Since the most protruding portion of the convex portion 9 is substantially flush with the outer surface of the bent portion 11, the first member 2 and the auxiliary member 4 are in an engaged state, and are opposite to the protruding direction of the convex portion 9. When the first member 2 is viewed from the direction, the end face of the welded portion 7 is exposed. Therefore, at the time of welding the second member 3 and the auxiliary member 4, the second member 3 and the end surface of the welded portion 7 of the auxiliary member 4 are easily brought into contact with each other, and the welding operation is facilitated.

第1部材2と補助部材4との係合は、延在部10と折曲部11とが第1部材2の縁部5から貫通孔6までを挟持することにより達成されている。更に、第1部材2と補助部材4との係合時に、補助部材4の凸部9が貫通孔6に挿入されていることによって、凸部9が補助部材4の抜け止め部材として機能するので、第1部材2と補助部材4との安定的な係合状態を実現する。   The engagement between the first member 2 and the auxiliary member 4 is achieved by the extending portion 10 and the bent portion 11 sandwiching from the edge 5 to the through hole 6 of the first member 2. Furthermore, when the first member 2 and the auxiliary member 4 are engaged, the convex portion 9 of the auxiliary member 4 is inserted into the through hole 6, so that the convex portion 9 functions as a retaining member for the auxiliary member 4. The stable engagement state between the first member 2 and the auxiliary member 4 is realized.

補助部材4の凸部9の最も突出する部位と第2部材3とが、溶接によって生じる溶着界面Sにおいて溶着している。溶着界面Sにおける第2部材3と補助部材4との溶接強度は、第2部材3及び補助部材4の材料及び、後述の異材接合方法における溶接工程の溶接条件によって調整可能である。   The most protruding portion of the convex portion 9 of the auxiliary member 4 and the second member 3 are welded at the welding interface S generated by welding. The welding strength between the second member 3 and the auxiliary member 4 at the welding interface S can be adjusted by the material of the second member 3 and the auxiliary member 4 and the welding conditions in the welding process in the dissimilar material joining method described later.

(4)各部材の材料
ここで、第1部材2、第2部材3及び補助部材4の各材料について説明する。
第1部材2の材料である第1材料と、第2部材3の材料である第2材料とは、溶接が困難な材料の組合せ、又は、溶接しても例えば車両用部品として使用に耐え得る溶接強度を得ることが困難な材料の組合せである。第1材料及び第2材料の組合せとしては、例えば一方がアルミニウム又はアルミニウム系材料であり、他方が鉄又は鉄系材料である組合せ等を採用することができる。
補助部材4の材料である第3材料は、第2材料に溶接可能な材料、好ましくは車両用部品としての使用に耐え得る溶接強度を以って第2材料に溶接可能な材料である。第3材料は、第2材料が決定されると、第2材料に応じて適当な材料が決定される。
本発明に係る異材接合体を車両用部品として用いる場合、第1材料、第2材料及び第3材料の組合せとして好ましいのは、第1材料がアルミニウム又はアルミニウム系材料であり、第2材料及び第3材料が鉄又は鉄系材料である。
(4) Material of each member Here, each material of the 1st member 2, the 2nd member 3, and the auxiliary member 4 is demonstrated.
The first material that is the material of the first member 2 and the second material that is the material of the second member 3 can be combined with materials that are difficult to weld, or can be used as, for example, a vehicle component even if they are welded. It is a combination of materials for which it is difficult to obtain weld strength. As a combination of the first material and the second material, for example, a combination in which one is aluminum or an aluminum-based material and the other is iron or an iron-based material can be employed.
The third material as the material of the auxiliary member 4 is a material that can be welded to the second material, preferably a material that can be welded to the second material with a welding strength that can withstand use as a vehicle component. As the third material, when the second material is determined, an appropriate material is determined according to the second material.
When the dissimilar material joined body according to the present invention is used as a vehicle component, it is preferable that the first material is aluminum or an aluminum-based material as a combination of the first material, the second material, and the third material. The three materials are iron or iron-based materials.

(5)異材接合方法
ここで、図5及び図6を参照しつつ、本発明に係る異材接合方法の一実施形態について説明する。図5及び図6には、図4で示した部材と同一部材を示しているので、各部材には同一の参照符号を付すこととする。また、各部材の詳細な説明は省略する。
図5には、本発明に係る異材接合方法における係合工程の一実施形態を示した。また、図6には、本発明に係る異材接合方法における溶接工程の一実施形態を示した。
(5) Dissimilar Material Joining Method Here, an embodiment of the dissimilar material joining method according to the present invention will be described with reference to FIGS. 5 and 6. 5 and 6 show the same members as those shown in FIG. 4, and therefore, the same reference numerals are assigned to the respective members. Detailed description of each member is omitted.
In FIG. 5, one Embodiment of the engagement process in the different material joining method which concerns on this invention was shown. FIG. 6 shows an embodiment of a welding process in the dissimilar material joining method according to the present invention.

図5(A)に示すように、先ず縁部5近傍に貫通孔6を形成して成る第1部材2を用意する。図5に示す係合工程においては、第1部材2は適宜のクランプ等によって固定されていると、補助部材4を第1部材2に係合させ易くなることにより、係合工程における作業効率が向上するので好ましい。
続いて図5(B)に示すように、補助部材4が白抜き矢印で示した方向に第1部材2の縁部5から差し込まれる。補助部材4における係合部8の延在部10と折曲部11との距離、つまり延在部10と折曲部11とが変形せずに挟持することのできる部材の厚みは、第1部材2の厚みより若干小さく形成されている。なお、延在部10と折曲部11との距離が、第1部材2の厚みより若干小さいと、係合部8が第1部材2を挟持することができるので、凸部9を形成していなくとも第1部材2と補助部材4との係合を達成可能である。延在部10と折曲部11との距離と、第1部材2の厚みとの差は、補助部材4を第1部材2の縁部5から差し込む作業には大きな力を必要としない程度となるように調整されるのが良い。
次に図5(C)に示すように、延在部10と折曲部11とが離れる方向に補助部材4を変形させ、凸部9を第1部材2の縁部5から貫通孔6まで摺動させる。
上記凸部9による第1部材2上の摺動は、凸部9が貫通孔6に達した時に、凸部9が貫通孔6内に挿入されることとなって、完了する。凸部9による第1部材2上の摺動が完了した状態を、図5(D)に示した。凸部9が貫通孔6内に挿入されることによって、補助部材4の延在部10と折曲部11とが離れる方向への変形は、解除される。図5(D)に示す状態を以って、異材接合方法における係合工程は完了されたことになる。
As shown in FIG. 5A, first, a first member 2 formed with a through hole 6 in the vicinity of the edge 5 is prepared. In the engagement process shown in FIG. 5, if the first member 2 is fixed by an appropriate clamp or the like, the auxiliary member 4 can be easily engaged with the first member 2. Since it improves, it is preferable.
Subsequently, as shown in FIG. 5B, the auxiliary member 4 is inserted from the edge 5 of the first member 2 in the direction indicated by the white arrow. The distance between the extended portion 10 and the bent portion 11 of the engaging portion 8 in the auxiliary member 4, that is, the thickness of the member that can be sandwiched without the extended portion 10 and the bent portion 11 being deformed is the first. It is formed slightly smaller than the thickness of the member 2. If the distance between the extending portion 10 and the bent portion 11 is slightly smaller than the thickness of the first member 2, the engaging portion 8 can sandwich the first member 2, so that the convex portion 9 is formed. Even if not, the engagement between the first member 2 and the auxiliary member 4 can be achieved. The difference between the distance between the extending portion 10 and the bent portion 11 and the thickness of the first member 2 is such that a large force is not required for the operation of inserting the auxiliary member 4 from the edge portion 5 of the first member 2. It is good to adjust so that it becomes.
Next, as shown in FIG. 5C, the auxiliary member 4 is deformed in a direction in which the extending portion 10 and the bent portion 11 are separated from each other, and the convex portion 9 is moved from the edge portion 5 of the first member 2 to the through hole 6. Slide.
The sliding on the first member 2 by the convex portion 9 is completed when the convex portion 9 is inserted into the through hole 6 when the convex portion 9 reaches the through hole 6. FIG. 5D shows a state where sliding on the first member 2 by the convex portion 9 is completed. By inserting the convex portion 9 into the through hole 6, the deformation of the auxiliary member 4 in the direction in which the extending portion 10 and the bent portion 11 are separated is released. With the state shown in FIG. 5D, the engaging step in the dissimilar material joining method is completed.

