Abstract
A large-sized motor stator lamination prepressing tooling comprises a lower prepressing plate (a reference plate) and an upper prepressing plate. The lower prepressing plate is mounted on a mechanical jack and leveled by an adjusting nut on the mechanical jack, the mechanical jack is placed on a bottom surface via a support, a screw rod mounting hole is arranged on the lower prepressing plate(the reference plate), a screw rod inserted into the screw rod mounting hole is a double-ended screw rod, one end of the screw rod penetrates through the lower prepressing plate and is jammed by a nut, the other end of the screw rod penetrates through the upper prepressing plate to extend out of the upper prepressing plate, a threaded portion is arranged on the part, extending out of the upper prepressing plate, of the screw rod, a compression nut is sleeved on the threaded portion, extending out of the upper prepressing plate, of the screw rod, and a stator chip is pressed between the upper prepressing plate and the lower prepressing plate. The large-sized motor stator lamination prepressing tooling has the advantage that the tooling omits suspending an iron core during lamination, prevents iron core reference from loosening, performs lamination and pressing at the same platform position, requires no large-sized oil press, and is flat in the iron core, fine in integrity and stable in lamination coefficient.
Description
Technical field
The utility model relates to a kind of motor component processing and fabricating frock, is a kind of large-size machine stator lasmination Prepressing working specifically, and this large-scale integral lamination Prepressing working mainly is applicable to the making of large-scale iron core.
Background technology
Motor mainly is made up of stator and rotor two parts, and wherein stator core is the vitals of stator, all is that stator core laminates the magnetic conduction efficient that quality directly has influence on stator core by the silicon steel plate stacking moulding of permeability magnetic material.In order to guarantee that laminating of stator core meets the requirements, generally all be to laminate frock by a stator core to laminate stator core now.But because the large-size machine stator core is very huge, general stator core now laminates frock and can not meet the demands; Such as the production that laminates for the large-size stator iron core of diameter more than 4 meters, have and do not wish to hang iron core in the lamination process, avoid benchmark unshakable in one's determination loosening, existing stator core laminates frock and does not just accomplish this point; So need a kind of energy newly developed to be suitable for the frock that laminates of high-power half direct-drive permanent magnet wind power generator stator core.
Summary of the invention
The purpose of this utility model exactly in order to overcome the deficiency of existing large-size machine stator core, proposes a kind ofly can adapt to the frock that the large-size machine stator core laminates moulding; This frock electric machine stator iron lamination press-fits and is in same position, need not hang unshakable in one's determinationly in the lamination process, need not dispose large-sized hydraulic press, and unshakable in one's determination smooth, globality is good.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of large-size machine stator core laminates the frock of moulding, comprises a following prefabricating plate (datum plate), goes up prefabricating plate for one.Following prefabricating plate is installed on the mechanical type jack, and by the adjusting nut leveling on the mechanical type jack, the mechanical type jack is placed on the bottom surface by bearing; Having the screw rod installing hole on the prefabricating plate (datum plate) down, be inserted with screw rod in the screw rod installing hole, screw rod is a double threaded screw, one is passed down prefabricating plate.By nut and tight, prefabricating plate is then passed in the screw rod other end, reaches outside the prefabricating plate, and prefabricating plate partly for threaded portion, is with clamp nut on the threaded portion on screw rod reaches outside the prefabricating plate on reaching; Stator chip is pressed between prefabricating plate and the following prefabricating plate; In order to guarantee installation accuracy, on last prefabricating plate and following prefabricating plate, also be provided with location hole, be inserted with alignment pin in the location hole.The suspension ring that are used to sling also are installed on last prefabricating plate.
The utility model has and need not hang iron core in the lamination process for the production that laminates of the large-size stator iron core of diameter more than 4 meters, avoids benchmark unshakable in one's determination loosening, lamination press-fits and is in same position, need not dispose large-sized hydraulic press, and is unshakable in one's determination smooth, globality is good, the advantage that stacking factor is stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, go up prefabricating plate; 2, following prefabricating plate; 3, mechanical type jack; 4, adjusting nut; 5, bearing; 6, screw rod installing hole; 7, screw rod; 8, nut; 9, threaded portion; 10, clamp nut; 11, stator chip; 12, location hole; 13, alignment pin; 14, suspension ring.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the utility model is the frock that a kind of large-size machine stator core laminates moulding, comprises 1, one last prefabricating plate 2 of a following prefabricating plate (datum plate).Following prefabricating plate 1 is installed on the mechanical type jack 3, and by 4 leveling of the adjusting nut on the mechanical type jack 3, mechanical type jack 3 is placed on the bottom surface by bearing 5; Having screw rod installing hole 6 on the prefabricating plate (datum plate) 1 down, be inserted with screw rod 7 in the screw rod installing hole 6, screw rod 7 is a double threaded screw, 7 one of screw rods pass down prefabricating plate 1.By nut 8 and tight, prefabricating plate 2 is then passed in screw rod 7 other ends, reaches outside the prefabricating plate 2, and prefabricating plate partly for threaded portion 9, is with clamp nut 10 on the threaded portion 9 outside screw rod 7 reaches prefabricating plate on reaching; Stator chip 11 is pressed between prefabricating plate 1 and the following prefabricating plate 2; In order to guarantee installation accuracy, on last prefabricating plate 1 and following prefabricating plate 2, also be provided with location hole 12, be inserted with alignment pin 13 in the location hole 12.The suspension ring 14 that are used to sling also are installed on last prefabricating plate.
After the mechanical type jack leveling of following prefabricating plate by configuration, guarantee concordantly, make that fanning strip has had positioning reference in the lamination with the support lower surface.Datum plate thickness is suitable simultaneously, and material is Q235A, when guaranteeing enough intensity, has suitable toughness, and this toughness can realize down the leveling of prefabricating plate and support lower surface.
Last prefabricating plate is used with following prefabricating plate, and inside and outside two circle fastening screws are arranged on the plate, can prevent the song of lifting up of punching and prefabricating plate when tightening.Carry out precompressed by this structure, reach the quality of the whole precompressed iron-core lamination of large-sized hydraulic press fully.After press-fiting, weld by this structure, tightness unshakable in one's determination and stacking factor have been guaranteed.
