Description

本発明は、結合構造とその結合方法に関するものである。   The present invention relates to a bonding structure and a bonding method thereof.

通常、ロケットは、機軸方向に分かれた複数の円筒部品を連結することによって組み立てる。複数の円筒部品の繋ぎ目にはフランジが設けられている。従来のロケットの組み立ては、隣り合った円筒部品のフランジを大量のボルトで連結することにより行われていた。ロケットを組み立てるにあたり、１か所のフランジを留めるのに１００本以上のボルトが使用された例もある。このようなロケットは、例えば非特許文献１に開示されている。   Usually, the rocket is assembled by connecting a plurality of cylindrical parts separated in the axial direction. A flange is provided at the joint of the plurality of cylindrical parts. Conventional rocket assembly has been accomplished by connecting the flanges of adjacent cylindrical parts with a large number of bolts. In assembling the rocket, in some cases, more than 100 bolts were used to fasten one flange. Such a rocket is disclosed, for example, in Non-Patent Document 1.

“ＰＲＯＤＵＣＴＩＯＮ ＡＴ ＳＰＡＣＥＸ”、［ｏｎｌｉｎｅ］、２０１３年９月２４日、［平成２９年４月７日検索］、インターネット〈ＵＲＬ：ｈｔｔｐ：／／ｗｗｗ．ｓｐａｃｅｘ．ｃｏｍ／ｎｅｗｓ／２０１３／０９／２４／ｐｒｏｄｕｃｔｉｏｎ−ｓｐａｃｅｘ〉“PRODUCTION AT SPACEX”, [online], September 24, 2013, [search on April 7, 2017], Internet <URL: http: // www. spacex. com / news / 2013/09/24 / production-spacex>

上述したように、従来のロケットの組み立ては大量のボルトでフランジを連結することで行われるため、ロケットを完成させるには、１本１本のボルトをトルク管理しなければならない。ボルトはロケットの全周を取り囲むように多数存在するため、ロケットの組み立て作業には、多大な手間と時間を必要としていた。
そのため、ロケットの組み立て作業をさらに短時間で行いたいという要求があった。 As described above, since the assembly of the conventional rocket is performed by connecting the flanges with a large amount of bolts, in order to complete the rocket, it is necessary to torque manage each bolt. Because a large number of bolts exist around the entire circumference of the rocket, the assembly work of the rocket required a great deal of effort and time.
Therefore, there is a demand to carry out the assembly work of the rocket in a shorter time.

本発明は上述した問題点を解決するために創案されたものである。すなわち本発明の目的は、組み立てにかかる作業時間を短縮できる結合構造とその結合方法を提供することにある。   The present invention has been made to solve the above-mentioned problems. That is, an object of the present invention is to provide a coupling structure and a coupling method that can reduce the working time required for assembly.

本発明によれば、互いの端面を突き合わせて結合する２つの部品の結合部に互いに対向して同軸上に位置する突起部と凹溝とを該結合部に沿って互いに間隔を隔てて複数備え、
各凹溝は、前記結合部から前記軸に沿って窪み、前記結合部に開口する開口部と、前記開口部の奥側に位置し前記結合部が延びる結合方向における幅が前記開口部より大きい拡大溝部と、を有し、
各突起部は、前記結合部から前記軸に沿って突出し、前記結合方向における幅が前記開口部より大きい拡大部と、前記突起部の先端に位置し前記開口部より前記幅が小さい先端部と、前記拡大部と該先端部とを滑らかに繋ぐテーパ面と、前記拡大部を前記結合方向に間隔を隔てて分割するスリットと、を有し、
複数の前記軸は、互いに平行に延び、
前記突起部と前記凹溝は、前記部品が前記軸方向に移動することにより嵌合する、結合構造が提供される。 According to the present invention, the coupling portion of the two parts in which the end faces are butt-joined to each other is provided with a plurality of projections and concave grooves coaxially located opposite to each other and spaced apart from each other along the coupling portion. ,
Each recessed groove is recessed along the axis from the coupling portion, and an opening portion opened to the coupling portion, and a width in a coupling direction which is positioned on the back side of the opening and the coupling portion extends is larger than the opening And an enlarged groove portion,
Each protrusion protrudes along the axis from the connecting portion, and an enlarged portion whose width in the connecting direction is larger than the opening, and a tip which is located at the tip of the protruding portion and whose width is smaller than the opening A tapered surface that smoothly connects the enlarged portion and the tip end, and a slit that divides the enlarged portion at intervals in the coupling direction,
The plurality of axes extend parallel to one another,
The projection and the recessed groove are provided with a coupling structure in which the part is fitted by moving in the axial direction.

