【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、適宜ワークの必要な部分にのみ金属被膜
を形成することができるようにしたメッキ方法及びその
装置に関するものである。Description: TECHNICAL FIELD The present invention relates to a plating method and an apparatus thereof capable of forming a metal film only on a necessary portion of a work as appropriate.
第３図に示すように、円筒形シエル10の両端に一対の
フランジ11を内向きに形成し、各フランジ11の内径縁に
環状の折曲片12を設け、上記シエル10の内側において、
一対のフランジ11間に多数のとがり形針状ころ13を組み
込んだ針状ころ軸受は従来から存在する。As shown in FIG. 3, a pair of flanges 11 are formed inward at both ends of the cylindrical shell 10, and an annular bending piece 12 is provided on the inner diameter edge of each flange 11, and inside the shell 10,
Conventionally, needle roller bearings in which a large number of pointed needle rollers 13 are incorporated between a pair of flanges 11 have been known.
上記針状ころ軸受においては、一対の折曲片12間の間
隔が針状ころ13の長さより小さい場合には、シエル10の
内側に針状ころ13を組み込むことができないため、通
常、一対の折曲片12の間隔を針状ころ13の長さより大き

ス加工して一対の折曲片12の間隔を針状ころ13の長さよ
り短くし、針状ころ13の抜け止めを図るようにしてい
る。In the needle roller bearing described above, when the distance between the pair of bent pieces 12 is smaller than the length of the needle roller 13, the needle roller 13 cannot be incorporated inside the shell 10, and thus the pair of bent rollers 12 is usually The distance between the bent pieces 12 is made larger than the length of the needle roller 13, and after the needle roller 13 is assembled, the shell 10 is pressed to make the distance between the pair of bent pieces 12 shorter than the length of the needle roller 13. However, the needle roller 13 is prevented from coming off.
また、針状ころ軸受においては、シエル10の寿命の向
上を図るため、浸炭焼入れを施してシエル10の硬度を高

針状ころ13の組み込み前に行うため、シエル10の全体を
浸炭焼入れすると、針状ころ13の組み込み後のプレス加
工時に、シエル10の端部外周面に亀裂が生じ、不良品の
発生が多くなる。Further, in the needle roller bearing, in order to improve the life of the shell 10, the hardness of the shell 10 is increased by carburizing and quenching. Such carburizing and quenching is usually
Since it is performed before the needle roller 13 is assembled, if the entire shell 10 is carburized and quenched, cracks will occur on the outer peripheral surface of the end of the shell 10 during press working after the needle roller 13 is assembled, resulting in many defective products. Become.
そこで、シエル10の浸炭焼入れに際し、プレス加工さ
れるシエル10の一方の端部外周面をメッキ処理して第４
図の鎖線で示すように、金属被膜14を形成し、その被膜
14により浸炭の防止を図るようにしている。Therefore, at the time of carburizing and quenching the shell 10, the outer peripheral surface of one end of the shell 10 to be pressed is plated and
Form the metal coating 14 as shown by the chain line
14 is used to prevent carburization.
ところで、上記のような金属被膜14は、シエルの一部

シエル10をマスキングし、金属被膜が不必要な部分にマ
スク15を設けてメッキ処理する必要がある。このため、
メッキ処理に非常に手間がかかり、コストを高くつくと
いう不都合がある。By the way, since the metal coating 14 as described above is formed only on a part of the shell, for example, as shown in FIG.
It is necessary to mask the shell 10 and provide a mask 15 on a portion where the metal coating is unnecessary to perform plating treatment. For this reason,
There is an inconvenience that the plating process is very time-consuming and costly.
そこで、この発明は上記の不都合を解消し、ワークの
必要な部分にのみ正確に、精緻な金属被膜を形成するこ
とができるようにしたメッキ方法およびその装置を提供
することをその装置を提供することを目的としている。Therefore, the present invention solves the above-mentioned inconvenience, and provides a plating method and an apparatus thereof capable of accurately forming a fine metal coating only on a necessary portion of a work. Is intended.
上記の目的を達成するために、第１の発明は、メッキ
液を含浸させたスポンジ等の弾力性を有する媒体に、円

上記媒体に接触させた電極とワーク間に通電すると共
に、媒体とワークの少なくとも一方を、ワークの軸心を
中心に回転させてワークの媒体と接触する部分にメッキ
を行なうようにしたのである。In order to achieve the above object, the first invention is to press an end portion of a cylindrical work, which requires a plating treatment, onto an elastic medium such as a sponge impregnated with a plating solution,
The electrode is brought into contact with the medium and the work is energized, and at least one of the medium and the work is rotated about the axis of the work so that the portion of the work that comes into contact with the medium is plated.
また、第２の発明は電極にメッキ液を含浸させたスポ