続いて図6に示す溶接工程が実行される。本実施形態においては図3に示した車両用部品を溶接する車体溶接工程S2で用いられることの多い、スポット溶接を採用している。
先ず図6(A)に示すように、補助部材4が係合して成る第1部材2と、補助部材4の溶着部7を当接させた第2部材3とを位置決めする。該位置決めは、第2部材3の溶接箇所が補助部材4の溶着部7が当接する位置となるように設定される。
図6(B)に示すように、補助部材4の凸部9内に挿入される電極E1の先端部を溶着部に圧接する。また、電極E1と軸線を略一致させて配置される電極E2の先端部を第2部材3に圧接する。電極E1の圧接方向は第1部材2から第2部材3に向かう方向であり、電極E2の圧接方向は第2部材3から第1部材2に向かう方向である。更に、電極E1及びE2に電流を流すことによって、電極E1及びE2の各圧接部位の間の金属を溶接する。
図6(C)に示すように、スポット溶接によって、第2部材3と補助部材4の溶着部7とが、その間に溶着界面Sが形成されて溶着している。図6(C)に示す状態を持って、異材接合方法における溶接工程は完了されたことになる。
凸部9は、第1部材2から第2部材3に向かって貫通孔6内に挿入されている。仮に、補助部材4の第1部材2に対する差し込み方向とは逆方向、つまり図6(C)における右方向に、第2部材3及び補助部材4が移動しようとしても、凸部9が抜け止め部材として機能するので、第2部材3及び補助部材4は移動することができない。具体的には、凸部9が貫通孔6の内周面に当接するので、第2部材3及び補助部材4が図6(C)における右方向に移動することはできない。
第1部材2と、第2部材3に溶着している補助部材4とは係合しているので、結果として、第1部材2と、第1部材2とは溶接が困難又は良好な溶接強度を確保し難い材料を含む第2部材3とが接合されたことになる。
Then, the welding process shown in FIG. 6 is performed. In the present embodiment, spot welding, which is often used in the vehicle body welding step S2 for welding the vehicle parts shown in FIG. 3, is employed.
First, as shown in FIG. 6A, the first member 2 formed by the engagement of the auxiliary member 4 and the second member 3 with which the welding portion 7 of the auxiliary member 4 is brought into contact are positioned. The positioning is set so that the welding location of the second member 3 is a position where the welded portion 7 of the auxiliary member 4 abuts.
As shown in FIG. 6B, the tip of the electrode E1 inserted into the convex portion 9 of the auxiliary member 4 is pressed against the welded portion. In addition, the tip end of the electrode E <b> 2 that is arranged so that the axis line of the electrode E <b> 1 is substantially coincided with the electrode E <b> 1 is pressed against the second member 3. The pressure contact direction of the electrode E1 is a direction from the first member 2 toward the second member 3, and the pressure contact direction of the electrode E2 is a direction from the second member 3 toward the first member 2. Furthermore, the metal between each press-contact part of the electrodes E1 and E2 is welded by sending an electric current through the electrodes E1 and E2.
As shown in FIG. 6C, the welding interface 7 is formed between the second member 3 and the welded portion 7 of the auxiliary member 4 by spot welding. With the state shown in FIG. 6C, the welding process in the dissimilar material joining method is completed.
The convex portion 9 is inserted into the through hole 6 from the first member 2 toward the second member 3. Even if the second member 3 and the auxiliary member 4 try to move in the direction opposite to the insertion direction of the auxiliary member 4 with respect to the first member 2, that is, in the right direction in FIG. Therefore, the second member 3 and the auxiliary member 4 cannot move. Specifically, since the convex portion 9 contacts the inner peripheral surface of the through hole 6, the second member 3 and the auxiliary member 4 cannot move in the right direction in FIG.
Since the first member 2 and the auxiliary member 4 welded to the second member 3 are engaged, as a result, the first member 2 and the first member 2 are difficult to weld or have good welding strength. The second member 3 containing a material that is difficult to secure is joined.

例えば、鋼板に対してアルミニウム板を直接溶接しようとすると、溶接強度の低下を招き易い金属間化合物が形成してしまうことが多い。しかしながら、本発明に係る異材接合方法の一実施形態においては、第2部材3と、第1部材2に係合してなる補助部材4とを溶接することにより、溶接強度の低下を生じ得る金属間化合物が形成する材料同士の溶接は行わないので、異種の材料を含む第1部材2と第2部材3とを容易に接合可能である。
また、溶接工程の前に実行される係合工程では、補助部材4を第1部材2の縁部5から差し込んで係合させるだけであるので、容易に実行可能であり、車両用部品の製造工程を大幅に変更する必要が無い。例えば、図3に示した部品プレス成形工程S1と車体溶接工程S2との間に、作業者が特別な機器を用いることなく、手で補助部材4を把持して第1部材2に差し込むだけで、係合工程を実行することができる。
補助部材4は挟持及び凸部9の貫通孔6内への挿入によって第1部材2に対して係合しているので、溶接工程までに衝撃、振動、傾斜等が第1部材2に作用したとしても、補助部材4が第1部材2から脱離することは無い又は脱離し難い。よって、溶接工程において溶接箇所と成る補助部材4の取付位置がずれないので、溶接箇所がずれてしまうことも無い又は起き難い。
補助部材4の大きさは、第1部材2に係合させても第1部材2全体を被覆せず、第1部材2の縁部5から貫通孔6までの領域に取付けられる程度であるので、例えば車両用部品の製造工程において他の作業及び他の部品の取付け等を妨げることはない。
第1部材2に係合させた補助部材4は溶接時においてもその一部が露出しているので、作業者が溶接箇所を視認により判別し易い。
以上により、異種の材料を含む部材を接合することのできる異材接合方法は、例えば従来の車両用部品の製造工程に対して煩雑な別工程を付加する必要が無く、係合工程も容易に実行可能であり、溶接箇所がずれない又はずれ難く、他の作業及び他の部品の取付け等を妨げず、溶接箇所が判別し易いので、作業効率が高い。
For example, when an aluminum plate is directly welded to a steel plate, an intermetallic compound that tends to cause a decrease in welding strength is often formed. However, in one embodiment of the dissimilar material joining method according to the present invention, a metal that can cause a decrease in welding strength by welding the second member 3 and the auxiliary member 4 engaged with the first member 2. Since the materials formed by the intermetallic compound are not welded together, the first member 2 and the second member 3 containing different materials can be easily joined.
Moreover, in the engagement process performed before a welding process, since the auxiliary member 4 is only inserted and engaged from the edge 5 of the 1st member 2, it can carry out easily and manufacture of vehicle components. There is no need to change the process significantly. For example, between the component press molding step S1 and the vehicle body welding step S2 shown in FIG. 3, the operator simply holds the auxiliary member 4 by hand and inserts it into the first member 2 without using any special equipment. The engagement step can be executed.
Since the auxiliary member 4 is engaged with the first member 2 by clamping and inserting the convex portion 9 into the through hole 6, impact, vibration, inclination, etc. acted on the first member 2 by the welding process. However, the auxiliary member 4 does not detach from the first member 2 or is difficult to detach. Therefore, since the attachment position of the auxiliary member 4 serving as a welding location does not shift in the welding process, the welding location does not shift or hardly occurs.
Since the size of the auxiliary member 4 does not cover the entire first member 2 even when engaged with the first member 2, the auxiliary member 4 can be attached to the region from the edge 5 to the through hole 6 of the first member 2. For example, it does not interfere with other operations and attachment of other parts in the manufacturing process of the vehicle parts.
Since a part of the auxiliary member 4 engaged with the first member 2 is exposed even during welding, it is easy for the operator to determine the welding location by visual recognition.
As described above, the dissimilar material joining method capable of joining members containing different kinds of materials does not require a complicated separate process, for example, with respect to the conventional manufacturing process for vehicle parts, and the engagement process is also easily performed. It is possible, the welding location does not shift or is difficult to shift, and does not interfere with other work and the mounting of other parts, and the welding location is easy to distinguish, so the work efficiency is high.

本発明に係る異材接合方法においては、第1材料としてアルミニウム又はアルミニウム系材料を用いる場合、第1部材に予め貫通孔を設けておく必要は無い。溶接工程においてスポット溶接を用いるのであれば、貫通孔を設けることなく補助部材を係合させた第1部材は、スポット溶接で生じる抵抗熱で溶融するので、溶接工程が完了した時には結果として貫通孔が形成されることになる。   In the dissimilar material joining method according to the present invention, when aluminum or an aluminum-based material is used as the first material, it is not necessary to previously provide a through hole in the first member. If spot welding is used in the welding process, the first member engaged with the auxiliary member without providing a through hole is melted by resistance heat generated by spot welding. Will be formed.

