Description
本発明は、表面が平面である２枚の板状のワークの接合位置決め方法及び接合構造に関する。さらに詳細には、２枚の板材（ワーク）を接合するための穴や突出部等を外側面に表すことなく接合する方法及び接合構造に関する。 The present invention relates to a joining positioning method and a joining structure of two plate-shaped workpieces having a flat surface. More specifically, the present invention relates to a method and a joining structure for joining two plate materials (workpieces) without showing holes, protrusions, or the like on the outer surface.
表面が平面である２枚の板状のワークにおける平面の一部を合わせて、例えばスポット溶接などを行う場合、一方のワークに対して他方のワークを動かないように位置決め固定する必要がある。この場合、例えば一方のワークの表面に、位置決め用の突出部が形成されるものである（例えば、特許文献１参照）。 When a part of the flat surface of two plate-shaped workpieces having a flat surface is combined and spot welding is performed, for example, it is necessary to position and fix the other workpiece to one workpiece so as not to move. In this case, for example, a protrusion for positioning is formed on the surface of one of the workpieces (see, for example, Patent Document 1).
前記特許文献１の記載によれば、板状の一方のワークの表面に突起部を形成し、他方のワークの端縁を前記突起部に当接することによって、一方のワークに対して他方のワークの位置決めを行う。又は、前記突起部の径に対応した穴を他方のワークに形成する。そして、前記穴に突起部を嵌合することにより、一方のワークと他方のワークとの位置決めを行う構成である。 According to the description of Patent Document 1, a protrusion is formed on the surface of one plate-shaped work, and the edge of the other work is brought into contact with the protrusion so that the other work is opposed to the other work. Positioning. Alternatively, a hole corresponding to the diameter of the protrusion is formed in the other work. Then, by fitting the protrusion into the hole, the one work and the other work are positioned.
したがって、前記構成によれば、一方のワークの表面に突起部を形成した構成であるから、当該ワークの裏面に、例えば凹部等を生じることがなく、裏面の外観を大きく損なうことはない。しかし、他方のワークを表面に重ねて位置決めした場合には、前記突出部が外側面に表れる。したがって、外観の向上を図ることは難しいものであった。 Therefore, according to the above configuration, since the protrusion is formed on the front surface of one of the works, for example, a recess or the like is not formed on the back surface of the work, and the appearance of the back surface is not significantly impaired. However, when the other work is placed on the surface and positioned, the protrusion appears on the outer surface. Therefore, it was difficult to improve the appearance.
本発明は、上記のごとき問題に鑑みて、板状の一方のワークと他方のワークとを重ねて位置決め接合した場合、位置決め接合部の構成が外観に表れることのないようにして、外観の向上を図ろうとするものである。 In view of the above problems, the present invention improves the appearance by preventing the configuration of the positioning joint portion from appearing in the appearance when the plate-shaped one work and the other work are overlapped and bonded. It is an attempt to achieve.
したがって、本発明は、表面が平面である２枚の板材の接合位置決め方法であって、
（ａ）一方の板材の表面に、前記表面に垂直であって前記表面に沿う方向の位置決めを行う位置決め面を備えた位置決め凹部を、中央部に円錐形状の盛り上がり部を有するよう形成する工程、
（ｂ）他方の板材の表面に、前記位置決め面に接合する位置決め接合面を外周面とする円筒形の位置決め凸部を形成する工程、
（ｃ）前記位置決め凹部の位置決め面と前記位置決め凸部の位置決め接合面とを接合して、前記一方の板材の表面と前記他方の板材の表面とを接合する工程、
の各工程を備えている。
Therefore, the present invention is a method for joining and positioning two plates having a flat surface.
(A) A step of forming a positioning recess on the surface of one of the plate materials, which is perpendicular to the surface and has a positioning surface for positioning in a direction along the surface, so as to have a conical ridge in the center .
(B) A step of forming a cylindrical positioning convex portion having a positioning joint surface to be joined to the positioning surface as an outer peripheral surface on the surface of the other plate material.
