Abstract

The invention discloses a high-precision numerical-control centerless machine tool spindle. The high-precision numerical-control centerless machine tool spindle comprises a spindle engine body, a central spindle, a bearing component, a right end cover and a driving wheel, wherein one end of the spindle engine body is fixed on a machine tool through a fixing part, and the other end of the spindle engine body is locked on the machine tool through a spindle locking block; the bearing component is sleeved on the central spindle, and the spindle engine body is sleeved on the bearing component; the bearing component comprises a first bearing pack, a bearing distance sleeve and a second bearing pack which are sleeved on the central spindle in sequence and in parallel; a first step and a bearing locking block propped against the bearing component are respectively arranged at two ends of the bearing component; the right end cover is sleeved on the central spindle and fixed on the right end face of the spindle engine body; a stop block propped against the first bearing pack is arranged on the right end cover; a convex wall is arranged on the inner wall of the spindle engine body, the right end of the convex wall is propped against the left end face of the first bearing pack, and the left end of the convex wall is in clearance fit with the right end face of the second bearing pack. The high-precision numerical-control centerless machine tool spindle disclosed by the invention has the characteristics of high precision, stable high-speed operation, and long service life.

Description

technical field [0001] The invention relates to the field of high-precision and high-efficiency numerical control machining, in particular to a main shaft of numerical control machining equipment used in turning, drilling, boring, engraving and other occasions of metal and non-metal materials. Background technique [0002] CNC centering automatic lathe equipment is an economical compound machine tool for turning, drilling, boring, engraving, etc. It can meet the requirements of multiple compound processing processes in one clamping, and is mainly used for high-precision small-scale batches of hardware parts and shafts with special-shaped batches. Parts and other processing belong to precision machining CNC equipment. In the early days, this type of equipment was mainly used in the precision processing industry of military equipment. With the continuous development of industrialization, in order to meet the market demand, this type of equipment is gradually applied to the pro...
