【発明の詳細な説明】 （産業上の利用分野） 本発明は、４箇所以上の貫通する取付穴を備える板状部
材同士、或いは板状部材と非板状部材とを溶接結合する
構造物の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure in which plate-shaped members having four or more mounting holes penetrating each other, or a plate-shaped member and a non-plate-shaped member are welded to each other. It is about improvement.

There is a back plate which is applied to the drum brake disclosed in Japanese Patent Laid-Open No. 62-69634. As shown in FIGS. 2 to 6, two plate-shaped press-formed products are appropriately spot-welded or riveted. Are combined with each other.

Reference numeral 2 is a relatively thick reinforcing plate, which is an anchor portion 2a with which the brake shoe abuts from a mounting portion 2a (see FIG. 5) to the knuckle N of the vehicle, which is a portion requiring the strength of the back plate
Only the range up to is reinforced, and the material of the entire back plate is reduced.

1d, two holes 1e for fastening the anchor member, a hole 1f through which the cable loosely fits, and two holes 1g for holding the pair of brake shoes on the back plate body 1 are formed. Moreover, raised portions 1i for supporting the brake shoes are formed at six positions inside the outer peripheral flange 1h forming the labyrinth with the brake drum.

(See FIG. 6) to avoid interference with the root R of the spindle S. The protrusion 2j is formed for the purpose of preventing inward deformation when the mounting hole 2d is punched out. Incidentally, 2e is an anchor member mounting hole, and 2f is a cable insertion hole.
（発明が解決しようとする課題） しかしながら上述した従来のものはバックプレート本体
１と補強板２を結合する際に下記のような問題点があっ
た。(Problems to be Solved by the Invention) However, the above-described conventional device has the following problems when the back plate body 1 and the reinforcing plate 2 are coupled.

準寸法Ａとした例である。That is, FIGS. 7 (a) and 7 (b) show a conventional method of connecting the back plate body 1 and the reinforcing plate 2 to each other.
In the method shown in FIG. 2 (a), the knuckle N is attached to both the mounting hole 1d formed in the back plate body 1 and the mounting hole 2d formed in the reinforcing plate 2.
In this example, the reference dimension A is slightly larger than the diameters of bolts and rivets for fastening to.

差を見込んで位置決め用ピンＰの外径Ｄを可成り小さい
設計しなければならないため、その分ずれが生じる為に
後工程でリーマ通し等による修正加工を要するという問
題点があった。As a method of machining these mounting holes 1d and 2d, a method of machining the back plate body 1 and the reinforcing plate 2 after they are joined by a drill or a method of punching them with a press in advance and joining them together later. Two types were adopted. In the former case, the machining time is long and uneconomical. In the latter case, the outer diameter D of the positioning pin P must be designed to be quite small in consideration of the pitch tolerance of the eight mounting holes 1d and 2d. Therefore, there is a problem that a correction process such as through a reamer is required in a subsequent process because the shift is generated by that amount.
また第７図（ロ）は上記の課題を解決しようとするもの
で、これはバックプレート本体１の取付穴1dは基準寸法
の穴径Ａのままであるが、補強板２の取付穴2dの穴径Ｂ
を多少大きくしたものである。Further, FIG. 7 (B) is intended to solve the above-mentioned problem, in which the mounting hole 1d of the back plate body 1 is still the standard size hole diameter A, but the mounting hole 2d of the reinforcing plate 2 is Hole diameter B
Is a little larger.

ばならない。In this case, the mounting holes 1d and 2d of the back plate body 1 and the reinforcing plate 2 may be punched by a press in advance, but the positioning pin P must be stepped.
その為、段付き面のエッジ部がへたり易く補強板２の取

嵌合せずに傾いた状態でバックプレート本体１を結合す
る作業を行ってしまうという課題が残されていた。Therefore, not only is it difficult to attach the reinforcing plate 2 to the edge portion of the stepped surface, but also the work for joining the back plate body 1 in a tilted state without the pin P being securely fitted. There was a problem that it would end up.

In a structure in which these holes are superposed by being guided by a pin jig and the plurality of members are welded and joined, at least one of the mounting holes formed in the one member is fitted into the pin jig. In addition, the other mounting holes of one member are distributed and formed with a hole diameter slightly larger than the reference dimension, and the mounting hole of the other member corresponding to this is at least other than the reference dimension mounting hole of the one member. One member has a standard size for fitting with a pin jig, and the other mounting holes of the other member are formed with a hole diameter slightly larger than the standard size so that a plurality of members are joined.

Therefore, when designing the pin outer diameter of the positioning pin jig, the expected amount of pitch tolerance of the mounting holes is Only half of the conventional method is required. Therefore, even if all the mounting holes are punched by a press, the displacement between the back plate and the reinforcing plate is reduced.
又、位置決め用ピン治具のピンをストレートにできるの
で作業が楽になり、しかも誤作業が起きにくくなる。In addition, since the pins of the positioning pin jig can be straightened, the work is easy, and moreover, erroneous work is less likely to occur.

The mounting hole 1d of B is distributed and formed, and the mounting hole 2d of the reinforcing plate 2 which is the other member corresponding to the mounting hole 1d of B is set to a mounting hole 2d of a diameter B which is slightly larger than the mounting hole 1d of the reference dimension A and is large. At least one place of the mounting hole 1d having the diameter B is punched by a press in advance so that the mounting hole 2d having the reference dimension A is formed. And the standard dimension A of both members 1 and 2
The mounting holes 1d and 2d of the
, And appropriate parts of both members 1 and 2 are integrally connected by means such as welding.

工が不要となるという効果が得られる。(Effects of the Invention) As described above, according to the present invention, the mounting holes having the standard dimensions are distributed and formed in the plurality of members to be joined. Therefore, when designing the outer diameter of the pin P of the positioning pin jig, the mounting holes are designed. The expected amount of pitch tolerance is half that of the conventional model. Therefore, even if all the mounting holes are punched by a press, the displacement between the back plate 1 and the reinforcing plate 2 is small, and the effect of correcting the mounting holes is unnecessary.
