Description

Technical Field

[0001] This application relates to the technical field of optical part processing, and more specifically, to a clamping fixture for end face processing of a long optical waveguide component. Background Art

[0002] A long optical waveguide component (such as an optical waveguide rod) is usually long and has a cross-section that is a regular quadrilateral, regular hexagon, regular octagon, etc., with a height ranging from 200 to 500 mm. For long optical components such as optical waveguide rods, it is generally required that all surfaces be polished, and the surface shape and parallelism requirements for the two end faces in the height direction are more stringent, and the perpendicularity between the two end faces and other large surfaces is also required. When processing the end faces of long optical components such as optical waveguide rods, due to the high height of the long optical waveguide component, it is difficult to clamp, and end face processing such as polishing is relatively difficult.

[0003] Please refer to Figure 5 , in the existing processing process, by photo-cementing two cuboids 12 made of the same material as the product on both sides of the long optical waveguide component 10 (optical waveguide rod) and processing them integrally with the cuboids 12, it is equivalent to increasing the polishing area of the end face (bottom surface), and the end face processing of the long optical waveguide component 10 (optical waveguide rod) is improved to some extent. However, although the existing method increases the polishing area, the overall center of gravity of the long optical waveguide component 10 is still very high, and someone needs to watch the polished end face at all times to prevent it from tipping over and damaging the product, resulting in problems of low stability and safety. Moreover, in the current solution, in the form of photo-cementing cuboids, the sides of the cuboids need to be prepared in advance, which takes a longer time and has relatively low efficiency.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0005] The purpose of this application is to provide a clamping fixture for end face processing of a long optical waveguide component, which solves the problems of low stability, low safety, and low processing efficiency in the end face processing of the existing long optical waveguide component.

[0006] To achieve the above purpose, the technical solution adopted in this application is:

[0007] This application provides a clamping fixture for end face processing of a long optical waveguide component, including:

[0008] A counterweight disk, the counterweight disk has opposite first and second surfaces, and a clamping hole is formed through the first and second surfaces of the counterweight disk;

[0009] A support member, the support member is arranged on the first surface of the counterweight disk, a clamping cavity is formed inside the support member, and the clamping cavity is communicated with the clamping hole to be used for accommodating the long optical waveguide component in the clamping cavity and making the end face to be processed of the long optical waveguide component protrude from the clamping hole out of the second surface;

[0010] The locking member is disposed on the support member and extends into the clamping cavity through adjustment to fix the long optical waveguide member.

[0011] In an alternative embodiment, the support member includes: a plurality of support frames, which are all disposed on the counterweight plate and distributed around the clamping hole to enclose the clamping cavity;

[0012] The locking member is disposed on at least one support frame.

[0013] In an alternative embodiment, the support frame includes: a transverse plate connected to the first surface of the counterweight plate;

[0014] A vertical plate perpendicularly connected to the transverse plate;

[0015] The vertical plates of the plurality of support frames are sequentially connected to enclose the clamping cavity.

[0016] In an alternative embodiment, a measurement window is provided on the vertical plate, and the measurement window communicates with the clamping cavity.

[0017] In an alternative embodiment, 4 support frames are provided, and the clamping cavity formed by connecting the 4 support frames is square;

[0018] The locking member is disposed on each support frame.

[0019] In an alternative embodiment, the locking member includes: a locking screw;

[0020] At least one threaded hole is provided on the support member;

[0021] The locking screw passes through the support member through the threaded hole and enters the clamping cavity by rotation.

[0022] In an alternative embodiment, a protective pad is provided on the inner wall of the clamping cavity, and the protective pad is located inside the locking screw.

[0023] In an alternative embodiment, a processing counterweight plate is provided on the second surface of the counterweight plate, and the end face of the processing counterweight plate is used for synchronous processing with the end face to be processed of the long optical waveguide member.

[0024] In an alternative embodiment, a plurality of processing counterweight plates are provided, and the plurality of processing counterweight plates are symmetrically distributed around the clamping hole.

[0025] In an alternative embodiment, the clamping tool further includes a protective member, and the protective member is disposed outside the edge of the end face to be processed of the long optical waveguide member.

