Description

本発明は、シャーランナー又はナットランナーなどの締結装置の反力受けに関する。 The present invention relates to a reaction force receiver for a fastening device such as a shear runner or a nut runner.

ボルト等の締付けに用いられる締結装置には、反力受けを有するものがある。反力受けには、外周面から突出する突起部が設けられている。反力受けを利用してボルトの締付けを行う際、別のボルトに突起部を当てて反力受けが回転しない状態にすることで、締結装置からボルトに強いトルクを伝達することができる。しかし、締付け対象のボルトの近くに、反力受けの突起部を当てる物体がない状況もあり得る。 Some fastening devices used for tightening bolts and the like have a reaction force receiver. The reaction force receiver is provided with a protrusion that protrudes from the outer peripheral surface. When tightening a bolt using a reaction force receiver, strong torque can be transmitted from the fastening device to the bolt by placing the protrusion on another bolt so that the reaction force receiver does not rotate. However, there may be a situation where there is no object near the bolt to be tightened against which the protrusion of the reaction force receiver is applied.

特許文献１には、隣接ボルトとの距離に応じて反力受けの突起部長さを調節可能な反力受けが記載されている。ボルト間の距離が長い場合、反力受けと一体に構成された突起部に対し、別の突起部が固定された状態で、反力受けが使用される。 Patent Document 1 describes a reaction force receiver in which the length of a protruding portion of the reaction force receiver can be adjusted according to the distance from an adjacent bolt. When the distance between the bolts is long, the reaction force receiver is used with another protrusion fixed to the protrusion integrated with the reaction force receiver.

特許文献２には、ナットランナーの本体に装着される筒体と、その筒体の一端部の外周において突出させた爪片とからなる反力受けが記載されている。この反力受けの爪片には、複数の貫通孔が設けられている。この反力受けは、爪片の貫通孔にピンを挿通することで、ピンをフランジの外周面に当接させて反力を受けることができる。 Patent Document 2 describes a reaction force receiver that includes a cylindrical body that is attached to the main body of a nut runner, and a claw piece that protrudes from the outer periphery of one end of the cylindrical body. A plurality of through holes are provided in the claw piece of this reaction force receiver. This reaction force receiver can receive a reaction force by inserting a pin into the through hole of the claw piece and bringing the pin into contact with the outer peripheral surface of the flange.

ところで、特許文献１に記載の反力受けは、締付け対象のボルトが設けられた面、又はその面に平行な面のボルトを利用して、反力を受けることができるが、そのようなボルトがない場合には対応できない。また、特許文献２に記載の反力受けは、締付け対象のボルトの近くにピンを当てる面がない場合には対応できない。 By the way, the reaction force receiver described in Patent Document 1 can receive reaction force by using the bolt on the surface where the bolt to be tightened is provided or the surface parallel to that surface. We cannot respond if there is no one. Further, the reaction force receiver described in Patent Document 2 cannot be used when there is no surface on which the pin is applied near the bolt to be tightened.

本発明は、このような事情に鑑みてなされたものであり、様々な状況において反力を受けることが可能な反力受け用のアタッチメントを実現することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to realize a reaction force receiving attachment that can receive reaction forces in various situations.

上述の課題を解決するべく、第１の発明は、締結装置の反力受けの突起部に対し着脱自在に取り付け可能な、反力受け用のアタッチメントであって、ともに板状に形成されて互いに対面する第１主面部及び第２主面部と、第１主面部と第２主面部との間に設けられて当該アタッチメントの外周面を構成すると共に、外周面に入口が開口して突起部が嵌め込まれる篏合穴を、第１主面部と第２主面部との間に形成する中間部とを備え、当該アタッチメントでは、篏合穴に対する突起部の挿入方向における入口とは反対側に、厚さ方向に貫通する貫通孔が形成されている。 In order to solve the above-mentioned problems, a first invention is a reaction force receiving attachment that can be detachably attached to a protrusion of a reaction force receiving part of a fastening device, both of which are formed in a plate shape and are attached to each other. The first main surface portion and the second main surface portion facing each other are provided between the first main surface portion and the second main surface portion to constitute the outer circumferential surface of the attachment, and an inlet is opened on the outer circumferential surface and a protrusion is provided. The attachment includes an intermediate portion that forms a mating hole to be fitted between the first main surface portion and the second main surface portion, and the attachment has a thickness on the side opposite to the entrance in the insertion direction of the protrusion into the mating hole. A through hole is formed that penetrates in the horizontal direction.

