Description
Technical Field
[0001] The utility model relates to a riveting device for an automobile wheel hub bearing. Background Art
[0002] During the riveting process of the wheel hub bearing, the center line of the rivet head is at a certain angle to the center line of the rotating shaft, and the rivet head rotates and swings around the center of the rotating shaft to achieve swing riveting. When the product is lifted up and contacts the rivet head, the rivet head applies an outward force to the inner side of the top of the inner flange, causing the top of the inner flange to begin to deform outward. In traditional riveting machines, the small ring of the bearing is not restricted during the product lifting riveting process, and the rivet head mounting shaft can rotate freely. During the riveting process, the product swings left and right, and there is relative friction between the rivet head surface and the inner flange riveting plane, which results in an uneven riveting plane after riveting, an uneven rivet point shape, a large amount of expansion of the small ring after riveting, and a slight deformation of the small ring groove.
