Description

Technical Field

[0001] This invention belongs to the field of cutting tool technology, specifically relating to a large-diameter quartz fiber optic cutting tool. Background Technology

[0002] Currently, there is no dedicated cutting tool for large-diameter quartz optical fibers. Cutting or shearing them with ordinary tools generally results in rough or damaged end faces. Then, multiple polishing processes are performed using sandpaper or grinding discs of different grits to achieve better light transmittance. This process is complex, time-consuming, and can take several minutes to complete the cutting and polishing of a single fiber. It is costly and results in poor light transmittance. To address these issues, we propose a new cutting tool for large-diameter quartz optical fibers to improve efficiency, save time and labor, and reduce production costs for enterprises. Summary of the Invention

The tool body is mounted on the tool retainer, and the surface of the tool retainer has a receiving cavity for mounting the tool body. The tool retainer is slidably connected to the inner cavity of the tool housing, and a limiting component is provided between the surface of the tool retainer and the inner cavity of the tool housing. The tool body and the tool retainer are fixed together by a mounting component. An elastic connecting component is provided between the bottom of the tool retainer and the bottom of the inner cavity of the tool housing, and the tool retainer presses the tool body against the surface of the quartz fiber through the elastic connecting component. A clamping force adjusting component is also provided between the bottom of the tool retainer and the tool housing. A through hole for inserting the quartz fiber is provided on one side of the tool housing.

[0005] Preferably, the mounting assembly includes a mounting hole formed on the surface of the tool body, with a mounting rod slidably inserted into the inner cavity of the mounting hole; and a threaded hole formed on the inner wall of the receiving cavity, with one end of the mounting rod passing through the mounting hole and extending into the inner cavity of the receiving cavity and threadedly connected to the inner wall of the threaded hole.

[0006] Preferably, the limiting component includes limiting rods fixedly installed on both sides of the inner cavity of the tool housing; and a limiting groove formed on the surface of the tool holder, the limiting groove being adapted to the limiting rods, and the inner wall of the limiting groove being slidably connected to the surface of the limiting rods.

[0007] Preferably, the elastic connection assembly includes a compression spring disposed between the tool holder and the tool housing; and connecting blocks installed at the upper and lower ends of the compression spring. The bottom of the tool holder and the bottom of the inner cavity of the tool housing are both provided with connecting grooves adapted to the connecting blocks, and the surface of the connecting blocks is engaged with the inner wall of the connecting grooves.

[0008] Preferably, the clamping force adjusting assembly includes an adjusting screw hole formed at the bottom of the tool holder, an adjusting screw rod threadedly connected to the inner cavity of the adjusting screw hole, the bottom end of the adjusting screw rod passing through the adjusting screw hole and extending to the outside of the adjusting screw hole; and an adjusting rod installed at the bottom end of the adjusting screw rod, the bottom end of the adjusting rod passing through the tool housing and extending to the outside of the tool housing, and a knob fixedly installed thereon, the top of the knob being in contact with the bottom of the tool housing.

[0009] Preferably, the bottom of the tool housing is provided with a sliding hole adapted to the adjusting rod, and the surface of the adjusting rod is slidably connected to the inner wall of the sliding hole.

[0010] Preferably, the tool housing includes a first housing and a second housing arranged symmetrically; and a locking assembly for mounting the first housing and the second housing together.

[0011] Preferably, the locking assembly includes a locking hole on one side of the second housing; and a locking rod on one side of the first housing, the locking rod being disposed corresponding to the locking hole, and one end of the locking rod penetrating the first housing and extending to the outside of the first housing and being threadedly connected to the inner wall of the locking hole.

[0012] Preferably, the surface of the first housing has a countersunk hole adapted to the locking rod, and one end of the locking rod is hidden in the inner cavity of the countersunk hole.