第２の発明は、第１の発明において、篏合穴には、突起部のうち少なくとも先端から付け根近傍までの範囲を嵌め込み可能である。 In a second invention, in the first invention, at least a range from the tip to the vicinity of the base of the protrusion can be fitted into the fitting hole.

第３の発明は、第１又は第２の発明において、第１主面部及び第２主面部の各々は、中間部に比べて厚みが小さい。 In a third aspect of the invention, in the first or second aspect, each of the first main surface part and the second main surface part has a smaller thickness than the intermediate part.

第４の発明は、第１乃至第３の何れか１つの発明において、篏合穴について挿入方向に直交する方向を幅方向とした場合に、貫通孔の直径は、篏合穴の奥部分の幅よりも大きい。 A fourth aspect of the invention is that in any one of the first to third aspects, when the width direction of the mating hole is a direction perpendicular to the insertion direction, the diameter of the through hole is the diameter of the inner part of the mating hole. greater than the width.

本発明では、アタッチメントの篏合穴に反力受けの突起部を挿入することで、締付け対象のボルトから比較的離れたボルトにアタッチメントが届くようになる。そのため、このような状況でも、アタッチメントの外周面で反力を受けることができる。さらに、アタッチメントにおける厚さ方向の貫通孔に棒材（又はピンなど）を嵌め込むことで、締付け対象のボルトから比較的離れた面に棒材を当てることができる。そのため、このような状況でも、棒材で反力を受けることができる。本発明によれば、様々な状況において反力を受けることが可能な反力受け用のアタッチメントを実現することができる。 In the present invention, by inserting the protrusion of the reaction force receiver into the mating hole of the attachment, the attachment can reach a bolt that is relatively distant from the bolt to be tightened. Therefore, even in such a situation, the reaction force can be received on the outer circumferential surface of the attachment. Furthermore, by fitting the bar (or pin, etc.) into the through hole in the thickness direction of the attachment, the bar can be applied to a surface relatively distant from the bolt to be tightened. Therefore, even in such a situation, the bar can receive the reaction force. According to the present invention, it is possible to realize a reaction force receiving attachment that can receive reaction forces in various situations.

以下、図面を参照しながら、本発明の実施形態を詳細に説明する。なお、以下の実施形態は、本発明の一例であって、本発明、その適用物、あるいはその用途の範囲を制限することを意図するものではない。 Embodiments of the present invention will be described in detail below with reference to the drawings. Note that the following embodiments are examples of the present invention, and are not intended to limit the scope of the present invention, its applications, or its uses.

本実施形態は、シャーランナー又はナットランナーなどの締結装置１（図５参照）の反力受け５の突起部７に対し着脱自在に取り付け可能な、反力受け用のアタッチメント（以下、「アタッチメント」と言う。）１０である。アタッチメント１０は、突起部７が挿入される孔として、突起部７の形状に対応した形状の篏合穴２０が形成されている。アタッチメント１０は、例えば金属製である。以下では、篏合穴２０に対して突起部７が挿入される方向（挿入方向）を「長さ方向」、その長さ方向に直交する方向を「幅方向」と言う。 This embodiment is a reaction force receiving attachment (hereinafter referred to as an "attachment") that can be detachably attached to a protrusion 7 of a reaction force receiving 5 of a fastening device 1 (see FIG. 5) such as a shear runner or a nut runner. ) 10. In the attachment 10, a mating hole 20 having a shape corresponding to the shape of the protrusion 7 is formed as a hole into which the protrusion 7 is inserted. The attachment 10 is made of metal, for example. Hereinafter, the direction in which the protrusion 7 is inserted into the mating hole 20 (insertion direction) will be referred to as the "length direction", and the direction perpendicular to the length direction will be referred to as the "width direction".

