ところで、上記従来の技術において、接合ツ―ルの先端ショルダ部からツ―ルピンの先端が出没する際に、ツ―ルピンは接合ツ―ルの中心軸線に穿設した孔内を摺動するものであるが、このツ―ルピンの摺動部に撹拌接合時に発生する粉塵が侵入して、ツ―ルピンの作動が不良となる虞がある。   By the way, in the above prior art, when the tip of the tool pin protrudes from the tip shoulder portion of the joint tool, the tool pin slides in the hole drilled in the central axis of the joint tool. However, there is a possibility that dust generated at the time of stir welding enters the sliding portion of the tool pin and the operation of the tool pin becomes poor.
本発明は、従来の技術の有するこのような問題点に鑑みてなされたものであり、その目的とするところは、接合ツ―ルとツ―ルピンとの間に圧縮空気を噴流させて撹拌接合時に発生する粉塵の侵入を防止してツ―ルピンの正確な作動ができるようにした摩擦撹拌スポット接合用ツ―ルピンの目詰り防止装置を提供しようとするものである。   The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to stir and join by compressing compressed air between a joining tool and a tool pin. An object of the present invention is to provide a tool for preventing clogging of a friction stir spot welding tool pin that prevents the intrusion of dust generated at times and enables the tool pin to operate accurately.
上記目的を達成するために、本発明における摩擦撹拌スポット接合用ツ―ルピンの目詰り防止装置は、ツ―ルピンの外周に接合ツ―ルの軸線方向に圧縮空気の噴流通路を形成して接合ツ―ルとツ―ルピン間に侵入する粉塵を排除するようにしたことを特徴とする、ものである。   In order to achieve the above object, the anti-clogging device for a friction stir spot welding tool pin according to the present invention is formed by forming a jet flow passage of compressed air in the axial direction of the welding tool on the outer periphery of the tool pin. It is characterized by eliminating dust entering between the tool and the tool pin.
本発明に係る摩擦撹拌スポット接合用ツ―ルピンの目詰り防止装置では、ツ―ルピンの外周に接合ツ―ルの軸線方向に圧縮空気の噴流通路を形成して接合ツ―ルとツ―ルピン間に侵入する粉塵を排除するようにしたので、接合ツ―ルとツ―ルピンとの間に詰った粉塵も噴流通路を通過する圧縮空気により外部に排出されて、接合ツ―ルからのピンの出没が確実,容易にでき、ツ―ルピンの作動が不良となることがない摩擦撹拌スポット接合用ツ―ルピンの目詰り防止装置となる。   In the anti-clogging device for a friction stir spot welding tool pin according to the present invention, a jet flow passage of compressed air is formed on the outer periphery of the tool pin in the axial direction of the tool tool, and the tool pin and the tool pin are provided. Since dust that intrudes in between is eliminated, dust clogged between the joint tool and the tool pin is also discharged to the outside by compressed air passing through the jet passage, and the pin from the joint tool This is a device for preventing clogging of a friction stir spot welding tool pin that can reliably and easily move in and out and does not cause the tool pin to malfunction.
図1は本発明を実施するのに適した摩擦撹拌スポット接合装置の要部の概略断面図であり、図2は前記摩擦撹拌スポット接合装置の全体の概略構成図である。   FIG. 1 is a schematic cross-sectional view of a main part of a friction stir spot welding apparatus suitable for carrying out the present invention, and FIG. 2 is an overall schematic diagram of the friction stir spot welding apparatus.
摩擦撹拌スポット接合装置では、接合すべき被接合物Wの接合点にツ―ルピン1を挿入し、該ツ―ルピン1の回転による摩擦熱で被接合物Wの一部を軟化,撹拌してスポット接合するものであり、その接合装置は概略図2に示すような構成を有している。   In the friction stir spot welding device, a tool pin 1 is inserted at a joint point of the workpieces W to be joined, and a part of the workpiece W is softened and agitated by frictional heat generated by the rotation of the tool pins 1. Spot joining is performed, and the joining apparatus has a configuration as shown in FIG.
