(57) [Summary] [PROBLEMS] The present invention is to prevent a chip from shifting when a gun is pressurized. A U-shaped arm for mounting a gun for spot welding, in which a desired strength is obtained by inserting a special steel 3 into an inner diameter 2 of an aluminum round officer 1 and bending it.
Description
【０００１】[0001]
本考案は、アルミ丸管の中に特殊鋼を入れ、一緒に曲げるスポット溶接用ガン 取り付け用Ｕ型アームに関するものである。 The present invention relates to a U-arm for spot welding gun mounting, in which special steel is put in an aluminum round tube and bent together.
【０００２】[0002]
この種のスポット溶接用ガン取り付け用Ｕ型アームは、アルミ平角棒材料を各 種形状に切削、曲げ、加工によって制作されていた。 This type of U-shaped arm for spot welding gun mounting was manufactured by cutting, bending, and processing aluminum rectangular bar material into various shapes.
【０００３】[0003]
ところで、上記のアルミ平角棒による場合には、ガンを加圧時に、アルミの材 料特性から、引っ張り強さ、ブリネル硬さが足りない事で、ガン加圧時にチップ 上下のズレが生じたりする。 By the way, in the case of the above-mentioned aluminum flat bar, when the gun is pressurized, due to the lack of tensile strength and Brinell hardness due to the material properties of aluminum, the tip may shift up and down when the gun is pressurized. .
【０００４】 この考案は、従来の技術の有するこのような問題点に鑑みてなされたものであ り、その目的とするところはアルミ丸管の内径に特殊鋼を入れる事により所望の 強度が得られ、なおかつ重量を軽減することが可能になるスポット溶接用ガン取 り付け用Ｕ型アームを提供しようとするものである。[0004] The present invention has been made in view of such problems of the prior art, and the purpose is to obtain a desired strength by inserting special steel into the inner diameter of an aluminum round tube. An object of the present invention is to provide a U-shaped arm for mounting a gun for spot welding that can reduce the weight.
【０００５】[0005]
上記の目的を達成する為に、この考案におけるスポット溶接用のガン取り付け 用Ｕ型アームは、アルミ丸管の内径に特殊鋼を曲げる中心部分まで入れたもので ある。 In order to achieve the above object, the U-shaped arm for gun welding for spot welding according to the present invention is formed by inserting a special steel into the inner diameter of an aluminum round pipe up to a central portion where the special steel is bent.
【０００６】 そして、特殊鋼を使用した事を特徴とするものである。[0006] The invention is characterized in that special steel is used.
【０００７】[0007]
アルミ丸管内側に、特殊鋼をいれ、一緒に曲げた時、アルミ管への影響は少な く、アルミ管と特殊鋼とが密着し強度を有するスポット溶接用ガン取り付け用Ｕ 型アームの構造である。 When special steel is placed inside the aluminum round tube and bent together, the effect on the aluminum tube is small. is there.
【０００８】 これにより、アルミ管と特殊鋼との一体化が確実に可能となり、またアルミ管 と特殊鋼とは、別体からなるので、これらの材料は、自由に選択する事が出来、 強度のある特殊鋼を核として、密着性のよいアルミ管とした場合には適正なスポ ット溶接が得られる。[0008] This makes it possible to reliably integrate the aluminum pipe and the special steel, and since the aluminum pipe and the special steel are formed separately, these materials can be freely selected. If a special steel with nuclei is used as the core and an aluminum tube with good adhesion is obtained, appropriate spot welding can be obtained.
【０００９】[0009]
図面を参照してこの考案の実施例について説明をする。 An embodiment of the present invention will be described with reference to the drawings.
【００１０】 図１において１はアルミ管肉厚部であり２はアルミ管の空洞部３は丸鋼材部で ある。In FIG. 1, reference numeral 1 denotes a thick part of an aluminum pipe, 2 denotes a hollow part of the aluminum pipe, and 3 denotes a round steel part.
【００１１】 そして、アルミ管部１、に特殊鋼３を挿入し形成されている。The special steel 3 is inserted into the aluminum pipe 1 and formed.
【００１２】 従って、特殊鋼３をアルミ管部１に挿入し形成したアルミ空洞部２に挿入した状 態でＵ型に曲げられる。曲げた事によるひずみは局部的であって周囲への影響は 少なくアルミ管１と特殊鋼３のひずみがほとんどなくスポット溶接用Ｕ型アーム の構造が得られる。Therefore, the special steel 3 is bent into a U-shape while being inserted into the aluminum cavity 2 formed by inserting the special steel 3 into the aluminum pipe 1. The distortion due to bending is local and has little effect on the surroundings, so that there is almost no distortion of the aluminum pipe 1 and the special steel 3, and a U-shaped arm for spot welding can be obtained.
【００１３】 そして、特殊後部３をアルミ管部１に挿入し形成したＵ型アームにした時、従 来のスポット溶接用ガン取り付け用Ｕ型アームと比較して強度が３０％以上多く 得る事が出来、スポット溶接用ガン取り付け用Ｕ型アームとして広範囲で十分使 用できる事が立証された。When the special rear portion 3 is formed into a U-shaped arm formed by being inserted into the aluminum pipe portion 1, the strength can be increased by 30% or more as compared with the conventional U-shaped arm for mounting a gun for spot welding. It was proved that it could be used in a wide range as a U-arm for mounting a gun for spot welding.
【００１４】 また、アルミ管部１と特殊鋼部３とは別体となるのでこれらの材料は、強度を 考慮して自由に選択する事が出来るが、強度のある特殊鋼３、軽さを重視するア ルミ管３とした場合には、上記のことから３０％以上多くの強度が得られ適切な スポット溶接が遂行できるものであった。Further, since the aluminum pipe portion 1 and the special steel portion 3 are separate bodies, these materials can be freely selected in consideration of the strength. In the case where the aluminum tube 3 was emphasized, 30% or more strength was obtained from the above, and appropriate spot welding could be performed.
【００１５】[0015]
この考案によると、アルミ管部１の空洞部分２に特殊鋼３を挿入したものである 。又、周囲へのひずみの影響は少なく所望の強度を有するスポット溶接用ガン取 り付け用Ｕ型アームの構造が得られるものである。 According to this invention, the special steel 3 is inserted into the hollow part 2 of the aluminum pipe part 1. Further, the structure of the U-shaped arm for mounting the gun for spot welding having a desired strength with little influence of the distortion on the surroundings can be obtained.
