本考案は薄板を対象とした重ね抵抗溶接物の位置決め構造に関する。 The present invention relates to a lap resistance welding object positioning structure for a thin plate.
【０００２】[0002]
従来、薄板を対象とした重ね抵抗溶接物の位置決め構造には一方の溶接物とし ての小物部品に設けた位置決め用凸部を他方の溶接物としての母材の位置決め用 穴部に挿入して溶接物の位置決めを行うものがあった。 Conventionally, in the positioning structure of lap resistance welded products for thin plates, the positioning projections provided on the small parts as one weldment are inserted into the positioning holes of the base material as the other welded product. There was a thing which positions a welded object.
【０００３】 図５は従来例の重ね抵抗溶接物の位置決め構造を示す斜視図であり、図６は図 ５のＡ−Ａ断面矢視図である。Ｌ字状の小物部品１には図６に示すように位置決 め用凸部２とプロジェクション３とがそれぞれ高さＨ2 ，Ｈ1 で設けてある。 又、板厚Ｈ3 の母材４には小物部品１の凸部２に対応して貫通した穴部５が設 けてある。高さＨ1 ，Ｈ2 と板厚Ｈ3 との間にはＨ1 ＜Ｈ2 ≦Ｈ3 の関係がある 。溶接の際、小物部品１は凸部２を母材４の穴部５に挿入し、母材４に対して位 置決めされる。FIG. 5 is a perspective view showing a positioning structure of a conventional lap resistance welded product, and FIG. 6 is a sectional view taken along the line AA of FIG. As shown in FIG. 6, the L-shaped small component 1 is provided with positioning projections 2 and projections 3 at heights H 2 and H 1 , respectively. Further, the base material 4 having the plate thickness H 3 is provided with a hole portion 5 penetrating corresponding to the convex portion 2 of the small component 1. There is a relationship of H 1 <H 2 ≦ H 3 between the heights H 1 and H 2 and the plate thickness H 3 . At the time of welding, the small component 1 is positioned with respect to the base material 4 by inserting the convex portion 2 into the hole 5 of the base material 4.
【０００４】 溶接後、母材４の穴部５には凹部が生じる。たとえ、Ｈ2 ≒Ｈ3 としたとして も穴部５には抜ダレやバリ取りによる面取り等があって凹部を生じてしまう。従 って、母材４が装置のカバー等であり、小物部品１を溶接した面の裏面に塗装を 施す場合には、パテにて凹部を埋めてから塗装する必要があった。After welding, a recess is formed in the hole 5 of the base material 4. Even if H 2 ≉H 3 , the hole 5 has a concave portion due to the chamfering due to the sagging and deburring. Therefore, when the base material 4 is the cover of the apparatus or the like and the back side of the welded surface of the small component 1 is to be coated, it is necessary to fill the concave portion with putty before coating.
【０００５】 なお、本位置決め構造は他の重ね抵抗溶接法であるスポット溶接法でも用いら れている。The present positioning structure is also used in the spot welding method which is another lap resistance welding method.
【０００６】[0006]
従来の重ね抵抗溶接物の位置決め構造にあっては、他方の溶接物としての母材 が装置のカバー等であり、一方の溶接物としての小物部品を溶接した面の裏面に 塗装を施す場合には溶接後、凹部を埋める工程を必要とし、その作業は経験と感 に頼る作業であり多大の加工時間を必要とするという問題があった。 本考案は溶接後、位置決め部に凹部を生じない重ね抵抗溶接物の位置決め構造 を提供することを目的としている。 In the conventional positioning structure for lap resistance welded products, the base material as the other welded product is the cover of the device, etc., and when coating the back surface of the welded surface of the small parts as one welded product. Has a problem in that it requires a step of filling the recess after welding, which requires a lot of processing time because it depends on experience and feeling. An object of the present invention is to provide a positioning structure for a lap resistance welded product in which no recess is formed in the positioning portion after welding.

