Description
Technical field
The invention belongs to the cooling structure of motor, is more particularly to a kind of internal fastening type of electro spindle stator
Cooling structure.
Background technology
Stator in electro spindle can produce very big heat when which runs, and typically must all design specially
Cooling down to stator, cooling medium is water or oil to door.And traditional cooling structure is all
Cooling duct is designed in stator exterior, can so increase a lot of parts and processing cost, most main
Wanted is that to increase the volume of product and weight a lot, and due to the growth of use time,
Corrosion and rubbish can be produced in cooling duct, so as to block cooling duct, cannot be dredged again and
Can only renewal part.
Content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of electricity for carrying built-in cooling structure
Motor stator.
In order to obtain above-mentioned technique effect, technical scheme is as follows:
The internal fastening type cooling structure of electro spindle stator, including drive end bearing bracket, stator core, stator winding
And rear end cap, stator winding around being located on stator core, stator core be respectively arranged at two ends with front end
Lid and rear end cap, are equipped with cooling tube in stator core, cooling tube is copper tube, sets on drive end bearing bracket
There are cooling medium inlet and cooling medium outlet, cooling tube is situated between with cooling medium inlet and cooling respectively
Matter outlet is connected, and rear end cap is provided with cooling duct, and cooling tube is connected with cooling duct.
In some embodiments, stator core is tightly connected by front connector with drive end bearing bracket, fixed
Sub- iron core is tightly connected by rear connectors with rear end cap.
Its advantage is：1st, the present invention is built in cooling structure in stator, eliminates stator
Outside cooling structure so that the present invention is than the outside cooling knot of band in the case of same unit volume
The stator of structure increases by more than 30% in power, torque output；
2nd, the cooling medium of the present invention is directly to be circulated inside stator core, and cooling effect is more
For superior；
3rd, the copper tube as cooling tube is closely penetrated in stator core, increased the whole of stator core
Body rigidity；
4 present invention eliminates outside cooling structure, more simple in Installing machine tool, convenient；
5th, dredging process can be carried out at any time using after present configuration, extends its service life.

Cooling tube 21 is copper tube.Copper tube is closely located in stator core 2, increased stator core 2
Integral rigidity.Cooling medium is circulated in cooling tube 21, i.e., cooling medium is directly in stator
2 inner loop of iron core flows, and cooling effect is preferable.Drive end bearing bracket 1 is provided with 11 He of cooling medium inlet
Cooling medium outlet 12, cooling tube 21 export 12 phases with cooling medium inlet 11 and cooling medium respectively
Connection.Cooling duct 41 is provided with rear end cap 4, cooling duct 41 is connected with cooling tube 21.Stator
Iron core 2 is tightly connected by front connector 51 with drive end bearing bracket 1, after stator core 2 is passed through with rear end cap 4
Connector 52 is tightly connected.Junction of the front connector 51 to cooling tube 21 with drive end bearing bracket 1 has sealing
Effect, rear connectors 52 have Packed effect to the junction of cooling tube 21 and rear end cap 4.Electricity
In the motor stator course of work, cooling medium is constantly input into cooling tube 21 from cooling medium inlet 11
In, through cooling duct 41, discharged by cooling medium outlet 12, be that electro spindle stator cools.
The side of being preferable to carry out of the above-described internal fastening type cooling structure for being only electro spindle stator of the present invention
Formula, not thereby limits the scope of the claims of the present invention, in every utilization description of the invention and accompanying drawing
Hold and equivalent structure transformation is made, or other related technical fields are directly or indirectly used in, all same
Reason is included within the scope of the present invention.