また、本発明によれば、互いの端面を突き合わせて結合する２つの部品を準備し、
２つの前記部品の結合部に、互いに対向して同軸上に位置する突起部と凹溝とを該結合部に沿って互いに間隔を隔てて複数設け、複数の前記軸は、互いに平行に延びるものであり、
前記結合部から前記軸に沿って窪ませ、前記結合部に開口する開口部の奥側に拡大溝部を設け、
前記結合部から前記軸に沿って突出するように前記突起部を設け、該突起部に前記結合部が延びる結合方向における幅が前記開口部より大きい拡大部と、前記突起部の先端に位置し前記開口部より前記幅が小さい先端部と、前記拡大部と該先端部とを滑らかに繋ぐテーパ面と、前記拡大部を前記結合方向に間隔を隔てて分割するスリットと、を設け、
前記部品を前記軸方向に移動させ前記突起部と前記凹溝とを嵌合させる、結合方法が提供される。 Also, according to the invention, two parts are prepared, which join end faces to each other and join them,
A plurality of projections and recesses, which are coaxially located opposite to each other, are provided in the joint portion of the two parts spaced apart from each other along the joint portion, and the plurality of axes extend parallel to each other And
An enlarged groove is provided on the back side of the opening which is recessed from the joint portion along the axis, and is opened in the joint portion,
The projection is provided so as to protrude from the joint along the axis, and the projection is located at an enlarged part larger in width in the joint direction and in the joint direction in which the joint extends, and at the tip of the projection A distal end portion having a width smaller than the opening, a tapered surface that smoothly connects the enlarged portion and the distal end portion, and a slit that divides the enlarged portion at intervals in the coupling direction are provided.
A coupling method is provided, in which the part is moved in the axial direction to fit the protrusion and the recessed groove.

上述した本発明によれば、互いに突き合わせる端面の対向する位置に突起部と凹溝があり、突起部がスリットを有するので、端面への凹溝の開口部を通過する際に拡大部がスリット側へ撓み、凹溝の中を軸方向に進むことができる。また、開口部の結合方向の幅が拡大部より小さく、突起部の先端部より大きいため、拡大部が凹溝にロックされ突起部が凹溝から外れなくなる。これにより端面が突き合うように部品を軸方向に移動させるだけで突起部を凹溝に押し込んで嵌合させることができ、２つの部品を結合することができる。それにより結合構造の組み立てにかかる作業時間を短縮することができる。   According to the present invention described above, since the protrusion and the recess are at the opposing position of the end faces abutting each other, and the protrusion has a slit, the enlarged portion is a slit when passing through the opening of the recess to the end It can flex to the side and travel axially in the recess. In addition, since the width of the opening in the connecting direction is smaller than that of the enlarged portion and larger than the tip of the protrusion, the enlarged portion is locked in the recessed groove and the protrusion does not come out of the recessed groove. As a result, only by moving the part in the axial direction so that the end faces abut each other, the projection can be pushed into and fitted in the recessed groove, and the two parts can be coupled. As a result, the working time required for assembling the coupling structure can be shortened.

It is. In the following description, the direction in which the coupling portion 8 of the end face 3 extends is taken as a coupling direction 24.
In this figure, 15 is a first end face, 16 is a second end face, 19 is a thickness direction, 20 is a first sliding face, 21 is a base portion, and 22 is a second sliding face. The thickness direction 19 is a direction orthogonal to the axial direction and the coupling direction 24.
The material of the part 2 may be metal, synthetic resin, or the like.

以下の説明において、部品２の厚さ方向１９における一方を表面７とし、他方を裏面２５とする。
端面３は、厚さ方向１９における一方側の第１端面１５と、他方側の第２端面１６と、を有する。突起部５及び凹溝６は、第１端面１５に設けられ、結合部８から軸４に沿って窪む。凹溝６は、突起部５に対向する位置に設けられる。
また凹溝６は、結合部８に開口する開口部３１と、開口部３１の奥側に位置し結合部８が延びる結合方向２４における幅が開口部３１より大きい拡大溝部３２と、を有する。
さらに凹溝６は、内側面２３から結合方向２４における外方両側に向けて窪む窪み３４を有していることが好ましい。凹溝６の内側面２３とは、凹溝６の底面６ａから厚さ方向１９に延びる面である。
軸方向と結合方向２４とに直交する厚さ方向１９に延びる窪み３４は、図２（Ｃ）の窪み３４ａに示すように拡大溝部３２に設けられていてもよく、図２（Ｃ）の窪み３４ｂに示すように開口部３１と拡大溝部３２の間に設けられていてもよい。 In the following description, one of the parts 2 in the thickness direction 19 is referred to as the front surface 7, and the other is referred to as the back surface 25.
The end face 3 has a first end face 15 on one side in the thickness direction 19 and a second end face 16 on the other side. The protrusion 5 and the recessed groove 6 are provided on the first end surface 15 and are recessed from the coupling portion 8 along the axis 4. The recessed groove 6 is provided at a position facing the protrusion 5.
The recessed groove 6 has an opening 31 opened to the connecting portion 8 and an enlarged groove 32 located at the back side of the opening 31 and having a width in the connecting direction 24 in which the connecting portion 8 extends is larger than the opening 31.
Furthermore, it is preferable that the recessed groove 6 have a recess 34 recessed from the inner surface 23 toward both outward sides in the coupling direction 24. The inner side surface 23 of the recessed groove 6 is a surface extending in the thickness direction 19 from the bottom surface 6 a of the recessed groove 6.
The recess 34 extending in the thickness direction 19 orthogonal to the axial direction and the coupling direction 24 may be provided in the enlarged groove portion 32 as shown in the recess 34 a of FIG. As shown to 34b, you may be provided between the opening part 31 and the expansion groove part 32. FIG.

