Traditional lathe will realize rotation of the emery wheel in electro spindle axial direction, it is necessary to coordinate corresponding transmission system to realize, existing
There is feed system in technology mainly to have following two：
The first, is equipped with the transmission devices such as gear-box or belt pulley and realizes rotation of the emery wheel in electro spindle axial direction.
In the system, main shaft is contained in main spindle box, and electro spindle case is driven in electro spindle by transmission devices such as gear-box or belt pulleys
Axial direction rotates, and then realizes grinding workpiece, and its transmission accuracy is high, there is that operation is unstable, and noise is big, and vibrations are big, and
Cost is high, complicated；
Second, realized using built-in traditional induction machine executive component and directly drive emery wheel rotation, the feed system
The less High-speed machining situation of the stock removal that is particularly suitable for use in, low speed is exerted oneself not enough.In the transmission system, motor is contained in electric master
In axle box, volume is weighed greatly, axis rigidity is poor, is seriously constrained compact, precision machine tool high speed, the function of high fine ginding and is realized,
Although its cost is relatively low, wide permanent torque scope grinding can not be realized, while can cause to accommodate the main spindle box volume of electro spindle
Increase.
Utility model content
To overcome the defect that prior art is present, the utility model provides a kind of wide permanent torque scope surface-mount type permanent-magnet synchronous
Double end grinding electric main shaft.
The utility model solves the technical scheme that its technical problem used：
A kind of wide permanent torque scope surface-mount type permanent-magnet synchronous double end grinding electric main shaft, including main spindle box, main shaft, Surface Mount are provided
The rimless motor of formula permanent-magnet synchronous, the durface mounted permanent magnet synchronously rimless motor include durface mounted permanent magnet synchronously rimless motor stator with
And durface mounted permanent magnet rotor, the cylindrical of the main shaft be connected with durface mounted permanent magnet rotor, and motor is fixed built in the main spindle box and is determined
Son, synchronously rimless motor drives the main shaft to be rotated around the axis of the main shaft to the durface mounted permanent magnet, the durface mounted permanent magnet
Synchronous rimless motor stator, which is powered, produces rotating excitation field, and air gap is produced with durface mounted permanent magnet rotor permanent-magnetic field interaction
Rotating excitation field, when the air-gap rotating magnetic field that electric current cutting motor rotor magnetic linkage is produced in stator winding, will drive surface-mount type
P-m rotor drives main shaft rotation；The two ends end face of the main shaft is respectively connected with handle of a knife, for grinding knife tool；Outside the main shaft
After circle connection surface-mount type p-m rotor the first angular contact bearing and the second angular contact bearing are also respectively mounted in bearings at both ends position.
In such scheme, left inside end cap, left end cap are fixed with successively on the outside of described main spindle box one end, the main spindle box is another
End outside is fixed with right inner end cap, right end cap, outer end cap successively.
Implement the wide permanent torque scope surface-mount type permanent-magnet synchronous double end grinding electric main shaft of the utility model, with following beneficial effect
Really：
(1) the utility model is applied to high rigidity, wide permanent torque scope, the occasion of high-speed grinding.
(2) the utility model hangs on five axle tool grinding lathe C axles by main spindle box, synchronously rimless by durface mounted permanent magnet
Main shaft of the motor driving with double end grinding function, double end grinding is realized after installing emery wheel.
(3) electro spindle of the present utility model is compared with conventional motors electro spindle, increase by 50% of exerting oneself, and appearance and size reduces 2
Individual above seat No., weight saving reduces C thrust loads, and shafting diameter doubles the above, rigidity and conventional asynchronous motor
Main shaft is compared to more than 2 times, thus significantly shortening electro spindle Acceleration and deceleration time is improved, and in addition, durface mounted permanent magnet rotor does not generate heat, and turns
Sub- temperature is low, significantly reduces bearing heating, reduces main shaft thermal expansion, improves spindle processing precision, enhance electro spindle
Reliability.
