Description

本発明は、例えば、すべり軸受の分割体の内周面をめっきする際に用いられるめっき装置に関する。   The present invention relates to a plating apparatus used when, for example, the inner peripheral surface of a slide bearing divided body is plated.

すべり軸受は、一対の半円筒状の分割体が合体することにより、形成されている。分割体の内周面は、摺動面である。分割体の内周面には、摺動性を確保するため、めっき層が形成される。一方、分割体の外周面にまでめっき層が形成されると、すべり軸受の外径が大きくなってしまう。また、すべり軸受組付後に、外周面からめっき層が剥離するおそれがある。また、外周面にめっき層が形成されると、その分、内周面へのめっき効率が低下してしまう。このため、分割体の外周面には、めっき層が形成されない方がよい。   The plain bearing is formed by combining a pair of semi-cylindrical divided bodies. The inner peripheral surface of the divided body is a sliding surface. A plating layer is formed on the inner peripheral surface of the divided body to ensure slidability. On the other hand, when the plating layer is formed up to the outer peripheral surface of the divided body, the outer diameter of the slide bearing becomes large. In addition, the plating layer may be peeled off from the outer peripheral surface after the sliding bearing is assembled. Further, when a plating layer is formed on the outer peripheral surface, the plating efficiency on the inner peripheral surface is reduced accordingly. For this reason, it is better not to form a plating layer on the outer peripheral surface of the divided body.

この点、特許文献1には、直方体箱型のめっきラックを備えるめっき装置が開示されている。めっきラックのうち、陽極側の壁部には、上下方向に延びるスリットが形成されている。一方、めっきラックの内部には、すべり軸受の分割体が、複数搭載されている。複数の分割体は、スリットの長手方向(上下方向)に沿って、積層されている。分割体の内周面は、スリットを覆っている。   In this regard, Patent Document 1 discloses a plating apparatus including a rectangular parallelepiped box type plating rack. In the plating rack, a slit extending in the vertical direction is formed on the wall on the anode side. On the other hand, a plurality of slide bearing divided bodies are mounted inside the plating rack. The plurality of divided bodies are stacked along the longitudinal direction (vertical direction) of the slit. The inner peripheral surface of the divided body covers the slit.

めっきラックをめっき液に浸漬すると、スリットを介して、分割体の内周面に、めっき液が付着する。一方、めっきラックは箱型であるため、分割体の外周面には、めっき液が付着しにくい。したがって、内周面と外周面のうち、内周面を主にめっきすることができる。   When the plating rack is immersed in the plating solution, the plating solution adheres to the inner peripheral surface of the divided body through the slit. On the other hand, since the plating rack is box-shaped, it is difficult for the plating solution to adhere to the outer peripheral surface of the divided body. Therefore, an inner peripheral surface can be mainly plated among an inner peripheral surface and an outer peripheral surface.

しかしながら、同文献記載のめっき装置の場合、めっきラックをめっき液に浸漬する際に、分割体の径方向内側(めっき液側、めっきラック外側)と、分割体の径方向外側(空気側、めっきラック内側)と、で圧力差が発生しやすい。言い換えると、めっきラックに浮力が発生しやすい。このため、めっきラックをめっき液に浸漬しにくい。   However, in the case of the plating apparatus described in the same document, when the plating rack is immersed in the plating solution, the radially inner side of the divided body (plating solution side, outer side of the plating rack) and the radially outer side of the divided body (air side, plating) Pressure difference is likely to occur between the inside of the rack). In other words, buoyancy tends to occur in the plating rack. For this reason, it is difficult to immerse the plating rack in the plating solution.

また、めっきラックをめっき液から引き上げる際に、めっきラックがめっき液を持ち出しやすい。すなわち、めっきラックは箱型を呈している。このため、一旦、めっきラックの内部にめっき液が入ってしまうと、めっき液を排出しにくい。   Further, when the plating rack is pulled up from the plating solution, the plating rack easily takes out the plating solution. That is, the plating rack has a box shape. For this reason, once the plating solution enters the inside of the plating rack, it is difficult to discharge the plating solution.

