Detailed description of the invention
It should be noted that, the manufacture method of lamination type electric core body of the present invention, lamination type electric core body and the structure of motor, feature and advantage etc. will be illustrated by way of example below, but all of description is intended merely to and illustrates, and should not be construed as and the present invention is formed any restriction.In addition, any single technical characteristic being described by or implying in mentioned each embodiment herein, or shown or implicit any single technical characteristic in the drawings, still can proceed combination in any between these technical characteristics (or its equivalent) or delete, thus acquisition is likely to other embodiments more of the present invention directly not mentioned in this article.It addition, in order to simplify for the purpose of drawing, same or like technical characteristic is likely to only indicate at a place in the same figure.
Incorporated by reference to reference Fig. 1, Fig. 2 and Fig. 3, by these accompanying drawings only illustrate the basic structure according to the lamination type electric core body embodiment of the present invention and manufacture method in a schematic way thereof.
As shown in the figures above, in this lamination type electric core body embodiment provided, initially with the such as technology mode such as riveting, punching press, multiple motor core body monolithics 2 are laid out lamination treatment, thus being compressed and the lamination type electric core body 1 of forming as one by these motor core body monolithics 2, and on this lamination type electric core body 1, define lamination portion 5 simultaneously.
It should be noted that, for having been carried out the lamination type electric core body 1 after stacked lamination treatment, adhesion between wherein compacted each motor core body monolithic 2 is likely to or insufficient, it is possible to influence whether performance and the quality of lamination type electric core body.
For example, such as, in shown in FIG chute type motor core body, owing to the groove 4 between the pole body 3 circumferentially distributed along motor core body and these pole bodies 3 is configured to constitute angle of inclination relative to the axis of this motor core body, therefore when by Exciting Windings for Transverse Differential Protection in time being located on these pole bodies 3, Exciting Windings for Transverse Differential Protection will apply tensile force to it, thus may result in the inclination angle of these pole bodies 3 and deviate its desired value, and their angle deviating degree is likely to be inconsistent on the whole, thus being unfavorable for ensureing the stability of motor, it could even be possible to cause that worsening occur in performance indications, the serious reliability damaging motor and safety.
For this, in the manufacture method of lamination type electric core body provided by the present invention, except, except motor core body monolithic 2 is laid out lamination treatment, the inventive method also add other multiple steps such that it is able to be obviously enhanced the adhesion between these motor core body monolithics 2 further.
Specifically, it is being stacked on the lamination type electric core body 1 after lamination compresses, first axially offer one or more hole 6 along this lamination type electric core body 1, this lamination type electric core body 1 is carried out gluing process process will pass through hole 6, the various somes glue modes such as such as manual spot-gluing, manual glue rifle point glue, semi-automatic or full-automatic point gum machine point glue namely can be adopted to be filled in lamination type electric core body 1 via hole 6 by adhesive.Then, along with adhesive is in the flowing within lamination type electric core body 1, infiltration, these adhesives will be poured and be adequately attached on motor core body monolithic 2 each contact surface to each other.Subsequently, just the lamination type electric core body 1 after having filled in adhesive can be placed, to wait that adhesive forms powerful adhesion after solidifying, thus just can combine more solid and reliable for each motor core body monolithic 2 in lamination type electric core body 1, so that the overall structure of lamination type electric core body 1 more fastens and can keep preset shape for a long time, so even be also be less likely to occur deformation when bearing bigger External Force Acting.
For the above-mentioned hole 6 being arranged on lamination type electric core body 1, as exhibited in Fig. 1 and Fig. 2, it is possible to this some holes 6 is opened in respectively and is formed in the lamination portion 5 on lamination type electric core body 1 via the lamination treatment such as riveting or punching press.Under different application scenarios, such lamination portion 5 can be configured to strip, circle, ellipse or any other suitable shape.When hole 6 being arranged in these existing lamination portions 5, such as they are arranged on the one end in lamination portion 5, middle part or other appropriate site, not only can minimize the overall appearance of lamination type electric core body 1 is affected, and due in lamination portion 5 usually lamination type electric core body 1 compacted combination obtain the most firmly position, therefore offer hole 6 over these locations partly and contribute to keep originally compressing in conjunction with effect between stack chip motor core body monolithic 2.
Certainly, also should it is to be noted, according to concrete conditions of demand, on other positions allowing completely to flexibly be located on lamination type electric core body 1 by hole 6 in the manufacture method of the lamination type electric core body of the present invention, and it is not limited solely to be arranged in above-mentioned lamination portion 5.Additionally, in alternative circumstances, it may be considered that only the part in this some holes 6 is arranged on lamination portion 5, and another part therein is arranged on other positions on lamination type electric core body 1.
