Description

本発明は、摩擦圧接を利用して金属材料同士を接合する接合方法及びその装置に関するものである。   The present invention relates to a joining method and apparatus for joining metal materials using friction welding.

従来から金属材料の接合方法として摩擦圧接による接合方法が知られている。
この接合方法は、被接合部材同士を突き合わせて、何れか一方を固定し、他の一方を回転させる相対回転運動させ、その接触面に発生する摩擦熱を利用して圧接する方法である。この圧接では、被接合部材の突き合わせ部位が摩擦熱によって所定温度に達し、軟化した状態でさらに互いを押しつけられることで接合される。
また、どちらの被接合部材も回転させない摩擦圧接方法として、2つの被接合部材の間にインサート材を介在させ、被接合部材を非回転状態にし、インサート材を回転状態として各々を接触させ摩擦接合を行なうインサート材を用いる圧接方法も知られている。(例えば、特許文献1参照)
Conventionally, a joining method by friction welding is known as a joining method of metal materials.
This joining method is a method in which members to be joined are brought into contact with each other, one of them is fixed, the other one is rotated relative to each other, and the other member is pressed using frictional heat generated on the contact surface. In this pressure welding, the butted portions of the members to be joined reach a predetermined temperature by frictional heat, and are joined by being pressed against each other in a softened state.
In addition, as a friction welding method in which neither of the members to be joined is rotated, an insert material is interposed between the two members to be joined, the member to be joined is in a non-rotating state, and the insert material is in a rotating state to contact each other and friction welding. There is also known a pressure welding method using an insert material. (For example, see Patent Document 1)

このインサート材を用いる圧接方法は、一対の被接合部材の端部間にインサート材(接合材)を介挿してインサート材の両端面をそれら被接合部材の各端面にそれぞれ対向させ、一対の被接合部材を非回転状態に保持する一方、インサート材を回転させることによって、インサート材の両端部と対応する被接合部材の各端部とを摩擦圧接するものである。
前述のような、インサート材を用いる摩擦接合においては、2つの被接合部材を移動させて、インサート材への接触及び圧接を行なうので、それぞれの被接合部材をインサート材側へ押圧させる押圧手段が必要となる。
In this pressure welding method using an insert material, an insert material (joining material) is inserted between the ends of a pair of members to be joined, and both end surfaces of the insert material are opposed to the end surfaces of the members to be joined, respectively. While holding a joining member in a non-rotating state, by rotating an insert material, friction welding of the both ends of an insert material and each edge part of a to-be-joined member corresponding is carried out.
In the friction welding using the insert material as described above, since the two members to be joined are moved to contact and press the insert material, there is a pressing means for pressing each member to be joined to the insert material side. Necessary.

さらに、特許文献1明細書段落(0019)記載のように「接合材に対する被接合材の軸方向の押圧荷重及び変位量は等しくするのが望ましい」。そのためには、「ロードセル等荷重検知手段、変位センサー等を設けておいて、それらにより荷重検知、変位検知を行ないつつシリンダーによる被接合材の軸方向荷重、変位を制御する」ことが必要となる。   Furthermore, as described in paragraph (0019) of Patent Document 1, it is desirable that the axial pressing load and displacement amount of the materials to be bonded to the bonding material are equal. For that purpose, it is necessary to “provide load detection means such as a load cell, a displacement sensor, etc., and control the axial load and displacement of the material to be joined by the cylinder while performing load detection and displacement detection by them”. .

しかしながら、シリンダーのような押圧手段を2つの被接合材の各々に設ける場合での摩擦圧接に必要な押圧力の大きさは、例えば、直径30mmの鋼材同士を2500rpmで回転させて摩擦圧接させる場合においては、接触により発熱させる工程で28KN(キロニュートン)、圧接接合させる工程で69KN(キロニュートン)程度の押圧力が必要となる。
これらの押圧力を発生させる押圧手段(例えば油圧シリンダ)は大型の装置にならざるを得ない。そのため装置が大型のものとなり、コンパクトな装置とはなりにくい。また、駆動源となる油圧配管も2系統分の配管が必要となり、装置が複雑なものとなる。
However, the magnitude of the pressing force required for friction welding when a pressing means such as a cylinder is provided on each of the two materials to be joined is, for example, when steel materials having a diameter of 30 mm are rotated at 2500 rpm and friction welding is performed. In this case, a pressing force of about 28 KN (kilonewtons) is required in the step of generating heat by contact and 69 KN (kilonewtons) is required in the step of pressure welding.
The pressing means (for example, a hydraulic cylinder) for generating these pressing forces must be a large device. Therefore, the apparatus becomes large and it is difficult to make a compact apparatus. In addition, the hydraulic piping serving as the driving source requires two systems of piping, which complicates the apparatus.

