[0002] In related technologies, fiber optic arrays are common optical components, consisting of connectors and multiple fiber bodies, with one end of each fiber body fixedly connected to the connector. During processing, the ends of the connectors need to be ground. Existing grinding fixtures are mainly divided into general-purpose fixtures and special-purpose fixtures, both using clamping blocks for clamping and fixing. However, general-purpose fixtures, due to their need to adapt to various fiber optic arrays, lack specific positioning structures, resulting in poor clamping stability and easy displacement of the fiber optic array during grinding, affecting accuracy. While special-purpose fixtures can provide stable fixing for specific fiber optic arrays, they are only applicable to a single specification. Grinding different types of fiber optic arrays requires changing the fixture, increasing usage costs. Therefore, existing grinding fixtures cannot simultaneously meet the requirements of clamping stability, versatility, and low cost. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figure 7 In related technologies, fiber optic arrays are common optical components, consisting of a connector 310 and multiple fiber bodies 320, with one end of each fiber body 320 fixedly connected to the connector 310. During processing, the ends of the connector 310 need to be ground. Existing grinding fixtures are mainly divided into general-purpose fixtures and special-purpose fixtures, both of which use clamping blocks to clamp and fix the fiber.

[0023] Because general-purpose fixtures need to be adapted to various fiber arrays, they lack specific positioning structures, which makes it easy for the fiber arrays to slide and shift in the fixture. This results in poor clamping stability of the general-purpose fixtures, affecting grinding accuracy and hindering the improvement of yield. While specialized fixtures can provide a stable fixation effect for specific fiber arrays, they are only applicable to a single specification. Grinding different types of fiber arrays requires replacing the entire fixture, which not only increases the cost of use, but also takes a long time to redesign the entire specialized fixture, and cannot meet production needs.

[0024] Therefore, this utility model proposes a fiber array polishing fixture, which can improve the stability of clamping, be applicable to various specifications of fiber arrays, and reduce the cost of use.

[0025] Understandably, referring to Figures 1 to 4 ,as well as Figure 6 The fiber array polishing fixture of this utility model includes a fixture body 100 and a positioning seat 200. The fixture body 100 includes a mounting seat 110 and a fixing seat 120. The fixing seat 120 is fixedly connected to the mounting seat 110 and is threadedly connected to a first bolt 121. The first bolt 121 can move towards or away from the mounting seat 110. The positioning seat 200 is detachably connected to the mounting seat 110 and has a positioning groove 210. The shape of the positioning groove 210 matches the shape of the fiber array. The fiber array is installed in the positioning groove 210, and the first bolt 121 is used to press the fiber array into the positioning groove 210.

[0026] The fixing base 120 is fixedly connected to the mounting base 110, and the positioning base 200 is detachably connected to the mounting base 110. The positioning base 200 has a positioning groove 210, and the shape of the positioning groove 210 matches the shape of the fiber array. The fiber array is arranged in the positioning groove 210 so that the fiber array can be positioned in the fixing groove. Then, the first bolt 121 is driven to rotate in the fixing base 120, so that the first bolt 121 can move towards the mounting base 110. This allows the end of the first bolt 121 to push the fiber array to press it into the positioning groove 210, thereby fixing the position of the fiber array, preventing the position of the fiber array from shifting, and improving the stability of the clamping.

[0027] In addition, the positioning base 200 is detachably connected to the mounting base 110, and can be adapted to different specifications of fiber arrays by replacing different positioning bases 200, without having to replace the entire grinding fixture, which can improve the versatility of the grinding fixture and reduce the cost of use.

[0028] It should be noted that the positioning seat 200 can be connected to the mounting seat 110 by means of fasteners, snap-fit ​​connections, adhesives, magnetic attraction, etc., which makes it easy to assemble and disassemble the positioning seat 200. It can not only adapt to fiber optic arrays of different specifications, but also prevent the fiber optic array from shifting position, which helps to improve the grinding accuracy and yield.

