Abstract

The invention discloses a spindle cooling structure with annular cooling and axial cooling connected in series and a machine tool. The spindle cooling structure mainly comprises a spindle sleeve. A cooling loop on the spindle sleeve is formed by connecting two parts in series, namely a spiral groove cooling pipeline and axial hole cooling pipelines sequentially connected in series, and the two parts of pipelines are connected in series to form the circulating cooling loop. The cooling pipeline at the position of a spiral cooling groove and the cooling pipelines formed by connecting the multiple axial holes in series are connected in series to form the complete cooling loop, and cooling liquid entering the cooling loop flows in a circulating manner.

Description

technical field [0001] The invention relates to the technical field of machine tool spindle cooling, in particular to a spindle cooling structure and a machine tool in which the nose end of the machine tool spindle is as close as possible to a workpiece. Background technique [0002] With the rapid development of the manufacturing industry, the market has higher requirements for the performance of CNC machining centers, not only requiring high spindle speed, but also requiring small spindle temperature rise to maintain the machining accuracy of CNC machining centers. The CNC machining center drives the tool to rotate at high speed through the spindle to realize the machining of the workpiece. When the spindle rotates at high speed, on the one hand, the spindle drives the cutting tool to generate a lot of heat, and on the other hand, the high-speed rotation of the bearing also generates a lot of heat, which eventually causes the temperature of the spindle to rise; which in tu...
