Flexible positioning and pressing bearing device for motor rotor

The invention relates to a flexible positioning and pressing bearing device for a motor rotor, and the device is characterized in that the device comprises a guide frame, a clamping mechanism, a lifting adjustment mechanism, a left sleeve pressing mechanism, a right sleeve pressing mechanism, a left ejection mechanism, and a right ejection mechanism, and the clamping mechanism, the lifting adjustment mechanism, the left sleeve pressing mechanism, and the right sleeve pressing mechanism are all disposed on the guide frame. The left ejection mechanism is arranged on the left casing pressing mechanism, and the right ejection mechanism is arranged on the right casing pressing mechanism. According to the invention, automatic coaxial clamping and positioning and bearing pressing functions can be carried out on various different types of motor rotors with the same shaft diameter; the problem that in the existing motor rotor assembling link, bearing press fitting can be carried out only when a positioning jig needs t
