Description
【０００１】[0001]
本考案は溶接用治具に係り、特に磁石組立体における磁力によって溶接が妨げ られるのを防止した溶接用治具に関する。 The present invention relates to a welding jig, and more particularly to a welding jig that prevents welding from being hindered by magnetic force in a magnet assembly.
【０００２】[0002]
本考案の溶接用治具は、例えば、磁気継手装置の被駆動磁石組立体の溶接の際 に用いられるものであるので、まずこの磁気継手装置について図４に基づいて説 明する。図４において、符号１は円筒状の駆動磁石であり、この駆動磁石１の内 径よりも幾分小さな外径を有する円筒状の被駆動磁石２とで構成される一対の永 久磁石が互いに磁気的に結合されている。そして、矢印方向Ａに回転する電気モ ータＭ等に連結されて回転する駆動磁石１のトルクを駆動磁石１および被駆動磁 石２の間に配設されている隔壁３を介して被駆動磁石２に伝達し、この被駆動磁 石２にシャフト４を介して接続された羽根車５を矢印方向Ｂに回転させて揚水を 行うポンプの動力伝達装置がある。これがいわゆる磁気継手装置といわれるもの である。この磁気継手装置においては、取扱い液体中に位置する被駆動磁石２は 流体に直接触れさせないようにするために、図５に示すように、一般的には非着 磁性物質で形成される金属ケーシング６、７および８と前記シャフト４とで被駆 動磁石２を取り囲み被駆動磁石組立体を構成し、この被駆動磁石組立体を密封す るようにしている。 Since the welding jig of the present invention is used, for example, when welding a driven magnet assembly of a magnetic coupling device, the magnetic coupling device will first be described with reference to FIG. In FIG. 4, reference numeral 1 is a cylindrical driving magnet, and a pair of permanent magnets composed of a cylindrical driven magnet 2 having an outer diameter somewhat smaller than the inner diameter of the driving magnet 1 are mutually connected. It is magnetically coupled. Then, the torque of the drive magnet 1 that is connected to the electric motor M that rotates in the direction of the arrow A and rotates is driven through the partition wall 3 that is arranged between the drive magnet 1 and the driven magnet 2. There is a power transmission device for a pump that transmits water to a magnet 2 and rotates an impeller 5 connected to the driven magnet 2 via a shaft 4 in a direction B of an arrow to pump water. This is the so-called magnetic coupling device. In this magnetic coupling device, in order to prevent the driven magnet 2 located in the handled liquid from directly contacting the fluid, as shown in FIG. 5, a metal casing generally formed of a non-magnetic material is used. The driven magnet 2 is surrounded by 6, 7 and 8 and the shaft 4 to form a driven magnet assembly, and the driven magnet assembly is sealed.
【０００３】 従来、密封方法としては種々あるがよく用いられるのは電気溶接である。図５ に示すように、ケーシング６と７の接する部分およびケーシング７とシァフト４ の接する部分である溶接線Ｌ1、並びにケーシング６と８の接する部分およびケ ーシング８とシァフト４の接する部分である溶接線Ｌ2に沿って溶接をするよう にしている。Conventionally, there are various sealing methods, but electric welding is often used. As shown in FIG. 5, a welding line L 1 which is a contact portion between the casings 6 and 7 and a contact portion between the casing 7 and the shaft 4, and a contact portion between the casings 6 and 8 and a contact portion between the casing 8 and the shaft 4. Welding is performed along the welding line L 2 .
【０００４】[0004]
【考案が解決しようとする課題】 しかしながら、このような従来の電気溶接方法にあっては以下に記述するよう な問題点があった。即ち、図６に示すように、被駆動磁石２にはＮ極とＳ極の間 に矢印で表してあるような磁界が存在するため、特にケーシング６と７およびケ ーシング６と８とで形成される溶接線の近傍では溶接のための電気アークが磁力 によって曲げられ、比較的製造コストや溶接機価格の安価なティグ溶接では確実 な密封を行うことが困難であって、非常に歩留まりの悪い加工法となっていた。 この様子を図７に示している。溶接トーチ９と母材であるケーシング７の間には 被駆動磁石２の磁界が矢印で示すように存在するため電極１０から発生する電気 アーク１１は磁界の方向へと曲げられてしまう。[Problems to be Solved by the Invention] However, such a conventional electric welding method has the following problems. That is, as shown in FIG. 6, the driven magnet 2 has a magnetic field between the north pole and the south pole as indicated by the arrow, so that it is formed especially by the casings 6 and 7 and the casings 6 and 8. The electric arc for welding is bent by the magnetic force in the vicinity of the welding line, and it is difficult to perform reliable sealing with TIG welding, which has a relatively low manufacturing cost and welding machine price. It was a processing method. This state is shown in FIG. Since the magnetic field of the driven magnet 2 exists between the welding torch 9 and the casing 7 as the base material as shown by the arrow, the electric arc 11 generated from the electrode 10 is bent in the direction of the magnetic field.