第２摺動面２２は、軸方向及び結合方向２４に平行に延び、凹溝６の底面６ａを含む面である。第１摺動面２０は、部品２が嵌合したときに第２摺動面２２に接する軸方向及び結合方向２４に平行に延びる面である。
例えば図１、図２の例の場合、突起部５と凹溝６は、第１端面１５に設けられている。この場合、突起部５が第１端面１５にあるときの第１摺動面２０は、軸方向及び結合方向２４に平行に延び、突起部５の第２端面側の面を含む面である。
例えば突起部５が第２端面１６にあるのであれば、突起部５の第１端面側の面を含む面が第１摺動面２０となる。
第１摺動面２０と第２摺動面２２は、軸方向と結合方向２４に平行に延びていれば、平面でもよく曲面でもよい。 The second sliding surface 22 is a surface that extends in parallel with the axial direction and the coupling direction 24 and includes the bottom surface 6 a of the recessed groove 6. The first sliding surface 20 is a surface extending parallel to the axial direction and the coupling direction 24 in contact with the second sliding surface 22 when the component 2 is fitted.
For example, in the case of the example of FIG. 1, FIG. 2, the protrusion part 5 and the ditch | groove 6 are provided in the 1st end surface 15. As shown in FIG. In this case, the first sliding surface 20 when the protrusion 5 is at the first end surface 15 is a surface that extends parallel to the axial direction and the coupling direction 24 and includes the surface on the second end surface side of the protrusion 5.
For example, if the projection 5 is on the second end face 16, the surface including the surface on the first end face side of the projection 5 is the first sliding surface 20.
The first sliding surface 20 and the second sliding surface 22 may be flat or curved as long as they extend in parallel with the axial direction and the coupling direction 24.

第２部品２Ｂは、第２端面１６に土台部２１を有する。
土台部２１は、第１端面１５より軸方向における外方（軸上に２つの部品２を並べたときの第１部品側）へ延びている。２つの部品２が結合するときに、土台部２１の凹溝側の第２摺動面２２が突起部５の第１摺動面２０と平行に軸方向に延びる。 The second part 2 B has a base portion 21 at the second end face 16.
The base portion 21 extends outward in the axial direction from the first end surface 15 (on the side of the first component when the two components 2 are arranged on the shaft). When the two parts 2 are joined, the second sliding surface 22 on the concave groove side of the base portion 21 extends in the axial direction in parallel with the first sliding surface 20 of the projection 5.

第２部品２Ｂは、土台部２１を有することにより、第２摺動面２２が第１摺動面２０をガイドして、部品２を正確に軸方向に移動させることができる。このとき、突起部５は、第１摺動面２０が第２摺動面上を摺動することにより、第２摺動面２２にガイドされて凹溝６に嵌合する。
また第２摺動面２２が第１摺動面２０と接し、２つの部品２の第２端面１６同士も接するので、土台部２１を有することにより、結合構造１が結合部８で軸方向に折れるのを防ぐことができる。 The second part 2B includes the base portion 21 so that the second sliding surface 22 guides the first sliding surface 20, and the part 2 can be accurately moved in the axial direction. At this time, when the first sliding surface 20 slides on the second sliding surface, the protrusion 5 is guided by the second sliding surface 22 and fitted in the recessed groove 6.
Further, since the second sliding surface 22 contacts the first sliding surface 20 and the second end surfaces 16 of the two components 2 also contacts each other, the joint structure 1 is axially formed at the joint portion 8 by having the base portion 21. You can prevent it from breaking.

結合方向２４において突起部５と同じ位置にある第２端面１６は、土台部２１が第１部品２Ａ側へ突出した分、軸方向において突起部５の根元１７よりも反先端側に位置する。   The second end face 16 located at the same position as the protrusion 5 in the coupling direction 24 is located on the opposite end side of the root 17 of the protrusion 5 in the axial direction because the base portion 21 protrudes toward the first component 2A.

第１部品２Ａは、図２（Ｂ）に示すように第１端面１５に突起部５を有する。
突起部５は、結合部８（第１端面１５）から軸４に沿って突出する突起である。突起部５の形状は、突起部５を凹溝６に差し込んだ状態で完全に嵌合するまで軸方向に部品２を移動し、嵌合が外れないのであればどのような形状であってもよい。突起部５は、弾性部材で構成される。弾性部材は、例えばアルミニウム等の金属や、ＣＦＲＰ等の合成樹脂である。 The first component 2A has a protrusion 5 on the first end face 15 as shown in FIG. 2 (B).
The protrusion 5 is a protrusion that protrudes along the shaft 4 from the coupling portion 8 (first end surface 15). The shape of the projection 5 is such that the part 2 is moved in the axial direction until the projection 5 is completely fitted in the state where the projection 5 is inserted into the recessed groove 6, and the form does not come off Good. The protrusion 5 is formed of an elastic member. The elastic member is, for example, a metal such as aluminum or a synthetic resin such as CFRP.

（突起部５の第１実施例）
図１、図２に示すように本実施例の第１部品２Ａの突起部５は、頚部９、拡大部１０、先端部１２、スリット１１、テーパ面３３を有する。また本実施形態の結合構造１は、スリット１１に嵌合する栓部材１３を備えることが好ましい。 (First embodiment of the protrusion 5)
As shown in FIGS. 1 and 2, the projection 5 of the first component 2A of this embodiment has a neck 9, an enlarged portion 10, a tip 12, a slit 11, and a tapered surface 33. Moreover, it is preferable that the coupling structure 1 of the present embodiment includes the plug member 13 fitted to the slit 11.

