Adjustable electric riveting fixture for extra-large-size bearing retainer

Abstract

The invention relates to an auxiliary locating tool for carrying out electric riveting and welding between an extra-large-size bearing strut and a retainer in the bearing industry, in particular to an adjustable electric riveting fixture for an extra-large-size bearing retainer, which is characterized by comprising a base, wherein the base is connected with a supporting plate (4) for placing a bearing to be welded through an inclined adjusting mechanism, thereby adjusting an angle of inclination of the bearing; the supporting plate (4) is respectively provided with an upper locating support (5), a left locating support (6) and a right locating support, and the three supports are all installed in a clamping slot in the supporting plate (4), thereby moving along the clamping slot to fix bearings of different sizes, wherein the upper locating support (5) is also connected with a lifting mechanism so as to move up and down. By adopting the fixture provided by the invention, the position of the bearing to be welded can be adjusted as required, thereby, an optimal electric riveting working position can be realized, not only burning internal assemblies by electrical sparks is reduced, but also deformation of a single-row tapered roller bearing, caused by the welding of the strut and the retainer, can be reduced.

Description

technical field [0001] The invention relates to an auxiliary positioning tool for electric riveting welding between a super-large bearing pillar and a cage in the bearing industry, in particular to an adjustable electric riveting jig for a super-large bearing cage. Background technique [0002] Electric riveting welding is the most effective way for the domestic bearing industry to weld the super large bearing pillar and cage, but this welding method has not been extended to the welding of tapered roller bearing pillar and cage at present, because this type of bearing With a taper, and the size of the taper is not fixed, and the diameter varies greatly. The welding positions of each specification of this type of bearing are different, so it is difficult to perform electric riveting welding on this type of bearing. At present, the domestic support for this type of bearing is Most of the welding with the cage is arc welding. The deformation of the cage is large and the size is...

[0002] Electric riveting welding is the most effective way for the domestic bearing industry to weld the super large bearing pillar and cage, but this welding method has not been extended to the welding of tapered roller bearing pillar and cage at present, because this type of bearing With a taper, and the size of the taper is not fixed, and the diameter varies greatly. The welding positions of each specification of this type of bearing are different, so it is difficult to perform electric riveting welding on this type of bearing. At present, the domestic support for this type of bearing is Most of the welding with the cage is arc welding. The deformation of the cage is large and the size is unstable, which often causes the side swing of the bearing to be out of tolerance. Because of the arc welding, electric sparks are easy to be generated, and the inner raceway and rollers in the inner components Local burns have seriously affected the product quality of this type of bearing