また、センサーなどの検知手段で荷重検知、変位検知を行ないつつ、押圧手段による被接合部材への軸方向荷重、変位を制御するためには、微小量の変位を検知し、移動量を調整することが必要となり、非常にシビアなコントロールを実施する必要がある。さらには、それらの極めて微小量のコントロールを2つの被接合部材の各端面が同じ条件となるように同期させて制御しなければならず、これには複雑なフィードバック制御を行なう必要があり、非常に困難であった。
特開平6−328273号公報
In addition, in order to control the axial load and displacement of the member to be joined by the pressing means while detecting the load and the displacement by a detecting means such as a sensor, a minute amount of displacement is detected and the movement amount is adjusted. It is necessary to implement very severe control. Furthermore, these extremely small amounts of control must be controlled in synchronism so that the end faces of the two members to be joined have the same condition, which requires complicated feedback control, It was difficult.
JP-A-6-328273

したがって、本発明は、インサート材を用いる摩擦圧接接合において、インサート材の両端部と、対応する2つの被接合部材の各端部での接合条件(軸方向の押圧荷重及び変位量)を簡単な構造で同じ条件とし、各接続部の材料強度を一定とすることを目的とする。   Therefore, according to the present invention, in the friction welding using the insert material, the joining conditions (the axial pressing load and the displacement amount) at both ends of the insert material and the respective ends of the two corresponding members to be joined are simplified. The purpose is to keep the same conditions in the structure and to keep the material strength of each connection part constant.

本発明によれば、摩擦圧接を行なう2つの接合面に加わる押圧力が等しくなるので、部材同士の接合状態も等しくなり、2ヶ所の接合部の強度が一定となる。そのため、製品全体の強度が均一となり、製品の品質安定化を実現できる。
また、ひとつの押圧手段を用いて2つの接合面を摩擦圧接するので、押圧手段を複数備えることなく、摩擦圧接装置のコンパクト化が可能となり、装置全体が軽量化でき、構造も簡素化できる。
According to the present invention, since the pressing force applied to the two joining surfaces to be subjected to the friction welding is equal, the joining state of the members is also equal, and the strength of the two joints is constant. For this reason, the strength of the entire product becomes uniform, and the product quality can be stabilized.
In addition, since the two joining surfaces are friction-welded using one pressing means, the friction welding apparatus can be made compact without providing a plurality of pressing means, the entire apparatus can be reduced in weight, and the structure can be simplified.

さらには、ひとつの押圧手段の動きを制御するので、従来のように2つの押圧手段を同じ動きとなるように制御しなくて良くなり、制御の煩雑さや難解さに煩わされることなく簡単容易に押圧手段の制御を行なう事が出来る。   Furthermore, since the movement of one pressing means is controlled, it is not necessary to control the two pressing means so as to have the same movement as in the prior art, and it is easy and easy without being bothered by the complexity and difficulty of control. The pressing means can be controlled.

従来の摩擦圧接装置においては、インサート材把持手段が軸方向で固定されているのでインサート材に加わる2つの押圧力の大きさに差が生じると、インサート材把持手段のインサート把持部分へ押圧力の差分の力が一方側より加わり、両端が固定されたインサート材把持手段に曲げ応力が発生する。この曲げ応力に対向するため、インサート材把持手段は軸方向に高い剛性が必要であった。
しかしながら、本発明の構成によれば、インサート材に加わる2つの押圧力の大きさに差が生じることがないので、インサート材把持手段に曲げ応力が発生することがなくなり、インサート材把持手段を軸方向にコンパクトで薄い構成にすることができる。
In the conventional friction welding apparatus, since the insert material gripping means is fixed in the axial direction, if there is a difference in the magnitude of the two pressing forces applied to the insert material, the pressing force is applied to the insert gripping portion of the insert material gripping means. A differential force is applied from one side, and bending stress is generated in the insert material gripping means fixed at both ends. In order to oppose this bending stress, the insert material gripping means required high rigidity in the axial direction.
However, according to the configuration of the present invention, there is no difference in the magnitude of the two pressing forces applied to the insert material, so that no bending stress is generated in the insert material gripping means, and the insert material gripping means is pivoted. A compact and thin configuration in the direction.