[0013] Technical effects and advantages of the present invention: The large-diameter quartz fiber optic cutting tool proposed in this invention has the following advantages compared with the prior art: 1. This invention features a modular design, which facilitates assembly and maintenance. In use, press the cutter retainer, insert the large-diameter quartz fiber through the back hole of the cutter housing to the desired depth, gently loosen the cutter retainer, allowing the cutter to elastically hold the quartz fiber in place, then rotate the cutter around the quartz fiber 2-3 times, remove the cutter, and gently break the fiber to complete the cutting of the large-diameter quartz fiber. This invention has high cutting efficiency, completing the cutting in one pass through a circumferential cutting method, resulting in a smooth and complete end face without the need for subsequent polishing. The light transmittance of the fiber end face is significantly improved. 2. The present invention, through the setting of the mounting component, can install and fix the cutter body in the receiving cavity of the cutter holder. Furthermore, through the setting of the mounting component, it is also convenient to rotate the operating angle of the cutter body when a certain part of the cutting edge of the cutter body is severely worn, so that the severely worn cutting edge of the cutter body can be rotated to the side, and the sharper cutting edge can be used to cut the quartz optical fiber. 3. The present invention can elastically connect the tool holder and the tool housing by setting the elastic connection component. After the quartz optical fiber is inserted into the through hole, the compression spring can elastically press the cutting edge of the tool body against the surface of the quartz optical fiber, so that the quartz optical fiber can be effectively circumferentially cut when the tool is rotated. 4. By setting up a clamping force adjustment component, the clamping force between the cutter body and the quartz optical fiber can be adjusted. When the clamping force is too large, the user can rotate the adjusting screw into the inner cavity of the adjusting screw hole, thereby reducing the total length of the adjusting rod and adjusting screw exposed outside the adjusting screw hole. As a result, when the cutter retainer is reset upward, the top of the knob is in contact with the bottom of the cutter housing as soon as the cutter body just touches the surface of the quartz optical fiber, thus preventing the clamping force applied by the cutter body to the quartz optical fiber from being too large.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This invention is applied to the cutting of large-diameter special quartz optical fibers (including but not limited to large-diameter quartz optical fibers used in sunlight transmission systems, lasers, and other fields), ensuring that the cut surface of the optical fiber is complete, smooth, and has high light transmittance.

[0018] This invention provides, for example Figures 1-5 The large-diameter quartz fiber optic cutting tool shown includes a tool housing 1, a tool body 2, and a tool holder 3.

[0019] The tool housing 1 includes a first housing 19 and a second housing 20 arranged symmetrically; and a locking assembly for mounting the first housing 19 and the second housing 20 together. The locking assembly includes a locking hole 21 opened on one side of the second housing 20; and a locking rod 22 provided on one side of the first housing 19. The locking rod 22 is arranged correspondingly to the locking hole 21, and one end of the locking rod 22 passes through the first housing 19 and extends to the outside of the first housing 19 and is threadedly connected to the inner wall of the locking hole 21.

[0020] In this embodiment, the cutter housing 1 is a split design, which facilitates the assembly of the cutting cutter. By setting the locking component, the first housing 19 and the second housing 20 can be installed and fixed together. After the first housing 19 and the second housing 20 are closed together, the user can tighten the locking rod 22 to lock the first housing 19 and the second housing 20 together.

[0021] The surface of the first housing 19 is provided with a countersunk hole 23 that is adapted to the locking rod 22. One end of the locking rod 22 is hidden in the inner cavity of the countersunk hole 23. By setting the countersunk hole 23, one end of the locking rod 22 will be hidden in the inner cavity of the countersunk hole 23 when it is tightened, which can improve the flatness of the surface of the first housing 19.

[0022] The tool body 2 is mounted on the tool holder 3. The surface of the tool holder 3 is provided with a receiving cavity 4 for mounting the tool body 2. The receiving cavity 4 provides mounting space for the tool body 2.