(C) A step of joining the positioning surface of the positioning recess and the positioning joint surface of the positioning protrusion to join the surface of the one plate material and the surface of the other plate material.
Each process is equipped.
また、表面が平面である２枚の板材の接合構造であって、一方の板材の表面に、前記表面に垂直に形成され前記表面に沿う方向の位置決めを行う位置決め面と中央部に円錐形状に形成された盛り上がり部とを有する位置決め凹部を備え、他方の板材の表面に、位置決め接合面を外周面として円筒形に形成された位置決め凸部を備え、前記位置決め凹部の位置決め面と前記位置決め凸部の位置決め接合面とを接合した状態において、前記一方の板材の表面と前記他方の板材の表面とを接合してある。 Further, it is a joint structure of two plate materials having a flat surface, and has a conical shape at the center and a positioning surface formed perpendicular to the surface of one plate material to perform positioning in a direction along the surface. A positioning recess having a formed raised portion is provided, and a positioning convex portion formed in a cylindrical shape with a positioning joint surface as an outer peripheral surface is provided on the surface of the other plate material, and the positioning surface of the positioning recess and the positioning convex portion are provided. The surface of the one plate material and the surface of the other plate material are joined in a state where the positioning joint surface of the above is joined.
本発明によれば、一方の板材と他方の板材とを接合位置決めした構成が外観に表れない。したがって、２枚の板材を接合した構造においての外観向上を図ることができる（すなわち、接合部分が目立つことがない）。 According to the present invention, the configuration in which one plate material and the other plate material are joined and positioned does not appear in the appearance. Therefore, it is possible to improve the appearance in the structure in which the two plate materials are joined (that is, the joined portion is not conspicuous).
以下、図面を用いて、本発明の実施形態について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
本実施形態においては、一方の板材Ａの表面Ａ１（図１（Ｂ）においては上面）に、表面に沿う方向（図１ＢにおいてのＸ方向（左右方向）、Ｙ方向（紙面に垂直な方向））の位置決めを行う位置決め面Ａ２を備えた位置決め凹部Ａ３を形成する。前記位置決め面Ａ２は、前記表面Ａ１に対して垂直であって円形に形成してある。前記位置決め凹部Ａ３は（板面上方から見ると）環状であって、底面Ａ４は表面Ａ１と平行な平面に形成してある。そして、前記位置決め凹部Ａ３の中央部には円錐形状の盛上がり部Ａ５が形成してある。この盛上がり部Ａ５は、表面Ａ１と同一高さ、又は表面Ａ１よりも突出した高さに形成することができる。なお、盛上がり部Ａ５は、表面Ａ１よりも低く形成することも可能である。 In the present embodiment, the direction along the surface (X direction (left-right direction) and Y direction (direction perpendicular to the paper surface) in FIG. 1B) along the surface A1 (upper surface in FIG. 1B) of one plate material A. ) Is formed as a positioning recess A3 having a positioning surface A2 for positioning. The positioning surface A2 is perpendicular to the surface A1 and is formed in a circular shape. The positioning recess A3 is annular (when viewed from above the plate surface), and the bottom surface A4 is formed on a plane parallel to the surface A1. A conical raised portion A5 is formed in the central portion of the positioning recess A3. The raised portion A5 can be formed at the same height as the surface A1 or at a height protruding from the surface A1. The raised portion A5 can be formed lower than the surface A1.
前記盛上がり部Ａ５は、位置決め凹部Ａ３を形成する際に、位置決め凹部Ａ３部分の肉の逃げ部として、形成される。したがって、位置決め凹部Ａ３における位置決め面Ａ２及び底面Ａ４の精度向上を図ることができるものである。また、板材Ａにおける表面Ａ１の平坦度の向上を図ることができる。 The raised portion A5 is formed as a relief portion for the meat of the positioning recess A3 when the positioning recess A3 is formed. Therefore, it is possible to improve the accuracy of the positioning surface A2 and the bottom surface A4 in the positioning recess A3. Further, the flatness of the surface A1 of the plate material A can be improved.