図5及び図6に示すように、補助部材4の溶着部7は、第1部材2の貫通孔6に向かう方向でかつ第1部材2から第2部材3に向かう方向に突出する凸部9の、最も突出する部位である。溶着部7は、係合工程に供される前から予め凸形状に形成された凸部9を有している。
本発明に係る異材接合体において補助部材の溶着部が凸部を有する場合、凸部の形成は例えば次の実施形態を挙げることができる。例えば凸部形成に係る一実施形態として、上記溶着部7の凸部9のように、本発明に係る異材接合方法における係合工程に供される前から予め凸形状の凸部が補助部材に形成されている実施形態を挙げることができる。更に、凸部形成に係る他の実施形態として、係合工程及び溶接工程の前には溶着部と成る部位が平板形状を成し、溶接時にスポット溶接等で電極が圧接されて局所的に作用する圧力によって貫通孔内に平板状の補助部材の一部が押し込まれて、結果として凸部が形成される実施形態を挙げることができる。
本発明に係る異材接合方法及び異材接合体において、凸部形成に係る実施形態としては溶着部における良好な溶接強度が確保できる限り、特に制限されない。なお、係合工程に供される前に予め凸部を補助部材に形成しておく実施形態を採用すると、係合工程において凸部が貫通孔内に挿入されることにより、第1部材と補助部材との安定的な係合状態を実現可能である。第1部材と補助部材とが安定的に係合していると、係合工程の完了後に溶接工程に供する際、第1部材に振動、衝撃、及び傾斜等が作用しても、第1部材に一旦係合させた補助部材が脱離し難いので、好ましい。
As shown in FIGS. 5 and 6, the welded portion 7 of the auxiliary member 4 is a convex portion 9 that protrudes in a direction toward the through hole 6 of the first member 2 and in a direction toward the second member 3 from the first member 2. This is the most protruding part. The welding part 7 has the convex part 9 previously formed in the convex shape before being used for an engagement process.
In the dissimilar material joined body according to the present invention, when the welded portion of the auxiliary member has a convex portion, the formation of the convex portion can include, for example, the following embodiment. For example, as one embodiment relating to the formation of the convex portion, like the convex portion 9 of the welded portion 7, the convex convex portion is previously used as the auxiliary member before being subjected to the engaging step in the dissimilar material joining method according to the present invention. Mention may be made of the embodiment being formed. Furthermore, as another embodiment relating to the formation of the convex portion, the portion that becomes the welded portion has a flat plate shape before the engaging step and the welding step, and the electrode is pressed by spot welding or the like during welding to act locally. There may be mentioned an embodiment in which a part of the flat auxiliary member is pushed into the through hole by the pressure to be formed, and as a result, a convex portion is formed.
In the dissimilar material joining method and dissimilar material joined body according to the present invention, the embodiment relating to the formation of the convex portion is not particularly limited as long as good welding strength at the welded portion can be secured. In addition, if the embodiment in which the convex portion is formed in the auxiliary member in advance before being used in the engaging step is adopted, the first member and the auxiliary member are inserted by inserting the convex portion into the through hole in the engaging step. A stable engagement state with the member can be realized. When the first member and the auxiliary member are stably engaged, even if vibration, impact, inclination, or the like acts on the first member when the welding process is performed after the engagement process is completed, the first member It is preferable because the auxiliary member once engaged with is difficult to be detached.

本発明に係る異材接合体において、補助部材の凸部の突出方向は、第1部材の貫通孔に向かう方向でかつ第2部材から第1部材に向かう方向であっても良い。すなわち、例えば、前記溶接用開口部12を設けることなく、図4における下から上に向かう方向に突出する凸部が形成されていても良い。   In the dissimilar material joined body according to the present invention, the protruding direction of the convex portion of the auxiliary member may be a direction toward the through hole of the first member and a direction from the second member toward the first member. That is, for example, without providing the welding opening 12, a protrusion protruding in the direction from the bottom to the top in FIG. 4 may be formed.

(7)変形例
ここで、本発明に係る異材接合体における第1部材及び補助部材の変形例を、図面を参照しつつ説明する。

図7には、第1部材の変形例を示している。
(7) Modified Example Here, modified examples of the first member and the auxiliary member in the dissimilar material joined body according to the present invention will be described with reference to the drawings.
(7-1) Modified Example of First Member FIG. 7 shows a modified example of the first member.

図7(A)に示す第1部材2は、図4〜図6に示した前記第1部材2と同一部材である。第1部材2は、縁部5近傍に貫通孔6を有している。   The first member 2 shown in FIG. 7A is the same member as the first member 2 shown in FIGS. The first member 2 has a through hole 6 in the vicinity of the edge 5.

図7(B)に示す第1部材21は、その一部が折曲されて複数の板部が重ねられて成る重複部13を有している。第1部材21は、平板形状を成す上板部211の一部が約180°程度一回折曲されて、下板部212が形成されている。上板部211と下板部212とが重ねられて重複部13が形成されている。第1部材21は、下板部13の縁部51近傍に貫通孔61を有している。   The first member 21 shown in FIG. 7B has an overlapping portion 13 in which a part thereof is bent and a plurality of plate portions are stacked. In the first member 21, a part of an upper plate portion 211 having a flat plate shape is bent once by about 180 ° to form a lower plate portion 212. The upper plate portion 211 and the lower plate portion 212 are overlapped to form the overlapping portion 13. The first member 21 has a through hole 61 in the vicinity of the edge portion 51 of the lower plate portion 13.

図7(C)及び(D)に示す第1部材22及び23は、いずれもスリット141及び142を有している。   The first members 22 and 23 shown in FIGS. 7C and 7D both have slits 141 and 142.

図7(C)に示す第1部材22は、平板形状を成す基板部15の縁部52近傍から、縁部52及び基板部15に直交又は略直交する2つの面が対向して立ち上がる***部16と、2つの***部16及び16の上端部に架け渡される板体である天板部17と、を有している。天板部17の縁部側端辺部及びその反対側の端辺部と、基板部15と、2つの***部16及び16との間に2つのスリット141及び141がそれぞれ形成されている。第1部材22は貫通孔を有していないが、天板部17における***部16の立ち上がり方向とは逆側、つまり図7(C)における天板部17の下側には何の部材も設けられていないので、第1部材22は実質的に貫通孔を有していることと同じである。   The first member 22 shown in FIG. 7C is a raised portion in which two surfaces perpendicular to or substantially perpendicular to the edge portion 52 and the substrate portion 15 are raised from the vicinity of the edge portion 52 of the substrate portion 15 having a flat plate shape. 16, and a top plate portion 17 that is a plate body spanning the upper end portions of the two raised portions 16 and 16. Two slits 141 and 141 are formed between the edge portion side edge portion of the top plate portion 17 and the opposite edge portion thereof, the substrate portion 15, and the two raised portions 16 and 16, respectively. The first member 22 does not have a through-hole, but there is no member on the side opposite to the rising direction of the raised portion 16 in the top plate portion 17, that is, below the top plate portion 17 in FIG. Since it is not provided, the first member 22 is substantially the same as having a through hole.

図7(D)に示す第1部材23は、縁部53に平行又は略平行なスリット142を有している。第1部材23は貫通孔を有していないが、図7(D)における第1部材23の裏側には何の部材も設けられていないので、第1部材23は実質的に貫通孔を有していることと同じである。   The first member 23 shown in FIG. 7D has a slit 142 that is parallel or substantially parallel to the edge 53. Although the first member 23 does not have a through-hole, since no member is provided on the back side of the first member 23 in FIG. 7D, the first member 23 substantially has a through-hole. Is the same as

本発明に係る異材接合体は、第1部材の形状に応じて、第1部材に係合する補助部材の形状も変更することができる。以下に、図7に示した第1部材2、21、22及び23に対して係合可能な補助部材の実施形態を示す。   In the dissimilar material joined body according to the present invention, the shape of the auxiliary member engaged with the first member can be changed according to the shape of the first member. Hereinafter, embodiments of auxiliary members that can be engaged with the first members 2, 21, 22, and 23 shown in FIG. 7 will be described.