特許文献2には、自動的に開閉可能な、一対の当て板を備えるめっき装置が開示されている。めっき装置は、細板状のめっきラックと、一対の当て板と、開閉自在装置と、を備えている。めっきラックには、すべり軸受の分割体が搭載されている。めっきラックつまり分割体は、めっき液に対して、上側から浸漬される。一対の当て板は、V字状に連結されている。一対の当て板は、めっき液に浸漬されためっきラックを、水平方向両側から挟持可能である。一対の当て板のうち、一方の当て板にはスリットが形成されている。開閉自在装置が一対の当て板を閉じると、一対の当て板が箱状に合体する。箱の内部には、空間が形成される。当該空間には、めっきラックに配置された分割体が収容される。分割体の内周面は、スリットを覆っている。分割体の内周面には、スリットを介して、めっき液が付着する。   Patent Document 2 discloses a plating apparatus including a pair of contact plates that can be automatically opened and closed. The plating apparatus includes a thin plate-shaped plating rack, a pair of contact plates, and an openable / closable device. The plating rack is mounted with a slide bearing divided body. The plating rack, that is, the divided body is immersed in the plating solution from above. The pair of contact plates are connected in a V shape. The pair of contact plates can sandwich the plating rack immersed in the plating solution from both sides in the horizontal direction. Of the pair of contact plates, one of the contact plates has a slit. When the openable / closable device closes the pair of contact plates, the pair of contact plates are combined into a box shape. A space is formed inside the box. The space accommodates the divided body arranged in the plating rack. The inner peripheral surface of the divided body covers the slit. A plating solution adheres to the inner peripheral surface of the divided body through a slit.

同文献記載のめっき装置によると、めっきラックをめっき液に浸漬した後で、めっきラックつまり分割体を、一対の当て板の内部に、収容している。このため、めっきラックをめっき液に浸漬する際に、分割体の径方向内側と、分割体の径方向外側と、で圧力差が発生しにくい。したがって、めっきラックをめっき液に浸漬しやすい。また、めっきラックをめっき液から引き上げる際に、めっきラックがめっき液を持ち出しにくい。   According to the plating apparatus described in the document, after the plating rack is immersed in the plating solution, the plating rack, that is, the divided body is accommodated inside the pair of contact plates. For this reason, when the plating rack is immersed in the plating solution, a pressure difference hardly occurs between the radially inner side of the divided body and the radially outer side of the divided body. Therefore, it is easy to immerse the plating rack in the plating solution. Further, when the plating rack is pulled up from the plating solution, the plating rack is difficult to take out the plating solution.

しかしながら、一般的に、めっき装置の周辺には、めっき液が飛散しやすい。このため、特許文献2に記載のめっき装置の開閉自在装置には、めっき液が付着しやすい。したがって、開閉自在装置の正確な動作が、めっき液の付着により、妨げられるおそれがある。すなわち、特許文献2に記載のめっき装置は、動作信頼性が低い。また、特許文献2に記載のめっき装置は、めっきラックを挟持する一対の当て板や、一対の当て板を開閉駆動する開閉自在装置を備えている。このため、めっき装置の構造が複雑である。   However, in general, the plating solution is likely to be scattered around the plating apparatus. For this reason, the plating solution tends to adhere to the openable / closable apparatus of the plating apparatus described in Patent Document 2. Accordingly, the accurate operation of the openable / closable device may be hindered by the adhesion of the plating solution. That is, the plating apparatus described in Patent Document 2 has low operation reliability. Moreover, the plating apparatus described in Patent Document 2 includes a pair of contact plates that sandwich the plating rack, and an openable / closable device that opens and closes the pair of contact plates. For this reason, the structure of the plating apparatus is complicated.

このように、特許文献1、2に記載のめっき装置の場合、いずれも、めっき作業の際、すべり軸受の分割体を「箱」(特許文献1の場合は「めっきラック」、特許文献2の場合は「一対の当て板」)に閉じこめることにより、分割体の外周面と比較して、分割体の内周面に、優先的にめっき処理を施している。しかしながら、陽極からの電気力線の「箱」内への進入を防ぐ必要があるため、「箱」、延いてはめっき装置の構造が複雑化しやすい。   As described above, in the case of the plating apparatuses described in Patent Documents 1 and 2, in the case of the plating operation, the sliding bearing divided body is divided into a “box” (in the case of Patent Document 1, “plating rack”, and Patent Document 2). In this case, the inner peripheral surface of the divided body is preferentially subjected to plating treatment by being confined to a “pair of contact plates”). However, since it is necessary to prevent the lines of electric force from the anode from entering the “box”, the structure of the “box” and thus the plating apparatus tends to be complicated.

そこで、本発明は、簡単に、処理対象物の外周面と比較して、処理対象物の内周面に、優先的にめっき処理を施すことができるめっき装置を提供することを目的とする。   Accordingly, an object of the present invention is to provide a plating apparatus capable of preferentially performing the plating process on the inner peripheral surface of the processing object as compared with the outer peripheral surface of the processing object.

(1)上記課題を解決するため、本発明のめっき装置は、めっき液が貯留され部分円筒状の処理対象物が配置されるめっき槽と、該めっき槽内に配置され、該処理対象物の内周面に対向する陽極と、該めっき槽内に配置され、該陽極から該処理対象物の外周面に到達する電気力線の少なくとも一部を捕捉するダミー陰極と、を備えることを特徴とする。   (1) In order to solve the above-described problem, a plating apparatus of the present invention includes a plating tank in which a plating solution is stored and a partially cylindrical processing object is disposed, and a plating tank disposed in the plating tank. An anode facing the inner peripheral surface, and a dummy cathode disposed in the plating tank and capturing at least a part of electric lines of force reaching the outer peripheral surface of the object to be processed from the anode. To do.

