s2: when the driving bevel gear (48) rotates, the driving bevel gear (48) is meshed with the driven bevel gear (49) and the driven bevel gear (49) is mounted on the second transmission screw rod (410) through a spline, so that the driven bevel gear (49) and the second transmission screw rod (410) can also rotate along with the driving bevel gear (48) so as to move the second traction sliding block (411), the second support connecting rod (412) and the second arc-shaped abutting block (413), and the second arc-shaped abutting block (413) is also tightly attached to the inner circumferential surface of the annular blank (3) to be processed;
s3: the annular blank (3) to be processed is abutted and fixed on the rotating table (21) through the first arc-shaped abutting block (47) and the second arc-shaped abutting block (413), and at the moment, the hydraulic cylinder (51) drives the gear shaper cutter (6) to move downwards, so that the gear shaper cutter (6) performs gear shaping processing on the annular blank (3) to be processed;
s4: after the gear slotting machining, the hydraulic cylinder (51) drives the pinion cutter (6) to move upwards, the rotating motor (2) drives the rotating platform (21) and the annular blank (3) to be machined to rotate for 28.8 degrees anticlockwise under the guiding action of the guide ring (7) and the balls (71), and the hydraulic cylinder (51) drives the pinion cutter (6) to move downwards, so that the pinion cutter (6) performs the gear slotting machining on the annular blank (3) to be machined again, and the steps are sequentially circulated until the annular blank (3) to be machined is machined into a gear;
s5: in the process of tooth punching of the annular blank (3) to be machined, the micro pump (53) is started, so that cooling liquid in the cooling liquid tank (52) is pumped into the cooling hose (8), and the cooling liquid is sprayed through the cooling spray head (81) to further cool the annular blank (3) to be machined and the pinion cutter (6).