図8(A)に示す補助部材41において、図4に示した補助部材4との相違点は、平面視矩形の凸部91を有し、延在部101が折曲されて折曲部111と成る部位が曲面で形成されている点である。該相違点以外については、補助部材4と同様であり、詳細な説明は省略する。
延在部101が折曲されて折曲部111と成る部位が曲面で形成されていると、本発明に係る異材接合方法の係合工程において、作業者が補助部材41の端部である該曲面を把持し易いので、作業効率が向上する。
The auxiliary member 41 shown in FIG. 8A is different from the auxiliary member 4 shown in FIG. 4 in that it has a convex portion 91 having a rectangular shape in plan view, and the extended portion 101 is bent to be a bent portion 111. This is the point where the part is formed with a curved surface. Except for the difference, the auxiliary member 4 is the same as the auxiliary member 4 and will not be described in detail.
When the extending portion 101 is bent and the portion that becomes the bent portion 111 is formed with a curved surface, the worker is the end of the auxiliary member 41 in the engaging step of the dissimilar material joining method according to the present invention. Since it is easy to grip the curved surface, work efficiency is improved.

図8(B)に示す補助部材42において、前記補助部材4との相違点は、延在部102が折曲されて折曲部112と成る部位が曲面で形成されている点と、折曲部112が小さい点である。該相違点以外については、補助部材4と同様であり詳細な説明は省略する。
折曲部112が小さいとは、具体的には係合工程を実行するときに補助部材42の差し込み方向に沿った折曲部112が短く形成されており、凸部92に臨む程度にまでは折曲部112を設けていないことである。
延在部102が折曲されて折曲部112と成る部位が曲面で形成されていると、本発明に係る異材接合方法の係合工程において、作業者が補助部材42の端部である該曲面を把持し易いので、作業効率が向上する。
また、折曲部112が他の実施形態よりも小さく形成されているので、部材製造に要する材料の削減、補助部材42の設置領域の縮小等を図ることができる。
補助部材42を採用する場合、第1部材2における貫通孔6から縁部5までの大きさと、溶着部72から延在部102の端部までの大きさとを同一にするのが好ましい。これにより、係合工程が完了すれば、係合部82における延在部102及び折曲部112の共通端部である曲面部分の内側に縁部5が当接し、凸部92が貫通孔6内に挿入されることで、第1部材2と補助部材42とがガタつきなく係合する。したがって、補助部材42は、延在部102及び折曲部112により第1部材2を挟持はしないが、第1部材2の貫通孔6及び縁部5に引っ掛けた状態と成るので、安定的な係合状態を実現可能である。
In the auxiliary member 42 shown in FIG. 8 (B), the difference from the auxiliary member 4 is that the extension portion 102 is bent and the bent portion 112 is formed as a curved surface. The part 112 is a small point. Except this difference, it is the same as that of the auxiliary member 4, and detailed description is abbreviate | omitted.
Specifically, the small bent portion 112 means that the bent portion 112 along the insertion direction of the auxiliary member 42 is formed short when the engaging step is executed, and the bent portion 112 faces the convex portion 92. That is, the bent portion 112 is not provided.
When the extended portion 102 is bent and the portion that becomes the bent portion 112 is formed with a curved surface, the worker is the end of the auxiliary member 42 in the engaging step of the dissimilar material joining method according to the present invention. Since it is easy to grip the curved surface, work efficiency is improved.
In addition, since the bent portion 112 is formed smaller than in the other embodiments, it is possible to reduce the material required for manufacturing the member, reduce the installation area of the auxiliary member 42, and the like.
When the auxiliary member 42 is employed, it is preferable that the size from the through hole 6 to the edge portion 5 in the first member 2 is the same as the size from the welded portion 72 to the end portion of the extending portion 102. Thus, when the engaging step is completed, the edge portion 5 comes into contact with the inside of the curved surface portion that is the common end portion of the extending portion 102 and the bent portion 112 in the engaging portion 82, and the convex portion 92 is formed in the through hole 6. By being inserted into the first member 2, the first member 2 and the auxiliary member 42 are engaged with each other without rattling. Therefore, the auxiliary member 42 does not sandwich the first member 2 by the extending portion 102 and the bent portion 112, but is in a state of being hooked on the through hole 6 and the edge portion 5 of the first member 2. The engaged state can be realized.

図8(C)に示す補助部材43において、前記補助部材4との相違点は、係合工程を実行するときの補助部材43の差込み方向に沿って凸部93近傍に切り込みを入れ、延在部103の端部近傍で繋がって成る短冊状でかつ該差し込み方向に沿った折曲部113を形成している点である。
補助部材43を製造する際に、折曲部113の形成は、延在部103の端部を約180°折曲する必要は無く、切り込みを入れて第1部材2の厚み方向に若干折曲すれば良い。よって、部材の製造工程を簡素化することができる。
In the auxiliary member 43 shown in FIG. 8C, the difference from the auxiliary member 4 is that a cut is made in the vicinity of the convex portion 93 along the insertion direction of the auxiliary member 43 when the engaging step is executed. It is a point that a bent portion 113 is formed in a strip shape connected in the vicinity of the end portion of the portion 103 and along the insertion direction.
When manufacturing the auxiliary member 43, it is not necessary to bend the end portion of the extended portion 103 by about 180 °, and the bent portion 113 is slightly bent in the thickness direction of the first member 2 by cutting. Just do it. Therefore, the manufacturing process of a member can be simplified.

図9には、図7(B)に示した第1部材21に対して係合可能な補助部材44を示している。
補助部材44は、図4に示した補助部材4のように係合部を有しておらず、凸部94を有する溶着部74と、差込規制部181とを備える。差込規制部181は、係合工程を実行するときの補助部材44の差込み方向に直交又は略直交する板状部材である。差込規制部181が設けられる位置は、貫通孔61内に凸部94が挿入された時に縁部51に差込規制部181が当接する位置に設定される。
第1部材21と補助部材44との係合は、補助部材44を白抜き矢印の方向に差込むことにより達成される。補助部材44の差込み動作によって、溶着部74が貫通孔61の少なくとも一部を覆い、重複部13における貫通孔61が形成される下板部212と、下板部212に隣接する上板部211とに補助部材44が挟持される。
差込規制部181を設けることによって、第1部材21に対して補助部材44を係合させた時に、貫通孔61内に凸部94が挿入される位置よりも更なる差込みが不能となる。第1部材21に対する必要以上の補助部材44の差込みを規制することにより、貫通孔61内に一旦挿入された凸部94が、不要な差込み動作によって貫通孔61外へずれてしまうことを防止可能である。
FIG. 9 shows an auxiliary member 44 that can be engaged with the first member 21 shown in FIG.
The auxiliary member 44 does not have an engaging portion like the auxiliary member 4 shown in FIG. 4, and includes a welding portion 74 having a convex portion 94 and an insertion restricting portion 181. The insertion restricting portion 181 is a plate-like member that is orthogonal or substantially orthogonal to the insertion direction of the auxiliary member 44 when executing the engagement step. The position where the insertion restricting portion 181 is provided is set to a position where the insertion restricting portion 181 contacts the edge 51 when the convex portion 94 is inserted into the through hole 61.
The engagement between the first member 21 and the auxiliary member 44 is achieved by inserting the auxiliary member 44 in the direction of the white arrow. By the insertion operation of the auxiliary member 44, the welded portion 74 covers at least a part of the through hole 61, the lower plate portion 212 in which the through hole 61 in the overlapping portion 13 is formed, and the upper plate portion 211 adjacent to the lower plate portion 212. The auxiliary member 44 is held between the two.
By providing the insertion restricting portion 181, when the auxiliary member 44 is engaged with the first member 21, further insertion becomes impossible from the position where the convex portion 94 is inserted into the through hole 61. By restricting the insertion of the auxiliary member 44 more than necessary into the first member 21, it is possible to prevent the convex portion 94 once inserted into the through hole 61 from being displaced outside the through hole 61 due to an unnecessary insertion operation. It is.

図10には、図7(C)に示した第1部材22に対して係合可能な補助部材45、46、47、48及び49を示している。   FIG. 10 shows auxiliary members 45, 46, 47, 48, and 49 that can be engaged with the first member 22 shown in FIG. 7C.

