It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] See also Figure 1-5 The utility model provides a technical solution: an optical fiber polishing device, comprising a T-shaped plate 1, a motor 2 is fixedly installed on the surface of the T-shaped plate 1, and a polishing disc 3 is fixedly installed on the output end of the motor 2.
[0024] The specific arrangement and function of the buffer device 4 and the limit device 5 will be described in detail below.
[0025] In this embodiment: a buffer device 4 is provided on the surface of the T-shaped plate 1, and the buffer device 4 includes a bar frame 401, which is fixedly installed on the surface of the T-shaped plate 1, and a vertical rod 402 is fixedly installed between the inner walls of the upper and lower ends of the bar frame 401, and a sliding plate 403 is slidably connected to the surface of the vertical rod 402, and a horizontal plate 404 is fixedly installed on the side of the sliding plate 403, and a slot plate 405 is fixedly installed on the end of the horizontal plate 404 away from the sliding plate 403.
[0026] In this embodiment, the vertical rod 402 is provided to enable the sliding plate 403 to move.
[0027] Specifically, two electric telescopic rods 406 are fixedly installed on the surface of the horizontal strip board 404 , and fixed plates 407 are fixedly installed on the output ends of the two electric telescopic rods 406 , and a long strip board 408 is fixedly installed between the two fixed plates 407 .
[0028] In this embodiment, the arrangement of the electric telescopic rod 406 and the fixed plate 407 has the effect of driving the long strip plate 408 to move.
[0029] Specifically, a groove 409 is formed on the surface of the long plate 408, and two sliders 410 are slidably connected inside the groove 409, and a first spring 411 is fixedly installed between the two sliders 410. The first spring 411 has the effect of limiting the position of the slider 410 inside the groove 409.
[0030] Specifically, a hinge plate 412 is hingedly connected to one end of the slider 410 away from the groove 409 , and a pressing plate 413 is hingedly connected to one end of the hinge plate 412 away from the slider 410 . The setting of the pressing plate 413 has the effect of pressing and limiting the optical fiber inside the card slot plate 405 .
[0031] In this embodiment: a limit device 5 is provided on the side of the sliding plate 403, and the limit device 5 includes a strip groove 51, and the strip groove 51 is opened on the side of the sliding plate 403. A movable plate 52 is slidably connected inside the strip groove 51, and an insertion rod 53 is fixedly installed on the surface of the movable plate 52. A plurality of insertion holes 54 are evenly opened on the surface of the bar frame 401. When the optical fiber is limited, the sliding plate 52 is moved to move the moving plate 52 inside the strip groove 51. The movement of the moving plate 52 inside the strip groove 51 will squeeze the second spring 56, so that the second spring 56 is compressed. At the same time, the movement of the moving plate 52 inside the strip groove 51 also drives the insertion rod 53 to move. The insertion rod 53 moves to move itself out of the inside of the insertion hole 54. The insertion rod 53 and the insertion hole 54 are separated to make the sliding strip plate 403 lose the limit on the surface of the vertical rod 402. At this time, the sliding strip plate 403 can be moved. The movement of the sliding strip plate 403 drives the horizontal strip plate 404 to move. The movement of the horizontal strip plate 404 drives the card slot plate 405 to move. The optical fiber is driven to move. When the distance between the moving position of the optical fiber and the grinding disk 3 is appropriate, the moving plate 52 is released, and the resilience of the second spring 56 is used to reinsert the insertion rod 53 into the corresponding insertion hole 54 to fix the position of the sliding plate 403 on the surface of the vertical rod 402 at this time. Finally, the motor 2 is started, and the motor 2 starts to drive the grinding disk 3 to rotate. The grinding disk 3 rotates to complete the grinding operation of the optical fiber. Through the cooperation of the above structure, the distance between the optical fiber and the grinding disk 3 can be adjusted to avoid the wear of the grinding disk 3 after long-term use in the later stage, which will cause a large gap between the optical fiber and the grinding disk 3 and affect the grinding effect.
[0032] Specifically, a rectangular plate 55 is fixedly installed on the side of the sliding plate 403 , and a second spring 56 is fixedly installed between the rectangular plate 55 and the moving plate 52 .
[0033] In this embodiment, the second spring 56 is provided to limit the position of the moving plate 52 inside the strip groove 51 .
[0034] Working principle: by setting the buffer device 4, firstly, the optical fiber is embedded in the interior of the card slot plate 405, and then the electric telescopic rod 406 is started. The electric telescopic rod 406 is started to drive the fixed plate 407 to move, and the fixed plate 407 moves to drive the long plate 408 to move, and the long plate 408 moves to drive the squeezing plate 413 to move, and the squeezing plate 413 moves to squeeze the optical fiber and limit it in the interior of the card slot plate 405. At the same time, when squeezing the optical fiber, the squeezing plate 413 will be forced to move, and the squeezing plate 413 moves to drive the hinged plate 412 to move, and the hinged plate 412 moves to push the two sliders 410 to move away from each other in the groove 409. The two sliders 410 move away from each other in the groove 409, which will drive the first spring 411 to stretch. At this time, the resilience of the first spring 411 is used to buffer the squeezing force. Through the cooperation of the above structure, the optical fiber connector to be clamped is effectively protected to prevent damage caused by excessive squeezing force. When the optical fiber is limited, the sliding plate 52 is moved to move the moving plate 52 inside the strip groove 51. The movement of the moving plate 52 inside the strip groove 51 will squeeze the second spring 56, so that the second spring 56 is compressed. At the same time, the movement of the moving plate 52 inside the strip groove 51 also drives the insertion rod 53 to move. The insertion rod 53 moves to move itself out of the inside of the insertion hole 54. The insertion rod 53 and the insertion hole 54 are separated to make the sliding strip plate 403 lose the limit on the surface of the vertical rod 402. At this time, the sliding strip plate 403 can be moved. The movement of the sliding strip plate 403 drives the horizontal strip plate 404 to move. The movement of the horizontal strip plate 404 drives the card slot plate 405 to move. The optical fiber is driven to move. When the distance between the moving position of the optical fiber and the grinding disk 3 is appropriate, the moving plate 52 is released, and the resilience of the second spring 56 is used to reinsert the insertion rod 53 into the corresponding insertion hole 54 to fix the position of the sliding plate 403 on the surface of the vertical rod 402 at this time. Finally, the motor 2 is started, and the motor 2 starts to drive the grinding disk 3 to rotate. The grinding disk 3 rotates to complete the grinding operation of the optical fiber. Through the cooperation of the above structure, the distance between the optical fiber and the grinding disk 3 can be adjusted to avoid the wear of the grinding disk 3 after long-term use in the later stage, which will cause a large gap between the optical fiber and the grinding disk 3 and affect the grinding effect.
