Description

The internal fastening type cooling structure of electro spindle stator
Technical field
The utility model belongs to the cooling structure of motor, more specifically relates to a kind of internal fastening type cooling structure of electro spindle stator.
Background technology
Stator in electro spindle can produce very large heat when it runs, and generally all must design specialized structure and cool stator, coolant is water or oil.And traditional cooling structure is all to design cooling duct at stator exterior, a lot of parts and processing cost can be increased like this, most importantly the volume of product and weight is made to increase a lot, and due to the growth along with service time, corrosion and rubbish can be produced in cooling duct, thus blocking cooling duct, cannot carry out again dredging and can only renewal part.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of electro spindle stator carrying built-in cooling structure.
In order to obtain above-mentioned technique effect, the technical solution of the utility model is as follows:
The internal fastening type cooling structure of electro spindle stator, comprise front end housing, stator core, stator winding and rear end cap, stator winding winding is on stator core, the two ends of stator core are respectively equipped with front end housing and rear end cap, are equipped with cooling water pipe in stator core, and cooling water pipe is copper tube, front end housing is provided with cooling medium inlet and coolant outlet, cooling water pipe exports with coolant with cooling medium inlet respectively and is connected, and rear end cap is provided with cooling duct, and cooling water pipe is communicated with cooling duct.
In some embodiments, stator core and front end housing are tightly connected by front connector, and stator core and rear end cap are tightly connected by rear connectors.
Its beneficial effect is: 1, cooling structure is built in stator by the utility model, eliminate the external refrigeration structure of stator, the stator of the utility model comparable band external refrigeration structure in same unit volume situation is exported at power, moment of torsion increases by more than 30%;
2, coolant of the present utility model directly circulates in stator core inside, and cooling effect is more superior;
3, the copper tube as cooling water pipe closely penetrates in stator core, adds the integral rigidity of stator core;
4, the utility model eliminates external refrigeration structure, more simple when Installing machine tool, convenient;
5, dredging process can be carried out after adopting the utility model structure at any time, extend its useful life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the internal fastening type cooling structure of the electro spindle stator of the utility model one execution mode.
The title of the corresponding component in figure represented by numeral:
1. connector, 52. rear connectors before front end housing, 11. cooling medium inlets, 12. coolant outlets, 2. stator core, 21. cooling water pipes, 3. stator winding, 4. rear end cap, 41. cooling ducts, 51..
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
The utility model provides a kind of internal fastening type cooling structure of electro spindle stator, comprises front end housing 1, stator core 2, stator winding 3 and rear end cap 4.Stator winding 3 winding is on stator core 2, and the two ends of stator core 2 are respectively equipped with front end housing 1 and rear end cap 4.Be provided with many cooling water pipes 21 in stator core 2, cooling water pipe 21 is copper tube.Copper tube is closely located in stator core 2, adds the integral rigidity of stator core 2.Coolant circulates in cooling water pipe 21, and namely coolant is directly in the flowing of stator core 2 inner loop, and cooling effect is better.Front end housing 1 is provided with cooling medium inlet 11 and coolant outlet 12, and cooling water pipe 21 exports 12 with cooling medium inlet 11 and coolant respectively and is connected.Be provided with cooling duct 41 in rear end cap 4, cooling duct 41 is connected with cooling water pipe 21.Stator core 2 and front end housing 1 are tightly connected by front connector 51, and stator core 2 and rear end cap 4 are tightly connected by rear connectors 52.The Packed effect of junction tool of front connector 51 pairs of cooling water pipes 21 and front end housing 1, the Packed effect of junction tool of rear connectors 52 pairs of cooling water pipes 21 and rear end cap 4.In the electro spindle stator course of work, coolant is input into cooling water pipe 21 from cooling medium inlet 11 constantly, through cooling duct 41, exports 12 discharge, for electro spindle stator cools by coolant.
Above-described is only the preferred implementation of the internal fastening type cooling structure of the utility model electro spindle stator; not thereby the scope of the claims of the present utility model is limited; every the utility model specification and accompanying drawing content of utilizing makes equivalent structure transformation; or be directly or indirectly used in other relevant technical fields, be all in like manner included in protection range of the present utility model.