図10(A)に示す補助部材45は、差込規制部182と挿通部19とを有する。
差込規制部182及び挿通部19は、係合工程を実行するときの補助部材45の差込み方向に直交又は略直交して折曲されて成る板状部材である。挿通部19は、溶接工程に供された時に溶着部と成る部位である。
挿通部19は、補助部材45の差込み方向手前側及び奥側にそれぞれ形成される2つのスリット141及び141を挿通する。2つのスリット141及び141を挿通部19が挿通した時に差込規制部182が縁部52近傍における***部16の端部及び天板部17の端部に当接することによって、挿通部19のスリット141への挿通動作、つまり補助部材45の差し込み動作が規制される。
***部16の高さを調整することによってスリット141の高さを挿通部19の厚みに合わせ、挿通部19を2つのスリット141及び141に挿通することにより、容易には抜けなくなるので、補助部材45の第1部材22に対する係合が達成される。
補助部材45は板状部材を一回折曲するだけで製造可能であることにより、部品製造に係る工程数が少ないので好ましい。
The auxiliary member 45 shown in FIG. 10A has an insertion restricting portion 182 and an insertion portion 19.
The insertion restricting portion 182 and the insertion portion 19 are plate-like members that are bent orthogonally or substantially orthogonally to the insertion direction of the auxiliary member 45 when performing the engaging step. The insertion part 19 is a part which becomes a welding part when it is subjected to a welding process.
The insertion part 19 inserts two slits 141 and 141 formed on the front side and the back side of the auxiliary member 45 in the insertion direction. When the insertion part 19 is inserted through the two slits 141 and 141, the insertion restricting part 182 abuts against the end part of the raised part 16 and the end part of the top plate part 17 in the vicinity of the edge part 52, thereby the slit of the insertion part 19. The insertion operation to 141, that is, the insertion operation of the auxiliary member 45 is restricted.
Since the height of the slit 141 is adjusted to the thickness of the insertion portion 19 by adjusting the height of the raised portion 16, and the insertion portion 19 is inserted into the two slits 141 and 141, the auxiliary member cannot be easily removed. 45 engagement with the first member 22 is achieved.
The auxiliary member 45 is preferable because it can be manufactured only by bending the plate-like member once, so that the number of steps involved in component manufacture is small.

図10(B)に示す補助部材46は、差込規制部182と挿通部19と枠状係合部201とを有する。なお、差込規制部182及び挿通部19は、補助部材45の差込規制部182及び挿通部19と同様の部材である。
枠状係合部201は、挿通部19を囲繞する枠状部材である。挿通部19を2つのスリット141及び141を挿通する際には、枠状係合部201を上方に一旦変位させ、挿通部19の先端が2つのスリット141及び141を挿通した上で、枠状係合部201を下方に変位させて初期位置に戻す。これにより、枠状係合部201が、挿通部19だけでなく、***部16及びスリット141も囲繞することになるので、第1部材22に対する補助部材46の係合状態が実現する。
枠状係合部201がスリット141及びその近傍の部材に一旦係合すると、高い係合強度を得られるので、第1部材22及び補助部材46が溶接工程に供される際に大きな振動、衝撃又は傾斜等が作用しても補助部材46の位置がずれない又はずれ難い。したがって、一旦位置決めした溶接箇所がずれない又はずれ難いこととなるので、溶接工程の作業効率が向上する。
The auxiliary member 46 shown in FIG. 10B has an insertion restricting portion 182, an insertion portion 19, and a frame-like engagement portion 201. The insertion restriction part 182 and the insertion part 19 are the same members as the insertion restriction part 182 and the insertion part 19 of the auxiliary member 45.
The frame-like engagement portion 201 is a frame-like member that surrounds the insertion portion 19. When inserting the two slits 141 and 141 through the insertion part 19, the frame-shaped engagement part 201 is temporarily displaced upward, and the tip of the insertion part 19 passes through the two slits 141 and 141, The engaging portion 201 is displaced downward to return to the initial position. As a result, the frame-shaped engaging portion 201 surrounds not only the insertion portion 19 but also the raised portion 16 and the slit 141, so that the auxiliary member 46 is engaged with the first member 22.
Once the frame-like engagement portion 201 is engaged with the slit 141 and its neighboring members, a high engagement strength can be obtained. Therefore, when the first member 22 and the auxiliary member 46 are subjected to the welding process, large vibration and impact are caused. Alternatively, the position of the auxiliary member 46 does not shift or is difficult to shift even when an inclination or the like acts. Therefore, the welding location once positioned does not shift or is difficult to shift, so that the working efficiency of the welding process is improved.

図10(C)及び図10(D)に示す補助部材47及び48は、差込規制部182と挿通部19と爪状係合部202又は203とを有する。なお、差込規制部182及び挿通部19は、補助部材45の差込規制部182及び挿通部19と同様の部材である。
爪状係合部202は、挿通部19の挿通方向に対して直交する方向の内側に向かって突出する爪状部材である。
挿通部19を2つのスリット141及び141を挿通する際には、爪状係合部202をその突出方向とは逆の外側方向に変位させて***部16の外側面に摺接させ、挿通部19の先端が2つのスリット141及び141を挿通した時に、爪状係合部202が内側方向に変位して初期位置に戻る。これにより、爪状係合部202が、***部16の端部に引っ掛かった状態になるので、第1部材22に対する補助部材47の係合状態が実現する。
爪状係合部203は、挿通部19の挿通方向に対して直交する方向の外側に向かって突出する爪状部材である。
挿通部19を2つのスリット141及び141を挿通する際には、爪状係合部203をその突出方向とは逆の内側方向に変位させて、挿通部19と共にスリット141を挿通し、爪状係合部203を***部16の内側面に摺接させ、挿通部19の先端が2つのスリット141及び141を挿通した時に、爪状係合部203が外側方向に変位して初期位置に戻る。これにより、爪状係合部203が、***部16の端部に引っ掛かった状態になるので、第1部材22に対する補助部材48の係合状態が実現する。
爪状係合部202及び203がスリット141及びその近傍の部材に一旦係合すると、高い係合強度を得られるので、第1部材22及び補助部材47及び48が溶接工程に供される際に大きな振動、衝撃又は傾斜等が作用しても補助部材47及び48の位置がずれない又はずれ難い。したがって、一旦位置決めした溶接箇所がずれない又はずれ難いこととなるので、溶接工程の作業効率が向上する。
The auxiliary members 47 and 48 shown in FIGS. 10C and 10D have an insertion restricting portion 182, an insertion portion 19, and a claw-like engaging portion 202 or 203. The insertion restriction part 182 and the insertion part 19 are the same members as the insertion restriction part 182 and the insertion part 19 of the auxiliary member 45.
The claw-like engaging portion 202 is a claw-like member that protrudes inward in a direction orthogonal to the insertion direction of the insertion portion 19.
When the insertion part 19 is inserted through the two slits 141 and 141, the claw-like engagement part 202 is displaced in the outer direction opposite to the protruding direction so as to be slidably contacted with the outer surface of the raised part 16, and the insertion part When the tip of 19 is inserted through the two slits 141 and 141, the claw-like engaging portion 202 is displaced inward and returns to the initial position. As a result, the claw-like engaging portion 202 is hooked on the end portion of the raised portion 16, so that the auxiliary member 47 is engaged with the first member 22.
The claw-like engaging portion 203 is a claw-like member that protrudes outward in a direction orthogonal to the insertion direction of the insertion portion 19.
When inserting the two slits 141 and 141 through the insertion part 19, the claw-like engagement part 203 is displaced in the inner direction opposite to the protruding direction, and the slit 141 is inserted together with the insertion part 19 to form a claw-like shape. When the engaging portion 203 is brought into sliding contact with the inner surface of the raised portion 16 and the tip of the insertion portion 19 is inserted through the two slits 141 and 141, the claw-like engaging portion 203 is displaced outward and returns to the initial position. . As a result, the claw-like engaging portion 203 is hooked on the end portion of the raised portion 16, so that the auxiliary member 48 is engaged with the first member 22.
When the claw-like engaging portions 202 and 203 are once engaged with the slit 141 and the members in the vicinity thereof, high engagement strength can be obtained. Therefore, when the first member 22 and the auxiliary members 47 and 48 are subjected to the welding process. The positions of the auxiliary members 47 and 48 do not shift or are difficult to shift even when large vibrations, impacts, or inclinations are applied. Therefore, the welding location once positioned does not shift or is difficult to shift, so that the working efficiency of the welding process is improved.