ここで、反力受け５は、締結装置１の部品の１つであり、締結装置本体２に着脱自在である。反力受け５は、図１に示すように、円筒状の外筒部４と、外筒部４の外周面に一体化された突起部７とを備えている。突起部７は、外筒部４の外周面から径方向に突出している。突起部７は、平板状に形成され、付け根に近づくに従って幅が徐々に広くなる平面形状（図１では、略二等辺三角形状）を有する。なお、図面においてハッチング箇所は溶接部を表す。 Here, the reaction force receiver 5 is one of the components of the fastening device 1, and is detachable from the fastening device main body 2. As shown in FIG. 1, the reaction force receiver 5 includes a cylindrical outer cylinder part 4 and a protrusion part 7 integrated with the outer peripheral surface of the outer cylinder part 4. The protrusion 7 protrudes from the outer circumferential surface of the outer cylinder 4 in the radial direction. The protrusion 7 is formed into a flat plate shape, and has a planar shape (approximately isosceles triangular shape in FIG. 1) whose width gradually increases as it approaches the base. Note that hatched areas in the drawings represent welded areas.

アタッチメント１０は、図２に示すように、互いに対面する第１主面部１１及び第２主面部１２と、第１主面部１１と第２主面部１２との間に設けられて当該アタッチメント１０の外周面２１を構成する中間部１３とを備えている。第１主面部１１及び第２主面部１２は、第１主面部１１に固定用ネジ穴１５が設けられている以外は、同じものである。中間部１３は、第１主面部１１と第２主面部１２との間に、図３（ａ）及び図３（ｂ）に示すように、上述の篏合穴２０を形成する。篏合穴２０の入口２０ｅは、アタッチメント１０の外周面２１に開口している。 As shown in FIG. 2, the attachment 10 is provided between a first main surface portion 11 and a second main surface portion 12 facing each other, and between the first main surface portion 11 and the second main surface portion 12, and is provided on the outer periphery of the attachment 10. An intermediate portion 13 forming a surface 21 is provided. The first main surface section 11 and the second main surface section 12 are the same except that the first main surface section 11 is provided with a fixing screw hole 15. The intermediate portion 13 forms the above-mentioned fitting hole 20 between the first main surface portion 11 and the second main surface portion 12, as shown in FIGS. 3(a) and 3(b). The entrance 20e of the mating hole 20 opens to the outer circumferential surface 21 of the attachment 10.

第１主面部１１及び第２主面部１２の各々は、平板状に形成されている。各主面部１１，１２の平面形状は、図４（ａ）及び図４（ｂ）に示すように、略等脚台形であり、幅方向に比べて長さ方向の寸法が大きい。各主面部１１，１２は、例えばレーザー切断加工により平板を切断することにより形成されている。各主面部１１，１２は、中間部１３に比べて厚みが小さい。各主面部１１，１２の厚みは、例えば１０ｍｍ以下である。また、各主面部１１，１２の先端部には、円形の貫通孔１１ｈ，１２ｈが形成されている。第１主面部１１と第２主面部１２では、平面視における同じ位置に、同じ大きさの貫通孔１１ｈ，１２ｈが形成されている。 Each of the first main surface portion 11 and the second main surface portion 12 is formed into a flat plate shape. As shown in FIGS. 4(a) and 4(b), the planar shape of each main surface portion 11, 12 is approximately an isosceles trapezoid, and the dimension in the length direction is larger than that in the width direction. Each main surface portion 11, 12 is formed by cutting a flat plate using, for example, laser cutting processing. Each main surface portion 11, 12 has a smaller thickness than the intermediate portion 13. The thickness of each main surface portion 11, 12 is, for example, 10 mm or less. Furthermore, circular through holes 11h and 12h are formed at the tips of the main surface parts 11 and 12, respectively. In the first main surface section 11 and the second main surface section 12, through holes 11h and 12h of the same size are formed at the same position in plan view.