Additionally, it is understandable that, in the manufacture method of the lamination type electric core body of the present invention, it is possible to the circumference that hole 6 is arranged along lamination type electric core body 1 alternatively is evenly arranged, and/or the circumference that lamination portion 5 is arranged along lamination type electric core body 1 is evenly arranged.Certainly, other any suitable location needed according to application and be separately positioned on lamination type electric core body 1 by above-mentioned hole 6, lamination portion 5 are also allowed to.
As an example, schematically illustrate an end face of this lamination type electric core body embodiment in fig. 2, by showing can be arranged in hole 6 in this embodiment through hole or blind hole (namely in conjunction with Fig. 1, blind hole is to seal on one layer of this lamination type electric core body bottommost or some layers of monolithic), this is based on is easy to the on-demand consideration carrying out the aspects such as hole machined.If hole 6 is arranged to through hole, then when implementing gluing process and processing, the bottom of a part of hole in this some holes 6 on the same end face of this lamination type electric core body 1 or all well can also be will be located in alternatively block, in order to the adhesive contributing to filling in can flowing and infiltration better inside lamination type electric core body 1.
It addition, in alternative circumstances, the manufacture method of the lamination type electric core body of the present invention allows only the part in hole 6 to be selectively set to through hole.And, for whole holes 6, the parameters such as the degree of depth of each of which, aperture can also need freely according to application, flexibly set, so as to promote those monolithics of each monolithic in lamination type electric core body or key area can more fasten, more combine muchly.
Again as shown in Figure 3, when the manufacture method at the lamination type electric core body of the present invention being implemented gluing process and processing, spot gluing equipment 8 can be used and nozzle 7 is inserted in the hole 6 of lamination type electric core body 1, thus adhesive being filled into the inside of lamination type electric core body 1, the point glue amount of filling in of adhesive can be may be alternatively arranged as 0.005-0.02 Grams Per Second, or can also according to the actual size of lamination type electric core body 1, the actual size in hole 6, the material property that lamination type electric core body monolithic 2 adopts, it is adjusted by the concrete conditions such as the model of adhesive flexibly.
As an example, spot gluing equipment 8 can select automation equipment or Semi-automatic device, thus can drip under the Parameter Conditions such as time at the operating air pressure preset, note, guarantee to be filled in each hole 6 identical glued dosage, thus contributing to ensureing on the whole that the adhesion everywhere of lamination type electric core body 1 keeps uniformity.
Again for example, there is PROCESS FOR TREATMENT simply, flexibly owing to putting glue mode manually, and the feature such as with low cost, therefore under some application scenarios, can also adopt in the manufacture method of the lamination type electric core body of the present invention manually some glue mode to carry out gluing process process.
Technique is processed owing to the manufacture method at the lamination type electric core body of the present invention employing a glue, its have flexible operation, range of application widely, process the advantages such as surface combination is firm and smooth, therefore obtained after adhesive solidifies lamination type electric core body finished product not only smooth in appearance, and internal bond strength is enhanced considerably, after a glue processes, the internal bond strength of lamination type electric core body can be strengthened at least 1 times more than according to test surfaces.So, even if by Exciting Windings for Transverse Differential Protection in time being located on this lamination type electric core body, the tensile force that Exciting Windings for Transverse Differential Protection applies also is not enough to change original position and the form in each portion in this lamination type electric core body, because of without causing motor performance and quality that less desirable change occurs.
In the manufacture method of lamination type electric core body provided by the present invention, when filling in after the adhesive within lamination type electric core body 1 is complete solidification, can further by Exciting Windings for Transverse Differential Protection on the pole body being located at this lamination type electric core body, thus forming stator suitable in all kinds of motor products.
Although it should be noted that be exemplified as lamination type electric core body there is flume structure in the above-described embodiments, but in the lamination type electric core body that manufacturing method according to the invention provides, it is possible to be set to and there is straight groove structure.
In addition, it can further be stated that, in the lamination type electric core body that manufacturing method according to the invention provides, quantity, position etc. are specifically set all can the carrying out setting flexibly according to practical application of pole body and the groove between these pole bodies.Additionally, in the lamination type electric core body that manufacturing method according to the invention provides, monolithic quantity, shape, size etc. also all can select to set, and can there are differences in outer shape, gauge etc. between the different monolithics in same lamination type electric core body.
Based on lamination type electric core body provided by the present invention, it is possible to be attached in various types of motor product (being used for example as motor stator or rotor).Thus, as previously mentioned, can not only be effectively ensured it according to motor product provided by the present invention and possess acceptable performance and reliable quality when being dispatched from the factory by manufacture completely, and contribute to promoting these motor products can stable operation chronically, thus improving security performance and extending service life.
Below the manufacture method of lamination type electric core body of the present invention, lamination type electric core body and motor are only elaborated by way of example, these a few examples are intended for illustrating the use of principles of the invention and embodiment, but not limitation of the present invention, without departing from the spirit and scope of the present invention, those skilled in the art can also make various deformation and improvement.Therefore, all equivalent technical schemes all should belong to scope of the invention and the every claim by the present invention is limited.