ここで、「対向」とは、陽極の少なくとも一部と、処理対象物の内周面の少なくとも一部と、がめっき液内の空間を介して、直列に並ぶことをいう。例えば、陽極と、処理対象物の内周面と、の間に、孔付きの別部材(単一でも複数でもよい)が介在している場合を想定する。この場合であっても、孔を介して、陽極の少なくとも一部と、処理対象物の内周面の少なくとも一部と、が直列に並ぶことが可能であれば、「対向」の概念に含まれる。   Here, “opposing” means that at least a part of the anode and at least a part of the inner peripheral surface of the object to be processed are arranged in series via a space in the plating solution. For example, it is assumed that another member with holes (single or plural) is interposed between the anode and the inner peripheral surface of the processing object. Even in this case, if at least a part of the anode and at least a part of the inner peripheral surface of the object to be processed can be arranged in series via the hole, it is included in the concept of “opposing”. It is.

本発明のめっき装置によると、陽極と、処理対象物の内周面と、が対向して配置されている。このため、陽極からの電気力線が、処理対象物の内周面に、到達しやすい。したがって、処理対象物の内周面に、めっき処理が施されやすい。一方、処理対象物の外周面は、陽極に対向していない。また、めっき槽内には、ダミー陰極が配置されている。このため、処理対象物の外周面に向かう電気力線の少なくとも一部は、ダミー陰極により捕捉されてしまう。したがって、処理対象物の外周面に、めっき処理が施されにくい。このように、本発明のめっき装置によると、処理対象物の外周面と比較して、処理対象物の内周面に、優先的にめっき処理を施すことができる。また、本発明のめっき装置によると、めっき槽内にダミー陰極を配置するだけで、簡単に、処理対象物の外周面に、めっき処理が施されるのを抑制することができる。   According to the plating apparatus of the present invention, the anode and the inner peripheral surface of the processing object are arranged to face each other. For this reason, the electric lines of force from the anode easily reach the inner peripheral surface of the object to be processed. Therefore, the plating process is easily performed on the inner peripheral surface of the processing object. On the other hand, the outer peripheral surface of the processing object does not face the anode. A dummy cathode is disposed in the plating tank. For this reason, at least a part of the lines of electric force directed toward the outer peripheral surface of the object to be processed is captured by the dummy cathode. Therefore, it is difficult for the outer peripheral surface of the processing object to be plated. Thus, according to the plating apparatus of this invention, compared with the outer peripheral surface of a process target object, a plating process can be preferentially given to the inner peripheral surface of a process target object. Moreover, according to the plating apparatus of this invention, it can suppress that a plating process is easily performed to the outer peripheral surface of a process target object only by arrange | positioning a dummy cathode in a plating tank.

(1−1)上記(1)の構成において、前記ダミー陰極は、前記めっき槽に対して、交換可能である構成とする方がよい。めっき作業を繰り返すたびに、ダミー陰極には、めっき層が積層されていく。このため、ダミー陰極が劣化し、電気力線を捕捉しにくくなる。この点、本構成によると、劣化したダミー陰極を、めっき層が形成されていない新しいダミー陰極に、交換することができる。このため、安定的に、ダミー陰極により電気力線を捕捉することができる。   (1-1) In the configuration of (1), the dummy cathode is preferably configured to be replaceable with respect to the plating tank. Each time the plating operation is repeated, plating layers are stacked on the dummy cathode. For this reason, a dummy cathode deteriorates and it becomes difficult to capture electric lines of force. In this regard, according to the present configuration, the deteriorated dummy cathode can be replaced with a new dummy cathode having no plating layer. For this reason, the electric lines of force can be stably captured by the dummy cathode.

(2)上記(1)の構成において、前記めっき槽は、前記陽極が配置される陽極室と、前記ダミー陰極が配置される陰極室と、該陽極室と該陰極室とを仕切り自身を貫通する第一貫通孔を有する第一遮蔽部材と、を有し、さらに、該陰極室に配置され、自身を貫通する第二貫通孔を有する第二遮蔽部材を有し、前記処理対象物が搭載されるめっきラックを備え、該第二遮蔽部材は、該第一遮蔽部材と、該処理対象物と、の間に介在し、該処理対象物の内周面は該第二貫通孔を覆っており、該処理対象物の外周面は該陰極室に露出している構成とする方がよい。   (2) In the configuration of (1) above, the plating tank partitions the anode chamber in which the anode is disposed, the cathode chamber in which the dummy cathode is disposed, the anode chamber and the cathode chamber, and penetrates itself. A first shielding member having a first through-hole, and further including a second shielding member disposed in the cathode chamber and having a second through-hole penetrating through the first shielding member. The second shielding member is interposed between the first shielding member and the processing object, and the inner peripheral surface of the processing object covers the second through-hole. The outer peripheral surface of the object to be processed is preferably exposed to the cathode chamber.