上記位置決め面Ａ２や位置決め凹部Ａ３は、板材Ａの表面Ａ１にコイニング加工を行うことによって形成されるものである。位置決め凹部Ａ３のコイニング加工を行う金型（図示省略）は、パンチプレスに装着して使用されるパンチ金型である。そして、パンチ金型におけるパンチボディの先端面に、前記位置決め凹部Ａ３を板材Ａの表面へ転写するための転写部（突出部）を備えた構成である。すなわち、パンチ金型の全体的構成は、転写部の構成が異なるのみであって、その他の構成は、一般的なコイニング金型（刻印金型）と同様の構成である。したがって、金型の全体的構成についての詳細な説明は省略する。 The positioning surface A2 and the positioning recess A3 are formed by performing a coining process on the surface A1 of the plate material A. The die (not shown) for performing the coining process of the positioning recess A3 is a punch die attached to a punch press and used. Further, the tip surface of the punch body in the punch die is provided with a transfer portion (projection portion) for transferring the positioning recess A3 to the surface of the plate material A. That is, the overall configuration of the punch die is different only in the configuration of the transfer portion, and the other configurations are the same as those of the general coining die (engraving die). Therefore, a detailed description of the overall configuration of the mold will be omitted.
前記板材Ａと接合する他方の板材Ｂの表面Ｂ１（図１（Ａ）においては下面）には、前記位置決め凹部Ａ３に嵌合する位置決め凸部Ｂ２が突出形成してある。この位置決め凸部Ｂ２は、前記特許文献１に記載の金型を使用することによって形成されるものである。前記位置決め凸部Ｂ２は、中央部に凹部Ｂ３を形成し、かつ外周に環状の溝Ｂ４を形成することによって突出形成されたものであって、円筒形である。そして、前記表面Ｂ１より突出してある。 On the surface B1 (lower surface in FIG. 1A) of the other plate material B to be joined to the plate material A, a positioning convex portion B2 that fits into the positioning recess A3 is formed so as to project. The positioning convex portion B2 is formed by using the mold described in Patent Document 1. The positioning convex portion B2 is formed by forming a concave portion B3 in the central portion and forming an annular groove B4 on the outer periphery thereof, and is cylindrical. And it protrudes from the surface B1.
前記位置決め凸部Ｂ２の外径は、前記位置決め凹部Ａ３に適正に嵌合する外径に形成してある。そして、前記位置決め凸部Ｂ２の突出寸法は、板材Ａにおける前記位置決め凹部Ａ３の深さよりも小さな寸法に形成してある。 The outer diameter of the positioning protrusion B2 is formed to be an outer diameter that properly fits into the positioning recess A3. The protruding dimension of the positioning convex portion B2 is formed to be smaller than the depth of the positioning concave portion A3 in the plate material A.
上記構成において、一方の板材Ａにおける位置決め凹部Ａ３に、他方の板材Ｂにおける位置決め凸部Ｂ２を嵌合すると、位置決め凹部Ａ３における位置決め面Ａ２と位置決め凸部Ｂ２の外周面である接合面Ｂ５とが接合する。そして、一方の板材Ａの表面Ａ１と、他方の板材Ｂの表面Ｂ１とが接合することになる。 In the above configuration, when the positioning convex portion B2 in the other plate material B is fitted to the positioning concave portion A3 in one plate material A, the positioning surface A2 in the positioning concave portion A3 and the joint surface B5 which is the outer peripheral surface of the positioning convex portion B2 are formed. Join. Then, the surface A1 of one plate material A and the surface B1 of the other plate material B are joined.
