the angle fine adjustment mechanism comprises a rotating part, wherein the rotating part is connected with the clamping part to drive the clamping part to rotate along a central axis parallel to the axial direction of the retainer so as to align the process hole.

8. The apparatus as claimed in claim 7, wherein the rotating member comprises a second motor, a base of the second motor is connected to the moving member, an output shaft of the second motor is connected to a driving gear, the driving gear is engaged with a driven gear, the driven gear is coaxially connected to a connecting rod, and the connecting rod detachably connects the holding member and the moving member.

9. The clamping vibration device for the plastic-impregnated bearing holder as claimed in claim 8, wherein the rotor housing is provided with a reinforcing shell, the reinforcing shell is connected to the rotor, the reinforcing shell is provided with a through hole, the connecting rod is arranged through the through hole, and the inner wall of the through hole is provided with a reinforcing sleeve abutting against the connecting rod.

10. The clamping vibration device for the plastic-impregnated bearing retainer as claimed in claim 1, wherein the clamping member is a clamping rod, and the shape of the end surface of the clamping rod corresponds to the shape of the fabrication hole; the radial size of one end of the clamping rod is larger than that of the process hole and is set as a first end; the radial size of the other end of the clamping rod is less than or equal to that of the process hole, and the other end is set as a second end; so that the clamping rod can be in interference fit with the process hole.
