Problems solved by technology

[0004] The object of the present invention is to provide an anti-deformation device for sealing ring assembly and its use method, to solve the problem mentioned in the prior art that when the sealing ring is stamped and assembled, there is no preliminary positioning of the sealing ring on the bearing, which is easy During stamping, the bearing is deformed due to the offset of the sealing ring. At the same time, after assembling one side of the bearing, the bearing needs to be removed, and then the other side of the bearing should be assembled. In the process of loading and unloading, continuous stamping assembly cannot be carried out. Low efficiency, technical problems affecting use

Abstract

The anti-deformation device comprises a base, a rack is fixedly installed on the base, a gear ring is rotatably installed on the upper surface of the base, no less than six assembling seats are fixedly installed on the upper surface of the gear ring, bearings are placed on the assembling seats, sealing rings are placed at the upper ends of the bearings, and the sealing rings are fixedly installed on the rack. A hydraulic cylinder is fixedly mounted at the top end in the rack, a pressing plate is fixedly connected to the extending end of the hydraulic cylinder, and sliding blocks are fixedly connected to the two ends of the pressing plate. In the using process, a bearing needing to be assembled with a sealing ring is placed on the assembling base, a pressing plate moves downwards to extrude a piston pipe, so that a second piston plate moves downwards, then negative pressure is generated in a piston cavity above a second piston, air between an inner ring body and an outer ring body on the bearing is absorbed through a negative pressure pipe, and the sealing ring is arranged on the bearing. Therefore, the sealing ring can be adsorbed on the bearing, and the phenomenon of deformation caused by deflection of the sealing ring in the assembling process is avoided.

Description

technical field [0001] The invention relates to the related technical field of sealing ring assembly, in particular to a deformation preventing device for sealing ring assembly and a method of using the same. Background technique [0002] A bearing is a precise mechanical element that converts the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings generally include outer rings, inner rings, rolling elements, cages, sealing rings and Lubricant, among which the sealing ring plays an important role in the performance and life of the bearing. During the assembly process of the bearing, the sealing ring needs to be press-fitted into the corresponding groove. [0003] Most of the existing sealing rings are assembled manually, and the efficiency is low, and some are assembled by corresponding devices, such as the Chinese utility model patent with the publication number: CN212318560U, "including the b...
