Description

本発明は、予め穿設された板材のかしめ孔にかしめ部材を固着させるかしめ装置に関するものである。   The present invention relates to a caulking device for fixing a caulking member to a caulking hole of a plate material drilled in advance.

板材にかしめ部材を取り付ける方法として、かしめ加工によってかしめ部材と板材とを固着させる方法がある。このとき用いられるかしめ部材には、上端側に略円筒形の拡径部が設けられている。また、板材には略すり鉢状のかしめ孔が形成されている。そして、かしめ部材の拡径部を板材のかしめ孔の両開口のうち小径となる一方の開口側から挿通させ、その状態のまま大径となる他方の開口側から拡径部を押圧する。   As a method of attaching the caulking member to the plate material, there is a method of fixing the caulking member and the plate material by caulking. The caulking member used at this time is provided with a substantially cylindrical enlarged diameter portion on the upper end side. The plate material is formed with a substantially mortar-shaped caulking hole. And the enlarged diameter part of a caulking member is inserted from one opening side which becomes a small diameter among both openings of the caulking hole of a plate material, and the enlarged diameter part is pressed from the other opening side which becomes a large diameter in that state.

従来、このようなかしめ加工を行なうためのかしめ装置として、下記特許文献1に開示されるようなものがあった。このかしめ装置のパンチが設けられている上部側の構造は、逆L字状の基枠が設けられ、その上端部に水平方向に延設された上延部が設けられ、この上延部の先端にシリンダーが設けられ、シリンダーの先端に軸が上下動可能に上延部の下方に向かって設けられているものであった。軸の下端部には、パンチが取り付けられ、軸とともに上下動する。   Conventionally, as a caulking device for performing such caulking, there has been one disclosed in Patent Document 1 below. The structure on the upper side where the punch of this caulking device is provided is provided with an inverted L-shaped base frame, and an upper extension portion extending in the horizontal direction is provided at the upper end portion thereof. A cylinder was provided at the tip, and a shaft was provided at the tip of the cylinder toward the bottom of the upper extension so as to be movable up and down. A punch is attached to the lower end of the shaft and moves up and down together with the shaft.

上述したようなかしめ装置の一般的なパンチの構成としては、図4に示すように、軸100の下端部に、略円錐形のパンチ101が尖端を下方に向けて設けられている。このパンチ101の周面は、比較的緩やかな傾斜角に形成されている。   As shown in FIG. 4, the general punch structure of the caulking apparatus as described above is provided with a substantially conical punch 101 at the lower end portion of the shaft 100 with the pointed end facing downward. The peripheral surface of the punch 101 is formed at a relatively gentle inclination angle.

このようなパンチ101によるかしめ加工は、図4(a)に示すように、板材103のかしめ孔104にかしめ部材102の拡径部105を挿通させて、パンチ101の中心軸B(B1 )とかしめ部材102の中心軸B(B2 )とが一致するように位置合わせを行なう。そして、図4(b)に示すように、位置合わせを終えたかしめ部材102に向けてパンチ101を下降させ拡径部105を略放射方向に拡径させ、かしめ部材102と板材103とを固着させる。ここで、パンチ101が下降に要する時間は、0.1秒以下という僅かな時間である。 As shown in FIG. 4A, the caulking process by the punch 101 is performed by inserting the enlarged diameter portion 105 of the caulking member 102 into the caulking hole 104 of the plate material 103, and the center axis B (B 1 ) of the punch 101. Positioning is performed so that the center axis B (B 2 ) of the caulking member 102 coincides. Then, as shown in FIG. 4B, the punch 101 is lowered toward the caulking member 102 after the alignment is completed, and the enlarged diameter portion 105 is enlarged in a substantially radial direction, and the caulking member 102 and the plate material 103 are fixed. Let Here, the time required for the punch 101 to descend is a short time of 0.1 second or less.

