Automatic press-fitting equipment for plug of electric heating drying frame and press-fitting method

The invention discloses automatic press-fitting equipment for a plug of an electric heating drying frame. The automatic press-fitting equipment comprises a machine frame, and further comprises two sets of press-fitting units arranged on the machine frame, an amplitude modulation device and a conveyor, and the press-fitting units are oppositely and symmetrically arranged and used for press-fitting the plug on a drying frame; the amplitude modulation device is connected with one set of press-fitting units and controls the distance between the connected set of press-fitting units and the other set of press-fitting units to adapt to the length of the drying frame; and the conveyor is used for conveying the drying frame. Automatic press-fitting operation of the drying frame plug is achieved, the press-fitting efficiency and quality are both guaranteed, adjustment of drying frames of different specifications is achieved through the arranged amplitude adjusting device and the two sets of press-fitting units which ar