図10(E)に示す補助部材49は、差込規制部182と挿通部19と凸状係合部204とを有する。なお、差込規制部182及び挿通部19は、補助部材45の差込規制部182及び挿通部19と同様の部材である。
凸状係合部204は、挿通部19の表面でかつ差込規制部182の延在方向と同一方向に形成される突起状部材である。
挿通部19を2つのスリット141及び141を挿通すれば、凸状係合部204もスリットを挿通し、天板部17の端部に凸状係合部204が引っ掛かった状態になる。よって、第1部材22に対する補助部材49の係合は、挿通部19を2つのスリット141及び141に挿通するだけで実現する。
補助部材49は、凸状係合部204を意図的に変位させなくとも、挿通部19をスリット141に挿通させるだけで係合状態が実現するので、本発明に係る異材接合方法の係合工程を容易に実行可能である。これにより、本発明に係る異材接合方法の全体的な作業効率も向上する。
The auxiliary member 49 shown in FIG. 10 (E) has an insertion restricting portion 182, an insertion portion 19, and a convex engagement portion 204. The insertion restriction part 182 and the insertion part 19 are the same members as the insertion restriction part 182 and the insertion part 19 of the auxiliary member 45.
The convex engaging portion 204 is a protruding member formed on the surface of the insertion portion 19 and in the same direction as the extending direction of the insertion restricting portion 182.
If the two slits 141 and 141 are inserted through the insertion portion 19, the convex engagement portion 204 is also inserted through the slit, and the convex engagement portion 204 is hooked on the end of the top plate portion 17. Therefore, the engagement of the auxiliary member 49 with the first member 22 is realized only by inserting the insertion part 19 into the two slits 141 and 141.
Even if the auxiliary member 49 does not intentionally displace the convex engaging portion 204, the engaging state is realized only by inserting the insertion portion 19 into the slit 141. Therefore, the engaging step of the dissimilar material joining method according to the present invention is realized. Is easily feasible. This also improves the overall work efficiency of the dissimilar material joining method according to the present invention.

図11には、図7(D)に示した第1部材23に対して係合可能な補助部材410、及び411を示している。なお、図11(A)及び図11(B)に示す白抜き矢印は、挿入部191を、第1部材23のスリット142に挿入する方向である。   FIG. 11 shows auxiliary members 410 and 411 that can be engaged with the first member 23 shown in FIG. Note that white arrows shown in FIGS. 11A and 11B are directions in which the insertion portion 191 is inserted into the slit 142 of the first member 23.

図11(A)に示す補助部材410は、挿入部191と懸架型係合部205とを有する。挿入部191は、図10に示した挿通部19と同様の機能を有する部材であり、第1部材23のスリット142を挿通する板状部材である。また、挿入部191は、挿通部19と同様に、溶接工程に供された時に溶着部と成る部位である。
懸架型係合部205は、挿入部191の端部が、係合工程を実行するときの補助部材45の差込み方向に直交又は略直交して折曲され、更に該直交又は直交する方向に突出する部材である。懸架型係合部205は、スリット142の長手方向に沿った大きさがスリット142よりも大きく形成されて成る部材である。
挿入部191は、第1部材23のスリット142に挿入される。スリット142に挿入部191全体が挿入された後に、スリット142の長手方向よりも大きく形成されて成る懸架型係合部205がスリット142に挿入されずに当接することによって、挿入部191のスリット142への挿入動作、つまり補助部材410の差し込み動作が規制される。補助部材410の差込み動作の規制された状態が、第1部材23と補助部材410とが係合している状態である。
懸架型係合部205がスリット142に挿入されずに当接すると、補助部材410全体が懸架型係合部205によりスリット142に懸架された状態と成る。
挿入部191をスリット142に挿入するだけで係合工程が完了するので、本発明に係る異材接合方法の係合工程を容易に実行可能である。これにより、本発明に係る異材接合方法の全体的な作業効率も向上する。
An auxiliary member 410 illustrated in FIG. 11A includes an insertion portion 191 and a suspension type engagement portion 205. The insertion portion 191 is a member having the same function as the insertion portion 19 shown in FIG. 10 and is a plate-like member that passes through the slit 142 of the first member 23. Moreover, the insertion part 191 is a site | part used as a welding part when it uses for a welding process similarly to the insertion part 19. FIG.
The suspension type engaging portion 205 is bent at the end of the insertion portion 191 perpendicular or substantially perpendicular to the insertion direction of the auxiliary member 45 when the engaging step is executed, and further protrudes in the perpendicular or perpendicular direction. It is a member to do. The suspension type engaging portion 205 is a member formed such that the size along the longitudinal direction of the slit 142 is larger than that of the slit 142.
The insertion part 191 is inserted into the slit 142 of the first member 23. After the entire insertion portion 191 is inserted into the slit 142, the suspension type engagement portion 205 formed larger than the longitudinal direction of the slit 142 abuts without being inserted into the slit 142, whereby the slit 142 of the insertion portion 191 is contacted. Insertion operation, that is, the insertion operation of the auxiliary member 410 is restricted. The state where the insertion operation of the auxiliary member 410 is restricted is a state where the first member 23 and the auxiliary member 410 are engaged.
When the suspension type engaging part 205 comes into contact with the slit 142 without being inserted, the entire auxiliary member 410 is suspended by the suspension type engaging part 205 on the slit 142.
Since the engagement step is completed simply by inserting the insertion portion 191 into the slit 142, the engagement step of the dissimilar material joining method according to the present invention can be easily performed. This also improves the overall work efficiency of the dissimilar material joining method according to the present invention.

図11(B)に示す補助部材411において、上記補助部材410との相違点は、懸架型係合部の形状である。該相違点以外は、挿入部191の形状、大きさ、機能及びスリット142への挿入態様等は共通している。
補助部材411は挿入部191と懸架型係合部206とを有する。懸架型係合部206は、挿入部191の端部が、係合工程を実行するときの補助部材45の差込み方向(白抜き矢印の方向)に直交又は略直交して折曲され、更に再度折曲される板状部材である。挿入部191の端部が一度目の折曲部位に2本の切り込みが形成されて3つの部位に分割されており、該分割部位を互い違いの方向に折曲されている。補助部材410の懸架型係合部205は、スリット142の長手方向に沿った大きさが、スリット142よりも大きく形成されていたのに対し、補助部材411の懸架型係合部206は、懸架型係合部206がスリット142を通過しないように、スリット142の短手方向に折曲されている。
補助部材411の挿入部191は、第1部材23のスリット142に挿入される。スリット142に挿入部191全体が挿入された後に、スリット142の短手方向に折曲されて成る懸架型係合部206がスリット142に挿入されずに当接することによって、挿入部191のスリット142への挿入動作、つまり補助部材411の差し込み動作が規制される。補助部材411の差込み動作の規制された状態が、第1部材23と補助部材411とが係合している状態である。
懸架型係合部206がスリット142に挿入されずに当接すると、補助部材411全体が懸架型係合部206によりスリット142に懸架された状態と成る。
補助部材411は挿入部191をスリット142に挿入するだけで係合工程が完了するので、本発明に係る異材接合方法の係合工程を容易に実行可能である。これにより、本発明に係る異材接合方法の全体的な作業効率も向上する。
In the auxiliary member 411 shown in FIG. 11B, the difference from the auxiliary member 410 is the shape of the suspension type engaging portion. Except for this difference, the shape, size, function, and manner of insertion into the slit 142 are the same.
The auxiliary member 411 has an insertion portion 191 and a suspension type engagement portion 206. The suspension type engaging portion 206 is bent so that the end portion of the insertion portion 191 is orthogonal or substantially orthogonal to the insertion direction of the auxiliary member 45 (the direction of the white arrow) when the engaging step is executed, and again. A plate-like member to be bent. The end of the insertion portion 191 is divided into three parts by forming two cuts in the first bent part, and the divided parts are bent in alternate directions. The suspension type engaging portion 205 of the auxiliary member 410 has a size along the longitudinal direction of the slit 142 larger than that of the slit 142, whereas the suspension type engaging portion 206 of the auxiliary member 411 is suspended. The mold engaging portion 206 is bent in the short direction of the slit 142 so as not to pass through the slit 142.
The insertion portion 191 of the auxiliary member 411 is inserted into the slit 142 of the first member 23. After the entire insertion portion 191 is inserted into the slit 142, the suspension-type engaging portion 206 bent in the short direction of the slit 142 abuts without being inserted into the slit 142, whereby the slit 142 of the insertion portion 191 is contacted. Insertion operation, that is, the insertion operation of the auxiliary member 411 is restricted. The state where the insertion operation of the auxiliary member 411 is restricted is a state where the first member 23 and the auxiliary member 411 are engaged.
When the suspension type engaging portion 206 is brought into contact with the slit 142 without being inserted, the entire auxiliary member 411 is suspended from the slit 142 by the suspension type engaging portion 206.
Since the auxiliary member 411 completes the engaging step only by inserting the insertion portion 191 into the slit 142, the engaging step of the dissimilar material joining method according to the present invention can be easily performed. This also improves the overall work efficiency of the dissimilar material joining method according to the present invention.

