特開２００７−２２２８８５号公報JP 2007-2222885 A

ところで、上記リベットの先端部分は筒状の同一円周上にあるので、先端部分の拡径変形量が小さく、かしめ幅が小さい。このため、リベットによる部品同士の締結強度が小さく、改善の余地があった。   By the way, since the tip portion of the rivet is on the same cylindrical circumference, the amount of diameter expansion deformation of the tip portion is small and the caulking width is small. For this reason, the fastening strength between parts by rivets is small, and there is room for improvement.

本発明は上記事実を考慮し、部品同士の締結強度を向上させることができる締結具を得ることが目的である。   In view of the above fact, an object of the present invention is to obtain a fastener capable of improving the fastening strength between parts.

請求項１に記載された発明に係る締結具は、表面に外部からの締結圧力を受ける受圧部と、受圧部の裏面に軸方向の一端が接続され、軸方向の他端が締結圧力により第１部材及び第１部材に重合わされた第２部材に挿入される筒状の挿入部と、挿入部の他端の周縁に沿って複数設けられ、他端から挿入部の挿入方向へ突出し、第１部材及び第２部材の内部において挿入部の径方向外側へ変形して第１部材と第２部材とをかしめる刃部位を有するかしめ部と、を備えている。   The fastener according to the first aspect of the present invention has a pressure receiving portion that receives an external fastening pressure on the front surface, one end in the axial direction connected to the back surface of the pressure receiving portion, and the other end in the axial direction caused by the fastening pressure. A cylindrical insertion portion inserted into the first member and the second member overlapped with the first member, and a plurality of insertion portions provided along the periphery of the other end of the insertion portion, projecting from the other end in the insertion direction of the insertion portion, A caulking portion having a blade portion that caulks the first member and the second member by deforming radially outward of the insertion portion inside the first member and the second member is provided.

請求項１に係る締結具は、受圧部、挿入部及びかしめ部を備える。受圧部は、表面に外部からの締結圧力を受ける。挿入部は筒状とされる。挿入部の軸方向の一端は受圧部の裏面に接続される。挿入部の軸方向の他端は締結圧力により第１部材及び第１部材に重合わされた第２部材に挿入される。   The fastener according to claim 1 includes a pressure receiving portion, an insertion portion, and a caulking portion. A pressure receiving part receives the fastening pressure from the outside on the surface. The insertion portion is cylindrical. One end of the insertion portion in the axial direction is connected to the back surface of the pressure receiving portion. The other end in the axial direction of the insertion portion is inserted into the first member and the second member superimposed on the first member by the fastening pressure.

ここで、かしめ部は挿入部の他端の周縁に沿って複数設けられた刃部位を有する。刃部位は挿入部の他端から挿入部の挿入方向へ突出する。このため、複数の刃部位の合計の輪郭線長が長くなるので、刃部位は第１部材及び第２部材の内部において挿入部の径方向外側へ変形し易くなり、第１部材と第２部材とをかしめるかしめ部の径方向外側へのかしめ幅を大きくすることができる。   Here, the caulking portion has a plurality of blade portions provided along the periphery of the other end of the insertion portion. The blade portion protrudes from the other end of the insertion portion in the insertion direction of the insertion portion. For this reason, since the total outline length of a plurality of blade parts becomes long, the blade parts are easily deformed radially outward of the insertion portion inside the first member and the second member, and the first member and the second member It is possible to increase the caulking width of the caulking portion to the outer side in the radial direction.

請求項１に記載された発明に係る締結具は、部品同士の締結強度を向上させることができるという優れた効果を有する。   The fastener according to the invention described in claim 1 has an excellent effect that the fastening strength between components can be improved.

The inside 14C of the insertion portion 14 is a cavity whose upper side is closed by the pressure receiving portion 12 and whose lower side is open.

