The present invention provides a device for ejecting completely assembled universal joints outwardly. The present invention relates to a device for ejecting universal joints, including first and second yokes having a pair of fork arms with a ball shaft formed on the fork arms, respectively, and a spider for connecting rotationally the first and second yokes and having an end part formed in a cross. The device comprises: a first yoke support unit (40) for supporting the first yoke (10); a second yoke support unit (60) for supporting the second yoke (20); and an ejecting pin (62) operated by a pneumatic cylinder (60) and seated on the first and second yoke support units for pushing by being in contact with one side of the completely assembled universal joint of a spider bearing. At this time, the first and second yokes are formed perpendicular to each other to be seated on the yoke support units. The first yoke support unit includes a pair of arc-shaped support units (42) formed concavely to support the arc-shaped bottom end of the first yoke, and a pair of support steps (44) formed inside the arc-shaped support units, respectively to be in contact with the inner surface of the fork arm of the first yoke. The second yoke support unit comprises a first support unit (64) for supporting the bottom surface of the fork arm of the second yoke, and a second support unit (62) for supporting the bottom surface of a shaft of the second yoke. |
