以下にこの発明の実施例を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

まず、この実施例の他部材への溶接による二重管管端接続部位置決め構造を図面に基づいて説明する。

 Also not a will be described with reference to the double tube pipe end connecting portions positioning structure by welding to the other members of this embodiment in the drawings.

図１はこの実施例の他部材への溶接による二重管管端接続部位置決め構造を示す図、図２は内管のプレス成形時の状態を示す斜視図、図３はプレス成形時に内管の管端に残る母材の一部を外向き係止フランジとして切り残す状態を示す断面図である。
この実施例の他部材への溶接による二重管管端接続部位置決め構造は、ディフューザ（内管）１と、遮熱パイプ（外管）２と、触媒コンバータ（他部材）３と、を備えている。 FIG. 1 is a diagram showing a structure for positioning a double pipe pipe end connecting portion by welding to another member of this embodiment, FIG. 2 is a perspective view showing a state during press molding of the inner pipe, and FIG. 3 is an inner pipe during press molding. It is sectional drawing which shows the state which leaves a part of base material which remains in the pipe end of this as an outward locking flange.
The double pipe end connection positioning structure by welding to another member of this embodiment includes a diffuser (inner tube) 1, a heat shield pipe (outer tube) 2, and a catalytic converter (other member) 3. ing.

さらに詳述すると、前記ディフューザ１は、異径管１１と小径曲管１２とで構成されている。
前記異径管１１は、図２に示すように、板状の母材から深絞りプレス成形によって形成されるもので、小径側に形成される底部分をカットすると共に、図３に示すように、大径側管端に残る母材部１１ａの一部を大径側管端に形成される外向き係止フランジ（凸部）１１ｂとして残した状態でカットすることにより形成される。 More specifically, the diffuser 1 includes a different diameter pipe 11 and a small diameter bent pipe 12.
As shown in FIG. 2, the different diameter pipe 11 is formed by deep drawing press molding from a plate-shaped base material, and cuts the bottom portion formed on the small diameter side, as shown in FIG. It is formed by cutting while leaving a part of the base material portion 11a remaining at the large diameter side pipe end as an outward locking flange (convex portion) 11b formed at the large diameter side tube end.

前記小径曲管１２は、一方の管端が異径管１１の小径側管端の内側に差し込まれた状態で接続されると共に、もう一方の管端側は図示を省略したエキゾーストマニホールドにおける集合パイプの下流側管端に対し遮熱パイプ２と共にフランジ接続されるようになっている。   The small-diameter curved pipe 12 is connected in a state in which one pipe end is inserted inside the small-diameter side pipe end of the different-diameter pipe 11, and the other pipe end side is a collective pipe in an exhaust manifold (not shown). A flange connection is made with the heat shield pipe 2 to the downstream pipe end.

前記遮熱パイプ２は、エンジンから排気された排気ガスの温度が触媒コンバータ３より上流側のディフューザ１内を流れる際に外気温によって低下しないようにその外側を覆って保温する役目をなすもので、前記ディフューザ１における異径管１１の大径管端と小径曲管１２の上流側管端外周面に両管端をそれぞれ当接させた状態で中間部分に断熱空気層ａが形成されるようになっている。   The heat shield pipe 2 serves to cover the outside and keep the temperature so that the temperature of the exhaust gas exhausted from the engine does not decrease due to the outside air temperature when flowing in the diffuser 1 upstream of the catalytic converter 3. In the diffuser 1, the heat insulating air layer a is formed in the intermediate portion in a state where the pipe ends are in contact with the outer peripheral surface of the large diameter pipe end of the different diameter pipe 11 and the upstream side pipe end of the small diameter curved pipe 12, respectively. It has become.

そして、遮熱パイプ２の大径側管端をディフューザ１における異径管１１の大径管端に形成された外向き係止フランジ１１ｂに係止させることにより、ディフューザ１と遮熱パイプ２による二重管の下流側管端（二重管管端）の位置決めが行なわれるもので、この位置決めされた状態で触媒コンバータ３の外筒３１に接続するための溶接が行なわれるようになっている。   Then, the large-diameter side pipe end of the heat shield pipe 2 is locked to the outward locking flange 11b formed at the large-diameter pipe end of the different diameter pipe 11 in the diffuser 1, whereby the diffuser 1 and the heat shield pipe 2 are used. Positioning of the downstream pipe end (double pipe pipe end) of the double pipe is performed, and welding for connecting to the outer cylinder 31 of the catalytic converter 3 is performed in this positioned state. .

