Description

本発明は、自在軸継手用ブーツの小径部に、小径バンドを仮取付けする小径バンド仮取付け装置に関する。   The present invention relates to a small-diameter band temporary attachment device for temporarily attaching a small-diameter band to a small-diameter portion of a universal shaft boot.

図９は自在軸継手の断面図であり、軸１０１の端部にジョイント部１０２を介してカップ部１０３が取付けられ、このカップ部１０３から軸部１０４が延ばされたものを自在軸継手１００と呼ぶ。軸１０１に対して軸部１０４を傾斜させることができるため、車両のドライブ軸に好んで使用される。自在軸継手のうち、軸１０１の回転速度と軸部１０４の回転速度が完全同一であるものを等速ジョイントと呼ぶ。すなわち、自在軸継手は等速ジョイント等の総称である。   FIG. 9 is a cross-sectional view of the universal shaft joint. A cup portion 103 is attached to an end portion of the shaft 101 via a joint portion 102, and the shaft portion 104 is extended from the cup portion 103. Call it. Since the shaft portion 104 can be inclined with respect to the shaft 101, it is preferably used for a drive shaft of a vehicle. Among the universal shaft joints, a joint in which the rotation speed of the shaft 101 and the rotation speed of the shaft portion 104 are completely the same is called a constant velocity joint. That is, the universal shaft joint is a general term for constant velocity joints and the like.

ジョイント部１０２に異物が入らぬように、軸１０１とカップ部１０３とに、ブーツ１０５が渡される。ブーツ１０５は、小径部１０６と、この小径部１０６より大径の大径部１０７と、大径部１０７と小径部１０６とを結ぶ円錐部１０８とからなる。円錐部１０８は、可撓性を付与するために蛇腹（じゃばら）構造を呈する。   The boot 105 is passed to the shaft 101 and the cup portion 103 so that foreign matter does not enter the joint portion 102. The boot 105 includes a small diameter portion 106, a large diameter portion 107 having a larger diameter than the small diameter portion 106, and a conical portion 108 that connects the large diameter portion 107 and the small diameter portion 106. The conical part 108 has a bellows structure to provide flexibility.

ブーツ１０５が軸１０１やカップ部１０３から外れないようにする必要がある。そこで、小径部１０６を小径バンド１１１で縮径して軸部１０１に強く結束し、大径部１０７を大径バンド１１２で縮径してカップ部１０３に強く結束する構造が採用される。   It is necessary to prevent the boot 105 from being detached from the shaft 101 or the cup portion 103. Therefore, a structure is adopted in which the small diameter portion 106 is reduced in diameter by the small diameter band 111 and is strongly bound to the shaft portion 101, and the large diameter portion 107 is reduced in diameter by the large diameter band 112 and is strongly bound to the cup portion 103.

従来から実施されてきた、小径バンド１１１の取付け手順は次の通りである。
ブーツ１０５単体にて、小径部１０６に小径バンド１１１を軽く嵌める（仮取付け工程）。この仮取付け工程は人手で行われてきた。
次に、小径部１０６を軸１０１に取付け、小径バンド１１１を強くかしめる（本取付け工程）。この本取付け工程はツールを用いた人手、又は機械で行なわれてきた。 The procedure for attaching the small-diameter band 111 that has been conventionally performed is as follows.
The small-diameter band 111 is lightly fitted to the small-diameter portion 106 with a single boot 105 (temporary attachment process). This temporary attachment process has been performed manually.
Next, the small-diameter portion 106 is attached to the shaft 101, and the small-diameter band 111 is caulked strongly (main attachment process). This main attachment process has been carried out manually using a tool or by a machine.

人手作業は生産性向上の点から機械化が望まれる。そこで、仮取付け工程や本取付け工程を自動化することができる技術が開発され実用に供されるようになってきた（例えば、特許文献１（図８）参照。）。   Manual work is desired to be mechanized from the viewpoint of improving productivity. Therefore, a technique capable of automating the temporary attachment process and the main attachment process has been developed and put into practical use (for example, see Patent Document 1 (FIG. 8)).

