Abstract
The utility model discloses a top positioning assembly including an expansion core (1) having a perpendicular narrow opening. More than two vertical ridges are arranged in the outer periphery of the expansion core (1). The inner diameter of the expansion core is big end down and the expansion core is provided with a corresponding top cone. A spring (4) is arranged below the top cone (3). A top hydraulic cylinder (5) is arranged below the spring (4). The top positioning assembly in the utility model is used for precise positioning of sheets of two stator iron cores and the sheets are not easy to misplace.
Description
Technical field
The utility model relates to a kind of top positioning component, particularly a kind of last top positioning component that is used for the stator core preforming device gone up.
Background technology
Stator core in the motor is with the formation that is superimposed of blocks of silicon steel sheet; In manufacture process; Because the silicon steel sheet difference that the punching out silicon steel sheet is used; Can occur the thin phenomenon in thick one side on one side after the silicon steel sheet that punching out goes out is superimposed, cause the unbalanced of stator core, influence the electric property of motor.In order to guarantee the harmony of stator core, when producing, the silicon steel sheet that constitutes stator core is divided into two groups is pressed into two stator blocks (stator lamination), in two stator blocks one of them horizontally rotated 180 degree after, linking together then.So just can guarantee the harmony of the stator core size of whole motor.Usually two stator blocks are linked together and realize, and during punching press, the location of two stator laminations is very important, because stator lamination directly causes the birth of waste product slightly once misplacing through punching press.
The utility model content
The purpose of the utility model is, a kind of top positioning component of going up is provided.It can realize the accurate location to the sheet of two stator cores, is difficult for producing dislocation.
The technical scheme of the utility model: a kind of top positioning component of going up; Be characterized in: comprise the bloated core of vertically offering slot; Bloated core periphery is provided with the ridge of the vertical direction more than two, and bloated in-core is directly big down little, and bloated in-core is provided with corresponding addendum cone; Addendum cone has spring, and spring has the top hydraulic cylinder.
In the above-mentioned last top positioning component, the bottom of its said bloated core is provided with catch.
Compared with prior art; The utility model is through offering the bloated core of slot; At bloated in-core addendum cone is set, the core of can realizing expanding when on addendum cone, pushing up rises and opens this two processes, can carry out synchronized positioning with the stator lamination chucking and through the ridge that snaps in the lamination wire casing.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Being labeled as in the accompanying drawing: the 1-core that expands, 2-ridge, 3-addendum cone, 4-spring, the last top of 5-hydraulic cylinder, 6-catch.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of top positioning component of going up, as depicted in figs. 1 and 2, comprise the bloated core 1 of vertically offering slot; Bloated core 1 periphery is provided with the ridge 2 of the vertical direction more than two, and core 1 internal diameter that expands is big down little, and is provided with corresponding addendum cone 3 in the bloated core 1; Addendum cone 3 has spring 4, and spring 4 has top hydraulic cylinder 5.The bottom of said bloated core 1 is provided with catch 6.
Operation principle: on station, by the last top hydraulic cylinder of last top positioning component 5 jack-up upwards, because the effect of spring 4; Addendum cone 3 ejects workbench with whole bloated core 1, inserts stator lamination, on push up to a certain degree after; The catch 6 of core 1 bottom has propped up workbench owing to expand, and addendum cone 3 relative expanding cores 1 are subjected to displacement, because core 1 internal diameter that expands is up-small and down-big; The core 1 that expands will expand outwardly under the effect of addendum cone 3; Thereby block the stator lamination internal diameter, and the outer ridge 2 of bloated core 1 can snap in the wire casing of stator lamination just, thereby can prevent the dislocation of two stator laminations.
Claims (2)
1. go up the top positioning component for one kind; It is characterized in that: comprise the bloated core (1) of vertically offering slot; Bloated core (1) periphery is provided with the ridge (2) of the vertical direction more than two, and core (1) internal diameter that expands is big down little, and is provided with corresponding addendum cone (3) in the bloated core (1); Addendum cone (3) has spring (4), and spring (4) has top hydraulic cylinder (5).
2. the top positioning component of going up according to claim 1, it is characterized in that: the bottom of said bloated core (1) is provided with catch (6).