なお、かしめ部材106には、例えばプリント基板などを取り付けるため内部に雌ネジ孔106が形成されている。また、このかしめ部材102は、板材103に支柱として立設固着される。
特開平9−10862号公報
The caulking member 106 has a female screw hole 106 formed therein for attaching a printed circuit board, for example. Further, the caulking member 102 is erected and fixed to the plate member 103 as a support column.
Japanese Patent Laid-Open No. 9-10862

しかしながら、上述した従来のかしめ装置では、図4(b)に示すように、パンチ101の形状が、緩やかな傾斜角の周面を有する略円錐形であるため、下降してくるパンチ101は、その周面で上方から押さえつけるように拡径部105と当接する。これにより、パンチ101がかしめ部材102を押圧する際、まず最初に下向きの応力が生じ、拡径部105は略放射方向に拡径されるよりも先に略垂下方向に潰れてしまう。これにより、拡径部105が略放射方向に対して充分に拡径されず、かしめ部材102と板材103との固着強度を弱めてしまうという問題があった。   However, in the above-described conventional caulking apparatus, as shown in FIG. 4B, since the shape of the punch 101 is a substantially conical shape having a circumferential surface with a moderate inclination angle, It abuts on the enlarged diameter portion 105 so as to be pressed from above on its peripheral surface. As a result, when the punch 101 presses the caulking member 102, a downward stress is first generated, and the diameter-enlarged portion 105 is crushed in a substantially drooping direction before being expanded in a substantially radial direction. As a result, there is a problem in that the diameter-enlarged portion 105 is not sufficiently expanded in the radial direction and the fixing strength between the caulking member 102 and the plate material 103 is weakened.

また、かしめ部材102の内部に雌ネジ孔106が形成されている場合、下向きの応力による略垂下方向への潰れが雌ネジ孔106まで到達してしまい、雌ネジ孔106を潰してしまうことがあった。   Further, when the female screw hole 106 is formed inside the caulking member 102, the crushing in the substantially drooping direction due to the downward stress reaches the female screw hole 106, and the female screw hole 106 may be crushed. there were.

図5に示すように、パンチ101とかしめ部材102との互いの中心軸B(B1 ,B2 )とがずれた状態でかしめ作業を行なうと、パンチ101の拡径部105に与える押圧力に片寄りが生じる。したがって、図5(b)に示すように、拡径部105の拡径に変形が発生し、かしめ保持力が低下してしまうという問題があった。このために、パンチ101とかしめ部材102との互いの中心軸B(B1 ,B2 )との位置合わせを行なう必要がある。その際、板材103のかしめ孔104にかしめ部材102を挿通させた状態のままで、このかしめ部材102を作業者の手作業によって微調整していた。そのため、この位置合わせの作業が煩雑となり、また、位置合わせに時間がかかっていた。これにより、かしめ加工の作業性及びかしめ製品の量産性を低下させてしまうという問題があった。 As shown in FIG. 5, when the caulking operation is performed in a state where the center axes B (B 1 , B 2 ) of the punch 101 and the caulking member 102 are shifted from each other, the pressing force applied to the enlarged diameter portion 105 of the punch 101 Is offset. Therefore, as shown in FIG. 5B, there is a problem that deformation occurs in the diameter expansion of the diameter expansion portion 105 and the caulking holding force is reduced. For this purpose, it is necessary to align the punch 101 and the caulking member 102 with the center axes B (B 1 , B 2 ) of each other. At this time, the caulking member 102 was finely adjusted by the operator's manual operation while the caulking member 102 was inserted into the caulking hole 104 of the plate member 103. For this reason, this alignment work becomes complicated, and the alignment takes time. Thereby, there existed a problem that the workability | operativity of a caulking process and the mass productivity of a caulking product will be reduced.

