Processing method for internal sphere of split bearing seat

Abstract

The invention discloses a processing method for an internal sphere of a split bearing seat. The processing method comprises the following steps: installing a positioning mechanism on a workpiece shaft; fastening the bearing seat in the positioning mechanism; compacting the bearing seat on a transition plate through a press block; vertically arranging a positioning block on the transition plate and making the positioning block push against the bearing seat, taking a contact face between the positioning block and the end face of the bearing seat as a positioning face so as to ensure the degree of symmetry between the center of the internal sphere of the bearing seat and two end faces vertical to a key groove at the bottom face of the bearing seat; installing an angle positioning plate on a machine tool carriage; installing a grinding mechanism on the angle positioning plate and forming a grinding included angle between a grinding head of the grinding mechanism and the internal sphere of the bearing seat; swinging a first hand shank and a second hand shank to make the internal sphere of the bearing eat contact the grinding head; and starting a machine tool motor and a motor, so as to reversely rotate the bearing seat and the grinding head until the processing on the internal sphere of the bearing seat ends. With the adoption of the processing method provided by the invention, the internal sphere of the split bearing seat can be grinded, and the high-precision positioning for the center of the internal sphere of the bearing seat can be realized.

Description

technical field [0001] The invention relates to a processing method for a bearing seat, in particular to a processing method for splitting the inner spherical surface of the bearing seat. Background technique [0002] In the steelmaking and continuous casting production lines of iron and steel enterprises at home and abroad, split bearing housings and bearings are generally arranged in the middle of the integral driving roll of the continuous casting machine segment. The structure of the split bearing housing is relatively complicated, mainly composed of inner spherical bearing base, Bearing upper seat, half outer spherical outer ring, a split combined inner ring, a set of long cylindrical rollers, split sealing ring, sealing ring and other components. There are two independent systems inside the split bearing seat: cooling system and lubrication system, so the split bearing seat is also called water-cooled bearing seat. The basic features of the split bearing seat are:...

AI Technical Summary

Problems solved by technology

Therefore, once the split bearing seat and split bearing are damaged, they can only be scrapped. Imported new split bearing seats and split bearings are purchased, and the imported split bearing seats and split bearings are expensive, which increases the domestic steel industry. production cost of the enterprise
