Description
本発明は、センタ―ピンとショルダ―ピンとからなる接合ツ―ルの回転による摩擦熱で被接合物を軟化，撹拌して接合するＦＳＷの接合ツ―ルの清掃方法に関するものである。 The present invention relates to a method for cleaning an FSW joining tool that softens and stirs an object to be joined by frictional heat generated by rotation of a joining tool comprising a center pin and a shoulder pin.
従来，センタ―ピンとショルダ―ピンとからなる接合ツ―ルの回転による摩擦熱で被接合物を軟化，撹拌して接合するＦＳＷであって、センタ―ピンがショルダ―ピン内に挿通されてショルダ―ピンに対してセンタ―ピンの先端が出没するようになされ、撹拌用モ―タにより接合ツ―ルが回転するＦＳＷにおいて、接合ツ―ルである回転子とセンタ―ピンの上端部を固定したホルダとの間にばねを介在させ、このばねの力によりショルダ―ピンの先端からセンタ―ピンが出没するようになされたものがある（例えば、特許文献１参照。）。 Conventionally, an FSW is made by softening and agitating a workpiece by frictional heat generated by rotation of a joining tool composed of a center pin and a shoulder pin. The center pin is inserted into the shoulder pin and the shoulder is inserted. In the FSW in which the tip of the center pin protrudes and protrudes with respect to the pin, and the joining tool rotates by the stirring motor, the rotor as the joining tool and the upper end of the center pin are fixed. There is a structure in which a spring is interposed between the holder and the center pin protrudes and retracts from the tip of the shoulder pin by the force of the spring (see, for example, Patent Document 1).
ところで、上記従来の技術において、ショルダ―ピンの先端からセンタ―ピンが出没する際に、センタ―ピンはショルダ―ピンの中心軸線に穿設した孔内を摺動するものであるが、このセンタ―ピンの摺動部に撹拌接合時に発生する粉塵が侵入して、センタ―ピンの動作が不良となる虞がある。 By the way, in the above prior art, when the center pin protrudes and retracts from the tip of the shoulder pin, the center pin slides in a hole drilled in the central axis of the shoulder pin. -Dust generated during stir welding may invade the sliding part of the pin, causing the center pin to malfunction.
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、ショルダ―ピンとセンタ―ピンとの間に付着した粉塵を機械的に排除し易くして、撹拌接合時におけるセンタ―ピンの動作が正確に行わされ得るようにしたＦＳＷの接合ツ―ルの清掃方法を提供しようとするものである。 The present invention has been made in view of such problems of the prior art, and the object of the present invention is to make it easy to mechanically remove dust adhering between the shoulder pin and the center pin. Thus, an object of the present invention is to provide a method for cleaning a joint tool of FSW so that the operation of the center pin can be accurately performed at the time of stir welding.
上記目的を達成するために、本発明におけるＦＳＷの接合ツ―ルの清掃方法は、ショルダ―ピンに対してセンタ―ピンの出没を制御するセンタ―ピン駆動用モ―タを適用し、該センタ―ピン駆動用モ―タにより、ショルダ―ピンに対してセンタ―ピンの突出ストロ―クおよびショルダ―ピン内へのセンタ―ピンの没入ストロ―クを被接合物の接合動作時に比していずれも大きくし、接合ツ―ルを回転させながら、センタ―ピンが突出時にセンタ―ピンの表面を、センタ―ピンがショルダ―ピンに没入時にショルダ―ピンの孔内面を清掃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 FSW joining tool cleaning method according to the present invention applies a center pin driving motor for controlling the center pin to move in and out of the shoulder pin. -With the pin driving motor, the projecting stroke of the center pin with respect to the shoulder pin and the immersing stroke of the center pin into the shoulder pin are compared with those during the joining operation of the workpiece. The center pin surface was cleaned when the center pin protruded and the inner surface of the hole of the shoulder pin was cleaned when the center pin was immersed in the shoulder pin. It is a characteristic.
