[0051] The turning system as a core machining component is provided with the first turning assembly and the second turning assembly at the first working position and the second working position respectively, and the two are arranged back to back, so that the raw material disc in each clamping assembly can be turned. The first clamping assembly and the second clamping assembly of the clamping system correspond to the working sides of the first turning assembly and the second turning assembly respectively, and clamping the inner ring or the outer ring of the raw material disc provides stable clamping and fixing for the turning and punching processes, ensures that the raw material disc does not displace during machining, and guarantees machining accuracy. After the second turning is completed, the punching system performs drilling operation on the raw material disc fixed on the second clamping assembly at the second working position by means of the drill bit 21 connected to the second turning assembly, and the drilling action is realized by using the power transmission of the turning assembly, so that the turning and punching processes can be completed cooperatively.

[0052] The working process of the flange plate turning and drilling integrated machine provided by the application is as follows: first, according to the processing requirements of the raw material plate, the raw material plate is placed at the first clamping assembly of the first working position, the inner ring or the outer ring of the raw material plate is clamped by the first clamping assembly, and the fixing of the raw material plate at the first working position is completed; then, the turning system is started, the first turning assembly of the first working position starts to work, the raw material plate fixed on the first clamping assembly is turned and processed, and the predetermined turning process of one side of the raw material plate is completed; after the first turning assembly completes the processing, the raw material plate is taken off from the first clamping assembly and transferred to the second clamping assembly of the second working position, the inner ring or the outer ring of the raw material plate is clamped by the second clamping assembly, and the fixing of the raw material plate at the second working position is realized; then, the second turning assembly is started, the second turning assembly turns and processes the raw material plate fixed on the second clamping assembly, and the predetermined turning process of the other side of the raw material plate is completed; finally, after the second turning assembly completes the turning, the drill bit 21 of the drilling system is driven by the second turning assembly to work, the drill bit 21 drills the raw material plate on the second clamping assembly, and the drilling process of the raw material plate is completed.

[0053] When the first clamping assembly clamps the inner side of the raw material plate, the second clamping assembly clamps the outer side of the raw material plate; when the first clamping assembly clamps the outer side of the raw material plate, the second clamping assembly clamps the inner side of the raw material plate.
