is installed on one side of the workbench 1. One end of the positive and negative screw rods 302 movably penetrates the interior of the first groove 301 and is connected to the output end of the motor 303. Friction pads are respectively provided on the sides of the electric clamps 306 that are close to each other, and a scale 304 is installed on the upper surface of the workbench 1 and at one end close to the first groove 301. A guide groove 307 is provided in the middle of the upper surface of the workbench 1, and the lower end of the support frame 310 is movably installed in the guide groove 307. Guide rods 308 are fixedly installed at both ends of the interior, and the rod body of the guide rod 308 is movably installed in the interior of the support frame 310. The first spring 309 is respectively sleeved and installed on the outer side of the rod body of the guide rod 308 close to the movable block 305. The two ends of the first spring 309 are in contact with the support frame 310 and the guide groove 307. The side of the support frame 310 away from the first spring 309 is set as an arc surface, and the upper end of the support frame 310 and the side close to the limit plate 312 are provided with a second groove 313. A slider 314 is installed at one end of the limit plate 312, and the slider 314 is movably installed in the interior of the second groove 313. A pull rod 315 is movably installed in the upper end of the interior of the second groove 313. The lower end of the pull rod 315 and the slider 314 are fixedly connected, and the second spring 316 is sleeved and installed on the outer side of the rod body of the pull rod 315 located in the second groove 313.

[0022] The user forms the optical cable 2 into a ring shape, and then places one end of the optical cable 2 between the placement plate 311 and the limit plate 312, and then respectively engages and installs the two ends of the optical cable 2 inside the electric clamping plate 306, and the motor 303 can drive the positive and negative screw rods 302 to rotate, so that the positive and negative screw rods 302 can control the movable block 305 to move toward both sides respectively through the thread, and the movable block 305 can simultaneously pull the two ends of the optical cable 2 through the electric clamping plate 306 to perform a bending test, and then when the optical cable 2 is bent or broken, the motor 303 can stop moving, and then the user can calculate the mechanical properties of the optical cable 2 by the length of the two sides of the optical cable 2 pulled and the diameter of the optical cable 2 when it is ring-shaped;

[0023] By cooperating with the motor 303 and the forward and reverse screw rods 302, the movable block 305 can pull the two ends of the optical cable 2 with the same pulling force, thereby improving the accuracy of the overall bending test data. Then, when the movable block 305 moves to both sides, the user can use the scale 304 to know the length of the optical cable 2 pulled by the movable block 305 at any time, which is more convenient for the user to calculate.

[0024] The friction pad is used to increase the friction performance between the electric clamping plate 306 and the optical cable 2 to prevent the optical cable 2 from slipping during the pulling process;

[0025] When the user needs to install the optical cable 2, the user first pulls the slider 314 upward through the pull rod 315, allowing the slider 314 to squeeze the second spring 316, and also drives the limit plate 312 to move upward, and then the user can place one end of the optical cable 2 between the limit plate 312 and the placement plate 311. After the placement is completed, the user can release the pull rod 315, allowing the second spring 316 to push the slider 314, allowing the slider 314 to drive the limit plate 312 to cooperate with the placement plate 311 to clamp the optical cable 2, so that when the user forms the optical cable 2 into a ring and performs a pulling test, the optical cable 2 always maintains a ring shape through the push of the limit plate 312, which is more convenient for bending measurement.

[0026] When the movable block 305 pulls the two ends of the optical cable 2, one end of the optical cable 2 will gradually bend as the two ends of the optical cable 2 are pulled, and the support frame 310 will also be pulled to move the support frame 310 along the guide groove 307, so that the bending work of the optical cable 2 will not be hindered, and the bending position of the optical cable 2 can always be limited to ensure the accuracy of the overall data of the bending test;

[0027] The first spring 309 is used to push the support frame 310 to automatically reset in the later stage, waiting for the measurement of the next optical cable 2, which is simpler and more convenient.

[0028] The working principle of this bending device for optical cable testing:

[0029] When in use, the user first forms the optical cable 2 into a ring, and then places one end of the optical cable 2 between the placement plate 311 and the limit plate 312, and then respectively snaps the two ends of the optical cable 2 into place inside the electric clamp 306, and the motor 303 can drive the forward and reverse screw rods 302 to rotate, allowing the forward and reverse screw rods 302 to move toward both sides respectively through the threaded control movable block 305, and allowing the movable block 305 to simultaneously pull the two ends of the optical cable 2 through the electric clamp 306 to perform a bending test, and then when the optical cable 2 is bent or broken, the motor 303 can stop moving, and then the user can calculate the mechanical properties of the optical cable 2 through the length of the pull on both sides of the optical cable 2 and the diameter of the optical cable 2 when it is ring-shaped.

[0030] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