そこで本発明は、上記問題点を解消するために、パンチでかしめ部材をかしめることによる拡径部の下方への潰れを防ぎ、且つ拡径部を均一に押圧することで品質のよいかしめ加工を可能にするとともに、かしめ装置とかしめ部材との位置合わせを容易にして、かしめ加工の作業性を向上させ、さらに、かしめ製品の量産性を向上させるかしめ装置を提供することを目的としている。   Therefore, in order to solve the above-described problems, the present invention prevents the expanded portion from being crushed by caulking the caulking member with a punch, and performs high-quality caulking processing by pressing the expanded portion uniformly. It is an object of the present invention to provide a caulking device that makes it possible to facilitate the positioning of the caulking device and the caulking member, improve the workability of the caulking process, and further improve the mass productivity of the caulking product.

次に、上記の課題を解決するための手段を、実施の形態に対応する図面を参照して説明する。
本発明の請求項1記載のかしめ装置は、略垂下方向に延びて下端面に凹部4が形成されている軸3と、該軸3の下端部に連設され中央に貫通孔6が形成されている端板5と、を備えた軸部2と、
前記軸部2の下方に前記端板5と遊嵌状態で配置され該端板5の外周縁から所定間隔の間隙Cをあけて該端板5を囲むように周壁9が立設されている基盤8と、該基盤8の下方に配設され略円柱形の基端部14から略円錘状に形成されている先端部15にかけて成形面11が形成されているパンチ10と、を備えた押圧部7と、
を具備するかしめ装置1であって、
前記成形面11が、前記基端部14側に緩傾斜に形成されている押圧面12を有するとともに、前記先端部15側に急傾斜に形成されている摺動面13を有し、前記押圧面12から前記摺動面13にかけて湾曲凹面状に形成されていることを特徴とする。
Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
The caulking device according to claim 1 of the present invention includes a shaft 3 extending substantially in a hanging direction and having a recess 4 formed at a lower end surface thereof, and a through-hole 6 formed in the center at the lower end portion of the shaft 3. An end plate 5, and a shaft portion 2 comprising:
A peripheral wall 9 is erected below the shaft portion 2 so as to be loosely fitted to the end plate 5 so as to surround the end plate 5 with a predetermined gap C from the outer peripheral edge of the end plate 5. A base 8 and a punch 10 having a molding surface 11 formed from a substantially cylindrical base end 14 disposed under the base 8 to a tip 15 formed in a substantially conical shape. A pressing portion 7;
A caulking device 1 comprising:
The molding surface 11 has a pressing surface 12 formed on the proximal end portion 14 side with a gentle slope, and a sliding surface 13 formed on the distal end portion 15 side with a steep slope, and the pressing surface 12 A curved concave surface is formed from the surface 12 to the sliding surface 13.

請求項2記載のかしめ装置は、請求項1記載のかしめ装置において、
前記端板5と前記基盤8との間に介設され該基盤8を中心軸Aと直交する面上で滑動させる滑動手段16と、
前記端板5に向かって前記基盤8を付勢させる付勢手段17と、を備えたことを特徴とする。
The caulking device according to claim 2 is the caulking device according to claim 1,
Sliding means 16 interposed between the end plate 5 and the base 8 for sliding the base 8 on a plane orthogonal to the central axis A;
And an urging means 17 for urging the base 8 toward the end plate 5.

このような構成によれば、下降してくるパンチ10が拡径部31と当接する最初の段階において、急傾斜の摺動面13が拡径部31の内周縁34と当接し、そのままパンチ10が下降するにつれて徐々に拡径部31を略放射方向へと押圧する。これにより、パンチ10が拡径部31に当接する最初の段階で、拡径部31は下向きの応力をほとんど受けないため、拡径部31の下方への潰れを防止することが可能となる。また、パンチ10が下降を終える最後の段階において、拡径部31は、緩傾斜の押圧面12によって略垂下方向へと押圧される。これにより、かしめ部材30と板材40とを強力に固着させることが可能となる。したがって、品質のよいかしめ加工が可能となる。   According to such a configuration, at the first stage where the descending punch 10 abuts on the enlarged diameter portion 31, the steeply inclined sliding surface 13 abuts on the inner peripheral edge 34 of the enlarged diameter portion 31, and the punch 10 is left as it is. As the diameter descends, the diameter-expanded portion 31 is gradually pressed in a substantially radial direction. As a result, at the initial stage when the punch 10 abuts on the enlarged diameter portion 31, the enlarged diameter portion 31 is hardly subjected to downward stress, and therefore it is possible to prevent the expanded diameter portion 31 from being crushed downward. Further, at the final stage when the punch 10 finishes descending, the diameter-expanded portion 31 is pressed in a substantially hanging direction by the gently inclined pressing surface 12. As a result, the caulking member 30 and the plate member 40 can be firmly fixed. Therefore, it is possible to perform caulking with high quality.

