Optical fiber alignment device

The invention discloses an optical fiber alignment device, which belongs to the field of optical fiber communication, and comprises a first micromotion plate, a second micromotion plate, a base plate,a first optical fiber support, a second optical fiber support and a ceramic V-shaped groove, and after the first micromotion plate, the second micromotion plate and the base plate are connected intoa whole through screws, grooves for installing the first optical fiber support and the second optical fiber support are integrally machined, and the machining difficulty of a single part of the micromotion plate is reduced. The ceramic V-shaped groove is mounted in the first optical fiber support and the second optical fiber support as an integral part, and then a middle connecting part is knockedto be removed, so that the optical fiber alignment precision is improved; the first micro-motion plate and the second micro-motion plate are composed of single-parallel four-rod flexible hinge mechanisms, tension springs are i