特許文献１を次図に基づいて説明する。
図１０は従来の技術の基本原理を説明する図であり、（ａ）において、小径部１０６又は大径部１０７に、ロボットハンドなどによりブーツバンド１１３を嵌める。このブーツバンド１１３は内径が、対象物の外径より十分に大きいため、簡単に嵌る。 Patent document 1 is demonstrated based on the following figure.
FIG. 10 is a diagram for explaining the basic principle of the prior art. In FIG. 10A, a boot band 113 is fitted to the small diameter portion 106 or the large diameter portion 107 by a robot hand or the like. Since this boot band 113 has an inner diameter sufficiently larger than the outer diameter of the object, it fits easily.

（ｂ）が仮取付け工程終了姿であり、小径部１０６又は大径部１０７とブーツバンド１１３との間に、大きな隙間１１４、１１４が存在する。そして、折り曲げ片１１５が外方へ延びている。
（ｃ）において、折り曲げ片１１５をロボットハンド等で引っ張り、約１８０°折り曲げる（本取付け工程）。結果、ブーツバンド１１３が縮径され、軸１０１又はカップ部１０３に強く結束される。 (B) is the appearance of the temporary attachment step, and there are large gaps 114, 114 between the small diameter portion 106 or the large diameter portion 107 and the boot band 113. Then, the bent piece 115 extends outward.
In (c), the bent piece 115 is pulled with a robot hand or the like and bent by about 180 ° (main attachment step). As a result, the boot band 113 is reduced in diameter and is strongly bound to the shaft 101 or the cup portion 103.

折り曲げ片１１５を設けたので、（ｂ）での大きな隙間１１４、１１４をゼロにすることができる。
しかし、回転体に折り曲げ片１１５が残ることは好ましくない。本取付け工程後に、折り曲げ片１１５を除去するには、折り曲げ片切除工程が必要となり、工程数が増す。 Since the bent piece 115 is provided, the large gaps 114 and 114 in (b) can be made zero.
However, it is not preferable that the bent piece 115 remains on the rotating body. In order to remove the bent piece 115 after the main attachment step, a bent piece excision step is required, which increases the number of steps.

一方、内径が、小径部１０６又は大径部１０７の外径とほぼ同じであるブーツバンドが注目される。縮径代が少なくて済むから折り曲げ片を設ける必要がなく、本取付工程が簡単になる、などの理由による。   On the other hand, attention is paid to a boot band whose inner diameter is substantially the same as the outer diameter of the small diameter portion 106 or the large diameter portion 107. This is because there is no need to provide a bent piece since the diameter reduction allowance is small, and this attachment process is simplified.

ただし、このようなブーツバンドでは、小径部１０６又は大径部１０７の外径との間に隙間が殆どないため、仮取付け工程を人手で行わざるを得ない。
しかし、生産性向上が求められる中、タイトなブーツバンドであっても仮取付け工程を自動化することが望まれる。 However, in such a boot band, since there is almost no gap between the outer diameter of the small diameter portion 106 or the large diameter portion 107, the temporary attachment process must be performed manually.
However, as productivity improvement is demanded, it is desired to automate the temporary attachment process even for a tight boot band.

And da 17, and a control unit 18 which controls collectively the components.