突起部５の頚部９は、端面３から軸方向における外方（軸上に２つの部品２を並べたときの第２部品側）へ延びる。
頚部９よりも突起部５の先端側には、拡大部１０が設けられている。拡大部１０は、結合方向２４における幅が開口部３１より大きく設けられている。例えばこの実施例の突起部５の拡大部１０は、頚部９から、結合方向２４の外方に向けて延びる。拡大部１０は、図２では略三角形であるが、これに限らない。この場合、突起部５の根元側の拡大部１０の端面は、結合方向２４に延びている。
しかし拡大部１０の形状はこれに限らない。例えば拡大部１０は例えば半円形状などでもよく、その他の形状でもよい。 The neck portion 9 of the protrusion 5 extends outward in the axial direction from the end surface 3 (the second component side when the two components 2 are aligned on the shaft).
An enlarged portion 10 is provided on the tip end side of the protrusion 5 with respect to the neck portion 9. The enlarged portion 10 is provided such that the width in the coupling direction 24 is larger than the opening 31. For example, the enlarged portion 10 of the projection 5 of this embodiment extends outward from the neck 9 in the coupling direction 24. The enlargement 10 is substantially triangular in FIG. 2, but is not limited thereto. In this case, the end face of the enlarged portion 10 on the root side of the protrusion 5 extends in the coupling direction 24.
However, the shape of the enlarged portion 10 is not limited to this. For example, the enlarged portion 10 may have, for example, a semicircular shape or other shapes.

先端部１２は、突起部５の先端に位置し、開口部３１より幅が小さく設けられている。
テーパ面３３は、拡大部１０と先端部１２とを滑らかに繋ぐ平面又は曲面である。
これにより突起部５は拡大部１０から先端部１２にかけて、結合方向２４の幅が漸減する。 The distal end portion 12 is located at the distal end of the projection 5 and has a smaller width than the opening 31.
The tapered surface 33 is a flat surface or a curved surface that smoothly connects the enlarged portion 10 and the tip portion 12.
As a result, the width of the coupling direction 24 gradually decreases from the enlarged portion 10 to the tip portion 12.

この構成により、突起部５の外側面形状は、頚部９、拡大部１０、先端部１２で構成された矢印形状となっている。   With this configuration, the outer surface of the projection 5 is in the shape of an arrow constituted by the neck 9, the enlarged portion 10 and the tip 12.

スリット１１は、拡大部１０を結合方向２４に間隔を隔てて分割する。本実施形態のスリット１１は、先端部１２から突起部５の根元１７に向けて延びている。
例えばこの実施例の突起部５のスリット１１は、先端部１２の結合方向中央から軸方向内方へ向けて延びる切れ込みである。スリット１１の結合方向２４における幅は、拡大部１０がスリット側へ撓んだときに突起部５の結合方向２４における幅が凹溝６の結合方向２４における幅より小さくなる大きさである。 The slits 11 divide the enlargements 10 at intervals in the coupling direction 24. The slit 11 in the present embodiment extends from the tip 12 toward the root 17 of the protrusion 5.
For example, the slit 11 of the projection 5 in this embodiment is a notch extending inward in the axial direction from the center of the tip 12 in the coupling direction. The width of the slit 11 in the connecting direction 24 is such that the width of the protrusion 5 in the connecting direction 24 is smaller than the width of the recessed groove 6 in the connecting direction 24 when the enlarged portion 10 is bent toward the slit.

第２部品２Ｂは、図２（Ｃ）に示すようにその第１端面１５から軸方向における第２部品２Ｂの内方に向けて窪む凹溝６を有する。凹溝６は、突起部５の外側面形状と同じ形状に窪むのがよい。突起部５の外側面形状とは、上から見たときの突起部５の輪郭である。
しかしそれに限らず、凹溝６は、突起部５が嵌合でき、突起部５が凹溝６から外れないのであれば、突起部５の外側面形状と異なる形状の溝でもよい。 As shown in FIG. 2C, the second part 2B has a recessed groove 6 which is recessed inward from the first end face 15 in the axial direction of the second part 2B. The recessed groove 6 may be recessed in the same shape as the outer surface shape of the protrusion 5. The outer surface shape of the protrusion 5 is the contour of the protrusion 5 when viewed from above.
However, the present invention is not limited to this, and the groove 6 may be a groove having a shape different from the outer surface shape of the protrusion 5 as long as the protrusion 5 can be fitted and the protrusion 5 does not come off the groove 6.

例えば本実施形態の第２部品２Ｂは、突起部５の外側面形状と同じ矢印形状に窪む凹溝６を有する。   For example, the second component 2 </ b> B of the present embodiment includes the recessed groove 6 recessed in the same arrow shape as the outer surface shape of the protrusion 5.

栓部材１３は、突起部５のスリット１１に嵌る部材である。   The plug member 13 is a member that fits into the slit 11 of the protrusion 5.

図３は、２つの部品２が嵌合するときの第１実施例の突起部５と凹溝６の説明図である。図３（Ａ）から図３（Ｄ）にかけて時間が進行する。
図３（Ａ）に示すように、結合方向２４における幅は、凹溝６の軸方向の外方端部より先端部１２の方が小さいため、先端部１２を凹溝６に挿入できる。 FIG. 3 is an explanatory view of the protrusion 5 and the recessed groove 6 of the first embodiment when the two parts 2 are fitted. The time advances from FIG. 3 (A) to FIG. 3 (D).
As shown in FIG. 3A, the width in the coupling direction 24 is smaller at the tip 12 than at the axially outward end of the groove 6, so the tip 12 can be inserted into the groove 6.

