A tooth plate automatic milling method, characterized in that: The specific steps include: S1: placing the tooth plate to be milled at the middle position of the top wall of the first flat plate (5), and rotating the handle (21) to drive the threaded rod (23) to rotate, so that the threaded rod (23) can move horizontally during the rotation process under the action of the first mounting nut (26), thereby pushing the abutment plate (25) to move toward one side of the tooth plate, until the two ends of the tooth plate can be tightly engaged and fixed by the two sets of abutment plates (25); S2: When performing step S1, the infrared distance measuring sensor (22) is activated by the PLC controller (9), so that the infrared distance measuring sensor (22) automatically measures the horizontal distance dimension between the infrared distance measuring sensor (22) and the abutting plate (25) and performs real-time monitoring by the PLC controller (9), so that the staff can grasp the specific position of the tooth plate fixing, and can conveniently and accurately control it when it is necessary to fix it to the center point of the first plate (5); S3: after steps S1-S2, the plurality of cylinders (8) are synchronously started to extend and drive the second plate (7) and the first plate (5) to move upward synchronously, thereby driving the tooth plate to move synchronously, and the power tool holder (36) is started to drive the milling tool (35) to rotate, thereby performing milling processing on the tooth plate; S4: When performing step S3, the first forward and reverse motor (19) is started according to the use needs to drive the screw body (18) to rotate, thereby driving the screw nut (16) to move horizontally, and under the action of the screw nut (16), the hanging plate (31), the third plate (33), the milling tool (35) and the power tool holder (36) can be driven to move synchronously, and the second forward and reverse motor (29) is started to drive the first plate (5) and the tooth plate to rotate synchronously, so that different parts of the tooth plate can be milled; S5: When performing steps S3-S4, the electromagnet (34) is started and energized so that it can generate magnetic force, and metal debris is automatically magnetically attracted during the milling process. After the milling process is completed, the first forward and reverse motor (19) is started to drive the lead screw body (18) to rotate, thereby driving the lead screw nut (16) and the electromagnet (34) to move horizontally, so that the two groups of electromagnets (34) are moved to the upper position of the collection frame (2) in turn, and the power supply of the electromagnet (34) at the corresponding position is disconnected to make it lose its magnetism, so that the metal debris magnetically attracted on the surface automatically falls into the inner cavity of the collection frame (2) at the corresponding position for collection; S6: After step S5, the collection frame (2) is moved upward and separated from the support frame (3), and then the metal debris in the inner cavity of the collection frame (2) is dumped out and put back into the collection frame (2) and the clamping rod (4) is re-engaged with the clamping hole (13) to facilitate the use of the next batch; S7: When performing step S4, the first plate (5) can drive the multiple sets of supporting legs (12) and the abutment wheels (28) to rotate synchronously during the rotation process, so that the abutment wheels (28) can rotate on the top wall of the second plate (7), and the stability of the first plate (5) can be further increased with the help of the multiple sets of supporting legs (12) and the abutment wheels (28); S8: screwing the plurality of second bolts (37) to separate them from the threaded holes (39), and then moving the third mounting frame (24) upward to drive the connecting plate (38) to separate from the second plate (7), so as to facilitate disassembly and replacement or disassembly and assembly of the third mounting frame (24) and the first plate (5); S9: twisting the hanging plate (31) to separate it from the second mounting nut (30), and then moving the third plate (33) downward to separate it from the hanging plate (31), so as to facilitate disassembly and replacement or disassembly and assembly of the third plate (33), the electromagnet (34), the milling tool (35) and the power tool holder (36); S10: By connecting the lifting device of the prior art to the lifting ring (15), and then moving the lifting ring (15) upward, the lifting frame (17) and the clamping plate (1) can be driven to move synchronously, thereby separating the lifting frame (17) from the supporting vertical plate (6), and separating the clamping plate (1) from the positioning hole (14), so as to facilitate the disassembly and replacement or disassembly and assembly of the lifting frame (17) and the first forward and reverse motor (19), the screw body (18) and the screw nut (16).
