For a kind of outer water cooling electro spindle.
The deficiency of the utility model to solve above-mentioned technical problem, used technical solution are：
A kind of outer water cooling electro spindle, including shaft are mounted on bearing on the both ends of shaft, wherein being arranged in an end bearing
There is bearing block, shell is arranged in another end bearing, wherein one end of shell is axially extending along shaft and top is located on bearing block,
It is additionally provided with mutually matched rotor and stator in the space that shaft and shell surround, spiral water is offered on the lateral wall of shell
Cold trap, hull outside are covered with spindle box, and encapsulation process, the lateral wall of shell are done between main shaft chamber interior wall and the lateral wall of shell
On spiral water cold trap cooperation main shaft chamber interior wall constitute spiral water-cooling chamber, offer cooling water inlet on spindle box and cooling water go out
Mouthful, cooling water inlet and cooling water outlet be connected to spiral water cold trap, and spiral water-cooling trench bottom offers the first blind hole, the
One blind via bottom opens up that there are one the threaded holes for running through shell, the second blind hole is offered on the excircle of stator, threaded hole is fixed
It projecting and is fallen in the second blind hole on the excircle of son, twist and set there are one screw in threaded hole, screw head is sunk in the first blind hole,
The one end of screw far from head is plugged in through threaded hole in the second blind hole, is folded between screw head and the first blind via bottom
Sealing ring.
The screw uses cross recess fillister head screw.
The sealing ring uses O-ring seal.
Second blind hole is a flat-bottom slot.
It is pressed into O-ring seal between screw major part position and first blind hole on threaded hole top, when screw screws, O
Type sealing ring compressive deformation, threaded hole oral area is shut completely；Stator holding portion is to be revolved simultaneously by cross recess fillister head screw
It is fashionable, in the second blind hole of the small column head end indentation stator outer diameter corresponding position of screw, realize stator circumference direction and axial direction
Fixation.
Electro spindle is packed into lathe headstock bore, is passed through cooling water, and electro spindle is made to operate, cooling water is by O-shaped close
The barrier of seal can not flow into inside main shaft, achieve the purpose that waterproof.Meanwhile the cylinder head end of cross recess fillister head screw
In second blind hole of embedded stator outer diameter, stator is locked, fixed purpose has been reached.
The utility model has the beneficial effects that：First, head of screw is less than spiral water cold trap, maintains the complete of circulation waterway
Property, keep flow unobstructed；Second, element used in the structure is all standing standard component, is easy purchase and replaces, at low cost；Third,
This is simple in structure, assembling easy to disassemble；4th, it is flat-bottom slot that the second blind hole is opened up on stator, and stator will not when spindle operation
Circle is run to loosen, it is fixed.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is stator fixed form schematic diagram in the utility model.
Diagram label：1, shaft, 2, shell, 3, rotor, 4, stator, 5, screw, 6, sealing ring, 7, spindle box.
Specific implementation mode
As shown in the figure, specific implementation mode is as follows：
A kind of outer water cooling electro spindle, including shaft 1 are mounted on bearing 8 on the both ends of shaft 1, wherein in an end bearing 8
It is arranged with bearing block, shell 2 is arranged in another end bearing 8, wherein one end of shell 2 is axially extending along shaft 1 and top is located at
On bearing block, mutually matched rotor 3 and stator 4, the lateral wall of shell 2 are additionally provided in the space that shaft 1 and shell 2 surround
On offer spiral water cold trap, 2 outside mask of shell is equipped with spindle box 7, is done between 7 inner wall of spindle box and the lateral wall of shell 2 close
Envelope is handled, and spiral water cold trap cooperation 7 inner wall of spindle box on the lateral wall of shell 2 constitutes spiral water-cooling chamber, is opened up on spindle box 7
There are cooling water inlet 101 and cooling water outlet 102, cooling water inlet 101 and cooling water outlet 102 to connect with spiral water cold trap
Logical, spiral water-cooling trench bottom offers the first blind hole, opens up that there are one the threaded hole for running through shell, stators in the first blind via bottom
The second blind hole is offered on 4 excircle, threaded hole is projected on the excircle of stator and fallen in the second blind hole, is twisted in threaded hole
If there are one screw 5, screw 5 uses cross recess fillister head screw, 5 head of screw to sink in the first blind hole, and screw 5 is far from head
One end be plugged in the second blind hole through threaded hole, second blind hole is a flat-bottom slot, 5 head of screw and first blind
Sealing ring 6 is folded between the bottom of hole, sealing ring 6 uses O-ring seal.
Cross recess fillister head screw cooperation O-ring seal ensure that sealing avoids cooling water leakage, specifically electric
Be machined with radial screw bore and the first blind hole in main shaft housing, the head and 2 first blind hole of shell of cross recess fillister head screw it
Between be put into O-ring seal, when cross recess fillister head screw screws, O-ring seal compressive deformation seals threaded hole oral area completely
Extremely, coolant liquid can not invade inside electro spindle；4 fixed part of stator is the circle of screw when being screwed in by cross recess fillister head screw
The second blind hole that column cap side pressure enters 4 outer diameter corresponding position of stator is a flat-bottom slot, realizes stator 4 circumferentially and axially
It is fixed.
When spindle box is passed through cooling water, cooling water flows into 2 outer surface of shell, flows through 2 spiral water cold trap of shell, finally flows
Go out spindle box, realizes the purpose of electro spindle cooling.At this point, cooling water is full of in spiral water cold trap, due to cross recess socket cap spiral shell
There are the barrier of O-ring seal 6, cooling water to be isolated in 4 outside of stator between nail and stator 4；When electro spindle rotor 3 rotates, stator 4
On by negative direction turning moment, since cross recess fillister head screw is in tight condition, head of screw is pressed on stator 4
In second blind hole so that stator 4 can not move both axially and radially, and 4 moment of stator is in stationary state, and it is tight to realize stator 4
Solid purpose.
