Description

本発明は、板材同士を締結する板材締結方法に関し、特に、締結部の表裏に突起を形成することなく板材同士を締結する板材締結方法及び板材締結構造体に関する。   The present invention relates to a plate material fastening method for fastening plate materials together, and more particularly, to a plate material fastening method and a plate material fastening structure for fastening plate materials together without forming protrusions on the front and back sides of a fastening portion.

板材板金同士の締結は、リベットやネジ等によって行うことが一般的であるが、締結部に表裏に突起が存在することが許容できない場合には、専用の設備を使用して、スポット溶接やカシメ等を行う必要があった。   The sheet metal plates are generally fastened with rivets, screws, etc., but if it is not acceptable to have protrusions on the front and back of the fastening part, spot welding or caulking should be performed using dedicated equipment. It was necessary to do etc.

しかし、スポット溶接やカシメを行うためには、比較的大型の設備が必要であり、形状が複雑な大型シャーシへの適用は困難であった。   However, in order to perform spot welding or caulking, a relatively large facility is required, and application to a large chassis having a complicated shape has been difficult.

また、表面処理が施された鋼板に対してスポット溶接を行うと、溶接熱によって表面処理皮膜が消失するため、錆発生の原因となっていた。   In addition, when spot welding is performed on a steel sheet that has been subjected to surface treatment, the surface treatment film disappears due to welding heat, which causes rust generation.

以下、本発明の好適な実施の形態について説明する。   Hereinafter, preferred embodiments of the present invention will be described.

本発明の好適な実施の形態に係る板材締結方法について説明する。
図２に示すように、筒状の突起３を備えた板金１と皿穴４を有する板金２とを締結する。図３に示すように、突起３は皿穴４に窪みが存在しない側から挿入される。突起３の円筒外径と皿穴４の内径とは略同一寸法であり、突起３を皿穴４に挿入した際にがたつきはほとんど生じない。 A plate material fastening method according to a preferred embodiment of the present invention will be described.
As shown in FIG. 2, the sheet metal 1 having the cylindrical protrusion 3 and the sheet metal 2 having the countersink 4 are fastened. As shown in FIG. 3, the protrusion 3 is inserted from the side where the recess does not exist in the countersink 4. The cylindrical outer diameter of the projection 3 and the inner diameter of the countersink 4 are substantially the same size, and when the projection 3 is inserted into the countersink 4, there is almost no rattling.

図４に示すように、ヘッド６を有するシャフト５を板金１の突起３の筒穴に通し、図５に示すようにヘッド６を突起３の端部に突き当てて保持する。ヘッド６のシャフト５との境界部分は、皿穴４に対応するテーパ面が形成されている。   As shown in FIG. 4, the shaft 5 having the head 6 is passed through the cylindrical hole of the projection 3 of the sheet metal 1, and the head 6 is abutted against the end of the projection 3 and held as shown in FIG. 5. A taper surface corresponding to the countersink hole 4 is formed at a boundary portion between the head 6 and the shaft 5.

図６に示すように、シャフト５をリベットツール７に差し込んだのち、図７に示すようにリベットツール７を動作させてシャフト５を引き上げると、皿穴４とヘッド６のテーパ面とに挟まれた突起３は漏斗状に変形する。   As shown in FIG. 6, after inserting the shaft 5 into the rivet tool 7 and operating the rivet tool 7 as shown in FIG. 7 to lift the shaft 5, it is sandwiched between the countersink 4 and the taper surface of the head 6. The protrusion 3 is deformed into a funnel shape.

突起３が皿穴４に密着した状態でシャフト５がさらに引き上げられると、図８に示すようにシャフト５からヘッド６が脱落する。   When the shaft 5 is further pulled up with the protrusion 3 in close contact with the countersink 4, the head 6 falls off the shaft 5 as shown in FIG.

図９（ａ）に、板金１と板金２とを締結した積層体の締結部分の構成を示す。変形した突起３は皿穴４の窪みに収まっており、締結部には出っ張りが存在しない。このため、図９（ｂ）に示すように、締結部の上に安定して部品等を設置できる。   FIG. 9A shows a configuration of a fastening portion of a laminate in which the metal plate 1 and the metal plate 2 are fastened. The deformed protrusion 3 is housed in the recess of the countersunk hole 4, and there is no protrusion on the fastening portion. For this reason, as shown in FIG.9 (b), components etc. can be installed stably on a fastening part.

本実施形態において、シャフトを軸方向に引っ張る作業は、汎用のリベットツールを使用して行えるため、組立作業が容易である。よって、大型シャーシ等の組立に適用することも可能である。
また、締結する板金の機械的強度が低い場合でも突起の裏側を支持すれば板金を変形させることなく締結できる。 In the present embodiment, the work of pulling the shaft in the axial direction can be performed using a general-purpose rivet tool, so that the assembly work is easy. Therefore, it is also possible to apply to assembly of a large chassis or the like.
Further, even when the mechanical strength of the sheet metal to be fastened is low, the sheet metal can be fastened without being deformed by supporting the back side of the protrusion.

また、筒状の突起を皿穴に挿入した状態で締結するため、位置決め作業を省略することが可能である。   Moreover, since it fastens in the state which inserted the cylindrical protrusion in the countersink, it is possible to abbreviate | omit positioning work.

また、締結作業に用いるシャフトは、既存のリベットと比較して単純な形状であるため、部品コストを低減可能である。   Moreover, since the shaft used for the fastening operation has a simple shape as compared with the existing rivet, the part cost can be reduced.

なお、上記実施形態は本発明の好適な実施の一例であり、本発明はこれに限定されることはない。
例えば、上記実施形態においては、２枚の板状部材を締結する構成を例としたが、図１０に示すように、筒状の突起を備えた板状部材と皿穴を備えた板状部材との間に１以上の板状部材を配置することもできる。
また、筒状の突起を押し広げるのに必ずしもヘッドを備えたシャフトを用いる必要はない。また、シャフトを引き上げるのにリベットツール以外の装置を用いても良い。
このように、本発明は様々な変形が可能である。 In addition, the said embodiment is an example of suitable implementation of this invention, and this invention is not limited to this.
For example, in the said embodiment, although the structure which fastens two plate-shaped members was taken as an example, as shown in FIG. 10, the plate-shaped member provided with the cylindrical protrusion and the plate-shaped member provided with the countersink One or more plate-like members can be arranged between the two.
Further, it is not always necessary to use a shaft provided with a head in order to spread the cylindrical protrusion. Moreover, you may use apparatuses other than a rivet tool to pull up a shaft.
As described above, the present invention can be variously modified.