また、かしめ部材30の内部に雌ネジ孔32が形成されている場合、パンチ10が拡径部31と当接する最初の段階において、このパンチ10は拡径部31に下向きの応力をほとんど与えないため、拡径部31が下方へ潰れることによる雌ネジ孔32の潰れを防止することができる。これにより、品質のよいかしめ加工が可能となるという上記と同様の効果が得られる。   Further, when the female screw hole 32 is formed in the caulking member 30, the punch 10 hardly applies a downward stress to the enlarged diameter portion 31 in the first stage where the punch 10 contacts the enlarged diameter portion 31. Therefore, it is possible to prevent the female screw hole 32 from being crushed due to the diameter-expanded portion 31 being crushed downward. Thereby, the same effect as the above that caulking processing with good quality becomes possible is obtained.

さらに、軸部2と押圧部7との間に滑動手段16が設けられ、且つ軸部2の端板5と押圧部7の基盤8との間に間隙Cが形成されていることによって、押圧部7をその中心軸Aと直交する面上における略放射方向に滑動させることが可能となる。これにより、かしめ装置1とかしめ部材30との位置合わせの際、押圧部12を中心軸Aと直交する面上における何れかの方向へ移動し、互いの位置合わせが完了する。このため、位置合わせの作業にかかる時間を短縮できる。したがって、かしめ加工の作業性を向上させることが可能となり、さらに、かしめ製品の量産性を向上させることが可能となる。   Further, the sliding means 16 is provided between the shaft portion 2 and the pressing portion 7, and the gap C is formed between the end plate 5 of the shaft portion 2 and the base 8 of the pressing portion 7. The portion 7 can be slid in a substantially radial direction on a plane orthogonal to the central axis A. As a result, when the caulking device 1 and the caulking member 30 are aligned, the pressing portion 12 is moved in any direction on the plane orthogonal to the central axis A, and the mutual alignment is completed. For this reason, the time required for the alignment work can be shortened. Therefore, it is possible to improve the workability of the caulking process, and it is possible to improve the mass productivity of the caulking product.

本発明によるかしめ装置によれば、下降してくるパンチが拡径部に当接する最初の段階で、拡径部はパンチから下向きの応力をほとんど受けないため、拡径部の下方への潰れを防止することが可能となる。また、パンチが下降を終える最後の段階において、拡径部は、押圧面によって略垂下方向へと押圧され、かしめ部材と板材とを強力に固着させることが可能となる。したがって、品質のよいかしめ加工が可能となる。   According to the caulking device of the present invention, at the first stage when the descending punch comes into contact with the enlarged diameter portion, the enlarged diameter portion receives almost no downward stress from the punch, so that the expanded diameter portion is not crushed downward. It becomes possible to prevent. Further, at the final stage when the punch finishes descending, the diameter-enlarged portion is pressed in a substantially hanging direction by the pressing surface, and the caulking member and the plate material can be strongly fixed. Therefore, it is possible to perform caulking with high quality.

