An inner surface processing device for bearings

Abstract

The invention relates to an inner surface machining device used for a bearing. The inner surface machining device comprises a first bottom plate, a machining support is welded to the middle of the upper end face of the first bottom plate, a machining supporting rod is mounted on the lower end face of the machining support, an abut-against arc plate is integrally molded at the lower end of the machining supporting rod, two positioning mechanisms are mounted on the front side and the rear side of the lower end face of the machining support, and a first bearing ring is mounted between the two positioning mechanisms and the abut-against arc plate; each positioning mechanism comprises a machining vertical plate welded to the lower end face of the machining support, a third hydraulic cylinder is mounted on the inner wall of each machining vertical plate, the top end of each third hydraulic cylinder is provided with a third flange through a thread, a positioning piece is mounted on each third flange through a screw, each third flange plays a role in connecting each third hydraulic cylinder and the corresponding positioning piece, the positioning pieces abut against the outer wall of the first bearing, and the middles of the third hydraulic cylinders are fixed to machining fixed plates; the device can achieve the automatic machining function of the inner surface of the bearing.

Description

technical field [0001] The invention relates to the technical field of bearing processing equipment, in particular to an inner surface processing device for bearings. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy; rolling bearings generally consist of outer rings, inner rings, rolling elements and holding The frame is composed of four parts, strictly speaking, it is composed of six parts: outer ring, inner ring, rolling element, cage, seal, and lubricating oil. Simply put, as long as it has an outer ring, an inner ring, and rolling elements, it can be defined as a rolling bearing. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. [0003] The main processing technology of the bearing is to process th...
