The invention belongs to the technical field of a motor
impeller, in particular to a production method of a mortised and riveted
impeller. The production method comprises the steps: step 1, material preparation: preparing a lower
impeller tray, blades and an upper impeller tray as required,
cutting lower tray mortises in the lower impeller tray,
cutting upper tray mortises in the upper impeller tray, and
processing tenons on the two ends of each blade; step 2,
assembly: mounting a plurality of blades on the lower impeller tray and the upper impeller tray one by one, inserting the blade tenons on one side of the lower impeller tray into the lower tray mortises or tongue-and-grooves in the corresponding positions of the lower impeller tray, inserting the blade tenons on one side of the upper impeller tray into the upper tray mortises or tongue-and-grooves in the corresponding positions of the upper impeller tray, and thus obtaining an impeller packaging body; step 3,
rivet-pressing:
rivet-pressing the blade tenons of the impeller packaging body obtained in the step 2 and the
insertion positions of the upper tray mortises or tongue-and-grooves and the lower tray mortises or tongue-and-grooves by using
rivet-pressing equipment, riveting the blade tenons with the upper tray mortises or tongue-and-grooves and the lower tray mortises or tongue-and-grooves, and thus obtaining an impeller
assembly. The production method has the advantages of less procedure, high production efficiency and stable impeller structure.
