Description

【０００１】
【発明の属する技術分野】
本発明は構造体の製作方法に関する。
【０００２】
【従来の技術】
端部に凸部を有する２つの被接合部材を突き合わせ、凸部側から回転工具を挿入して摩擦攪拌接合を行っている。これは２つの部材の間に隙間がある場合等の減肉を補填するためである。接合後、凸部が不要な場合は凸部を切削して除去し、部材の外面を平滑にする。これは特開平０９−３０９１６４号公報（ＥＰ０７９７０４３Ａ２）に示されている。
また、回転工具の半径方向にカッターを設けたものがある。回転工具は大径部とその先端側に設けた小径部とからなる。小径部は接合部内に入り、大径部と小径部との境は被接合部材に接する。カッターは前記境よりも小径部側に突出している。このカッターは摩擦攪拌接合によって生じたバリを切削するものと考えられる。これは特開平１０−７１４７７号公報（ＵＳＰ５７９４８３５、ＥＰ０８１００５５Ａ１）に示されている。
また、回転工具とカッターを分け、カッターにエンドミルを使用するものがある。これは特開平１０−１７５０８９号公報に示されている。
【０００３】
【発明が解決しようとする課題】
端部に凸部を有する被接合部材を摩擦攪拌接合すると、接合部にバリが発生する。また、凸部が残る。この凸部側を構造物の外面にする場合には、この凸部を切削して除く必要がある。
そこで、回転工具にカッターを付け、接合しながら余分な凸部とバリを切削することが考えられる。
切削によって、切り粉（チップ）が発生する。このチップによって良好な摩擦攪拌接合が困難になる。
【０００４】
この理由について説明する。回転工具の進行方向の前方には光学的に凸部を検知する光学センサを設置している。このセンサは２つ凸部の幅を検出してその中心に回転工具を位置させるものである。また、凸部の高さ位置を検出して、回転工具の挿入量を適正にするものである。
この光学センサの検知範囲にチップが入り、正確な検出ができなくなる。
【０００５】
また、回転工具の前後には、凸部またはその近傍の被接合部材をベッドの押さえるローラを設置している。主として回転工具の後方にはチップが載っているので、後方のローラがチップを押さえる。このため、チップによって被接合部材が傷つくものである。
本発明の目的は、良好な構造体を得る製作方法を提供する。
【０００６】
【課題を解決するための手段】
上述した目的は、接合部に対してカッターを相対的に移動させると共に、前記接合部を検知するセンサによって前記移動の方向において後方のカッターを導き、前記接合部を切削することにより、構造体を製作する方法において、前記カッターと前記センサとの間において、前記移動方向の前方側から後方に向けてまたは前記移動方向に対して横方向から空気を流出させるようになっており、前記センサと前記カッターとの間の仕切りに沿って、前記移動方向に対して斜め側方後方に前記空気を流出させること、によって、達成できる。
【０００７】
【発明の実施の形態】
図１は、本発明の摩擦攪拌接合装置の側面図である。
全体を符号１ａで示す摩擦攪拌接合装置は、接合される２つの部材２０，３０が載置されるテーブル５を有し、接合ヘッド２００はその前後に配設される第１の押えローラユニット１１０と、第２の押えローラユニット１２０とともにテーブル５に対して矢印Ａ方向に相対移動する。
【０００８】
第１の押えローラユニット１１０は、接合ヘッド２００に対して進行方向の前方に配設され、回転ローラ１１２が部材２０，３０の未接合の凸部２２，３２の上面を押える。
第１の押えローラユニット１１０は、エアノズル１１４を有し、接合部のゴミ等の異物を除去する。また、ローラ１１２の転動面から異物を除去する。エアノズル１１４のエアジエットの噴出方向は、移動方向Ａの前方である。または、移動方向に対して側方である。
【０００９】
第２の押えローラユニット１２０は、接合ヘッド２００の進行方向の後方に配設され、回転ローラ１２２が接合ビード５０の上面を押える。第２の押えローラユニット１２０もエアノズル１２４を有し、接合時に発生したチップ等を除去する。これによってローラ１１２の転動面から異物を除去する。エアノズル１１４のエアジエットの噴出方向は、移動方向Ａの前方である。または、移動方向に対して側方である。
【００１０】
図２は、本発明の摩擦攪拌接合装置のヘッドを示す側面図、図３は平面図である。
全体を符号１ａで示す本発明の摩擦攪拌接合装置の接合ヘッド２００は、テーブル５に対して矢印Ａ方向に相対移動すると共に、進行方向に直交する方向Ｂおよび高さ方向Ｃに移動制御される。
【００１１】
ベッド５上には、接合対象である第１の部材２０と第２の部材３０が接合端面４０を接して又は近接して取り付けられている。第１の部材２０は接合用の凸部２２を有し、第２の部材３０も接合用の凸部３２を有する。
ヘッド２００は、回転工具１０とセンサ２１０を備える。回転工具１０は、矢印Ｒ方向に回転しつつ矢印Ａ方向に移動し、部材の接合部に摩擦攪拌接合を施し、接合ビート５０を形成する。
回転工具１０は、バリ取りカッター１２を有し、摩擦攪拌接合時に発生するバリ等を切断する。