上述のように、一方の板材Ａの表面Ａ１と他方の板材Ｂの表面Ｂ１とを接合すると、一方の板材Ａにおける位置決め凹部Ａ３の位置決め面Ａ２と、他方の板材Ｂにおける位置決め凸部Ｂ２の接合面Ｂ５とが接合する。したがって、一方の板材Ａの表面Ａ１の複数箇所に位置決め凹部Ａ３を形成し、他方の板材Ｂの表面Ｂ１の対応した複数箇所に位置決め凸部Ｂ２を形成する。そして、両方の板材Ａ，Ｂの表面Ａ１，Ｂ１を接合することにより、両方の板材Ａ，Ｂは位置ずれを生じることなく接合することができる。 As described above, when the surface A1 of one plate material A and the surface B1 of the other plate material B are joined, the positioning surface A2 of the positioning recess A3 in one plate material A and the positioning convex portion B2 in the other plate material B are joined. The surface B5 is joined. Therefore, positioning recesses A3 are formed at a plurality of locations on the surface A1 of one plate material A, and positioning protrusions B2 are formed at a plurality of corresponding locations on the surface B1 of the other plate material B. Then, by joining the surfaces A1 and B1 of both plate materials A and B, both plate materials A and B can be joined without causing misalignment.
既に理解されるように、一方の板材Ａの表面に位置決め用の凹部Ａ３を形成する。他方の板材Ｂの表面に位置決め用の凸部Ｂ２を形成する。そして、前記位置決め用の凹部Ａ３と位置決め用の凸部Ｂ２とを嵌合することによって、一方の板材Ａの表面と他方の板材Ｂの表面とを接合している。したがって、両方の板材Ａ，Ｂを接合した後には、前記位置決め用の凹部Ａ３、凸部Ｂ２が外側に表れることがなく、外観が向上するものである。 As already understood, a recess A3 for positioning is formed on the surface of one of the plate materials A. A convex portion B2 for positioning is formed on the surface of the other plate material B. Then, the surface of one plate material A and the surface of the other plate material B are joined by fitting the concave portion A3 for positioning and the convex portion B2 for positioning. Therefore, after joining both the plate materials A and B, the positioning recess A3 and the convex portion B2 do not appear on the outside, and the appearance is improved.
図２は、本発明の第２実施形態を示すもので、前記実施形態における構成要素と同一機能を奏する構成要素には同一符号を付することとして、重複した説明は省略する。 FIG. 2 shows a second embodiment of the present invention, in which components having the same functions as the components in the embodiment are designated by the same reference numerals, and duplicate description will be omitted.
この第２の実施形態においては、前記位置決め凹部Ａ３の外周縁に環状の突出部Ａ６を形成したものである。この突出部Ａ６は、位置決め凹部Ａ３を形成する際に、位置決め凹部Ａ３の部分の肉の逃げ部として形成されるものである。したがって、位置決め凹部Ａ３における位置決め面Ａ２及び底面Ａ４の精度向上を図ることができるものである。また、板材Ａにおける表面Ａ１の平坦度の向上を図ることができる。上記構成においては、一方の板材Ａの表面Ａ１と他方の板材Ｂの表面Ｂ１とを接合したときに、前記突出部Ａ６は、図２に示すように、他方の板材Ｂにおける環状の溝Ｂ４内に入り込むことになる。 In this second embodiment, an annular protrusion A6 is formed on the outer peripheral edge of the positioning recess A3. The protruding portion A6 is formed as a meat relief portion of the portion of the positioning recess A3 when the positioning recess A3 is formed. Therefore, it is possible to improve the accuracy of the positioning surface A2 and the bottom surface A4 in the positioning recess A3. Further, the flatness of the surface A1 of the plate material A can be improved. In the above configuration, when the surface A1 of one plate material A and the surface B1 of the other plate material B are joined, the protruding portion A6 is formed in the annular groove B4 in the other plate material B as shown in FIG. It will get in.
換言すれば、一方の板材Ａにおける位置決め面Ａ２と、他方の板材Ｂにおける接合面Ｂ５との接触面がより大きくなる。したがって、一方の板材Ａの表面Ａ１と他方の板材Ｂの表面Ｂ１とを接合した際に、両方の板材Ａ，Ｂの接合がより安定的に行われ得るものである。 In other words, the contact surface between the positioning surface A2 on one plate material A and the joint surface B5 on the other plate material B becomes larger. Therefore, when the surface A1 of one plate material A and the surface B1 of the other plate material B are joined, both the plate materials A and B can be joined more stably.