[0029] Understandably, referring to Figure 1 and Figure 2The positioning seat 200 is fitted with a second bolt 220, which is threadedly connected to the mounting seat 110. The second bolt 220 passes through the positioning seat 200 and is threadedly connected to the mounting seat 110, facilitating the installation and removal of the positioning seat 200. Simply unscrewing the second bolt 220 from the mounting seat 110 allows the positioning seat 200 to be removed without the need for complex tools or cumbersome operations, enabling replacement of the positioning seat 200. The second bolt 220 is then tightened back into the mounting seat 110 to complete the replacement, improving the ease of installation and removal of the positioning seat 200 and contributing to increased production efficiency.

[0030] It should be noted that the number of second bolts 220 is set to multiple. The number of second bolts 220 increases the number of support points of the positioning seat 200, so that the positioning seat 200 can be stably placed on the mounting seat 110, thereby improving the connection reliability.

[0031] Understandably, referring to Figure 3 and Figure 4 The mounting base 120 has a groove 122, and a pressure block 123 is slidably connected to the groove 122. The side wall of the pressure block 123 has at least one flat surface, and the shape of the pressure block 123 matches the shape of the groove 122. The end of the first bolt 121 is rotatably connected to the pressure block 123, allowing the pressure block 123 to abut against the fiber optic array. The mounting base 120 has a groove 122, and the pressure block 123 is slidably connected within it. By providing at least one flat surface on the side wall of the pressure block 123 and matching the shape of the groove 122 to the pressure block 123, the sliding direction of the pressure block 123 is limited, preventing it from rotating within the groove 122. The rotatable connection between the end of the first bolt 121 and the pressure block 123 allows the first bolt 121 to push the pressure block 123 to slide stably along the length of the groove 122, preventing accidental rotation of the pressure block 123 and scratching the fiber optic array, thus improving the clamping reliability of the fiber optic array.

[0032] It should be noted that the pressing blocks 123 can be triangular prisms, quadrangular prisms, or other polygonal prisms, which will not be elaborated here.

[0033] Specifically, refer to Figure 3 and Figure 4The pressure block 123 has a connecting groove 124, and the end of the first bolt 121 is provided with a connecting part 125. The connecting part 125 is engaged in the connecting groove 124 and can rotate in the connecting groove 124. By setting the connecting part 125 to be engaged in the connecting groove 124 and the connecting groove 124 to be able to rotate in the connecting groove 124, the first bolt 121 can stably push the pressure block 123 to move in the sliding groove 122 when the first bolt 121 rotates in the fixed seat 120. This can effectively prevent the first bolt 121 from separating from the pressure block 123, ensure the stability of the clamping process, and improve the reliability of the grinding fixture.

[0034] Understandably, referring to Figure 1 , Figure 2 and Figure 6 Multiple fixing seats 120 and positioning seats 200 are provided, with the multiple positioning seats 200 arranged circumferentially along the mounting base 110. Each fixing seat 120 corresponds one-to-one with a positioning seat 200. By providing multiple fixing seats 120 and positioning seats 200, with each fixing seat 120 corresponding one-to-one with a positioning seat 200, the mounting base 110 can clamp multiple fiber arrays circumferentially. This makes the fixture structure more compact and rational, enabling multi-station clamping, which helps improve the polishing efficiency of the fiber arrays. Furthermore, it avoids mutual interference between multiple fiber arrays, ensuring that each fiber array receives stable and uniform clamping pressure, thereby improving polishing accuracy and consistency. Specifically, refer to Figure 2 and Figure 3 The number of positioning slots 210 is set to multiple, and the multiple positioning slots 210 are arranged in parallel and spaced on the positioning base 200. The multiple positioning slots 210 are arranged in parallel and spaced on the positioning base 200, so that one positioning base 200 can clamp multiple fiber arrays at the same time, making the grinding fixture structure more compact, and enabling the positioning of multiple fiber arrays at one time, thereby improving the grinding efficiency.

