Gear grinding machine with numerical control forming grinding wheel

Abstract

The invention discloses a gear grinding machine with a numerical control forming grinding wheel; the grinding wheel comprises a stand which is provided with a horizontal sliding guide rail and a longitudinal sliding guide rail; a work piece rotary part is slidably assembled on the longitudinal sliding guide rail in a guiding way; a vertical column is slidably assembled on the horizontal sliding guide rail in a guiding way; and a grinding mechanism which is used for grinding a processed gear is slidably assembled on the vertical column in a guiding way along a vertical direction. The gear grinding machine with the numerical control forming grinding wheel also comprises a grinding wheel forming and finishing device which finishes a grinding wheel; the grinding wheel forming and finishing device comprises a finishing device base which is independently assembled on the vertical column above the grinding mechanism and a finishing wheel with the axis extending along a longitudinal direction; and the finishing wheel is slidably assembled on the sliding guide rail of a longitudinal finishing device of the finishing device base through a finishing wheel frame which extends outwards in a guiding way. According to the gear grinding machine with the numerical control forming grinding wheel, the problems of the prior art that the processing surface of the grinding wheel cannot be finished to be consistent with the shape of the gear slot of the processed gear, and the precise of the processing gear and the processing efficiency of the gear with a large specification are affected are solved.