かしめ部１６は、複数の、本実施の形態では４つの刃部位１６Ａ〜１６Ｄを含んで構成されている。この複数の刃部位１６Ａ〜１６Ｄは、挿入部１４の他端１４Ｂの周縁に沿って、平面視において反時計回りに一定の間隔を持って（ここでは９０度毎に）設けられている。刃部位１６Ａ〜１６Ｄは、側面視において、挿入部１４の挿入方向となる下方向に向かって根元１６Ｕの幅寸法Ｗが小さくなる二等辺三角形状に形成され、下方向先端の刃先１６Ｔは尖っている。刃部位１６Ａの根元１６Ｕは隣接する他の刃部位１６Ｂの根元１６Ｕと連結部１６Ｊを介して連結されている。同様に、刃部位１６Ｂと刃部位１６Ｃとの根元１６Ｕ同士、刃部位１６Ｃと刃部位１６Ｄとの根元１６Ｕ同士及び刃部位１６Ｄと刃部位１６Ａとの根元１６Ｕ同士は、いずれも、連結部１６Ｊを介して連結されている。連結部１６Ｊの上下方向の寸法Ｌ１は、ここでは受圧部１２の外径と挿入部１４の外径との差の２分の１の寸法Ｌ２と同一か、又は寸法Ｌ２よりも大きい寸法とされている。   The caulking portion 16 is configured to include a plurality of four blade portions 16A to 16D in the present embodiment. The plurality of blade portions 16A to 16D are provided along the peripheral edge of the other end 14B of the insertion portion 14 with a constant interval counterclockwise in plan view (here, every 90 degrees). The blade parts 16A to 16D are formed in an isosceles triangle shape in which the width dimension W of the root 16U decreases in the downward direction as the insertion direction of the insertion portion 14 in a side view, and the cutting edge 16T at the tip in the downward direction is sharp. Yes. The root 16U of the blade part 16A is connected to the root 16U of another adjacent blade part 16B via a connecting portion 16J. Similarly, the roots 16U of the blade part 16B and the blade part 16C, the roots 16U of the blade part 16C and the blade part 16D, and the roots 16U of the blade part 16D and the blade part 16A are all connected to the connecting portion 16J.

Here, the vertical dimension L1 of the connecting portion 16J is equal to or larger than the dimension L2 that is a half of the difference between the outer diameter of the pressure receiving portion 12 and the outer diameter of the insertion portion 14. ing.

また、図２（Ｂ）に示されるように、刃部位１６Ａ〜１６Ｄの厚さ方向の断面形状は、挿入方向に向かって厚さが薄くなる形状とされている。詳しく説明すると、刃部位１６Ａ〜１６Ｄは、挿入部１４の他端１４Ｂから刃先１６Ｔに向かって、外壁１６Ｏ側を上下方向に一致させた直線状とし、内壁１６Ｉ側を挿入部１４の中心軸側に突出する円弧状とする断面形状に形成されている。これにより、刃部位１６Ａ〜１６Ｄは、挿入部１４の厚さｔから徐々に厚さを小さくする構成とされている。このような断面形状を備えることにより、かしめによる締結の際に、刃部位１６Ａ〜１６Ｄのそれぞれは、挿入部１４の径方向外側へ変形する構成とされている。   Moreover, as shown in FIG. 2B, the cross-sectional shape in the thickness direction of the blade portions 16A to 16D is a shape in which the thickness decreases toward the insertion direction. More specifically, the blade portions 16A to 16D have a straight shape in which the outer wall 16O side coincides with the vertical direction from the other end 14B of the insertion portion 14 toward the blade edge 16T, and the inner wall 16I side is the central axis side of the insertion portion 14. It is formed in the cross-sectional shape used as the circular arc shape which protrudes in this. Thereby, blade part 16A-16D is set as the structure which reduces thickness gradually from the thickness t of the insertion part 14. FIG. By providing such a cross-sectional shape, each of the blade portions 16 </ b> A to 16 </ b> D is configured to be deformed outward in the radial direction of the insertion portion 14 during fastening by caulking.

そして、挿入部１４の他端１４Ｂと連結部１６Ｊとの境界は、便宜的に破線を用いて示されるように、挿入部１４の円周上に沿ってリンク状に形成されたかしめによる変形開始の起点ＢＬとされている。   The boundary between the other end 14B of the insertion portion 14 and the connecting portion 16J is started by deformation by caulking formed in a link shape along the circumference of the insertion portion 14 as indicated by a broken line for convenience. This is the starting point BL.

