Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber processing technology, specifically a cutting device for optical fiber processing. Background Technology
[0002] Optical fiber cable is a type of communication cable composed of two or more glass or plastic optical fiber cores. These fiber cores are located within a protective cladding and covered by a plastic PCV outer sheath. Signal transmission along the internal optical fibers typically uses infrared light. Optical fiber communication is one of the important methods of modern information transmission, characterized by large capacity, long relay distance, good confidentiality, immunity to electromagnetic interference, and copper saving. During processing, optical fiber cables require a cutting device to cut them. Optical fiber cutting equipment is widely used in the field of optical cable processing. However, existing optical fiber cutting equipment has certain drawbacks. Currently, optical fibers are mainly cut manually by operators, resulting in low work efficiency, low cutting accuracy, and difficulty in consistently cutting the fibers, easily producing burrs that affect the use of the optical fibers.
[0003] Chinese Patent No. CN214586096U discloses a cutting device for optical fiber processing, including a fixed base. Limiting blocks are fixedly installed on the upper surface of the fixed base near its upper and lower edges. A sheath groove is formed on the upper surface of the fixed base at the center position between the two limiting blocks. A movable cover plate is movably installed at the upper edge of the fixed base. A tool sliding shaft is fixedly installed inside the movable cover plate, and a movable rotating shaft is movably installed inside the movable cover plate above the tool sliding shaft. This cutting device for optical fiber processing can firmly hold the optical fiber sheath, increasing the stability of the optical fiber during cutting. Turning the adjustment knob allows the cutting tool to move within the tool groove. The position of the cutting tool can be observed using a scale groove, facilitating the determination of the optical fiber cutting length and ensuring cutting accuracy. This makes the optical fiber more stable during cutting and reduces the generation of burrs.
[0004] The existing technical solutions described above have the following drawbacks: when cutting optical fibers, it is necessary to first use a clamping pad to fix the optical fiber sheath, and then flip the movable cover plate downwards to drive the cutting tool downwards before the cutting tool can cut the optical fiber. This reduces the ease of use of the device. Furthermore, the optical fiber is not stabilized by additional fixing components during cutting, which makes it prone to shaking and affects the cutting accuracy. In view of the above, technical innovation is carried out on the basis of existing optical fiber cutting equipment. Utility Model Content

[0022] Please see Figures 1-4A cutting device for optical fiber processing includes a pressure plate 12, a first fixing plate 13 placed below the pressure plate 12, two sets of second guide posts 14 evenly fixed on the top of the first fixing plate 13, the top of the second guide posts 14 penetrating the top of the pressure plate 12 and connected to a connecting plate 17, a first spring 18 fixed between the connecting plate 17 and the pressure plate 12, the first spring 18 being located on the outer ring of the second guide posts 14, an internally threaded cross slider 19 slidably disposed inside the pressure plate 12, a cutting tool 15 fixedly disposed on the bottom left side of the internally threaded cross slider 19, and the bottom of the internally threaded cross slider 19... The right side is evenly provided with sliding grooves, and a third spring 28 is fixedly installed in each groove. A third guide post 24 is fixedly installed at the bottom of the third spring 28. A second fixing plate 16 is fixedly installed at the bottom of the two sets of third guide posts 24. A screw 27 is screwed into the internal threaded cross slider 19. A worm gear 26 is fixedly installed on the right side of the screw 27. A worm 22 is meshed at the top of the worm gear 26. A handwheel 23 is fixedly installed on the front side of the worm 22. By rotating the handwheel 23, the worm 22 is driven to rotate. The worm 22 drives the screw 27 to rotate through the worm gear 26. The screw 27 drives the internal threaded cross slider 19 to slide left and right. This causes the cutting tool 15 at the bottom of the internal thread cross slider 19 and the second fixing plate 16 to adjust their left and right positions. Two sets of through holes are evenly distributed on the top left side of the pressure plate 12, and the second guide post 14 is slidably disposed within these through holes. A cross groove is distributed through the top of the pressure plate 12, and the internal thread cross slider 19 is slidably disposed within the cross groove. The screw 27 is rotatably disposed within the cross groove. A groove is distributed on the top right side of the pressure plate 12, and the worm gear 26 and worm 22 are rotatably disposed within the groove. The right side of the screw 27 passes through the cross groove and groove and connects to the worm gear 26. The front side of the worm 22 passes through the front of the pressure plate 12. The side is connected to the handwheel 23. The cutting tool 15 is located between the first fixed plate 13 and the second fixed plate 16. The bottom horizontal plane of the first fixed plate 13 and the second fixed plate 16 is lower than the bottom horizontal plane of the cutting tool 15. The top of the internal thread cross slider 19 is fixedly equipped with a pointer 2. The top of the pressure plate 12 is evenly provided with scale lines 21. The pointer 2 corresponds to the scale lines 21 and the cutting tool 15. When the internal thread cross slider 19 moves left and right, it will drive the pointer 2 to move synchronously. Through the cooperation of the pointer 2 and the scale lines 21, the worker can easily observe the movement position of the cutting tool 15.