めっきラックには、処理対象物が搭載されている。めっきラックは、処理対象物を、めっき槽内のめっき液に浸漬可能である。処理対象物の内周面は、第二貫通孔を覆っている。また、処理対象物の外周面は、陰極室に露出している。このため、処理対象物をめっき液に浸漬する際、処理対象物の内周面は、第二貫通孔を介して、めっき液に浸漬される。並びに、処理対象物の外周面は、直接、めっき液に浸漬される。したがって、本構成によると、めっきラックをめっき液に浸漬する際に、処理対象物の径方向内側と、処理対象物の径方向外側と、で圧力差が発生しにくい。よって、めっきラックをめっき液に浸漬しやすい。また、処理対象物の径方向内側と、処理対象物の径方向外側と、で圧力差が発生しにくいため、処理対象物をめっき液に浸漬する際、処理対象物がめっきラックから脱落しにくい。   An object to be treated is mounted on the plating rack. The plating rack can immerse the processing object in the plating solution in the plating tank. The inner peripheral surface of the processing object covers the second through hole. Further, the outer peripheral surface of the processing object is exposed to the cathode chamber. For this reason, when the processing object is immersed in the plating solution, the inner peripheral surface of the processing object is immersed in the plating solution through the second through hole. In addition, the outer peripheral surface of the processing object is directly immersed in the plating solution. Therefore, according to this configuration, when the plating rack is immersed in the plating solution, a pressure difference hardly occurs between the radial inner side of the processing object and the radial outer side of the processing object. Therefore, it is easy to immerse the plating rack in the plating solution. In addition, since a pressure difference hardly occurs between the inner side in the radial direction of the processing object and the outer side in the radial direction of the processing object, when the processing object is immersed in the plating solution, the processing object is less likely to fall off the plating rack. .

また、めっきラックをめっき液から引き上げる際、処理対象物の内周面は、第二貫通孔を介して、外部と連通している。並びに、処理対象物の外周面は、外部に露出している。このため、めっきラックがめっき液を持ち出しにくい。また、本構成によると、特許文献2の一対の当て板、開閉自在装置のような機構は不要である。このため、動作信頼性が高い。また、構造が簡単である。   Moreover, when pulling up the plating rack from the plating solution, the inner peripheral surface of the processing object communicates with the outside through the second through hole. In addition, the outer peripheral surface of the processing object is exposed to the outside. For this reason, it is difficult for the plating rack to take out the plating solution. Further, according to this configuration, a mechanism such as the pair of contact plates and the openable / closable device disclosed in Patent Document 2 is unnecessary. For this reason, operation reliability is high. Moreover, the structure is simple.

また、特許文献2に記載のめっき装置の場合、めっき作業の際、通常の作業(めっきラックをめっき液に浸漬し、めっきラックをめっき液から引き上げる作業)以外に、開閉自在装置を駆動し、一対の当て板を開閉する作業が、別途必要になる。このため、めっき作業のサイクルタイムが長くなる。これに対して、本構成によると、開閉自在装置を駆動し、一対の当て板を開閉する作業が、不要である。このため、めっき作業のサイクルタイムを短くすることができる。   In addition, in the case of the plating apparatus described in Patent Document 2, in addition to the normal work (work in which the plating rack is immersed in the plating solution and the plating rack is pulled up from the plating solution) during the plating operation, the openable / closable device is driven, An operation for opening and closing the pair of contact plates is separately required. For this reason, the cycle time of a plating operation becomes long. On the other hand, according to this structure, the operation | work which drives an openable / closable device and opens and closes a pair of contact plates is unnecessary. For this reason, the cycle time of the plating operation can be shortened.

(2−1)上記(2)の構成において、前記第二貫通孔は、スリット状を呈しており、複数の前記処理対象物は、該第二貫通孔のスリット長方向に沿って積層された状態で、前記第二遮蔽部材に配置されている構成とする方がよい。本構成によると、複数の処理対象物に対して、一度にめっき処理を施すことができる。   (2-1) In the configuration of (2), the second through hole has a slit shape, and the plurality of processing objects are stacked along the slit length direction of the second through hole. In a state, it is better to have a configuration arranged on the second shielding member. According to this configuration, it is possible to perform plating on a plurality of processing objects at once.

(3)上記(1)または(2)の構成において、前記処理対象物は、すべり軸受の分割体である構成とする方がよい。すべり軸受は、部分円筒状(例えば、半円筒状)の複数の分割体が、合体して形成されている。本構成によると、分割体の外周面と比較して、分割体の内周面(つまり摺動面)に、優先的にめっき処理を施すことができる。   (3) In the configuration of the above (1) or (2), the processing object is preferably a configuration of a slide bearing divided body. The plain bearing is formed by combining a plurality of partial cylindrical (for example, semi-cylindrical) divided bodies. According to this structure, compared with the outer peripheral surface of a division body, a plating process can be preferentially given to the inner peripheral surface (namely, sliding surface) of a division body.