（締結具の締結方法）
上記リベット１０を用いた複数部材の締結方法（かしめ方法）は以下の通りである。まず、図３（Ａ）に示されるように、第１部材としての板状の樹脂板２２が第２部材としての板状の金属板２０に重合わされ、樹脂板２２の表面上に本実施の形態に係るリベット１０がセットされる。金属板２０は、樹脂板２２のリベット１０がセットされる側とは反対の裏面に、金属板２０の表面を対向させて重合わされる。金属板２０には、例えば鉄板、アルミニウム合金板等が使用されている。また、金属板２０は板状であるが、第１部材としてはブロック状の部材であってもよい。樹脂板２２には、例えば炭素繊維強化樹脂板、ガラス繊維強化樹脂板等が使用されている。樹脂板２２の厚さは、リベット１０の挿入部１４の軸方向の長さよりも厚く、挿入部１４の軸方向の長さにかしめ部１６の同一方向の長さを加えた長さよりも薄い設定とされている。リベット１０は、かしめ部１６の刃先１６Ｔを下方向へ向け、受圧部１２の表面１２Ａを上方向へ向けてセットされる。 (Fastening method for fasteners)
The fastening method (caulking method) of a plurality of members using the rivet 10 is as follows. First, as shown in FIG. 3A, a plate-like resin plate 22 as a first member is superposed on a plate-like metal plate 20 as a second member, and this embodiment is formed on the surface of the resin plate 22. The rivet 10 according to the form is set. The metal plate 20 is superposed on the back surface of the resin plate 22 opposite to the side on which the rivet 10 is set, with the surface of the metal plate 20 facing. As the metal plate 20, for example, an iron plate, an aluminum alloy plate, or the like is used. Moreover, although the metal plate 20 is plate-shaped, the first member may be a block-shaped member. For the resin plate 22, for example, a carbon fiber reinforced resin plate, a glass fiber reinforced resin plate, or the like is used. The thickness of the resin plate 22 is set to be thicker than the axial length of the insertion portion 14 of the rivet 10 and thinner than the axial length of the insertion portion 14 plus the length of the caulking portion 16 in the same direction. It is said that. The rivet 10 is set with the cutting edge 16T of the caulking portion 16 facing downward and the surface 12A of the pressure receiving portion 12 facing upward.

図３（Ｂ）に示されるように、リベット１０の受圧部１２の表面１２Ａに外部から下方向に作用する締結圧力（締結荷重）Ｆが与えられる。締結圧力Ｆは図示省略のパンチによって与えられる。締結圧力Ｆを受けると、かしめ部１６の刃部位１６Ａ〜１６Ｄのそれぞれの刃先１６Ｔの挿入が樹脂板２２の表面から厚さ方向に向かって開始される。   As shown in FIG. 3B, a fastening pressure (fastening load) F acting downward from the outside is applied to the surface 12A of the pressure receiving portion 12 of the rivet 10. The fastening pressure F is given by a punch (not shown). When receiving the fastening pressure F, the insertion of the blade edges 16T of the blade portions 16A to 16D of the caulking portion 16 starts from the surface of the resin plate 22 in the thickness direction.

引き続き、締結圧力Ｆを受けると、図３（Ｃ）に示されるように、リベット１０の挿入部１４が樹脂板２２の内部へ挿入され、かつ、かしめ部１６が樹脂板２２の裏面側まで挿入される。このとき、リベット１０の挿入により、樹脂板２２の裏面が若干下方向へ突出し（盛り上がり）、金属板２０の表面が下方向へ凹む。上記の通り、かしめ部１６の刃部位１６Ａ〜１６Ｄは、いずれも、内壁１６Ｉが円弧状とされているので、樹脂板２２に挿入されると、挿入部１４の径方向外側へ拡がりながら変形を開始する。この変形は挿入部１４とかしめ部１６との境界となる起点ＢＬを中心として発生する。なお、リベット１０の挿入により、金属板２０の裏面は、樹脂板２２の裏面と同様に、下方向へ突出する。   When the fastening pressure F is subsequently received, the insertion portion 14 of the rivet 10 is inserted into the resin plate 22 and the caulking portion 16 is inserted to the back side of the resin plate 22 as shown in FIG. Is done. At this time, due to the insertion of the rivet 10, the back surface of the resin plate 22 slightly protrudes (swells), and the surface of the metal plate 20 is recessed downward. As described above, the blade portions 16A to 16D of the caulking portion 16 are all deformed while being spread outward in the radial direction of the insertion portion 14 when inserted into the resin plate 22 because the inner wall 16I has an arc shape. Start. This deformation occurs around the starting point BL that becomes the boundary between the insertion portion 14 and the caulking portion 16. As the rivet 10 is inserted, the rear surface of the metal plate 20 protrudes downward, like the rear surface of the resin plate 22.

