上記従来の技術では、ブラケットをバンドに溶接固定しているので、シリンダチューブや配管が繰り返し振動することによって溶接部が破損する可能性がある。   In the above conventional technique, since the bracket is welded and fixed to the band, the welded portion may be damaged by repeated vibration of the cylinder tube and piping.

本発明は、このような技術的課題に鑑みてなされたものであり、溶接部を設けることなく配管をシリンダチューブに固定可能な配管固定具を提供することを目的とする。   This invention is made | formed in view of such a technical subject, and it aims at providing the piping fixing tool which can fix piping to a cylinder tube, without providing a welding part.

本発明は、シリンダチューブ内に作動流体を給排する配管をシリンダチューブに固定する流体圧シリンダの配管固定具であって、シリンダチューブの外周に沿って湾曲した湾曲部を有し、湾曲部の両端同士を固定することでシリンダチューブを挟持する２つの半割状のバンドを備え、一方のバンドは、湾曲部の一部がシリンダチューブから径方向外側に向けて離間した、配管が取り付けられる取付部を有し、取付部を有するバンドは、プレス加工によって一体成型される、ことを特徴とする。 The present invention is a fluid pressure cylinder piping fixture for fixing a piping for supplying and discharging a working fluid in a cylinder tube to the cylinder tube, and has a curved portion curved along the outer periphery of the cylinder tube. It is equipped with two halved bands that clamp the cylinder tube by fixing both ends, and one band is a part where the curved part is separated from the cylinder tube toward the outside in the radial direction. part have a, a band having an attachment portion are integrally molded by press working, characterized in that.

本発明によれば、バンドの一方がシリンダチューブから径方向外側に離間した取付部を有し、この取付部に配管が取り付けられるので、溶接部を設けることなく配管をシリンダチューブに固定することができる。よって、配管固定具の強度を向上させることができる。   According to the present invention, since one of the bands has a mounting portion that is spaced radially outward from the cylinder tube, and the pipe is attached to this mounting portion, the piping can be fixed to the cylinder tube without providing a welding portion. it can. Therefore, the strength of the pipe fixture can be improved.

本発明の実施形態に係る流体圧シリンダの配管固定具を示す斜視図である。It is a perspective view which shows the piping fixture of the fluid pressure cylinder which concerns on embodiment of this invention. 図１の配管固定具をシリンダチューブの軸方向に沿って見た図である。It is the figure which looked at the piping fixing tool of FIG. 1 along the axial direction of a cylinder tube. 本発明の他の実施形態に係る流体圧シリンダの配管固定具をシリンダチューブの軸方向に沿って見た図である。It is the figure which looked at the piping fixture of the fluid pressure cylinder which concerns on other embodiment of this invention along the axial direction of a cylinder tube.

図面を参照して、本発明の実施形態について説明する。   Embodiments of the present invention will be described with reference to the drawings.

図１は、本実施形態における流体圧シリンダ１の配管固定具１００を示す斜視図である。図２は、図１の配管固定具１００をシリンダチューブ２の軸方向に沿って見た図である。   FIG. 1 is a perspective view showing a pipe fixture 100 of a fluid pressure cylinder 1 in the present embodiment. FIG. 2 is a view of the piping fixture 100 of FIG. 1 as viewed along the axial direction of the cylinder tube 2.

流体圧シリンダ１は、例えば作業機械のアームやブーム等を駆動する油圧シリンダであり、流体圧源から供給される作動流体圧の給排に応じて伸縮作動する。なお、流体圧シリンダ１の作動流体として、オイルの代わりに水溶性代替液等を用いてもよい。   The fluid pressure cylinder 1 is, for example, a hydraulic cylinder that drives an arm, a boom, or the like of a work machine, and expands and contracts according to supply / discharge of the working fluid pressure supplied from a fluid pressure source. As the working fluid of the fluid pressure cylinder 1, a water-soluble alternative liquid or the like may be used instead of oil.

流体圧シリンダ１は、シリンダチューブ２と、シリンダチューブ２内を摺動するピストン（不図示）と、ピストンに連結されてシリンダチューブ２の一端から延出されるピストンロッド（不図示）と、を備える。ピストンによって区画されたシリンダチューブ２内の２つの圧力室（不図示）のうち、少なくとも一方に作動流体が給排されると、圧力室間の圧力差に応じてピストンが摺動する。これにより、ピストンロッドとシリンダチューブ２とが軸方向に相対移動して作業機械の駆動部材が駆動される。   The fluid pressure cylinder 1 includes a cylinder tube 2, a piston (not shown) that slides in the cylinder tube 2, and a piston rod (not shown) that is connected to the piston and extends from one end of the cylinder tube 2. . When the working fluid is supplied to or discharged from at least one of the two pressure chambers (not shown) in the cylinder tube 2 defined by the piston, the piston slides according to the pressure difference between the pressure chambers. As a result, the piston rod and the cylinder tube 2 are relatively moved in the axial direction to drive the drive member of the work machine.