[0035] Specifically, refer to Figure 5 and Figure 6 The fixture body 100 also includes a positioning plate 130. A third bolt 131 passes through the mounting base 110 and is threadedly connected to the positioning plate 130. The positioning plate 130 can abut against the fiber array. The third bolt 131 passes through the mounting base 110 and is threadedly connected to the positioning plate 130. By rotating the third bolt 131, the positioning plate 130 can be driven to move closer to the mounting base 110, so that the positioning plate 130 can abut against the fiber array, so that multiple fiber arrays can be positioned on the positioning plate 130, and so that multiple fiber arrays can be positioned on the same plane, improving the polishing consistency of multiple fiber arrays.

[0036] It should be noted that multiple fiber arrays are arranged in multiple positioning slots 210 respectively. Then, the third bolt 131 is rotated to make the positioning plate 130 abut against the multiple fiber arrays, so that the fiber arrays slide in the positioning slots 210 to be positioned in the vertical direction. Then, the first bolt 121 is rotated to press the fiber arrays into the positioning slots 210 to accurately fix the position of the fiber arrays.

[0037] Understandably, referring to Figure 1 , Figure 6 and Figure 7 The fixture body 100 also includes a hook 140, which is detachably connected to the mounting base 110. Multiple support rods 141 are spaced circumferentially along the side wall of the hook 140, allowing the fiber array to abut against the support rods 141. The hook 140 is detachably connected to the mounting base 110, and the multiple support rods 141 are spaced circumferentially along the hook 140. The fiber body 320 can abut against the support rods 141, thereby supporting the fiber array, reducing positional movement of the fiber body 320 during polishing, and ensuring the fiber body 320 remains stable within the connector 310, reducing the possibility of loosening and improving polishing stability.

[0038] In addition, when the hook 140 is connected to the mounting base 110, it not only facilitates the transfer of the fiber polishing fixture but also makes it easy to place the fiber polishing fixture in the polishing machine, improving ease of use. When the hook 140 is removed from the mounting base 110, it avoids the installation position of the fiber array, facilitating the clamping and arrangement of the fiber array and improving ease of use.

[0039] It should be noted that the hook 140 can be connected to the mounting base 110 by means of fasteners, snap-fit ​​connections, adhesives, magnets, etc., which will not be described in detail here.

[0040] Specifically, refer to Figure 1 , Figure 6 and Figure 7 A limiting plate 142 is fixedly connected to the end of the support rod 141 away from the hook 140, and the fiber array can abut against the limiting plate 142. The limiting plate 142 is fixedly connected to the end of the support rod 141 away from the hook 140, which can prevent the fiber body 320 from moving axially along the support rod 141, prevent the fiber body 320 from deviating and falling off the support rod 141, and allow the end of the fiber body 320 away from the connector 310 to be away from the mounting base 110, preventing the fiber body 320 from falling onto the polishing machine and improving the reliability of polishing.

[0041] It should be noted that the end of the optical fiber body 320 away from the connector 310 can be wrapped around the support rod 141. By setting the limiting plate 142, the optical fiber body 320 can be prevented from sliding along the axial direction of the support rod 141, thereby preventing the end of the optical fiber body 320 away from the connector 310 from coming off the support rod 141 and improving the stability of the support.

[0042] Understandably, referring to Figure 1 and Figure 5 The fixture body 100 also includes a connecting frame 150. A fourth bolt 151 passes through the mounting base 110 and is threadedly connected to the connecting frame 150. The connecting frame 150 has multiple handle slots 152, which are spaced apart circumferentially along the connecting frame 150. The fourth bolt 151 passes through the mounting base 110 and is threadedly connected to the connecting frame 150, so that the connecting frame 150 can be fixedly mounted on the mounting base 110. By providing multiple handle slots 152 spaced apart circumferentially along the connecting frame 150, it is convenient for users to grip, thereby facilitating the application of force to move the grinding fixture and improving ease of use.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