さらに、締結圧力Ｆを受けると、図３（Ｄ）に示されるように、受圧部１２の裏面１２Ｂが樹脂板２２の表面に当接するまで、リベット１０の挿入部１４及びかしめ部１６が樹脂板２２及び金属板２０に挿入される。このとき、かしめ部１６の刃部位１６Ａ〜１６Ｄは、いずれも、樹脂板２２の突出した部分を介して金属板２０の表面部分に食い込み、かつ、図４に示されるように、挿入部１４の径方向外側へ四方に広がりを持って変形してかしめられる。なお、刃部位１６Ａ〜１６Ｄは、いずれも、樹脂板２２を貫通して直接金属板２０に食い込んでもよい。そして、かしめが完了すると、樹脂板２２はリベット１０を用いて金属板２０に締結され、更にリベット１０を用いて樹脂板２２が金属板２０に締結された締結構造が完成する。   Further, when the fastening pressure F is received, the insertion portion 14 and the caulking portion 16 of the rivet 10 are placed on the resin plate until the back surface 12B of the pressure receiving portion 12 contacts the surface of the resin plate 22 as shown in FIG. 22 and the metal plate 20. At this time, the blade portions 16A to 16D of the caulking portion 16 all bite into the surface portion of the metal plate 20 through the protruding portion of the resin plate 22, and as shown in FIG. It is deformed and caulked with a spread in all directions radially outward. Note that all of the blade portions 16A to 16D may penetrate the resin plate 22 and bite into the metal plate 20 directly. When the caulking is completed, the resin plate 22 is fastened to the metal plate 20 using the rivet 10, and the fastening structure in which the resin plate 22 is fastened to the metal plate 20 using the rivet 10 is completed.

（本実施の形態の作用及び効果）
以上説明したように、本実施の形態に係るリベット１０は、図１、図２（Ａ）及び図２（Ｂ）に示されるように、受圧部１２、挿入部１４及びかしめ部１６を備える。受圧部１２は表面１２Ａに外部からの締結圧力Ｆを受ける。挿入部１４は筒状とされる。挿入部１４の軸方向の一端１４Ａは受圧部１２の裏面１２Ｂに接続される。挿入部１４の軸方向の他端１４Ｂは、図３（Ｂ）及び図３（Ｃ）に示されるように、締結圧力Ｆにより樹脂板２２及びこの樹脂板２２に重合わされた金属板２０に挿入される。 (Operation and effect of the present embodiment)
As described above, the rivet 10 according to the present embodiment includes the pressure receiving portion 12, the insertion portion 14, and the caulking portion 16 as shown in FIGS. 1, 2A, and 2B. The pressure receiving portion 12 receives an external fastening pressure F on the surface 12A. The insertion portion 14 is cylindrical. One end 14 </ b> A in the axial direction of the insertion portion 14 is connected to the back surface 12 </ b> B of the pressure receiving portion 12. As shown in FIGS. 3B and 3C, the other end 14B in the axial direction of the insertion portion 14 is inserted into the resin plate 22 and the metal plate 20 superposed on the resin plate 22 by the fastening pressure F. Is done.

