Technical Field
[0001] The utility model relates to the technical field of core adjustment clamps, in particular to a polarization-maintaining optical fiber core adjustment clamp. Background Art
[0002] Optical fiber is mainly made of high-purity glass or plastic, and its core technology lies in the principle of total reflection of light. With the advancement of material science, the materials used to make optical fiber have been optimized to improve the transmission efficiency and stability of light. At the same time, the manufacturing technology of optical fiber is also constantly evolving, from the initial basic preparation process to the current precision drawing, coating and cutting technology.
[0003] At present, in the existing technology, the existing adjustment method is to manually rotate the optical fiber, use an industrial camera to shoot the end face of the optical fiber, and then display the image taken by the camera on the display screen. The operator can see the position of the optical fiber cat's eye by watching the display screen. However, this adjustment method has a relatively low success rate when connecting optical fibers, and also requires the operator to have high professional quality. In view of this, we propose a polarization-maintaining optical fiber core adjustment fixture. Utility Model Content

[0006] A center column, the surface of the center column is fixedly connected to the end surface of the rotating handle, the surface of the center column is rotatably connected to the inner wall of the mounting handle, the end surface of the center column is fixedly connected to the end surface of the placement table, and a V-shaped placement groove is provided on the surface of the placement table.
[0007] Preferably, the mounting handle comprises handle 1, and handle 1 is fixedly connected to handle 2 via bolts, and handle 1 and the inner wall of handle 2 are rotatably connected to the surface of the center column.
[0008] Preferably, the pressing plate comprises a plate body, an inner wall of the plate body is fixedly connected with a magnet block, and an upper surface of the plate body is fixedly connected with a handle.

[0012] Beneficial Effects
[0013] The utility model provides a polarization-maintaining optical fiber core adjustment fixture, which has the following beneficial effects:
[0014] (1) The polarization-maintaining optical fiber core-adjusting fixture has a rotating handle. When the angle of the optical fiber fixed on the placement table needs to be adjusted, it is only necessary to rotate the rotating handle so that the rotating handle drives the placement table to rotate, so that the optical fiber rotates along with the placement table. Compared with manual rotation of the optical fiber, the rotation of the fixture body can more stably control the force and angle of the rotating optical fiber, thereby improving the production quality.
[0015] (2) The polarization-maintaining optical fiber core-adjusting fixture places the optical fiber on a placement table so that the surface of the optical fiber is inserted into the interior of the V-shaped placement groove, and then places a pressure plate on the upper surface of the placement table. Because the placement table is made of ferromagnetic material, the magnet block is firmly adsorbed on the upper surface of the placement table, so that the magnet block drives the plate body to squeeze the surface of the optical fiber, thereby fixing the optical fiber on the upper surface of the placement table, which is convenient for subsequent adjustment of the optical fiber angle.