突起部５は、結合方向２４における中央にスリット１１を有し、先端部１２から拡大部１０にかけて結合方向２４における幅が漸増している。そのためそのまま部品２を軸方向へ移動させると、図３（Ｂ）に示すように凹溝６の内側面２３に押されて拡大部１０や頚部９がスリット側へ撓む。それにより突起部５の結合方向２４における幅が凹溝６の開口部３１の結合方向２４における幅より小さくなるため突起部５が凹溝６の中へ進行できる。   The protrusion 5 has a slit 11 at the center in the coupling direction 24, and the width in the coupling direction 24 gradually increases from the tip 12 to the enlarged portion 10. Therefore, when the component 2 is moved in the axial direction as it is, it is pushed by the inner side surface 23 of the recessed groove 6 as shown in FIG. 3B, and the enlarged portion 10 and the neck 9 bend to the slit side. Thus, the width of the protrusion 5 in the connecting direction 24 is smaller than the width in the connecting direction 24 of the opening 31 of the recessed groove 6 so that the protruding portion 5 can advance into the recessed groove 6.

凹溝６は、突起部５の外側面形状と同じ矢印形状に設けられている。つまり、凹溝６は、頚部９が嵌る係止部２９と、拡大部１０が嵌る拡大溝部３２を有する。
係止部２９は、軸方向において凹溝６に嵌合した拡大部１０と端面３との間に位置する。
先端部１２が凹溝６の最奥まで到達すると、図３（Ｃ）のように拡大溝部３２で突起部５の拡大部１０が結合方向２４に広がる。これにより、拡大部１０の軸方向における第１部品側に、係止部２９が位置するため、第１部品２Ａが反第２部品側へ軸方向に移動できなくなる。
これにより突起部５の凹溝６への嵌合が完了する。 The recessed groove 6 is provided in the same arrow shape as the outer surface shape of the protrusion 5. That is, the recessed groove 6 has a locking portion 29 in which the neck portion 9 is fitted and an enlarged groove portion 32 in which the enlarged portion 10 is fitted.
The locking portion 29 is located between the enlarged portion 10 fitted in the recessed groove 6 in the axial direction and the end surface 3.
When the tip end portion 12 reaches the deepest end of the recessed groove 6, as shown in FIG. 3C, the enlarged portion 10 of the protrusion 5 spreads in the coupling direction 24 in the enlarged groove portion 32. As a result, since the locking portion 29 is positioned on the first component side in the axial direction of the enlarged portion 10, the first component 2A can not be moved in the axial direction toward the second component side.
Thus, the fitting of the protrusion 5 into the recessed groove 6 is completed.

次に、図３（Ｄ）に示すように、スリット１１に栓部材１３を嵌める。これにより突起部５の拡大部１０がスリット側へ動くのを防ぐため、２つの部品２の結合が外れるのを防ぐことができる。   Next, as shown in FIG. 3D, the plug member 13 is fitted in the slit 11. This prevents the enlarged portion 10 of the projection 5 from moving to the slit side, thereby preventing the two parts 2 from being disconnected.

（突起部５の第２実施例）
図４は、２つの部品２が嵌合するときの第２実施例の突起部５と凹溝６の説明図である。図４（Ａ）から図４（Ｄ）にかけて時間が進行する。
図４に示すように突起部５のスリット１１は、拡大部１０が結合方向２４に移動可能なのであれば、先端部１２に開口していなくてもよい。この場合、拡大部１０が係止部２９を通過するときに図４（Ｂ）のようにスリット１１が結合方向２４に一旦つぶれ、係止部２９を過ぎてから、拡大溝部３２で部品２の剛性により元の形状に戻る。
その他の本実施例の突起部５の構成と効果は、第１実施例と同様である。 (Second embodiment of the protrusion 5)
FIG. 4 is an explanatory view of the protrusion 5 and the concave groove 6 of the second embodiment when two parts 2 are fitted. The time advances from FIG. 4 (A) to FIG. 4 (D).
As shown in FIG. 4, the slit 11 of the projection 5 may not be open at the tip 12 as long as the enlarged part 10 is movable in the coupling direction 24. In this case, when the enlarged portion 10 passes through the locking portion 29, as shown in FIG. 4B, the slit 11 once collapses in the coupling direction 24 and passes the locking portion 29. The stiffness returns to the original shape.
The configuration and effects of the other protrusions 5 of the present embodiment are the same as those of the first embodiment.

本実施形態の結合構造１は、この構成により、部品２を軸方向に移動することにより、図２（Ａ）に示すように突起部５が凹溝６に嵌合し、部品２を結合させることができる。
また、この構成により、軸方向以外の方向に部品２が移動するのを防ぐことができる。 According to this configuration, in the coupling structure 1 of the present embodiment, when the component 2 is moved in the axial direction, the projection 5 is fitted in the recessed groove 6 and the component 2 is coupled as shown in FIG. be able to.
Further, this configuration can prevent the component 2 from moving in directions other than the axial direction.

（第２実施形態）
図５は、本発明の第２実施形態の部品２の一部の斜視図である。図５（Ａ）は突起部５と凹溝６を上側にした斜視図、図５（Ｂ）は突起部５と凹溝６を下側にした斜視図、図５（Ｃ）は、２つの部品２を結合したときの斜視図である。 Second Embodiment
FIG. 5 is a perspective view of part of the part 2 of the second embodiment of the present invention. 5 (A) is a perspective view with the protrusion 5 and the recessed groove 6 up, FIG. 5 (B) is a perspective view with the protrusion 5 and the recessed groove 6 down, and FIG. 5 (C) is two It is a perspective view when the components 2 are combined.

