Abstract
A kind of split-type core structure of rivet interlacement, including segmental core unit, iron core base, its spy is characterized in that the right and left of each segmental core unit is provided with rivet hole, there is rivet insertion in the rivet hole of segmental core unit, the front and back two sides for the adjacent segmental core unit that lower end side is closely packed together is respectively arranged with connection sheet, and the both ends of the rivet on adjacent segmental core unit are riveted on respectively in the connection sheet on the front and back two sides of adjacent segmental core unit.The present invention is compared with the prior art.With easy to assembly, split-type stator core is able to achieve after assembly again and is connected with each other fastening sufficiently, it avoids the occurrence of motor and the problems such as unreliable work, fluctuation of service, big noise occurs due to dividing the axial dimension of valve iron core to misplace, while reducing motor manufacturing cost, and the advantages of improve the performance of motor.
Description
Technical field
The present invention relates to motor technologies.
Background technique
With the continuous promotion of manufacturing technology, motor manufacturing technology is also being constantly progressive with motor process technology.People couple
The requirements such as motor volume, weight, performance, service life are also higher and higher.Split-type stator core makes mould because its motor copper factor is high
Has size small, stock utilization is high, the low advantage of input cost, and many electrical machinery plants of attraction slowly developed implementation, example in recent years
Such as technology disclosed in Chinese patent CN201710517833, by between the segmental core unit interference inlay wedge, realize point
Flap-type stator core is connected with each other the purpose of fastening.
Above-mentioned technology the problem is that: since sector element is connected using wedge, by being extruded in adjacent sector
Realize that Tenon is close between iron core unit, but the joinery and its construction between segmental core unit does not have axial restraint, and it is uneven to be easy connection
It weighs, fasten insufficient and be easy to have dislocation in motor axial direction dimensional directions, generate motor because of uneven in operation
Noise, vibration, therefore a kind of connection structure method of split-type inner-stator iron core of patent CN201710517833 introduction, but simultaneously
Operational reliability present on structure is not solved the problems, such as.
Summary of the invention
The object of the present invention is to provide a kind of easy to assembly, be able to achieve again after assembly split-type stator core be connected with each other it is tight
There is unreliable work, fluctuation of service, noise due to dividing the axial dimension of valve iron core to misplace Gu sufficiently, avoiding the occurrence of motor
The problems such as big, while reducing motor manufacturing cost, and improves the split-type iron core knot of the rivet interlacement of the performance of motor
Structure.
The present invention is implemented as follows: including segmental core unit, iron core base, the top of segmental core unit two sides is set
It is equipped with groove, groove is used for around stator coil, its special feature is that the right and left of each segmental core unit is provided with
Rivet hole has rivet insertion, the adjacent segmental core unit that lower end side is closely packed together in the rivet hole of segmental core unit
Front and back two sides be respectively arranged with connection sheet, the both ends of the rivet on adjacent segmental core unit are riveted on adjacent fan-shaped iron respectively
In the connection sheet on the front and back two sides of core unit, flush the above and below of adjacent segmental core unit, a number of sector
Iron core unit combination just forms circular stator core, and iron core base interference is inlayed into the circular stator core inner hole after combination
It is interior.
Beneficial effect
1, split-type stator core is connected with each other fastening sufficiently by rivet and connection sheet, and iron core unit both will not circumferencial direction shifting
It is dynamic that axile displacement, stable and reliable operation be not high yet；
2, fan-shaped stator core unit can be separated from stator core, both facilitate coiling, improved motor copper factor, in turn, ensured that
Distribution of Magnetic Field is uniform；
3, production die size can be reduced by being divided into several fan-shaped stator core units, reduce Mold Making cost；
4, stock utilization can be improved, reduce motor manufacturing cost.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is adjacent segmental core unit catenation principle figure.
Specific embodiment
Now in conjunction with drawings and examples, present invention is further described in detail:
As shown, the present invention includes segmental core unit 1, iron core base 4, the top of 1 two sides of segmental core unit is provided with
Groove 1a, groove 1a are used for around stator coil, its special feature is that the right and left of each segmental core unit 1 is provided with
There are the insertion of rivet 2, the adjacent sector that lower end side 1c is closely packed together in rivet hole 1b, the rivet hole 1b of segmental core unit 1
The front and back two sides of iron core unit 1 is respectively arranged with connection sheet 3, and the both ends of the rivet 2 on adjacent segmental core unit 1 rivet respectively
Before and after the adjacent segmental core unit 1 in the connection sheet 3 on two sides, flush the above and below of adjacent segmental core unit 1,
The a number of combination of segmental core unit 1 just forms circular stator core 5, and 4 interference of iron core base is inlayed into after combination
In circular 5 inner hole of stator core.
