Abstract
The invention relates to a method for machining a bearing ring by fixing the bearing ring to a grinding machine through an auxiliary clamp. The method comprises the steps that firstly, the auxiliary clamp is placed on an electromagnetic suction disk of the vertical grinding machine, the electromagnetic suction disk is not electrified, and a base of the auxiliary clamp is attracted to the electromagnetic suction disk through residual magnetism; secondly, the auxiliary clamp is knocked through a tool, so that a locating base of the auxiliary clamp is aligned with the grinding machine; thirdly, the bearing ring needing machining is arranged on the locating base of the auxiliary clamp in a sleeving mode, so that the end face of the bearing ring is located on a supporting ring face of a support; and finally a pressing plate is used for pressing the bearing ring on the auxiliary clamp, and the grinding machine is started to machine the bearing ring. By means of the method for machining the bearing ring, the problem that the roundness and the concentricity of a bearing outer ring are poor is effectively solved, the bearing ring is fixed to the electromagnetic suction disk of the grinding machine through the auxiliary clamp, the phenomenon that the end face of the bearing ring deforms due to magnetic attraction and discontinuous supporting can be avoided, and therefore the grinding precision of the bearing ring is guaranteed.
Description
Technical field
The present invention relates to grinding bearing rings technical field, be specifically related to a kind ofly bearing ring is fixed on by auxiliary clamp the method that grinding machine carries out processing.
Background technology
Vertical grinder belongs to a kind of high-precision grinder, the mill machining bearing lasso of domestic, external production at present all adopts vertical grinder, vertical grinder is before processing, first bearing ring is placed on magnechuck, then be energized to magnechuck, the method utilizing the magnetic force of multiple magnetic pole directly to suck ring face is fixed, and position (such as by the method for manually knocking bearing ring centering, during mill machining bearing outer ring external diameter, need knock bearing outer ring, the inner surface of centering bearing outer ring is located).Although this localization method is simple, quick, higher and hold yielding bearing ring for some required precisions, above-mentioned localization method can not meet the technological requirement of lasso circularity and concentricity.Main cause is: on the one hand, because the discontinuity of the multiple magnetic poles adsorbing bearing ring causes lasso to be out of shape; On the other hand, manually knock the human error of centering and knock the lasso distortion caused.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, there is provided a kind of and bearing ring is fixed on by auxiliary clamp the method that grinding machine carries out processing, the machining accuracy of bearing ring can be improved, guarantee that the bearing ring product processed has good circularity and concentricity.
The present invention is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind ofly bearing ring is fixed on by auxiliary clamp the method that grinding machine carries out processing, auxiliary clamp comprises step-like circular cylinder, step-like circular cylinder be pedestal bottom, the top of pedestal is supporting base, the top of supporting base is positioning seat, concrete processing method is: be first placed on the magnechuck of vertical grinder by auxiliary clamp, magnechuck is in no power state, the pedestal of auxiliary clamp is adsorbed on magnechuck by residual magnetism, then instrument is used to knock auxiliary clamp, the positioning seat of auxiliary clamp is made to align grinding machine, then will the bearing ring of processing be needed to be set on the positioning seat of auxiliary clamp, the end face of bearing ring is made to be placed on the supporting anchor ring of supporting base, finally with pressing plate, bearing ring is pressed on auxiliary clamp, open grinding machine to process bearing ring, after completion of processing, the auxiliary clamp of bearing ring from grinding machine is taken down.
Bearing ring is fixed on by auxiliary clamp the further improvements in methods that grinding machine carries out processing as the present invention is a kind of: described pedestal is along the circumferential direction evenly provided with multiple axial installing hole, this installing hole is spare mounting hole, when needs, auxiliary clamp is fixed on magnechuck through installing hole by bolt.
Bearing ring is fixed on by auxiliary clamp the further improvements in methods that grinding machine carries out processing as the present invention is a kind of: the external diameter 1 ~ 2mm less of bearing ring external diameter of described supporting base.This is to prevent abrasive wheel end face and supporting base from interfering.
Bearing ring is fixed on by auxiliary clamp the further improvements in methods that grinding machine carries out processing as the present invention is a kind of: the upper surface of described positioning seat, for guiding the conical surface, is convenient to bearing ring to be set on the positioning seat of auxiliary clamp.
beneficial effect
Grinding bearing rings method of the present invention efficiently solves circularity and the overproof problem of concentricity of bearing outer ring, bearing ring is fixed on the magnechuck of grinding machine by auxiliary clamp, the distortion that end surface of bearing ring causes due to magnetic-adsorption and discontinuous supporting can be avoided, thus ensure that the mill machining accuracy of bearing ring, and when positioning, directly do not knock bearing ring, but the position of bearing ring is adjusted by knocking auxiliary clamp, avoid and knock distortion, for the mill machining accuracy improving bearing outer ring provides guarantee.
