Adjusting device for center height of numerical control generating grinding head

Abstract

The invention discloses an adjusting device for the center height of a numerical control generating grinding head. The device comprises a fixed support, a generating grinding head seat, a rotating shaft, a generating grinding head, a servo motor, an eccentric shaft, a grinding head motor and an eccentric shaft adjusting seat. The fixed support is fixed on a dragging plate, the generating grinding head seat is installed on the fixed support, the generating grinding head is fixed on the generating grinding head seat, the generating grinding head seat is connected through the rotating shaft and can rotate around the rotating shaft, the servo motor is fixed on the generating grinding head seat, an output shaft of the servo motor is connected with one end of the eccentric shaft through a coupler, the other end of the eccentric shaft is installed on the generating grinding head seat through a bearing, and the grinding head motor is fixed on the dragging plate. An output shaft of the grinding head motor is connected with the generating grinding head seat through a belt. According to the technical scheme, the servo motor is adopted to drive the eccentric shaft, and the eccentric shaft drives the generating grinding head seat to swing up and down, so that the center height adjustment of the generating grinding head is realized, the labor intensity is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a device for adjusting the center height of a bearing fan grinding machine, which is particularly suitable for grinding the inner and outer ring raceways of self-aligning roller bearings ground by fan grinding. Background technique [0002] For the grinding of inner and outer ring raceways of spherical roller bearings, cross patterns need to be ground, so that the center height of the fan grinding head is required to coincide with the center height of the workpiece. The existing bearing grinding uses fan grinding The heads are all adjusted, and the mechanical structure is mostly adjusted by adjusting screws, which need to be adjusted during processing. This method is inefficient, risky, and increases the strength of the laborer. Contents of the invention [0003] The task of the present invention is to propose a device for adjusting the center height of a numerically controlled fan-shaped grinding head without manual adjustme...
