The invention discloses a built-in electric spindle which is convenient for disassembly and maintenance. The present invention includes housing, optical shaft, front bearing, rear bearing, stator, rotor, valve control mechanism and atomizing mechanism components, one end of the optical shaft protrudes from the housing and is rotationally connected with the housing, and the front bearing and the rear bearing are aligned with the optical shaft. It plays a supporting role. The optical axis is fixedly connected to the rotor in the middle of the line where it contacts the front bearing and the rear bearing. The stator is fixed inside the housing. The center line of the rotor perpendicular to the axis coincides with the center line of the stator perpendicular to the axis of the optical axis. Fog The valve control mechanism is located in the housing and connected to the optical shaft, and the valve control mechanism is rotatably connected to one end of the optical shaft close to the rear bearing. In the present invention, an atomizing mechanism is provided inside the electric spindle to lubricate the bearings with oil mist, and a centrifugal mechanism is provided inside the optical axis to connect with a valve control mechanism, which can control the change of the oil injection amount of the electric spindle while the rotating speed changes during operation. , effectively saving the amount of lubricating oil and prolonging the service life of the optical shaft.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to a built-in electric spindle which is convenient for disassembly and maintenance. Background technique [0002] The electric spindle is a new technology in the field of CNC machine tools that integrates the machine tool spindle and the spindle motor. The electric spindle has the advantages of compact structure, light weight, small inertia, low noise, and fast response. It also has high speed and high power. Simplified Machine tool design. In the prior art, the electric spindle will generate a lot of heat during operation. At the same time, if the lubrication between the bearing and the shaft is not enough, the optical shaft will not run smoothly, and the optical shaft will be worn to a certain extent, which will affect the service life of the electric spindle. Contents of the invention [0003] The object of the present invention is to provide a built-in electric spindle that...