本発明に係るＦＳＷの接合ツ―ルの清掃方法では、センタ―ピン駆動用モ―タにより、ショルダ―ピンに対してセンタ―ピンの突出ストロ―クおよびショルダ―ピン内へのセンタ―ピンの没入ストロ―クを被接合物の接合動作時に比していずれも大きくし、接合ツ―ルを回転させながら、センタ―ピンが突出時にセンタ―ピンの表面を、センタ―ピンがショルダ―ピンに没入時にショルダ―ピンの孔内面を清掃するようにしたので、センタ―ピン駆動用モ―タによる通常よりもストロ―クの大きいセンタ―ピンの移動によって粉塵が付着しているセンタ―ピンの外周表面やショルダ―ピンの孔内面は充分に露呈されて刷毛等により容易に清掃され、またその際に接合ツ―ルが回転状態に維持されていることから、センタ―ピンの表面やショルダ―ピンの孔内面が均等に清掃される清掃方法である。 In the FSW joint tool cleaning method according to the present invention, the center pin protruding stroke of the center pin with respect to the shoulder pin and the center pin into the shoulder pin are driven by the center pin driving motor. The immersion stroke is set to be larger than the joining operation of the object to be joined, and while rotating the joining tool, when the center pin protrudes, the center pin surface becomes the center pin becomes the shoulder pin. Since the inner surface of the shoulder pin hole is cleaned when immersed, the outer periphery of the center pin to which dust has adhered due to the movement of the center pin with a stroke larger than usual by the motor for driving the center pin Since the surface and the inner surface of the shoulder pin are sufficiently exposed and easily cleaned with a brush or the like, and the joint tool is maintained in a rotating state at that time, the surface of the center pin and the shoulder pin - a cleaning method pores inside surface of the pin is uniformly cleaned.
ショルダ―ピン２に対してセンタ―ピン１の出没を制御するセンタ―ピン駆動用モ―タ５を適用し、該センタ―ピン駆動用モ―タ５により、ショルダ―ピン２に対してセンタ―ピン１の突出ストロ―クｃおよびショルダ―ピン２内へのセンタ―ピン１の没入ストロ―クｄを被接合物の接合動作時に比していずれも大きくし、接合ツ―ルを回転させながら、センタ―ピン１が突出時にセンタ―ピン１の表面を、センタ―ピン１がショルダ―ピン２に没入時にショルダ―ピン２の孔２６内面を清掃するようにしたＦＳＷの接合ツ―ルの清掃方法である。 A center pin driving motor 5 for controlling the protrusion and withdrawal of the center pin 1 is applied to the shoulder pin 2, and the center pin driving motor 5 is used to center the shoulder pin 2. Both the projecting stroke c of pin 1 and the immersion stroke d of center pin 1 into shoulder pin 2 are made larger than those during the joining operation of the object to be joined, and the joining tool is rotated.

It is a state explanatory view.
ＦＳＷでは、接合すべき被接合物の接合点にセンタ―ピン１を挿入し、該センタ―ピン１の回転による摩擦熱で被接合物の一部を軟化，撹拌して接合するものであり、その接合装置は概略図１に示すような構成を有している。 In FSW, a center pin 1 is inserted at a joint point of workpieces to be joined, and a part of the workpiece is softened and agitated by frictional heat generated by the rotation of the center pin 1 and joined. The joining apparatus has a configuration as shown in FIG.
ロボットの手首にブラケット（図示せず）を介して取付けられた接合装置本体６には加圧用モ―タ４が固着されており、該加圧用モ―タ４の出力軸４１には加圧用ねじ軸４２が固着されている。そして前記接合装置本体６内にはセンタ―ピン駆動用モ―タ５，撹拌用モ―タ３，センタ―ピン１およびショルダ―ピン２の駆動部本体７が内蔵され、また、接合装置本体６の外側前部には固定ア―ム（図示せず）が取り付けられている。なお、上記センタ―ピン１とショルダ―ピン２とで接合ツ―ルが構成されている。 A pressure motor 4 is fixed to a joining apparatus body 6 attached to the wrist of the robot via a bracket (not shown), and a pressure screw is attached to the output shaft 41 of the pressure motor 4. The shaft 42 is fixed. A center pin driving motor 5, a stirring motor 3, a center pin 1 and a shoulder pin 2 drive unit body 7 are built in the joining device body 6. A fixed arm (not shown) is attached to the outer front portion of the. The center pin 1 and the shoulder pin 2 constitute a joining tool.
