When the carburetor workpieces to be processed are stacked in the magazine feeding turntable device 2, they are continuously fed and discharged, so that the workpieces to be processed are orderly output and placed, and subsequent riveting processing operations are performed. The workpieces to be processed are transported under the transmission of the feeding and conveying component 3, thereby improving the stability and accuracy of the processing. The transported workpieces to be processed sequentially enter the one-way valve riveting mechanism 4 to rivet the one-way valve on the workpiece, and after the one-way valve riveting processing is completed, the needle valve seat is riveted, and after the needle valve seat riveting is completed, the workpieces to be processed are transported to the one-way valve riveting mechanism 4 to rivet the one-way valve on the workpiece. In the subsequent riveting processing of the oil inlet pipe and the oil return pipe, in each riveting processing, the positioning riveting processing of the parts that need to be riveted on the workpiece is realized after transportation, and the various riveting processing devices are tightly coordinated to achieve precise transfer, coordination and riveting processing during the riveting process. Among them, the set magazine feeding turntable device 2 realizes stable batch transportation of the workpieces to be processed, and the fork linear device 8 realizes stable transportation and riveting support for the workpieces to be riveted. Therefore, the entire device realizes stable riveting processing of multiple parts in the workpiece that needs to be riveted.