本発明の小径バンド仮取付け装置２０の構造を、図２〜図４に基づいて説明する。
図２に示すように、小径バンド仮取付け装置２０は、移動部材１６の下部から水平に張り出されるバンド押し下げ部材２１と、このバンド押し下げ部材２１上方位置にて移動部材１６に昇降可能に取付けら昇降部材２２と、この昇降部材２２を昇降するために昇降部材２２と移動部材１６とに渡されるサブ昇降シリンダ（図１、符号２３）と、昇降部材２２に水平ピン２４で揺動自在に止められ下方へ延びるバンド把持片２５と、このバンド把持片２５をバンドの拡径側へ揺動させるために昇降部材２２の中心に下向きに配置した第１ドライバー２６と、この第１ドライバー２６を昇降させる第１シリンダ２７と、バンド把持片２５をバンドの縮径側へ揺動させるために昇降部材２２とバンド把持片２５に渡した第１圧縮ばね２８と、昇降部材２２に水平ピン２９で揺動自在に止められ下方へ延びるブーツ把持片３１と、このブーツ把持片３１をブーツの拡径側へ揺動させるために昇降部材２２の中心に下向きに配置した第２ドライバー３２と、この第２ドライバー３２を昇降させる第２シリンダ３３と、ブーツ把持片３１をブーツの縮径側へ揺動させるために昇降部材２２とブーツ把持片３１に渡した第２圧縮ばね３４とを備える。 The structure of the small band temporary attachment device 20 of the present invention will be described with reference to FIGS.
As shown in FIG. 2, the small-band temporary mounting device 20 is attached to the moving member 16 so as to be movable up and down at a position above the band pressing member 21 and a band pressing member 21 that projects horizontally from the lower part of the moving member 16. The elevating member 22, the sub elevating cylinder (FIG. 1, 23) passed to the elevating member 22 and the moving member 16 to elevate the elevating member 22, and the elevating member 22 are swingably stopped by a horizontal pin 24. A band gripping piece 25 that extends downward, a first driver 26 that is disposed downward in the center of the lifting member 22 to swing the band gripping piece 25 toward the diameter-expanded side of the band, and lifts and lowers the first driver 26. A first cylinder 27 to be moved, a first compression spring 28 passed over the lifting member 22 and the band gripping piece 25 for swinging the band gripping piece 25 toward the reduced diameter side of the band, and a lifting part A boot gripping piece 31 that is supported by a horizontal pin 29 so as to be swingable and extends downward, and a second that is disposed downward in the center of the elevating member 22 so as to swing the boot gripping piece 31 toward the diameter expansion side of the boot. A driver 32, a second cylinder 33 for raising and lowering the second driver 32, and a second compression spring 34 passed to the elevating member 22 and the boot gripping piece 31 for swinging the boot gripping piece 31 toward the reduced diameter side of the boot With.

この例では、第１ドライバー２６と第１シリンダ２７とでバンド把持片揺動機構３５を構成した。第１ドライバー２６を下げると先端の先尖り部３６が、バンド把持片２５側の突起部３７を押すため、バンド把持片２５は図面時計方向に揺動する。第１ドライバー２６を上げると、第１圧縮ばね２８の付勢作用により、バンド把持片２５は図面反時計方向に揺動する。   In this example, the first driver 26 and the first cylinder 27 constitute the band gripping piece swing mechanism 35. When the first screwdriver 26 is lowered, the pointed portion 36 at the tip pushes the projection 37 on the band gripping piece 25 side, so that the band gripping piece 25 swings clockwise in the drawing. When the first driver 26 is raised, the band gripping piece 25 swings counterclockwise by the biasing action of the first compression spring 28.

同様に、第２ドライバー３２と第２シリンダ３３とでブーツ把持片揺動機構３８を構成した。第２ドライバー３２を下げると先端のテーパー部３９が、ブーツ把持片３１側のローラー４１を押すため、ブーツ把持片３１は図面反時計方向に揺動する。第２ドライバー３２を上げると、第２圧縮ばね３４の付勢作用により、ブーツ把持片３１は図面時計方向に揺動する。   Similarly, the second grip 32 and the second cylinder 33 constitute a boot gripping piece swing mechanism 38. When the second driver 32 is lowered, the tapered portion 39 at the tip pushes the roller 41 on the boot gripping piece 31 side, so that the boot gripping piece 31 swings counterclockwise in the drawing. When the second driver 32 is raised, the boot gripping piece 31 swings clockwise in the drawing due to the biasing action of the second compression spring 34.

バンド押し下げ部材２１には、図３に示すように、中央穴４２と、この中央穴４２から放射状に延びる長孔４３と、この長穴４３より幅広で中央穴４２から放射状に延びる長孔４４とが設けられている。狭い幅の長孔４３にバンド把持片２５が移動自在に収納され、広い幅の長孔４４にブーツ把持片３１が移動自在に収納されている。
中央穴４２の径は、小径バンドの径より小さいため、Ｖ字部４５で小径バンドを押すことができる。 As shown in FIG. 3, the band push-down member 21 includes a central hole 42, a long hole 43 that extends radially from the central hole 42, and a long hole 44 that is wider than the long hole 43 and extends radially from the central hole 42. Is provided. The band gripping piece 25 is movably accommodated in the narrow hole 43 and the boot gripping piece 31 is movably accommodated in the wide hole 44 having a wide width.
Since the diameter of the central hole 42 is smaller than the diameter of the small-diameter band, the small-diameter band can be pushed by the V-shaped portion 45.