[0023] In this embodiment, the surface of the tool holder 3 is adapted to the inner wall of the tool housing 1, and the tool holder 3 has an opening at the top for the tool body 2 to contact the surface of the quartz optical fiber.

[0024] The tool body 2 and the tool holder 3 are fixed together by a mounting assembly. The mounting assembly includes a mounting hole 6 on the surface of the tool body 2, and a mounting rod 7 is slidably inserted into the inner cavity of the mounting hole 6; and a threaded hole 8 on the inner wall of the receiving cavity 4. One end of the mounting rod 7 passes through the mounting hole 6 and extends into the inner cavity of the receiving cavity 4 and is threaded to the inner wall of the threaded hole 8.

[0025] By setting up the mounting components, the tool body 2 can be installed and fixed in the receiving cavity 4 on the surface of the tool holder 3. During installation, the user can place the tool body 2 in the inner cavity of the receiving cavity 4 and align the mounting hole 6 on the tool body 2 with the threaded hole 8 on the inner wall of the receiving cavity 4. Then, the user can tighten the mounting rod 7 so that one end of the mounting rod 7 passes through the mounting hole 6 and extends into the inner cavity of the receiving cavity 4 and is threaded to the inner wall of the threaded hole 8, thereby fixing the tool body 2 in its position.

[0026] It is worth noting that after the cutter body 2 is installed inside the receiving cavity 4 and used for a long time, the cutting edge of the cutter body 2 will be significantly worn, making the cutting edge of the cutter body 2 less sharp. At this time, the user can loosen the mounting rod 7 and rotate the cutter body 2 to rotate the worn cutting edge of the cutter body 2 away from the opening at the top of the cutter retainer 3. Then the user can tighten the mounting rod 7 again to lock and fix the use position of the cutter body 2.

[0027] The tool holder 3 is slidably connected to the inner cavity of the tool housing 1, and a limiting component is provided between the surface of the tool holder 3 and the inner cavity of the tool housing 1. The limiting component includes a limiting rod 9 fixedly installed on both sides of the inner cavity of the tool housing 1; and a limiting groove 10 opened on the surface of the tool holder 3. The limiting groove 10 is adapted to the limiting rod 9, and the inner wall of the limiting groove 10 is slidably connected to the surface of the limiting rod 9.

[0028] By setting the limiting component, the stability of the tool holder 3 moving in the inner cavity of the tool housing 1 can be improved, preventing the tool holder 3 from falling out of the inner cavity of the tool housing 1. At the same time, it can also prevent the tool holder 3 from shifting during movement, causing its surface to get stuck with the inner wall of the tool housing 1. When the tool holder 3 moves, it will cause the limiting groove 10 on its surface to slide on the surface of the limiting rod 9.

[0029] An elastic connecting component is provided between the bottom of the tool holder 3 and the bottom of the inner cavity of the tool housing 1. The tool holder 3 uses the elastic connecting component to press the tool body 2 against the surface of the quartz optical fiber. The elastic connecting component includes a compression spring 11 located between the tool holder 3 and the tool housing 1; and connecting blocks 12 installed at the upper and lower ends of the compression spring 11. Both the bottom of the tool holder 3 and the bottom of the inner cavity of the tool housing 1 are provided with connecting grooves 13 that are adapted to the connecting blocks 12. The surface of the connecting blocks 12 is engaged with the inner wall of the connecting grooves 13. By setting the elastic connection component, the tool holder 3 and the tool housing 1 can be elastically connected together. When the tool holder 3 is pulled down, the compression spring 11 will be squeezed. When the tool holder 3 is released, the reaction force generated by the compression spring 11 will push the tool holder 3 to reset. By using the connection block 12 and the connection groove 13 together, the compression spring 11 can be installed between the tool holder 3 and the tool housing 1.