【００１２】
ヘッド２００に装備されるセンサ２１０は、箱形のハウジングを有し、カバー２３０により囲われる。カバー２３０は、センサ２１０の一方の側面と回転工具１０に対向する前面を覆う。
ヘッド２００のハウジングの回転工具１０とは反対側の位置には、エアノズル２４０が取り付けられる。
【００１３】
センサ２１０は、光ビーム２１２を部材２０，３０の上面に投射して、部材２０，３０の凸部２２，３２の縁部２４，３４の位置を光学的に検知する。
このセンサ２１０の情報に基づいて、ヘッド２００は矢印Ｂ方向に移動制御され、回転工具１０の中心は、両縁部２４，３４の中心に沿って案内される。または、センサ２１０は接合端面４０の周囲を検出して、前記移動制御を行う。
また、センサ２１０は凸部２２，３２の頂の高さ位置を検知する。これによって加工ヘッド２００は、矢印Ｃ方向に移動制御され、回転工具１０の挿入量を所定にする。
【００１４】
回転工具１０は、バリ取りカッター１２を有し、摩擦攪拌接合を施す際に発生するバリを切断してチップ６０にかえる。また、凸部２２、３２の頂側を切削し、チップ６０にかえる。工具１０の回転の遠心力によって、チップ６０は周囲に飛散する。
【００１５】
カバー２３０の前面板２３２は、ヘッド２００の進行方向Ａと平行した側面板２３１に対して鈍角の折曲角αで折り曲げられて、センサ２１０のハウジングの前面を覆う。前面板２３２は移動方向Ａに対して傾斜している。
エアノズル２４０からエアジエットＪが前面板２３２近傍の側面板２３１に向けて噴出される。エアノズル２４０の噴出口の高さ位置は凸部３２の近くである。
【００１６】
カバー２３０の側面板２３１に突き当たったエアジェットＪは、前面板２３２に沿って、矢印Ｆ方向に偏流されてチップ６０をカバー２３０の開放された側方へ吹き飛ばす。これにより、カバー２３０内に入ったチップ６０を排出できる。移動方向の側方には側面板がなく開放しているので、カバー内に入ったチップ６０を容易に排出できる。また、前面板２３２は傾斜しているので、チップ６０の排出は容易である。
【００１７】
また、前面板２３２の下端と凸部２２、３２等との間Ｇから回転工具１０側に流出する。これにより、チップ６０がカバー２３０内に侵入するのを防止する。また、エアノズル２４０からのエアジエットは凸部２２、３２上のゴミ等の異物を排除する。
エアジェットＪを噴射するエアノズル２４０は、センサ２１０の横方向に設けてもよい。
【００１８】
図４は、回転工具１０の回転中心軸Ｃ1と接合部材の凸部２２，３２との関係を示す。
回転工具１０の先端部には小径部１４が設けられている。回転工具１０の大径部の外周部にはバリ取りカッター１２が形成される。カッター１２の刃は円周上に１つないし２つである。
【００１９】
図４は、回転工具１０の回転中心軸Ｃ1が接合部材の凸部２２，３２に対して９０度の角度で配設されている状態を示す。
実際の接合に際しては、図５に示すように部材の表面に対する垂線Ｃ1に対して、回転工具１０の回転中心軸Ｃ2を角度βだけ傾けて接合する。
この角度βは、接合条件により異なるが、３度程度に選択される。
【００２０】
図６は、回転工具の大径部の先端と、バリ取りカッター１２の位置関係を示す。 （Ａ）はカッター１２の下端が大径部の先端に対して高さ寸法Ｈ1だけ、大径部先端から段差を設けて配設された状態を示す。（Ｂ）は、カッター１２の下端が大径部先端より高さ寸法Ｈ2だけ突出している状態を示す。
カッターの下端を大径部の先端に対して同一の高さに設定することを含めて、バリ取りカッターの配設位置を設定することができる。
【００２１】
図７は、接合ビード部の状態を示す。
（Ａ）に示すように、回転工具１０の大径部の外径寸法Ｄ1は、接合部材２０，３０の凸部２２，３２の幅寸法Ｌ1よりも小さい。そして、バリ取りカッター１２の回転半径Ｄ2は、２２，３２の幅寸法Ｌ1の半分よりも大きく設定される。（Ｂ）に示すように、摩擦攪拌接合装置により接合ビード５０が形成されると、バリ５２が発生する。このままの状態では、接合ビード５０の表面５０ａは、部材２０，３０の表面から高さ寸法Ｔ1の位置となる。
（Ｃ）は、バリを含めてカッター１２により、表面を削り、高さ寸法Ｔ2の位置に平坦面５０ｂが形成されたことを示す。この切削によってチップ６０が発生する。
さらに、（Ｄ）に示すように、この表面を手動工具等で除去して、部材２０，３０と同一の平面５０ｃを得ることができる。前記ステップ（Ｄ）において、バリをとる際にカッター１２によって高さＴ２に切削しているので、手動工具等による切削量を少なくできる。
【００２２】
エアジエットは異物やチップ６０を除く力があればよい。エアジエットは凸部２２、３２と光ビーム２１２との間を通過するようにすることができる。また、移動方向Ａに対して横方向から空気を流出させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to the manufacture how the structure.
[0002]
[Prior art]
