High speed spindle box structure

Abstract

The invention discloses a high speed spindle box structure, and belongs to the machine tool part device field. The high speed spindle box structure comprises a spindle box, a spindle device, a front bearing seat, a rear bearing seat, a spindle drive mechanism, a cooling system, a lubrication system and a dynamic balance regulating mechanism, wherein a spindle of the spindle device is supported by a front bearing component and a rear bearing component, and installed in a spindle hole in the spindle box, bearings of the front bearing component are two pairs of front ball bearings and rear ball bearings, which are arranged at a certain interval, bearings of the rear bearing component are roller bearings, the cooling system comprises a spindle cooling mechanism and a bearing cooling mechanism which respectively have functions of cooling the spindle and cooling the interiors of the bearings, and the lubrication system comprises a front bearing lubrication mechanism and a rear bearing lubrication mechanism, and respectively have functions of lubricating the front bearing component and lubricating the rear bearing component. The high speed spindle box structure solves the problems that an existing spindle box mechanism is poor in cooling effect, temperature of bearings of the existing spindle box mechanism easily rise, and then rotation speed and processing accuracy of the existing spindle box mechanism are influenced.