中間部１３は、図４（ｃ）に示すように、平面視において等脚台形の部材の下底から、突起部７に対応した形状の切れ込み１３ｎが形成された部材である。中間部１３は、例えばレーザー切断加工により平板を切断することにより形成されている。中間部１３における等脚台形は、各主面部１１，１２と同様に、幅方向に比べて長さ方向の寸法が大きい。中間部１３は、長さ方向の寸法が各主面部１１，１２と同じであり、幅方向の寸法が各主面部１１，１２よりも少し大きい。中間部１３の厚みは、突起部７の厚みと略等しい。 As shown in FIG. 4C, the intermediate portion 13 is a member having an isosceles trapezoidal shape in plan view, with a notch 13n having a shape corresponding to the protrusion 7 formed from the bottom of the member. The intermediate portion 13 is formed by cutting a flat plate using, for example, laser cutting. The isosceles trapezoid in the intermediate portion 13 has a larger dimension in the length direction than in the width direction, similarly to the main surface portions 11 and 12. The intermediate portion 13 has the same dimension in the length direction as the main surface portions 11 and 12, and has a slightly larger dimension in the width direction than the main surface portions 11 and 12. The thickness of the intermediate portion 13 is approximately equal to the thickness of the protrusion 7.

また、中間部１３の先端部には、円形の貫通孔１３ｈが形成されている。貫通孔１３ｈの大きさは、各貫通孔１１ｈ，１２ｈの大きさと略同じである。貫通孔１３ｈは、各主面部１１，１２の貫通孔１１ｈ，１２ｈに対応する位置に形成されている。また、貫通孔１３ｈは、切れ込み１３ｎと繋がっている。 Furthermore, a circular through hole 13h is formed at the tip of the intermediate portion 13. The size of the through hole 13h is approximately the same as the size of each of the through holes 11h and 12h. The through holes 13h are formed at positions corresponding to the through holes 11h and 12h of the respective main surface portions 11 and 12. Further, the through hole 13h is connected to the notch 13n.

アタッチメント１０は、第１主面部１１、中間部１３、及び第２主面部１２が、この順番で積層されて、中間部１３に対し各主面部１１，１２が溶接部Ｗにより固定されることにより、一体化されている（図３（ｂ）参照）。アタッチメント１０では、第１主面部１１、中間部１３、及び第２主面部１２が、平面視において、幅方向の中心が一致し、且つ、上底及び下底が重なるように積層されている。アタッチメント１０では、第１主面部１１と第２主面部１２と中間部１３の切れ込み１３ｎとにより区画された部分が、篏合穴２０となる。 The attachment 10 has a first main surface section 11, an intermediate section 13, and a second main surface section 12 stacked in this order, and each main surface section 11, 12 is fixed to the intermediate section 13 by a weld W. , are integrated (see FIG. 3(b)). In the attachment 10, the first main surface part 11, the intermediate part 13, and the second main surface part 12 are stacked so that the centers in the width direction coincide with each other and the upper and lower bases overlap in plan view. In the attachment 10, a portion defined by the first main surface portion 11, the second main surface portion 12, and the notch 13n of the intermediate portion 13 serves as the mating hole 20.

篏合穴２０は、挿入方向の寸法Ｘが突起部７の突出長より少しだけ短い。篏合穴２０は、突起部７のうち先端から付け根近傍までの範囲を嵌め込み可能である。篏合穴２０に対して奥まで突起部７を挿入した状態では、突起部７において幅方向に対向する側面（平面視において互いに等しい辺の側面）が篏合穴２０の内面に当接する。この状態で、第１主面部１１の固定用ネジ穴１５に対し固定用ネジ２５を螺合し、固定用ネジ２５の軸部先端を突起部７に押し付けることで、篏合穴２０に対して突起部７が強固に固定される。 The dimension X of the mating hole 20 in the insertion direction is slightly shorter than the protrusion length of the protrusion 7 . The fitting hole 20 is capable of fitting a portion of the protrusion 7 from the tip to the vicinity of the base. When the protrusion 7 is inserted deep into the mating hole 20 , side surfaces of the protrusion 7 that are opposite in the width direction (side surfaces with equal sides in plan view) abut against the inner surface of the mating hole 20 . In this state, by screwing the fixing screw 25 into the fixing screw hole 15 of the first main surface part 11 and pressing the shaft end of the fixing screw 25 against the projection 7, the fixing screw 25 is inserted into the fitting hole 20. The protrusion 7 is firmly fixed.