流体圧シリンダ１はさらに、圧力室に作動流体を給排する配管３を備える。配管３は、作業機械への搭載性を向上させるため、シリンダチューブ２の軸方向に沿って配設される。   The fluid pressure cylinder 1 further includes a pipe 3 for supplying and discharging the working fluid to and from the pressure chamber. The pipe 3 is disposed along the axial direction of the cylinder tube 2 in order to improve the mountability to the work machine.

次に、配管３をシリンダチューブ２に固定する配管固定具１００について説明する。   Next, the pipe fixture 100 that fixes the pipe 3 to the cylinder tube 2 will be described.

配管固定具１００は、シリンダチューブ２を挟持するように配置される２つの半割状の第１バンド１０及び第２バンド２０を備える。   The pipe fixing device 100 includes two halved first bands 10 and second bands 20 arranged so as to sandwich the cylinder tube 2.

第１バンド１０は、シリンダチューブ２の外周に沿って湾曲した略半円形状の湾曲部１１と、湾曲部１１の両端からシリンダチューブ２の径方向外側へ向けて延設された延設部１２と、を有する。   The first band 10 includes a substantially semicircular curved portion 11 that is curved along the outer periphery of the cylinder tube 2, and an extended portion 12 that extends from both ends of the curved portion 11 toward the radially outer side of the cylinder tube 2. And having.

第２バンド２０は、シリンダチューブ２の外周に沿って湾曲した略半円形状の湾曲部２１と、湾曲部２１の両端からシリンダチューブ２の径方向外側へ向けて延設された延設部２２と、湾曲部２１の一部がシリンダチューブ２から径方向外側に離間するように形成された取付部２３と、を有する。取付部２３は、湾曲部２１の途中であって湾曲部２１の両端から略等しい距離の位置に設けられ、シリンダチューブ２の径方向に垂直な平面状に形成される。取付部２３はさらに、配管３を固定するためのボルト穴２４を有する。なお、取付部２３は、必ずしも湾曲部２１の両端から略等しい距離の位置に設けられる必要はなく、どちらか一端に偏った位置に設けられてもよい。   The second band 20 includes a substantially semicircular curved portion 21 that is curved along the outer periphery of the cylinder tube 2, and an extended portion 22 that extends from both ends of the curved portion 21 toward the radially outer side of the cylinder tube 2. And a mounting portion 23 formed so that a part of the curved portion 21 is spaced radially outward from the cylinder tube 2. The attachment portion 23 is provided in the middle of the bending portion 21 at a position that is substantially equal to the distance from both ends of the bending portion 21, and is formed in a planar shape that is perpendicular to the radial direction of the cylinder tube 2. The attachment portion 23 further has a bolt hole 24 for fixing the pipe 3. In addition, the attachment part 23 does not necessarily need to be provided in the position of the substantially equal distance from the both ends of the bending part 21, and may be provided in the position biased to either one end.

第１バンド１０と第２バンド２０とは、シリンダチューブ２を径方向両側から挟み込むように装着され、互いの延設部１２、２２同士を対向配置させる。各延設部１２、２２には、それぞれボルト穴１３、１４が設けられており、ボルト穴１３、１４にボルト１５を挿通することで第１バンド１０と第２バンド２０とはボルト締めされる。第１バンド１０及び第２バンド２０の寸法は、ボルト締めされた場合に第１バンド１０及び第２バンド２０がシリンダチューブ２の外周に密着するように予め設定される。   The 1st band 10 and the 2nd band 20 are mounted | worn so that the cylinder tube 2 may be pinched | interposed from radial direction both sides, and mutual extension parts 12 and 22 may be opposingly arranged. Bolt holes 13 and 14 are respectively provided in the extended portions 12 and 22, and the first band 10 and the second band 20 are bolted by inserting the bolts 15 into the bolt holes 13 and 14. . The dimensions of the first band 10 and the second band 20 are set in advance so that the first band 10 and the second band 20 are in close contact with the outer periphery of the cylinder tube 2 when bolted.

