Description
Technical field
The utility model relates to technical field of generators, is specifically related to a kind of hexagonal generator stator core.
Background technology
Existing generator iron-core reserves triangle in the centre of the stator punching cylindrical planar slot of generator, the projections such as rectangle, bumps melt on lamination is formed longitudinal attachment weld by the heat only relying on TIG electric arc to produce, the several size according to iron core of weld seam and fastening requirements and determine, be generally 4-6 bar Central Symmetry distribution welding, and will circle end face weld several iron bar having kidney slot be convenient to iron core lifting.Stator core cylindrical and round base endoporus adopt press-loading process to form main frame field frame assembly, and with screw lock iron core stator core.
The major defect of this iron core is: the stator core teeth portion amount of flicking is large, and iron core vortex loss is comparatively large, causes electric machine temperature rise higher.Can welding deformation be there is during stator core welding, cause rotor and stator disalignment.What serious meeting caused motor sweeps boring accident.Production process is more, and manufacturing cost is high, and efficiency is low.Along with expanding economy, the power of motor can be increasing, and the length of iron core is more and more longer, and external diameter is also increasing, round base endoporus and two ends seam to add man-hour more difficult, be difficult to the requirement ensureing two ends axiality.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of production efficiency high, and processing cost is low, and location is reliable, and axiality is high, installs more convenient, effectively solves the hexagonal generator stator core of the teeth portion amount of flicking problem.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of hexagonal generator stator core, comprise iron core, positioner that is some and iron mandrel's line parallel is set outside the iron core described in it, described positioner is fixedly connected with by the forward and backward end ring that its two ends and iron core are coaxial, described positioner arranges hole for hoist, described forward and backward end ring is disk or ring flange, correspondingly on described disk or ring flange arranges the fixing hole being used for stationary positioned device.
Above-mentioned a kind of hexagonal generator stator core, the positioner described in it is the pole that length is equal.
Above-mentioned a kind of hexagonal generator stator core, the pole described in it is welded in outside iron core by pad.
Above-mentioned a kind of hexagonal generator stator core, the pole described in it is uniformly distributed in outside iron core.
Above-mentioned a kind of hexagonal generator stator core, the pole quantity described in it is 4-8 root.
Above-mentioned a kind of hexagonal generator stator core, the positioner described in it is fixedly welded on outside iron core by carbon dioxide gas arc welding.
Above-mentioned a kind of hexagonal generator stator core, the positioner described in it and the weld seam quantity between iron core are 4-6 bar, and weld seam is symmetrical about iron core axis.
Beneficial effect:
The utility model arranges positioner outside iron core, and positioner welding edges fixes end ring, and after having welded, by iron core Internal hole positioning, end ring seam before and after processing, ensures iron core concentricity.Its production work efficiency improves, and processing cost reduces, and hexangle type location is reliable, and axiality consistency is good, installs fixing more convenient, successfully solves the problem of the teeth portion amount of flicking, the amount of flicking is controlled in the margin of tolerance.And the requirement reduced weld jig precision, copies fixture more for convenience.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Wherein, 1, front welded flange, 2, iron core, 3, pad, 4, pole, 5, rear welded flange.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1; the utility model comprises iron core 2; 6 equal poles 4 of length are set outside iron core 2 as positioner; pole 4 and iron core 2 axis being parallel; 6 poles 4 are parallel to each other, and 6 poles 4 pass through 24 pad 3 uniform weldings outside iron core 2, and welding adopts carbon dioxide gas arc welding welding; weld seam quantity is 4-6 bar, and weld seam is symmetrical about iron core axis.Pole 4 is fixedly connected with by the coaxial front welded flange 1 of its two ends and iron core 2, rear welded flange 5, correspondingly on front welded flange 1 and rear welded flange 5 arranges the fixing hole 7 being used for fixing pole 4, pole 4 is arranged some holes for hoist 6.
The utility model cancels the iron plate of the outer round belt kidney slot of iron core, what replace it is pole, welding cushion block and iron core three are welded to each other, bonding area is less, corresponding thermal deformation will reduce, and according to the size of deflection, can when producing, pole locating ring is have employed, top pole cover loop mapping in fixture bottom.Solve pole thermal deformation to shrink, the deviation of the centre-to-centre spacing caused.For ensureing the requirement of iron core and six roots of sensation pole axiality, iron core and pole overlap loop mapping and adopt unifying datum principle, the angle location of six roots of sensation pole then have employed and add a mandrel in iron core, and fixing fagging and movable fagging are installed on mandrel, one of them fixing fagging outputs keyway to limit angle location.Decrease the precision that resetting and foozle effectively ensure that fixture.Clamp have employed hydraulic cylinder, and hydraulic cylinder thrust is steady, pressure controllable.Decrease the teeth portion amount of flicking.Rely on carbon dioxide gas arc welding, welding gun welding machine negative pole, stator core welder positive pole.The several size according to iron core of weld seam and fastening requirements and determine, be generally the distribution of 4-6 bar Central Symmetry.Through test of many times, add two weld seams in iron core two sides, successfully can solve the problem of the teeth portion amount of flicking, the amount of flicking is controlled in the margin of tolerance.Welded flange ring before and after pole, after having welded, with iron core endoporus for benchmark, by vertical lathe, flange ring seam before and after processing.Ensure that the concentricity of front and back welded flange seam and iron core endoporus.
The utility model production work efficiency improves, and processing cost reduces, and hexangle type location is reliable, and axiality consistency is good, installs fixing more convenient, successfully solves the problem of the teeth portion amount of flicking, the amount of flicking is controlled in the margin of tolerance.And the requirement reduced weld jig precision, copies fixture more for convenience.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