また、かしめ部材の内部に雌ネジ孔が形成されている場合、パンチが拡径部と当接する最初の段階において、このパンチは拡径部に下向きの応力をほとんど与えないため、拡径部が下方へ潰れることによる雌ネジ孔の潰れを防止することができる。これにより、品質のよいかしめ加工が可能となるという上記と同様の効果が得られる。   In addition, when a female screw hole is formed inside the caulking member, the punch does not apply a downward stress to the enlarged diameter portion at the first stage where the punch comes into contact with the enlarged diameter portion. It is possible to prevent the female screw hole from being crushed by being crushed downward. Thereby, the same effect as the above that caulking processing with good quality becomes possible is obtained.

さらに、軸部と押圧部との間に滑動手段が設けられ、且つ軸部の端板と押圧部の基盤との間に間隙が形成されていることによって、押圧部を略放射方向に滑動させることが可能となる。これにより、かしめ装置とかしめ部材との位置合わせの際、押圧部をその中心軸と直交する面上における何れかの方向へ移動し、押圧部7をずらすという作業を行なうことなく位置合わせが完了し、位置合わせの作業にかかる時間を短縮できる。したがって、かしめ加工の作業性を向上させることが可能となり、さらに、かしめ製品の量産性を向上させることが可能となる。   Further, sliding means is provided between the shaft portion and the pressing portion, and a gap is formed between the end plate of the shaft portion and the base of the pressing portion, whereby the pressing portion is slid in a substantially radial direction. It becomes possible. Thereby, when aligning the caulking device and the caulking member, the alignment is completed without moving the pressing portion in any direction on the surface orthogonal to the central axis and shifting the pressing portion 7. In addition, the time required for the alignment work can be shortened. Therefore, it is possible to improve the workability of the caulking process, and it is possible to improve the mass productivity of the caulking product.

以下、本発明の実施の形態を図面を参照して具体的に説明する。
図1は本発明によるかしめ装置の一実施の形態を示す正面断面図、図2は同平面図、図3(a),(b)は本発明によるかしめ装置を構成するパンチの動作を示す正面断面図である。

The shaft portion 2 includes a shaft and an end plate.
As shown in FIG. 1, the shaft 3 is provided so as to extend substantially in the hanging direction. The shaft 3 has a substantially circular recess 4 formed at the lower end surface.
As shown in FIGS. 1 and 2, the end plate 5 is formed on a substantially circular plate, and is provided on the lower end surface of the shaft 3 in a substantially flange shape. A through hole 6 is formed in the end plate 5 at the center. The inner diameter of the through hole 6 is slightly smaller than the inner diameter of the recess 4.

押圧部7は、基盤8とパンチ10とで構成されている。
基盤8は、図1及び図2に示すように、略円板形の底部18の外周縁から略円筒形の周壁9が上向きに立設されている。ここで、周壁9の内周縁は、上述した端板5の外周縁より大径に形成されている。この基盤8は、端板5と遊嵌状態となっており、端板5の外周縁から周壁9の外周縁までには所定間隔の間隙Cが形成されている。
パンチ10は、図1に示すように、基盤8の裏面側に設けられている。パンチ10は、上方に略円柱形の基端部14を有し、下方に略円錘状に形成されている先端部15を有している。基端部14から先端部15にかけては成形面11が形成されている。成形面11には、基端部14側に押圧面12が形成され、先端部15側に摺動面13が形成されている。押圧面12は、水平方向に対して緩やかな傾斜面に形成されている。また、摺動面13は、水平方向に対して急な傾斜面に形成されている。押圧面12から摺動面13にかけては湾曲凹面状に形成されている。基端部14の下部から先端部15にかけては連続した曲面となっている。
The pressing portion 7 includes a base 8 and a punch 10.
As shown in FIGS. 1 and 2, the base 8 has a substantially cylindrical peripheral wall 9 erected upward from an outer peripheral edge of a substantially disc-shaped bottom 18. Here, the inner peripheral edge of the peripheral wall 9 is formed larger in diameter than the outer peripheral edge of the end plate 5 described above. The base 8 is loosely fitted with the end plate 5, and a gap C with a predetermined interval is formed from the outer peripheral edge of the end plate 5 to the outer peripheral edge of the peripheral wall 9.
As shown in FIG. 1, the punch 10 is provided on the back side of the base 8. The punch 10 has a substantially cylindrical base end portion 14 on the upper side and a distal end portion 15 formed in a substantially conical shape on the lower side. A molding surface 11 is formed from the base end portion 14 to the tip end portion 15. On the molding surface 11, a pressing surface 12 is formed on the proximal end portion 14 side, and a sliding surface 13 is formed on the distal end portion 15 side. The pressing surface 12 is formed in a gentle inclined surface with respect to the horizontal direction. Moreover, the sliding surface 13 is formed in the steeply inclined surface with respect to the horizontal direction. A curved concave surface is formed from the pressing surface 12 to the sliding surface 13. A curved surface is continuous from the lower part of the base end part 14 to the front end part 15.