本発明によると、簡単に、処理対象物の外周面と比較して、処理対象物の内周面に、優先的にめっき処理を施すことができるめっき装置を提供することができる。   According to the present invention, it is possible to easily provide a plating apparatus capable of preferentially plating the inner peripheral surface of a processing object as compared with the outer peripheral surface of the processing object.

<めっき装置の動き>
次に、本実施形態のめっき装置の、めっき作業時の動きについて説明する。まず、図6に示すめっきラック3に、左右二列に、複数の分割体n1を搭載する。分割体n1は、第二貫通孔300を後側から覆うように、第二遮蔽部材30の後面に伏設される。
<Movement of plating equipment>
Next, the movement of the plating apparatus of this embodiment during the plating operation will be described. First, a plurality of divided bodies n1 are mounted on the plating rack 3 shown in FIG. The divided body n1 is laid on the rear surface of the second shielding member 30 so as to cover the second through hole 300 from the rear side.

次に、図4に示す陰極側配電部材25に、複数のめっきラック3を吊り下げる。続いて、陰極側配電部材25を、上側から、一対の陰極側ブラケット24に係止する。この際、複数のめっきラック3、つまり複数の分割体n1は、陰極室N内のめっき液Lに、浸漬される。   Next, the plurality of plating racks 3 are suspended from the cathode-side power distribution member 25 shown in FIG. Subsequently, the cathode side power distribution member 25 is locked to the pair of cathode side brackets 24 from above. At this time, the plurality of plating racks 3, that is, the plurality of divided bodies n <b> 1 are immersed in the plating solution L in the cathode chamber N.

続いて、複数の陽極pと、複数の分割体n1と、の間に電圧を印加する。並びに、複数の陽極pと、複数のダミー陰極n2と、の間に電圧を印加する。図2に示すように、陽極pと、第一貫通孔210およびリブ211と、第二貫通孔300と、複数の分割体n1(左右方向に並ぶ10列のうち1列)と、は前後方向(陽極室Pと陰極室Nとが並ぶ方向)に一列に並んでいる。陽極pからの電気力線Aは、第一貫通孔210、リブ211の径方向内側の空間、第二貫通孔300を介して、複数の分割体n1の内周面に到達する。このため、複数の分割体n1の内周面(すべり軸受の摺動面)には、各々、めっき層が形成される。   Subsequently, a voltage is applied between the plurality of anodes p and the plurality of divided bodies n1. In addition, a voltage is applied between the plurality of anodes p and the plurality of dummy cathodes n2. As shown in FIG. 2, the anode p, the first through-hole 210 and the rib 211, the second through-hole 300, and the plurality of divided bodies n1 (one of the 10 rows arranged in the left-right direction) are in the front-rear direction. (Anode chamber P and cathode chamber N are arranged in a line). The electric lines of force A from the anode p reach the inner peripheral surfaces of the plurality of divided bodies n1 through the first through hole 210, the space inside the rib 211 in the radial direction, and the second through hole 300. For this reason, a plating layer is formed on the inner peripheral surface (sliding surface of the slide bearing) of each of the plurality of divided bodies n1.

一方、図3に点線Bで示すように、陽極室P、第一貫通孔210、リブ211の径方向内側の空間、第二貫通孔300、複数の分割体n1の径方向内側の空間と、陰極室Nと、は隔離されている。このため、陽極pからの電気力線Aは、陰極室Nに進入しにくい。   On the other hand, as shown by a dotted line B in FIG. 3, the anode chamber P, the first through hole 210, the radially inner space of the rib 211, the second through hole 300, the radially inner space of the plurality of divided bodies n1, The cathode chamber N is isolated. For this reason, the electric lines of force A from the anode p are unlikely to enter the cathode chamber N.

また、図7に点線で示すように、リブ211の後端と、第二遮蔽部材30の前面と、の間を介して、陰極室N内に、電気力線Aが漏れる場合がある。この場合、電気力線Aが分割体n1の外周面に到達すると、分割体n1の外周面に、めっき層が形成されてしまう。この点、陰極室Nには、ダミー陰極n2が配置されている。このため、陰極室N内に漏出した電気力線Aを、ダミー陰極n2により、捕捉することができる。   Further, as indicated by a dotted line in FIG. 7, the electric force lines A may leak into the cathode chamber N through the space between the rear end of the rib 211 and the front surface of the second shielding member 30. In this case, when the electric lines of force A reach the outer peripheral surface of the divided body n1, a plating layer is formed on the outer peripheral surface of the divided body n1. In this regard, a dummy cathode n2 is disposed in the cathode chamber N. For this reason, the electric lines of force A leaking into the cathode chamber N can be captured by the dummy cathode n2.

