発明を実施するための最良の形態 BEST MODE FOR CARRYING OUT THE INVENTION

[0033] 以下、本発明の実施の形態を図面に基づき説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0034] 図 1は本発明の部材接合構造の第 1の例である。 FIG. 1 shows a first example of the member joining structure of the present invention.

[0035] この部材接合構造は、面接触するように重ねた板状の第 1、第 2の被接合部材 1 , 2と、第 2の被接合部材 2とは真反対に位置するように第 1の被接合部材 1に当接する締結部材 5と、補助部材 7とを備えている。 This member joining structure is formed so that the plate-like first and second members to be joined 1 and 2 and the second member to be joined 2 are positioned so as to be opposite to each other. A fastening member 5 that comes into contact with one member 1 to be joined and an auxiliary member 7 are provided.

[0036] 補助部材 7はアルミニウム合金を素材とし、第 2の被接合部材 2と締結部材 5は、アルミニウム合金よりも硬く且つ軟化温度が高い鋼を素材としている。 [0036] The auxiliary member 7 is made of an aluminum alloy, and the second member 2 and the fastening member 5 are made of steel that is harder and higher in softening temperature than the aluminum alloy.

[0037] 第 1、第 2の被接合部材 1 , 2には部材厚み方向に貫通する孔 3 , 4が、同軸に穿設してある。 [0037] The first and second members to be joined 1 and 2 have holes 3 and 4 that penetrate in the thickness direction of the member and are coaxially formed.

[0038] 締結部材 5には部材厚み方向に貫通するねじ孔 2 0力前記第 1、第 2の被接合部材 1 , 2の孔 3 , 4と同軸に位置するように穿設してある。 The fastening member 5 has a screw hole 20 force penetrating in the member thickness direction so as to be positioned coaxially with the holes 3 and 4 of the first and second members to be joined 1 and 2.

[0039] 上記ねじ孔 2 0は、部材厚み方向へ貫通しないねじ穴であってもよく、締結部材 5としては、ナツトゃ袋ナツトを利用することができる。 [0039] The screw hole 20 may be a screw hole that does not penetrate in the thickness direction of the member, and a nut bag nut can be used as the fastening member 5.

[0040] 図 1 ( a ) に示すように、ねじ孔 2 0、及び孔 3 , 4には補助部材 7が差し込まれる。 [0040] As shown in FIG. 1 (a), the auxiliary member 7 is not connected to the screw hole 20 and the holes 3 and 4. It is inserted.

[0041 ] 締結部材 5は、第 1の被接合部材 1に溶接などの手法により予め固着しておいてもよい。 [0041] The fastening member 5 may be fixed to the first member 1 to be joined in advance by a technique such as welding.

[0042] 図 1 ( d ) に示すように、補助部材 7に由来する材料は、摩擦熱と塑性流動によって、締結部材 5のねじ孔 2 0内周面、及び第 1、第 2の被接合部材 1 , 2の孔 3 , 4内周面のそれぞれに密着し且つ当該第 2の被接合部材 2の孔 4の周囲を覆うように形作られ、補助部材 7が第 1、第 2の被接合部材 1 , 2を接合している。 [0042] As shown in FIG. 1 (d), the material derived from the auxiliary member 7 is made of frictional heat and plastic flow, so that the screw hole 20 inner peripheral surface of the fastening member 5 and the first and second coverings are formed. The auxiliary members 7 are formed so as to be in close contact with the inner peripheral surfaces of the holes 3 and 4 of the bonding members 1 and 2 and to cover the periphery of the holes 4 of the second bonded member 2. The joining members 1 and 2 are joined.

[0043] 補助部材 7を上述したような形状とする際には、裏当て部材 6と接合ツーゾレ 1 0を用いる。 [0043] When the auxiliary member 7 is shaped as described above, the backing member 6 and the bonding tool 10 are used.

[0044] 裏当て部材 6と接合ツール 1 0は、アルミニウム合金よりも硬く且つ軟化温度が高い鋼を素材としている。 [0044] The backing member 6 and the joining tool 10 are made of steel that is harder than an aluminum alloy and has a higher softening temperature.

[0045] 接合ツール 1 0は、短円柱状のピン部 8を円柱状のショルダ部 9の先端面に同軸に連ねた形をしており、また、裏当て部材 6は、締結部材 5と補助部材 7を受ける役割をする。 [0045] The welding tool 10 has a shape in which a short cylindrical pin portion 8 is coaxially connected to the tip surface of the cylindrical shoulder portion 9, and the backing member 6 is an auxiliary member with the fastening member 5. Plays the role of receiving part 7.

