Abstract

The invention relates to a gas high speed electric spindle. The electric spindle performs precise processing on magnalium through utilizing a high speed cutting principle. The gas high speed electric spindle is characterized in that a spindle main body of water circulating cooling, an air bearing and a thrust bearing of water circulating cooling, a rotor core which can automatically disassemble a cutter, and a cylinder which can automatically disassemble a cutter device are arranged on the electric spindle, wherein the integral air bearing is mounted in the spindle main body; the rotor core is arranged between the air bearing and a stator; and a cutter pushing mechanism in the cylinder is arranged in the rotor core and does not rotate along with the rotor core when the rotor core rotates, the laterality of the spindle during rotation is reduced, the service life of the spindle is guaranteed, the processing difficulty of the spindle is reduced, and the production is facilitated.

Description

technical field [0001] The invention relates to machining equipment, in particular to an air-floating high-speed electric spindle used for precise machining of magnesium and aluminum alloys. Background technique [0002] In the prior art, the main shaft assembly for the air-floating electric main shaft uses an aluminum water jacket, which has a complex structure and is not conducive to heat dissipation. During use, the product is easily deformed and the main shaft is unstable. The air bearing adopts a split structure, which reduces the machining accuracy of the bearing. There is no annular cooling water channel on the outer circle of the bearing, which is prone to heat, high internal temperature, and easy to cause the spindle to be stuck. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an air-floating high-speed electric spindle. [0004] In order to solve the above t...