ロボットの手首またはスタンドに設けられた駆動ユニット本体2には加圧用モ―タ3が固着されており、該加圧用モ―タ3の出力軸に接続された加圧部材4によりツ―ルピン抜き用モ―タ5と撹拌用モ―タ6が同時に前後進され、これによって撹拌用モ―タ6に取り付けられた接合ツ―ル7とツ―ルピン1は同時に前後進される。   A pressure motor 3 is fixed to the drive unit main body 2 provided on the wrist or stand of the robot, and the tool pin is removed by the pressure member 4 connected to the output shaft of the pressure motor 3. The motor 5 for agitation and the motor 6 for agitation are simultaneously moved back and forth, whereby the joint tool 7 and the tool pin 1 attached to the motor for agitation 6 are moved back and forth simultaneously.
また、ツ―ルピン1は、前記ツ―ルピン抜き用モ―タ5の出力軸に接続されたピン抜き用ロッド8に接続されており、該ピン抜き用ロッド8の前後進によりツ―ルピン1は接合ツ―ル7に対して摺動しながら前後進する。   Further, the tool pin 1 is connected to a pin removing rod 8 connected to the output shaft of the tool pin removing motor 5, and the tool pin 1 is moved forward and backward by the pin removing rod 8. Moves forward and backward while sliding relative to the joining tool 7.
図1において、ツ―ルピン1の先端面9は接合ツ―ル7の先端のショルダ部10に対して出没自在に配置され、該ツ―ルピン1は接合ツ―ル7の中心軸線方向に穿設した孔11内を前後進するようになされている。また該ツ―ルピン1の後端側はピン保持部材12に螺着されている。   In FIG. 1, the tip surface 9 of the tool pin 1 is disposed so as to be able to protrude and retract with respect to a shoulder portion 10 at the tip of the joining tool 7, and the tool pin 1 is drilled in the direction of the central axis of the joining tool 7. It moves forward and backward in the hole 11 provided. The rear end side of the tool pin 1 is screwed to the pin holding member 12.
前記ピン保持部材12の後端側は例えばベアリング装置(図示せず)を介して前記ピン抜き用ロッド8に接続されている。   The rear end side of the pin holding member 12 is connected to the pin pulling rod 8 via a bearing device (not shown), for example.
13は撹拌用モ―タ6の出力軸14と前記ピン保持部材12との間に配置された接合ツ―ルホルダであり、この接合ツ―ルホルダ13はコレット15を介して接合ツ―ル7の後半の拡径部16を一体的に保持するものである。そして、17は前記コレット15を締め付けるナットであり、このナット17をねじ込むことにより接合ツ―ルホルダ13と接合ツ―ル7とは確実に一体化されるものである。   Reference numeral 13 denotes a joining tool holder disposed between the output shaft 14 of the stirring motor 6 and the pin holding member 12. The joining tool holder 13 is connected to the joining tool 7 via a collet 15. The latter enlarged diameter portion 16 is integrally held. Reference numeral 17 denotes a nut for tightening the collet 15. By screwing the nut 17, the joining tool holder 13 and the joining tool 7 are surely integrated.
また、接合ツ―ルホルダ13と前記ピン保持部材12との間にはすべりキ―18が配置されており、このすべりキ―18によりピン保持部材12は撹拌用モ―タ6の出力軸14からの回転力によって回転すると共に前記ピン抜き用ロッド8によって前後進の動作を行うことが可能となる。   A slide key 18 is disposed between the joint tool holder 13 and the pin holding member 12, and the pin holding member 12 is moved from the output shaft 14 of the agitating motor 6 by the slide key 18. The pinning rod 8 can be moved forward and backward by being rotated by the rotational force.
前記接合ツ―ル7は前半の細径部19と前記後半の拡径部16とで構成され、この接合ツ―ル7の前端面には前述の如くショルダ部10が形成され、細径部19の中心軸線方向には前記孔11が形成され、この孔11内に前記ツ―ルピン1が挿通されており、前記拡径部16は後端が開放した中空室20を有しており、この中空室20内にツ―ルピン1の後部とピン保持部材12の前部が収納されていてツ―ルピン1がピン保持部材12に螺着されている。   The joining tool 7 includes a first-half narrow diameter portion 19 and a second-half enlarged diameter portion 16, and a shoulder portion 10 is formed on the front end surface of the joining tool 7 as described above. The hole 11 is formed in the direction of the central axis 19, the tool pin 1 is inserted into the hole 11, and the enlarged diameter portion 16 has a hollow chamber 20 whose rear end is open, The hollow chamber 20 accommodates the rear part of the tool pin 1 and the front part of the pin holding member 12, and the tool pin 1 is screwed to the pin holding member 12.