また、アタッチメント１０では、平面視において、各貫通孔１１ｈ，１２ｈ，１３ｈの中心及び外周が互いに一致している。つまり、アタッチメント１０では、貫通孔１１ｈ、貫通孔１３ｈ及び貫通孔１２ｈが繋がり、１つの貫通孔１６となっている。貫通孔１６は、アタッチメント１０の先端側に位置している。貫通孔１６の直径は、アタッチメント１０の厚さ方向に一定である。貫通孔１６の直径は、篏合穴２０の奥部分の幅よりも大きく、作業者が持ち歩くポンチ（棒材）３０にほぼ等しい。貫通孔１６の直径は例えば１３～１５ｍｍである。貫通孔１６にはポンチ３０を嵌め込み固定することができる。 Moreover, in the attachment 10, the center and outer periphery of each of the through holes 11h, 12h, and 13h coincide with each other in plan view. That is, in the attachment 10, the through hole 11h, the through hole 13h, and the through hole 12h are connected to form one through hole 16. The through hole 16 is located on the distal end side of the attachment 10. The diameter of the through hole 16 is constant in the thickness direction of the attachment 10. The diameter of the through hole 16 is larger than the width of the inner part of the mating hole 20, and is approximately equal to the punch (bar) 30 carried by the operator. The diameter of the through hole 16 is, for example, 13 to 15 mm. A punch 30 can be fitted and fixed into the through hole 16.

［実施形態の効果等］
本実施形態では、アタッチメント１０の篏合穴２０に反力受け５の突起部７を挿入することで、締付け対象のボルト（図５、図６において外筒部４の内側に位置するボルト（図示省略））から比較的離れたボルト３１にアタッチメントが届くようになる。そのため、このような状況でも、アタッチメント１０の外周面で反力を受けることができる。さらに、アタッチメント１０の貫通孔１６に棒材３０（又はピンなど）を嵌め込むことで、締付け対象のボルトから比較的離れた面（図７におけるプレート２２の外周面）に棒材３０を当てることができる。そのため、このような状況でも、棒材３０で反力を受けることができる。本実施形態によれば、様々な状況において反力を受けることが可能な反力受け用のアタッチメントを実現することができる。 [Effects of embodiments, etc.]
In this embodiment, by inserting the protrusion 7 of the reaction force receiver 5 into the mating hole 20 of the attachment 10, the bolt to be tightened (the bolt located inside the outer cylinder part 4 in FIGS. 5 and 6 (not shown) The attachment can now reach the bolt 31, which is relatively far away from (omitted)). Therefore, even in such a situation, the outer peripheral surface of the attachment 10 can receive a reaction force. Furthermore, by fitting the bar 30 (or a pin, etc.) into the through hole 16 of the attachment 10, the bar 30 can be applied to a surface relatively far away from the bolt to be tightened (the outer peripheral surface of the plate 22 in FIG. 7). I can do it. Therefore, even in such a situation, the bar 30 can receive the reaction force. According to this embodiment, it is possible to realize a reaction force receiving attachment that can receive reaction forces in various situations.