ここで、かしめ部１６は、挿入部１４の他端１４Ｂの周縁に沿って複数設けられた刃部位１６Ａ〜１６Ｄを含んで構成される。刃部位１６Ａ〜１６Ｄは、他端１４Ｂから挿入部１４の挿入方向（下方向）へ突出する。このため、かしめ部１６の複数の刃部位１６Ａ〜１６Ｄの合計の輪郭線長１６Ｌが、挿入方向に稼げるので、例えば刃部位１６Ａ〜１６Ｄが設けられていない場合に比べて、長くなる。   Here, the caulking portion 16 includes a plurality of blade portions 16 </ b> A to 16 </ b> D provided along the periphery of the other end 14 </ b> B of the insertion portion 14. Blade part 16A-16D protrudes in the insertion direction (downward direction) of the insertion part 14 from the other end 14B. For this reason, since the total outline length 16L of the plurality of blade portions 16A to 16D of the caulking portion 16 can be earned in the insertion direction, for example, it becomes longer than the case where the blade portions 16A to 16D are not provided.

図３（Ｄ）及び図４に示されるように、輪郭線長１６Ｌが長くなるのと、樹脂板２２及び金属板２０の内部において、刃部位１６Ａ〜１６Ｄは径方向外側へ変形し易くなる。これにより、樹脂板２２と金属板２０とをかしめるかしめ部１６の径方向外側へのかしめ幅Ｗｃを大きくすることができる。かしめ幅Ｗｃは、詳しく説明すると、基本かしめ幅Ｗ１と増加かしめ幅Ｗ２との合計の寸法である。基本かしめ幅Ｗ１は、起点ＢＬから刃部位１６Ａ〜１６Ｄの根元１６Ｕまでの部位において、挿入部１４の外壁から挿入部１４の径方向外側へ拡径変形された寸法である。この基本かしめ幅Ｗ１は、受圧部１２の外径と挿入部１４の外径との差の２分の１の寸法Ｌ２とほぼ等しく、従来の自己穿孔型リベットのかしめ幅に一致する。一方、増加かしめ幅Ｗ２は、基本かしめ幅Ｗ１に加えて、刃部位１６Ａ〜１６Ｄの拡径変形により増加される寸法である。   As shown in FIG. 3D and FIG. 4, when the contour length 16L is increased, the blade portions 16A to 16D are easily deformed radially outward in the resin plate 22 and the metal plate 20. As a result, the caulking width Wc of the caulking portion 16 that caulks the resin plate 22 and the metal plate 20 outward in the radial direction can be increased. More specifically, the caulking width Wc is the total dimension of the basic caulking width W1 and the increased caulking width W2. The basic caulking width W1 is a dimension that is expanded and deformed from the outer wall of the insertion portion 14 to the radially outer side of the insertion portion 14 in a portion from the starting point BL to the root 16U of the blade portions 16A to 16D. This basic caulking width W1 is substantially equal to the dimension L2 that is a half of the difference between the outer diameter of the pressure receiving portion 12 and the outer diameter of the insertion portion 14, and matches the caulking width of the conventional self-piercing rivet. On the other hand, the increased caulking width W2 is a dimension that is increased by the diameter expansion deformation of the blade portions 16A to 16D in addition to the basic caulking width W1.

従って、本実施の形態に係るリベット１０では、かしめ幅Ｗｃを増加させてかしめ面積（図４にハッチングを付して示される食い込み面積）が増加するので、金属板２０及び樹脂板２２の部品同士の締結強度を向上させることができる。   Therefore, in the rivet 10 according to the present embodiment, the caulking width Wc is increased to increase the caulking area (the bite area shown by hatching in FIG. 4). The fastening strength of can be improved.

また、本実施の形態に係るリベット１０は、かしめ部１６の刃部位１６Ａ〜１６Ｄの刃先１６Ｔが尖った形状とされているので、樹脂板２２及び金属板２０に挿入し易い。このため、締結作業が安定に行える。   In addition, the rivet 10 according to the present embodiment is easy to insert into the resin plate 22 and the metal plate 20 because the cutting edges 16T of the blade portions 16A to 16D of the caulking portion 16 have a sharp shape. For this reason, a fastening operation can be performed stably.

［上記実施の形態の補足説明］
