This utility model discloses an FA fiber array polishing angle adjustment structure, relating to the field of FA fiber array polishing technology. The technical solution includes a fiber polishing machine with a vertical drive assembly on top and an angle drive connecting frame connected to one side of the vertical drive assembly. The beneficial effects of this FA fiber array polishing angle adjustment structure are: through the three-dimensional linkage of the vertical drive assembly, the angle drive connecting frame, and the angle adjustment assembly, a multi-degree-of-freedom adjustment system of "height-horizontal angle-rotation" is constructed. Servo motor two, in conjunction with threaded rod two, can achieve continuous adjustment of the horizontal angle from 3° to 60°. Servo motor three drives the fiber rotation, and combined with the movement of the polishing disc, it can precisely process complex end faces such as conical, wedge-shaped, and spherical shapes, breaking through the limitations of traditional equipment that can only polish in a plane or at a single angle, and meeting the diverse needs of high-speed optical communication, fiber optic sensing, and other fields.
