Abstract
The utility model relates to a supplementary anchor clamps for processing of bearing ring grinding machine, including the annular cylinder of step form, the annular cylinder of step form is by supreme base, bearing and the positioning seat of being respectively down, and the bottom of base has the adsorption plane, and evenly is provided with a plurality of axial installation holes along the circumferencial direction on the base, and the up end of bearing be continuous smooth annular bearing surface, and the up end of positioning seat is for guiding the conical surface. The utility model discloses a bearing inner race's circularity and the overproof problem of concentricity have been solved effectively to supplementary anchor clamps, bearing ring fixes on the electromagnet of grinding machine through supplementary anchor clamps, can avoid the bearing ring terminal surface because magnetic force adsorbs and discontinuous supporting and the deformation that arouses, thereby bearing ring's mill machining precision has been guaranteed, and when fixing a position, directly do not strike bearing ring, but adjust bearing ring's position through strikeing supplementary anchor clamps, the deformation has been avoided strikeing, mill machining precision for improving bearing inner race provides the assurance.
Description
Technical field
The utility model relates to grinding bearing rings technical field, is specifically related to a kind of auxiliary clamp for bearing-ring grinder 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.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and provides a kind of auxiliary clamp for bearing-ring grinder processing, can improve the machining accuracy of bearing ring, guarantee that the bearing ring product processed has good circularity and concentricity.
The utility model is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: a kind of auxiliary clamp for bearing-ring grinder processing, auxiliary clamp comprises step-like circular cylinder, step-like circular cylinder is respectively pedestal, supporting base and positioning seat from the bottom to top, the bottom of pedestal has the adsorption plane that can be adsorbed on electromagnetic chuck of grinder, and pedestal is along the circumferential direction evenly provided with multiple axial installing hole, the upper surface of described supporting base is the annular bearing surface of continuous formation, and the upper surface of positioning seat is for guiding the conical surface.
Further improvement as a kind of auxiliary clamp for bearing-ring grinder processing of the utility model: 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.
beneficial effect
Auxiliary clamp of the present utility model 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.

Detailed description of the invention
As shown in the figure: a kind of auxiliary clamp for bearing-ring grinder processing, comprise step-like circular cylinder, step-like circular cylinder is respectively pedestal 1 from the bottom to top, supporting base 2 and positioning seat 3, the bottom of pedestal 1 has the adsorption plane that can be adsorbed on electromagnetic chuck of grinder 4, and pedestal 1 is along the circumferential direction evenly provided with multiple axial installing hole 6, the upper surface of described supporting base 2 is the annular bearing surface of continuous formation, the upper surface of positioning seat 3 is for guiding the conical surface, bearing ring 5 is convenient to be set on the positioning seat 3 of auxiliary clamp, external diameter 1 ~ the 2mm less of bearing ring external diameter of described supporting base 2.This is to prevent abrasive wheel end face and supporting base from interfering.The upper surface of positioning seat 3 is guide the conical surface and have rational cooperation between positioning seat 3 with bearing ring 5, has both ensured being installed conveniently of bearing ring 5, in turn ensure that bearing ring 5 is in self-centering state after putting into fixture.Concrete processing method is: be first placed on by auxiliary clamp on the magnechuck 4 of vertical grinder, magnechuck 4 is in no power state, the pedestal 1 of auxiliary clamp is adsorbed on magnechuck 4 by residual magnetism, then instrument is used to knock auxiliary clamp, the positioning seat 3 of auxiliary clamp is made to align grinding machine, then will the bearing ring 5 of processing be needed to be set in (as shown in Figure 2) on the positioning seat 3 of auxiliary clamp, the end face of bearing ring 5 is made to be placed on the supporting anchor ring of supporting base 2, finally with pressing plate, bearing ring 5 is pressed on auxiliary clamp, open grinding machine to process bearing ring 5, after completion of processing, the auxiliary clamp of bearing ring 5 from grinding machine is taken down.
Auxiliary clamp of the present utility model 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.
More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection domain of the present utility model.