この状態で押圧手段13の油圧シリンダーを伸長させて第二接合材把持手段15を回転軸芯方向でインサート材3へ向けて押し出す。油圧シリンダーで押された第二接合材把持手段15は、基台4に設けられた基台側ガイド部材26に案内されて回転軸芯Z方向でインサート材3へ向けて摺動する。
この第二接合材把持手段15の移動により、第二接合材2の端面がインサート材3の端面に接触する。
First, the first bonding material 1, the insert material 3, and the second bonding material 2 are not in contact with each other and are held by the respective holding means in a separated state.
In this state, the hydraulic cylinder of the pressing means 13 is extended to push the second bonding material gripping means 15 toward the insert material 3 in the rotation axis direction. The second bonding material gripping means 15 pushed by the hydraulic cylinder is guided by the base side guide member 26 provided on the base 4 and slides toward the insert material 3 in the direction of the rotation axis Z.
By the movement of the second bonding material gripping means 15, the end surface of the second bonding material 2 comes into contact with the end surface of the insert material 3.

このとき、第二接合材2が非回転状態で固定され、インサート材3が回転状態であるため、接触している第二接合材2の端面とインサート材3の端面が摩擦をおこし発熱する。
さらに油圧シリンダーの伸長が継続されると、第二接合材把持手段15を押す押圧手段13の押圧力は、当接する第二接合材2とインサート材3を通じてインサート材把持手段16に伝達される。インサート材把持手段16は第二接合材把持手段15と同じく、基台側ガイド部材26を介して回転軸芯Z方向に固定されず摺動自在に基台4へ設けられているので、押圧手段13の押圧力は第二接合材2とインサート材3を圧接することなく、第二接合材把持手段15とインサート材把持手段16を摺動させる力として作用する。
At this time, since the second bonding material 2 is fixed in a non-rotating state and the insert material 3 is in a rotating state, the end surface of the second bonding material 2 that is in contact with the end surface of the insert material 3 generates friction and generates heat.
When the extension of the hydraulic cylinder is continued, the pressing force of the pressing means 13 that presses the second bonding material gripping means 15 is transmitted to the insert material gripping means 16 through the second bonding material 2 and the insert material 3 that are in contact with each other. Like the second bonding material gripping means 15, the insert material gripping means 16 is provided on the base 4 so as to be slidable without being fixed in the direction of the rotation axis Z through the base side guide member 26. The pressing force 13 acts as a force for sliding the second bonding material gripping means 15 and the insert material gripping means 16 without pressing the second bonding material 2 and the insert material 3 together.

第二接合材2で押されたインサート材把持手段16は、基台4に設けられた基台側ガイド部材26に沿って軸方向の第一接合材1へ向けて摺動する。
このとき第二接合材把持手段15とインサート材把持手段16は一体となって摺動するので、第二接合材2の端面とインサート材3の端面が接触している状態で、インサート材3の端面が第一接合材1の端面に接触する。
その際、インサート材3が回転状態であり、第一接合材1が非回転状態で固定されているため、接触しているインサート材3の端面と第一接合材1の端面が摩擦をおこし発熱する。
The insert material gripping means 16 pushed by the second bonding material 2 slides toward the first bonding material 1 in the axial direction along the base side guide member 26 provided on the base 4.
At this time, the second bonding material gripping means 15 and the insert material gripping means 16 slide together, so that the end surface of the second bonding material 2 and the end surface of the insert material 3 are in contact with each other. The end surface is in contact with the end surface of the first bonding material 1.
At that time, since the insert material 3 is in a rotating state and the first bonding material 1 is fixed in a non-rotating state, the end surface of the contacting insert material 3 and the end surface of the first bonding material 1 cause friction to generate heat. To do.

