Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of structure for press-fiting swollen tire of electric machine stator iron is improved.
Background technology
The manufacture method of electric machine stator iron is typically all that will stack neat punching to press together with cramp, and motor is fixed
Sub line embedding groove regularity unshakable in one's determination and perpendicularity are very big on the performance of motor and the influence of lower road rule procedures, particularly automatic
Change coil inserting apparatus, the line embedding groove regularity of stator core with perpendicularity is unqualified will be unable to normally use, traditional motor stator iron
The heart be fitted in punching it is swollen it is neat after, groove lining bar need to be tapped with iron hammer by electric machine stator iron correcting, low production efficiency, stability is poor,
Quality is difficult to ensure that motor production cost is high.
The content of the invention
Press-fit swollen tire it is an object of the invention to provide a kind of electric machine stator iron, being capable of correcting while swelling pressure is unshakable in one's determination
Groove profile unshakable in one's determination.
To achieve these goals, the technical solution adopted by the present invention is：A kind of electric machine stator iron press-fits swollen tire, bag
Expansion core and the expansion set being set in outside expansion core are included, waits that press-fiting A unshakable in one's determination is sleeved on outside expansion set, with iron to be press-fited on the outer wall of expansion set
The locating slot corresponding position of the heart is provided with guide and limit muscle.
In such scheme, wait press-fit it is unshakable in one's determination prepare to be enclosed on expansion set periphery when, wait to press-fit the locating slot and guide and limit of iron core
Muscle aligns, the proper alignment unshakable in one's determination when the guide and limit of guide and limit muscle acts on expansion set tensioner one by one, it is ensured that iron
The perpendicularity of the heart.
Brief description of the drawings
Fig. 1 is the top view of swollen tire；
Fig. 2 is Fig. 1 C-C sectional views；
Fig. 3 is swollen tire and waits to press-fit the cooperation schematic diagram of iron core；
Fig. 4 is the dimensional structure diagram of expansion set.
Embodiment
Refering to shown in Fig. 1-Fig. 4, a kind of electric machine stator iron press-fits swollen tire, including expansion core 10 and is set in outside expansion core 10
The expansion set 20 in portion, waits that press-fiting A unshakable in one's determination is sleeved on outside expansion set 20, with waiting to press-fit A unshakable in one's determination B pairs of locating slot on the outer wall of expansion set 20
Answer and guide and limit muscle 30 is provided with position.When press-fiting A unshakable in one's determination and preparing to be enclosed on 20 periphery of expansion set, wait to press-fit A unshakable in one's determination positioning
Groove B aligns with guide and limit muscle 30, the iron when guide and limit of guide and limit muscle 30 acts on 20 tensioner of expansion set one by one
Heart proper alignment, it is ensured that perpendicularity unshakable in one's determination.
It is preferred that, described guide and limit muscle 30 is the batten that vertical direction is arranged, the width of batten is with waiting to press-fit A unshakable in one's determination
Locating slot B notches coincide.So wait that the locating slot B for press-fiting A unshakable in one's determination is directed at the upper end of batten, and glided along batten, so
Each locating slot B unshakable in one's determination is all on same straight line, it is ensured that perpendicularity and axiality unshakable in one's determination.
Further, the conical surface shape that expansion set 20 is tapered into from top to bottom for the equal cylinder shape of external diameter, internal diameter, expansion core 10
For tubular, the external diameter of expansion core 10 is the conical surface shape tapered into from top to bottom and coincide in the internal diameter of expansion set 20, the cylinder of expansion core 10
Bottom offers the connecting hole 11 coordinated with interior bar.It will wait that press-fiting A unshakable in one's determination is enclosed on the periphery of expansion set 20 first, because now expansion set 20 does not have
Have swelling, so wait that press-fiting A unshakable in one's determination is easy for setting up, and then inserts expansion core 10 from the upper end of expansion set 20, interior bar with
Connecting hole 11, which is assembled, slowly pulls down expansion core 10 so that expansion set 20 radially gradually swells, the iron core to be press-fited of swelling periphery
A。
In order that expansion set 20 can swell in radial direction, the barrel of expansion set 20 is by upper end to lower end edge cylinder circumference
21 and only one clearance gap 21 for barrel outer wall inward wall insertion are stitched every being provided with 3 interspaces.
Further, remaining two interspace seam 21 for the middle part inward walls extension of barrel wall thickness and the gap of insertion inwall and
In 120 ° of angle distributions between 3 interspaces seam 21.
