Description

Technical Field

[0001] The present application relates to the technical field of optical fiber laser cutting, and in particular to an optical fiber cutting clamping fixture. Background Art

[0002] In the fiber optic communications industry, the end faces of optical fibers typically require grinding and polishing, a relatively cumbersome and costly process. This led to the emergence of laser fiber cutting, which meets optical requirements while improving efficiency and reducing costs. However, laser fiber cutting is sensitive to focal length. If the fiber is placed inconsistently each time, or there is a pitch angle, this can easily lead to unstable angles and poor length consistency in the fiber end face after cutting. Therefore, the fiber needs to be mounted on a fixture before cutting, and then the fixture is placed on the laser cutting machine. Therefore, the operability and stability of the cutting fixture are very important. Current fiber clamping fixtures make it difficult to firmly clamp and secure the fiber, which can easily cause fiber misalignment and ultimately lead to unstable laser cutting. Utility Model Content

[0033] For details, please refer to Figures 1 to 4 The embodiment of the present application provides an optical fiber cutting and clamping fixture 10 for clamping an optical fiber product 20, wherein the optical fiber product 20 includes a main body shell 201 and an optical fiber ferrule 202, wherein the optical fiber cutting and clamping fixture 10 includes an optical fiber positioning base plate 1, a flip-locking pressure cover 2 and a buffer pressing mechanism 3; the middle portion of the optical fiber positioning base plate 1 is provided with a contoured groove 11 for placing the main body shell 201, the first end of the optical fiber positioning base plate 1 is provided with a card slot structure 12 for clamping the optical fiber ferrule 202, the card slot structure 12 It is arranged on a straight line with the contoured groove 11; the flip-fitting cover 2 is rotatably connected to the first end of the optical fiber limiting placement base plate 1, and the flip-fitting cover 2 can be fastened and locked with the optical fiber limiting placement base plate 1; the buffer clamping mechanism 3 is arranged on the flip-fitting cover 2 and corresponds to the slot structure 12, and the buffer clamping mechanism 3 includes a pressing block 31, a mounting block 32 and an elastic member 33, the pressing block 31 is arranged on the mounting block 32, and the mounting block 32 is connected to the flip-fitting cover 2 through the elastic member 33.

[0034] When the flip-fitting cover 2 rotates relative to the optical fiber limiting placement base plate 1, the pressing block 31 abuts and presses the optical fiber ferrule 202 located in the slot structure 12, and the mounting block 32 buffers the rotational stress by squeezing or stretching the elastic member 33 to keep the position of the pressing block 31 relative to the optical fiber ferrule 202 unchanged, thereby preventing the optical fiber ferrule 202 from being dislocated and offset due to the rotational stress. In this way, the flip-fitting cover 2 can apply greater pressure to the optical fiber ferrule 202 to clamp the optical fiber ferrule 202, thereby facilitating laser cutting of the optical fiber on the optical fiber ferrule 202.

[0035] The elastic member 33 is preferably a compression spring 123, a coil spring, or an elastic column. The pressing block 31 is made of an elastic buffer material. When the optical fiber ferrule 202 is squeezed, the pressing block 31 can buffer stress and deform, thereby achieving tight compression with the optical fiber ferrule 202. The optical fiber ferrule 202 is preferably a fiber insertion carrier such as a jump, MT, or MiniMT.

[0036] See also Figure 4 The flip-fitting cover 2 is provided with a groove 21, and the buffer pressing mechanism 3 is arranged in the groove 21. In this way, the flip-fitting cover 2 can be kept flush with the surface of one side of the optical fiber limiting placement base plate 1 to prevent interference with the optical fiber product 20.

[0037] See also Figure 4 The flip-fitting cover 2 is rotatably connected to the first end of the optical fiber positioning base plate 1 via a rotating shaft 22. The pressure block 31, the mounting block 32, and the elastic member 33 are sequentially arranged, with the pressure block 31 being arranged adjacent to the rotating shaft 22. At least two elastic members 33 are provided in the groove 21, and the elastic members 33 maintain the mounting block 32 in contact with the inner wall of the groove 21 through elastic force. When the flip-fitting cover 2 rotates relative to the optical fiber positioning base plate 1, the flip-fitting cover 2 drives the pressure block 31 to rotate. The pressure block 31 is fixed to the mounting block 32. The mounting block 32 buffers the rotational stress by squeezing or stretching the elastic member 33 to keep the position of the pressure block 31 relative to the optical fiber ferrule 202 unchanged, thereby preventing the optical fiber ferrule 202 from being displaced or offset due to the rotational stress.

[0038] It is understandable that the groove 21 is also provided with at least two guide columns, and through holes are provided on both sides of the mounting block 32. The guide columns pass through the through holes, and the elastic member 33 is sleeved on the guide columns to enable the mounting block 32 to slide along the guide columns to avoid position displacement.

[0039] See also Figure 6 A sliding stop hole is provided at the bottom of the groove 21. A stop post 321 extends from the bottom of the mounting block 32. The stop post 321 slides along the elastic member 33 within the sliding stop hole to prevent positional displacement. If the elastic member 33 becomes stuck, the stop post 321 can be manually unlocked by moving it.

That is, the area surrounded by the top surface of the support plate 13, the end limiting protrusion 121 and the front spring placement block 122 is used to clamp the optical fiber ferrule 202, and the end limiting protrusion 121 and the front spring placement block 122 clamp the two side edges of the optical fiber ferrule 202.

[0041] See also Figure 2 The optical fiber product 20 includes an optical fiber cable 203, see Figure 3 The front spring placement block 122 and the rear spring placement block 124 are provided with cable clamping grooves 125 at positions corresponding to the contoured grooves 11. In this way, the optical fiber cable 203 is accommodated in the cable clamping grooves 125, so that the upper surfaces of the front spring placement block 122 and the rear spring placement block 124 are flush with the upper surface of the optical fiber limit placement base plate 1.

[0042] See also Figure 3 、 Figure 6 、 Figure 7 The slot structure 12 includes an end plate 126, on which the end stop protrusion 121 is disposed. The end plate 126 is detachably connected to the first side of the support plate 13. The detachable connection of the end plate 126 allows for the removal and replacement of only the end plate 126 if the end stop protrusion 121 is broken or deformed due to long-term use, without having to replace the entire fiber stop base plate 1.

Preferably, the distance between the first placement bevel 127 and the top surface of the support plate 13 is greater than or equal to the thickness of the optical fiber ferrule 202, and the distance between the second placement bevel 128 and the top surface of the support plate 13 is greater than or equal to the thickness of the optical fiber ferrule 202.

[0044] See also Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The fiber positioning base plate 1 is provided with lower hook blocks 14 on both sides, and upper hook clamping blocks 23 are extended on both sides of the flip-locking pressure cover 2.

The lower hook block 14 is C-shaped, and the upper hook block 24 is in an inverted C-shape. The upper hook block 24 can be flipped and elastically reset, so that the upper hook block 24 can be pressed and rotated to lock or unlock with the lower hook block 14.
