Description

Technical Field

[0001] This utility model relates to the field of optical fiber polishing technology, and in particular to an adjustment mechanism for the polishing disc of an optical fiber polishing machine. Background Technology

[0002] Optical fiber is short for optical waveguide fiber, a type of fiber made of glass or plastic that can be used as a light transmission tool. Before installation and use, its tip needs to be polished. An optical fiber polishing machine is a device specifically used to polish various optical fiber connector products, mainly used to polish the end face of optical fiber ceramic ferrules, such as optical fiber patch cords, pigtails, bundled optical fibers, and PLC splitter heads. When polishing bare optical fibers, a polishing disc is used. Because bare optical fibers are small, they need to be carefully inserted into the fixing hole. Then, the tip of the fiber is fixed on the surface of the polishing disc by adjustment. However, the adjustment usually requires multiple adjustments to the clamping position, and multiple clamping and fixing points cannot be completed in one operation. Utility Model Content

[0008] 3. According to some embodiments of the present invention, a limiting component is also included;

[0009] The limiting component includes a support block, a first slot, and a moving slot; the bottom of the outer surface of the support block is movably connected to the inner wall of the moving frame, the inner wall of the first slot is movably connected to the outer surface of the connecting column, and the top end of the connecting rod moves within the inner wall of the moving slot.

[0010] A movable frame is fixedly connected to the outer surface of the grinding disc, and a first limiting rod is fixedly connected to the inner wall of the movable frame.

[0011] According to some embodiments of the present invention, the limiting component further includes a second slot and a third limiting groove, wherein the inner wall of the second slot is movably connected to the outer surface of the movable column, and the inner wall of the third limiting groove is sleeved with a first limiting rod.

[0012] According to some embodiments of the present invention, the bottom of the support block is connected to the first limiting rod via a third limiting groove, which allows the support block to move up and down while restricting the movement of the support block.

[0032] like Figures 1-6 As shown, this utility model is a polishing disc adjustment mechanism for an optical fiber polishing machine, comprising:

[0033] The support assembly includes a grinding body 11, a support body 12, a grinding disc 13, and a limiting frame 14. The grinding body 11 is located at the lower end of the support body 12, the grinding disc 13 is located at the top of the support body 12, and four limiting frames 14 are provided, which are evenly distributed on the outer surface of the grinding disc 13.

[0034] The first clamping assembly includes a first clamping plate 21, a first connecting frame 22, a second clamping plate 23, a connecting post 24, a connecting rod 25, and a first limiting groove 26. The first clamping plate 21 and the second clamping plate 23 are symmetrically arranged. The two ends of the first connecting frame 22 are fixedly connected to the two sides of the first clamping plate 21. The top and bottom surfaces of the connecting post 24 are fixedly connected to the upper surface of the second clamping plate 23. The connecting rod 25 is sleeved inside the first limiting groove 26 and is movably connected to the inner wall of the first limiting groove 26. The bottom surfaces of the first clamping plate 21 and the second clamping plate 23 are both located inside the limiting frame 14.

[0035] The second clamping assembly includes a third clamping plate 31, a second connecting frame 32, a fourth clamping plate 33, and a moving column 34. The third clamping plate 31 and the fourth clamping plate 33 are symmetrically arranged and their surfaces are fitted together. The two ends of the second connecting frame 32 are fixedly connected to the two sides of the third clamping plate 31. The bottom of the moving column 34 is fixedly connected to the outer surface of the second connecting frame 32. The third clamping plate 31 and the fourth clamping plate 33 are disposed on one side of the first clamping plate 21 and the second clamping plate 23.

[0036] The second clamping assembly also includes a fixing block 35, a second limiting groove 36, and a second limiting rod 37; the fixing block 35 is fixedly connected to one side of the fourth clamping plate 33, the second limiting groove 36 is opened at the upper part of the fixing block 35, and the two ends of the second limiting rod 37 are disposed on the inner side of the second connecting frame 32 and are fixedly connected to the second connecting frame 32.

[0037] The tail of the fixing block 35 is fixedly connected to the outer surface of the fourth clamping plate 33, and the interior of the second limiting groove 36 is movably connected to the outer surface of the second limiting rod 37.