以上のような摩擦撹拌スポット接合装置において、撹拌用モ―タ6と加圧用モ―タ3とが駆動され、加圧用モ―タ3によりツ―ルピン抜き用モ―タ5と撹拌用モ―タ3は同時に被接合物Wの接合点に向けて前進すると共に、撹拌用モ―タ6により接合ツ―ル7とツ―ルピン1は共に回転する。この時,ツ―ルピン1の先端は接合ツ―ル7のショルダ部10より突出した状態となっている。   In the friction stir spot welding apparatus as described above, the agitating motor 6 and the pressurizing motor 3 are driven, and the pressurizing motor 3 drives the tool pin removal motor 5 and the agitating motor. At the same time, the tower 3 advances toward the joining point of the workpiece W, and the joining tool 7 and the tool pin 1 are rotated together by the stirring motor 6. At this time, the tip of the tool pin 1 is in a state of protruding from the shoulder portion 10 of the joining tool 7.
加圧用モ―タ3により接合ツ―ル7のショルダ部10が被接合物Wの表面に当接した時点では、ツ―ルピン1は、被接合物W内に挿入されており接合点において回転状態にあり、この時点で加圧用モ―タ3の前進を停止するが、接合ツ―ル7のショルダ部10及びツ―ルピン1の回転により該ショルダ部10及びツ―ルピン1は、被接合物Wと摩擦して被接合物の一部を溶解させこれを撹拌しており、この溶解物が被接合物Wのスポット接合を行うものとなる。   When the shoulder portion 10 of the welding tool 7 comes into contact with the surface of the workpiece W by the pressurizing motor 3, the tool pin 1 is inserted into the workpiece W and rotates at the joining point. At this time, the pressurizing motor 3 stops moving forward. However, the shoulder 10 and the tool pin 1 of the welding tool 7 are rotated to rotate the shoulder 10 and the tool pin 1 together. A part of the object to be bonded is melted by rubbing against the object W and stirred, and the melted object performs spot bonding of the object W to be bonded.
そして、上記の接合動作が行われると、ツ―ルピン抜き用モ―タ5が駆動されて、ツ―ルピン1は被接合物Wの接合点から引き抜かれて接合ツ―ル7のショルダ部10と同一レベル或はそれより更に孔11内に引き抜かれる。この間も撹拌用モ―タ6は駆動されているので、回転する接合ツ―ル7のショルダ部10は被接合物Wの接合点の表面を平らにするように動作する。   When the joining operation is performed, the tool 5 for pulling out the tool pin is driven, and the tool pin 1 is pulled out from the joining point of the workpiece W and the shoulder portion 10 of the joining tool 7 is pulled. Is pulled out into the hole 11 at the same level or more. During this time, since the stirring motor 6 is driven, the shoulder portion 10 of the rotating joining tool 7 operates so as to flatten the surface of the joining point of the article W to be joined.
なお、接合ツ―ル7のショルダ部10に対するツ―ルピン1の出没は、加圧用モ―タ3や撹拌用モ―タ6の駆動とは関係なく独自にツ―ルピン抜き用モ―タ5を駆動させることにより任意にできるものであるから、接合点の溶解物の状況に応じて必要時に作動させるとよい。   It should be noted that the tool pin 1 is raised or lowered with respect to the shoulder portion 10 of the welding tool 7 independently of the driving of the pressurizing motor 3 or the agitating motor 6. Therefore, it may be activated when necessary according to the state of the melt at the junction.