【００１２】 次に溶接時の作用について説明する。先ず小物部品３２の凸部３３を母材３５ の穴部３６に挿入して母材３５に対する小物部品３２の位置決めを行う。次に母 材３５を電極３１の上に乗せて図示せぬレバーを踏むと、電極３０が矢印方向へ 移動して電極３１とともに小物部品３２と母材３５とを加圧する。加圧力が設定 値に達すると電極３０から電極３１に向って電流が流れる。この時、電流は凸部 ３３及びプロジェクション３４に集中し、凸部３３及びプロジェクション３４の 周辺部に溶けて小物部品３２と母材３５とを溶接する。これにより溶接部間の浮 き上ることはない。 なお、凸部３３の周辺部も溶けると述べたが、これは凸部３３，プロジェクシ ョン３４，穴部３６との関係を示すＨ1 ＜Ｈ2 ≦Ｈ1 ＋Ｈ3 からわかるようにＨ 2 ≒Ｈ1 ＋Ｈ3 のときはＨ2 ＞Ｈ3 となり、凸部３３の高さＨ2 が穴部３６の深 さＨ3 より大となるからである。 なお、本実施例では位置決め用凸部とプロジェクションとはプレスによる打出 し加工で同時加工できる。そして溶接時には溶接電極に対して打出した凸部の凹 部を目安にしてセットすることによりプロジェクションを均等に加圧できる。 又、小物部品に位置決め用凸部とプロジェクションとを設けたが、穴部として のめくら穴とプロジェクションとを設け、母材に凸部を設けてもよい。その際の プロジェクション，凸部の高さＨ1 ，Ｈ2 と穴部の深さＨ3 との関係は本実施例 と同じである。Next, the operation during welding will be described. First, the convex portion 33 of the small component 32 is inserted into the hole 36 of the base material 35 to position the small component 32 with respect to the base material 35. Next, when the base material 35 is placed on the electrode 31 and a lever (not shown) is stepped on, the electrode 30 moves in the direction of the arrow to pressurize the small component 32 and the base material 35 together with the electrode 31. When the applied pressure reaches the set value, a current flows from the electrode 30 toward the electrode 31. At this time, the electric current is concentrated on the convex portion 33 and the projection 34, melts in the peripheral portion of the convex portion 33 and the projection 34, and welds the small component 32 and the base material 35. This prevents the welds from floating. Although it has been stated that the peripheral portion of the convex portion 33 also melts, this indicates the relationship between the convex portion 33, the projection 34, and the hole 36.1<H2≤H1+ H3As you can see from H 2 ≒ H1+ H3When is H2> H3And the height H of the convex portion 332Is the depth H of the hole 363Because it will be larger. In this embodiment, the positioning convex portion and the projection can be simultaneously formed by stamping. Then, at the time of welding, the projections can be evenly pressed by setting the concave portions of the convex portions punched against the welding electrode as a guide. Further, although the positioning convex portion and the projection are provided on the small component, the blind hole and the projection as the hole portions may be provided, and the convex portion may be provided on the base material. Projection at that time, height H of the convex portion1, H2And hole depth H3The relationship with is the same as in this embodiment.
【００１３】[0013]
本考案は以上説明したように構成されているので以下に記載される効果を奏す る。 他方の溶接物の位置決め用穴部をめくら穴にしたことにより、溶接後位置決め 部に生じていた凹部がなくなり塗装を施す場合に行っていた凹部を埋める工程を 不要とする。 又、位置決め構造及び溶接部は溶接電極の範囲内に設けたことにより、共に溶 接され、穴部と凸部との製造誤差を吸収するとともに溶接物間の浮き上りを防止 できる。 Since the present invention is configured as described above, it has the following effects. By making the positioning hole of the other welded product a blind hole, the recess that had been created in the positioning part after welding disappears and the step of filling the recess that was performed when painting is unnecessary. Further, since the positioning structure and the welded portion are provided within the range of the welding electrode, they are welded together to absorb the manufacturing error between the hole and the protrusion and prevent the floating of the welded material.