保持具と媒体の少なくとも一方を他方に対して接触・離
反自在に支持すると共にワークの軸心を中心として回転
自在に支持した構成としたのである。In the second invention, an elastic medium such as a sponge impregnated with a plating solution is brought into contact with the electrode, and a work holder for holding a cylindrical work is opposed to the medium. At least one of them is supported so that it can come into contact with and separate from the other, and is supported so as to be rotatable around the axis of the work.
上記のように構成すれば、ワーク保持具で保持したワ
ークの、メッキ処理を必要とする端部を媒体に押し付け
ることにより、上記媒体が窪み、その窪みの内面がメッ
キ処理を必要とする部分と接触する。According to the above configuration, the work held by the work holder is pressed against the medium by pressing the end portion that requires the plating treatment, the medium is dented, and the inner surface of the dent is a portion that requires the plating treatment. Contact.
そこで、ワーク保持具と媒体の一方を回転し、ワーク
保持具と電極間に通電することにより、媒体と接触する
部分に金属被膜を形成することができる。Therefore, by rotating one of the work holder and the medium and applying an electric current between the work holder and the electrode, a metal coating can be formed on a portion that contacts the medium.
以下、この発明の実施例を第１図および第２図に基づ
いて説明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
第１図に示すように、陽極として使用される電極１に
は、媒体２が取付けられている。この媒体２は、スポン
ジやフェルト等の弾力性を有し、しかも通電性を妨げな
い材料から成り、全体にメッキ液が含浸されている。As shown in FIG. 1, a medium 2 is attached to an electrode 1 used as an anode. The medium 2 is made of a material having elasticity such as sponge and felt, which does not hinder the electrical conductivity, and is entirely impregnated with the plating solution.
上記媒体２に対向配置したワーク保持具３は、媒体２
に対して移動可能に、かつ回転可能に支持されている。The work holder 3 arranged to face the medium 2 is the medium 2
It is movably and rotatably supported with respect to.
ワーク保持具３は、メッキ処理を施すワークＷに対応
してそのワークＷを安定よく保持することができるよう
にしたものを用い、実施例の場合は、媒体２と対向する
面に嵌合孔４を設け、その嵌合孔４で第３図に示すシエ
ル10を保持し得るようになっている。As the work holder 3, a work holder capable of stably holding the work W corresponding to the work W to be plated is used. In the case of the embodiment, a fitting hole is formed on the surface facing the medium 2. 4 is provided so that the shell 10 shown in FIG. 3 can be held in the fitting hole 4.
実施例で示すメッキ装置は上記の構造から成り、ワー
クのメッキ処理に際しては、ワーク保持具３でワークＷ
を保持し、そのワークＷのメッキを必要とする端部を媒
体２に押し込み、ワーク保持具３を回転し、同時にワー
ク保持具３と電極１間に通電する。The plating apparatus shown in the embodiment has the above-mentioned structure, and when the work is plated, the work holder 3 holds the work W.
Is held, the end of the work W requiring plating is pushed into the medium 2, the work holder 3 is rotated, and at the same time, the work holder 3 and the electrode 1 are energized.
いま、第３図に示すシエル10をワーク保持具３で支持
し、ワーク保持具３の下降によってワークＷの下端部を
媒体２に押し付けると、媒体２が窪み、その窪み２′の
内面がワークＷの下部外周面に密着する。Now, when the shell 10 shown in FIG. 3 is supported by the work holder 3 and the lower end of the work W is pressed against the medium 2 by the lowering of the work holder 3, the medium 2 is depressed and the inner surface of the depression 2'is Adheres to the outer peripheral surface of the lower part of W.
そこで、媒体２の内部にメッキを施したい部分だけワ
ークＷを押し込んだのち、電極１とワーク保持具３間に
通電することにより、媒体２と接触する部分に金属被膜
を形成することができる。Then, the work W is pushed into only the portion of the medium 2 where plating is desired, and then the metal film can be formed on the portion in contact with the medium 2 by energizing between the electrode 1 and the work holder 3.
この場合、ワークＷと媒体２が相対的に固定である
と、毛細管現象により、不必要な部分にメッキ液が付着
し、あるいは金属被膜の膜厚が不均一になり易い。In this case, if the work W and the medium 2 are relatively fixed, the plating solution is likely to adhere to unnecessary portions or the thickness of the metal coating film becomes uneven due to the capillary phenomenon.
そこで、メッキ処理時に、ワークＷをその軸心を中心
に回転させることにより、媒体２と接触する部分にの
み、均一厚みの金属被膜14を形成することができる。Therefore, by rotating the work W around the axis thereof during the plating process, the metal coating 14 having a uniform thickness can be formed only on the portion in contact with the medium 2.
第１図に示す実施例においては、ワーク保持具３を回
転させるようにしたが、第２図に示すように、電極１お
よび媒体２をホルダー５で支持し、そのホルダー５をワ
ークＷの軸心を中心に回転させるようにしてもよい。In the embodiment shown in FIG. 1, the work holder 3 is rotated. However, as shown in FIG. 2, the electrode 1 and the medium 2 are supported by the holder 5, and the holder 5 supports the shaft of the work W. You may make it rotate centering on the mind.
また、実施例は、浸炭防止を目的としてワークＷに金

る。Further, in the embodiment, the metal film 14 is provided on the work W for the purpose of preventing carburization, but it can be applied to plating for the purpose of decoration and abrasion resistance. The plating solution is appropriately determined according to the purpose of plating, and when the purpose is to prevent carburization, a copper plating solution such as copper cyanide plating, copper pyrophosphate plating, and copper sulfate plating is used.
