[0031] The clamping block 404 is arranged on one side of the fixing assembly close to the connecting plate 2. There are three clamping blocks 404, and the three clamping blocks 404 can move towards or away from each other.

[0032] The fixing assembly includes a rotating block 401, the outer wall of which is rotatably connected to the inner wall of the mounting hole via a bearing, the outer wall of the rotating block 401 is fixedly connected to a hinge rod 402, the outer wall of the hinge rod 402 is hinged to a hinge frame 403, the hinge frame 403 is fixedly connected to a clamping block 404 at one end close to the connecting plate 2, the side of the rotating block 401 away from the connecting plate 2 is rotatably connected to a threaded pile 405 via a bearing, the side of the rotating block 401 away from the connecting plate 2 is also fixedly connected to a plug rod 406, the outer wall of the threaded pile 405 is threadedly connected to a slider 407, the inner wall of the slider 407 is slidably connected to the outer wall of the plug rod 406, the outer wall of the slider 407 is fixedly connected to a support block 408, the number of the support blocks 408 and the hinge frames 403 are both three, and the positions of the three support blocks 408 and the three hinge frames 403 are correspondingly arranged, and the thickness of the right side of the support block 408 is less than the thickness of the left side of the support block 408.

[0033] The outer walls of the two rotating blocks 401 on one side close to the connecting plate 2 are fixedly connected with a slide 13, and the inner wall of the slide 13 is inserted with a connecting rod 12. The outer walls of both ends of the connecting rod 12 are slidably connected with the inner walls of the two slides 13 respectively. The outer wall of the first fixed pile 1 is also provided with a threaded telescopic rod 14, one end of the threaded telescopic rod 14 is rotatably connected to the right side of the outer wall of the first fixed pile 1 through a bearing, and the other end of the threaded telescopic rod 14 is rotatably connected to the outer wall of the second fixed rod 3 through a bearing.

[0034] The tilting mechanism 15 includes a spring 501, the upper end of the spring 501 is slidably connected to the lower side of the outer wall of the first fixed pile 1, the lower end of the spring 501 is fixedly connected to the base plate 502, the upper side of the outer wall of the base plate 502 is fixedly connected to the hydraulic push rod 503, the upper end of the hydraulic push rod 503 is hinged to a hinge block 504, the upper side of the outer wall of the hinge block 504 is slidably connected to the lower side of the outer wall of the first fixed pile 1, there are two springs 501, hydraulic push rod 503 and hinge block 504, the upper sides of the spring 501 and hinge block 504 on the right side are slidably connected to the lower side of the second fixed rod 3.

[0035] When in use, the two sides of the optical fiber preform are respectively placed in the middle of the clamping block 404, and after the optical fiber preform is fixed, the first motor 5 is started to drive the clamping mechanism 4 to rotate, so that the clamping mechanism 4 drives the optical fiber preform to rotate, and the second motor 7 is started at the same time, so that the second motor 7 drives the threaded rod 8 to rotate. Since the mass of the lower part of the sliding pile 9 is greater than the sum of the masses of the upper part of the sliding pile 9, the blowtorch 10, and the infrared rangefinder 11, the gravity of the lower part of the sliding pile 9 is greater than the friction between the outer wall of the threaded rod 8 and the inner wall of the sliding pile 9 when the threaded rod 8 rotates, the threaded rod 8 is connected to the sliding pile 9 by a thread. When the sliding pile 9 moves, the sliding pile 9, the blowtorch 10, and the infrared rangefinder 11 slowly move from one end of the lower side of the optical fiber preform to the other end of the optical fiber preform. At the same time, the infrared rangefinder 11 can measure the distance from the infrared rangefinder 11 to the surface of the optical fiber preform. When the distance from the surface of the optical fiber preform to the surface of the infrared rangefinder 11 exceeds a preset value, the blowtorch 10 is started to heat the optical fiber preform to melt a part of the optical fiber preform, and the melted part is evenly distributed along with the rotation. Then, the blowtorch 10 is turned off to re-solidify the surface of the optical fiber preform, so as to achieve the purpose of surface straightness detection and correction.

[0036] While the clamping mechanism 4 fixes the optical fiber preform, the slider 407 can be translated on the threaded pile 405 by rotating the threaded pile 405, thereby changing the distance between the support block 408 and the rotating block 401. When the support block 408 is close to the rotating block 401, the support block 408 pushes the hinge frame 403 to make the clamping blocks 404 close to each other. When the support block 408 is away from the rotating block 401, the clamping blocks 404 are away from each other, so that the clamping force of the clamping block 404 can be conveniently adjusted, and the thickness of the clamping can be adjusted, so as to adjust the clamping force of the optical fiber preform and the clamping position of the optical fiber preform, so as to prevent the rotation vibration caused by the uneven thickness and inconsistent clamping height at both ends of the optical fiber preform, and the height of the two ends can be made consistent by adjusting the clamping position of the optical fiber preform, so as to reduce the vibration during rotation and increase the accuracy of direct reading measurement of the surface of the optical fiber preform.

[0037] At the same time, since the rotating blocks 401 on both sides are connected by the slide cylinder 13 and the connecting rod 12, the rotating blocks 401 on both sides can ensure the same rotation speed and rotation angle when rotating, so as to prevent the breakage and uneven surface cladding caused by the inconsistent rotation speeds at both ends when heating the surface of the optical fiber preform, and the distance between the first fixed pile 1 and the second fixed rod 3 can be adjusted by the threaded telescopic rod 14, so that the first fixed pile 1 and the second fixed rod 3 can be moved to both sides when heating the thicker part of the optical fiber preform, so that the heated part of the optical fiber preform can be thinned;

[0038] When the optical fiber preform is heated, the hydraulic push rod 503 on one side is started to tilt the first fixing pile 1 and the second fixing rod 3. By repeatedly raising and lowering the hydraulic push rods 503 on both sides, when the blowtorch 10 heats the optical fiber preform, the flame heats both sides of the heating part synchronously, thereby preventing the optical fiber preform from being broken due to local high temperature.

[0039] In addition, during the reciprocating tilting process of the first fixed pile 1 and the second fixed rod 3, the melted portion on the surface of the optical fiber preform rod is uniformly flow-coated on the left side of the main body surface, thereby preventing the melted glass solution from being thrown outwards due to centrifugal force during rotation, and preventing the melted glass solution from gathering in the middle due to the surface tension of the liquid to cause uneven thickness.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