[0026] The beneficial effects of a clamping tool for end - face machining of a long optical waveguide provided by this application are at least as follows: By providing a support on the counterweight disk, after placing the long optical waveguide in the clamping cavity of the support, the end - face to be machined of the long optical waveguide protrudes from the clamping hole, and then by adjusting the locking part, the long optical waveguide is fixed in the clamping cavity, realizing the clamping of the long optical waveguide, so that the end - face to be machined on the side exposed on the second surface can be stably machined. Since the counterweight disk is used to fix the long optical waveguide, during the machining process, the overall center of gravity of the long optical waveguide and the tooling is reduced. Since the overall center of gravity is closer to the end - face to be machined, the stability during the machining process is higher. And through the cooperation of the support and the locking part to fix the long optical waveguide, the long optical waveguide is stably fixed in the clamping cavity, preventing the problem of the long optical waveguide tipping during the machining process. When machining (polishing) the end - face, there is no need for a special person to watch, and the safety is higher. Only by adjusting the locking part can the fixing and loosening of the long optical waveguide be realized, and the disassembly and assembly are more convenient, improving the efficiency and avoiding the time - consuming problem caused by the need to prepare a cuboid and machine the optical glue surface when using the optical glue method.

[0037] Please refer to Figure 1 、 Figure 2, this embodiment provides a clamping tooling for end face machining of a long optical waveguide component, which is used to machine the end face of the long optical waveguide component 10. For the convenience of structural description, taking the machining of the optical waveguide rod 11 as an example for specific illustration, the optical waveguide rod 11 has four side faces and two upper and lower end faces, and the lower end face of the optical waveguide rod 11 needs to be polished. The clamping tooling of this embodiment mainly includes: a counterweight disk 100, a support member 200, and a locking member 300. The counterweight disk 100 is a disk, and its main function is to increase the weight of the tooling, reduce the overall center of gravity during the machining process, and make the machining process more stable. The counterweight disk 100 is machined into a disk using materials with a large specific gravity such as copper alloy or stainless steel, so as to effectively increase the weight of the counterweight disk 100 under the condition of limited volume. For the convenience of structural description, the direction towards the central axis of the disk is defined as the inner, and the direction away from the central axis of the disk is defined as the outer. The counterweight disk 100 has opposite first surface 101 and second surface 102, and the first surface 101 and the second surface 102 can be the upper surface and the lower surface respectively. A clamping hole 110 penetrating the upper and lower surfaces is formed on the counterweight disk 100. Since the lower end face of the cuboid optical waveguide rod 11 is machined, the clamping hole 110 can be a square hole so that the square optical waveguide rod 11 passes through the square clamping hole 110. The support member 200 is arranged on the upper surface of the counterweight disk 100 and extends a predetermined length in the up and down direction. A clamping cavity 210 is formed inside the support member 200, and the clamping cavity 210 is communicated with the clamping hole 110 to accommodate the optical waveguide rod 11 in the clamping cavity 210 and make the end face to be machined of the optical waveguide rod 11 protrude from the clamping hole 110 to the lower surface; since the support member 200 has a certain length in the up and down direction, the clamping cavity 210 extends a certain length in the up and down direction, and the upper end of the clamping cavity 210 is open, which is convenient for the optical waveguide rod 11 to be inserted into the support member 200 from the upper end of the clamping cavity 210 and protrude below through the clamping hole 110 on the counterweight disk 100. The locking member 300 is arranged on the support member 200 and extends into the clamping cavity 210 through adjustment to fix the optical waveguide rod 11, thereby clamping and fixing the optical waveguide rod 11. After the clamping tooling is set on the polishing machine, the polishing tool located below the counterweight disk 100 can polish the lower end face of the optical waveguide rod 11 protruding downward.

