Description

本発明は、金属部材と樹脂部材の接合方法及びそれを用いた二槽式オイルパンの製造方法に関する。   The present invention relates to a method for joining a metal member and a resin member and a method for producing a two-tank oil pan using the same.

従来、金属部材と樹脂部材の接合方法として、レーザ溶着法が知られている。このレーザ溶着法は、金属部材と樹脂部材とを重ね合わせ、樹脂部材側からレーザ光を照射することで、樹脂部材と金属部材の境界部分を加熱し、その境界部分で樹脂部材を溶融して両部材を一体的に接合するものである（例えば、特許文献１参照）。   Conventionally, a laser welding method is known as a method for joining a metal member and a resin member. In this laser welding method, a metal member and a resin member are overlapped, and a laser beam is irradiated from the resin member side, thereby heating a boundary portion between the resin member and the metal member, and melting the resin member at the boundary portion. Both members are integrally joined (for example, refer to Patent Document 1).

以下、本発明の一実施形態を図１〜図５に基づいて説明する。図１に示すように、本実施形態に係る二槽式オイルパン１０は、外槽パン１１の内側に内槽パン２０を備えてなる。外槽パン１１は、金属で構成され、内槽パン２０は、着色樹脂で構成されている。着色樹脂は、透明樹脂に着色剤が添加されることで得られる。透明樹脂の具体例としては、ポリオレフィン系樹脂、ポリエステル系樹脂、ポリアミド系樹脂、ポリカーボネート系樹脂等が挙げられる。   Hereinafter, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the two-tank oil pan 10 according to this embodiment includes an inner tank pan 20 inside an outer tank pan 11. The outer tank pan 11 is made of metal, and the inner tank pan 20 is made of a colored resin. The colored resin is obtained by adding a colorant to the transparent resin. Specific examples of the transparent resin include polyolefin resins, polyester resins, polyamide resins, and polycarbonate resins.

外槽パン１１及び内槽パン２０の上部には、外側に張り出したフランジ部１２，２１が設けられ、フランジ部１２，２１は、互いに重ね合わされて、周方向の複数箇所で固定されている。   Flange portions 12 and 21 projecting outward are provided on the upper portions of the outer tank pan 11 and the inner tank pan 20, and the flange portions 12 and 21 are overlapped with each other and fixed at a plurality of locations in the circumferential direction.

また、外槽パン１１のフランジ部１２は、内槽パン２０のフランジ部２１よりも外径が大きくなっていて、このフランジ部１２がエンジンブロック９０のフランジ部９０Ｆに固定されることで、二槽式オイルパン１０がエンジンブロック９０に組み付けられる。   Further, the flange portion 12 of the outer tank pan 11 has an outer diameter larger than that of the flange portion 21 of the inner tank pan 20, and the flange portion 12 is fixed to the flange portion 90F of the engine block 90. The tank type oil pan 10 is assembled to the engine block 90.

ところで、本実施形態では、上述したように、内槽パン２０が着色樹脂で構成されていて、レーザ光に対して透過性を有さない。このため、従来のレーザ溶着のように、両フランジ部１２，２１を重ねた状態でフランジ部２１側からレーザ光を照射しても、レーザ光が両フランジ部１２，２１の境界面まで到達せず、両フランジ部１２，２１を溶着することができない。   By the way, in this embodiment, as above-mentioned, the inner tank pan 20 is comprised with colored resin, and does not have a transmittance | permeability with respect to a laser beam. For this reason, even if the laser beam is irradiated from the flange portion 21 side with both the flange portions 12 and 21 overlapped as in the conventional laser welding, the laser beam can reach the boundary surface between the flange portions 12 and 21. Therefore, the two flange portions 12 and 21 cannot be welded.