[0046] 裏当て部材 6で保持されている補助部材 7の第 2の被接合部材 2側の端面に、接合ツール 1 0を回転させながら押し付けると、図 1 ( b ) に示すように、補助部材 7が摩擦熱と塑性流動により軟化する。 [0046] When the welding tool 10 is pressed against the end surface of the auxiliary member 7 held by the backing member 6 on the second member-to-be-joined 2 side while rotating, as shown in FIG. The member 7 is softened by frictional heat and plastic flow.

[0047] この後、図 1 ( c ) に示すように、補助部材 7に由来する材料が、ねじ孔Thereafter, as shown in FIG. 1 (c), the material derived from the auxiliary member 7 becomes screw holes.

2 0のねじ溝に入り込み、第 2の被接合部材 2の孔 4の周囲を覆う。 It enters the 20 screw groove and covers the periphery of the hole 4 of the second member 2 to be joined.

[0048] 更に、図 1 ( d ) に示すように、接合ツール 1 0を補助部材 7から引き離して、孔 4を覆う補助部材 7の塑性流動部位、及びねじ孔 2 0に密着した補助部材 7の塑性流動部位を硬化させると、第 1、第 2の被接合部材 1 , 2の接合が完了する。 Further, as shown in FIG. 1 (d), the welding tool 10 is pulled away from the auxiliary member 7, and the plastic flow site of the auxiliary member 7 covering the hole 4 and the screw hole 20 are in close contact with each other. When the plastic flow site of the auxiliary member 7 is cured, the joining of the first and second joined members 1 and 2 is completed.

[0049] つまり、第 1の被接合部材 1の素材が、第 2の被接合部材 2と同じ鋼でも、あるいは鋼以外の硬さや軟化温度などの物性が著しく違う異種材であっても、これらの部材 1 , 2を効率よく且つ確実に接合することができる。 That is, even if the material of the first member to be bonded 1 is the same steel as the second member to be bonded 2, or even a dissimilar material having significantly different physical properties such as hardness and softening temperature other than steel. The members 1 and 2 can be joined efficiently and reliably.

[0050] また、第 1の被接合部材 1の素材が補助部材 7と同じアルミニウム合金であれば、補助部材 7に由来する材料が第 1の被接合部材 1に同化する。 [0050] The material of the first member 1 to be joined is the same aluminum alloy as that of the auxiliary member 7. If there is, the material derived from the auxiliary member 7 is assimilated to the first member 1 to be joined.

[0051 ] この他に、第 2の被接合部材 2に対して第 1の被接合部材 1が薄手である場合、第 1の被接合部材 1に締結部材 5を溶接などの手法で予め固着しておけば、締結部材 5によって補助部材 7に加わる剪断力が分散され、第 1、第[0051] In addition to this, when the first member 1 to be joined is thin with respect to the second member 2, the fastening member 5 is fixed to the first member 1 in advance by a technique such as welding. Then, the shearing force applied to the auxiliary member 7 is dispersed by the fastening member 5, and the first and first

2の被接合部材 1 , 2に互いにずれる方向への力が働いても補助部材 7が破断せず、第 1の被接合部材 1の剥離も防止できる。 Even if a force in a direction in which the two members 1 and 2 are displaced from each other is applied, the auxiliary member 7 is not broken, and the first member 1 can be prevented from peeling off.

[0052] 図 2は本発明の部材接合構造の第 2の例であり、図中、図 1 と同一の符号を付した部分は同一物を表している。 FIG. 2 shows a second example of the member joining structure of the present invention. In the figure, the parts denoted by the same reference numerals as those in FIG. 1 represent the same items.

[0053] この部材接合構造は、面接触するように重ねた板状の第 1、第 2の被接合部材 1 , 2 1 と、第 2の被接合部材 2 1 とは真反対に位置するように第 1の被接合部材 1に当接する締結部材 5と、補助部材 7とを備えている。 [0053] In this member joining structure, the plate-like first and second joined members 1 and 2 1 stacked so as to be in surface contact with each other are positioned so as to be opposite to the second joined member 2 1. In addition, a fastening member 5 that comes into contact with the first member 1 to be joined and an auxiliary member 7 are provided.

[0054] 第 2の被接合部材 2 1 と補助部材 7はアルミニウム合金を素材とし、締結部材 5は、アルミニウム合金よりも硬く且つ軟化温度が高い鋼を素材としている。 [0054] The second member 2 1 and the auxiliary member 7 are made of an aluminum alloy, and the fastening member 5 is made of steel that is harder and higher in softening temperature than the aluminum alloy.