前記駆動部本体７には前記センタ―ピン駆動用モ―タ５および撹拌用モ―タ３がブラケット７２，７３を介して固着されていると共に該駆動部本体７は加圧用ねじ軸４１のねじと螺合するボ―ルナット７１によりセンタ―ピン軸１１およびショルダ―ピン軸２１を伴って前後進するようになっており、この駆動部本体７は前記接合装置本体６に配置された直動軸受６２によってガイドされるものである。 The center pin driving motor 5 and the agitating motor 3 are fixed to the driving unit body 7 via brackets 72 and 73, and the driving unit body 7 is screwed on the screw shaft 41 for pressurization. A ball nut 71 that is screwed together with the center pin shaft 11 and the shoulder pin shaft 21 moves forward and backward, and this drive unit body 7 is a linear motion bearing disposed in the joining device body 6. 62 is guided.
前記センタ―ピン軸１１は、その先端側に形成されたセンタ―ピン螺着部１３にセンタ―ピン１を螺着するようになされ、該センタ―ピン軸１１の螺着部１３の後方はボ―ルスプライン１４を介してショルダ―ピン軸２１に接続され、後部の中空部１２内には前記加圧用ねじ軸４１の先端側が挿通され、該後部の外周にはねじ１５が螺装されている。 The center pin shaft 11 is configured such that the center pin 1 is screwed into a center pin screwed portion 13 formed on the tip end side thereof, and the rear of the screwed portion 13 of the center pin shaft 11 is a bolt. -It is connected to the shoulder pin shaft 21 through the ruspline 14, the distal end side of the pressure screw shaft 41 is inserted into the rear hollow portion 12, and the screw 15 is screwed on the outer periphery of the rear portion. .
前記センタ―ピン軸１１の後部のねじ１５に螺合するボ―ルネジナット１６にはプ―リ１７が固着されており、ブラケット７２によって駆動部本体７に固着された前記センタ―ピン駆動用モ―タ５からの回転力が伝動ベルト５１，プ―リ１７を介してボ―ルネジナット１６に伝達されるようになっている。そして、このボ―ルネジナット１６の回転によってセンタ―ピン軸１１がショルダ―ピン軸２１に対して前後進する。 A pulley 17 is fixed to a ball screw nut 16 that is screwed to a screw 15 at the rear portion of the center pin shaft 11, and the center pin driving motor fixed to the drive unit body 7 by a bracket 72. The rotational force from the rotor 5 is transmitted to the ball screw nut 16 through the transmission belt 51 and the pulley 17. The center pin shaft 11 moves forward and backward with respect to the shoulder pin shaft 21 by the rotation of the ball screw nut 16.
前記ショルダ―ピン軸２１は、その先端側に形成されたショルダ―ピン固着部２２にショルダ―ピン２をくさび止めするようになされ、該ショルダ―ピン軸２１の中空部の前半部内には前記ボ―ルスプライン１４がキ―止めされ、中空部の後半部内にはセンタ―ピン軸１１の軸受２３が配置され、該後半部の外周にはプ―リ２４が固着されている。 The shoulder pin shaft 21 is configured such that the shoulder pin 2 is wedged to a shoulder pin fixing portion 22 formed on the front end side of the shoulder pin shaft 21. The sprue line 14 is keyed, the bearing 23 of the center pin shaft 11 is disposed in the rear half of the hollow part, and the pulley 24 is fixed to the outer periphery of the rear half.
前記プ―リ２４には、ブラケット７３によって駆動部本体７に固着された前記撹拌用モ―タ３からの回転力が伝動ベルト３１を介して伝達され、この回転によりショルダ―ピン２およびセンタ―ピン１は共に回転するようになっている。 A rotational force from the agitating motor 3 fixed to the drive unit main body 7 by the bracket 73 is transmitted to the pulley 24 via the transmission belt 31, and this rotation causes the shoulder pin 2 and the center to be rotated. The pins 1 are designed to rotate together.
以上のような構成を備えたＦＳＷでは、先ずロボットにより該ＦＳＷの全体が被接合物の所望の接合点に対向するような位置に移動される。 In the FSW having the above-described configuration, first, the entire FSW is moved by the robot to a position facing a desired joining point of the workpiece.
