Abstract
Provided is a motor stator core composite structure, relating to a motor structure and comprising silicon steel sheets punched with a plurality of radial direction line embedding grooves; a plurality of silicon steel sheets are superposed to form a composite structure. The characteristics are that the periphery of the radial direction line embedding grooves of each silicon steel sheet is uniformly punched with six hollow flat cut rectangular pyramid-shaped bosses; the heights of the bosses projecting the silicon steel sheets are equal to or less than the thickness of the silicon steel sheets; when a plurality of silicon steel sheets are superposed, the outside profile of a last boss is sleeved into a cavity of a next boss for close fit, connection and fixing. The advantages are that automatic blanking and stacking in a same direction can be performed for the punching of the silicon steel sheets; when a required number is obtained, the silicon steel sheets are removed and are compacted by press to automatically stitch and connect to form an iron core; the work efficiency is high.
Description
Technical field:
The utility model relates to electric machine structure, particularly a kind of motor stator core combining structure.
Background technology:
Motor stator core is fixedly formed by the some superimposed backs of the silicon steel sheet that is stamped to form, and formed radially line embedding groove coils and then becomes motor stator.Existing stator core is two kinds of fixed forms of general employing in superimposed back: a kind of is to be drilled with six Kong Bingyong bolt penetration hole on the silicon steel sheet to fix; Another kind is that the punching out of silicon steel sheet cylindrical has dovetail groove, and using the cross section is that the urgent matching and fixing of swallow-tailed bracket forms.All want lamination during this dual mode combination, pressing then row again is fixing, and operation is many and work efficiency is low.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and a kind of motor stator core combining structure is provided.
The scheme of the utility model is: comprise silicon steel sheet; Several line embedding grooves radially of punching out on the silicon steel sheet; Some silicon steel sheets are built up combining structure, it is characterized in that: every silicon steel sheet radially line embedding groove periphery also is uniformly distributed with the boss of empty truncate rectangular pyramid shape in six of the punching out, and the height of boss protrusion silicon steel sheet is equal to or less than silicon steel sheet thickness; When some silicon steel sheets were superimposed, last a slice boss gabarit was inserted in down and is tight fit in the cavity of a slice boss and connects fixing.
The advantage of the utility model is: can stack with the orientation blanking automatically during the silicon steel sheet punching out, when waiting to reach quantitative requirement, take out with the forcing press compacting again, auto-stitching is connected to form iron core, and work efficiency is high.

Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
Embodiment:
The utility model comprises silicon steel sheet 1; Several line embedding grooves radially of punching out on the silicon steel sheet 1; Some silicon steel sheets 1 are built up combining structure, it is characterized in that: every silicon steel sheet 1 radially line embedding groove periphery also is uniformly distributed with the boss 2 of empty truncate rectangular pyramid shape in six of the punching out, and the height of boss 2 protrusion silicon steel sheets 1 is equal to or less than silicon steel sheet 1 thickness; When some silicon steel sheets 1 were superimposed, last a slice boss 2 gabarits were inserted in down and are tight fit in the cavity of a slice boss 2 and connect fixing.