なお、本実施の形態では、端板5は略円板上に形成されているが、この形状に限るものではない。例えば、端板5の形状が略三角板状に形成されてもよい。ただし、その際、遊嵌状態なっている基盤8の内形の形状は、端板5の形状と略同等(例えば、略三角凹状)且つやや大形に形成されていなければならない。   In the present embodiment, the end plate 5 is formed on a substantially circular plate, but is not limited to this shape. For example, the shape of the end plate 5 may be formed in a substantially triangular plate shape. However, in that case, the shape of the inner shape of the base plate 8 that is loosely fitted should be substantially the same as the shape of the end plate 5 (for example, a substantially triangular concave shape) and slightly larger.

上述したように、遊嵌状態となっている軸部2の端板5と押圧部7の基盤8との間には、滑動手段16が設けられている。本実施の形態では、図1及び図2に示すように、滑動手段として、ボールベアリング16が使用されている。   As described above, the sliding means 16 is provided between the end plate 5 of the shaft portion 2 in the loosely fitted state and the base 8 of the pressing portion 7. In the present embodiment, as shown in FIGS. 1 and 2, a ball bearing 16 is used as the sliding means.

また、軸部2と押圧部7とは、付勢手段17によって連結されるとともに、押圧部7を軸部2側へと付勢させている。本実施の形態では、図1及び図2に示すように、引っ張りバネ17を付勢手段としている。この引っ張りバネ17は、一端が軸3の凹部4の内面に固着され、他端が基盤8の内面に固着され、常時付勢力が付与されている。   Further, the shaft portion 2 and the pressing portion 7 are connected by the biasing means 17 and bias the pressing portion 7 toward the shaft portion 2 side. In the present embodiment, as shown in FIGS. 1 and 2, the tension spring 17 is used as a biasing means. One end of the tension spring 17 is fixed to the inner surface of the recess 4 of the shaft 3, and the other end is fixed to the inner surface of the base 8, and a biasing force is always applied.

次に、上記したかしめ装置1によって固着されるかしめ部材30と板材40について説明する。   Next, the caulking member 30 and the plate member 40 fixed by the above-described caulking device 1 will be described.

かしめ部材30は、支柱部33と拡径部31とで略構成されている。支柱部33は、本実施の形態では、略六角ナット状に形成されている。支柱部33の内部には軸線方向に雌ネジ孔32が形成されている。この支柱部33の両端面のうち、いずれか一方に略円筒形の拡径部31が、この支柱部33と軸A(A2 )を同じくして立設されている。 The caulking member 30 is substantially composed of a support column 33 and an enlarged diameter portion 31. The support | pillar part 33 is formed in the substantially hexagon nut shape in this Embodiment. A female screw hole 32 is formed in the support column 33 in the axial direction. A substantially cylindrical diameter-increased portion 31 is erected on either one of both end surfaces of the column portion 33 so as to have the same axis A (A 2 ) as the column portion 33.

板材40には、複数のかしめ孔41が穿設されている。かしめ孔41は、略すり鉢状に形成されている。かしめ孔41の両開口のうち、小径となる開口は、上述したかしめ部材30の拡径部31が挿通可能に形成されている。   A plurality of caulking holes 41 are formed in the plate member 40. The caulking hole 41 is formed in a substantially mortar shape. Of the two openings of the caulking hole 41, the opening having a small diameter is formed so that the above-described enlarged diameter portion 31 of the caulking member 30 can be inserted.

