Description

Technical Field

[0001] The utility model relates to the technical field of rotor production, in particular to a double-station automatic press-fitting machine. Background Art

[0002] The motor rotor is composed of a rotating shaft, rotor punching sheets and N pairs of magnetic steel with opposite polarities. For the press-fitting of the loose sheets, the inner hole has an interference fit, and the relative interference fit is large. In addition, the outer circle of the punching sheet is not reprocessed after press-fitting. In order to improve the press-fitting efficiency and press-fitting quality, the press-fitting machine adopts a frame structure, and the positioning template is fixed to the bed. Existing press-fitting machines mostly use manual or semi-automatic production for assembly. With the popularization of intelligent and automated modern industrial production, the production efficiency is relatively reduced, and the traditional press-fitting machine cannot load and press-fit at the same time. For this reason, a double-station automatic press-fitting machine is proposed. Utility Model Content

[0009] Technical effects and advantages of the utility model:
