Abstract

The invention relates to a clearance adjusting structure of a main shaft of a high-precision numerical control drill, in particular to a main shaft structure suitable for numerical control drilling machine, which belongs to the technical field of machine devices. The clearance adjusting structure is characterized in that the clearance adjusting sleeve is mounted in a conical trepan boring, a screw is screwed on and screwed into a clearance adjusting grooving to form a combined unit, the combined unit is mounted in the trepan boring of the main shaft and fixed through a screw bolt, a flat gasket and a spring washer, the main shaft component is mounted into the main shaft seat and the clearance adjusting trepan boring, a clearance adjusting nut is screwed to adjust the clearance, and a pressure plate is used for fixing the position of the clearance adjusting nut through the screw bolt, the flat gasket and the spring washer. The invention has the advantages that the structure is reasonable, the fabrication is convenient, the manufacturability is strong and the positioning accuracy is high; in the practical drilling hole of the numerical control drill, the radial run-out of the main shaft is small, the drilling is stable and the drilling precision is high; therefore, the accuracy class of the numerical control drilling machine can be enhanced, and the application range of the numerical control drilling machine can be widened.

Description

technical field [0001] The invention relates to a gap adjustment structure of a high-precision CNC drilling spindle, in particular to a spindle structure suitable for a CNC drilling machine, and belongs to the technical field of mechanical equipment. Background technique [0002] In the existing technology, the positioning guide of the CNC drilling shaft is completely processed by gold to ensure the gap between the shaft and the shaft sleeve, which cannot be adjusted. Grade down. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a high-precision CNC drilling spindle clearance adjustment structure, which can ensure the best sliding fit between the spindle and the spindle sleeve, high positioning accuracy, small radial runout of the spindle, and Improve the accuracy level of CNC drilling machines. [0004] According to the technical solution provided by the present invention, the clearance adju...
