Superfine head of double-row tapered roller bearing outer shell

Abstract

The invention relates to a grinding tool for a grinding machine tool, in particular to a superfine head of a double-row tapered roller bearing outer shell. According to the technical scheme of the invention, the superfine head of the double-row tapered roller bearing outer shell comprises a connecting plate and two groups of cylinders installed on the connecting plate, and the superfine head is characteristic in that each group of the cylinders is provided with a pressurizing cylinder and a jump-into and jump-out cylinder both of which are parallel arranged, a pressurizing piston rod of the pressurizing cylinder is connected with a compressive rod, and a tool carrier is arranged on a jumping piston rod of the jump-into and jump-out cylinder. A mechanism provided by the technical scheme can simultaneously process two roller paths, thus the positioning error of secondary positioning can be avoided and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a grinding tool for a grinding machine tool, in particular to a super-precision head of a double-row tapered roller bearing jacket. Background technique [0002] Since the two raceways of double-row tapered roller bearings (such as railway wagon bearings, second-generation automobile wheel bearings, etc.) form symmetrical conical surfaces, according to the current super-finishing method, it is necessary to super-finish one raceway first, and then turn around and super-finish The other raceway cannot superfine the two raceways at the same time or step by step. It not only causes repetition and cumbersome processing procedures, affects production efficiency, increases labor intensity of workers, but also seriously affects processing accuracy, which cannot meet the growing quality requirements of bearing manufacturing. Contents of the invention [0003] The purpose of the present invention is to design a double-row tapered roll...

Problems solved by technology

[0002] Since the two raceways of double-row tapered roller bearings (such as railway wagon bearings, second-generation automobile wheel bearings, etc.) form symmetrical conical surfaces, according to the current super-finishing method, it is necessary to super-finish one raceway first, and then turn around and super-finish Another raceway, unable to superfinish both raceways at the same time or step by step

It not only causes repetition and cumbersome processing procedures, affects production efficiency, increases labor intensity of workers, but also seriously affects processing accuracy, which cannot meet the growing quality requirements of bearing manufacturing.