インサート材3両端の接触面で第一接合材1と第二接合材2が接触した状態でさらに押圧手段13が押圧しつづけると、第一接合材把持手段14は回転軸芯方向で基台4に対して固定されているため、押圧手段13の押圧力により第二接合材2がインサート材3に押し付けられ、また同様にインサート材3が第一接合材1に押し付けられて夫々の接触面で摩擦圧接が行なわれ、インサート材3の両端に第一接合材1と第二接合材2が接合される。
このとき、押圧手段13の押圧力はインサート材3と第一接合材1との接触面(ア)とインサート材3と第二接合材2との接触面(イ)に同時に同じ力で加わるので、接触面(ア)と接触面(イ)は同じ条件で摩擦圧接が行われることとなり、インサート材3と第一接合材1、及びインサート材3と第二接合材2は同じ接合強度で接合することができる。
If the pressing means 13 continues to press while the first bonding material 1 and the second bonding material 2 are in contact with each other at the contact surfaces at both ends of the insert material 3, the first bonding material gripping means 14 moves in the direction of the rotation axis. Therefore, the second bonding material 2 is pressed against the insert material 3 by the pressing force of the pressing means 13, and the insert material 3 is pressed against the first bonding material 1 in the same manner. Friction welding is performed, and the first bonding material 1 and the second bonding material 2 are bonded to both ends of the insert material 3.
At this time, the pressing force of the pressing means 13 is simultaneously applied to the contact surface (a) between the insert material 3 and the first bonding material 1 and the contact surface (b) between the insert material 3 and the second bonding material 2 with the same force. The contact surface (A) and the contact surface (A) are subjected to friction welding under the same conditions, and the insert material 3 and the first bonding material 1 and the insert material 3 and the second bonding material 2 are bonded with the same bonding strength. can do.

本発明の作用説明図を図2に示す。
図2(a)において、第一接合材1とインサート材3と第二接合材2は互いに離れて設置されている。第一接合材1は非回転状態で回転軸芯Z方向では固定されており、インサート材3は回転状態である。第二接合材2は非回転状態で押圧力Pを加えられ、回転軸芯Z方向でインサート材3に向けて摺動される。
図2(b)において、摺動された第二接合材2は回転するインサート材3に接触し、インサート材3と第二接合材2の接触面(イ)には回転するインサート材3と非回転状態の第二接合材2の接触により摩擦熱が発生している。
さらに、押圧力Pでインサート材3が回転軸芯Z方向で第一接合材に向けて押されると、インサート材3は回転軸芯Z方向で摺動自在になされているので、押圧力が加えられても、第二接合材2とインサート材3は圧接されずに接触状態のまま一体となって回転軸芯Z方向で第一接合材に向けて摺動を開始する。
FIG. 2 is a diagram for explaining the operation of the present invention.
In FIG. 2A, the first bonding material 1, the insert material 3, and the second bonding material 2 are installed apart from each other. The first bonding material 1 is fixed in the rotation axis Z direction in a non-rotating state, and the insert material 3 is in a rotating state. The second bonding material 2 is applied with a pressing force P in a non-rotating state, and is slid toward the insert material 3 in the direction of the rotation axis Z.
In FIG. 2 (b), the slid second joining material 2 contacts the rotating insert material 3, and the contact surface (b) between the insert material 3 and the second joining material 2 does not contact the rotating insert material 3. Friction heat is generated by the contact of the rotating second bonding material 2.
Further, when the insert material 3 is pushed toward the first bonding material in the direction of the rotation axis Z by the pressing force P, the insert material 3 is slidable in the direction of the rotation axis Z, so that the pressing force is applied. Even if the second bonding material 2 and the insert material 3 are in contact with each other without being pressed against each other, the second bonding material 2 and the insert material 3 start to slide toward the first bonding material in the direction of the rotation axis Z.

図2(c)においては、摺動された第二接合材2とインサート材3は第一接合材1に接触する。この状態では第一接合材1とインサート材3の接触面(ア)と、インサート材3と第二接合材2の接触面(イ)は接触状態となり、摩擦熱が発生する。
図2(d)に示すように、さらに押圧力Pが加えられ続ける、またはより大きな押圧力が加えられると、第一接合材1は回転軸芯Z方向で移動できずに固定されているため、接触面(ア)、接触面(イ)に押圧力に対して反力が生じ、圧接作用が発生し、摩擦圧接が行なわれる。
In FIG. 2C, the slid second bonding material 2 and the insert material 3 are in contact with the first bonding material 1. In this state, the contact surface (a) of the first bonding material 1 and the insert material 3 and the contact surface (b) of the insert material 3 and the second bonding material 2 are in a contact state, and frictional heat is generated.
As shown in FIG. 2D, when the pressing force P continues to be applied or a larger pressing force is applied, the first bonding material 1 is fixed without being able to move in the direction of the rotation axis Z. A reaction force is generated against the pressing force on the contact surface (A) and the contact surface (A), a pressing action is generated, and a friction welding is performed.

