Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は突合せ溶接にさきだち互いに溶接すべき板材
を突き合せるための板材突合せ装置に関する。Description: TECHNICAL FIELD The present invention relates to a plate material butt device for abutting plate materials to be welded to each other prior to butt welding.
（従来の技術） 薄板の突合せ溶接を行う場合、突合せ溶接にさきだち
薄板の正確な突合せを行う必要があるが、従来はこの突
合せをつぎのようにして行っている。(Prior Art) When performing butt welding of thin plates, it is necessary to perform accurate butt welding of the thin plates before the butt welding. Conventionally, this butt welding is performed as follows.
すなわち、基準となる基準板材を適宜の手段によって

によって異なったものが用いられる。That is, the reference plate material serving as a reference is fixed by an appropriate means, and the moving plate material to be welded to the reference plate material is moved to match the moving plate material with the reference plate material. Different materials are used depending on the length of the moving plate material.

ーラを回転させることにより、移動板材を基準板材の方
向に移動させるようにしている。That is, when the moving plate is relatively short, the piston plate of the cylinder is directly or indirectly pressed against the rear end of the moving plate (Japanese Utility Model Laid-Open No. 61-97369) so that the moving plate is relatively long. In this case, the movable plate member is moved toward the reference plate member by pressing the roller against the front end portion of the movable plate member (Japanese Utility Model Laid-Open No. 61-97368) and rotating this roller.

安定した突合せができないことになる。(Problems to be Solved by the Invention) In the conventional example as described above, when the moving plate member is moved by the cylinder, the moving plate member may bend depending on the length of the moving plate member, and the axis of the moving plate member may move in the moving direction. If one of the edges of the moving plate material first contacts the reference plate material and then the moving plate material gradually moves in a direction orthogonal to the moving direction, the other edge of the moving plate material Also comes into contact with the reference plate material, but since the moving plate material is merely pressed by the piston rod and is not restricted in any movement in the direction orthogonal to the moving direction, the moving plate material is orthogonal to the moving direction. While moving in the direction, one edge of the moving plate moves slightly along the front end face of the reference plate without holding the stationary state, so that accurate and stable abutment is achieved. So that can not be.
また移動板材をローラにより移動させる場合には、ロ
ーラの押圧力と回転速度との制御が必要になるため、機
構が複雑になる。Further, when the movable plate member is moved by the roller, it is necessary to control the pressing force and the rotation speed of the roller, which complicates the mechanism.
本発明は、上記問題点を解決するためになされたもの

置を得ることを目的とする。The present invention has been made to solve the above problems, and an object of the present invention is to obtain a plate material matching device capable of stable butting with a simple configuration.

どピストンロッドの押圧力が作用しないため、移動板材
がたわむことがない。(Operation) The moving plate material is magnetically attached to a magnet connected to the piston rod of the cylinder and having a predetermined magnetic force (to be attracted by the magnet).
Since the piston rod faces the reference plate member, the moving plate member contacts the reference plate member when the piston rod is extended. By the way, since the reference plate member is fixed, after the moving plate member comes into contact with the reference plate member, its movement is hindered and the magnet slides with respect to the moving plate member. Since the pressing force of the piston rod hardly acts after the contact, the moving plate is not bent.

合せが得られる。If the longitudinal direction of the moving plate is deviated from the moving direction of the moving plate, when the piston rod is extended, one edge of the moving plate first comes into contact with the reference plate, and then the moving plate is centered on the edge. Then, the other edge of the movable plate member abuts the reference plate member, but at this time, the displacement of one edge of the movable plate member in the direction along the front end face of the reference plate member is regulated by the moving magnet, so that it is stable. You get an exact match.

S1だけ離れた位置に位置させる。Next, the operation of the plate material abutting device having the above configuration will be described. First, the reference plate 1 is placed on one of the welding bases 3a, positioned as described above, fixed by the pressing member 6a, and then the moving plate 2 is placed on the moving magnet 8 and magnetically attached. Further, the front end of the moving plate 2 is placed on the other welding base 3b and the rear end of the moving plate 2 is placed on the roller 10. At this time, the front end face of the moving plate member 2 is processed from the butt line l.

