Abstract
The utility model relates to motors and discloses a riveting iron core of a miniature vibration motor. The iron core is formed by laminating a plurality of punching sheets in riveting mode, shaft holes are punched at the center of the punching sheets, a plurality of wire groove sheets which are wound windings in embedded mode and distributed evenly are punched on the periphery of the punching sheets, and a plurality of riveting holes are punched on the wire groove sheets. The riveting iron core of the miniature vibration motor has the advantages of reducing production cost.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of riveted joint iron core of micro-vibration motor.
Background technology
The micro-vibration motor is meant that mainly products such as being used for mobile phone drives the address of the micromachine of vibrating member.The micro-vibration motor is made up of stator and rotor usually; Stator constitutes permanent magnet poles by magnet steel; Rotor produces electromagnetic pole so that winding energising back to be installed on the iron core, and core center is provided with the mesopore of a fixed installation armature spindle, under the effect of electromagnetic pole and permanent magnet poles, drives rotor rotation.Iron core in the existing rotor is to utilize laser welding to form by magnetic conductor punching (also can be called chip) phase poststack, and the cost cost of this iron core is higher.
Summary of the invention
To above-mentioned deficiency, the utility model is exactly the riveted joint iron core that a kind of processing cost micro-vibration motor that low iron core constitutes will be provided.
The utility model is realized through following technical measures; A kind of riveted joint iron core of micro-vibration motor; Said iron core is to be formed by stacking by multi-disc punching riveted joint; The centre punch of said punching is pressed with axis hole, is stamped into the wire casing sheet of equally distributed a plurality of embedding around winding around the said punching, and punching press has a plurality of riveted holes on this wire casing sheet.
Concrete, peripheral equally distributed three the wire casing sheets that are stamped into of said punching.
As a kind of optimal way, the corner of the wire casing sheet of two punchings of said outermost end is fillet.
The riveted joint iron core of the micro-vibration motor that the utility model provides because punching press has a plurality of riveted holes on the wire casing sheet of the punching of forming iron core, makes between the punching and builds up iron core mutually through riveted joint, and then has reduced the production cost of producing iron core.Promptly compared with prior art, the cost of the utility model is lower, thereby makes product more competitive on market.
The riveted joint iron core of the micro-vibration motor that the utility model provides, the outside of two punching wire casing sheets of outermost end is fillet.Punching is with stamping forming; Punching is for be the punching press fillet on one side after the punching press, and another side is the punching press burr, and the prior art iron core just winds the line the same direction phase of punching poststack; So danger that the punching press burr is scraped broken string when having coiling; The utility model all becomes fillet with the iron core two ends, i.e. the face outwardly of outermost two punchings of iron core all is fillet on wire casing.Be difficult for broken string when therefore the utility model can reach coiling, improved the production qualification rate greatly, and the effect of motor properties stability and reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model punching.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further elaborated.
A kind of riveted joint iron core of micro-vibration motor; Be formed by stacking by multi-disc punching 1 riveted joint; The centre punch of punching 1 is pressed with axis hole 103, be stamped into around the said punching 1 equally distributed three embeddings on 101, three wire casing sheets 101 of wire casing sheet of winding all punching press riveted holes 102 is arranged; Iron core is to be formed by stacking by multi-disc punching 1 riveted joint, and wherein the outside of the wire casing sheet 101 of two punchings of outermost end is fillet.
More than be that the riveted joint iron core of the utility model micro-vibration motor is set forth; Be used for helping to understand the utility model; But the execution mode of the utility model is not restricted to the described embodiments; Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection range of the utility model.
Claims (3)
