Feed system in technology is had mainly to have following two：
The first, be equipped with the actuating devices such as gear-box or belt pulley and realize the rotation in electro spindle axial direction for the emery wheel.?
In this system, main shaft is contained in main spindle box, drives electro spindle case in electro spindle by actuating devices such as gear-box or belt pulleys
Axial direction rotates, and then realizes grinding work piece, and its transmission accuracy is not high, has that operation is unstable, and noise is big, and vibrations are big, and
High cost, complex structure；
Second, to realize directly driving emery wheel to rotate using built-in tradition induction machine executive component, this feed system
It is particularly suited for stock removal less High-speed machining situation, low speed is exerted oneself not.In this drive system, motor is contained in electric master
In axle box, volume weighs greatly, axis rigidity is poor, seriously constrains compact, precision machine tool high speed, the functional realiey of high fine ginding,
Although its cost is relatively low, wide permanent torque scope grinding cannot be realized, can cause to accommodate the main spindle box volume of electro spindle simultaneously
Increase.
Content of the invention
For the defect overcoming prior art to exist, a kind of present invention offer width permanent torque scope surface-mount type permanent-magnet synchronous double end
Grinding electric main shaft.
The technical solution adopted for the present invention to solve the technical problems is：
There is provided a kind of width permanent torque scope surface-mount type permanent-magnet synchronous double end grinding electric main shaft, including main spindle box, main shaft, Surface Mount
The rimless motor of formula permanent-magnet synchronous, described 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 described main shaft be connected with durface mounted permanent magnet rotor, and the built-in fixing motor of described main spindle box is fixed
Son, synchronously main shaft described in rimless Motor drive rotates described durface mounted permanent magnet around the axis of described main shaft, described durface mounted permanent magnet
Synchronous rimless motor stator energising produces rotating excitation field, interacts with described surface-mounted permanent magnet machine rotor permanent-magnetic field and produces
Air-gap rotating magnetic field, when the air-gap rotating magnetic field that electric current cutting motor rotor magnetic linkage in stator winding produces, will drive table
Mounted p-m rotor drives main shaft rotation；The two ends end face of described main shaft is respectively connected with handle of a knife, for grinding knife tool；Described main shaft
Cylindrical connection surface-mount type p-m rotor after be also respectively mounted the first angular contact bearing and the second angular contact axle in bearings at both ends position
Hold.
In such scheme, outside described main spindle box one end, it is fixed with left inside end cap, left end cap successively, described main spindle box is another
It is fixed with right inner end cap, right end cap, outer end cap successively outside end.
Implement width permanent torque scope surface-mount type permanent-magnet synchronous double end grinding electric main shaft of the present invention, have the advantages that：
(1) present invention is applied to high rigidity, wide permanent torque scope, the occasion of high-speed grinding.
(2) present invention hangs on five axle tool grinding lathe C axles by main spindle box, by durface mounted permanent magnet synchronously rimless motor
Drive the main shaft with double end grinding function, after emery wheel is installed, realize double end grinding.
(3) electro spindle of the present invention is compared with conventional motors electro spindle, increase by 50% of exerting oneself, overall dimensions reduce 2 with
Upper frame number, weight saving, reduce C thrust load, and shafting diameter doubles above, rigidity and conventional asynchronous electric machine main shaft
Compare more than 2 times of raising, thus significantly shorten electro spindle Acceleration and deceleration time, in addition, durface mounted permanent magnet rotor does not generate heat, rotor temperature
Degree is low, significantly reduces bearing heating, reduces main shaft thermal expansion, improves spindle processing precision, and enhance electro spindle can
By property.