以下、本実施の形態のかしめ装置1によるかしめ加工の工程について説明する。   Hereinafter, the process of caulking by the caulking apparatus 1 of the present embodiment will be described.

まず、かしめ部材30の拡径部31を板材40のかしめ孔41に挿通させ、受台20上に配置する。このとき、拡径部31はかしめ孔41の小径となる開口側から挿通させる。
次に、かしめ部材30の拡径部31の内周縁34にかしめ装置1の摺動面13が当接するまでかしめ装置1を下降させる。この状態でかしめ装置1の中心軸となる押圧部7の中心軸A(A1 )とかしめ部材30の中心軸A(A2 )とが一致していないときは、かしめ装置1の押圧部7が略放射方向に移動可能なので、押圧部7は、その中心軸A(A1 )をかしめ部材30の中心軸A(A2 )に合わせるように移動する。また、このとき、押圧部7の摺動面13が急傾斜のため力の加わる方向が略水平となるので容易に押圧部7が移動することができる。
First, the enlarged diameter portion 31 of the caulking member 30 is inserted into the caulking hole 41 of the plate member 40 and is arranged on the cradle 20. At this time, the enlarged diameter portion 31 is inserted from the opening side where the caulking hole 41 has a small diameter.
Next, the caulking device 1 is lowered until the sliding surface 13 of the caulking device 1 contacts the inner peripheral edge 34 of the enlarged diameter portion 31 of the caulking member 30. In this state, when the central axis A (A 1 ) of the pressing portion 7 serving as the central axis of the caulking device 1 does not coincide with the central axis A (A 2 ) of the caulking member 30, the pressing portion 7 of the caulking device 1. Therefore, the pressing part 7 moves so that the central axis A (A 1 ) thereof is aligned with the central axis A (A 2 ) of the caulking member 30. At this time, since the sliding surface 13 of the pressing portion 7 is steeply inclined, the direction in which the force is applied becomes substantially horizontal, so that the pressing portion 7 can easily move.

ここで、かしめ装置1のパンチ10が、かしめ部材30の拡径部31をかしめていく過程について述べる。
図3(a)に示すように、パンチ10は、その成形面11のうち、まず、急傾斜の摺動面13が拡径部31の内周縁34と当接して、かしめ装置1の押圧部7の中心軸A(A1 )とかしめ部材の中心軸A(A2 )とが一致した状態にある。そして、そのままパンチ10が下降するにつれて、拡径部31は、摺動面13から押圧面12に到るまでの曲面に沿って徐々に外向きとなる略放射方向へ拡径される。最後に、図3(b)に示すように、充分に拡径された拡径部31は、押圧面12によって略垂下方向へと押圧され、かしめ孔の内周面に押圧される。かしめ部材30は、拡径部31と支柱部33の端面とでかしめ孔41の内周面を押さえつけることで、板材40と固着される。
Here, a process in which the punch 10 of the caulking device 1 caulks the enlarged diameter portion 31 of the caulking member 30 will be described.
As shown in FIG. 3A, the punch 10 has a pressing surface of the caulking device 1 in which the steeply inclined sliding surface 13 first comes into contact with the inner peripheral edge 34 of the enlarged diameter portion 31. 7 central axis a and (a 1) central axis of the caulking member a (a 2) is in the matched state of the. Then, as the punch 10 descends as it is, the diameter-expanded portion 31 is gradually expanded in a radial direction that gradually becomes outward along the curved surface from the sliding surface 13 to the pressing surface 12. Finally, as shown in FIG. 3B, the diameter-expanded portion 31 that has been sufficiently expanded is pressed by the pressing surface 12 in a substantially drooping direction and is pressed against the inner peripheral surface of the caulking hole. The caulking member 30 is fixed to the plate member 40 by pressing the inner peripheral surface of the caulking hole 41 with the enlarged diameter portion 31 and the end surface of the column portion 33.

