Method for planishing, grinding and processing surface of special type bearing ring ball race

Abstract

The invention relates to a processing method for finishing and grinding the raceway surfaces of special type bearing rings, which comprises the followings steps: on the basis that the processed structural shape that the inner ring is provided with a flange and the outer ring is provided with a cambered surface is designed with a corresponding convex groove guide roll 1 or a cambered surface guideroll 13 and an oilstone clamp; in the processing, firstly, fixing the oilstone clamp on a connecting block 11 through inner bolts; secondly, mounting the processed special type bearing rings 2 to corresponding positions on front and back convex grooves or cambered surface guide rolls one by one; and thirdly, adjusting the surface contact pressure between a grinding block 3 on the oilstone clamp and the inside diameter or the outside diameter of the processed special type bearing rings, and starting a driving device of a common outside diameter grinding machine to cause the front and back convex grooves or cambered surface guide rolls to rotate actively and drive all the processed special type bearing rings to rotate and perform the processing of finishing and grinding, wherein coal oil doped with a small amount of engine oil can be poured to grinding areas for a few times in the whole process of finishing and grinding so as to clear out scrap iron and grinding block foam and increase the grinding effect. The method can grind six of the processed special type bearing rings once, thereby improving the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of bearing processing, and in particular relates to a method for finishing and grinding the raceway surface of a special bearing ring. Background technique [0002] The surface quality of the bearing ring raceway directly affects the working performance and service life of the bearing. When grinding bearing rings, due to the precision, vibration, deformation and high productivity of the grinding machine, the surface quality of the raceway is difficult to meet the requirements of surface roughness and geometric shape accuracy. Therefore, after the surface grinding of the rolling body of the ferrule, it is generally necessary to carry out finishing processing, so as to improve the roughness of the raceway surface, reduce the roundness error, improve the geometric shape accuracy of the raceway surface, and improve the mechanical and physical properties of the raceway surface, etc. . [0003] At present, there...

Problems solved by technology

[0004] The common features of the above-mentioned common finishing methods are: when the grinding machine is working, not only the workpiece rotates with the guide roller, but also needs to be fed axially, or the oscillating movement of the grinding head. The finishing process is still more applicable, but for such as figure 1 Inner ring with ribs, figure 2 It is not suitable for raceway processing of special bearing rings with arc surface on the outer ring. The main problem is the inconvenience of clamping and grinding caused by the complexity of the shape of special bearing rings.