小径バンド仮取付け装置（図２、符号２０）はさらに、図４（ａ）に示すように、軸（中心軸）が鉛直になるようにし且つブーツ４６の小径部４７が上になり、ブーツ４６の大径部４８が下になり、円錐部４９がハ字状になる姿勢で、ブーツ４６を支えるブーツ載せ台５１と、図４（ｂ）に示すように、ブーツ載せ台５１を貫通して鉛直方向に昇降し、小径部４７と円錐部４９との境界部５２を下から支える小径部支持部材５３と、この小径部支持部材５３を貫通して鉛直方向に昇降し、小径部４７に嵌ってブーツ４６の水平方向の位置を決めるブーツ位置決め部材５４とを備える。   As shown in FIG. 4 (a), the small-diameter band temporary attachment device (FIG. 2, reference numeral 20) is arranged so that the shaft (center axis) is vertical and the small-diameter portion 47 of the boot 46 is on top. The large-diameter portion 48 is at the bottom and the conical portion 49 is in the shape of a letter C. The boot platform 51 that supports the boot 46 and the boot platform 51 as shown in FIG. A small-diameter support member 53 that supports the boundary 52 between the small-diameter portion 47 and the conical portion 49 from below, and a small-diameter support member 53 that moves vertically through the small-diameter portion support member 53 and fits into the small-diameter portion 47. And a boot positioning member 54 that determines the position of the boot 46 in the horizontal direction.

図５（ａ）に示すように、小径バンド５６は、１個のコ字状の耳部５７を有する。（ｂ）に示すように、耳部５７を工具５８でΩ状に塑性変形させると、内径Ｄｂは小さくなる。   As shown in FIG. 5A, the small-diameter band 56 has one U-shaped ear portion 57. As shown in (b), when the ear portion 57 is plastically deformed into an Ω shape by the tool 58, the inner diameter Db becomes smaller.

（ａ）が仮取付け工程時の小径バンド５６の形態を示し、内径Ｄａは、ブーツの小径部の外径に近似する。仮取付け工程中は、内径Ｄａは変化しない。
本取付け工程は、（ａ）で始まり（ｂ）で終了する。すなわち、本取付け工程では、内径をＤａからＤｂへ減少させることで、小径部を軸に強く締結する。Ｄｂ＝Ｄａ−２・Δｄとなる。
本発明は仮取付けに係る装置を提供するため、（ａ）に示す小径バンド５６のみを対象とする。 (A) shows the form of the small diameter band 56 at the time of a temporary attachment process, and the internal diameter Da approximates the outer diameter of the small diameter part of a boot. During the temporary attachment process, the inner diameter Da does not change.
This attachment process starts with (a) and ends with (b). That is, in this attachment process, the small diameter portion is strongly fastened to the shaft by reducing the inner diameter from Da to Db. Db = Da−2 · Δd.
Since the present invention provides an apparatus for temporary attachment, only the small-diameter band 56 shown in FIG.

以上の構成からなる小径バンド仮取付け装置の作用を次に説明する。
図６（ａ）に示すように、ブーツ載せ台５１上のブーツ４６を、ブーツ位置決め部材５４で位置決めする。同時並行的にバンド把持片２５（図では１個が見えるが、１２０°ピッチで３個配置されている。）で小径バンド５６を把持しつつ、小径バンド仮置き台１２からブーツ位置決め部材５４の真上に臨ませる。そして、移動部材１６を下げる。 Next, the operation of the small-diameter band temporary attachment device configured as described above will be described.
As shown in FIG. 6A, the boot 46 on the boot platform 51 is positioned by the boot positioning member 54. At the same time, while holding the small-diameter band 56 with the band gripping pieces 25 (one is visible in the figure, but three are arranged at a pitch of 120 °), the boot positioning member 54 can be Let it face directly above. Then, the moving member 16 is lowered.

