本発明は、自動車の燃料流路などに用いられる目玉継手
の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing an eye joint used in a fuel flow path of an automobile.
［従来の技術］ 第６図に従来用いられている目玉継手の断面図を示す。[Conventional technology] FIG. 6 shows a sectional view of a conventionally used eye joint.
この目玉継手は、目玉部１００と、パイプ部２００と、
ニップル３００及びスリーブ４００とから構成されてい
る。This eye joint includes an eye portion 100, a pipe portion 200,
It is composed of a nipple 300 and a sleeve 400.
目玉部１００はリング状をなし、縦穴１０１と、縦穴１
０１の内周表面に形成されたリング状の溝部１０２と、
軸方向が縦穴１０１と交差し溝部１０２と外部とを連通
ずることで溝部１０２を介して外部と流路とを連通する
横穴１０３とが形成ざれている。The eyeball part 100 has a ring shape, and has a vertical hole 101 and a vertical hole 1.
A ring-shaped groove 102 formed on the inner circumferential surface of 01;
A horizontal hole 103 is formed whose axial direction intersects with the vertical hole 101 and communicates the groove 102 with the outside, thereby communicating the flow path with the outside via the groove 102.
パイプ部２００は、中心穴が横穴１０３と連通ずるよう
に、一端が目玉部１００とろう付は部２０１により一体
的に結合されている。One end of the pipe portion 200 is integrally connected to the center portion 100 by a brazing portion 201 so that the center hole communicates with the side hole 103.
そして、パイプ部２００の他端には外表面に係止溝３０
１をもつニップル３００がろう付は部２０２により固定
され、係止溝３０１にスリーブ４００が係止されている
。このニップル３００とスリーブ４００とで継手部が構
成されている。A locking groove 30 is provided on the outer surface of the other end of the pipe portion 200.
A nipple 300 having a sleeve 400 is fixed by a brazing portion 202, and a sleeve 400 is locked in a locking groove 301. The nipple 300 and the sleeve 400 constitute a joint portion.

目玉部１００が被取付部と結合される。そして、ホース
内の流体は、ニップル３０Ｃ１よびパイプ部２００を通
過し、横穴１０３から溝部１０２を介してボルト内に形
成された流路を通じて被取付部の流路に流入する。In this joint, the nipple 300 is inserted into the hose, and the sleeve 400 is reduced in diameter to integrally connect the hose, the nipple 300, and the sleeve 400. In addition, a bolt having a flow path inside is inserted into the vertical hole 101 of the centerpiece 100 through a copper washer, etc., and by screwing the bolt into the attached part having the flow path,
The eyeball part 100 is coupled to the attached part. Then, the fluid in the hose passes through the nipple 30C1 and the pipe portion 200, and flows from the side hole 103 through the groove portion 102 into the flow path of the attached part through the flow path formed in the bolt.
このような目玉継手は、従来、全体を切削加工する製造

いる。Conventionally, such eye joints have been formed by a manufacturing method that involves cutting the entire joint. However, this manufacturing method involves a lot of material loss and a large number of man-hours, so in recent years, the centerpiece, pipe, and joint are formed by cutting, etc., and then brazed to these parts.
A method has been adopted in which the entire structure is fixed integrally.
［発明が解決しようとする課題］
しかし、目玉部１００を切削加工するとしても、目玉部
１００が縦穴１０１の内周表面に縦穴１０１より大径の
溝部１０２を有するものであるため、容易に溝部１０２
の切削を行なうことができない。[Problems to be Solved by the Invention] However, even if the eyeball portion 100 is cut, since the eyeball portion 100 has a groove portion 102 with a larger diameter than the vertical hole 101 on the inner peripheral surface of the vertical hole 101, the groove portion is easily cut. 102
It is not possible to perform cutting.
また、目玉部１００とパイプ部２００とをろう付けによ

であり、目玉継手のように高いシール性を必要とする部
品の場合には、シール性が得られているかどうかを検査
することも困難である。Furthermore, even if the eyepiece part 100 and the pipe part 200 are integrally fixed by brazing, it is difficult to confirm whether or not they are brazed together by visual inspection alone. In the case of parts that require sealing properties, it is also difficult to inspect whether sealing properties are obtained.
したがって、従来の目玉継手では、生産性よくかつ低い
コストで目玉継手を製造することができなかったととも
に、ろう付は後の検査工数が多大な負担となっていた。Therefore, with conventional eye joints, it has not been possible to manufacture eye joints with good productivity and at low cost, and brazing requires a large number of inspection steps.
本発明は、上記従来の不具合に鑑みてなされたものであ