[0038] The fixing block 35 is located at the lower end of the moving column 34 and inside the second connecting frame 32;

[0039] The connecting column 24 is located at the upper end of the first connecting frame 22 and is movably connected to the outer surface of the first connecting frame 22 via the connecting rod 25;

[0040] The top of the connecting post 24 is triangular, and the top of the moving post 34 is also provided with two inclined surfaces, which fit into the connecting posts 24 on both sides respectively. When the moving post 34 is pulled inward by hand, the inclined surfaces will push the connecting post 24 backward. The first clamping plate 21 in the first clamping assembly will not move. The reverse force of pulling the moving post 34 will push the second clamping plate 23 to clamp the bare optical fiber in the middle of the clamping plate. The fourth clamping plate 33 in the second clamping assembly will not move. When the moving post 34 is pulled, the third clamping plate 31 clamps the bare optical fiber. In this process, it is not necessary to adjust the clamping of the optical fiber at each position many times, which saves more time and effort.

[0041] Working principle: Before the polishing machine is used, the optical fiber is first fixed on the outer surface of the polishing disc 13. At the beginning, the clamping plates are in a relaxed state. Several bare optical fibers are manually placed into the gaps between the clamping plates. Then, when the moving column 34 is pulled, the connecting column 24 will be pushed backward due to the existence of the inclined surface. The first clamping plate 21 in the first clamping assembly will not move. The reverse force of pulling the moving column 34 pushes the second clamping plate 23 to clamp the bare optical fiber in the middle of the clamping plate. The fourth clamping plate 33 in the second clamping assembly will not move. When the moving column 34 is pulled, the third clamping plate 31 clamps the bare optical fiber. In this process, it is not necessary to adjust the clamping of the optical fiber at each position many times, which saves more time and effort.

[0042] like Figure 2 and Figure 6 As shown, this embodiment, based on the above embodiment, also includes a limiting component;

[0043] The limiting component includes a support block 41, a first slot 42, and a moving slot 43; the bottom of the outer surface of the support block 41 is in contact with the inner wall of the moving frame 15, the inner wall of the first slot 42 is in contact with the outer surface of the connecting column 24, and the top of the connecting rod 25 moves on the inner wall of the moving slot 43.

[0044] A movable frame 15 is fixedly connected to the outer surface of the grinding disc 13, and a first limiting rod 16 is fixedly connected to the inner wall of the movable frame 15.

[0045] The limiting assembly also includes a second slot 44 and a third limiting groove 45. The inner wall of the second slot 44 is movably connected to the outer surface of the moving column 34, and the inner wall of the third limiting groove 45 is sleeved with the first limiting rod 16.

[0046] The bottom of the support block 41 is connected to the first limiting rod 16 through the third limiting groove 45, which allows the support block 41 to move up and down, and also restricts the movement of the support block 41.

[0047] In the support block 41, except for the moving groove 43 and the third limiting groove 45, the rest are all through-cut into the support block 41. The two sides of the first groove 42 are connected to the column 24, which moves inside but does not detach from the support block 41. The two sides of the second groove 44 are connected to the outer surface of the moving column 34, so that the moving column 34 can move back and forth inside without detaching from the support block 41. Thus, the various structures are indirectly connected into one. The support block 41 can be lifted up from the moving column 34 part, and the whole can be moved upward and detached from the limiting frame 14. In addition, the space of the third limiting groove 45 is sufficient for the first limiting rod 16 to move back and forth. When the first limiting rod 16 cannot move, the whole clamping and adjusting structure cannot move, but the space for movement is sufficient to drive the whole upward and the clamping plate part to detach from the limiting frame 14, thereby adjusting the tightness of the clamping plate.

[0048] Working principle: When it is necessary to remove or install a bare optical fiber that has been polished, lift the support block 41 upwards from the second connecting frame 32 by hand to move the whole upwards away from the limiting frame 14. In addition, the space of the third limiting groove 45 is sufficient for the first limiting rod 16 to move back and forth. When the first limiting rod 16 cannot move, the whole clamping and adjusting structure cannot move. When the whole is installed in the limiting frame 14, hold the moving columns 34 on both sides to make the whole clamping plate fully inserted into the limiting frame 14 after it is in a clamped state, so that the bottom of the optical fiber contacts the polishing turntable.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
