Background technology
Stator core manufacture method in motor is all generally to press together with punching and cramp, and the stator cores that use straight channel type to press-fit in prior art more, the mould using in traditional manufacturing process is to use screw mandrel to be rotated down mostly, make mode that expansion core presses down with screw mandrel promote expansion block and outwards push iron core, owing to adopting the mode of manpower extruding expansion core, make expansion block can not have enough strength extruding iron cores, can not effectively realize the object of smooth iron core inner headed face.Can not rationally be controlled because iron core in extrusion process is stressed, iron core is easily produced and be out of shape the phenomenons such as loosening simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of expanding type motor stator core press mounting die that is applied to power domain, can effectively overcome above-mentioned defect, when effectively realizing stator core inner cylinder face smooth, can effectively prevent the stress deformation of iron core, and realize the mechanized operation of smooth stator core.
The utility model is achieved through the following technical solutions: a kind of expanding type motor stator core press mounting die that is applied to power domain, mainly formed by base, expansion block, expansion core, interior bar, described interior bar bottom is fixed on base center, described expansion core is sleeved on interior bar, described expansion block is sleeved on expansion core outside, stator core to be press-fited is sleeved on expansion core outside, is also fixed with cramp above described base, and described cramp internal diameter is greater than stator core external diameter.
Further, for realizing better the utility model, between described expansion block bottom and base, flexible rubber circle is installed.
Further, for realizing better the utility model, be set with successively from bottom to top pressing plate, spring, sleeve pipe on bar in above described expansion core.
Further, for realizing better the utility model, be provided with through hole on described interior bar top.
Further, for realizing better the utility model, below described expansion core, packing ring is installed.
Further, for realizing better the utility model, be set with supporting seat on bar in below described expansion core.
The utility model compared with prior art, has following beneficial effect:
(1) the utility model can be realized the object of smooth stator core inner cylinder face, and by optimal design, can overcome the unbalance stress defect of original hand-guided, realizes the mechanization operation to operating process;
(2) the utility model is by structures such as design pressing plate, spring, sleeve pipes, can, realizing during iron core inner cylinder face is press-fited to process the object that avoid distortion, prevent core slackness, effectively ensure the quality of iron core.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment 1:
As shown in Figure 1, a kind of expanding type motor stator core press mounting die that is applied to power domain, mainly formed by base 1, expansion block 3, expansion core 4, interior bar 5, described interior bar 5 bottoms are fixed on base 1 center, described expansion core 4 is sleeved on interior bar 5, and described expansion block 3 is sleeved on expansion core 4 outsides, and stator core 6 to be press-fited is sleeved on expansion core 4 outsides, above described base 1, be also fixed with cramp 2, described cramp 2 internal diameters are greater than stator core 6 external diameters.For realizing better the utility model, between described expansion block 3 bottoms and base 1, flexible rubber circle 7 is installed.In use, stator core 6 is put into cramp 2 inside, can promote expansion core 4 expansion block 3 is outwards pushed by rotating interior bar 5, thereby realize smooth stator core 6 inner headed faces.
Embodiment 2:
As shown in Figure 2, on the basis of embodiment 1, for realizing better the utility model, be set with successively from bottom to top pressing plate 8, spring 9, sleeve pipe 10 on bar 5 in above described expansion core 4.For realizing better the utility model, in described sleeve pipe 10 tops, on bar 5, be provided with through hole 11.By pressing plate 8, spring 9 and sleeve pipe 10 are set, hydraulic mechanism can be fixed on through hole 11, thereby realize inner-stator iron core 6 inner cylinder faces smooth time, prevent stator core distortion, loosening, effectively ensure the quality of stator core 6.Other parts of the present embodiment are identical with embodiment 1, repeat no more.