そこで、本実施形態では、以下に示す接合方法によって、両フランジ部１２，２１を接合する。なお、外槽パン１１のフランジ部１２が本発明の「金属部材」に相当し、内槽パン２０のフランジ部２１が本発明の「樹脂部材」に相当する。以下、外槽パン１１のフランジ部１２を「金属フランジ部１２」と、内槽パン２０のフランジ部２１を「樹脂フランジ部２１」と称して、両フランジ部１２，２１を適宜区別することにする。   Therefore, in the present embodiment, both flange portions 12 and 21 are joined by the joining method described below. The flange portion 12 of the outer tank pan 11 corresponds to the “metal member” of the present invention, and the flange portion 21 of the inner tank pan 20 corresponds to the “resin member” of the present invention. Hereinafter, the flange portion 12 of the outer tub pan 11 is referred to as “metal flange portion 12” and the flange portion 21 of the inner tub pan 20 is referred to as “resin flange portion 21”, and the two flange portions 12, 21 are appropriately distinguished. To do.

金属フランジ部１２と樹脂フランジ部２１とを接合するには、まず、図２に示すように、樹脂フランジ部２１に貫通孔２２を形成しておく。また、金属フランジ部１２の上面１２Ｍ（即ち、樹脂フランジ部２１との対向面）のうち貫通孔２２が重なる部分に、レーザ加工により凹凸部１５を形成しておく。なお、貫通孔２２は、樹脂フランジ部２１に既に形成されているものであってもよいし、新たに形成されるものであってもよい。   In order to join the metal flange portion 12 and the resin flange portion 21, first, as shown in FIG. 2, a through hole 22 is formed in the resin flange portion 21. Moreover, the uneven | corrugated | grooved part 15 is formed by the laser processing in the part which the through-hole 22 overlaps among the upper surfaces 12M (namely, surface facing the resin flange part 21) of the metal flange part 12. FIG. In addition, the through-hole 22 may be already formed in the resin flange part 21, and may be newly formed.

次いで、金属フランジ部１２の上に樹脂フランジ部２１を重ね、貫通孔２２に中間樹脂部材３０を挿入する。中間樹脂部材３０は、樹脂フランジ部２１と同じ着色樹脂で構成され、厚さが樹脂フランジ部１２よりも十分に薄くなっている。   Next, the resin flange portion 21 is overlaid on the metal flange portion 12, and the intermediate resin member 30 is inserted into the through hole 22. The intermediate resin member 30 is made of the same colored resin as the resin flange portion 21 and has a thickness sufficiently smaller than that of the resin flange portion 12.

次いで、レーザ溶着により、中間樹脂部材３０を、金属フランジ部１２と樹脂フランジ部２１とに接合する。具体的には、図３に示すように、レーザ光照射装置８０を用いて、樹脂フランジ部２１側から中間樹脂部材３０にレーザ光を照射する。ここで、上述の如く、中間樹脂部材３０は、樹脂フランジ部２１（内槽パン２０）と同じ着色樹脂で構成されているが、厚さが樹脂フランジ部２１よりも十分に薄くなっているので、厚さ方向でレーザ光を透過させる。即ち、中間樹脂部材３０は、レーザ光に対して透過性を有している。   Next, the intermediate resin member 30 is joined to the metal flange portion 12 and the resin flange portion 21 by laser welding. Specifically, as shown in FIG. 3, laser light is irradiated onto the intermediate resin member 30 from the resin flange portion 21 side using a laser light irradiation device 80. Here, as described above, the intermediate resin member 30 is made of the same colored resin as the resin flange portion 21 (inner tank pan 20), but the thickness is sufficiently thinner than the resin flange portion 21. The laser beam is transmitted in the thickness direction. That is, the intermediate resin member 30 is transmissive to laser light.

なお、レーザ光照射装置８０は、上述した凹凸部１５の加工にも用いられる。また、レーザ光照射装置８０が、複数種類の波長（例えば、２倍波、３倍波）を照射可能である場合には、レーザ加工で用いるレーザ光の波長と、レーザ溶着で用いるレーザ光の波長とを変更してもよい。   In addition, the laser beam irradiation apparatus 80 is used also for the process of the uneven | corrugated | grooved part 15 mentioned above. Further, when the laser beam irradiation device 80 can irradiate a plurality of types of wavelengths (for example, second harmonic and third harmonic), the wavelength of the laser beam used for laser processing and the laser beam used for laser welding The wavelength may be changed.