本発明に係る異材接合体において第1部材がスリットを有する実施形態として、図12に示す実施形態を挙げることができる。図7(C)及び図7(D)に示したスリット141及び142は縁部52及び53に平行又は略平行に形成されていたのに対して、図12に示す第1部材24は、縁部54に対して直交又は略直交するスリット143が複数形成されている。図12(A)は係合前の第1部材24と補助部材412とを示し、図12(B)は係合後の第1部材24と補助部材412とを示している。
第1部材24は、縁部54近傍に沿って開口部29が複数形成されている。縁部54に対して直交又は略直交するスリット143が縁部54から補助部材412の差し込み方向に沿って形成されている。一つの開口部29と隣接する別の開口部29との間であって、一つのスリット143と隣接する別のスリット143との間には、スリット143の方向に沿って長手方向を有する平面視矩形状の陥没部位が凹部27として形成されている。すなわち、図12(A)に示されるように、第1部材24は、開口部29が設けられる部位と凹部27とは交互に形成されている。
補助部材412は、凹部27に挿入される凹部挿入部28と、溶着部74とが交互に形成されている。凹部挿入部28及び溶着部74は、それぞれが平面視矩形状を成し、交互に高低差を以って配設される。第1部材24の開口部29が形成される部位と凹部27が形成される部位との高低差に合わせて、凹部挿入部28及び溶着部74の高低差を設定することができる。該高低差が大き過ぎると、第1部材24と補助部材412とが係合し難くなることがあるので、第1部材24及び補助部材412が係合した時にガタつきが無い又は少ない程度の高低差に調整するのが良い。
図12(B)に示すように、第1部材24と補助部材412とが係合すると、凹部27に凹部挿入部28が挿入され、開口部29から溶接用電極を挿入して溶着部74を溶接可能となる。第1部材24及び補助部材412がそれぞれ逆の高低差を以って形成されていることにより、係合させると該高低差を埋めるようにして互い違いに噛み合うので、高い係合強度を得ることができる。
更に、図12に示す第1部材24及び補助部材412は、隣接する溶接箇所が連結されて成る形状を有するので、係合工程を実行することによって、溶接箇所が一つ決定すれば、全ての溶接箇所も決定される。すなわち、本発明に係る異材接合方法の全体的な作業効率が向上する。
The embodiment shown in FIG. 12 can be cited as an embodiment in which the first member has a slit in the dissimilar material joined body according to the present invention. The slits 141 and 142 shown in FIGS. 7C and 7D are formed in parallel or substantially parallel to the edges 52 and 53, whereas the first member 24 shown in FIG. A plurality of slits 143 that are orthogonal or substantially orthogonal to the portion 54 are formed. FIG. 12A shows the first member 24 and the auxiliary member 412 before engagement, and FIG. 12B shows the first member 24 and the auxiliary member 412 after engagement.
The first member 24 has a plurality of openings 29 along the vicinity of the edge 54. A slit 143 that is orthogonal or substantially orthogonal to the edge portion 54 is formed along the insertion direction of the auxiliary member 412 from the edge portion 54. A plan view having a longitudinal direction along the direction of the slit 143 between one opening 29 and another adjacent opening 29, and between one slit 143 and another adjacent slit 143. A rectangular depression is formed as the recess 27. That is, as shown in FIG. 12A, in the first member 24, the portions where the openings 29 are provided and the recesses 27 are alternately formed.
In the auxiliary member 412, recessed portion insertion portions 28 inserted into the recessed portions 27 and welded portions 74 are alternately formed. The recessed portion insertion portion 28 and the welded portion 74 each have a rectangular shape in plan view, and are alternately arranged with a height difference. The height difference between the recessed portion insertion portion 28 and the welded portion 74 can be set according to the height difference between the portion where the opening 29 of the first member 24 is formed and the portion where the recessed portion 27 is formed. If the height difference is too large, the first member 24 and the auxiliary member 412 may not be easily engaged. Therefore, there is no backlash when the first member 24 and the auxiliary member 412 are engaged. It is good to adjust to the difference.
As shown in FIG. 12B, when the first member 24 and the auxiliary member 412 are engaged with each other, the recessed portion insertion portion 28 is inserted into the recessed portion 27, and the welding electrode is inserted from the opening portion 29. It becomes possible to weld. Since the first member 24 and the auxiliary member 412 are formed with opposite height differences, when engaged, the first member 24 and the auxiliary member 412 are engaged with each other so as to fill the height difference, so that high engagement strength can be obtained. it can.
Furthermore, since the first member 24 and the auxiliary member 412 shown in FIG. 12 have a shape formed by connecting adjacent welding locations, if one welding location is determined by executing the engaging step, all the welding locations are determined. The weld location is also determined. That is, the overall work efficiency of the dissimilar material joining method according to the present invention is improved.

本発明に係る異材接合方法において、補助部材を第1部材の縁部から差し込むことにより係合工程を実行する複数の実施形態を説明した。ここで、差し込み動作に拠らずに係合工程を実行可能な実施形態について、図13〜図15を参照しつつ以下に説明する。
図13〜図15には、補助部材とその補助部材に係合する貫通孔を有する第1部材とを示す。
In the dissimilar material joining method according to the present invention, a plurality of embodiments have been described in which the engaging step is performed by inserting the auxiliary member from the edge of the first member. Here, an embodiment capable of performing the engaging step without relying on the insertion operation will be described below with reference to FIGS.
13 to 15 show an auxiliary member and a first member having a through hole that engages with the auxiliary member.

図13(A)には、補助部材413を示した。補助部材413は、円筒部31と鍔部321とフランジ331とを有する。円筒部31は有底円筒体であり、その底面が溶着部75である。鍔部321は、円筒部31の開口部分から外側に張り出して形成されている。フランジ331は、円筒部31の周側面において円周方向に沿って形成される突出部である。フランジ331は、図13(A)には図示していないが、円筒部31の周側面における約180°反対側にも設けられている。
図13(B)に平面図を示す第1部材2は、図4に示した第1部材2と同様の部材である。第1部材2と補助部材413とは係合可能である。第1部材2と補助部材413との係合は、補助部材413の溶着部75側から貫通孔6に挿入し、フランジ331が溶着部75側に抜けたところで達成される。補助部材413の挿入方向には鍔部321によって抜けないようになっており、挿入方向とは逆方向にはフランジ331によって容易には抜けないようになっている。
FIG. 13A shows the auxiliary member 413. The auxiliary member 413 includes a cylindrical portion 31, a flange portion 321, and a flange 331. The cylindrical portion 31 is a bottomed cylindrical body, and the bottom surface thereof is a welded portion 75. The flange portion 321 is formed to project outward from the opening portion of the cylindrical portion 31. The flange 331 is a protruding portion formed along the circumferential direction on the peripheral side surface of the cylindrical portion 31. Although not shown in FIG. 13A, the flange 331 is also provided on the opposite side of the circumferential side surface of the cylindrical portion 31 by about 180 °.
The first member 2 whose plan view is shown in FIG. 13B is the same member as the first member 2 shown in FIG. The first member 2 and the auxiliary member 413 can be engaged. The engagement between the first member 2 and the auxiliary member 413 is achieved when the auxiliary member 413 is inserted into the through hole 6 from the welding portion 75 side of the auxiliary member 413 and the flange 331 is pulled out to the welding portion 75 side. The auxiliary member 413 is prevented from being pulled out by the flange portion 321 in the insertion direction, and is not easily pulled out by the flange 331 in the direction opposite to the insertion direction.

