The rotor bearing clamping mechanism 6 clamps the heated rotor bearings one by one, and the pushing mechanism 5 pushes and presses them into the end of the rotor. Finally, the rotor clamping and transporting mechanism 8 is used to clamp the unloaded material.

[0033] Specifically, the rotor bearing assembly device of the vacuum servo motor includes a workbench 1 and a vibration plate mounting table 2, a vibration plate 3 arranged on the vibration plate mounting table 2 and carrying a plurality of rotor bearings to be installed, a transmission mechanism 4 arranged on the workbench 1 and transmitting the rotor bearings loaded on the vibration plate 3, a rotor support mechanism 7 arranged on the workbench 1 and placing the rotor to be assembled, a pushing mechanism 5 arranged on the workbench 1, a rotor bearing clamping mechanism 6 arranged on the pushing mechanism 5 and clamping the rotor bearings transmitted on the transmission mechanism 4 one by one, and a rotor clamping and transporting mechanism 8 arranged on the workbench 1 and pressing and transporting the rotor on the rotor support mechanism 7. When the rotor bearing is pressed into the end of the rotor, the rotor clamping and transporting mechanism 8 is used to press the rotor on the rotor support mechanism 7 to prevent the rotor from moving backward.

[0034] In this embodiment, the transmission mechanism 4 includes a transmission belt mechanism 41, a material-digging and pushing mechanism, and a lifting mechanism arranged on the workbench 1, and a transmission belt motor 42 arranged on the transmission belt mechanism 41.

When the rotor bearing is loaded, the flip driving cylinder 63 is used to drive the bearing clamping sleeve 67 vertically downward, and with the cooperation of the lifting mechanism, the rotor bearing in the heater 49 is pushed into the bearing clamping sleeve 67. The bearing clamping sleeve 67 is arranged in the horizontal direction by the flip driving cylinder 63, and is pushed by the push-in cylinder, so that the heated rotor bearing enters the end of the rotor to achieve press-in installation.
