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
The present invention relates to a kind of bearing processing method, especially relate to a kind of thin-wall bearing ring face grinding processing method.
Background technology
The grinding of end surface of bearing ring is carried out usually after heat treatment step completes, end surface of bearing ring grinding is carried out on surface grinding machine, on the disk that bearing ring lies in, under the effect of magnetic force, bearing ring is adsorbed and is fixed on disk, lasso is added at cross grinding and can not come off man-hour.For in the thin-wall bearing ferrule processing that diameter is larger, because lasso wall thickness is thinner, end face buckling deformation in various degree can be produced after heat treatment step, when cross grinding, lasso by disk suction adsorption at disk, due to the poor rigidity of itself, certain axial deformation can be produced, in this state grinding end face, when after elimination disk suction, there is resilience in bearing ring, the ring face warpage after being ground still can existence to a certain degree, is difficult to the flatness ensureing end surface of bearing ring.End surface of bearing ring is the height of the benchmark of following process, its precision, directly affects the machining accuracy of bearing, has larger impact to the qualification rate of product.
Summary of the invention
The applicant is for above-mentioned problem, be studied improvement, a kind of thin-wall bearing ring face grinding processing method is provided, eliminate thin-wall bearing ring face buckling deformation to the impact of cross grinding, ensure the flatness of ring face, improve the machining accuracy of bearing, improve the qualification rate of bearing products.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of thin-wall bearing ring face grinding processing method, select one block of datum plane steel plate, by multiple thin-wall bearing ferrule in its natural state, with bonding agent, an end face is bonded on datum plane steel plate, bonding firmly after, datum plane steel plate is adsorbed on the disk of surface grinding machine, an end face of grinding thin-wall bearing ferrule; Remove bonding after, thin-wall bearing ferrule is directly adsorbed on the disk of surface grinding machine, another end face of grinding thin-wall bearing ferrule.
Further:
Concrete steps are as follows:
1) select one block of datum plane steel plate, one by one thin-wall bearing ferrule end face bonding agent smoothened and by this end face horizontal on datum plane steel plate, make it bond together with datum plane steel plate in its natural state;
2) time period of placement makes thin-wall bearing ferrule bonding with datum plane steel plate firmly;
3) datum plane steel plate is adsorbed on the disk of surface grinding machine, the upper surface of grinding thin-wall bearing ferrule;
4) take off datum plane steel plate and immerse in solvent, making thin-wall bearing ferrule remove bonding from datum plane steel plate;
5) thin-wall bearing ring face of grinding is adsorbed on the disk of surface grinding machine, another end face of grinding thin-wall bearing ferrule;
6) be up to the standards into subsequent processing.
Technique effect of the present invention is:
A kind of thin-wall bearing ring face grinding processing method disclosed by the invention, technological process is reasonable, eliminates thin-wall bearing ring face buckling deformation to the impact of cross grinding, ensures the flatness of ring face, improve the machining accuracy of bearing, improve the qualification rate of bearing products.
Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
Thin-wall bearing ring face grinding processing method, comprises the steps:
1) select one block of datum plane steel plate, one by one thin-wall bearing ferrule end face bonding agent smoothened and by this end face horizontal on datum plane steel plate, make it bond together with datum plane steel plate in its natural state;
2) time period of placement makes thin-wall bearing ferrule bonding with datum plane steel plate firmly, and in above-mentioned two steps, thin-wall bearing ferrule in its natural state, not by the impact of any external force, new distortion can not occur;
3) datum plane steel plate is adsorbed on the disk of surface grinding machine, the upper surface of grinding thin-wall bearing ferrule; Now the absorption affinity of disk acts on datum plane steel plate, and can not act on thin-wall bearing ferrule, and the buckling deformation of the thin-wall bearing ferrule upper surface of now grinding is polished, and thin-wall bearing ferrule upper surface flatness now grinding can reach technical requirement.
4) take off datum plane steel plate and immerse in solvent, thin-wall bearing ferrule is made to remove bonding from datum plane steel plate, due in its natural state always, not by the impact of external force, remove bonding after thin-wall bearing ferrule, the end face plane degree after being ground can not produce resilience, still keeps qualified, as the benchmark of the next end face of grinding, still there is original buckling deformation in another unprocessed end face.
5) thin-wall bearing ring face of grinding is adsorbed on the disk of surface grinding machine, another end face of grinding thin-wall bearing ferrule, and will dimensional requirement be ground to.
6) be up to the standards into subsequent processing.
Due in whole grinding process; thin-wall bearing ferrule is not by the impact of external force; the distortion of the thin-wall bearing ferrule that external force causes can not occur and cause new distortion after causing grinding; improve yield rate and the qualification rate of thin-wall bearing ferrule grinding; ensure the flatness of ring face; improve the machining accuracy of bearing, improve the qualification rate of bearing products.