[0030] The assembly process of the large-diameter quartz fiber optic cleaver in this embodiment is described in detail below: ① Installation of tool body 2: Secure the tool body 2 to the receiving cavity 4 on the surface of the tool holder 3 by tightening the mounting rod 7; ② Install the tool holder 3: After installing the tool body 2 on the tool holder 3, the user can place the tool holder 3 between the first housing 19 and the second housing 20, and then lock the first housing 19 and the second housing 20 together by the locking rod 22; ③ Install the elastic connection component: After installing the tool holder 3 into the inner cavity of the tool housing 1, the user can insert the connecting block 12 at the bottom of the compression spring 11 into the connecting groove 13 at the bottom of the inner cavity of the tool housing 1, and then squeeze the compression spring 11 to insert the connecting block 12 at the top of the compression spring 11 into the connecting groove 13 at the bottom of the tool holder 3.

[0031] A clamping force adjustment assembly is also provided between the bottom of the tool holder 3 and the tool housing 1. The clamping force adjustment assembly includes an adjustment screw hole 14 opened at the bottom of the tool holder 3, an adjustment screw 15 threadedly connected to the inner cavity of the adjustment screw hole 14, the bottom end of the adjustment screw 15 passing through the adjustment screw hole 14 and extending to the outside of the adjustment screw hole 14; and an adjustment rod 16 installed at the bottom end of the adjustment screw 15, the bottom end of the adjustment rod 16 passing through the tool housing 1 and extending to the outside of the tool housing 1, and a knob 17 fixedly installed thereon, the top of the knob 17 fitting against the bottom of the tool housing 1.

[0032] By setting the clamping force adjustment component, the clamping force of the tool body 2 on the quartz optical fiber can be adjusted. When it is necessary to reduce the clamping force applied by the tool body 2 on the quartz optical fiber, the user can turn the knob 17. The rotation of the knob 17 will drive the adjustment rod 16 to rotate, which in turn drives the adjustment screw 15 to rotate, so that the adjustment screw 15 is screwed into the adjustment screw hole 14 at the bottom of the tool holder 3, thereby reducing the total length of the adjustment screw 15 and the adjustment rod 16 exposed outside the adjustment screw hole 14, thereby moving the reset position of the tool holder 3 downward, so as to weaken the clamping force applied by the tool body 2 on the quartz optical fiber.

[0033] The bottom of the tool housing 1 is provided with a sliding hole 18 that is adapted to the adjusting rod 16. The surface of the adjusting rod 16 is slidably connected to the inner wall of the sliding hole 18. The sliding hole 18 provides space for the adjusting rod 16 to move, so that the top of the adjusting rod 16 can penetrate the tool housing 1 and extend into the inner cavity of the tool housing 1. In this embodiment, the surface of the knob 17 is also provided with an anti-slip groove to improve the friction of its surface.

[0034] A through hole 5 is provided on one side of the tool housing 1 for inserting a quartz optical fiber. The quartz optical fiber is inserted through the through hole 5 into the inner cavity of the tool housing 1 for cutting.

[0035] The following describes in detail the specific usage process of the large-diameter quartz fiber optic cleaver in this embodiment: ① Pull the tool holder 3 down to move the position of the tool body 2 downward. When the tool holder 3 is pulled down, the movement of the tool holder 3 will compress the spring 11. ② Insert the quartz fiber: Insert one end of the quartz fiber into the cutter housing 1 through the through hole 5. The user can insert it to an appropriate depth as needed. ③ Release the tool holder 3. At this time, the reaction force generated by the compression spring 11 will push the tool holder 3 to reset, so that the top cutting edge of the tool body 2 is pressed against the surface of the quartz optical fiber. ④ Rotate the cutter housing 1. The user can hold the quartz optical fiber and rotate the cutter housing 1 two to three times to drive the cutter body 2 to perform circumferential cutting on the quartz optical fiber. ⑤ After circumferential cutting, the user can repeat step ① and pull the quartz fiber out of the cutter housing 1, and then gently break the fiber to complete the cutting of the large-diameter quartz fiber.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
