The traverse unit drives the clamping unit to move above the clamping assembly. The upward movement of the indexing plate drives the clamping assembly upward. The distance adjustment unit operates to control the opening and closing of the first clamping plate and the second clamping plate once, and the clamping assembly clamps the upper frame. The clamping unit releases the clamping of the upper frame, the indexing plate moves downward to drive the clamping assembly downward, the second clamping plate elastically clamps the upper frame under the action of the elastic assembly, the pressing unit of the upper frame press-fitting module moves downward and press-fits the upper frame and the iron core monomer under the guidance of the profiling unit, and the first assembly is obtained after press-fitting; The clamping unit of the lower frame press-fitting module clamps the lower frames in batches from the lower frame receiving assembly, and the transverse movement unit drives the clamping unit to move to the top of the lower frame positioning seat. The clamping unit releases the clamping of the lower frame, and the lower frame falls into the lower frame positioning seat for positioning; The clamping assembly clamps the first assembly, the indexing plate drives the clamping assembly upward, the first assembly separates from the core positioning seat, and the indexing plate drives the clamping assembly to rotate above the lower frame positioning seat; The indexing plate drives the clamping assembly downward, and the second clamping plate elastically clamps the first assembly under the action of the elastic assembly. The pressing unit of the lower frame press-fitting module presses the first assembly and the lower frame to obtain the second assembly. The indexing plate drives the clamping assembly upward, and the indexing plate drives the clamping assembly to rotate to the discharge position.