即ち、前記異径管１１の大径側管端は、前記遮熱パイプ２の大径側管端と共に触媒コンバータ３の外筒３１に対し溶接により接続される。
なお、前記外向き係止フランジ１１の外向き突出長さとしては、溶接ビードｂ内で溶け込む大きさに設定することが望ましく、このため、この実施例では、遮熱パイプ２の大径側管端部分の板厚以下の長さに設定されている。 That is, the large-diameter side pipe end of the different diameter pipe 11 is connected to the outer cylinder 31 of the catalytic converter 3 by welding together with the large-diameter side pipe end of the heat shield pipe 2.
The outward protruding length of the outward locking flange 11 is preferably set to a size that melts in the weld bead b. Therefore, in this embodiment, the large-diameter side tube of the heat shield pipe 2 is used. The length is set to be equal to or less than the thickness of the end portion.

次に、この実施例の作用・効果を説明する。
この実施例では上述のように、深絞りプレス成形時にディフューザ１を構成する異径管１１の大径側管端に残る母材部１１ａの一部を外向き係止フランジ１１ｂとして残し、この外向き係止フランジ部１１ｂに遮熱パイプ２の大径側管端を係止させた状態で触媒コンバータ３の外筒３１への溶接を行なうように構成するようにしたことで、両管端の位置ずれ、特に遮熱パイプ２に対し異径管１１が内側にずれることによって生じる溶接不良の発生を防止することができると共に、遮熱パイプ２に対する異径管１１の位置決めが簡単に行なわれるため、触媒コンバータ３に対する溶接作業を迅速かつ効率的に行なうことができるようになるという効果が得られる。 Next, the operation and effect of this embodiment will be described.
In this embodiment, as described above, a part of the base material portion 11a remaining at the large diameter side pipe end of the different diameter tube 11 constituting the diffuser 1 at the time of deep drawing press forming is left as the outward locking flange 11b. Since welding to the outer cylinder 31 of the catalytic converter 3 is performed in a state where the large-diameter side pipe end of the heat shield pipe 2 is locked to the direction locking flange portion 11b, both pipe ends are It is possible to prevent the occurrence of welding failure caused by positional displacement, in particular, displacement of the different diameter pipe 11 inward with respect to the heat shield pipe 2, and the positioning of the different diameter pipe 11 with respect to the heat shield pipe 2 is easily performed. The effect that the welding operation for the catalytic converter 3 can be performed quickly and efficiently is obtained.

また、深絞りプレス成形時にディフューザ１の管端に残る母材の一部を係止フランジ１１ｂとして有効利用することができると共に、該係止フランジ１１ｂが全周に亘る環状に形成されることで、溶接を周方向均一に行なうことができるようになる。   Further, a part of the base material remaining at the pipe end of the diffuser 1 at the time of deep drawing press can be effectively used as the locking flange 11b, and the locking flange 11b is formed in an annular shape over the entire circumference. The welding can be performed uniformly in the circumferential direction.

また、上述のように、前記外向き係止フランジ１１ｂの突出長さが遮熱パイプ２の板厚以下に設定されることにより、異径管１１と遮熱パイプ２の大径側両管端にほぼ均一に溶接ビードｂをのせることができ、これにより、接続強度を高めることができるようになる。   Further, as described above, when the protruding length of the outward locking flange 11b is set to be equal to or less than the plate thickness of the heat shield pipe 2, both the large diameter side pipe ends of the different diameter pipe 11 and the heat shield pipe 2 are arranged. The weld bead b can be placed almost uniformly on the surface, thereby increasing the connection strength.

以上本実施例を説明してきたが、本発明は上述の実施例に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等があっても、本発明に含まれる。
例えば、実施例では、ディフューザ１と遮熱パイプ２による二重管を例にとって説明したが、全ての二重管の管端を他部材の外周に対し溶接固定する場合に適用することができる。 Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.
For example, in the embodiment, the description has been given by taking the double pipes including the diffuser 1 and the heat shield pipe 2 as an example, but the present invention can be applied to the case where the pipe ends of all the double pipes are welded to the outer periphery of the other member.

また、実施例では、異径管（内管）１１における外向き係止フランジ１１ｂの突出長さを遮熱パイプ（外管）２の大径側管端部分の板厚以下の長さに設定する場合を例にとったが、溶接ビードｂ内で溶け込む程度の長さであれば遮熱パイプ（外管）２の大径側管端部分の板厚より長くすることができる。   In the embodiment, the protruding length of the outward locking flange 11 b in the different diameter pipe (inner pipe) 11 is set to a length equal to or less than the plate thickness of the large diameter side pipe end portion of the heat shield pipe (outer pipe) 2. However, if the length is such that it melts in the weld bead b, it can be made longer than the plate thickness of the large-diameter side tube end portion of the heat shield pipe (outer tube) 2.

また、実施例では、係止フランジ１１ｂとして環状に形成したが、内管を構成するディフューザ１のプレス成形時に、該ディフューザ１の管端に凸部を複数個形成するようにしてもよい。   Further, in the embodiment, the locking flange 11b is formed in an annular shape, but a plurality of convex portions may be formed at the pipe end of the diffuser 1 during press molding of the diffuser 1 constituting the inner pipe.
