いう欠点があった。(Prior Art) In the past, as disclosed in Japanese Patent Application Laid-Open No. 60-118387, a small ring is projected all around the welding surface of the nut and a core rod made of heat-resistant porcelain is provided in the screw hole. The nut was arc stud welded while the nut was bited through the arc stud welding gun through the arc and turned around the entire circumference of the welding surface along the ring to prevent the arc from entering the screw hole by the core rod. . However, when welding this kind of nut, a core rod made of heat-resistant porcelain must be used without fail, and the handling thereof is troublesome.
（技術的課題） 而して、本考案は従来技術の欠点に鑑みなされたもので
ナットを煩雑な手間をなくして比較的簡単に対象物へ位
置合わせするとともにアークスタッド溶接とすることが
出来るようにすることを技術的課題とするものである。(Technical problem) Therefore, the present invention has been made in view of the drawbacks of the prior art, so that the nut can be relatively easily aligned with the object and arc stud welding can be performed without complicated labor. It is a technical subject to make it.
（技術的手段） 本考案では上記の技術的課題を解決するためにナットの
螺孔内に筒状の絶縁体を嵌着せしめ、この絶縁体の鍔部
を、突設した溶接部より更に突出させてある。具体的に
は図示の実施例に示す如く下記の構成となる。(Technical Means) In the present invention, in order to solve the above technical problem, a tubular insulator is fitted in the screw hole of the nut, and the collar portion of this insulator is further projected from the protruding welded portion. I am allowed. Specifically, it has the following configuration as shown in the illustrated embodiment.
１は鋼製のナット本体で螺孔２を形成してある。Reference numeral 1 is a steel nut body having a screw hole 2 formed therein.
３はナット本体１の溶接面４に突設した環状の溶接部で
母材としての鋼板等の対象物体５にアークスタッド溶接
されるものである。Reference numeral 3 denotes an annular weld portion projectingly provided on the welding surface 4 of the nut body 1 and is arc stud welded to a target object 5 such as a steel plate as a base material.
６はナイロン合成樹脂等で形成した筒状又は輪状の絶縁
体でナット本体１の螺孔２に嵌着してある。Reference numeral 6 denotes a tubular or ring-shaped insulator made of nylon synthetic resin or the like, which is fitted into the screw hole 2 of the nut body 1.
而して、この絶縁体６の螺孔２への嵌着によりアークス
タッド溶接銃によるアークスタッド溶接時にスパッタが
螺孔２内へ入り込むのを防止している。The fitting of the insulator 6 into the screw hole 2 prevents spatter from entering the screw hole 2 during arc stud welding by the arc stud welding gun.
７は対象物体５に穿った貫通孔である。Reference numeral 7 is a through hole formed in the target object 5.
第３図に示した絶縁体６はナット本体１の頂面８まで延
長してあるが適宜、短かくして螺孔２の途中で終るよう
にしてもよい。Although the insulator 6 shown in FIG. 3 extends to the top surface 8 of the nut body 1, it may be appropriately short and may end in the middle of the screw hole 2.
本考案においては、上記絶縁体６に鍔部６Ａを設けてあ
り、しかもこの鍔部を突設した溶接部３より更に突出さ
せてある。In the present invention, the insulator 6 is provided with the flange portion 6A, and further, the flange portion is further projected from the welded portion 3 provided in a protruding manner.
この絶縁体６の材質、形状、寸法等は適宜変更し得るも
ので図面に開示したものだけに限定するものではない。The material, shape, dimensions, etc. of the insulator 6 can be changed as appropriate and are not limited to those disclosed in the drawings.
（作用） 上記の技術的手段は下記の如く作用する。(Operation) The above technical means operates as follows.
予め、筒状又は輪状の絶縁体６をナット本体１の螺孔２
内に嵌着せしめておく。In advance, the tubular or annular insulator 6 is attached to the screw hole 2 of the nut body 1.
Keep it fitted inside.
然る後、ナット本体１をアークスタッド溶接銃（図示せ
ず）にかませて対象物体５上に位置付けし、アークスタ
ッド溶接を行えばよい。After that, the nut body 1 may be bitten by an arc stud welding gun (not shown), positioned on the target object 5, and arc stud welding may be performed.
この際絶縁体６の突出した鍔部６Ａが対象物５の貫通孔
７内に位置付けるから、ナットの溶接位置合わせが容易
である。At this time, since the protruding collar portion 6A of the insulator 6 is positioned inside the through hole 7 of the object 5, the welding position alignment of the nut is easy.
然る時、アークは環状の溶接部３に廻り、スパッタが絶
縁体６の存在により螺孔２内へ入り込むことがない。ナ
ット本体１の対象物体５への溶接後は絶縁体６はそのま
ま螺孔２内に残しておき、ボルト９を絶縁体６ごと螺着
せしめる。At that time, the arc goes around the annular weld portion 3 and the spatter does not enter the screw hole 2 due to the presence of the insulator 6. After welding the nut body 1 to the target object 5, the insulator 6 is left in the screw hole 2 as it is, and the bolt 9 is screwed together with the insulator 6.
然る後、この絶縁体６はねじの緩み止め機能を発揮する
こととなる。After that, the insulator 6 exerts a screw loosening preventing function.
（効果） 而して、本考案は叙上の如き構成及び作用を有するので
下記の如き効果がある。(Effects) Since the present invention has the above-described configuration and operation, it has the following effects.
（ａ）ナット本体の螺孔に筒状の絶縁体を嵌着してある
のでアークスタッド溶接時にスパッタが螺孔内に入り込
むのを防止できる。(A) Since the tubular insulator is fitted in the screw hole of the nut body, spatter can be prevented from entering the screw hole during arc stud welding.
（ｂ）ナット本体を対象物体へ溶接した後にも絶縁体が
螺孔内に存在するのでボルトを螺着した際の緩み止め機
能を発揮し得る。(B) Since the insulator exists in the screw hole even after the nut body is welded to the target object, the loosening prevention function can be exhibited when the bolt is screwed.
（ｃ）さらに絶縁体６の突出する鍔部６Ａにより、溶接
対象物体の貫通孔と相まって、ナットの溶接位置合わせ
を容易とすることができた。(C) Further, due to the protruding collar portion 6A of the insulator 6, the welding position of the nut can be easily aligned with the through hole of the object to be welded.