図14(A)には、補助部材414を示した。補助部材414は、鍔部322とフランジ332とを有する。鍔部322は、端縁部が外側に張り出し、略円錐台形状を成す部位である。フランジ332は、平面視矩形状を成す板体であり、鍔部322における円錐台の中央部に連結されている。鍔部322とフランジ332とは、補助部材414の貫通孔62への挿入方向に沿って離れた位置に設けられている。なお、フランジ332は、溶着部となる部位である。
図14(B)に平面図を示す第1部材25は、縁部55近傍に円と該円の円周から矩形が延在する形状の貫通孔62を有する。第1部材25と補助部材414とは係合可能である。第1部材25と補助部材414との係合は、補助部材414のフランジ332側から貫通孔62に挿入し、フランジ332を貫通孔62の矩形を成す部位を通過させ、更にフランジ332が貫通孔62から抜けないように、補助部材414を例えば90°回動させたところで達成される。補助部材414はフランジ332が貫通孔62の矩形を成す部位のみを通過するようになっているので、補助部材414を貫通孔62に挿入して回動させれば容易には抜けないようになっている。
FIG. 14A shows the auxiliary member 414. The auxiliary member 414 has a flange 322 and a flange 332. The collar portion 322 is a portion having an end portion protruding outward and having a substantially truncated cone shape. The flange 332 is a plate body having a rectangular shape in plan view, and is connected to the central portion of the truncated cone in the flange portion 322. The flange portion 322 and the flange 332 are provided at positions separated along the insertion direction of the auxiliary member 414 into the through hole 62. In addition, the flange 332 is a site | part used as a welding part.
The first member 25, whose plan view is shown in FIG. 14B, has a circle and a through hole 62 in the shape of a rectangle extending from the circumference of the circle near the edge 55. The first member 25 and the auxiliary member 414 can be engaged. The first member 25 and the auxiliary member 414 are engaged with each other by inserting the auxiliary member 414 into the through hole 62 from the flange 332 side, allowing the flange 332 to pass through the portion of the through hole 62 that is rectangular, and the flange 332 is the through hole. This is achieved when the auxiliary member 414 is rotated by, for example, 90 ° so that it does not come off from 62. Since the auxiliary member 414 passes only through the part where the flange 332 forms the rectangular shape of the through hole 62, the auxiliary member 414 cannot be easily removed if the auxiliary member 414 is inserted into the through hole 62 and rotated. ing.

図15(A)には、補助部材415を示した。補助部材415は、鍔部323とフランジ333とを有する。鍔部323は、外側に張り出す部位である。フランジ333は、平面視略六角形を成す板体であり、鍔部323に連結されている。鍔部323とフランジ333とは、補助部材415の貫通孔63への挿入方向に沿って離れた位置に設けられている。なお、フランジ333は、溶着部となる部位である。
図15(B)に平面図を示す第1部材26は、縁部56近傍に矩形状の貫通孔63を有する。第1部材26と補助部材415とは係合可能である。第1部材26と補助部材415との係合は、補助部材415のフランジ333側から貫通孔64に挿入し、フランジ333を貫通孔63に通過させ、更にフランジ333が貫通孔63から抜けないように、補助部材415を例えば90°回動させたところで達成される。補助部材415はフランジ333が貫通孔63の矩形を成す部位のみを通過するようになっているので、補助部材415を貫通孔63に挿入して回動させれば容易には抜けないようになっている。
FIG. 15A shows the auxiliary member 415. The auxiliary member 415 has a flange 323 and a flange 333. The collar part 323 is a part projecting outward. The flange 333 is a plate body having a substantially hexagonal shape in plan view, and is connected to the flange portion 323. The flange 323 and the flange 333 are provided at positions separated along the insertion direction of the auxiliary member 415 into the through hole 63. In addition, the flange 333 is a site | part used as a welding part.
The first member 26 shown in a plan view in FIG. 15B has a rectangular through hole 63 in the vicinity of the edge portion 56. The first member 26 and the auxiliary member 415 can be engaged. The first member 26 and the auxiliary member 415 are engaged with each other by inserting the auxiliary member 415 into the through hole 64 from the flange 333 side, passing the flange 333 through the through hole 63, and preventing the flange 333 from coming out of the through hole 63. Further, this is achieved when the auxiliary member 415 is rotated by 90 °, for example. Since the auxiliary member 415 passes only through the part where the flange 333 forms the rectangular shape of the through hole 63, the auxiliary member 415 cannot be easily removed if the auxiliary member 415 is inserted into the through hole 63 and rotated. ing.

図8〜図15に示した様々な補助部材は、第1部材に係合され、各補助部材の溶着部において第2部材に直接溶接されることにより、溶接強度の低下を生じ得る金属間化合物が形成しない。つまり、各実施形態に係る補助部材を用いることによって、金属間化合物が形成してしまう材料同士の溶接は行わないので、異種の材料を含む第1部材と第2部材とを容易に接合可能である。
また、溶接工程の前に実行される係合工程では、各補助部材を第1部材の縁部から差し込んで係合させるだけであるので、容易に実行可能であり、車両用部品の製造工程を大幅に変更する必要が無い。例えば、図8〜図12に示した実施形態に係る各補助部材は、図3に示した部品プレス成形工程S1と車体溶接工程S2との間に、作業者が特別な機器を用いることなく、手で補助部材を把持して第1部材に差し込むだけで、係合工程を実行することができる。
図8に示す補助部材41〜43は、貫通孔6内への凸部71〜73の挿入と、挟持すること又は引っ掛けることによって第1部材2に対して係合している。したがって、係合工程後で溶接工程までに衝撃、振動、傾斜等が第1部材2に作用したとしても、補助部材41〜43が第1部材2から脱離することは無い又は脱離し難い。よって、溶接工程において溶接箇所と成る補助部材41〜43の取付位置がずれないので、溶接箇所がずれてしまうことも無い又は起き難い。
また、図9〜図15に示す各補助部材は、各補助部材の形状に応じた第1部材21〜23を用いることによって係合状態を実現可能であり、一旦係合すれば容易に脱離することは無い又は脱離し難い。よって、溶接工程において溶接箇所と成る補助部材の取付位置がずれないので、溶接箇所がずれてしまうことも無い又は起き難い。
各補助部材の大きさは、第1部材に係合させても第1部材全体を被覆せず、第1部材の縁部近傍の領域に取付けられる程度であるので、例えば車両用部品の製造工程において他の作業及び他の部品の取付け等を妨げることはない。
図8及び図10〜図15に示した補助部材は、第1部材に対して係合状態と成り、溶接時においてその一部が露出しているので、作業者が溶接箇所を視認により判別し易い。
以上により、異種の材料を含む部材を接合することのできる異材接合方法は、例えば従来の車両用部品の製造工程に対して煩雑な別工程を付加する必要が無く、係合工程も容易に実行可能であり、溶接箇所がずれない又はずれ難く、他の作業及び他の部品の取付け等を妨げず、溶接箇所が判別し易いので、作業効率が高い。
The various auxiliary members shown in FIG. 8 to FIG. 15 are engaged with the first member, and are welded directly to the second member at the welded portion of each auxiliary member, so that the intermetallic compound can cause a decrease in welding strength. Does not form. That is, by using the auxiliary member according to each embodiment, welding of materials that form an intermetallic compound is not performed, so that the first member and the second member containing different materials can be easily joined. is there.
Moreover, in the engagement process performed before a welding process, since each auxiliary member is only inserted and engaged from the edge part of a 1st member, it can be performed easily and the manufacturing process of the components for vehicles is carried out. There is no need to make significant changes. For example, each auxiliary member according to the embodiment shown in FIGS. 8 to 12 can be used without any special equipment by the operator between the component press molding step S1 and the vehicle body welding step S2 shown in FIG. The engagement step can be performed simply by gripping the auxiliary member by hand and inserting it into the first member.
The auxiliary members 41 to 43 shown in FIG. 8 are engaged with the first member 2 by inserting the convex portions 71 to 73 into the through holes 6 and pinching or hooking them. Therefore, even if an impact, vibration, inclination, or the like acts on the first member 2 after the engagement step and before the welding step, the auxiliary members 41 to 43 are not detached from the first member 2 or are not easily detached. Therefore, since the attachment positions of the auxiliary members 41 to 43 serving as welding locations are not shifted in the welding process, the welding locations are not shifted or hardly occur.
Moreover, each auxiliary member shown in FIGS. 9 to 15 can be engaged by using the first members 21 to 23 corresponding to the shape of each auxiliary member, and is easily detached once engaged. There is nothing to do or it is difficult to detach. Therefore, since the attachment position of the auxiliary member which becomes a welding location does not shift in the welding process, the welding location does not shift or hardly occurs.
The size of each auxiliary member does not cover the entire first member even when engaged with the first member, and can be attached to a region near the edge of the first member. It does not interfere with other work and installation of other parts.
The auxiliary members shown in FIGS. 8 and 10 to 15 are engaged with the first member, and a part of the auxiliary member is exposed at the time of welding. easy.
As described above, the dissimilar material joining method capable of joining members containing different kinds of materials does not require a complicated separate process, for example, with respect to the conventional manufacturing process for vehicle parts, and the engagement process is also easily performed. It is possible, the welding location does not shift or is difficult to shift, and does not interfere with other work and the mounting of other parts, and the welding location is easy to distinguish, so the work efficiency is high.
