Abstract

The application discloses a wheel hub oil seal assembling tool and an assembling method. The tool comprises a workbench provided with a through hole, a press-fitting mechanism and a press-fitting power piece. The press-fitting mechanism comprises an inner oil seal press head and an outer oil seal press head located at the through hole. The inner oil seal press head and the outer oil seal press head are oppositely arranged. The inner oil seal press head and the outer oil seal press head are connected with the press-fitting power piece. Under the driving of the press-fitting power piece, the inner oil seal press head and the outer oil seal press head can move up and down. The outer oil seal press head can pass through the through hole during the up and down movement. The inner oil seal press head comprises an inner oil seal press head guide part, an inner oil seal flange press-fitting part and an inner oil seal inner side skeleton press-fitting part. The inner oil seal inner side skeleton press-fitting part is a downward protruding protrusion. The inner oil seal flange press-fitting part is located outside the inner oil seal inner side skeleton press-fitting part. The application effectively avoids the leakage of lubricating grease during the use of the wheel hub, improves the reliability of the wheel hub, ensures the reliability of the vehicle and improves the safety factor of the vehicle.