この実施の形態によれば、下降してくるパンチ10が拡径部31と当接する最初の段階において、急傾斜の摺動面13が拡径部31の内周縁34と当接し、そのままパンチ10が下降するにつれて徐々に拡径部31を略放射方向へと押圧する。これにより、パンチ10が拡径部31に当接する最初の段階で、拡径部31は、図3(a)に図示するベクトル方向、つまり、下向きの応力をほとんど受けないため、拡径部31の下方への潰れを防止することが可能となる。また、パンチ10が下降を終える最後の段階において、拡径部31は、緩傾斜の押圧面12によって、図3(b)に図示するベクトル方向、つまり、略垂下方向へと押圧される。これにより、かしめ部材30と板材40とを強力に固着させることが可能となる。したがって、品質のよいかしめ加工が可能となる。   According to this embodiment, at the first stage where the descending punch 10 abuts on the enlarged diameter portion 31, the steeply inclined sliding surface 13 abuts on the inner peripheral edge 34 of the enlarged diameter portion 31, and the punch 10 is left as it is. As the diameter descends, the diameter-expanded portion 31 is gradually pressed in a substantially radial direction. Thereby, at the initial stage where the punch 10 abuts on the enlarged diameter portion 31, the enlarged diameter portion 31 receives almost no downward stress in the vector direction shown in FIG. It is possible to prevent crushing downward. Further, at the final stage when the punch 10 finishes descending, the enlarged diameter portion 31 is pressed by the gently inclined pressing surface 12 in the vector direction shown in FIG. As a result, the caulking member 30 and the plate member 40 can be firmly fixed. Therefore, it is possible to perform caulking with high quality.

また、かしめ部材30の内部に雌ネジ孔32が形成されている場合、パンチ10が拡径部31と当接する最初の段階において、このパンチ10は拡径部31に下向きの応力をほとんど与えないため、拡径部31が下方へ潰れることによる雌ネジ孔32の潰れを防止することができる。これにより、品質のよいかしめ加工が可能となるという上記と同様の効果が得られる。   Further, when the female screw hole 32 is formed in the caulking member 30, the punch 10 hardly applies a downward stress to the enlarged diameter portion 31 in the first stage where the punch 10 contacts the enlarged diameter portion 31. Therefore, it is possible to prevent the female screw hole 32 from being crushed due to the diameter-expanded portion 31 being crushed downward. Thereby, the same effect as the above that caulking processing with good quality becomes possible is obtained.

さらに、軸部2と押圧部7との間にボールベアリング16が設けられ、且つ軸部2の端板5と押圧部7の基盤8との間に間隙Cが形成されていることによって、押圧部7を略水平面上(中心軸Aと直交する面上)における略放射方向に滑動させることが可能となる。これにより、かしめ装置1とかしめ部材30との位置合わせの際、押圧部12を略水平面上(中心軸Aと直交する面上)における何れかの方向し、互いの位置合わせが完了する。このため、位置合わせの作業にかかる時間を短縮できる。したがって、かしめ加工の作業性を向上させることが可能となり、さらに、かしめ製品の量産性を向上させることが可能となる。   Further, a ball bearing 16 is provided between the shaft portion 2 and the pressing portion 7, and a gap C is formed between the end plate 5 of the shaft portion 2 and the base 8 of the pressing portion 7. The part 7 can be slid in a substantially radial direction on a substantially horizontal plane (on a plane orthogonal to the central axis A). As a result, when the caulking device 1 and the caulking member 30 are aligned, the pressing portion 12 is oriented in any direction on a substantially horizontal plane (on a plane orthogonal to the central axis A), and the mutual alignment is completed. For this reason, the time required for the alignment work can be shortened. Therefore, it is possible to improve the workability of the caulking process, and it is possible to improve the mass productivity of the caulking product.
