7. A method for using a bearing press-fitting device, applied to a bearing press-fitting device as claimed in any one of claims 1 to 6, characterized in that: The method of use includes the following steps: Step 1: Move the device to the designated installation position through the moving wheel mechanism; Step 2: Open the lifting block mechanism to adjust the deflection plate mechanism to a specified height, and open the deflection plate mechanism to adjust the deflection positioning rod mechanism to a specified height; Step 3: At this time, the pressing and pulling mechanism is turned on, so that the cardboard pressing mechanism can push the bearing to the desired installation position. Under the action of the cardboard pressing mechanism and the deflection positioning rod mechanism, the cardboard pressing mechanism can be at an adaptive angle. When it is at the adaptive angle, the deflection positioning rod mechanism is turned on to lock the angle. Step 4: Open the cardboard pressing mechanism to expand it, and further open the pressing and pulling mechanism to drive the cardboard pressing mechanism to press the bearing. At the same time, the cardboard pressing mechanism can cool the bearing to achieve cold installation of the bearing.