このように、陽極pからの電気力線Aは、陰極室Nに進入しにくい。また、電気力線Aが陰極室Nに進入しても、当該電気力線Aを、ダミー陰極n2により、捕捉することができる。このため、分割体n1の外周面にめっき層が形成されるのを、抑制することができる。   Thus, the electric lines of force A from the anode p are unlikely to enter the cathode chamber N. Even if the electric lines of force A enter the cathode chamber N, the electric lines of force A can be captured by the dummy cathode n2. For this reason, it can suppress that a plating layer is formed in the outer peripheral surface of the division n1.

それから、陰極側配電部材25を、一対の陰極側ブラケット24から、上側に持ち上げる。すなわち、複数のめっきラック3、つまり複数の分割体n1を、めっき液Lから引き上げる。その後、複数の分割体n1に対して、仕上げ作業(例えば、水洗作業、バフ研磨作業など)を施す。   Then, the cathode side power distribution member 25 is lifted upward from the pair of cathode side brackets 24. That is, the plurality of plating racks 3, that is, the plurality of divided bodies n <b> 1 are pulled up from the plating solution L. Thereafter, a finishing operation (for example, a water washing operation or a buffing operation) is performed on the plurality of divided bodies n1.

<作用効果>
次に、本実施形態のめっき装置の作用効果について説明する。図7に示すように、陽極pと、分割体n1の内周面と、は第一貫通孔210、リブ211の径方向内側の空間、第二貫通孔300を介して、前後方向に対向している。このため、陽極pからの電気力線Aが、分割体n1の内周面に、到達しやすい。したがって、分割体n1の内周面に、めっき処理が施されやすい。一方、分割体n1の外周面は、陽極pに対向していない。分割体n1の外周面は、陽極pに対して、反対向きに配置されている。また、陰極室N内には、ダミー陰極n2が配置されている。このため、分割体n1の外周面に向かう電気力線の少なくとも一部は、ダミー陰極n2により捕捉されてしまう。したがって、分割体n1の外周面に、めっき処理が施されにくい。このように、本実施形態のめっき装置1によると、分割体n1の外周面と比較して、分割体n1の内周面に、優先的にめっき処理を施すことができる。また、本実施形態のめっき装置1によると、陰極室Nにダミー陰極n2を配置するだけで、簡単に、分割体n1の外周面に、めっき処理が施されるのを抑制することができる。
<Effect>
Next, the effect of the plating apparatus of this embodiment is demonstrated. As shown in FIG. 7, the anode p and the inner peripheral surface of the divided body n1 are opposed to each other in the front-rear direction via the first through hole 210, the radial inner space of the rib 211, and the second through hole 300. ing. For this reason, the electric lines of force A from the anode p can easily reach the inner peripheral surface of the divided body n1. Therefore, the plating process is easily performed on the inner peripheral surface of the divided body n1. On the other hand, the outer peripheral surface of the divided body n1 does not face the anode p. The outer peripheral surface of the divided body n1 is disposed in the opposite direction with respect to the anode p. A dummy cathode n2 is arranged in the cathode chamber N. For this reason, at least a part of the lines of electric force directed toward the outer peripheral surface of the divided body n1 is captured by the dummy cathode n2. Therefore, it is difficult for the outer peripheral surface of the divided body n1 to be plated. Thus, according to the plating apparatus 1 of this embodiment, compared with the outer peripheral surface of the division body n1, a plating process can be preferentially performed to the inner peripheral surface of the division body n1. Further, according to the plating apparatus 1 of the present embodiment, it is possible to easily prevent the outer peripheral surface of the divided body n1 from being plated by simply arranging the dummy cathode n2 in the cathode chamber N.

また、本実施形態のめっき装置1によると、ダミー陰極n2は、めっき槽2に対して、交換可能である。このため、めっき層が形成され劣化したダミー陰極n2を、めっき層が形成されていない新しいダミー陰極n2に、交換することができる。このため、安定的に、ダミー陰極n2により電気力線Aを捕捉することができる。   Moreover, according to the plating apparatus 1 of this embodiment, the dummy cathode n2 is replaceable with respect to the plating tank 2. FIG. For this reason, the dummy cathode n2 in which the plating layer is formed and deteriorated can be replaced with a new dummy cathode n2 in which the plating layer is not formed. For this reason, the electric force line A can be stably captured by the dummy cathode n2.

