Referring to fig. 1 to 5, a precision alignment mechanism for optical fibers includes a mounting plate 1, and a coupling portion 2 is fixedly connected to a middle position of a top of the mounting plate 1. The coupling part 2 is made by processing transparent epoxy resin, conical guide holes 3 are processed on two opposite side surfaces of the coupling part 2, and the conical shapes of the guide holes 3 are arranged from the outer side to the inner side in a decreasing mode. The guide holes 3 on the two sides are communicated at the tip cone part of the guide hole 3 through the coupling hole 4. The inner wall of the coupling hole 4 is coated with a black or other dark contrast coating 15 with a semi-cylindrical side wall, so that the insertion condition of the optical fiber in the coupling hole 4 can be observed conveniently, and the mutual collision of the two optical fiber ends is avoided. The coupling hole 4 is also communicated with a matching fluid adding hole 14, the matching fluid adding hole 14 is communicated with a matching fluid adding system, and the matching fluid is added into the coupling hole 4, so that the optical signal loss is reduced, and the coupling quality is improved.

On the mounting plate 1, elongated moving grooves are formed on both sides of the coupling part 2 at positions aligned with the guide holes 3. The optical fiber clamping parts 5 at two sides of the coupling part 2 are fixedly connected with an air cylinder 8 fixed at the bottom of the mounting plate 1 through a connecting rod passing through the moving groove. The pushing direction of the cylinder 8 is toward the coupling part 2. A reversing switch 9 and a click switch 10 are also mounted on the top of the mounting plate 1. The reversing switch 9 is used for controlling the driving direction of the air cylinder 8, inserting the optical fiber into the coupling hole 4 for coupling at the same time, and pushing the optical fiber out after the test is finished; the inching switch 10 is convenient for adjusting the moving speed of the cylinder 8, the long-time pressing quick moving speed and the inching small-distance moving speed, so that the adjustment can be more accurate.

The fiber clamping portion 5 is a combination of cylindrical and conical shapes. Where the conical shape is matched to the taper of the guiding hole 3, where the matching conical surfaces are used to ensure the alignment accuracy of the optical fibres. An optical fiber passage 6 penetrating the cylindrical and conical portions is opened at a position on the center axis of the optical fiber holding portion 5, and the optical fiber is accommodated therein. A pair of elastic holders 7 are provided inside the optical fiber passage. The elastic clamping device 7 is composed of two springs 11 and a back clamping plate 12. One end of the spring 11 is fixed on the inner wall of the optical fiber channel 6, and the other end is fixed on the top of the clamping plate 12. A V-groove for clamping the optical fiber is formed at the bottom of the clamping plate 12. The use of resilient clamping means here ensures that the fibre is always centred in the fibre channel 6 when it is clamped. To facilitate the installation of the optical fibers, a pull ring 13 is attached to the outside of a clamping plate 12 at the top by a round rod.

The use principle is as follows: the optical fiber is inserted between the two clamping plates 12 by pulling the pull ring 13, so that part of the optical fiber passes through the conical end of the optical fiber clamping part 5, and the air cylinder 8 drives the optical fiber clamping part 5 to be coupled to the coupling part 2 by pressing the inching switch 10. Wherein the guide hole 3 is used for guiding, when the optical fiber is inserted into the coupling hole 4, the control cylinder 8 is inching by observing the moving speed condition of the optical fiber through the contrast coating 15, and after the optical fiber reaches the position, the matching fluid is injected from the matching fluid adding hole 14 to improve the coupling quality.