中間樹脂部材３０にレーザ光が照射されると、レーザ光は、中間樹脂部材３０を透過し、金属フランジ部２１に吸収される。その結果、中間樹脂部材３０と金属フランジ部２１との境界部分が加熱され、中間樹脂部材３０が金属フランジ部２１に溶着する。   When the intermediate resin member 30 is irradiated with laser light, the laser light passes through the intermediate resin member 30 and is absorbed by the metal flange portion 21. As a result, the boundary portion between the intermediate resin member 30 and the metal flange portion 21 is heated, and the intermediate resin member 30 is welded to the metal flange portion 21.

図４に拡大して示すように、貫通孔２２の奥部では、溶融した中間樹脂部材３０が、凹凸部１５の谷部に流れ込む。これにより、中間樹脂部材３０が金属フランジ部１２に対して横方向にずれることが抑えられ、接合強度の向上が図られる。   As shown in an enlarged view in FIG. 4, the melted intermediate resin member 30 flows into the valleys of the concavo-convex portion 15 in the inner portion of the through hole 22. Thereby, it is suppressed that the intermediate resin member 30 shift | displaces to the horizontal direction with respect to the metal flange part 12, and the improvement of joining strength is achieved.

また、貫通孔２２の奥部の外側部分では、少量の中間樹脂部材３０が、樹脂フランジ部１２と金属フランジ部２１との間の隙間に流れ込み、金属フランジ部２１と樹脂フランジ部１２とに接合される。   Further, a small amount of the intermediate resin member 30 flows into the gap between the resin flange portion 12 and the metal flange portion 21 in the outer portion at the back of the through hole 22 and is joined to the metal flange portion 21 and the resin flange portion 12. Is done.

なお、このとき、レーザ光の照射角度を変更して、中間樹脂部材３と樹脂フランジ部１２との境界部分を照射すれば、中間樹脂部材３０の外周部と樹脂フランジ部１２のうち貫通孔２２の縁部を溶融させて、中間樹脂部材３０の外周部と貫通孔２２の縁部とを接合することも可能である。   At this time, if the irradiation angle of the laser beam is changed to irradiate the boundary portion between the intermediate resin member 3 and the resin flange portion 12, the through hole 22 in the outer peripheral portion of the intermediate resin member 30 and the resin flange portion 12. It is also possible to melt the edge portion of the intermediate resin member 30 and join the outer peripheral portion of the intermediate resin member 30 and the edge portion of the through hole 22.

中間樹脂部材３０が接合されると、図５（Ａ）に示すように、蓋材３５を貫通孔２２に挿入して貫通孔２２を埋める。蓋材３５は、樹脂フランジ部２１（内槽パン２０）と同じ着色樹脂で構成されている。即ち、本実施形態では、樹脂フランジ部２１（内装パン２０）と中間樹脂部材３０と蓋材３５とが、全て同じ着色樹脂で構成されている。   When the intermediate resin member 30 is joined, the lid member 35 is inserted into the through hole 22 to fill the through hole 22 as shown in FIG. The lid member 35 is made of the same colored resin as the resin flange portion 21 (inner tank pan 20). That is, in this embodiment, the resin flange portion 21 (interior pan 20), the intermediate resin member 30, and the lid member 35 are all made of the same colored resin.

蓋材３５が貫通孔２２に挿入されると、図５（Ｂ）に示すように、超音波溶着装置８１のホーン８２を蓋材３５に押しつけて、蓋材３５を、樹脂フランジ部１２における貫通孔２２の内周面と、中間樹脂部材３０とに溶着する。これにより、金属フランジ部１２と樹脂フランジ部２１とが、中間樹脂部材３０及び蓋材３５を介して接合される。なお、図示はしないが、蓋材３５の外面には、突起が設けられ、この突起にホーン８２からの力が集中するようになっている。   When the lid member 35 is inserted into the through hole 22, as shown in FIG. 5B, the horn 82 of the ultrasonic welding device 81 is pressed against the lid member 35, and the lid member 35 is penetrated in the resin flange portion 12. It welds to the inner peripheral surface of the hole 22 and the intermediate resin member 30. As a result, the metal flange portion 12 and the resin flange portion 21 are joined via the intermediate resin member 30 and the lid member 35. Although not shown, a protrusion is provided on the outer surface of the lid member 35, and the force from the horn 82 is concentrated on this protrusion.