また、本実施形態では、突起部７のうち少なくとも先端から付け根近傍までの範囲が篏合穴２０に嵌め込まれるため、大きな反力を受ける場合であっても、突起部７に対するアタッチメント１０の固定状態を安定させることが可能である。 Furthermore, in this embodiment, at least the range from the tip to the vicinity of the base of the protrusion 7 is fitted into the mating hole 20, so even when receiving a large reaction force, the attachment 10 is fixed to the protrusion 7. It is possible to stabilize the

また、本実施形態では、第１主面部１１及び第２主面部１２の各々が、中間部１３に比べて厚みが小さい。そのため、突起部７にアタッチメント１０を取り付けた状態で、第１主面部１１及び第２主面部１２のどちらをプレート２２側にしても、アタッチメント１０がプレート２２と干渉することを回避することができる。そのため、作業者は上下を気にせずに、突起部７にアタッチメント１０を取り付けることができる。 Further, in this embodiment, each of the first main surface portion 11 and the second main surface portion 12 is thinner than the intermediate portion 13. Therefore, with the attachment 10 attached to the protrusion 7, interference between the attachment 10 and the plate 22 can be avoided regardless of which of the first main surface section 11 and the second main surface section 12 is on the plate 22 side. . Therefore, the operator can attach the attachment 10 to the protrusion 7 without worrying about the top and bottom.

また、本実施形態では、棒材３０が嵌め込まれる貫通孔１６の直径が、篏合穴２０の奥部分の幅よりも大きい。ここで、貫通孔１６の直径を小さくした方がアタッチメント１０のより先端に貫通孔１６を配置できる。しかし、本願発明者は、工事現場で作業者がよく持ち歩くポンチを棒材３０として利用できるようにした方が便利であると考えた、本実施形態では、このような考えに基づき、篏合穴２０の奥部分の幅よりも貫通孔１６の直径を長くしている。従って、作業者は別途に棒材を運ぶ必要がない。 Further, in the present embodiment, the diameter of the through hole 16 into which the bar 30 is fitted is larger than the width of the inner part of the mating hole 20. Here, if the diameter of the through hole 16 is made smaller, the through hole 16 can be placed closer to the tip of the attachment 10. However, the inventor of the present application thought that it would be more convenient to use the punch that workers often carry around at construction sites as the bar material 30.In this embodiment, based on this idea, The diameter of the through hole 16 is made longer than the width of the inner part of the hole 20. Therefore, the worker does not need to carry the bar separately.

［その他の実施形態］
上述の実施形態において、貫通孔１６の直径を篏合穴２０の奥部分の幅よりも短くして、アタッチメント１０のより先端に貫通孔１６を配置してもよい。また、貫通孔１６（貫通孔１３ｈ）は、切れ込み１３ｎと繋がっていなくてもよい。 [Other embodiments]
In the embodiment described above, the diameter of the through hole 16 may be made shorter than the width of the inner part of the mating hole 20, and the through hole 16 may be arranged at the tip of the attachment 10. Further, the through hole 16 (through hole 13h) does not need to be connected to the notch 13n.

上述の実施形態では、固定用ネジ穴１５を用いて突起部７にアタッチメント１０を固定したが、固定用ネジ穴１５以外の固定手段を用いて突起部７にアタッチメント１０を固定してもよい。 In the embodiment described above, the attachment 10 is fixed to the protrusion 7 using the fixing screw hole 15, but the attachment 10 may be fixed to the protrusion 7 using a fixing means other than the fixing screw hole 15.

上述の実施形態では、第１主面部１１と第２主面部１２とで平面形状は同じであるが、第１主面部１１と第２主面部１２とで平面形状が異なっていてもよい。例えば、図４において第２主面部１２の高さを低くしてもよい。また、上述の実施形態では、第１主面部１１と第２主面部１２とで厚みは同じであるが、第１主面部１１と第２主面部１２とで厚みが異なっていてもよい。 In the embodiment described above, the first main surface section 11 and the second main surface section 12 have the same planar shape, but the first main surface section 11 and the second main surface section 12 may have different planar shapes. For example, in FIG. 4, the height of the second main surface portion 12 may be reduced. Further, in the above embodiment, the first main surface section 11 and the second main surface section 12 have the same thickness, but the first main surface section 11 and the second main surface section 12 may have different thicknesses.

上述の実施形態において、アタッチメント１０は、溶接を行うことなく、切削のみで形成してもよい。 In the embodiments described above, the attachment 10 may be formed only by cutting without welding.
