Abstract

The utility model discloses a laminated die of a high voltage generator stator core. The laminated die comprises a bottom plate, an upper pressure plate, a central shaft and a pressure ring. The inner circle of the bottom plate is in clearance fit with the outer circle of a lower pressure ring of the stator; the large inner ring of the upper pressure plate is in clearance fit with the outer circle of an upper pressure ring of the stator; the peripheral face of the central shaft is in clearance fit with the inner ring of the stator corer, the small inner circle of the upper pressure plate and a circular groove of the bottom plate; the shape of a locating key on the central shaft is matched with the groove shape of a stator punching; and the pressure ring is arranged on the upper part of the upper pressure plate. According to precise limitation of many parts, the laminated die can meet the technical requirements on concentricity of the stator punching and the stator pressure ring, dimension parameters and laminating coefficients of straightness of the groove shape of the stator core, a flicking degree of groove teeth and the like in the laminating process of the stator core. The laminated die is convenient to use, easy to operate and simple to disassemble, the laminating quality of the stator core with high precision can be ensured, and further, the high quality of a generator is ensured.

Description

The laminated mold of high-voltage generator stator core

Technical field

The utility model relates to mechanism of power generation technology for making field, especially a kind of laminated mold of high-voltage generator stator core.

Background technology

Stator core is the vitals in the generator, is laminated by a lot of sheet stator punchings to form, and its quality that laminates quality has directly affected the quality of generator quality.Stator core laminates the location that at first will consider stator punching in the production, secondly is stator punching and the concentricity of trim ring (because stator pressing ring docks with generator pit), the linearity of stator core flute profile etc.In the existing manufacture process, only stator punching is carried out simply spacingly, therefore be difficult to guarantee the high-precision quality that laminates.

The utility model content

The applicant is for laminating the shortcomings such as quality is on the low side in the above-mentioned existing generator stator core manufacturing, a kind of laminated mold of high-voltage generator stator core rational in infrastructure is provided, thereby guarantees that high-precision stator core laminates quality.

The technical scheme that the utility model adopts is as follows:

A kind of laminated mold of high-voltage generator stator core, comprise base plate, top board, central shaft and pressure ring, the lower clamping ring cylindrical matched in clearance of the inner circle of base plate and stator lower clamping ring, upper trim ring cylindrical matched in clearance on the large inner circle of top board and the stator on the trim ring, the little inner circle of the outer peripheral face of central shaft and stator core inner circle, top board and the cannelure matched in clearance of base plate, positioning key on the central shaft matches with the flute profile of stator punching, is provided with pressure ring on top board top.

The beneficial effects of the utility model are as follows:

The utility model is spacing by the many places precision, guaranteed in the stator core lamination process, the specification requirements such as the linearity equidimension parameter of the concentricity of stator punching and stator pressing ring, stator core flute profile and stacking factor, groove tooth degree of flicking, easy to use, easy operation, dismounting are simply, can guarantee that high-precision stator core laminates quality, and then guarantee high-quality generator product quality.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As shown in Figure 1 to Figure 3, high-voltage generator stator core 5 is comprised of 16 stacks of multi-disc stator punching, is pressed with trim ring 7 on the stator in the upper end, is pressed with stator lower clamping ring 3 in the lower end.Laminated mold described in the utility model is comprised of with pressure ring 15 base plate 1, top board 9, central shaft 12, and the inner circle 2 of base plate 1 and lower clamping ring cylindrical 4 matched in clearance of stator lower clamping ring 3 are as the positioning datum of stator lower clamping ring 3.Upper trim ring cylindrical 8 matched in clearance on the large inner circle 10 of top board 9 and the stator on the trim ring 7 are as the positioning datum of trim ring on the stator 7.The outer peripheral face 13 of central shaft 12 and cannelure 17 matched in clearance of the little inner circle 11 of stator core inner circle 6, top board 9 with base plate 1, radial location benchmark as stator punching 16, simultaneously, match with the flute profile of stator punching 16 with the positioning key 14 on the central shaft 12, as circumferential benchmark.Be provided with pressure ring 15 on top board 9 tops.

During actual job, trim ring 7 on stator lower clamping ring 3, stator punching 16, the stator is overlayed central shaft 12 peripheries on the base plate 1 successively, utilize each locating surface to realize radial location, guarantee its concentricity, and rely on positioning key 14 to realize circumferentially location, be inserted at last top board 9 and pressure ring 15, a whole set of mould is put on the press, press-fit.The utility model takes into full account the stress point of punching in press-fiting process, and stator punching 16 bears uniform pressure under the pressure of press, has guaranteed that the degree of flicking of stator core 5 groove teeth meets specification requirement.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and in the situation of the utility model spirit, the utility model can be done any type of modification.
