Bearing outer ring double-groove one-time grinding process and equipment

Abstract

The invention discloses a bearing outer ring double-groove one-time grinding process and equipment, and belongs to the technical field of bearing machining. The defects that in existing bearing outer ring double-groove grinding machining, as the positions of two grooves are asymmetric, equipment needs to be adjusted after one groove is ground, then another groove is machined, the machining efficiency si low, and the relative accuracy of the two grooves cannot be guaranteed are overcome. According to the scheme, the equipment comprises a machine frame, a fixed plate is installed at the top of one end of the machine frame, a chuck is installed on the fixed plate, a movable frame is installed at the top of the other end of the machine frame, a movable seat is clamped between the inner walls of the movable frame, a cutter feeding assembly is installed among the movable seat, the machine frame and the movable frame, a grinding motor is installed on the movable seat, an output shaft of the grinding motor penetrates through the movable seat and is provided with a double-grinding-wheel mechanism, a hanging bracket is fixedly installed on the machine frame between the fixed plate and the movable seat, and a dresser is installed on the hanging bracket. Two grinding wheel discs are dressed before grinding, it is ensured that the distance meets the requirement for the distance between double grooves, the machining efficiency is improved through one-time grinding, and the machining precision is ensured.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a double groove primary grinding process and equipment for the outer ring of a bearing. 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 (friction coefficient) during its movement, and ensure its rotation accuracy. The inner wall of the outer ring of the double-groove bearing is provided with two grooves for rolling elements. The following deficiencies exist in the double-groove grinding process of the bearing outer ring: [0003] 1. Due to the asymmetric position of the two grooves, the equipment can only be adjusted after grinding one groove first, and the other groove is processed, resulting in low processing efficiency; [0004] 2. If the two grooves are processed separately, the relative accuracy between the two grooves ca...
