[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] like Figure 1 , Figure 2 As shown in the figure, this utility model embodiment provides an optical fiber bevel polishing device, including a polishing machine body 1 and a polishing disc 2. The mechanism includes a polishing machine body, a polishing disc, a support platform, a mounting column, a rotating sleeve, a guide rail assembly, an optical fiber fixing assembly, etc., constituting a complete polishing system.

[0034] The upper surface of the grinding machine body 1 forms a bearing platform 101, and the grinding disc 2 is arranged on the bearing platform 101. The upper side of the grinding disc 2 is provided with a mounting column 11 arranged on the top of the guide rail assembly 3. The mounting column 11 is arranged on the side of the grinding machine body 1 in the vertical direction. A rotating sleeve 5 is arranged on the top of the mounting column 11 (as shown in Figure 3 The rotating sleeve 5 is connected and fixed by a self-locking screw 51. The top of the guide rail assembly 3 is connected with the rotating sleeve 5, and the guide rail assembly 3 rotates 360° in the horizontal direction through the rotating sleeve 5. The top of the rotating sleeve 5 is provided with a deflection slot 501, and one end of the hinged support 301 is hinged in the deflection slot 501. The hinged support 301 is rotationally fixed by the pin 502 penetrating the side of the deflection slot 501 (that is, the hinged support 301 can rotate 360° along the pin 502 at this time). The other end of the hinged support 301 is connected with the horizontally fixed fixed support plate 302. The guide rail assembly 3 is fixed on the front end surface of the fixed support plate 302. At this time, the back surface of the fixed support plate 302 is provided with a waist-shaped connecting hole, which is fixedly connected with the guide rail assembly 3 through the waist-shaped connecting hole. This connection mode can adjust the relative height of the guide rail assembly 3 in the vertical direction. At the same time, the upper part of the guide rail assembly 3 is connected with the fixed support plate 302 in the vertical direction through the first adjusting screw 303, and the local displacement of the guide rail assembly 3 in the vertical direction is adjusted through the first adjusting screw 303. In this way, the position of the guide rail assembly 3 relative to the fixed support plate 302 can be finely adjusted without disassembling the guide rail assembly 3.

[0035] As shown in Figure 4 The bottom of the guide rail assembly 3 is connected and fixed with the optical fiber fixing assembly 4. The optical fiber fixing assembly 4 moves linearly in the vertical direction through the guide rail assembly 3.

[0036] The included angle between the optical fiber fixing assembly 4 and the table surface of the bearing platform 101 is 0°-70°. In this way, the bare optical fiber 8 carried can be in contact with the grinding disc 2 at a certain inclination angle, which is convenient for grinding the end part.

[0037] As shown in Figure 5 , Figure 6As shown, the optical fiber fixing assembly 4 comprises an optical fiber fixing seat 41, a micro linear guide rail 42 and an optical fiber pressing block 43. The optical fiber fixing seat 41 has an overall L-shaped structure, and the optical fiber pressing block 43 is slidably connected to the optical fiber fixing seat 41 through the micro linear guide rail 42 along the extension direction of the optical fiber fixing seat 41. At this time, a plurality of parallel strip-shaped V-shaped grooves 411 are arranged on the front end surface of the optical fiber fixing seat 41, and the V-shaped grooves 411 are used to load and place the bare optical fiber 8. Meanwhile, a plurality of parallel pressing strips 431 are arranged on the lower end surface of the optical fiber pressing block 43 along the extension direction of the V-shaped grooves 411, and the pressing strips 431 are used to press the bare optical fiber 8 loaded in the V-shaped grooves 411, so as to realize the clamping of the bare optical fiber 8 by the front end of the optical fiber pressing block 43 and the front end of the optical fiber fixing seat 41. That is, when the bare optical fiber 8 is polished, the bare optical fiber 8 between adjacent two groups will not be intertwined, and the bare optical fiber 8 itself will not rotate.

[0038] In order to meet the requirements that the optical fiber pressing block 43 is connected through the second adjusting screw 432 on the top thereof, and the optical fiber pressing block 43 is locally displaced along the micro linear guide rail 42, that is, the function of fine adjustment is realized. The locking of the optical fiber fixing seat 41 and the optical fiber pressing block 43 is realized by tightening the second adjusting screw 432, and the separation of the optical fiber fixing seat 41 and the optical fiber pressing block 43 is realized by loosening the second adjusting screw 432, so as to facilitate the taking of the bare optical fiber 8.

[0039] In specific use, first, the grinding parameters of the grinder are adjusted;

[0040] The optical fiber fixing assembly 4 is rotated to the appropriate position of the grinding disc 2, and the first adjusting screw 303 is locked.

[0041] The optical fiber is loaded into the V-shaped groove 411 of the optical fiber fixing assembly 4 and is pressed tightly, so as to prevent the optical fiber from rotating during polishing.

[0042] The grinding disc 2 is started to rotate for polishing, the adjusting screw is slowly adjusted to the left to make the optical fiber slowly descend, and the optical fiber is polished to form an inclined surface.

[0043] After the optical fiber is polished, the adjusting screw is turned to the right, so that the optical fiber is completely separated from the grinding disc.

[0044] Finally, the second adjusting screw 432 is loosened, and the optical fiber is taken out.

[0045] The above shows and describes the basic principle, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