また、図2、図3に示すように、分割体n1の内周面は、第二貫通孔300を覆っている。また、分割体n1の外周面は、陰極室Nに露出している。このため、分割体n1をめっき液Lに浸漬する際、分割体n1の内周面は、第二貫通孔300を介して、めっき液Lに浸漬される。並びに、分割体n1の外周面は、直接、めっき液Lに浸漬される。したがって、本実施形態のめっき装置1によると、めっきラック3をめっき液Lに浸漬する際に、分割体n1の径方向内側と、処理対象物の径方向外側と、で圧力差が発生しにくい。よって、めっきラック3をめっき液Lに浸漬しやすい。また、分割体n1の径方向内側と、分割体n1の径方向外側と、で圧力差が発生しにくいため、分割体n1をめっき液Lに浸漬する際、分割体n1がめっきラック3から脱落しにくい。   As shown in FIGS. 2 and 3, the inner peripheral surface of the divided body n <b> 1 covers the second through hole 300. Further, the outer peripheral surface of the divided body n1 is exposed to the cathode chamber N. For this reason, when the divided body n1 is immersed in the plating solution L, the inner peripheral surface of the divided body n1 is immersed in the plating solution L through the second through-hole 300. In addition, the outer peripheral surface of the divided body n1 is directly immersed in the plating solution L. Therefore, according to the plating apparatus 1 of this embodiment, when the plating rack 3 is immersed in the plating solution L, a pressure difference is unlikely to occur between the radially inner side of the divided body n1 and the radially outer side of the object to be processed. . Therefore, it is easy to immerse the plating rack 3 in the plating solution L. In addition, since a pressure difference is hardly generated between the radially inner side of the divided body n1 and the radially outer side of the divided body n1, the divided body n1 is dropped from the plating rack 3 when the divided body n1 is immersed in the plating solution L. Hard to do.

また、めっきラック3をめっき液Lから引き上げる際、分割体n1の内周面は、第二貫通孔300を介して、めっきラック3の外部と連通している。並びに、分割体n1の外周面は、めっきラック3の外部に露出している。このため、めっきラック3がめっき液Lを持ち出しにくい。また、本実施形態のめっき装置1によると、特許文献2の一対の当て板、開閉自在装置のような機構は不要である。このため、動作信頼性が高い。また、構造が簡単である。   Further, when the plating rack 3 is pulled up from the plating solution L, the inner peripheral surface of the divided body n1 communicates with the outside of the plating rack 3 through the second through hole 300. In addition, the outer peripheral surface of the divided body n1 is exposed to the outside of the plating rack 3. For this reason, it is difficult for the plating rack 3 to take out the plating solution L. Further, according to the plating apparatus 1 of the present embodiment, a mechanism such as the pair of contact plates and the openable / closable apparatus disclosed in Patent Document 2 is unnecessary. For this reason, operation reliability is high. Moreover, the structure is simple.

また、特許文献2に記載のめっき装置の場合、めっき作業の際、通常の作業(めっきラック3をめっき液Lに浸漬し、めっきラック3をめっき液Lから引き上げる作業)以外に、開閉自在装置を駆動し、一対の当て板を開閉する作業が、別途必要になる。このため、めっき作業のサイクルタイムが長くなる。これに対して、本実施形態のめっき装置1によると、開閉自在装置を駆動し、一対の当て板を開閉する作業が、不要である。このため、めっき作業のサイクルタイムを短くすることができる。   Further, in the case of the plating apparatus described in Patent Document 2, in addition to the normal work (work in which the plating rack 3 is immersed in the plating solution L and the plating rack 3 is pulled up from the plating solution L) during the plating operation, the openable / closable device. The operation of driving and opening and closing the pair of contact plates is separately required. For this reason, the cycle time of a plating operation becomes long. On the other hand, according to the plating apparatus 1 of this embodiment, the operation | work which drives an openable / closable apparatus and opens and closes a pair of contact plates is unnecessary. For this reason, the cycle time of the plating operation can be shortened.

また、図3に示すように、第二貫通孔300は、上下方向に延びるスリット状を呈している。並びに、複数の分割体n1は、上下方向に積層された状態で、第二遮蔽部材30に配置されている。このため、本実施形態のめっき装置1によると、複数の分割体n1に対して、一度にめっき処理を施すことができる。   Moreover, as shown in FIG. 3, the 2nd through-hole 300 is exhibiting the slit shape extended in an up-down direction. In addition, the plurality of divided bodies n1 are arranged on the second shielding member 30 in a state where they are stacked in the vertical direction. For this reason, according to the plating apparatus 1 of this embodiment, it is possible to perform the plating process on the plurality of divided bodies n1 at a time.

また、図2に示すように、陽極pと、第一貫通孔210と、第二貫通孔300と、複数の分割体n1の内周面と、は前後方向に一列に並んでいる。このため、本実施形態のめっき装置1によると、陽極pからの電気力線Aを、最短距離で、分割体n1の内周面に到達させることができる。このため、分割体n1の外周面と比較して、分割体n1の内周面に、優先的にめっき処理を施すことができる。   Further, as shown in FIG. 2, the anode p, the first through hole 210, the second through hole 300, and the inner peripheral surfaces of the plurality of divided bodies n1 are arranged in a line in the front-rear direction. For this reason, according to the plating apparatus 1 of this embodiment, the electric force line A from the anode p can be made to reach the inner peripheral surface of the divided body n1 with the shortest distance. For this reason, compared with the outer peripheral surface of the divided body n1, the plating process can be preferentially performed on the inner peripheral surface of the divided body n1.

