本発明は、位置決めビン、詳しくは、例えば自動車等の
製造工程において、板金の位置決めを行いそれを溶接す
る際に使用される位置決めビンに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a positioning bin, and more particularly, to a positioning bin used for positioning and welding sheet metal in the manufacturing process of, for example, automobiles.
従来、位置決めビンは545Cなどの金属が使用されて
いるが、耐摩耗性や耐蝕性が十分でないので板金枚数が
5.000〜50.000枚程度の取扱量で寿命となる
欠点があった。Conventionally, metal such as 545C has been used for positioning bins, but this has the drawback that it does not have sufficient abrasion resistance or corrosion resistance, and its lifespan is limited to approximately 5,000 to 50,000 sheets.
窒化ケイ素やサイアロンなどのセラミックスは高強度、
高耐蝕性、高硬度、高耐摩耗性、軽量などの特性を有す

・抜き出し時の機械的衝撃で破損し溶接工程がストップ
し金属質のものよりも寿命が短い場合があるなどの問題
点があった。Ceramics such as silicon nitride and sialon have high strength,
It has properties such as high corrosion resistance, high hardness, high wear resistance, and light weight, so it is being considered as a material for positioning bottles. However, even when ceramics are used for positioning bins, there are problems such as damage due to mechanical shock when loading and unloading sheet metal, stopping the welding process, and resulting in a shorter service life than metal ones.
本発明者らは、従来の位置決めビンの欠点を解決するこ

ある。As a result of various studies aimed at solving the drawbacks of conventional positioning bottles, the inventors of the present invention made the positioning part of the positioning bottle made of ceramic, the fixing part and the introduction part made of metal, and in addition, the shaft of the introduction part was made of metal. The fixing part and the introduction part are fixed with a soldered screw part provided in the
The present invention was completed based on the discovery that a long life can be achieved without damage caused by mechanical impact during extraction.

決めビンである。That is, in the present invention, the shaft portion 4 of the metallic introduction member is inserted into the through hole of the ceramic positioning member 2, and the shaft portion 4 is inserted into the through hole of the ceramic positioning member 2.
This is a positioning bottle characterized in that a metal introducing member 3 and a metal fixing member 1 are screwed together by a soldered screw portion 5 provided in the holder.
以下、本発明を図面に従ってさらに詳しく説明する。第
1図は、本発明の位置決めビンの一実施例を示す一部切
欠断面図である。Hereinafter, the present invention will be explained in more detail with reference to the drawings. FIG. 1 is a partially cutaway sectional view showing an embodiment of the positioning bin of the present invention.