上述の如くして、金属フランジ部１２と樹脂フランジ部２１とを、周方向の複数箇所で接合することで、二槽式オイルパン１０が製造される。   As described above, the two-tank oil pan 10 is manufactured by joining the metal flange portion 12 and the resin flange portion 21 at a plurality of locations in the circumferential direction.

このように、本実施形態に係る金属フランジ部１２と樹脂フランジ部２１の接合方法では、レーザ光に対して透過性を有さない樹脂フランジ部２１に形成された貫通孔２２に、レーザ光に対して透過性を有する中間樹脂部材３０を挿入し、レーザ溶着にて中間樹脂部材３０と金属フランジ部１２とを接合する。そして、貫通孔２２を埋めた蓋材３５を中間樹脂部材３０及び樹脂部材２１に溶着する。即ち、本実施形態の接合方法では、レーザ溶着で金属に溶着可能な中間樹脂部材３０を金属フランジ部１２に接合してから、その中間樹脂部材３０に蓋材３５を介して樹脂フランジ部２１を接合する。本実施形態によれば、樹脂フランジ部２１がレーザ光に対して透過性を有さなくても、金属フランジ部１２と樹脂フランジ部２１とを接合することができる。しかも、中間樹脂部材３０の接合にレーザ溶着を用いたことで、金属フランジ部１２及び樹脂フランジ部２１の破壊を抑えつつ、中間樹脂部材３０と金属フランジ部１２の接合強度を高めることができる。   As described above, in the joining method of the metal flange portion 12 and the resin flange portion 21 according to the present embodiment, the laser light is transmitted to the through hole 22 formed in the resin flange portion 21 that is not transmissive to the laser light. The intermediate resin member 30 having transparency is inserted, and the intermediate resin member 30 and the metal flange portion 12 are joined by laser welding. Then, the lid member 35 filling the through hole 22 is welded to the intermediate resin member 30 and the resin member 21. That is, in the joining method of the present embodiment, the intermediate resin member 30 that can be welded to metal by laser welding is joined to the metal flange portion 12, and then the resin flange portion 21 is attached to the intermediate resin member 30 via the lid member 35. Join. According to the present embodiment, the metal flange portion 12 and the resin flange portion 21 can be joined even if the resin flange portion 21 does not have transparency to laser light. In addition, by using laser welding for joining the intermediate resin member 30, it is possible to increase the joining strength between the intermediate resin member 30 and the metal flange portion 12 while suppressing the destruction of the metal flange portion 12 and the resin flange portion 21.

また、本実施形態では、蓋材３５と、中間樹脂部材３０と、樹脂部材２１とは、全て同じ樹脂で構成されているので、蓋材３５と樹脂部材２１の接合強度及び蓋材３５と中間樹脂部材３０の接合強度を高めることが可能となる。しかも、樹脂部材２１と蓋材３５とが、同じ着色樹脂で構成されているので、接合後の樹脂部材２１と蓋材３５を区別しにくくすることができる。   Moreover, in this embodiment, since the lid | cover material 35, the intermediate resin member 30, and the resin member 21 are all comprised with the same resin, the joint strength of the lid | cover material 35 and the resin member 21, and the lid | cover material 35 and intermediate | middle. It becomes possible to increase the bonding strength of the resin member 30. Moreover, since the resin member 21 and the lid member 35 are made of the same colored resin, it is difficult to distinguish the resin member 21 and the lid member 35 after being joined.

また、本実施形態の二槽式オイルパン１０の製造方法によれば、金属フランジ部１２と樹脂フランジ部２１とが一体的に接合されるので、両フランジ部１２，２１を周方向の複数箇所で螺子止めする場合と比較して、両フランジ部１２，２１の固定の安定化が図られる。   Moreover, according to the manufacturing method of the two-tank type oil pan 10 of this embodiment, since the metal flange part 12 and the resin flange part 21 are integrally joined, both flange parts 12 and 21 are provided in multiple places of the circumferential direction. As compared with the case where the screw is fixed with the screw, the fixing of the flange portions 12 and 21 is stabilized.
