Automatic correcting device for assembly angle of rotating shaft

The invention provides an automatic correcting device for the assembly angle of a rotating shaft. The technical defect that in the prior art, the assembly angle of a rotating shaft of a stepping motoris large in error, and therefore the follow-up automatic screw fixing working procedure cannot be normally carried out is overcome. According to the adopted technical scheme, the automatic correctingdevice comprises a lifting mechanism, a telescopic correcting assembly with a correcting column and a rotary driving assembly. The correcting column is used as a terminal executing element and executes the operation of rotating the to-be-corrected rotating shaft to be in place, and drive comprises two aspects, namely rotary drive and lifting drive. Through lifting drive, the correcting column isclose to or away from the to-be-corrected rotating shaft in the vertical direction. When correcting is needed, lifting drive drives the correcting column to be close to the to-be-corrected rotating shaft, and after correcting i
