Description

本発明は、溶接時にワークの位置決めを行うための位置決めピンに関するものである。  The present invention relates to a positioning pin for positioning a workpiece during welding.

従来、特許文献１に記載のような高速度工具鋼ＳＫＨ５１からなる溶接用位置決めピンがあった。  Heretofore, there have been welding positioning pins made of high-speed tool steel SKH51 as described in Patent Document 1.

実開平０６−００５７７９号公報Japanese Utility Model Publication No. 06-005779

前記のものでは、溶接時の溶接電流によって、位置決めピンが磁化され、鉄粉やスパッタ等が位置決めピンに吸着され、エアーブローにて吹き飛ばすことができないことがあり、そのような場合、溶接終了後にワークを取外すのに吸着した鉄粉やスパッタ等が邪魔になりワークの取外しに手間が掛かるという問題があった。  In the above, the positioning pin is magnetized by the welding current at the time of welding, and iron powder, spatter, etc. are attracted to the positioning pin and may not be blown away by air blow. There has been a problem that it takes time to remove the work because the iron powder or spatter, etc. adsorbed in the process of removing the work become an obstacle.

本発明は、前記の問題を解決し、溶接電流によって磁化される恐れがなく、磁化されることによる鉄粉やスパッタ等が吸着されることがなくワークの取外しが容易にできる位置決めピンを提供することを目的になされたものである。  The present invention provides a positioning pin that solves the above-described problems and that can be easily removed without the possibility of being magnetized by a welding current and without adsorbing iron powder, spatter, or the like due to magnetization. It was made for the purpose.

上記課題を解決するためになされた本発明の位置決めピンは、固定部と固定部の上部に形成された挿通突起とからなる位置決めピンにおいて、位置決めピンの母材を非磁性金属製とし、該母材に非磁性メッキ被膜を施すとともに、メッキ被膜の上に潤滑剤のコーティング層を形成したことを特徴とするものである。  The positioning pin of the present invention made to solve the above problems is a positioning pin comprising a fixed portion and an insertion protrusion formed on the upper portion of the fixed portion, and the base material of the positioning pin is made of a non-magnetic metal. A nonmagnetic plating film is applied to the material, and a coating layer of a lubricant is formed on the plating film.

前記母材を銅又は銅合金製とするとともに、前記メッキ被膜を無電解ニッケルメッキ被膜としたことものであることが好ましく、これを請求項２に係る発明とする。  Preferably, the base material is made of copper or a copper alloy, and the plating film is an electroless nickel plating film, which is an invention according to claim 2.

本発明では、位置決めピンの母材を非磁性金属製とし、該母材に非磁性メッキ被膜を施すとともに、メッキ被膜の上に潤滑剤のコーティング層を形成したので、位置決めピンが磁化されて鉄粉やスパッタ等が吸着することがなく、また磁化以外の理由によって鉄粉やスパッタ等が付着しても潤滑剤のコーティング層によって鉄粉やスパッタ等の付着力が弱いので、簡単に鉄粉やスパッタ等を剥がすことができ、ワークの取外しが容易にできるという効果がある。  In the present invention, the base material of the positioning pin is made of a non-magnetic metal, and the base material is coated with a non-magnetic plating film, and a lubricant coating layer is formed on the plating film. Even if iron powder or spatter adheres for reasons other than magnetization, the adhesion of iron powder or spatter is weak due to the coating layer of the lubricant. There is an effect that the spatter etc. can be peeled off and the work can be easily removed.

本発明の一実施例を示す正面図である。It is a front view which shows one Example of this invention. 図１の平面図である。It is a top view of FIG. 位置決めピンの被膜の説明図である。It is explanatory drawing of the film of a positioning pin.

以下、本発明の好ましい実施の形態について図１乃至図４に基づいて説明する。  Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS.

図１乃至図３は本発明の一実施例を示すものであり、１は、上端にフランジ２を設けた固定部３と、該固定部３のフランジ２の上面から突設した、図示されていないワークの位置決め孔に挿通されてワークを位置決めする挿通突起４とから形成された非磁性体のベリリウム銅等の銅、銅合金からなる位置決めピンであり、位置決めピン１の固定部３の下部には図示されていない溶接機等に取付けるためのねじ５が螺刻されるとともに、挿通突起４の上部には先細状の案内部６が設けられている。  FIGS. 1 to 3 show an embodiment of the present invention. Reference numeral 1 denotes a fixed portion 3 having a flange 2 at its upper end, and a protrusion projecting from the upper surface of the flange 2 of the fixed portion 3. This is a positioning pin made of a copper or copper alloy such as beryllium copper, which is a non-magnetic material, formed from an insertion protrusion 4 which is inserted into a positioning hole of a workpiece that is not positioned, and is positioned below the fixing portion 3 of the positioning pin 1 A screw 5 for mounting on a welding machine or the like (not shown) is screwed, and a tapered guide 6 is provided on the upper part of the insertion projection 4.

前記位置決めピン１には、図３に示すように、母材７の表面硬度を上げるため、非磁性のメッキ被膜である無電解ニッケルメッキのメッキ被膜８が施されているとともに、メッキ被膜８上には超極圧潤滑剤、極圧潤滑剤等の潤滑剤のコーティング層９が形成されている。尚、必要に応じてメッキ被膜８施した後に熱処理をして表面硬度を上げても良い。  As shown in FIG. 3, the positioning pin 1 is provided with an electroless nickel plating plating film 8 which is a nonmagnetic plating film in order to increase the surface hardness of the base material 7. A coating layer 9 of a lubricant such as an extreme pressure lubricant or an extreme pressure lubricant is formed thereon. If necessary, heat treatment may be performed after the plating film 8 is applied to increase the surface hardness.

以上のように本発明では、位置決めピン１の母材７を非磁性金属製とし、該母材７に非磁性メッキ被膜８を施すとともに、メッキ被膜８の上に潤滑剤のコーティング層９を形成したので、位置決めピン１が磁化されて鉄粉やスパッタ等が吸着することがなく、また磁化以外の理由によって鉄粉やスパッタ等が付着しても潤滑剤のコーティング層９によって鉄粉やスパッタ等の付着力が弱いので、簡単に鉄粉やスパッタ等を剥がすことができ、ワークの取外しが容易にできる  As described above, in the present invention, the base material 7 of the positioning pin 1 is made of a nonmagnetic metal, and the base material 7 is coated with the nonmagnetic plating film 8 and the lubricant coating layer 9 is formed on the plating film 8. Therefore, the positioning pin 1 is not magnetized and iron powder or spatter is not adsorbed, and even if iron powder or spatter adheres for reasons other than magnetization, the lubricant coating layer 9 causes iron powder or spatter or the like to adhere. Adhesion is weak, so iron powder, spatter, etc. can be easily peeled off, and work can be easily removed