本実施形態の２つの部品２は、その両方ともが突起部５と凹溝６の双方を有する点で第１実施形態とは異なり、その他の点で第１実施形態と共通する。一方の部品２の突起部５は他方の部品２の凹溝６に嵌合し、２つの部品２を結合させる。
突起部５と凹溝６は図５のように交互に部品２に設けられていることが好ましいが、それに限らない。土台部２１は、凹溝６の部位のみに設けられていることが好ましい。 The two parts 2 of the present embodiment are different from the first embodiment in that both of them have both the protrusion 5 and the recessed groove 6, and are common to the first embodiment in other points. The projection 5 of one part 2 is fitted in the recess 6 of the other part 2 to couple the two parts 2.
Preferably, the protrusions 5 and the recesses 6 are alternately provided on the component 2 as shown in FIG. It is preferable that the base portion 21 be provided only at the portion of the recessed groove 6.

本実施形態の結合構造１は、この構成により、結合部８にかかる力を２つの部品２へ均等に分散させることができる。
その他の本実施形態の構成と効果は、第１実施形態と同様である。 The coupling structure 1 of this embodiment can distribute the force applied to the coupling portion 8 evenly to the two parts 2 by this configuration.
The other configuration and effects of the present embodiment are the same as those of the first embodiment.

（第３実施形態）
図６は、本発明の第３実施形態の結合構造１の側面図である。図６（Ａ）は、２つの部品２の結合前であり、図６（Ｂ）は、２つの部品２が結合したときの図である。なお、この図は、窪み３４の記載を省略している。 Third Embodiment
FIG. 6 is a side view of the coupling structure 1 according to the third embodiment of the present invention. FIG. 6A is a view before the two parts 2 are joined, and FIG. 6B is a view when the two parts 2 are joined. In the drawing, the description of the depression 34 is omitted.

本実施形態の結合構造１は、ロケットの機体である。この結合構造１は、軸方向に延びる機軸２７を中心とする円筒面２６をもつ部品２を有する。
この円筒面２６が第１実施形態と第２実施形態における表面７に相当する。この実施例において、部品２は、軸方向に延びる中心軸を中心とする円筒部品である。 The combined structure 1 of the present embodiment is a rocket airframe. The coupling structure 1 comprises a part 2 with a cylindrical surface 26 centered on an axially extending axis 27.
The cylindrical surface 26 corresponds to the surface 7 in the first embodiment and the second embodiment. In this embodiment, the part 2 is a cylindrical part centered on an axially extending central axis.

上述したように結合方向２４は、結合部８が延びる方向である。
部品２が円筒面２６を有する円筒部品である場合、結合方向２４は機軸２７を中心とする周方向である。 As described above, the coupling direction 24 is the direction in which the coupling portion 8 extends.
In the case where the part 2 is a cylindrical part having a cylindrical surface 26, the coupling direction 24 is a circumferential direction around the machine axis 27.

本実施形態の第１摺動面２０と第２摺動面２２も機軸２７を中心とする円筒面であることが好ましい。しかしそれに限らず、対向する第１摺動面２０と第２摺動面２２が互いに平行であり、機軸２７に対しても平行であるならば、平面や機軸２７を中心とする円筒面でない曲面であってもよい。   It is preferable that the first sliding surface 20 and the second sliding surface 22 of the present embodiment are also cylindrical surfaces having the machine shaft 27 as a center. However, the invention is not limited thereto, and if the opposing first sliding surface 20 and the second sliding surface 22 are parallel to each other and parallel to the machine axis 27, a plane or a curved surface which is not a cylindrical plane centered on the machine axis 27 It may be

本実施形態は、結合構造１がロケットの機体なので、部品２は金属または合成樹脂によって構成されている。部品２を金属で製造する場合、部品２は、３Ｄプリンターによって作られることが好ましい。しかしそれに限らず、部品２は削り出しによって製造されてもよい。   In the present embodiment, since the coupling structure 1 is a rocket airframe, the component 2 is made of metal or synthetic resin. If part 2 is made of metal, part 2 is preferably made by a 3D printer. However, not limited thereto, the part 2 may be manufactured by cutting.

図７は、スリット１１に栓部材１３を嵌めた結合構造１の説明図である。この図は、窪み３４の記載を省略している。本実施形態の栓部材１３は、以下の第１実施例と第２実施例のいずれであってもよい。   FIG. 7 is an explanatory view of the coupling structure 1 in which the plug member 13 is fitted in the slit 11. In this figure, the description of the depression 34 is omitted. The plug member 13 of this embodiment may be any of the following first and second embodiments.

いずれの栓部材１３であっても、本実施形態の栓部材１３の素材は、部品２の素材と同じものであることが好ましい。栓部材１３は、金属または合成樹脂であってもよく、その他の素材で設けられていてもよい。例えばロケットの機体である結合構造１が金属のときは、栓部材１３は金属であるのがよい。ロケットの機体がＣＦＲＰであるときの栓部材１３はＣＦＲＰであるのが好ましく、ロケットの機体がアルミニウムであるときの栓部材１３はアルミニウムであるのが好ましい。   It is preferable that the raw material of the plug member 13 of this embodiment is the same as the raw material of the components 2 regardless of which plug member 13 is used. The plug member 13 may be metal or synthetic resin, and may be provided by other materials. For example, when the coupling structure 1 which is a rocket body is metal, the plug member 13 may be metal. When the rocket body is CFRP, the plug member 13 is preferably CFRP, and when the rocket body is aluminum, the plug member 13 is preferably aluminum.