[0038] A clamping tool for end - face machining of a long optical waveguide component in this embodiment. By arranging a support member 200 on a counterweight disk 100, after placing an optical waveguide rod 11 in a clamping cavity 210 of the support member 200, the end - face to be machined of the optical waveguide rod 11 protrudes from a clamping hole 110. Then, by adjusting a locking member 300, the optical waveguide rod 11 is fixed in the clamping cavity 210, achieving the clamping of the optical waveguide rod 11, so that the end - face to be machined on one side of the second surface 102 is stably polished by a polishing tool below. Since the counterweight disk 100 is used to fix the optical waveguide rod 11, during the polishing process, the overall center of gravity of the optical waveguide rod 11 and the tool is lowered. Because the overall center of gravity is closer to the end - face to be machined, the stability during the polishing process is higher. And through the cooperation of the support member 200 and the locking member 300 to fix the optical waveguide rod 11, the optical waveguide rod 11 is stably fixed in the clamping cavity 210, preventing the problem of the optical waveguide rod 11 tipping during the polishing process. When polishing the end - face, it does not require a special person to watch, and the safety is higher. Only by adjusting the locking member 300 can the fixing and loosening of the optical waveguide rod 11 be achieved, making the disassembly and assembly more convenient, improving the efficiency, and avoiding the time - consuming problem caused by preparing a cuboid and machining a photo - adhesive surface when using the photo - adhesive method.

[0039] Please refer to Figure 1 、 Figure 2 . Further, the support member 200 of this embodiment specifically includes: a plurality of support frames 220. The plurality of support frames 220 are all arranged on the counterweight disk 100 and are distributed around the clamping hole 110 to enclose the clamping cavity 210. At least one support frame 220 is provided with a locking member 300. Using a plurality of support frames 220 fixed on the counterweight disk 100 to enclose the clamping cavity 210 is convenient for assembling the clamping cavity 210, and can resist the offset of the optical waveguide rod 11 in multiple directions, ensuring the safety during the polishing process. At least one locking member 300 is arranged thereon. Through the locking member 300, the optical waveguide rod 11 can be fixed on the inner wall of the clamping cavity 210, simplifying the clamping process and improving the polishing efficiency.

[0040] Please refer to Figure 1 、 Figure 2 . Further, 4 support frames 220 are provided in this embodiment. The clamping cavity 210 formed by connecting the 4 support frames 220 is square. By matching the square clamping cavity 210 with the four side surfaces of the optical waveguide rod 11, when each support frame 220 is provided with a locking member 300, the four side surfaces of the optical waveguide rod 11 are respectively abutted and limited by the locking members 300 on each side surface, so that the optical waveguide rod 11 is stably fixed in the clamping cavity 210, achieving a more stable clamping.

[0041] It is easy to think that according to the different shapes of the optical waveguide rod 11 (such as hexagon, octagon, etc.), the number of support frames 220 can be adjusted, and the technical effects of this solution can also be achieved.

[0042] Please refer to Figure 2 、 Figure 3 、 Figure 4 and further, the support frame 220 of this embodiment specifically includes: a horizontal plate 221 and a vertical plate 222. The horizontal plate 221 is connected to the upper surface of the counterweight plate 100 by screws. The horizontal plate 221 is in a horizontal state on the upper surface of the counterweight plate 100. The vertical plate 222 is vertically connected to the horizontal plate 221. The vertical plate 222 extends a certain length in the up and down direction, so that the height of the support frame 220 is less than the height of the optical fiber rod 11 and can be greater than half of the height of the optical fiber rod 11. A counterbore is opened at the lower end of the inner surface of the vertical plate 222 and is fixed by being connected to the horizontal plate 221 by screws.

[0043] Please refer to Figure 2 、 Figure 3 and further, to improve the structural stability, the vertical plates 222 of multiple support frames 220 are sequentially connected to enclose a clamping cavity 210. In a specific structure, through holes are opened at the edges of the inner walls of the vertical plates 222 of one support frame 220 among adjacent support frames 220, and screw holes are opened on the side surfaces (the side surfaces adjacent to the inner wall surfaces) of the vertical plates 222 of the other support frame 220. Then, an M6 screw 223 passes through the through hole of one vertical plate 222 and is connected to the screw hole of the other vertical plate 222, so as to realize the fixed connection between adjacent support frames 220. Since the vertical plates 222 are relatively high in the up and down direction, at least 2 M6 screws 223 are spaced in the up and down directions, so that the structure of the entire support member 200 is more stable.