Two to-be-joined members having convex portions at the ends are abutted, and a rotary tool is inserted from the convex portion side to perform friction stir welding. This is to compensate for the thinning when there is a gap between the two members. After joining, when the convex portion is unnecessary, the convex portion is cut and removed to smooth the outer surface of the member. This is shown in Japanese Patent Application Laid-Open No. 09-309164 (EP0797043A2).
Moreover, there exists what provided the cutter in the radial direction of the rotary tool. The rotary tool includes a large-diameter portion and a small-diameter portion provided on the tip side. The small diameter portion enters the joint portion, and the boundary between the large diameter portion and the small diameter portion is in contact with the member to be joined. The cutter protrudes to the small diameter part side from the border. This cutter is considered to cut burrs generated by friction stir welding. This is disclosed in Japanese Patent Laid-Open No. 10-71477 (US Pat. No. 5,794,835, EP08110055A1).
Moreover, there exists a thing which uses an end mill for a cutter, dividing a rotary tool and a cutter. This is shown in JP-A-10-175089.
[0003]
[Problems to be solved by the invention]
When a member to be joined having a convex portion at the end is friction stir welded, burrs are generated at the joint. Moreover, a convex part remains. When this convex part side is used as the outer surface of the structure, it is necessary to cut and remove the convex part.
Therefore, it is conceivable to attach a cutter to the rotary tool and cut off the excess protrusions and burrs while joining.
Cutting generates chips (chips). This tip makes it difficult to achieve good friction stir welding.
[0004]
The reason for this will be described. An optical sensor that optically detects the convex portion is installed in front of the rotating tool in the traveling direction. This sensor detects the width of the two convex portions and positions the rotary tool at the center thereof. Moreover, the height position of a convex part is detected and the insertion amount of a rotary tool is made appropriate.