[0055] 第 1、第 2の被接合部材 1 , 2 1には部材厚み方向に貫通する孔 3 , 2 2 力同軸に穿設してある。 [0055] The first and second members to be joined 1 and 21 are bored coaxially with holes 3 and 2 2 which penetrate in the thickness direction of the member.

[0056] 締結部材 5には部材厚み方向に貫通するねじ孔 2 0力前記第 1、第 2の被接合部材 1 , 2 1の孔 3 , 2 2と同軸になるように位置させてある。 A screw hole 20 force penetrating in the thickness direction of the fastening member 5 is positioned so as to be coaxial with the holes 3 and 2 2 of the first and second members to be joined 1 and 21.

[0057] 図 2 ( a ) に示すように、ねじ孔 2 0、及び孔 3 , 2 2には補助部材 7が差し込まれる。 As shown in FIG. 2 (a), the auxiliary member 7 is inserted into the screw hole 20 and the holes 3 and 2 2.

[0058] 締結部材 5は、第 1の被接合部材 1に溶接などの手法により予め固着しておいてもよい。 The fastening member 5 may be secured in advance to the first member 1 to be joined by a technique such as welding.

[0059] 図 2 ( d ) に示すように、補助部材 7に由来する材料は、摩擦熱と塑性流動によって、締結部材 5のねじ孔 2 0内周面、及び第 1の被接合部材 1の孔 3内周面のそれぞれに密着し且つ第 2の被接合部材 2に同化するように形作られ、補助部材 7が第 1、第 2の被接合部材 1 , 2 1を接合している。 [0059] As shown in Fig. 2 (d), the material derived from the auxiliary member 7 is made of the screw hole 20 inner peripheral surface of the fastening member 5 and the first joined member 1 by frictional heat and plastic flow. Are formed in such a manner as to be in close contact with the inner peripheral surface of each of the holes 3 and assimilate to the second member 2 to be joined, and the auxiliary member 7 joins the first and second members 1 and 21 to each other. .

[0060] 補助部材 7を上述したような形状とする際には、裏当て部材 6と接合ツーゾレ 1 0を用いる。 [0061 ] 裏当て部材 6で保持されている補助部材 7の第 2の被接合部材 2 1側の端面に、接合ツール 1 0を回転させながら押し付けると、図 2 ( b ) に示すように、補助部材 7が摩擦熱と塑性流動により軟化する。 [0060] When the auxiliary member 7 has the shape as described above, the backing member 6 and the bonding tool 10 are used. [0061] When the welding tool 10 is rotated and pressed against the end surface of the second member 2 1 side of the auxiliary member 7 held by the backing member 6, as shown in FIG. 2 (b) The auxiliary member 7 is softened by frictional heat and plastic flow.

[0062] この後、図 2 ( c ) に示すように、補助部材 7に由来する材料が、ねじ孔[0062] After that, as shown in FIG. 2 (c), the material derived from the auxiliary member 7 is screw holes.

2 0のねじ溝に入り込み、第 2の被接合部材 2に同化する。 It enters the 20 screw groove and assimilates to the second member 2 to be joined.

[0063] 更に、図 2 ( d ) に示すように、接合ツール 1 0を補助部材 7から引き離して、第 2の被接合部材 2に同化した補助部材 7の塑性流動部位、及びねじ孔 2 0に密着した補助部材 7の塑性流動部位を硬化させると、第 1、第 2の被接合部材 1 , 2 1の接合が完了する。 [0063] Further, as shown in FIG. 2 (d), the welding tool 10 is pulled away from the auxiliary member 7, and the plastic flow site of the auxiliary member 7 assimilated to the second member 2 to be joined, and the screw hole When the plastic flow portion of the auxiliary member 7 that is in close contact with the 20 is hardened, the joining of the first and second joined members 1 and 21 is completed.

[0064] つまり、第 1の被接合部材 1の素材が、第 2の被接合部材 2 1 と同じアルミニゥム合金でも、あるいはアルミニウム合金以外の硬さや軟化温度などの物性が著しく違う異種材であっても、これらの部材 1 , 2 1を効率よく且つ確実に接合することができる。 That is, the material of the first member to be bonded 1 is the same aluminum alloy as that of the second member to be bonded 21, or is a dissimilar material having significantly different physical properties such as hardness and softening temperature other than the aluminum alloy. However, these members 1 and 21 can be joined efficiently and reliably.