[0044] Please refer to Figure 2 、 Figure 4 and further, a measurement window 230 is opened on the vertical plate 222 of this embodiment. The measurement window 230 communicates with the clamping cavity 210. The detection device measures the side surface (side elevation) of the optical fiber rod 11 from the measurement window 230. Through the measurement window 230, the perpendicularity between the four side surfaces of the optical fiber rod 11 and the bottom surface polished and ground for the optical fiber rod 11 can be detected during the processing, so as to adjust the processing parameters, thus ensuring the processing quality and ensuring good perpendicularity between the polished and ground bottom surface and the side surface of the optical fiber rod 11.

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 4, Further, the locking member 300 of this embodiment specifically includes a locking screw 310. A threaded hole is provided on the support member 200, and the locking screw 310 is passed through the support member 200 through the threaded hole and enters the clamping cavity 210 by rotation. Using the locking screw 310 as the locking member 300, the locking and loosening of the optical fiber rod 11 can be achieved by screwing the locking screw 310. The structure is simple and convenient for disassembly. The locking screw 310 in this embodiment can be an M12 fastening screw. The optical fiber rod 11 can be pressed against the inner wall of the clamping cavity 210 by the M12 fastening screw on one vertical plate 222 to achieve fixation. Or M12 fastening screws can be provided on all the vertical plates 222, so that the four sides of the optical fiber rod 11 can be pressed tightly, making it not easy to loosen and achieving a more stable clamping.

[0046] Please refer to Figure 3 、 Figure 4 , Further, a protective pad 320 is provided on the inner wall of the clamping cavity 210 in this embodiment, and the protective pad 320 is located inside the locking screw 310. When the M12 fastening screw moves towards the inside of the clamping cavity 210 by rotation, the inner end face of the M12 fastening screw abuts against the protective pad, and the optical fiber rod 11 inside the clamping cavity 210 is fixed and pressed through the protective pad, so as to protect the product from being scratched or bruised.

[0047] Please refer to Figure 2 、 Figure 4 , Further, a processing matching plate 120 is provided on the lower surface of the counterweight plate 100 in this embodiment, and the end face of the processing matching plate 120 is used for synchronous processing with the end face to be processed of the optical fiber rod 11. By connecting the processing matching plate 120 to the lower surface of the counterweight plate 100, the material of the processing matching plate 120 is the same as that of the optical fiber rod 11, and the optical fiber rod 11 is processed with frosting and polishing together. This is equivalent to increasing the polishing area of the optical fiber rod 11, making the surface shape of the product better and ensuring the quality requirements of the polished lower end face of the optical fiber rod 11.

[0048] Further, there are multiple processing matching plates 120, and the multiple processing matching plates 120 are symmetrically distributed around the clamping hole 110. The clamping hole 110 is located at the center of the lower surface of the counterweight plate 100. By adopting the symmetric distribution method, the pressure applied to the lower end face of the optical fiber rod 11 in the middle during the polishing process is more uniform, so that a better polishing effect can be obtained and the surface shape quality of the product can be better guaranteed.

[0049] Further, a plurality of mounting grooves 121 are provided on the lower surface of the counterweight disk 100 around the clamping hole 110. The machining disk 120 is clamped in the mounting groove 121 and fixed by bonding. The position of the machining disk 120 is fixed through the mounting groove 121, realizing the rapid positioning of the installation of the machining disk 120, improving the installation efficiency, and ensuring the symmetry of a plurality of machining disks 120 well after installation, which is more conducive to the use of the tooling.

[0050] Please refer to Figure 2 , Figure 4 , further, the clamping tooling in this embodiment further includes a protection member 400, and the protection member 400 is arranged outside the edge of the end surface to be machined of the optical fiber preform 11. The protection member 400 is made of protective glass. The protective glass is in the form of a long glass strip, and is connected to the four side edges of the lower end surface of the optical fiber preform 11 through the glass strip, so as to protect the outer edge of the lower end surface and prevent the outer edge of the lower end surface from chipping during the machining process.

[0051] In summary, a clamping tooling for end face machining of long optical waveguide components provided by the present application realizes the end face machining of long optical waveguide component products, improves the machining stability and safety; and is convenient for disassembly and assembly, improving the machining efficiency.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