A chip enters the detection range of the optical sensor, and accurate detection cannot be performed.
[0005]
In addition, before and after the rotary tool, a roller for pressing the convex portion or a member to be joined in the vicinity thereof is installed. Since the tip is mainly placed behind the rotary tool, the rear roller presses the tip. For this reason, the member to be joined is damaged by the chip.
An object of the present invention provides a fabrication how to obtain a good structure.
[0006]
[Means for Solving the Problems]
The above-described object is to move the cutter relative to the joint, guide the rear cutter in the direction of movement by a sensor that detects the joint, and cut the joint. In the manufacturing method, between the cutter and the sensor, air is allowed to flow out from the front side in the moving direction toward the rear or from the lateral direction with respect to the moving direction, and the sensor and the sensor This can be achieved by causing the air to flow out obliquely rearward with respect to the moving direction along the partition between the cutter and the cutter.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a side view of the friction stir welding apparatus of the present invention.
The friction stir welding apparatus denoted as a whole by reference numeral 1a has a table 5 on which two members 20 and 30 to be joined are placed, and a joining head 200 is provided with a first presser roller unit 110 disposed before and after that. And the second presser roller unit 120 relative to the table 5 in the direction of arrow A.
[0008]
The first pressing roller unit 110 is disposed forward in the traveling direction with respect to the bonding head 200, and the rotating roller 112 presses the upper surfaces of the unbonded convex portions 22 and 32 of the members 20 and 30.
The first press roller unit 110 has an air nozzle 114 and removes foreign matters such as dust at the joint. Further, the foreign matter is removed from the rolling surface of the roller 112. The jet direction of the air jet of the air nozzle 114 is the front of the moving direction A. Alternatively, it is lateral to the moving direction.
[0009]
The second pressing roller unit 120 is disposed behind the bonding head 200 in the traveling direction, and the rotating roller 122 presses the upper surface of the bonding bead 50. The second presser roller unit 120 also has an air nozzle 124 to remove chips and the like generated at the time of joining. This removes foreign matter from the rolling surface of the roller 112. The jet direction of the air jet of the air nozzle 114 is the front of the moving direction A. Alternatively, it is lateral to the moving direction.
[0010]
FIG. 2 is a side view showing the head of the friction stir welding apparatus of the present invention, and FIG. 3 is a plan view.
The joining head 200 of the friction stir welding apparatus of the present invention, indicated as a whole by the reference numeral 1a, moves relative to the table 5 in the direction of arrow A and is controlled to move in a direction B and a height direction C perpendicular to the traveling direction. .
[0011]
On the bed 5, the first member 20 and the second member 30 to be joined are attached in contact with or close to the joining end surface 40. The first member 20 has a convex portion 22 for joining, and the second member 30 also has a convex portion 32 for joining.
The head 200 includes the rotary tool 10 and a sensor 210. The rotary tool 10 moves in the direction of arrow A while rotating in the direction of arrow R, and performs friction stir welding on the joint portion of the member to form a joining beat 50.
The rotary tool 10 has a deburring cutter 12 and cuts burrs and the like generated during friction stir welding.
[0012]
The sensor 210 mounted on the head 200 has a box-shaped housing and is surrounded by a cover 230. The cover 230 covers one side surface of the sensor 210 and the front surface facing the rotary tool 10.
An air nozzle 240 is attached to a position of the housing of the head 200 opposite to the rotary tool 10.
[0013]
The sensor 210 projects the light beam 212 on the upper surfaces of the members 20 and 30 and optically detects the positions of the edges 24 and 34 of the convex portions 22 and 32 of the members 20 and 30.
Based on the information of the sensor 210, the head 200 is controlled to move in the direction of arrow B, and the center of the rotary tool 10 is guided along the centers of both edges 24 and 34. Alternatively, the sensor 210 detects the periphery of the joint end surface 40 and performs the movement control.
The sensor 210 detects the height position of the tops of the convex portions 22 and 32. As a result, the machining head 200 is controlled to move in the direction of arrow C, and the insertion amount of the rotary tool 10 is set to a predetermined value.