[0023] A base 1 is placed below the pressure plate 12. A first guide post 11 is evenly fixedly arranged at the bottom of the pressure plate 12. A second spring 25 is fixedly arranged at the bottom of the first guide post 11. Guide holes are evenly opened at the top of the base 1. The second spring 25 is fixedly arranged in the guide hole. The first guide post 11 is slidably arranged in the guide hole. An optical fiber groove 31 is opened at the top of the base 1. A sheath groove 3 is opened through the left side of the optical fiber groove 31. The sheath part of the optical fiber is placed in the sheath groove 3, and the optical fiber is placed in the optical fiber groove 31. A discharge groove 32 is opened through the right side of the optical fiber groove 31. A first fixing plate 13 is located above the sheath groove 3. A cutting tool 15 and a second fixing plate 16 are located above the optical fiber groove 31.
[0024] Working principle: By rotating the handwheel 23, the worm gear 22 is driven to rotate. The worm gear 22 drives the screw 27 to rotate through the worm wheel 26. The screw 27 drives the internal thread cross slider 19 to slide left and right, thereby driving the cutting tool 15 and the second fixed plate 16 at the bottom of the internal thread cross slider 19 to adjust their left and right positions. When the internal thread cross slider 19 moves left and right, it will drive the pointer 2 to move synchronously. Through the cooperation of the pointer 2 and the scale line 21, the worker can easily observe the movement position of the cutting tool 15.
[0025] The sheath portion of the optical fiber is placed in the sheath groove 3, and the optical fiber is placed in the optical fiber groove 31. The pressing plate 12 moves the first fixing plate 13, the cleaver 15, and the second fixing plate 16 downwards. Since the bottom horizontal plane of the first fixing plate 13 and the second fixing plate 16 is lower than the bottom horizontal plane of the cleaver 15, the first fixing plate 13 will contact the optical fiber sheath in the sheath groove 3, and the second fixing plate 16 will contact the optical fiber in the optical fiber groove 31. As the pressing plate 12 continues to move downwards, the first fixing plate 13 will stretch the first spring 18 through the second guide post 14 and the connecting plate 17. The rebound force of the first spring 18 then uses the first fixing plate 13 to press the optical fiber sheath. Similarly, the second fixing plate 16 will press the third spring 28 upward through the third guide post 24. The rebound force of the third spring 28 will make the second fixing plate 16 press and fix the optical fiber. In this way, when the cutting tool 15 cuts the optical fiber downward, the optical fiber and the optical fiber sheath are in a stable state of being pressed and fixed, thus ensuring the cutting accuracy of the optical fiber. After the cutting is completed, by releasing the pressure plate 12, the second spring 25 will use its own rebound force to drive the pressure plate 12 to move upward and reset through the first guide post 11. This will drive the first fixing plate 13, the cutting tool 15 and the second fixing plate 16 below the pressure plate 12 to move upward and reset. At this time, tilting the equipment to the right will allow the cut optical fiber to be discharged along the discharge chute 32.
