The invention discloses a friction plate steel backing full-automatic drilling machine. The friction plate steel backing full-automatic drilling machine comprises a machine frame, an automatic discharging device, a trough, a human-computer interface controller, a system supporting frame, a first tray assembly, a second tray assembly, an automatic feeding device, a multi-station rotation disc device, product pressing blocks, drilling power devices, an angle adjusting device and a sliding table Z shaft. The friction plate steel backing full-automatic drilling machine is a horizontal multi-station drilling machine, a multi-station rotation disc system is adopted so that feeding, drilling machining and discharging can be conducted at the same time, the structural design is more reasonable, small-size friction plate steel backings and small-included-angle friction plate steel backings can be machined, in addition, a friction plate steel backing of which the two holes are parallel is machined, the two holes are machined at the same time, mutual noninterference is achieved, the machining cycle is shortened, and the production efficiency is greatly improved from 25s/pcs to smaller than orequal to 10s/pcs; and through the scheme, the product automatic feeding function is achieved, the labor intensity of workers is greatly relieved, and the equipment automation degree is improved.
