Clamping and vibrating device for plastic-dipped bearing retainer

Abstract

The invention discloses a clamping and vibrating device for a plastic-dipped bearing retainer. The clamping and vibrating device for the plastic-dipped bearing retainer comprises a radial moving mechanism, a clamping mechanism, vibrators and an axial lifting mechanism, wherein the radial moving mechanism comprises a driving part and at least three moving parts, and the driving part drives the moving parts to move along the radial direction of the retainer; the clamping mechanism comprises at least three clamping parts, and the clamping parts are connected with the moving parts and used for clamping the retainer; the vibrators are arranged on the clamping parts or the moving parts so as to vibrate the retainer; and the axial lifting mechanism is arranged above the radial moving mechanism and connected with the radial moving mechanism so as to drive the retainer to move in the vertical direction. According to the invention, redundant outer-side molding powder on the retainer can be removed, so that a plastic layer of the retainer is uniform, flat and firm.

Description

technical field [0001] The invention relates to the technical field of bearing retainers, in particular to a clamping vibration device for a plastic dipped bearing retainer. Background technique [0002] The cage (that is, the bearing cage, also known as the bearing cage) refers to the bearing parts that partially wrap all or part of the rolling elements and move with them, to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearing Inside. When the rolling bearing is working, especially when the load is complex and rotates at high speed, the cage has to bear a lot of centrifugal force, shock and vibration, there is a large sliding friction between the cage and the rolling elements, and a lot of heat is generated. The result of the combined action of force and heat can lead to failure of the cage, and in severe cases, it will cause burns and fracture of the cage. Therefore, the cage material is required to have good thermal conducti...

Problems solved by technology

[0003] However, during the dipping process of the bearing cage, when the cage is taken out of the plastic powder, the plastic powder on the surface close to the metal surface tends to melt and shape, and the closer to the outside of the plastic powder, because the temperature of the cage itself Weakened, resulting in the outer plastic powder cannot be completely melted into the plastic layer, at this time it is necessary to remove the outer plastic powder as soon as possible, so that the thickness of the plastic layer after molding is uniform, so as to avoid affecting the quality of the plastic layer, currently limited by the clamping tooling, the vibration effect of the cage Poor, the excess plastic powder cannot be removed in time, which increases the difficulty of subsequent processing, and the vibration structure is unreliable, which can easily lead to loose clamping, and the vibration process needs to consume more energy, which needs to be solved urgently
