Ball head end surface grinding device used for tapered roller

Abstract

The invention relates to the field of bearing roller processing equipment, and discloses a ball head end surface grinding device used for a tapered roller. The grinding device comprises a rack, and afeed tooling and a cup-shaped grinding wheel capable of making feed movements in the feed tooling direction are arranged on the rack; the feed tooling comprises an upper pressing plate, an insulationplate and a lower pressing plate which are horizontally distributed are arranged on the rack, and a plurality of U-shaped grooves are formed in the periphery of the insulation plate at intervals; a first groove opening is formed in the periphery position of the lower pressing plate, and a shape correction platform is arranged below the first groove opening; a second groove opening corresponding tothe first groove opening is formed in the periphery of the upper pressing plate, a wheel frame capable of being lifted and lowered is arranged on the position, above the second groove opening, of therack, and a power wheel used for stirring a to-be-processed tapered roller on the shape correction platform to rotate is arranged at the lower end of the wheel frame; according to the device, accuracy and specification requirements to the feed tooling and the grinding wheel are lower, so that curvature radius range of the produced ball head end surface of the tapered roller is wider, and the quality is stable.

Description

technical field [0001] The invention relates to the field of bearing roller processing equipment, in particular to a ball head end face grinding device for tapered rollers. Background technique [0002] The processing of the end surface of the tapered roller ball head is an indispensable process in the processing of tapered rollers. At present, due to the influence of many factors such as processing equipment, feeding tooling system, grinding wheel, and operating skills, spherical grinding wheels are generally used in the through-grinding method for tapered roller ball end face grinding. [0003] The radius of curvature of the tapered roller ball head of this through-type grinding process is determined by the size of the feed tooling and the spherical radius of the spherical grinding wheel. The size of the feed tooling is too large, and the adjustment technology is difficult, which is not conducive to manufacturing; the spherical radius of the spherical grinding wheel requi...

AI Technical Summary

Problems solved by technology

The size of the feed tooling is too large, and the adjustment technology is difficult, which is not conducive to manufacturing; the spherical radius of the spherical grinding wheel requires high precision, and the spherical radius of the spherical grinding wheel needs to be continuously corrected during the end grinding process of the roller ball. The correction is difficult, the correction effect is unstable, and it is difficult to guarantee the consistency of the product
