Automatic optical fiber cutting equipment

The utility model provides automatic optical fiber cutting equipment, and belongs to the technical field of optical fiber cutting. According to the technical scheme, the optical fiber cutting device is characterized by comprising a machine base, a fixing mechanism and a cutting mechanism, a limiting hole is formed in the limiting mechanism, a cutter capable of automatically cutting optical fibers is arranged on the cutting mechanism, and a clamping jaw assembly capable of automatically clamping the optical fibers is arranged on a stretching assembly; after the optical fiber penetrates through the limiting hole, the first X-axis moving module is started, so that the clamping jaw assembly is started, then the first Y-axis moving module is started, the stretching assembly is moved to the end of the optical fiber, the clamping jaw assembly grabs the optical fiber, then the stretching assembly pulls the optical fiber to a certain length, and then the shearing mechanism is started to shear the optical fiber.
