Background
The electric main shaft is a new technology which integrates a machine tool main shaft and a main shaft motor into a whole and appears in the field of numerical control machines, and the electric main shaft comprises a shell-free motor, a main shaft, a bearing, a main shaft unit shell, a driving module, a cooling device and the like. The rotor of the motor is integrated with the main shaft by adopting a press-fit method, and the main shaft is supported by the front bearing and the rear bearing; the stator of the motor is often installed in a shrink fit interference mode, and in order to ensure shrink fit interference, the spindle housing needs to be heated to about 200 degrees, so that the spindle housing is very easy to deform seriously, inconvenience is brought to spindle installation, and spindle assembly precision is further influenced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides an effectively ensure electric spindle motor stator mounting structure of main shaft installation accuracy.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an electricity spindle motor stator mounting structure, includes main shaft housing, stator and rotor, and the rotor supports through the bearing at its pivot both ends and installs in main shaft housing center, the stator includes stator core, the embedded winding coil in stator core both ends, and stator core periphery interference fit has the carbon fiber pipe, main shaft housing step hole has, the step face in tight step hole is pasted to stator core medial surface, stator core outside terminal surface links firmly the iron core fixed plate, the step hole transition fit of carbon fiber pipe periphery and main shaft housing, the main shaft housing terminal surface that is located the step hole side is equipped with stator locking plate, link firmly through connecting bolt between stator locking plate and the iron core fixed plate and make stator locking plate compress tightly at main shaft housing terminal surface.
Furthermore, a cavity formed between the stator core and the carbon fiber tube is filled with insulating epoxy glue.
Preferably, in order to improve the connection strength, the stator locking plate is fixedly connected with the iron core fixing plate through twelve circumferentially and uniformly distributed connecting bolts.
The utility model has the advantages that: the utility model discloses change traditional heating interference fit between stator core and the main shaft housing into transition fit, link firmly stator locking plate and iron core fixed plate through connecting bolt for stator core links into wholly with main shaft housing, has both prevented the race circle phenomenon that stator core appears when the high-speed operation of electricity main shaft, has avoided again because heating assembly causes main shaft housing to appear warping, has ensured the assembly precision of main shaft and the moment of torsion of motor work output effectively.
