AI Technical Summary

Problems solved by technology

During the high-speed rotation of the spindle, the bearing will generate high temperature. If the bearing temperature is too high, it will not only affect the machining accuracy of the workpiece, but also cause carbonization of the grease in the bearing, which will affect the service life of the bearing.

Abstract

The invention discloses a spindle cooling mechanism and a machine tool. The spindle cooling mechanism includes a spindle box and a main cooling pipeline, the spindle box is provided with a spindle through a bearing, and the main cooling pipeline is arranged around the bearing. On the spindle box, the main cooling pipeline is provided with a plurality of secondary cooling pipelines extending axially and / or radially along the main shaft, and both ends of the secondary cooling pipelines are connected to the main cooling pipeline . According to the main shaft cooling mechanism and the machine tool of the embodiment of the present invention, the bearing on the main shaft can be cooled to ensure that the temperature of the bearing is within an appropriate range, and the machining accuracy of the workpiece will not be affected due to the high temperature of the bearing, and at the same time, it will not cause The carbonization of grease in the bearing will affect the service life of the bearing.

Description

technical field [0001] The invention relates to a machine tool, in particular to a main shaft cooling mechanism and the machine tool. Background technique [0002] Machine tools are one of the commonly used equipment for machining. There are many types. For example, gear grinding machines and gear milling machines are commonly used machine tools for gear processing. Both gear grinding machines and gear milling machines are equipped with spindles, such as tool spindles and workpiece spindles. , a tool is installed on the tool spindle, and a workpiece is installed on the workpiece spindle. The main shaft is generally installed on the machine tool through bearings. Specifically, the machine tool is provided with a headstock, and the main shaft is installed on the headstock through the bearings. During the high-speed rotation of the spindle, the bearing will generate high temperature. Excessive bearing temperature will not only affect the machining accuracy of the workpiece, bu...
