Abstract
The utility model belongs to the technical field of a numerical controlled machine tool, and relates to a simplified numerical controlled grinder head rack. A rear bearing sleeve is fixed at one end of a head rack shell, and a front positioning sleeve is fixed at the other end of the head rack shell. A centre hole is arranged on the front positioning sleeve, and a through hole coaxial to the centre hole is arranged on the rear bearing sleeve. A centre is arranged in the centre hole, and one end of a screw passes through the through hole on the rear bearing sleeve, inserts into the centre hole on the front positioning sleeve and is threaded on the centre. The centre of head rack is assembled in the head rack shell via a front positioning sleeve and a rear bearing sleeve. The head rack is low in manufacture cost, simple in assembling, and high in precision, and is applicable to various machine tools.