配管固定具１００はさらに、取付部２３に固定されることで配管３を取付部２３との間で挟持するパイプホルダ３０を備える。パイプホルダ３０は、本体部３１と、本体部３１から延設されて配管３の外周面の一部を覆って配管３を保持するように形成される保持部３２と、本体部３１に設けられるボルト穴３３と、を有する。   The pipe fixing tool 100 further includes a pipe holder 30 that is fixed to the attachment part 23 to clamp the pipe 3 with the attachment part 23. The pipe holder 30 is provided in the main body 31, a holding section 32 that extends from the main body 31 and covers the outer peripheral surface of the pipe 3 so as to hold the pipe 3, and the main body 31. And a bolt hole 33.

パイプホルダ３０が配管３を保持した状態でパイプホルダ３０のボルト穴３３と取付部２３のボルト穴２４とが位置決めされ、パイプホルダ３０と取付部２３とがボルト締めされる。これにより、配管３はパイプホルダ３０の保持部３２と取付部２３との間で挟持される。パイプホルダ３０の締め付け高さ（締め付け深さとも言う）は、配管３が取付部２３に適度に押圧される程度に設定される。   With the pipe holder 30 holding the pipe 3, the bolt hole 33 of the pipe holder 30 and the bolt hole 24 of the mounting portion 23 are positioned, and the pipe holder 30 and the mounting portion 23 are bolted. Thereby, the piping 3 is clamped between the holding part 32 and the attachment part 23 of the pipe holder 30. The tightening height (also referred to as tightening depth) of the pipe holder 30 is set to such an extent that the pipe 3 is appropriately pressed against the mounting portion 23.

ここで、パイプホルダ３０を第２バンド２０に取り付けるためには、第２バンド２０の内周側にボルト３４及びボルト３４を締め付けるナット３５が突出する分だけスペースを設ける必要がある。   Here, in order to attach the pipe holder 30 to the second band 20, it is necessary to provide a space on the inner peripheral side of the second band 20 so that the bolt 35 and the nut 35 for tightening the bolt 34 protrude.

この点、本実施形態では、取付部２３を湾曲部２１より径方向外側に離間させているので、取付部２３の径方向内側面とシリンダチューブ２の外周面との間に当該スペースが確保される。第１バンド１０及び第２バンド２０は、共に湾曲部１１、２１と延設部１２、２２とを有し、これをプレス加工によって成型している。よって、第２バンド２０だけ取付部２３に対応する凹部を有する型にプレスすることで、第１バンド１０及び第２バンド２０ともにプレス加工によって一体成型することができる。   In this respect, in the present embodiment, the mounting portion 23 is spaced radially outward from the curved portion 21, so that the space is secured between the radially inner side surface of the mounting portion 23 and the outer peripheral surface of the cylinder tube 2. The Both the first band 10 and the second band 20 have curved portions 11 and 21 and extended portions 12 and 22, which are formed by press working. Therefore, by pressing only the second band 20 into a mold having a recess corresponding to the mounting portion 23, both the first band 10 and the second band 20 can be integrally formed by pressing.

またここで、第２バンド２０の形状を第１バンド１０と同一の形状としてプレス加工によって第１バンド１０及び第２バンド２０を成型した後、第２バンド２０の外周面にパイプホルダ３０を取り付けるためのブラケットを溶接することも考えられる。   Further, here, after forming the first band 10 and the second band 20 by press working with the second band 20 having the same shape as the first band 10, the pipe holder 30 is attached to the outer peripheral surface of the second band 20. It is also conceivable to weld a bracket for this purpose.

しかし、流体圧シリンダ１が搭載される作業機械では、運転中は常に振動がシリンダチューブ２及び配管３に加わるので、繰り返し振動を受けることで、溶接部が破損する可能性がある。また、第１バンド１０及び第２バンド２０の延設部１２、２２同士をボルト締めする際に第２バンド２０が内径側に締め付けられて変形し、ブラケットの複数の溶接部間の距離が変化して溶接部が破損する可能性がある。   However, in a work machine in which the fluid pressure cylinder 1 is mounted, vibration is always applied to the cylinder tube 2 and the pipe 3 during operation. Therefore, there is a possibility that the welded portion may be damaged due to repeated vibration. Further, when the extended portions 12 and 22 of the first band 10 and the second band 20 are bolted together, the second band 20 is tightened and deformed to the inner diameter side, and the distance between the plurality of welded portions of the bracket changes. As a result, the weld may be damaged.