【０００５】 これに対し、実際には電気溶接のうちプラズマ溶接を採用することによって磁 力の影響を最小限におさえる方法がとられているが、これとても最適とは言い難 く、また一般のアーク溶接機に比べて価格が高い点も欠点の一つである。On the other hand, in practice, a method of minimizing the influence of magnetic force is adopted by adopting plasma welding among electric welding. Another drawback is that the price is higher than that of an arc welder.
【０００６】 本考案は上記問題点を解決するためになされたもので、その目的は磁石の磁束 を溶接線および溶接のための電気アークが存在する空間以外へ導き、同磁石の磁 力によって電気アークの直進性が失われないよう、即ち、電気溶接を容易ならし めるように設置される溶接用治具を提供することにある。The present invention has been made to solve the above problems, and its purpose is to guide the magnetic flux of a magnet to a space other than the space where a welding line and an electric arc for welding exist, and to generate electric power by the magnetic force of the magnet. It is an object of the present invention to provide a welding jig that is installed so that the straightness of the arc is not lost, that is, electric welding is facilitated.
【０００７】[0007]
上記目的を達成するため本考案による溶接用治具にあっては以下の構成とした 。即ち、磁石の磁束を溶接線および溶接のための電気アークが存在する空間以外 へ導き、同磁石の磁力によって電気アークの直進性が失われないように、分割可 能な形状でかつ着磁性材料で形成され配設されてなり、また、円筒状磁石と、こ の円筒状磁石を囲繞する非着磁性物質からなる複数のケーシング部材とを有する 磁石組立体があり、これら非着磁性物質の間を溶接によって密封する際に用いら れるものであって、前記円筒状磁石の磁力によって溶接のための電気アークの直 進性が失われないように、分割可能な環状または円筒状の形状でかつ着磁性材料 で形成され、溶接線の近傍に配設されてなる溶接用治具。 In order to achieve the above object, the welding jig according to the present invention has the following configuration. That is, the magnetic flux of the magnet is guided to a place other than the space where the welding line and the electric arc for welding exist, and the magnetic force of the magnet prevents the electric arc from losing its straightness. There is a magnet assembly having a cylindrical magnet and a plurality of casing members made of a non-magnetic material surrounding the cylindrical magnet. Is used for sealing by welding, and has a separable annular or cylindrical shape so that the magnetic force of the cylindrical magnet does not lose the straightness of the electric arc for welding. A welding jig made of a magnetizable material and placed near the welding line.
【０００８】[0008]
上記構成によれば、電気溶接の際に悪影響を及ぼす磁石の磁束を、着磁性材料 で形成された溶接用治具に吸収して溶接線の近傍の磁界を非常に稀薄にできるの で、磁界によって電気アークが曲げられることがなく信頼性の高い溶接加工を施 すことが可能になる。 According to the above configuration, the magnetic flux of the magnet, which has an adverse effect on electric welding, is absorbed by the welding jig formed of the magnetized material, and the magnetic field in the vicinity of the welding line can be extremely diluted. This makes it possible to perform highly reliable welding without bending the electric arc.

以下、本考案の実施例を図１乃至図３に基づいて説明する。 図１は本考案の溶接用治具２０の構造の一例を示すものであって、この治具２ ０は二つもしくはそれ以上の複数に分割可能な環状または円筒状の形状をなすも のである。この実施例では二つに分割でき、それぞれがネジ止め部２１にネジ等 を使用して締め付けることによって円筒状の形状となるようになっている。そし て、その材質は基本的には着磁性材料であれば何でもよいが、図１の破線で示す 矢印で表したような方向に透磁率の高い材料を用いれば尚よい。 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an example of the structure of a welding jig 20 of the present invention. The jig 20 has an annular or cylindrical shape that can be divided into two or more pieces. .. In this embodiment, it can be divided into two parts, each of which has a cylindrical shape by being tightened by using a screw or the like. The material may be basically any magnetically permeable material, but it is more preferable to use a material having a high magnetic permeability in the direction shown by the arrow shown by the broken line in FIG.