本発明の摩擦圧接では、インサート材把持手段16と第二接合材把持手段15を回転軸芯Z方向で摺動自在とすることで、押圧手段13の押圧力がインサート材3を介してインサート材把持手段16の回転軸芯Z方向での摺動のための作用力となる。
そのため、第二接合材2がインサート材3に当接する際にはお互いが圧接されることなく、第二接合材把持手段15とインサート材把持手段16が一体となって回転軸芯Z方向に摺動される。
In the friction welding of the present invention, by making the insert material gripping means 16 and the second bonding material gripping means 15 slidable in the direction of the rotation axis Z, the pressing force of the pressing means 13 is inserted through the insert material 3 into the insert material. This is an action force for sliding of the gripping means 16 in the direction of the rotation axis Z.
Therefore, when the second bonding material 2 contacts the insert material 3, the second bonding material gripping means 15 and the insert material gripping means 16 are integrally slid in the rotation axis Z direction without being pressed against each other. Moved.

その後、接触状態で一体となって回転軸芯Z方向で移動する第二接合材2とインサート材3が、回転軸芯Z方向で固定された第一接合材1に当接することで、押圧力が圧接力として第一接合材1とインサート材3の接触面(ア)とインサート材3と第二接合材2の接触面(イ)に作用し、材料の摩擦圧接が行なわれる。
これにより、ひとつの押圧手段13を用いて、第一接接合材1とインサート材3及び、インサート材3と第二接合材2の接合を同時に同じ接合条件で行なうことが、制御やセンサーを用いることなく可能となる。
After that, the second bonding material 2 and the insert material 3 that move together in the contact state in the rotation axis Z direction come into contact with the first bonding material 1 fixed in the rotation axis Z direction. Acts as a pressure contact force on the contact surface (a) of the first bonding material 1 and the insert material 3 and the contact surface (b) of the insert material 3 and the second bonding material 2, and friction welding of the materials is performed.
Thereby, it is possible to use a single pressing means 13 to simultaneously bond the first bonding material 1 and the insert material 3 and the insert material 3 and the second bonding material 2 under the same bonding conditions, using a control and a sensor. It becomes possible without.

次に本発明の他の実施例を説明する。
図3は本発明を実施するのに好適な装置の別の例での側面図を示している。図3中のX−X矢視図を図4に示している。
前記の実施例では、図1に記載のように第二接合材把持手段15とインサート材把持手段16を摺動自在に係合させるスライドガイド手段12の基台側ガイド部材25として、基台4にガイドレールを設け、そのガイドレールに第二接合材把持手段側スライド部材23とインサート材把持手段23を係合させて第二接合材把持手段15とインサート材把持手段16をガイドレール上で走行自在となし、摺動自在とする例を示している。
Next, another embodiment of the present invention will be described.
FIG. 3 shows a side view of another example of an apparatus suitable for practicing the present invention. The XX arrow line view in FIG. 3 is shown in FIG.
In the above embodiment, as shown in FIG. 1, the base 4 is used as the base side guide member 25 of the slide guide means 12 that slidably engages the second bonding material gripping means 15 and the insert material gripping means 16. The guide rail is provided with a slide member 23 and the insert material gripping means 23 engaged with the guide rail so that the second joint material gripping means 15 and the insert material gripping means 16 travel on the guide rail. An example of free and non-slidable is shown.

しかしながら、スライドガイド手段12は前述の例に限るものではなく、例えば図3、図4に示すような本発明の他の実施例では基台側ガイド部材25として基台4へ摺動容易なガイド軸25aを基台4の回転軸芯方向に平行に2本設け、このガイド軸25aに貫通させて第二接合材把持手段15とインサート材把持手段16を摺動自在に配設して、軸方向にスライド自在とする。
この構成では、ガイド軸25aに係合する第二接合材把持手段側スライド部材23とインサート材把持手段側スライド部材24としてガイド軸25aとの当接面にベアリング部材や潤滑剤含有素材をはめ込んでガイド軸25aに対して摺動し易くすれば、第二接合材把持手段15とインサート材把持手段16の摺動がより容易となり、押圧手段13の押圧力の軽減化が可能となる。
However, the slide guide means 12 is not limited to the above example. For example, in another embodiment of the present invention as shown in FIGS. 3 and 4, a guide that can be easily slid to the base 4 as the base side guide member 25. Two shafts 25a are provided parallel to the direction of the axis of rotation of the base 4, and the second bonding material gripping means 15 and the insert material gripping means 16 are slidably disposed through the guide shaft 25a. It is slidable in the direction.
In this configuration, a bearing member and a lubricant-containing material are fitted on the contact surfaces of the guide shaft 25a as the second bonding material gripping means side slide member 23 and the insert material gripping means side slide member 24 that are engaged with the guide shaft 25a. If the sliding with respect to the guide shaft 25a is facilitated, the sliding of the second bonding material gripping means 15 and the insert material gripping means 16 becomes easier, and the pressing force of the pressing means 13 can be reduced.

