[0002] According to CN217345008U, the utility model discloses a multi-angle optical fiber grinding and polishing device, specifically relating to the technical field of optical fiber grinding equipment. Most traditional optical fiber grinding and polishing is to install the optical fiber on the connection terminal and then manually grind and polish it. This method is not only time-consuming and laborious, but also easily causes scratches or cracks on the optical fiber section, resulting in the optical fiber being unusable. It includes a workbench and a mounting plate. One side of the workbench is rotatably inserted with a rotating shaft. A connecting plate is fixedly sleeved on the side of the rotating shaft away from the workbench. One end of the connecting plate is rotatably inserted with a connecting rod. One end of the connecting rod is fixedly provided with a grinding disc. One side of the grinding disc is fixedly provided with a grinding sheet. A motor is fixedly provided on the side of the workbench away from the fixed block. By starting the motor, the end of the output shaft of the motor drives the rotating shaft to rotate. The rotating shaft drives the connecting plate to rotate. The connecting plate drives the connecting rod to rotate. The connecting rod drives the grinding disc to rotate, so that the grinding sheet grinds and polishes the optical fiber section, thereby achieving the purpose of improving the grinding efficiency.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an auxiliary tool for optical fiber grinding includes a base 1. It is characterized in that a mounting disc 3 is arranged above the base 1, and a plurality of optical fiber fixing sockets 31 for fixing the end of the optical fiber are arranged in the middle of the mounting disc 3. A grinding mechanism 4 is installed between the base 1 and the mounting disc 3, and the grinding mechanism 4 is fixedly connected to the base 1 through a bracket 2; wherein, the grinding mechanism 4 includes a grinding disc 405 that abuts against the bottom of the mounting disc 3; and a driving component installed between the grinding disc 405 and the bracket 2, which is used to drive the grinding disc 405 to perform a compound motion while rotating around its own axis and revolving around the center of the bottom of the mounting disc 3 in a circular motion.

[0022] In this embodiment: Since the existing optical fiber grinding equipment uses a motor to drive the grinding disc to revolve, and the grinding disc itself does not have the function of self-rotation, when grinding and polishing the end face of the optical fiber, its motion grinding method is single. The revolving motion helps to change the contact point between the end face of the optical fiber and the grinding disc, but cannot ensure the uniformity of grinding. Therefore, in this solution, a grinding mechanism 4 is installed between the base 1 and the mounting disc 3, and the driving component in the grinding mechanism 4 is used to drive the grinding disc 405 to combine the revolving motion and the self-rotation motion to form a compound motion, which can not only change the contact trajectory between the end face of the optical fiber and the grinding disc, but also ensure the uniformity of grinding, thereby improving the grinding effect.

[0023] It should be noted that the optical fiber fixed socket 31 is adapted to the optical fiber connector. Before grinding, the optical fiber connector can be inserted and fixed on the optical fiber fixed socket 31, so that the end face of the optical fiber contacts the grinding disc 405 for grinding and polishing.

[0024] Please refer specifically to Figure 3 , the driving assembly includes a disc body 401 fixedly connected to the bracket 2. The disc body 401 is a disc-shaped structure with an upper opening and a hollow interior; an internal gear ring 402 provided at the open end of the disc body 401; a rotating arm 403 rotatably connected to the middle of the bottom end of the disc body 401. A gear 404 is rotatably connected to the free end of the rotating arm 403 through a bearing. The gear 404 meshes with the internal gear ring 402; and a motor 406 installed at the bottom of the disc body 401 for driving the rotating arm 403 to rotate relative to the disc body 401.

[0025] In this embodiment: When grinding is required, the motor 406 drives the rotating arm 403 to rotate. The rotating arm 403 drives the gear 404 to make a revolution. While the gear 404 is revolving, it meshes with the internal gear ring 402, forcing the gear 404 to rotate. Then, the grinding disc 405 rotates and revolves under the action of the gear 404 to improve the grinding effect.

[0026] It should be noted that before grinding, a grinding sandpaper needs to be pasted on the grinding disc 405, and at the same time, a grinding fluid is applied to improve the grinding effect.

[0027] Please refer specifically to Figure 1 and Figure 2 , the grinding disc 405 and the gear 404 are fixedly connected by bolts or welding; the center of the disc body 401 is directly below the center of the mounting disc 3.

[0028] In this embodiment: The grinding disc 405 and the gear 404 are convenient to disassemble and assemble, which is convenient for subsequent maintenance. The center of the disc body 401 corresponds to the center of the mounting disc 3 in the vertical position, so as to control the movement range of the grinding disc 405 to be outside the center of the mounting disc 3.

[0029] Please refer specifically to Figure 4, there are four groups of limiting components 5 provided between the mounting disc 3 and the bracket 2 for fixedly limiting the four corner ends of the mounting disc 3 on the bracket 2; the limiting component 5 includes a fixed seat 501 fixedly connected to the top of the bracket 2; two clamping members 502 rotatably connected to the mounting disc 3 through a shaft rod, the lower ends of the two clamping members 502 are cross-shaped respectively, and a shaft hole for the shaft rod to pass through is provided at the intersection between the two clamping members 502; a connecting plate 503 provided on the outer side of the clamping member 502 and integrally formed with the clamping member 502; a spring 504 provided between the connecting plate 503 and the fixed seat 501, the upper end of the spring 504 is fixedly connected to the connecting plate 503; the limiting component 5 further includes a clamping protrusion 505 integrally formed with the mounting disc 3, and the clamping protrusion 505 can be clamped and limited between the two clamping members 502; the clamping protrusion 505 is a cylindrical structure, and the inner arc dimensions of the two clamping members 502 are adapted to the clamping protrusion 505.

[0030] In this embodiment: Since the fixation and limitation of the mounting disc by the existing optical fiber grinding equipment are relatively cumbersome, the staff needs to spend more time fixing the mounting disc, thus delaying the grinding efficiency. Therefore, in this solution, four groups of limiting components 5 are provided between the mounting disc 3 and the bracket 2. By using the four groups of limiting components 5 to limit and fix the mounting disc 3, the mounting and dismounting of the mounting disc 3 are relatively convenient. The four corners of the mounting disc 3 can be fixed or disassembled simultaneously, without the need to fix or disassemble them one by one, thereby shortening the disassembly and assembly time of the mounting disc 3 and indirectly improving the work efficiency.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