また、図3に点線Bで示すように、陽極室P、第一貫通孔210、リブ211の径方向内側の空間、第二貫通孔300、複数の分割体n1の径方向内側の空間と、陰極室Nと、は隔離されている。このため、陽極pからの電気力線Aは、陰極室Nに進入しにくい。したがって、分割体n1の外周面にめっき層が形成されるのを、抑制することができる。また、第一貫通孔210、リブ211の径方向内側の空間、第二貫通孔300により、電気力線Aを、複数の分割体n1の内周面に、誘導することができる。   Further, as indicated by a dotted line B in FIG. 3, the anode chamber P, the first through hole 210, the radial inner space of the rib 211, the second through hole 300, the radial inner space of the plurality of divided bodies n <b> 1, The cathode chamber N is isolated. For this reason, the electric lines of force A from the anode p are unlikely to enter the cathode chamber N. Therefore, it can suppress that a plating layer is formed in the outer peripheral surface of the division n1. Moreover, the electric lines of force A can be guided to the inner peripheral surfaces of the plurality of divided bodies n1 by the first through-hole 210, the space inside the rib 211 in the radial direction, and the second through-hole 300.

<その他>
以上、本発明のめっき装置の実施の形態について説明した。しかしながら、実施の形態は上記形態に特に限定されるものではない。当業者が行いうる種々の変形的形態、改良的形態で実施することも可能である。
<Others>
The embodiment of the plating apparatus of the present invention has been described above. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible.

図2に示すリブ211は、第一遮蔽部材21の後面ではなく、第二遮蔽部材30の前面に、配置してもよい。また、リブ211は、配置しなくてもよい。すなわち、第一遮蔽部材21の後面と、第二遮蔽部材30の前面と、の隙間を介して、陽極pから陰極室Nに、電気力線Aが漏出してもよい。この場合であっても、図2に示すように、分割体n1の内周面と外周面とを比較すると、内周面の方が、外周面よりも、陽極pからの距離が短い。陽極pからの電気力線Aは、第一貫通孔210および第二貫通孔300を介して、分割体n1の内周面に到達する。また、陽極pからの電気力線Aは、第一貫通孔210を介し、第二遮蔽部材30を迂回して、分割体n1の外周面に到達する。このため、内周面の方が、外周面よりも、めっきされやすい。このように、陰極室Nが陽極pに連通することを敢えて許容しながら、陽極pからの距離の差を利用して、分割体n1の外周面と比較して、分割体n1の内周面に、優先的にめっき処理を施してもよい。こうすると、リブ211が不要な分だけ、めっきラック3の構造が簡単になる。   The ribs 211 shown in FIG. 2 may be arranged not on the rear surface of the first shielding member 21 but on the front surface of the second shielding member 30. Further, the rib 211 may not be arranged. That is, the electric lines of force A may leak from the anode p to the cathode chamber N through a gap between the rear surface of the first shielding member 21 and the front surface of the second shielding member 30. Even in this case, as shown in FIG. 2, when the inner peripheral surface and the outer peripheral surface of the divided body n1 are compared, the distance from the anode p is shorter on the inner peripheral surface than on the outer peripheral surface. The electric lines of force A from the anode p reach the inner peripheral surface of the divided body n1 through the first through hole 210 and the second through hole 300. The electric lines of force A from the anode p bypass the second shielding member 30 via the first through hole 210 and reach the outer peripheral surface of the divided body n1. For this reason, the inner peripheral surface is more easily plated than the outer peripheral surface. As described above, the inner peripheral surface of the divided body n1 is compared with the outer peripheral surface of the divided body n1 by utilizing the difference in the distance from the anode p while intentionally allowing the cathode chamber N to communicate with the anode p. In addition, the plating process may be preferentially performed. This simplifies the structure of the plating rack 3 by the amount that the rib 211 is unnecessary.

分割体n1の配置数、積層方向は特に限定しない。例えば、複数の分割体n1を水平方向(前後方向や左右方向)に積層してもよい。また、分割体n1は、半(180°)円筒状でなくてもよい。例えば、1/3(120°)円筒状、1/4(90°)円筒状などであってもよい。また、処理対象物は、すべり軸受の分割体n1でなくてもよい。また、処理対象物の形状は、部分角筒状(例えばV字状)などであってもよい。   The number of the divided bodies n1 and the stacking direction are not particularly limited. For example, a plurality of divided bodies n1 may be stacked in the horizontal direction (front-rear direction and left-right direction).