[0065] また、第 1の被接合部材 1の素材が補助部材 7と同じアルミニウム合金であれば、補助部材 7に由来する材料が第 1の被接合部材 1に同化する。 Further, if the material of the first member 1 to be joined is the same aluminum alloy as the auxiliary member 7, the material derived from the auxiliary member 7 is assimilated to the first member 1 to be joined.

[0066] この他に、第 2の被接合部材 2 1に対して第 1の被接合部材 1が薄手である場合、第 1の被接合部材 1に締結部材 5を溶接などの手法で予め固着しておけば、締結部材 5によって補助部材 7に加わる剪断力が分散され、第 1、第 2の被接合部材 1 , 2 1に互いにずれる方向への力が働いても補助部材 7 が破断せず、第 1の被接合部材 1の剥離も防止できる。 In addition to this, when the first member 1 to be joined is thin with respect to the second member 21 to be joined, the fastening member 5 is welded to the first member 1 in advance by a technique such as welding. If fixed, the shearing force applied to the auxiliary member 7 is dispersed by the fastening member 5, and the auxiliary member 7 is broken even if forces in the direction deviating from each other are applied to the first and second bonded members 1 and 21. In addition, the first bonded member 1 can be prevented from peeling off.

[0067] 図 3は本発明の部材接合構造の第 3の例であり、図中、図 1 と同一の符号を付した部分は同一物を表している。 FIG. 3 shows a third example of the member joining structure of the present invention. In the figure, the parts denoted by the same reference numerals as those in FIG. 1 represent the same items.

[0068] この部材接合構造は、面接触するように重ねた板状の第 1、第 2の被接合部材 1 , 2と、第 2の被接合部材 2とは真反対に位置するように第 1の被接合部材 1に当接する締結部材 2 3と、補助部材 7とを備えている。 [0068] This member joining structure is configured so that the plate-like first and second joined members 1 and 2 stacked so as to be in surface contact with each other and the second joined member 2 are located in opposite positions. 1 is provided with a fastening member 2 3 that abuts the 1 member 1 and an auxiliary member 7.

[0069] 締結部材 2 3と補助部材 7はアルミニウム合金を素材とし、第 2の被接合部材 2は、アルミニウム合金よりも硬く且つ軟化温度が高い鋼を素材としている。 [0070] 締結部材 2 3には部材厚み方向に貫通する孔 2 4が、前記第 1、第 2の被接合部材 1 , 2の孔 3 , 4と同軸に位置するように穿設してある。 [0069] The fastening member 23 and the auxiliary member 7 are made of an aluminum alloy, and the second member 2 is made of steel that is harder and higher in softening temperature than the aluminum alloy. [0070] A hole 24 passing through the fastening member 23 in the thickness direction of the member is formed so as to be positioned coaxially with the holes 3 and 4 of the first and second members to be joined 1 and 2. .

[0071 ] 上記孔 2 4は、第 1の被接合部材 1側へ開口し且つ部材厚み方向へは貫通しない穴であってもよい。 [0071] The hole 24 may be a hole that opens toward the first bonded member 1 and does not penetrate in the thickness direction of the member.

[0072] 図 3 ( a ) に示すように、孔 2 4 , 3 , 4には補助部材 7が差し込まれる As shown in FIG. 3 (a), the auxiliary member 7 is inserted into the holes 2 4, 3, 4.

[0073] 締結部材 2 3は、第 1の被接合部材 1に溶接などの手法により予め固着しておいてもよい。 [0073] The fastening member 23 may be secured to the first member 1 to be joined in advance by a technique such as welding.

[0074] 図 3 ( d ) に示すように、補助部材 7に由来する材料は、摩擦熱と塑性流動によって、締結部材 2 3に同化し且つ第 1、 2の被接合部材 1 , 2の孔 3 , 4内周面のそれぞれに密着して当該第 2の被接合部材 2の孔 4の周囲を覆うように形作られ、補助部材 7が第 1、第 2の被接合部材 1 ' 2を接合している。 [0074] As shown in Fig. 3 (d), the material derived from the auxiliary member 7 is assimilated to the fastening member 23 by frictional heat and plastic flow, and the first and second members 1 and 2 are joined. The holes 3 and 4 are formed so as to be in close contact with the inner peripheral surfaces of the holes 2 and 4 so as to cover the periphery of the holes 4 of the second bonded member 2, and the auxiliary member 7 is the first and second bonded members 1 ′ 2 Are joined.

[0075] 補助部材 7を上述したような形状とする際には、裏当て部材 6と接合ツーゾレ 1 0を用いる。 [0075] When the auxiliary member 7 has the shape as described above, the backing member 6 and the bonding tool 10 are used.