板材１に接近する。なお、ピストンロッド9aのストロー
クS2は距離S1よりも充分に大きいものとする。Then, when the cylinder 9 is operated and the piston rod 9a is extended, the moving base 7 moves in the direction of the welding base 3b, and the moving plate 2 magnetically attached to the moving magnet 8 also approaches the reference plate 1. . The stroke S 2 of the piston rod 9a is sufficiently larger than the distance S 1 .
以後の動作は移動板材２の長手方向が移動方向に対し
て一致している場合と、一致していない場合とに分けて
説明する。The subsequent operation will be described separately for the case where the longitudinal direction of the movable plate member 2 is aligned with the moving direction and the case where they are not aligned.
まず、移動板材２の長手方向が移動方向と一致してい

近し基準板材１に当接すると、それ以後は移動用磁石８

はピストンロッド9aの押圧力はほとんど作用しない。First, when the longitudinal direction of the moving plate member 2 coincides with the moving direction, the moving plate member 2 approaches the reference plate member 1 and comes into contact with the reference plate member 1 as described above, and thereafter the moving magnet 8 is moved.
Will slide on the moving plate member 2, and the pressing force of the piston rod 9a hardly acts on the moving plate member 2.
つぎに移動板材２の長手方向が移動方向に対してずれ

２点鎖線で示す位置にある場合について説明する。移動
板材２が前記のごとくして基準板材２に接近していく
と、まず移動板材２の一方のエッジが基準板材２の前端
面に当接する。Next, a case where the longitudinal direction of the moving plate member 2 is deviated from the moving direction, that is, the case where the moving plate member 2 is at the position indicated by the chain double-dashed line as shown in FIG. 1 will be described. When the moving plate member 2 approaches the reference plate member 2 as described above, one edge of the moving plate member 2 first comes into contact with the front end surface of the reference plate member 2.
このとき移動用磁石８の数が、同図に示すように３つ
でかつ移動板材２を横切る方向に並設されている場合に

材１の前端面に沿う方向の変位は移動用磁石８によって
制御されるため、一方のエッジは基準板材１に当接した
後ほとんど変位することがない。At this time, when the number of moving magnets 8 is three and they are arranged side by side in a direction traversing the moving plate member 2, the moving magnets 8a on one edge side are attached to the moving plate member 2, as shown in FIG. Sliding against the other magnets 8b and 8c without sliding
In order to move further, the moving plate member 2 rotates around one edge, and the other edge also contacts the reference plate member 1 as shown by the solid line. At this time, the displacement of one edge in the direction along the front end surface of the reference plate 1 is controlled by the moving magnet 8, so that one edge is hardly displaced after coming into contact with the reference plate 1.
このことは移動用磁石８の数が１つの場合でもいえる
ことで、ただこの場合は磁石８は移動板材２に対してす
べりつつ移動板材２の回動力を与えることになる。This can be said even when the number of the moving magnets 8 is one, but in this case, the magnets 8 give the turning force of the moving plate 2 while sliding on the moving plate 2.
上記のようにして基準板材と移動板材との突合せが完
了したならば移動板材の前端部に押圧部材6bを載置して
移動板材を固定する。When the abutting of the reference plate member and the moving plate member is completed as described above, the pressing member 6b is placed on the front end portion of the moving plate member to fix the moving plate member.
ついでCO2レーザー溶接法あるいはノンフィラーティ
グ溶接法等により突合せ線ｌに沿ってA,B間の溶接を行
う。Then, welding between A and B is performed along the butt line 1 by CO 2 laser welding method or non-filler TIG welding method.
なお、上記では一対の板材1,2の突合せについて述べ
たが、複数の板材の突合せを行うことも可能である。Although the pair of plate members 1 and 2 are butted to each other in the above description, a plurality of plate members can be butted to each other.
（発明の効果） 以上説明したように、本発明は磁石を介して移動板材
にシリンダの駆動力を伝えるので、移動板材が基準板材
に当接した後は磁石は移動板材に対してすべることにな
り、したがって移動板材が突合せ時にたわむことがな
い。(Effects of the Invention) As described above, since the present invention transmits the driving force of the cylinder to the moving plate member via the magnet, the magnet can slide on the moving plate member after the moving plate member contacts the reference plate member. Therefore, the moving plate member does not bend at the time of butting.
また移動板材の長手方向が移動方向に対してずれてい
る場合でも、移動方向と直交する方向の移動板材の変位
は磁石によって規制されるため、正確な突合せが得ら
れ、さらに移動板材の基準板材に対する当接後も磁石は
移動するので隙間のない突合せが達成される。Even if the longitudinal direction of the moving plate is deviated from the moving direction, the displacement of the moving plate in the direction orthogonal to the moving direction is regulated by the magnet, so accurate butting can be obtained, and the reference plate of the moving plate can be obtained. Since the magnet moves even after abutting against, a buttless match is achieved.
さらに磁石を利用するため、移動板材に対する押圧力
の調節が容易であり、かつ移動手段も磁石とシリンダだ
けであるから構成も簡素である。Further, since the magnet is used, it is easy to adjust the pressing force applied to the moving plate material, and the moving means is only the magnet and the cylinder, so that the structure is simple.
