Abstract

The invention relates to a grinding method of a thin-wall outer ring with a hole. A step-by-step grinding method is adopted and comprises the following steps of: roughly grinding an excircle, regrinding a raceway and flanges, and finally carrying out fine grinding on the excircle, wherein the step of roughly grinding the excircle comprises: carrying out cut-in grinding by use of a circular grinding machine, grinding the outer diameters of a hole and an annular groove part, reserving 0.02-0.03 millimeters of allowance for fine grinding, and carrying out coreless through grinding on the excircles of two flanges with the height of surplus outer diameter; the step of grinding the raceway and the flanges comprises: utilizing a coreless clamping apparatus to support the excircles of the flanges so as to carry out ground finish to reach the precision; and the step of carrying out fine grinding on the excircle comprises: carrying out coreless grinding on the excircle so that products are tested to achieve the required precision of a drawing. The grinding method provided by the invention has the advantages of safety, reliability, high efficiency and high precision, and can be used for solving the problem that the product quality is disqualified and the size is overproof, and therefore the product quality is seriously influenced.

Description

The method for grinding of a kind of thin wall type outer ring with holes
Technical field
The present invention relates to the processing method of a kind of thin wall type outer ring with holes, specifically, is the method for grinding of a kind of thin wall type outer ring with holes.
Background technology
Rolling bearing is that the axle of running and the sliding friction between the axle bed are become rolling friction, thus the mechanical organ of a kind of precision of the loss of reducing friction.Rolling bearing generally is made up of inner ring, outer ring, rolling element and retainer four parts, and the effect of inner ring is to match to merge with axle to rotate together with the axis; The outer ring effect is to match with bearing block, plays a supportive role; Rolling element is uniformly rolling element to be distributed between inner ring and the outer ring by means of retainer, and its shape size and quantity directly affect the serviceability and the life-span of rolling bearing; Retainer can make rolling element evenly distribute, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.Rolling bearing is accurate parts, and used part comprises that inner ring, outer ring, rolling element and retainer also all are accurate parts, and the processing request of accurate parts is very high, must study their processing method, just can reach required precision.Thin wall type outer ring with holes is exactly an example wherein.A kind of thin wall type outer ring; Porose and ring groove in the middle of its external diameter adopts penetration type processing in centreless grinding processing excircles process, because structure is slim and external diameter is with holes and groove; In process in the past; Because grinding process is discontinuous, surplus is irregular, so external diameter is oval big with deflection, and repeatedly ground effect is bad.All adopt electromagnetism centreless fixture support cylindrical because of the raceway grinding, cylindrical is bad can't to get into next step raceway grinding process, brings the defective and dimension overproof of product quality, has a strong impact on product quality.
Summary of the invention
The method for grinding of a kind of thin wall type of the present invention outer ring with holes, its objective is provides a kind of method for grinding safe and reliable, efficient, high-precision thin-walled lasso, solves the defective and dimension overproof of product quality, has a strong impact on the problem of product quality.
In order to achieve the above object, the present invention realizes through following technical scheme:
The present invention is the method for grinding of a kind of thin wall type outer ring with holes, comprises outer ring with holes, arranged outside second emery wheel and guide wheel in the outer ring; In the inboard of outer ring one the 3rd emery wheel is arranged, also be provided with annular groove on the outer ring, left rib and right rib; Said left rib and right rib lay respectively at the both sides of said outer ring, and said annular groove is positioned at the both sides up and down of said outer ring, and the present invention adopts first corase grind cylindrical, the substep method for grinding of regrind raceway and rib, last fine ginding cylindrical; Said corase grind cylindrical; Be to adopt cylindrical grinder to cut mill, grind off hole and ring groove part external diameter earlier, stay 0.02-0.03 millimeter surplus to wait to finish grind; Two rib cylindricals of inner round side are used the centreless through feed grinding outside grinding; Said grinding race and rib are to adopt centreless fixture support rib cylindrical cylindrical to carry out grinding to precision, said fine ginding cylindrical; Be to adopt the centreless grinding cylindrical, the multiparity article detect and reach the drawing requirement precision.
Further improvement of the present invention is: said centerless grinder is that clamping is not in the mood in the workpiece employing, generally is bearing between guide wheel and the carriage, drives the workpiece rotation by guide wheel, and the grinding machine that carries out grinding generally is the grinding cylindrical, also can the interior circle of grinding.
The present invention is safe and reliable, efficient, high accuracy, solves the defective and dimension overproof of product quality, has a strong impact on the problem of product quality.
