Abstract

The invention relates to a separating type flexibly driven spindle system for a high-precision processing machine tool, in order to solve the problems that a motor and a spindle of a spindle system in ultra-precision processing equipment are in rigid connection, a power transmission effect is inferior and the rotation precision of the spindle is influenced by the rigid connection. After an alternated current servo motor of the separating type flexibly driven spindle system is electrified, the alternated current servo motor starts to run so as to drive a flexible driving component to rotate, and a rotating torsion is generated by a driving lever under the driving of a flat belt which is rotated so as to drive the spindle to rotate and cut. High-pressure air enters from an axial air inlet, is throttled by a radial throttling hole, and then a radial air static pressure film is formed at a radial air film clearance by the high-pressure air; the radial air static pressure film is used for supporting the spindle and a radial load of the spindle; an axial air static pressure film is formed at an axial air film clearance by the high-pressure air after the high-pressure air is throttled by a first axial throttling hole; and the axial air static pressure film is used for supporting the spindle and an axial load of the spindle. The separating type flexibly driven spindle system provided by the invention is used for ultra-precision turning lathes and ultra-precision milling machines in various forms.

Description

technical field [0001] The invention belongs to the field of ultra-precision gas static pressure spindle systems, and in particular relates to a separate flexible drive high-precision machining machine spindle system. Background technique [0002] With the development of science and technology, the development of cutting-edge technologies such as national defense industry and microelectronics industry requires precision and ultra-precision machining equipment and technology, especially ultra-precision machining machine tools, which are the core and key of ultra-precision machining technology. The spindle system of the ultra-precision machining machine tool is the key component of the ultra-precision machining machine tool, and its precision directly affects the machining accuracy of the parts. Therefore, how to design and manufacture ultra-precision spindles has become the core and key of ultra-precision machining machine tools. The design of the spindle of an ultra-precisi...
