Problems solved by technology

For the processing of thin-walled bearing rings with large diameters, due to the thin wall thickness of the rings, different degrees of warping deformation of the end face will occur after the heat treatment process. Due to its poor rigidity, it will produce a certain axial deformation. In

Example Embodiment

[0016] The specific embodiments of the present invention will be described in further detail below.

[0017] A method for grinding the end face of a thin-walled bearing ring, comprising the following steps:

[0018] 1) Select a flat reference steel plate, coat one end face of the thin-walled bearing ring with adhesive one by one, and place the end face on the flat reference steel plate to make it bond with the flat reference steel plate in a natural state ;

[0019] 2) Place a period of time so that the thin-walled bearing ring and the plane reference steel plate are firmly bonded. In the above two steps, the thin-walled bearing ring is not affected by any external force in the natural state, and no new deformation will occur. ;

[0020] 3) Adsorb the plane reference steel plate on the magnetic disk of the surface grinder to grind the upper end face of the thin-walled bearing ring; at this time, the adsorption force of the magnetic disk acts on the plane reference steel plat...

Abstract

The invention relates to a method for grinding end faces of thin-walled bearing rings. The method is characterized by comprising the following steps of selecting a planar reference steel plate, adhering one end face of each thin-walled bearing ring to the planar reference steel plate under a natural state by using an adhesive, adsorbing the planar reference steel plate to a magnetic disk of a surface grinding machine after the end face is firmly adhered, and grinding one end face of each thin-walled bearing ring; directly adsorbing each thin-walled bearing ring to the magnetic disk of the surface grinding machine after adhesion is removed, and grinding the other end face of each thin-walled bearing ring. The technological process is reasonable, the influence on end face grinding caused by warping deformation of the end faces of the thin-walled bearing rings is eliminated, the flatness of the end faces of the rings is guaranteed, the machining accuracy of bearings is improved, and the qualification rate of bearing products is improved.

Description

technical field [0001] The invention relates to a bearing processing method, in particular to a method for grinding the end face of a thin-walled bearing ring. Background technique [0002] The grinding process of the end face of the bearing ring is usually carried out after the heat treatment process is completed. The end face grinding of the bearing ring is carried out on a surface grinder. The bearing ring is placed flat on the magnetic disk. Under the action of the magnetic force, the bearing ring is absorbed and Secured to the disk so that the ferrule does not come off during the face grinding process. For the processing of thin-walled bearing rings with large diameters, due to the thin wall thickness of the rings, different degrees of warping deformation of the end face will occur after the heat treatment process. Due to its poor rigidity, it will produce a certain axial deformation. In this state, when the end face is ground, when the disk suction is eliminated, the ...