そこで、撹拌用モ―タ３と加圧用モ―タ４とが駆動され、加圧用モ―タ４によるボ―ルナット７１の前進により、駆動部本体７は撹拌用モ―タ３およびセンタ―ピン駆動用モ―タ５を伴って被接合物の接合点に向けて前進すると共に、撹拌用モ―タ３によりショルダ―ピン２およびセンタ―ピン１は共に回転する。この時，センタ―ピン１の先端はショルダ―ピン２のショルダ部２５より突出した状態（図２でａ参照）となっている。 Therefore, the agitating motor 3 and the pressurizing motor 4 are driven, and the ball nut 71 is advanced by the pressurizing motor 4 so that the drive unit body 7 is driven by the agitating motor 3 and the center pin. Advancing toward the joining point of the object to be joined together with the driving motor 5, the shoulder pin 2 and the center pin 1 are both rotated by the agitating motor 3. At this time, the tip of the center pin 1 is in a state of protruding from the shoulder portion 25 of the shoulder pin 2 (see a in FIG. 2).
加圧用モ―タ４によりショルダ―ピン２のショルダ部２５が被接合物の表面に当接した時点では、センタ―ピン１は、被接合物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４による駆動部本体７の前進を停止するが、センタ―ピン１の回転により該センタ―ピン１は、被接合物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の接合を行うものとなる。そして、ショルダ―ピン２のショルダ部２５は溶融状態にある被接合物の表面を加圧する状態にある。 When the shoulder portion 25 of the shoulder pin 2 comes into contact with the surface of the article to be joined by the pressurizing motor 4, the center pin 1 is inserted into the article to be joined and is in a rotating state at the joining point. At this time, the advancement of the drive unit main body 7 by the pressurizing motor 4 is stopped, but the center pin 1 rubs against the object to be joined due to the rotation of the center pin 1 and part of the object to be joined It melt | dissolves and this is stirred, This melt | dissolution thing will join a to-be-joined thing. The shoulder portion 25 of the shoulder pin 2 is in a state of pressurizing the surface of the object to be joined in a molten state.
そして、上記の接合動作が行われると、センタ―ピン駆動用モ―タ５が駆動されて、センタ―ピン１は被接合物の接合点から引き抜かれてショルダ―ピン２のショルダ部２５と同一レベル或はそれより更にショルダ―ピン２内に引き抜かれる（図２でｂ参照）。この間も撹拌用モ―タ３は駆動されているので、回転するショルダ―ピン２のショルダ部２５は被接合物の接合点の表面を平らにするように動作する。 When the above-described joining operation is performed, the center pin driving motor 5 is driven, and the center pin 1 is pulled out from the joining point of the object to be joined and is the same as the shoulder portion 25 of the shoulder pin 2. It is withdrawn into the shoulder pin 2 at level or further (see b in FIG. 2). During this time, since the agitating motor 3 is driven, the shoulder portion 25 of the rotating shoulder pin 2 operates so as to flatten the surface of the joining point of the object to be joined.
なお、ショルダ―ピン２のショルダ部２５に対するセンタ―ピン１の出没は、加圧用モ―タ４や撹拌用モ―タ３の駆動とは関係なく独自にセンタ―ピン駆動用モ―タ５を駆動させることにより任意に調節できるものであり、またショルダ部２５に対するセンタ―ピン１の出没量および加圧力は任意に調節が可能であり、また、該モ―タ５の駆動は接合点の溶解物の状況に応じて必要時に動作させることが可能である。 It should be noted that the center pin 1 is raised and lowered with respect to the shoulder portion 25 of the shoulder pin 2 independently of the driving of the pressurizing motor 4 and the agitating motor 3. It can be arbitrarily adjusted by driving, and the amount of protrusion and the pressing force of the center pin 1 with respect to the shoulder portion 25 and the pressing force can be arbitrarily adjusted, and the motor 5 is driven to dissolve the junction point. It can be operated when necessary according to the situation of the object.