すると、（ｂ）に示すように、小径バンド５６が小径部４７の直上に至る。同時に、ブーツ把持片３１がブーツ位置決め部材５４を押し下げつつ小径部４７内に進入する。   Then, as shown in (b), the small-diameter band 56 reaches directly above the small-diameter portion 47. At the same time, the boot gripping piece 31 enters the small diameter portion 47 while pushing down the boot positioning member 54.

図７（ａ）はブーツ把持片３１のみを示した図であり、小径部４７の内周面４７ａに、ブーツ把持片３１が当たる。また、ブーツ４６の境界部５２が小径部支持部材５３で支えられている。
（ｂ）はバンド把持片２５のみを示した図であり、小径バンド５６が小径部４７の真上にある。（ａ）、（ｂ）は同タイミングでの形態を示す。 FIG. 7A shows only the boot gripping piece 31, and the boot gripping piece 31 hits the inner peripheral surface 47 a of the small diameter portion 47. Further, the boundary portion 52 of the boot 46 is supported by the small diameter portion supporting member 53.
(B) is a view showing only the band gripping piece 25, and the small-diameter band 56 is directly above the small-diameter portion 47. (A), (b) shows the form at the same timing.

この状態から、ブーツ把持片３１及びバンド把持片２５は静止させたままで、バンド押し下げ部材２１を下げる。すると、（ｃ）に示すように、小径部４７に小径バンド５６が嵌められる。   From this state, the band push-down member 21 is lowered while the boot grip piece 31 and the band grip piece 25 remain stationary. Then, as shown in (c), the small-diameter band 56 is fitted into the small-diameter portion 47.

小径部４７は、弾性に富むゴム又は軟質樹脂で造られる。いわゆる腰が弱いため、仮に、支えることなく小径部４７にほぼ同径の小径バンド５６を嵌めようとすると、小径部４７が偏平化したり座屈（押し力で波打つこと）する。結果、小径バンド５６を小径部４７に嵌めることができない。   The small diameter portion 47 is made of elastic rubber or soft resin. Since the so-called waist is weak, if the small-diameter band 56 having substantially the same diameter is fit into the small-diameter portion 47 without supporting it, the small-diameter portion 47 becomes flattened or buckles (wavy by pressing force). As a result, the small diameter band 56 cannot be fitted into the small diameter portion 47.

その点、本発明では、図７（ａ）〜（ｃ）に示すように、押し力に耐えるようにブーツ４６の境界部５２を小径部支持部材５３で支え、且つ偏平化しないように小径部４７の内周面４７ａをブーツ把持片３１で支えながら、小径バンド５６を嵌めたので、仮取付け作業が、円滑に行える。 In that respect, in the present invention, as shown in FIGS. 7A to 7C, the boundary portion 52 of the boot 46 is supported by the small-diameter portion supporting member 53 so as to withstand the pushing force, and the small-diameter portion is not flattened. Since the small-diameter band 56 is fitted while the inner peripheral surface 47a of 47 is supported by the boot gripping piece 31, the temporary attachment work can be performed smoothly.

図８に示すように、仮取付け作業（仮取付け工程）が終わったブーツ４６は、ブーツ把持片３１で把持しつつ、持ち上げ、水平移動して大径バンド仮取付け装置（図１、符号６０）へ移動する。
以上に説明した作用は、一括して、制御部（図１、符号１８）で実施させるため、タイトな小径バンド５６であっても仮取付けが自動化できた。 As shown in FIG. 8, the boot 46 that has been temporarily attached (temporary attachment step) is lifted and horizontally moved while being gripped by the boot gripping piece 31 (FIG. 1, reference numeral 60). Move to.
Since the operations described above are collectively performed by the control unit (FIG. 1, reference numeral 18), temporary mounting can be automated even with the tight small-diameter band 56.

尚、本発明は、車両用の自在軸継手に付属するブーツに好適であるが、一般機械用の自在軸継手に付属するブーツに適用することは差し支えない。   The present invention is suitable for a boot attached to a universal shaft joint for a vehicle, but may be applied to a boot attached to a universal shaft joint for a general machine.
