In equipment.Punching comes out mounting hole on usual electric machine iron core directly on stator punching, and punching is laminated into iron core, this
For kind iron core processing method since marker method is unreasonable, the utilization rate of silicon steel material is low.In order to solve problem above, injection moulded stator
It is applied and is promoted, injection moulded stator in the fabrication process, first manufactures the stator core without mounting hole, after completing wiring,
Mounting hole is formed by being moulded on motor.
In some equipment, the verticality of flatness and mounting hole axis to end face at motor installing hole is required very
Height, while mounting hole being required to have certain intensity, the mounting hole that injected plastics material is formed is unable to satisfy requirement, long time running and
Vibration can be such that the assembly precision of motor reduces.
Utility model content
The technical problems to be solved in the utility model and the technical assignment of proposition be prior art is carried out improve with
It improves, the injection moulded stator with adapter sleeve is provided, to improve the intensity of injection moulded stator mounting hole, while guaranteeing that the flat of hole end surface is installed
For the purpose of the verticality of face degree and mounting hole axis.For this purpose, the utility model takes following technical scheme.
Injection moulded stator with adapter sleeve, comprising:
Core body；
Adapter sleeve, set on the outside of core body, adapter sleeve opens up the mounting hole parallel with core body axis；
Core body and adapter sleeve are rolled into an entirety by injection molding part.
By the way that mounting hole is set on adapter sleeve, then by injection molding part and core body integrated through injection molding, improve note
Structural strength at modeling stator mounting hole can effectively ensure that the flatness of mounting hole endface after motor long-play
And the verticality of mounting hole axis.
As further improving and supplementing to above-mentioned technical proposal, the utility model further includes that following supplementary technology is special
Sign.
The both ends of the mounting hole are equipped with stepped counterbore.The both ends of bolt can be made to be located in counterbore, make injection molding
The planarization of the both ends of the surface of part is preferable.
The outer peripheral surface of adapter sleeve is equipped with anti-rotation structure.After injection molding part integrated through injection molding, anti-rotation structure be molded into
Type part is stung mutually tightly, can effectively prevent rotating.
Adapter sleeve, which is equipped with, prevents vertical play structure.By preventing vertical play structure, the perpendicular of adapter sleeve can be effectively prevented
It is mobile to stress.
The anti-rotation structure is ridge design.Ridge design increases bite force, prevents from rotating.
The ridge design is annular knurl.The anti-rotation structure is knurling structure.Knurling structure uses universal, processing
Technology maturation simply considerably increases surface occlusion degree, can effective rotation stop in conjunction with injection molding part.
The anti-vertical play structure is the turnup structure at adapter sleeve both ends.Structure is simple, easily manufactured, and is molded into
Type part combines, and can effectively prevent vertically movable.
The turnup structure is outward flanging structure.
The counterbore section is that round, rectangle or ellipse, the cross sectional shape of both ends counterbore are identical or different.Three kinds heavy
Hole shape is simple, easy to process.
The periphery of core body sets that there are four circumferential evenly arranged adapter sleeves.The fastening to stator can be effectively realized,
Axis is parallel, the consistency of direction of vibration, good balance effect when can effectively promote motor operation.
The utility model has the advantages that by the way that mounting hole is set on adapter sleeve, then pass through injection molding part and core body integrated through injection molding,
The structural strength at injection moulded stator mounting hole is improved, after motor long-play, can effectively ensure that mounting hole endface
Flatness and mounting hole axis verticality.

Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Figure of description.
As shown in Figs. 1-2, with the injection moulded stator of adapter sleeve, comprising:
Core body 1；
Adapter sleeve 2, set on the outside of core body 1, adapter sleeve 2 opens up the mounting hole parallel with 1 axis of core body；
Core body 1 and adapter sleeve 2 are rolled into an entirety by injection molding part 3.
In order to make the both ends for installing bolt, evagination, the both ends of mounting hole are not equipped with stepped counterbore 21.It can make the two of bolt
End is located in counterbore 21, and the both ends of bolt not evagination keeps the planarization of the both ends of the surface of injection molding part 3 preferable.
In order to effectively prevent rotating, the outer peripheral surface of adapter sleeve 2 is equipped with anti-rotation structure 22.3 integrated through injection molding of injection molding part
Afterwards, anti-rotation structure 22 and injection molding part 3 are stung mutually tight, can effectively prevent rotating.
Vertical play in order to prevent, adapter sleeve 2, which is equipped with, prevents vertical play structure.It, can be with by preventing vertical play structure
It effectively prevent the vertical applied force of adapter sleeve 2 mobile.
In order to simplify structure, anti-rotation structure 22 is knurling structure.Knurling structure uses universal, processing technology maturation, letter
It is single, surface occlusion degree is considerably increased, is combined with injection molding part 3, it can effective rotation stop.
For the ease of processing, prevent that vertical play structure is the outward flanging structure at 2 both ends of adapter sleeve.Structure is simple, processing
It is convenient, it is combined, can effectively prevent vertically movable with injection molding part 3.
