Main shaft for machine tool, machine tool, and method for preventing machine tool from being worn

Abstract

The invention discloses a main shaft for a machine tool, the machine tool, and a method for preventing the machine tool from being worn. A radial air bearing of the main shaft for the machine tool is supported in a main shaft box body, one end of the radial air bearing is connected with the end face of an air floating shaft on the front end face, and the other end of the radial air bearing is connected with the end face of an air floating shaft on the rear end face; a piston is connected with an air floating main shaft; an air floating main shaft piston is connected with a guiding chuck; a side floating disc is connected with the air floating main shaft; the air floating main shaft piston, a taper sleeve and the guiding chuck are connected onto the air floating main shaft; gas is contained in the main shaft. The main shaft for the machine tool is utilized, so that the problem that the main shaft of machine tool equipment in the prior art is mainly mechanically supported by the bearing, and the mechanical wear is severe can be solved; the occurrence of the phenomenon that the rotation stability of the main shaft gets worse along with the increase of processing time can be effectively prevented; the precision machining accuracy and the yield of the product are improved; the production efficiency is further improved remarkably and the production cost is reduced.

Description

Problems solved by technology

Relying on traditional manual or semi-automatic operation methods cannot meet the needs of the development of science and technology today. In the precision machining process of machine tools such as turning, milling, and grinding, the stability of the spindle rotation and the degree of wear of the spindle determine the quality of the parts. Precision Machining Accuracy

The main shaft of the machine tool equipment in the prior art is mainly supported by bearings, and there is serious mechanical friction and wear. With the increase of processing time, the stability of the main shaft rotation becomes worse, the precision machining accuracy of parts is difficult to meet the requirements, and the product qualification rate will decrease. As it decreases, the generation cost will further increase and other issues