また、押圧手段13も前記実施例では油圧シリンダーを用いて示しているが、これに限るものではなく、空圧シリンダーやジャッキなど一般的に押圧力を発生する構成であればよい。   In addition, the pressing means 13 is shown as a hydraulic cylinder in the above embodiment, but is not limited to this, and any structure that generally generates a pressing force such as a pneumatic cylinder or a jack may be used.

また、図3中のY−Y矢視図である図5に示されるように、駆動源5の回転を伝達する構成として、駆動側プーリー7と従動側プーリー8にベルト9を懸けることで回転の伝達する例を示しているが、本発明はこれに限定するものではなく一般的に用いられる回転力を伝達する構成であればよい。例えば中間歯車を介在させて駆動側歯車の回転を従動側歯車に伝達する構成としたり、中間歯車を介することなく駆動側歯車と従動側歯車を直接かみ合わせることで駆動源5の回転をインサート材3に伝達することもできる。   Further, as shown in FIG. 5, which is a view taken along arrow YY in FIG. 3, as a configuration for transmitting the rotation of the drive source 5, the belt 9 is hung on the driving pulley 7 and the driven pulley 8 to rotate. However, the present invention is not limited to this, and any configuration that transmits a generally used rotational force may be used. For example, the rotation of the drive source 5 can be transmitted to the driven gear via an intermediate gear, or the drive source 5 can be directly engaged with the driven gear without using the intermediate gear. 3 can also be transmitted.

図4中のA−A矢視図である図6にインサート材把持手段16と回転軸6と駆動側プーリー7の断面図を示す。
インサート材3を回転させる駆動源5の設置位置においては、前記実施例では、駆動源5を基台4に設置しているが、インサート材把持手段16の回転軸芯Z方向の摺動に際し回転力の伝達を可能とするため、回転軸6と駆動側プーリー7をスプライン構造とし、インサート材把持手段16の摺動と共に駆動側プーリー7も回転軸6を摺動可能としている例を示している。
しかしながら本発明の他の実施例としては、駆動源5をインサート材把持手段16に設置し、インサート材把持手段16と駆動源5を一体となして回転軸芯Z方向に摺動可能とする。これにより回転軸6と駆動側プーリー7をスプライン構造とすることなく駆動源5の回転を伝達でき、回転力を伝達する部分である回転軸6と駆動側プーリー7の構造をより簡単な構造とすることができる。
FIG. 6, which is a view taken along the line AA in FIG. 4, shows a cross-sectional view of the insert material gripping means 16, the rotating shaft 6, and the driving pulley 7.
In the above-described embodiment, the drive source 5 is installed on the base 4 at the installation position of the drive source 5 for rotating the insert material 3, but rotates when the insert material gripping means 16 slides in the rotation axis Z direction. In order to enable transmission of force, the rotating shaft 6 and the driving pulley 7 have a spline structure, and the driving pulley 7 can also slide the rotating shaft 6 as the insert material gripping means 16 slides. .
However, as another embodiment of the present invention, the drive source 5 is installed in the insert material gripping means 16, and the insert material gripping means 16 and the drive source 5 are integrated so as to be slidable in the rotation axis Z direction. Accordingly, the rotation of the drive source 5 can be transmitted without the spline structure of the rotating shaft 6 and the driving pulley 7, and the structure of the rotating shaft 6 and the driving pulley 7, which is a part for transmitting the rotational force, can be simplified. can do.