【００１０】 図２は本考案の溶接用治具２０を使用する場合の態様を示すものであって、（ ａ）はその正面図であり、（ｂ）はその平面図である。図２（ａ）は前記磁気継 手装置の被駆動磁石組立体を示し、基本的には、この被駆動磁石組立体の仮組み されたものを図５に示す溶接線Ｌ1およびＬ2に沿って溶接するのであるが、この 実施例ではケーシング６と７とで形成される溶接線に沿って溶接する場合を示し ている。溶接用治具２０は円筒状ケーシング６の外周面であってその上端部にネ ジ２２等により締め付けることによって設けられており、これによって図２（ｂ ）に示すように被駆動磁石２の磁束２３は空気中よりも透磁率の高い溶接用治具 ２０の内部を通る。その結果、溶接線の近傍の磁界は非常に稀薄となり、磁界に よって電気アークが曲げられることがなく、信頼性の高い溶接加工を施すことが 可能となる。2A and 2B show an embodiment in which the welding jig 20 of the present invention is used. FIG. 2A is a front view thereof, and FIG. 2B is a plan view thereof. FIG. 2 (a) shows a driven magnet assembly of the magnetic coupling device. Basically, a temporary assembly of the driven magnet assembly is applied to welding lines L 1 and L 2 shown in FIG. The welding is performed along the welding line. In this embodiment, welding is performed along the welding line formed by the casings 6 and 7. The welding jig 20 is provided on the outer peripheral surface of the cylindrical casing 6 by fastening it to the upper end of the cylindrical casing 6 with a screw 22 or the like, which causes the magnetic flux of the driven magnet 2 to be reduced as shown in FIG. 23 passes through the inside of the welding jig 20 having a magnetic permeability higher than that in the air. As a result, the magnetic field in the vicinity of the welding line is extremely diluted, the electric arc is not bent by the magnetic field, and reliable welding can be performed.
【００１１】 図３は本考案の溶接用治具２０を使用する場合の別の態様を示すものである。 この実施例では溶接用治具２０を締め付ける方法をネジ等によらず、施盤に使用 されているチャック２４に直接治具２０を固定する方法によっている。その他の 点は図２の場合と同じである。この方法によれば、チャック２４は図示しないハ ンドルの操作によって水平方向に矢印Ｃの方向へ動くため溶接用治具２０の被駆 動磁石組立体への着脱が容易となり、量産する場合に好適である。被駆動磁石組 立体並びに溶接用治具２０を含めたチャック２４全体は図示しない低速回転モー タによって駆動され矢印Ｄの方向または逆方向へ回転するようになっている。FIG. 3 shows another mode in which the welding jig 20 of the present invention is used. In this embodiment, the method of tightening the welding jig 20 is not a screw or the like but a method of directly fixing the jig 20 to the chuck 24 used for the lathe. The other points are the same as in the case of FIG. According to this method, the chuck 24 moves horizontally in the direction of the arrow C by the operation of the handle (not shown), so that the welding jig 20 can be easily attached to and detached from the driven magnet assembly, which is suitable for mass production. Is. The entire chuck 24 including the driven magnet assembly and the welding jig 20 is driven by a low-speed rotating motor (not shown) to rotate in the direction of arrow D or in the opposite direction.
【００１２】 以上説明したように、本考案によれば磁石の磁界の影響をうけることなく良好 に電気溶接が可能となることが重要であって、その実施の態様は図示したものに 限定されない。形状その他は磁石組立体等の形に応じて適宜変更可能である。As described above, according to the present invention, it is important that good electric welding can be performed without being affected by the magnetic field of the magnet, and the embodiment thereof is not limited to the illustrated one. The shape and the like can be appropriately changed according to the shape of the magnet assembly and the like.
【００１３】[0013]
以上に説明したように、本考案によれば以下のような効果がある。 As described above, the present invention has the following effects.
【００１４】 即ち、磁石の磁界による悪影響がないので溶接加工の不良が低減し、歩留まりが 向上する。また、磁力の影響を受けにくい特殊で高価な溶接機を用いた溶接方法 によらずとも加工が可能であるため、設備費を安くでき製品のコストダウンにも なった。That is, since there is no adverse effect of the magnetic field of the magnet, defects in the welding process are reduced and the yield is improved. In addition, since it is possible to perform processing without using a welding method that uses a special and expensive welding machine that is not easily affected by magnetic force, equipment costs can be reduced and product costs can be reduced.