ところで、本発明に係る摩擦撹拌スポット接合装置では、撹拌用モ―タ6の前壁21にリング状の圧縮空気供給台22が取り付けられ、この圧縮空気供給台22に設けた圧縮空気供給口23からの圧縮空気供給導管24は接合ツ―ルホルダ13及び溜り部25を経てピン保持部材12の中心部に至り、次いでピン保持部材12の軸線方向からツ―ルピン1の後部軸線方向に延び、更にツ―ルピン1の径方向に延びて前記接合ツ―ル7の中空室20に至るように形成されている。   By the way, in the friction stir spot welding device according to the present invention, a ring-shaped compressed air supply base 22 is attached to the front wall 21 of the stirring motor 6, and a compressed air supply port 23 provided in the compressed air supply base 22. The compressed air supply conduit 24 from the center reaches the center of the pin holding member 12 through the joint tool holder 13 and the reservoir 25, and then extends from the axial direction of the pin holding member 12 to the rear axial direction of the tool pin 1. It is formed so as to extend in the radial direction of the tool pin 1 and reach the hollow chamber 20 of the joining tool 7.
また、前述の如く、接合ツ―ル7の細径部19の中心軸線方向に孔11が形成され、この孔11内にツ―ルピン1が挿通されているので、接合ツ―ル7とツ―ルピン1の間隙を利用し、ツ―ルピン1の外周にリング状で接合ツ―ル7の軸線方向に圧縮空気の噴流通路26を形成する。   Further, as described above, the hole 11 is formed in the direction of the central axis of the small diameter portion 19 of the joining tool 7, and the tool pin 1 is inserted into the hole 11. -Using the gap of the rupin 1, a compressed air jet passage 26 is formed in the axial direction of the joining tool 7 in the shape of a ring around the outer periphery of the tool pin 1.
したがって、圧縮空気供給口23から圧縮空気を供給すると、供給された圧縮空気は圧縮空気供給導管24により接合ツ―ル7の中空室20に至り、この中空室20からツ―ルピン1の外周でリング状で接合ツ―ル7の軸線方向に延びる圧縮空気の噴流通路26を経て接合ツ―ル7の先端から外部に噴流される。   Therefore, when compressed air is supplied from the compressed air supply port 23, the supplied compressed air reaches the hollow chamber 20 of the joining tool 7 through the compressed air supply conduit 24, and from the hollow chamber 20 to the outer periphery of the tool pin 1. It is jetted from the tip of the joint tool 7 to the outside through a jet passage 26 of compressed air extending in the axial direction of the joint tool 7 in a ring shape.
ところで、摩擦撹拌スポット接合装置において被接合物Wの接合中に溶融した溶融物と共の粉塵が発生するが、この粉塵は接合ツ―ル7とツ―ルピン1との間に侵入しようとする。しかしながら、接合ツ―ル7とツ―ルピン1との間には圧縮空気が流れているので、ツ―ルピン1の外周に侵入しようとする粉塵は防止され、また仮にツ―ルピン1の外周に粉塵が付着していてもその粉塵は圧縮空気の噴流ににより強制的に外部に吹き飛ばされてツ―ルピン1の外周を奇麗にすることから、接合ツ―ル7に対するツ―ルピン1の出没時のツ―ルピン1の動きは確実で容易に可能となる。   By the way, in the friction stir spot welding apparatus, dust is generated together with the melted material during the joining of the workpieces W. This dust tends to enter between the welding tool 7 and the tool pin 1. . However, since compressed air flows between the joining tool 7 and the tool pin 1, dust that tries to enter the outer periphery of the tool pin 1 is prevented. Even if dust adheres, the dust pin is forcibly blown out by the jet of compressed air and the outer periphery of the tool pin 1 is made clean. The tool pin 1 can move reliably and easily.
なお、実施例では、接合ツ―ル7に対するツ―ルピン1の出没にツ―ルピン抜き用モ―タ5を用いたが、この出没には例えば弾性体とエアシリンダによるような普通に知られている機械的な手段を採用してもよく、また、圧縮空気の供給は孔11の根元側に至るまでは如何なる経路を経てもよい。   In the embodiment, the tool 5 for removing the pin of the tool is used to move the tool pin 1 in and out of the joining tool 7. The mechanical means may be employed, and the supply of compressed air may take any route up to the base side of the hole 11.