[0014]
The rotary tool 10 has a deburring cutter 12 and cuts burrs that are generated when friction stir welding is performed to replace the chips 60. Further, the top sides of the convex portions 22 and 32 are cut and replaced with the chip 60. The tip 60 is scattered around by the centrifugal force of the rotation of the tool 10.
[0015]
The front plate 232 of the cover 230 is bent at an obtuse bending angle α with respect to the side plate 231 parallel to the traveling direction A of the head 200 to cover the front surface of the housing of the sensor 210. The front plate 232 is inclined with respect to the moving direction A.
The air jet J is ejected from the air nozzle 240 toward the side plate 231 near the front plate 232. The height position of the outlet of the air nozzle 240 is near the convex portion 32.
[0016]
The air jet J that hits the side plate 231 of the cover 230 is drifted along the front plate 232 in the direction of arrow F, and blows the chip 60 to the side where the cover 230 is opened. Thereby, the chip | tip 60 which entered in the cover 230 can be discharged | emitted. Since there is no side plate on the side in the movement direction, the chip 60 contained in the cover can be easily discharged. Moreover, since the front plate 232 is inclined, the chip 60 can be easily discharged.
[0017]
Further, the gas flows out from G between the lower end of the front plate 232 and the convex portions 22 and 32 to the rotary tool 10 side. This prevents the chip 60 from entering the cover 230. Further, the air jet from the air nozzle 240 excludes foreign matters such as dust on the convex portions 22 and 32.
The air nozzle 240 that ejects the air jet J may be provided in the lateral direction of the sensor 210.
[0018]
FIG. 4 shows the relationship between the rotation center axis C1 of the rotary tool 10 and the projections 22 and 32 of the joining member.
A small diameter portion 14 is provided at the tip of the rotary tool 10. A deburring cutter 12 is formed on the outer peripheral portion of the large-diameter portion of the rotary tool 10. There are one or two blades of the cutter 12 on the circumference.
[0019]
FIG. 4 shows a state where the rotation center axis C1 of the rotary tool 10 is disposed at an angle of 90 degrees with respect to the convex portions 22 and 32 of the joining member.
In actual joining, as shown in FIG. 5, the rotation center axis C2 of the rotary tool 10 is joined at an angle β with respect to the perpendicular C1 to the surface of the member.
This angle β varies depending on the joining conditions, but is selected to be about 3 degrees.
[0020]
FIG. 6 shows the positional relationship between the tip of the large diameter portion of the rotary tool and the deburring cutter 12. (A) shows a state in which the lower end of the cutter 12 is provided with a step from the tip of the large diameter portion by a height dimension H1 with respect to the tip of the large diameter portion. (B) shows a state in which the lower end of the cutter 12 protrudes from the tip of the large diameter portion by a height dimension H2.
The arrangement position of the deburring cutter can be set including setting the lower end of the cutter to the same height with respect to the tip of the large diameter portion.
[0021]
FIG. 7 shows the state of the bonded bead portion.
As shown in (A), the outer diameter dimension D1 of the large diameter portion of the rotary tool 10 is smaller than the width dimension L1 of the convex portions 22 and 32 of the joining members 20 and 30. The rotation radius D2 of the deburring cutter 12 is set to be larger than half of the width dimension L1 of 22 and 32. As shown in (B), when the joining bead 50 is formed by the friction stir welding apparatus, a burr 52 is generated. In this state, the surface 50a of the bonding bead 50 is located at a height dimension T1 from the surfaces of the members 20 and 30.
(C) shows that the surface including the burrs was cut by the cutter 12 and the flat surface 50b was formed at the position of the height dimension T2. The chip 60 is generated by this cutting.
Furthermore, as shown in (D), this surface can be removed with a manual tool or the like, and the same plane 50c as the members 20 and 30 can be obtained. In step (D), when the burr is removed, the cutter 12 cuts the height T2, so that the amount of cutting by a manual tool or the like can be reduced.
[0022]
The air jet only needs to have a power to remove foreign matter and the chip 60. The air jet can pass between the convex portions 22 and 32 and the light beam 212. In addition, air can flow out from the lateral direction with respect to the moving direction A.
[0023]