（栓部材１３の第１実施例）
図７（Ａ）は、第１実施例の栓部材１３を嵌めた図である。
本実施例の栓部材１３は、図３（Ｄ）の栓部材１３と同様に、凹溝６に嵌った突起部５のスリット１１に嵌る部材である。
スリット１１に栓部材１３を嵌合させるときには、一つ一つスリット１１に栓部材１３を打ち込んでもよい。
本実施形態の結合構造１によれば、１００本以上のボルトが必要であった従来のロケットと同等の大きさのロケットを、例えば１０箇所〜２０箇所のスリット１１に栓部材１３を打ち込むだけで製造することができる。
したがって、たとえ一つ一つのスリット１１に栓部材１３の打ち込み作業をする場合でも、ボルトを１本１本トルク管理していた従来のロケットの製造工程と比べて短時間でロケットを製造できる。 (First Embodiment of Plug Member 13)
FIG. 7A is a view in which the plug member 13 of the first embodiment is fitted.
The plug member 13 of the present embodiment is a member which fits into the slit 11 of the projection 5 fitted in the recessed groove 6 as in the plug member 13 of FIG. 3 (D).
When fitting the plug members 13 into the slits 11, the plug members 13 may be driven into the slits 11 one by one.
According to the coupling structure 1 of the present embodiment, a rocket having the same size as that of a conventional rocket requiring 100 or more bolts is simply driven into the slits 11 of 10 to 20, for example. It can be manufactured.
Therefore, even when the plug members 13 are driven into the slits 11 one by one, the rocket can be manufactured in a short time as compared with the conventional rocket manufacturing process in which torque control of bolts is performed one by one.

（栓部材１３の第２実施例）
図７（Ｂ）は第２実施例の栓部材１３を嵌めるときの図であり、図７（Ｃ）は第２実施例の栓部材１３を嵌めた図である。
図７（Ｂ）に示すように本実施形態の栓部材１３は、可撓性のある板状部材１４に隣り合ったスリット１１の間隔と同じ間隔を隔てて複数配置されている。 (Second Embodiment of Plug Member 13)
FIG. 7B is a view when the plug member 13 of the second embodiment is fitted, and FIG. 7C is a view where the plug member 13 of the second embodiment is fitted.
As shown in FIG. 7B, a plurality of plug members 13 of the present embodiment are disposed at the same intervals as the intervals of the slits 11 adjacent to the flexible plate-like member 14.

この栓部材１３をスリット１１に嵌め込みながら部品２（円筒部品）の円筒面２６に板状部材１４を巻き付け、図７（Ｃ）に示すように、円筒面２６を締め付けるように板状部材１４の両端部を連結させることにより栓部材１３を部品２に固定する。
それにより１個所締めるだけで一度に栓部材１３をスリット１１に嵌め込むことができる。 While inserting this plug member 13 into the slit 11, the plate-like member 14 is wound around the cylindrical surface 26 of the part 2 (cylindrical part), and the plate-like member 14 is tightened as shown in FIG. The plug member 13 is fixed to the component 2 by connecting both ends.
As a result, the plug member 13 can be fitted into the slit 11 at one time only by tightening at one place.

本実施形態の結合構造１は、これらの構成により、部品２を軸方向に移動させるだけで、部品２の端面３の全周に配置された突起部５が凹溝６に一度に嵌合する。
したがって、フランジやボルトを使用する従来の部品２の結合よりも短時間で結合構造１を結合することができる。 The coupling structure 1 of the present embodiment, with these configurations, allows the protrusions 5 disposed on the entire circumference of the end face 3 of the component 2 to be fitted into the recessed groove 6 at a time simply by moving the component 2 in the axial direction. .
Therefore, the coupling structure 1 can be coupled in a shorter time than coupling of conventional parts 2 using flanges and bolts.

またフランジは、ロケットの機体の円筒面２６から外側に突出しているため、ロケットの飛翔時の空力抵抗となるため、ロケットから出来るだけ突起物を排除することが求められている。本発明によりロケットの機体の全周を取り囲むフランジを無くすことができるため、フランジが受けていた空力抵抗を無くした分、ロケットの能力を向上させることができる。
その他の本実施形態の構成と効果は、第１実施形態又は第２実施形態と同様である。 Further, since the flanges project outward from the cylindrical surface 26 of the rocket's airframe, they provide aerodynamic resistance when the rocket travels, and therefore it is required to eliminate as much protrusion as possible from the rocket. According to the present invention, it is possible to eliminate the flange that surrounds the entire circumference of the rocket's airframe, and therefore the ability of the rocket can be improved as much as the aerodynamic resistance that the flange has received is eliminated.
The other configuration and effects of the present embodiment are the same as those of the first embodiment or the second embodiment.

次に本発明の結合方法を説明する。本発明の結合方法は、本発明の結合構造１の製造方法である。
まず、互いの端面３を突き合わせて結合する２つの部品２を準備する。
２つの部品２の結合部８に、互いに対向して同軸上に位置する突起部５と凹溝６とを、結合部８に沿って互いに間隔を隔てて複数設ける。
このとき突起部５と凹溝６の複数の軸４が互いに平行に延びるようにする。 Next, the coupling method of the present invention will be described. The bonding method of the present invention is a method of producing the bonding structure 1 of the present invention.
First, two parts 2 are prepared in which the end faces 3 of each other are butted and joined.
A plurality of projections 5 and concave grooves 6 coaxially located opposite to each other are provided in the joint portion 8 of the two parts 2 at intervals along the joint portion 8.
At this time, the plurality of axes 4 of the projection 5 and the recessed groove 6 are made to extend in parallel with each other.