図6中のB−B矢視図である図7にインサート材把持手段16のインサート材3を掴むインサート材把持部26の実施例の詳細図を示す。図7に示すようにインサート材3は2枚の板状の把持プレート17に挟まれて把持される。
略半円形状の把持プレート17の中心位置に半円形の穴を設け、2枚の把持プレート17a、17bで形成される円形の穴にインサート材3が挟まれることでインサート材3が把持されるようになされている。
2枚の把持プレート17a、17bの図7中上方の一端側には対向する突起形状の凸部18が設けられ、先細り状に傾斜面27が設けられている。
A detailed view of an embodiment of the insert material gripping portion 26 that grips the insert material 3 of the insert material gripping means 16 is shown in FIG. As shown in FIG. 7, the insert material 3 is sandwiched and gripped by two plate-like gripping plates 17.
A semicircular hole is provided at the center position of the substantially semicircular gripping plate 17, and the insert member 3 is gripped by the insert member 3 being sandwiched between the circular holes formed by the two gripping plates 17a and 17b. It is made like that.
Opposite protrusion-shaped convex portions 18 are provided on one end side of the upper side of the two grip plates 17a and 17b in FIG. 7, and an inclined surface 27 is provided in a tapered shape.

前記把持プレート17a、17bの凸部18の傾斜面27に係合する凹部を有する狭持部材19が2枚の把持プレート17を挟みつけるように設けられている。
この狭持部材19が図7中下方の把持プレート17側に移動することで2枚の把持プレート17a、17bは中央に寄せられ、インサート材3を挟み込むようになされている。
図7中のC−C矢視図であるインサート材把持部26の部分断面図を図8に示す。
狭持部材19の図8中上方にはテーパー面28が備えられており、このテーパー面28に当接してテーパー駒21が設けられている。このテーパー駒21には押し込みピン20が回転自在に取り付けられている。この押し込みピン20は、押さえプレート22にネジ構造で螺合されている。
A holding member 19 having a concave portion that engages with the inclined surface 27 of the convex portion 18 of the grip plates 17a and 17b is provided so as to sandwich the two grip plates 17 therebetween.
When the holding member 19 moves to the lower gripping plate 17 side in FIG. 7, the two gripping plates 17 a and 17 b are moved to the center so that the insert material 3 is sandwiched therebetween.
FIG. 8 shows a partial cross-sectional view of the insert material gripping portion 26 as viewed in the direction of arrows CC in FIG.
A tapered surface 28 is provided above the holding member 19 in FIG. 8, and a tapered piece 21 is provided in contact with the tapered surface 28. A push pin 20 is rotatably attached to the taper piece 21. The pushing pin 20 is screwed to the holding plate 22 with a screw structure.

図8において、押し込みピン20が押さえプレート22にねじ込まれると、図8中左方に押し込みピン20が移動し、テーパー面28を介して押し込みピン20が狭持部材19を図8中下方の把持プレート17側に押し込む。
それにより狭持部材19が図7中下方の把持プレート17側に移動し、傾斜面27を押圧して2枚の把持プレート17a、17bが中央に寄せられ、2枚の把持プレート17a、17bによりインサート材3は挟み込まれて把持される。
In FIG. 8, when the push pin 20 is screwed into the holding plate 22, the push pin 20 moves to the left in FIG. 8, and the push pin 20 grips the holding member 19 through the tapered surface 28 in the lower part of FIG. 8. Push in the plate 17 side.
As a result, the holding member 19 moves to the lower gripping plate 17 side in FIG. 7 and presses the inclined surface 27 so that the two gripping plates 17a and 17b are moved to the center, and the two gripping plates 17a and 17b The insert material 3 is sandwiched and gripped.

インサート材把持手段16のインサート材3を掴むインサート材把持部26が前述のような構成でなされると、インサート材3を把持する把持プレート17a、17bが薄い板状の構成で掴むことができるので、掴まれるインサート材3自体を回転軸芯Z方向で薄い形状にすることができる。
これにより、被接合部材である第一接合材1と第二接合材2が単純な棒材ではなく異形部材同士を接合する場合においても、薄い形状のインサート材3を挿入できるので、インサート材3の形状の影響で接合後の全体形状を大きく変えることなく接合することができる。
When the insert material gripping portion 26 that grips the insert material 3 of the insert material gripping means 16 is configured as described above, the grip plates 17a and 17b that grip the insert material 3 can be gripped in a thin plate-like configuration. The insert material 3 itself to be gripped can be made thin in the direction of the rotation axis Z.
As a result, even when the first joining material 1 and the second joining material 2 which are the members to be joined are not simple rods but are joined to the deformed members, the insert material 3 having a thin shape can be inserted. It is possible to join without significantly changing the overall shape after joining due to the influence of the shape.
