【考案の詳細な説明】
本考案は回転電機に係り、鉄心積層作業に使用する鉄心
積層用治具に関するものである。[Detailed Description of the Invention] The present invention relates to a rotating electrical machine, and relates to a core lamination jig used for core lamination work.
回転電機の固定子鉄心は比較的薄い硅素鋼板を素材とし
、これを所定の形状寸法に裁断して作られた部材を、例
えば固定子フレーム内周面に取り付けられている鳩尾状
キーに引掛けながら積層し構成するが、この薄い硅素鋼
板積層の揃いが悪く、板のはみ出しがあると固定子鉄心
のスロット幅寸法が狭くなり所定の幅寸法に絶縁仕上げ
しであるコイルが鉄心のスロットに挿入できない。The stator core of a rotating electric machine is made of a relatively thin silicon steel plate, and the material is cut into a predetermined shape and dimension, and then hooked onto, for example, a dovetail key attached to the inner peripheral surface of the stator frame. However, if the laminated thin silicon steel plates are not aligned properly and the plates protrude, the slot width of the stator core becomes narrow and the coil, which has been insulated to a specified width, is inserted into the slot of the core. Can not.
又スロット内面に薄い板の突出しがあるとコイルの絶縁
被覆を傷つけコイルの絶縁耐力を低下させる等の不具合
が発生する。Further, if the thin plate protrudes from the inner surface of the slot, problems such as damaging the insulation coating of the coil and lowering the dielectric strength of the coil occur.
このため鉄心積層作業は硬質ゴムや革で作られている特
殊ハンマーで鉄心内周面を叩き揃えたり、又スロット寸
法に合せた鋼製角材をコイル構に打ち込むことによって
出来るだけ鉄心を突起部分のない平滑な状態に揃えてい
る。For this reason, core lamination work is done by hammering the inner circumferential surface of the core with a special hammer made of hard rubber or leather, or by driving a steel square piece that matches the slot size into the coil structure, so that the core is as close to the protruding parts as possible. It is not evenly aligned.
この揃え作業は鉄心の積層長さにより異るが数十回の多
くにわたりおこなわれるため鉄心積層作業のなかでも大
きな時間を占めており、又この揃え作業の出来不出来が
固定子鉄心の品質の良否を左右するため熟練者による作
業を要求されている。This alignment work is performed dozens of times, depending on the length of the core stack, so it occupies a large amount of time in the core stacking work, and the quality of the stator core depends on the quality of the alignment work. Because it determines whether the product is good or bad, it requires the work of a skilled person.
本考案は上記したごとく回転電機の鉄心の品質を左右す
る揃え作業を熟練者の技能にのみ頼ることなく均一な品
質を維持し、かつ作業能率を向上する鉄心積層治具を提
供することを目的とする。As mentioned above, the purpose of this invention is to provide an iron core lamination jig that maintains uniform quality and improves work efficiency without relying solely on the skills of experts in the alignment work that affects the quality of the iron core of rotating electric machines. shall be.
以下本考案を示す一実施例について説明する。An embodiment of the present invention will be described below.

、かつ２箇以上のネジ穴１ａを有し適当な長さに作られ
ている。FIG. 1 is a perspective view of the iron core lamination jig according to the present invention, in which the steel wedge 1 has a cross-sectional shape similar to the wedge groove S with a slot, and has two or more screw holes 1a, and has a suitable shape. It is made to a certain length.
Ｔ形バンドルのついた押しネジ２は前記鋼製楔１のネジ
穴１ａにネジ込まれる。A push screw 2 with a T-shaped bundle is screwed into the screw hole 1a of the steel wedge 1.
一方ガイドパー３は断面が短形をなし、その一辺の長さ

作られている。On the other hand, the guide par 3 has a rectangular cross section, and the length A of one side thereof is made smaller than the slot width A' shown in FIG. 2 of the iron core.
第２図は回転電機固定子鉄心部分の構造を示した斜視図
であり固定子リブ４に鳩尾状キー５がネジ止め固定され
ている。FIG. 2 is a perspective view showing the structure of a stator core portion of a rotating electrical machine, in which a dovetail key 5 is fixed to a stator rib 4 with screws.
固定子鉄心の積層組立はこの鳩尾状キー５に所定の寸法
に裁断されている硅素鋼板の打抜板６に形成されている
鳩尾状溝６ａを引掛けながら積層する。The stator core is laminated while the dovetail key 5 is hooked onto the dovetail groove 6a formed in a punched silicon steel plate 6 cut to a predetermined size.
積層していく過程で、前記第１図で説明したガイドバー
３をスロット６ｂの底に固定子鉄心上面より突出するよ
うにセットし、スロット３ｂに挿入した鋼製楔３にネジ

定しておく。During the stacking process, the guide bar 3 explained in FIG. 2, fix the guide bar 3 to the bottom of the slot 6b.
引続き積層していく打抜板６は、このガイドバー３に係
合させて積み上げていくことで容易に打抜板６相互にズ
レが突起部分のない平滑な面に揃えることができる。The punching plates 6 that are to be successively stacked are engaged with the guide bar 3 and piled up, so that the mutual misalignment of the punching plates 6 can be easily aligned to a smooth surface without any protruding parts.
尚本考案の治具は鉄心を積み上げていく過程でガイドバ

びに鉄心積みの作業能率向上に有効である。As explained above, a guide bar with a rectangular cross-sectional shape having a side length smaller than the slot width of the iron core of the present invention is brought into contact with the bottom of the slot, and inserted into the wedge groove of the slot.
In addition, by using a core lamination jig that fixes the idle bar by screwing a push screw into a steel wedge with a screw hole, the inner and outer circumferential surfaces of the core and the inner circumferential surface of the slot can be made smooth and quickly. This makes it possible to stack the cores, which is effective in improving the quality of the core and improving the work efficiency of core stacking.