凹溝６は、結合部８から軸４に沿って窪ませて設ける。また、結合部８に開口する開口部３１の奥側には拡大溝部３２を設ける。
突起部５は、結合部８から軸４に沿って突出するように設ける。突起部５には、上述した拡大部１０、先端部１２、テーパ面３３、スリット１１を設ける。
部品２を金属で製造する場合には、３Ｄプリンターで部品２を製造することが好ましい。しかしそれに限らず、削り出しによって部品２を製造してもよい。 The recessed groove 6 is provided to be recessed along the shaft 4 from the joint portion 8. Further, an enlarged groove portion 32 is provided on the back side of the opening 31 opened to the coupling portion 8.
The protrusion 5 is provided to project along the axis 4 from the joint 8. The protrusion 5 is provided with the above-described enlarged portion 10, the tip 12, the tapered surface 33, and the slit 11.
When the part 2 is made of metal, it is preferable to manufacture the part 2 with a 3D printer. However, the invention is not limited thereto, and the component 2 may be manufactured by cutting.

次に、部品２を軸方向に移動させ、突起部５を凹溝６に嵌合させる。
例えば第３実施形態の場合、図６（Ａ）のように、それぞれの円筒部品（部品２）を軸方向に搬送可能な搬送機２８に部品２を載せる。そして、軸方向に前後するアクチュエータ３０で部品２を軸方向に移動させる。
それにより図６（Ｂ）のように、部品２に設けられている全ての突起部５を一度に凹溝６に嵌合させることができる。これにより２つの円筒部品（部品２）を結合して、ロケットの機体（結合構造１）を結合することができる。 Next, the component 2 is moved in the axial direction, and the protrusion 5 is fitted in the recessed groove 6.
For example, in the case of the third embodiment, as shown in FIG. 6A, the component 2 is placed on the conveyer 28 capable of axially conveying the respective cylindrical components (component 2). Then, the component 2 is moved in the axial direction by the actuator 30 which moves in the axial direction.
As a result, as shown in FIG. 6B, all the projections 5 provided on the component 2 can be fitted into the recessed groove 6 at one time. As a result, the two cylindrical parts (part 2) can be combined to combine the rocket's airframe (coupling structure 1).

次いで、スリット１１に栓部材１３を嵌合させる場合には、スリット１１に第１実施例の栓部材１３を打ち込み、もしくは第２実施例の栓部材１３を打ち込みながら板状部材１４をロケットの機体（結合構造１）に巻き付ける。
これにより、拡大部１０の結合方向２４の動きが抑えられるので、一方の部品２を他方の部品２に固定することができる。このように、本発明の結合方法を使用することにより、容易に結合構造１を製造できる。 Next, when the plug member 13 is fitted in the slit 11, the plate member 14 is inserted into the body of the rocket while driving the plug member 13 of the first embodiment into the slit 11 or driving the plug member 13 of the second embodiment. Wrap around (bond structure 1).
As a result, the movement of the enlarged portion 10 in the coupling direction 24 is suppressed, so that one part 2 can be fixed to the other part 2. Thus, the bonded structure 1 can be easily manufactured by using the bonding method of the present invention.

なお、結合構造１を分解するときは、栓部材１３をスリット１１から取り出し、窪み３４に治具を挿入し、拡大部１０をスリット側へ移動させながら部品２を軸方向へ移動させることにより、一方の部品２を他方の部品２から外すことができる。この治具は、例えばペンチであってもよく、その他の物であってもよい。   When disassembling the coupling structure 1, the plug member 13 is taken out from the slit 11, a jig is inserted into the recess 34, and the component 2 is moved in the axial direction while moving the enlarged portion 10 to the slit side. One part 2 can be removed from the other part 2. The jig may be, for example, a pliers or other item.

上述した本発明によれば、互いに突き合わせる端面３の対向する位置に突起部５と凹溝６があり、突起部５がスリット１１を有するので、端面３への凹溝６の開口部３１を通過する際に拡大部１０がスリット１１側へ撓み、凹溝６の中を軸方向に進むことができる。また、開口部３１の結合方向２４の幅が拡大部１０より小さく、突起部５の先端部１２より大きいため、拡大部１０が凹溝６にロックされ突起部５が凹溝６から外れなくなる。これにより端面３が突き合うように部品２を軸方向に移動させるだけで突起部５を凹溝６に押し込んで嵌合させることができ、２つの部品２を結合することができる。それにより結合構造１の組み立てにかかる作業時間を短縮することができる。   According to the present invention described above, since the protrusion 5 and the recessed groove 6 are provided at opposite positions of the end face 3 abutting each other, and the protrusion 5 has the slit 11, the opening 31 of the recessed groove 6 to the end face 3 is When passing through, the enlarged portion 10 can be bent toward the slit 11 and can axially advance in the recessed groove 6. Further, since the width of the opening 31 in the coupling direction 24 is smaller than the enlarged portion 10 and larger than the tip 12 of the protrusion 5, the enlarged portion 10 is locked in the recessed groove 6 and the protrusion 5 does not come off the recessed groove 6. As a result, only by moving the component 2 in the axial direction so that the end face 3 abuts, the projection 5 can be pushed into and fitted in the recessed groove 6, and the two components 2 can be coupled. As a result, the working time for assembling the coupling structure 1 can be shortened.

なお本発明は上述した実施の形態に限定されず、本発明の要旨を逸脱しない範囲で種々変更を加え得ることは勿論である。   The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the scope of the present invention.
