Description

Technical Field

[0001] The utility model relates to the technical field of hub bearing production, in particular to a hub bearing outer ring press-fitting die. Background Art

[0002] Wheel hub bearings are components used in automobile axles to bear weight and provide precise guidance for the rotation of the wheel hub. They bear both axial and radial loads and are an important component of automobile load-bearing and rotation. Wheel hub bearing units are developed on the basis of standard angular contact ball bearings and tapered roller bearings. They integrate two sets of bearings into one unit and have the advantages of good assembly performance, no need for clearance adjustment, light weight, compact structure, large load capacity, grease can be pre-loaded for sealed bearings, no need for external wheel hub seals, and no need for maintenance. They have been widely used in cars and are also gradually expanding their application in trucks.

[0003] Ordinary press-fitting equipment only has a device to fix the outer ring of the bearing, but does not position the wheel hub. If positioning is not performed, the relative position between the wheel hub and the outer ring of the bearing may deviate, resulting in inaccurate installation. In addition, there is no buffering device during the press-fitting process, and the impact force during the press-fitting process cannot be effectively controlled, which may lead to reduced press-fitting accuracy and insufficient fit between the wheel hub and the bearing. At the same time, excessive impact force may cause damage to the press-fitting equipment, such as the press-fitting machine, mold, etc., increasing maintenance costs. Utility Model Content

When the moving block 523 moves, it drives the third spring 528 to stretch. Place the hub on the top of the placement disc 522, release the arc-shaped limiting plate 524, the third spring 528 rebounds, drives the moving block 523 to slide inwards inside the placement disc 522. At the same time, the moving block 523 drives the arc-shaped limiting plate 524 and the second rubber pad 525 to move, so that the second rubber pad 525 contacts the hub. The four second rubber pads 525 position the hub, so that the inside of the hub is directly below the bearing outer ring.

When the first guide rod 515 slides, it drives the second spring 518 to contract. When the installation of the outer ring of the bearing is completed, start the motor 414, and the motor 414 drives the threaded rod 416 to rotate in the reverse direction. The threaded rod 416 drives the moving sleeve 417 to move upward, and at the same time drives the T-shaped movable rod 418, the fixed block 4111 and the first rubber pad 4112 to move inward through the push rod 419, releasing the fixation of the outer ring of the bearing. After releasing, the stamping column 411 contracts, and at the same time the first spring 514 and the second spring 518 rebound without external force, driving the support platform 512 to return to its original position, and then the hub can be taken out.