ところで、上記のようなセンタ―ピン１がショルダ―ピン２内に挿通されてショルダ―ピン２に対してセンタ―ピン１の先端が出没するようになされ、撹拌用モ―タ３により接合ツ―ルが回転されるＦＳＷにおいては、ショルダ―ピン２の先端からセンタ―ピン１が出没する際に、センタ―ピン１はショルダ―ピン２の中心軸線に穿設した孔２６内を摺動するものであるが、このセンタ―ピン１の摺動部に撹拌接合時に発生する粉塵が侵入して、センタ―ピン１の動作が不良となる虞がある。 By the way, the center pin 1 as described above is inserted into the shoulder pin 2 so that the tip of the center pin 1 protrudes and retracts from the shoulder pin 2, and is joined by the agitating motor 3. In the FSW that rotates the center pin 1, the center pin 1 slides in the hole 26 formed in the center axis of the shoulder pin 2 when the center pin 1 protrudes and retracts from the tip of the shoulder pin 2. However, there is a possibility that dust generated during the stir welding enters the sliding portion of the center pin 1 and the operation of the center pin 1 becomes defective.
そこで、ＦＳＷによる撹拌接合終了後に、センタ―ピン１とショルダ―ピン２とからなる接合ツ―ルを撹拌用モ―タ３で回転させながら、先ず，センタ―ピン駆動用モ―タ５を駆動してショルダ―ピン２に対してセンタ―ピン１を突出させてその突出ストロ―クをｃ（ｃ〉ａ）とし、この突出したｃの範囲でセンタ―ピン１の表面に付着している粉塵を刷毛等により清掃する。 Therefore, after the stir welding by the FSW is completed, the center pin driving motor 5 is first driven while the joining tool comprising the center pin 1 and the shoulder pin 2 is rotated by the stirring motor 3. Then, the center pin 1 is protruded from the shoulder pin 2 and the protruding stroke is defined as c (c> a). Dust adhering to the surface of the center pin 1 within the range of the protruding c. Clean with a brush.
上記センタ―ピン１の表面の清掃が終了したら、センタ―ピン駆動用モ―タ５を逆転駆動してショルダ―ピン２に対してセンタ―ピン１を没入させてその没入ストロ―クをｄ（ｄ〉ｂ）とし、この没入したｄの範囲でショルダ―ピン２の孔２６内面に付着している粉塵を刷毛等により清掃する。 When the cleaning of the surface of the center pin 1 is completed, the center pin driving motor 5 is driven reversely so that the center pin 1 is immersed in the shoulder pin 2 and the immersion stroke is set to d ( d> b), and the dust adhering to the inner surface of the hole 26 of the shoulder pin 2 is cleaned with a brush or the like within the range of d which has been immersed.
このようにして、被接合物の接合動作時にセンタ―ピン１が突出したときのショルダ―ピン２内でセンタ―ピン１のｃ‐ａの表面及びセンタ―ピン１が没入したときのショルダ―ピン２内でセンタ―ピン１のｄ‐ｂの範囲のショルダ―ピン２の孔２６の内面も清掃されるので、ＦＳＷによる撹拌接合時におけるセンタ―ピン１の動作が正確に行わされ得るようになる。そして、この清掃作業中は接合ツ―ルが回転状態に維持されていることから、センタ―ピン１の表面やショルダ―ピン２の孔２６内面が均等に清掃される。 In this way, the surface of the center pin 1 ca and the shoulder pin when the center pin 1 is immersed in the shoulder pin 2 when the center pin 1 protrudes during the joining operation of the workpieces. 2, the inner surface of the hole 26 of the shoulder pin 2 in the range of db of the center pin 1 is also cleaned, so that the operation of the center pin 1 can be performed accurately during the stir welding by the FSW. . Since the joining tool is maintained in a rotating state during the cleaning operation, the surface of the center pin 1 and the inner surface of the hole 26 of the shoulder pin 2 are evenly cleaned.
なお、これまで主としてスポット接合のＦＳＷについて説明をしたが、本発明に係る清掃方法はスポット接合のＦＳＷに限らず突き合わせ接合のＦＳＷにも適用できるものである。 Although the description has been made mainly on the spot-joint FSW so far, the cleaning method according to the present invention is applicable not only to the spot-joint FSW but also to the butt-joint FSW.
