Description
Technical Field
The utility model belongs to the assembly quality of bearing product, concretely relates to electric riveting device that large-scale cylindrical roller bearing kept ware.
Background
Cylindrical roller bearing structures are typically separate pieces, either inner or outer. The retainers are generally of a two-body structure, and the rolling bodies, the inner ring (or the outer ring) and the retainers are riveted into an assembly during assembly, wherein the riveting mode generally comprises cold riveting and electric riveting. The large cylindrical roller bearing is generally riveted electrically, but because the large bearing is heavy in weight, the large cylindrical roller bearing is difficult to move when the large cylindrical roller bearing is riveted electrically manually, sometimes several people are needed to cooperate to rotate the assembly, time and labor are wasted, the phenomena of deflection, different sizes of rivet heads, crushing damage and electric corrosion on the surface of the retainer often occur, and the whole retainer is repaired or scrapped due to the defect of riveting.
Disclosure of Invention
The utility model provides an electric riveting device of large-scale cylindrical roller bearing retainer to solve large-scale cylindrical roller bearing electric riveting quality problems and production efficiency problem, improve economic benefits.
In order to achieve the above purpose, the following technical scheme is adopted: the electric riveting device of the bearing retainer is divided into two parts, namely a first part: the bottom of the combined tire is a circular lower tire, an arc-shaped channel is formed in the upper surface of the bottom tire along the circumference, the rolling bodies, the steel balls, are assembled in the arc-shaped channel of the lower tire, the upper portions of the rolling bodies, the steel balls, are assembled in the arc-shaped channel formed in the lower surface of the circular upper tire (3) along the circumference, and the upper tire (3) and the rolling bodies, the steel balls, can freely rotate along the arc-shaped channel in the circumferential direction of the lower tire; a second part: the electric riveting clamping fixture (4) with the groove in the circumference is fixedly installed on the upper surface of the upper fixture (3), the depth of the groove of the clamping fixture (4) is not less than the size of the part of the retainer pillar which is higher than the retainer check ring A (9) by the sixth, and the inner diameter of the electric riveting clamping fixture (4) is not more than the outer diameter of the bearing inner ring (8).
The utility model has the advantages that: the assembled rolling element assembly is placed on an electric riveting mould, can rotate freely in the circumferential direction, is riveted by an electric riveting machine, reduces the operating strength of an electric riveter, and has stable electric riveting quality and improved production efficiency.
Drawings
Fig. 1 is a schematic structural view of the electric riveting device.
Description of the drawings: the device comprises a lower tire 1, a rolling body-steel ball 2, an upper tire 3, an electric riveting mold 4, a retainer retaining ring B5, a retainer pillar 6, a cylindrical roller 7, a bearing inner ring 8 and a retainer retaining ring A9.
Detailed Description
The present invention will be described in detail with reference to the following drawings and specific embodiments:
the electric riveting device of the retainer is divided into two parts, wherein the first part is a combined clamping fixture which can rotate along the circumferential direction: the upper tire (3) and the rolling bodies-the steel balls are assembled in the arc-shaped channel of the circumference of the lower tire, and can freely rotate in the circumferential direction on the lower tire; the second part is that an electric riveting clamping fixture (4) with a groove on the circumference is fixedly arranged on the upper surface of the upper mould (3), and the electric riveting clamping fixture (4) can freely rotate along the circumferential direction along with the combined clamping fixture; the groove depth of the electric riveting clamping fixture (4) is determined according to the dimension that one surface of the rolling element assembly with the threaded retainer pillar is higher than a retainer check ring A (9) with a threaded hole, the groove depth of the electric riveting clamping fixture (4) is not smaller than the dimension that the retainer pillar is higher than the retainer check ring A (9), and the part of the retainer pillar higher than the retainer check ring A (9) can be in the groove, so that the rolling element assembly is not interfered with the electric riveting clamping fixture (4); the inner diameter of the electric riveting clamping fixture (4) is determined according to the outer diameter of the bearing inner ring (8), and the inner diameter of the electric riveting clamping fixture (4) is not larger than the outer diameter of the bearing inner ring (8).
The rolling element assembly comprises a retainer retaining ring B with a cylindrical hole, a retainer pillar, a cylindrical roller (7) with a pillar hole, a bearing inner ring (8) and a retainer retaining ring A (9).
And placing the mounted rolling element assembly on an electric riveting mould (4) and riveting on an electric riveting machine.