[0076] 裏当て部材 6は、締結部材 2 3と補助部材 7を受ける役割をする。 [0076] The backing member 6 serves to receive the fastening member 23 and the auxiliary member 7.

[0077] 裏当て部材 6で保持されている補助部材 7の第 2の被接合部材 2側の端面に、接合ツール 1 0を回転させながら押し付けると、図 3 ( b ) に示すように、補助部材 7が摩擦熱と塑性流動により軟化する。 [0077] When the welding tool 10 is pressed against the end surface of the auxiliary member 7 held by the backing member 6 on the second member-to-be-joined 2 side, as shown in FIG. The member 7 is softened by frictional heat and plastic flow.

[0078] この後、図 3 ( c ) に示すように、補助部材 7に由来する材料が、締結部材 2 3に同化し、第 2の被接合部材 2の孔 4の周囲を覆う。 Thereafter, as shown in FIG. 3 (c), the material derived from the auxiliary member 7 is assimilated into the fastening member 23 and covers the periphery of the hole 4 of the second member 2 to be joined.

[0079] 更に、図 3 ( d ) に示すように、接合ツール 1 0を補助部材 7から引き離して、孔 4を覆う補助部材 7の塑性流動部位、及び締結部材 2 3に同化した補助部材 7の塑性流動部位を硬化させると、第 1、第 2の被接合部材 1 , 2 の接合が完了する。 Further, as shown in FIG. 3 (d), the joining tool 10 is pulled away from the auxiliary member 7, and the plastic flow site of the auxiliary member 7 covering the hole 4 and the auxiliary member assimilated into the fastening member 23. When the plastic flow site of the member 7 is cured, the joining of the first and second members 1 and 2 is completed.

[0080] つまり、第 1の被接合部材 1の素材が、第 2の被接合部材 2と同じ鋼でも、あるいは鋼以外の硬さや軟化温度などの物性が著しく違う異種材であっても、これらの部材 1 , 2を効率よく且つ確実に接合することができる。 [0081 ] また、第 1の被接合部材 1の素材が補助部材 7と同じアルミニウム合金であれば、補助部材 7に由来する材料が第 1の被接合部材 1に同化する。 [0080] That is, even if the material of the first member 1 to be joined is the same steel as the second member 2 or a different kind of material other than steel, such as hardness and softening temperature, which are significantly different. The members 1 and 2 can be joined efficiently and reliably. Further, if the material of the first member 1 to be joined is the same aluminum alloy as that of the auxiliary member 7, the material derived from the auxiliary member 7 is assimilated to the first member 1 to be joined.

[0082] この他に、第 2の被接合部材 2に対して第 1の被接合部材 1が薄手である場合、第 1の被接合部材 1に締結部材 2 3を溶接などの手法で予め固着しておけば、締結部材 2 3によって補助部材 7に加わる剪断力が分散され、第 1 、第 2の被接合部材 1 , 2に互いにずれる方向への力が働いても補助部材 7 が破断せず、第 1の被接合部材 1の剥離も防止できる。 In addition to this, when the first member 1 is thin with respect to the second member 2, the fastening member 23 is fixed to the first member 1 in advance by a technique such as welding. In this case, the shearing force applied to the auxiliary member 7 is dispersed by the fastening member 2 3, and the auxiliary member 7 is broken even if a force in a direction deviating from each other is applied to the first and second bonded members 1 and 2. In addition, the first bonded member 1 can be prevented from peeling off.

[0083] 図 4は本発明の部材接合構造の第 4の例であり、図中、図 2、図 3と同一の符号を付した部分は同一物を表している。 FIG. 4 shows a fourth example of the member joining structure of the present invention. In the figure, the same reference numerals as those in FIGS. 2 and 3 denote the same parts.

[0084] この部材接合構造は、面接触するように重ねた板状の第 1、第 2の被接合部材 1 , 2 1 と、第 2の被接合部材 2 1 とは真反対に位置するように第 1の被接合部材 1に当接する締結部材 2 3と、補助部材 7とを備えている。 [0084] This member joining structure is such that the plate-like first and second joined members 1 and 2 1 and the second joined member 2 1 that are stacked so as to be in surface contact with each other are positioned opposite to each other. In addition, a fastening member 23 that contacts the first member 1 to be joined and an auxiliary member 7 are provided.

[0085] 第 2の被接合部材 2 1 と締結部材 2 3と補助部材 7はアルミニウム合金を素材としている。 [0085] The second member 21, the fastening member 23, and the auxiliary member 7 are made of an aluminum alloy.
