[0034] The four driven gears 34 are meshed with four racks 35 respectively, and the top ends of the four racks 35 are fixedly connected with inner support plates 36 .

[0035] The overall shape of the four inner support plates 36 is annular.

[0036] The specific implementation process of this embodiment is as follows: the motor 33 is used to drive the driving gear 331 to rotate, thereby rotating the rotating gear ring 31, and then rotating the four driven gears 34. When the driven gear 34 rotates, it will drive the rack 35 meshing with it to slide on the fixed ring 32, and the four racks 35 approach or move away from each other, so that the inner support plate 36 supports and fixes the inner ring of the flange. In the process of the racks 35 approaching or moving away from each other, the diameter of the circular ring formed by the inner support plate 36 is constantly changing, so as to fix flanges of different models.

[0037] Embodiment 2:

The punching assembly 6 is fixedly connected to the top plate 2, and the cleaning assembly includes a fixed plate 4 fixedly connected to the top surface of the processing machine tool 1.

[0039] At least four material dropping grooves 41 are formed through the top of the fixing plate 4 , and the at least four material dropping grooves 41 are evenly distributed on the top of the fixing plate 4 .

The blanking groove 41 is a rounded square to adapt to the punching operation of flanges of different sizes. After the punching is completed, the waste chips will enter the blanking groove 41. The staff rotates the rotating handle 511 to rotate the screw rod 51, so that the threaded slider 52 moves on the screw rod 51, and then the rotating plate 54 rotates.