さらに、ブラケットをシリンダチューブ２の外周に溶接固定するためには、予め溶接位置にブラケットを固定する溶接用治具が必要である。しかし、シリンダチューブ２の外周に装着されるバンドには流体圧シリンダ１の種類に応じて様々な形状があるので、流体圧シリンダ１ごとに溶接用治具を用意する必要があり、製造時の作業工数及びコストが増加する。   Furthermore, in order to fix the bracket to the outer periphery of the cylinder tube 2 by welding, a welding jig for fixing the bracket to the welding position in advance is required. However, since the band attached to the outer periphery of the cylinder tube 2 has various shapes depending on the type of the fluid pressure cylinder 1, it is necessary to prepare a welding jig for each fluid pressure cylinder 1. Work man-hours and costs increase.

そこで、本実施形態では、シリンダチューブ２の外周に装着される第２バンド２０をプレス加工する際に、取付部２３を共に成型し、この取付部２３にパイプホルダ３０を固定している。これにより、溶接部が不要となる上、取付部２３は第２バンド２０と一体的に成型されているので、配管固定具１００の強度を向上させることができる。   Therefore, in the present embodiment, when the second band 20 attached to the outer periphery of the cylinder tube 2 is pressed, the attachment portion 23 is molded together, and the pipe holder 30 is fixed to the attachment portion 23. Thereby, since a welding part becomes unnecessary, since the attaching part 23 is shape | molded integrally with the 2nd band 20, the intensity | strength of the piping fixing tool 100 can be improved.

さらに、溶接作業が不要となるので、流体圧シリンダ１ごとに用意していた溶接用治具が不要となり、製造時の作業工数及びコストを抑制することができる。   Furthermore, since welding work is not required, a welding jig prepared for each fluid pressure cylinder 1 is not required, and work man-hours and costs during manufacturing can be suppressed.

以上の実施形態によれば、以下に示す効果を奏する。   According to the above embodiment, there exist the effects shown below.

シリンダチューブ２の外周に装着される第１バンド１０及び第２バンド２０のうち、第２バンド２０にはシリンダチューブ２から径方向外側に離間した取付部２３が設けられ、配管３が取付部２３に取り付けられるので、溶接部を設けることなく配管３をシリンダチューブ２に固定することができる。よって、配管固定具１００の強度を向上させることができるとともに、溶接用治具が不要となって製造時の作業工数及びコストを抑制することができる。   Of the first band 10 and the second band 20 mounted on the outer periphery of the cylinder tube 2, the second band 20 is provided with an attachment portion 23 spaced radially outward from the cylinder tube 2, and the pipe 3 is attached to the attachment portion 23. Therefore, the pipe 3 can be fixed to the cylinder tube 2 without providing a welded portion. Therefore, the strength of the pipe fixture 100 can be improved, and a welding jig is not required, so that work man-hours and costs during manufacturing can be suppressed.

さらに、配管３は、パイプホルダ３０に保持された状態で取付部２３に固定されることで、パイプホルダ３０と取付部２３との間で挟持されるので、簡素な構造で配管３の脱落を防止することができる。   Furthermore, the piping 3 is clamped between the pipe holder 30 and the mounting portion 23 by being fixed to the mounting portion 23 while being held by the pipe holder 30, so that the piping 3 can be removed with a simple structure. Can be prevented.

さらに、取付部２３はシリンダチューブ２の径方向に垂直な平面状に形成されるので、取付部２３は湾曲部２１から径方向に平行に隆起した形状となる。よって、第２バンド２０を型に押圧してプレス加工する際に、プレスの押圧方向と取付部２３の隆起方向とが一致するので、加工性を向上させることができる。   Furthermore, since the attachment portion 23 is formed in a planar shape perpendicular to the radial direction of the cylinder tube 2, the attachment portion 23 has a shape protruding in parallel with the radial direction from the curved portion 21. Therefore, when pressing the second band 20 against the mold and pressing, the pressing direction of the press and the protruding direction of the mounting portion 23 coincide with each other, so that the workability can be improved.

さらに、第１バンド１０及び第２バンド２０は、それぞれプレス加工によって一体成型されるので、第１バンド１０と第２バンド２０とを固定するための延設部１２、２２と、パイプホルダ３０及び配管３を取り付けるための取付部２３と、を同一の工程で成型することができる。よって、製造時の作業工数を低減することができる。   Furthermore, since the first band 10 and the second band 20 are each integrally formed by pressing, the extending portions 12 and 22 for fixing the first band 10 and the second band 20, the pipe holder 30, The attachment portion 23 for attaching the pipe 3 can be molded in the same process. Therefore, the work man-hour at the time of manufacture can be reduced.

以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一つを示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。   The embodiment of the present invention has been described above. However, the above embodiment is merely one example of application of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment. Absent.