位置決め部材20貫通孔に導入部材の軸部4を挿通させ
て導入部材3と固定部材1とを半田付きネジ部5により
螺着してなる構造を有するものである。The positioning bottle of the present invention is composed of a metal fixing member l, a ceramic positioning member 2 having a through hole, and a metal introduction member 3 having a shaft portion 4 of the metal introduction member, and the shaft portion 4 is soldered. It is provided with a threaded portion 5. Specifically, the positioning member 2 is positioned on the upper surface of the fixing member l, the shaft portion 4 of the introducing member is inserted into the through hole of the positioning member 20, and the introducing member 3 and the fixing member 1 are screwed together with the soldered screw portion 5. It has the following structure.
本発明の特徴の一つは、導入部材3と固定部材lを位置
決め部材2を挟んで固定する際に、半田付きネジ部5を
用いたことである。このようにすることによって、板金
の装入・抜き出し時の機械的衝撃によるネジ部の緩みが
発生しにくいものとなる。半田としては、固定状のもの
もあるが特に金属粉とフラックスを混合してなるペース
ト状のものはネジ部に均一に塗布でき作業性もよいので
好適である。One of the features of the present invention is that a soldered screw portion 5 is used when fixing the introducing member 3 and the fixing member l with the positioning member 2 interposed therebetween. By doing this, the threaded portion is less likely to loosen due to mechanical impact when loading and unloading the sheet metal. As the solder, there is a fixed type of solder, but a paste type of solder made by mixing metal powder and flux is particularly suitable because it can be uniformly applied to the threaded portion and has good workability.
半田付きネジ部のかわりに有機系接着剤や溶接による固
定があるが、それらでは不十分である。Organic adhesives or welding are used instead of soldered screws, but these are insufficient.
すなわち、有機系接着剤は、熱により炭化し緩み防止効
果を発揮しなくなり、使用時の溶接の熱により耐久性が
劣る。一方、溶接は、ネジ部の固定力は半田と同等に強
力であるが、大きなトルクを加え、−旦緩みが発生する
と急激に固定力が低下し緩み防止効果を発揮しなくなる
。That is, organic adhesives are carbonized by heat and no longer exhibit a loosening prevention effect, and their durability is degraded by the heat of welding during use. On the other hand, welding has the same strong fixing force as soldering for threaded parts, but when a large torque is applied and loosening occurs, the fixing force rapidly decreases and the loosening prevention effect is no longer exhibited.
位置決め部材2を固定部材1の上面に位置させるに際し
、第1図に示すように、位置決め部材2の外周直胴部の
一部が固定部材1の内部に組み込んだ構造にすることが
望ましい。このようにすることによって、位置決め部材
2と同定部材lの中心軸が一致しやすくなるので、使用
時における板金からの外力によって位置決め部材2がず
れることはない。When positioning the positioning member 2 on the upper surface of the fixing member 1, it is desirable to have a structure in which a part of the outer circumference of the body of the positioning member 2 is incorporated into the interior of the fixing member 1, as shown in FIG. By doing so, the central axes of the positioning member 2 and the identification member 1 are easily aligned, so that the positioning member 2 will not be displaced by external force from the sheet metal during use.

状については、内部に貫通孔を有したものであればよく
、その外周形状には制限はない。溶接される板金等の穴
形状に応じて円形や多角形などが採用される。The material for the positioning member 2 is selected from ceramic materials such as silicon nitride, sialon, zirconia, alumina, and silicon carbide, with silicon nitride being preferred from the viewpoint of wear resistance and corrosion resistance. Ceramic sintering methods include pressureless sintering, hot pressing, H
You can choose from IP. Further, the shape of the positioning member 2 may be any shape as long as it has a through hole inside, and there is no restriction on the outer peripheral shape thereof. A circular or polygonal shape is used depending on the shape of the hole in the sheet metal etc. to be welded.
導入部材3はネジ部5を備えた軸部4を有しているが、
両者は一体成形物である必要はない。両者を別々に製作
し一体化したものでもよく、また、その際、両者の材質
を違えたものであってもよい。The introduction member 3 has a shaft portion 4 equipped with a threaded portion 5,
Both do not need to be integrally molded. Both may be manufactured separately and integrated, or in that case, they may be made of different materials.

ボルトやリベットの使用ができるように頭部が平伏又は
半球状であってもよい。It is desirable that the introduction member 3 includes a straight body portion 7 having the same outer circumference as the positioning member 2 . The reason for this is that if the straight body part 7 is not provided, that is, if the diameters of either of the outer circumference straight bodies of the positioning member 2 and the introduction member 3 are different and there is a step, when loading and unloading the sheet metal, This is because there is a possibility that a direct impact will be applied to the positioning member 2. Further, it is desirable that the introducing member 3 has a tapered portion 6, which makes it easier to insert and extract the sheet metal. There are no particular restrictions on the shape of the tapered portion 6, and the head may be flat or hemispherical so that commercially available bolts and rivets can be used.

ずしも必要でない。In order to attach the positioning bottle of the present invention to a welding machine (not shown), etc., it is recommended that the fixing member l be provided with means for attaching the threaded portion 8 or a portion of the taper (not shown). desirable. Of course, installation can be done by welding or
The positioning bin of the present invention can also be attached by gluing or the like. Although the head of the fixing member 1 shown in FIG. 1 has a shape expanded in the outer circumferential direction, this is a measure for convenient attachment to a welding machine, etc., and is not necessarily necessary in the present invention.