例えば、上記実施形態では、パイプホルダ３０を取付部２３に固定することで配管３を取付部２３とパイプホルダ３０との間に挟持しているが、図３に示すように、パイプホルダ４０と取付部２３との間にプレート５０を介することで、配管３をシリンダチューブ２から離れた位置に保持させることも可能である。   For example, in the above embodiment, the pipe holder 30 is fixed to the attachment portion 23 to hold the pipe 3 between the attachment portion 23 and the pipe holder 30, but as shown in FIG. It is also possible to hold the piping 3 at a position away from the cylinder tube 2 by interposing the plate 50 between the mounting portion 23.

この場合、パイプホルダ４０は、配管３を径方向両側から挟持する一対のホルダ部４１と、両ホルダ４１を貫通するボルト穴４２と、から構成される。パイプホルダ４０をボルト締めすることで、配管３が両ホルダ部４１によって挟持される。   In this case, the pipe holder 40 includes a pair of holder portions 41 that sandwich the pipe 3 from both sides in the radial direction, and a bolt hole 42 that penetrates both the holders 41. The pipe 3 is clamped by both the holder parts 41 by bolting the pipe holder 40.

プレート５０は、例えば途中で屈曲した板状部材であり、両端にそれぞれボルト穴５１を有する。プレート５０は、取付部２３にボルト締めされるとともにパイプホルダ４０にボルト締めされる。パイプホルダ４０がプレート５０の一端にボルト締めされると、ボルト４５の締め付け力に応じて配管３が挟持される。一対のホルダ部４１の内径寸法及びボルト４５の締め付け力は、配管３の挟持力が所望の値となるように予め設定される。   The plate 50 is, for example, a plate-like member bent halfway, and has bolt holes 51 at both ends. The plate 50 is bolted to the attachment portion 23 and bolted to the pipe holder 40. When the pipe holder 40 is bolted to one end of the plate 50, the pipe 3 is clamped according to the tightening force of the bolt 45. The inner diameter dimension of the pair of holder portions 41 and the tightening force of the bolt 45 are set in advance so that the clamping force of the pipe 3 becomes a desired value.

The pipe holder 30 and the attachment portion 23 may be fixed by screwing a thread on the inner periphery of the hole and screwing the bolt 34 into the bolt hole. The same applies to the fixation between the plate 50 and the mounting portion 23.

さらに、上記実施形態では、第１バンド１０及び第２バンド２０をプレス加工によって一体成型する場合を例示したが、これに代えて、アルミなどの押し出し材による一体成型や樹脂材による一体成型であってもよい。すなわち、第１バンド１０及び第２バンド２０はあらゆる素材によって成型することができる。   Furthermore, in the above-described embodiment, the case where the first band 10 and the second band 20 are integrally formed by press working is exemplified. However, instead of this, integral molding using an extrusion material such as aluminum or integral molding using a resin material is used. May be. That is, the first band 10 and the second band 20 can be molded from any material.

さらに、上記実施形態では、取付部２３をシリンダチューブ２の径方向に垂直な平面状に形成したが、これに限らず、傾斜していてもよい。   Furthermore, in the said embodiment, although the attaching part 23 was formed in planar shape perpendicular | vertical to the radial direction of the cylinder tube 2, it may not be restricted to this but may incline.

さらに、上記実施形態では、第１バンド１０及び第２バンド２０の双方がプレス加工によって一体成型される場合を例示したが、これに代えて、取付部２３を有する第２バンド２０のみプレス加工によって一体成型し、取付部２３を有しない第１バンド１０はプレス加工以外の加工法、例えば切削等によって形成してもよい。   Furthermore, in the said embodiment, although the case where both the 1st band 10 and the 2nd band 20 were integrally molded by press work was illustrated, it replaced with this and only the 2nd band 20 which has the attaching part 23 is press-processed. The first band 10 which is integrally molded and does not have the attachment portion 23 may be formed by a processing method other than press processing, such as cutting.

また、第１バンド１０のみプレス加工によって一体成型し、取付部２３を有する第２バンド２０はプレス加工以外の加工法、例えば切削等によって形成してもよい。さらに、第１バンド１０及び第２バンド２０の双方をプレス加工以外の加工法、例えば切削等によって形成してもよい。つまり、溶接部を設けることなく取付部２３を有するバンドを加工できる方法であれば任意の加工法を用いることができる。   Alternatively, only the first band 10 may be integrally formed by press working, and the second band 20 having the attachment portion 23 may be formed by a processing method other than press working, such as cutting. Furthermore, both the first band 10 and the second band 20 may be formed by a processing method other than press processing, such as cutting. That is, any processing method can be used as long as it can process the band having the attachment portion 23 without providing a welded portion.
