Description

本発明の実施形態は、複数部材をボルト、ナットなどの締結部材で接合する作業で用いられる同心位置決め仮固定治具に関する。   An embodiment of the present invention relates to a concentric positioning temporary fixing jig used in an operation of joining a plurality of members with a fastening member such as a bolt or a nut.

機械の製作や構造物の組み立てでは、複数の部材をボルト、ナット等の締結部材で連結することが多い。この場合、部材同士のボルト穴を同心に合わせてから部材を仮固定し、ボルト、ナットで締結する手順を踏むことになる。このような部材の締結作業では、部材のボルト穴を調芯する手順と、心が合った状態で位置決めしたまま仮固定する手順があり、それを実施するために２種類の治具を必要としていた。   In manufacturing a machine or assembling a structure, a plurality of members are often connected by fastening members such as bolts and nuts. In this case, the bolt holes of the members are concentrically aligned, the members are temporarily fixed, and the procedure of fastening with bolts and nuts is performed. In such a member fastening operation, there are a procedure of aligning the bolt holes of the member and a procedure of temporarily fixing while being positioned in a centered state, and two types of jigs are required to carry out the procedure. It was.

従来、組み立てる対象物によっては、１つの治具で調芯機能と仮固定機能を合わせ持った治具が用いられることがある。この種の治具としては、例えば、特許文献１には、電気自動車の電源装置の組み立てにおいて、電池スタックとブラケットの締結に用いる治具が開示されている。   Heretofore, depending on the object to be assembled, there is a case where a jig having the alignment function and the temporary fixing function with one jig is used. As a jig of this type, for example, Patent Document 1 discloses a jig used for fastening a battery stack and a bracket in assembling a power supply device of an electric vehicle.

しかしながら、締結対象となる部材には、実に様々な形状、構造のものがあり、多くの場合、調芯用の治具と仮固定用の治具を組み合わせているのが現状である。
二種類の治具を用いて締結作業を行う場合、それだけ手間と労力がかかるのが実情である。例えば、ボルト穴を同心に調整した後は、調芯用治具を取り外して仮固定治具を取り付けることになるが、場合によっては、取り付けた調芯用治具や仮固定治具が取り外せなくなったり、調芯用治具に緩みが生じて部材の位置がずれるなどの問題がある。 However, the members to be fastened have various shapes and structures, and in many cases, the alignment jig and the temporary fixation jig are combined in most cases.
In the case of performing a fastening operation using two types of jigs, it is a fact that much time and effort is required. For example, after adjusting the bolt holes concentrically, the alignment jig is removed and the temporary fixing jig is attached, but depending on the case, the attached aligning jig or temporary fixing jig can not be removed. In addition, there is a problem that the alignment jig is loosened to shift the position of the member.

本発明は、前記従来技術の有する問題点に鑑みなされたものであって、複数の部材をボルト、ナットで締結する際に、ボルト穴を同心に位置決めする操作と、部材を仮固定する操作を１つの治具で同時に行え、しかも、治具の取り付け、取り外しを容易にできるようにした同心位置決め仮固定治具を提供することを目的とする。   The present invention has been made in view of the problems of the prior art, and when fastening a plurality of members with bolts and nuts, an operation of concentrically positioning the bolt holes and an operation of temporarily fixing the members An object of the present invention is to provide a concentric positioning temporary fixing jig which can be simultaneously performed by one jig and can be easily attached and removed.

前記の目的を達成するために、本発明の実施形態に係る同心位置決め仮固定治具は、一方の部材と他方の部材の締結用穴を重ね合わせ、両部材を締結部材により組み付ける作業に用いられる治具であって、重なった締結用穴に一方の部材側から挿入可能な円筒形状のケースと、前記ケースに収納され傾斜面を有する軸部と、前記一方の部材と他方の部材の境目をまたぐ位置で、前記傾斜面に密着して前記ケース内に設けられ、前記他方の部材に向かって押し込まれる方向の前記軸部の軸方向の移動により半径方向外方にせり出される同心位置決めプレートと、前記ケースの先端に揺動可能に設けられ、前記軸部の軸方向の移動とともに当該軸部に押動されながら開き、前記他方の部材を載せて支持可能な一対の受け部材と、を備えたことを特徴とするものである。   In order to achieve the above object, the concentric positioning temporary fixing jig according to the embodiment of the present invention is used for an operation of overlapping fastening holes of one member and the other member and assembling both members by the fastening member. A jig is a cylindrical case which can be inserted from one member side into the overlapping fastening hole, a shaft portion housed in the case and having an inclined surface, and a boundary between the one member and the other member And a concentric positioning plate provided in the case in close contact with the inclined surface at the overlapping position, and projecting radially outward by axial movement of the shaft in a direction in which it is pushed toward the other member. A pair of receiving members provided swingably at the tip of the case and opened while being pushed by the shaft with the axial movement of the shaft and capable of mounting and supporting the other member Special It is an.

以下、本発明による同心位置決め仮固定治具の一実施形態について、添付の図面を参照しながら説明する。
（第１実施形態）
図１は、本実施形態による同心位置決め仮固定治具を用いて連結するエレベータのガイドレールと継目板を示す斜視図である。この実施形態では、ボルト、ナット等の締結部材により締結する２つの部材として、エレベータのガイドレールと継目板を例に説明する。 Hereinafter, an embodiment of a concentric positioning temporary fixing jig according to the present invention will be described with reference to the attached drawings.
First Embodiment
FIG. 1 is a perspective view showing a guide rail and a joint plate of an elevator connected using the concentric positioning temporary fixing jig according to the present embodiment. In this embodiment, a guide rail and a joint plate of an elevator will be described as an example of two members to be fastened by fastening members such as bolts and nuts.

図１において、参照番号10は、エレベータのガイドレールを示し、参照番号14は、継目板を示している。ガイドレール10は、フランジ11とウェブ12を有する横断面Ｔ字形のレールである。エレベータの昇降路では、複数本のガイドレール10を継目板14で継ぎ合わせることで、最下階から最上階まで延びる１本の長いガイドレールとして昇降路に設置される。 In FIG. 1, reference numeral 10 denotes a guide rail of the elevator, and reference numeral 14 denotes a joint plate. The guide rail 10 is a T-shaped cross section rail having a flange 11 and a web 12. In the elevator hoistway, by connecting a plurality of guide rails 10 with a joint plate 14, it is installed in the hoistway as a single long guide rail extending from the lower floor to the uppermost floor.

ガイドレール10の端部では、そのフランジ11に複数のボルト穴13が形成されている。同様に、継目板14にも、フランジ11のボルト穴13と同じ間隔で同じ穴径の複数のボルト穴15が形成されている。
図１において、参照番号20は、同心位置決め仮固定治具を示している。この同心位置決め仮固定治具20を用いて、ガイドレール10のボルト穴13に継目板14のボルト穴15が同心に合う状態を保つようにして、継目板14をガイドレール10に仮固定する。 At the end of the guide rail 10, a plurality of bolt holes 13 are formed in the flange 11 thereof. Similarly, in the joint plate 14, a plurality of bolt holes 15 of the same hole diameter are formed at the same intervals as the bolt holes 13 of the flange 11.
In FIG. 1, reference numeral 20 indicates a concentric positioning temporary fixing jig. The joint plate 14 is temporarily fixed to the guide rail 10 by using the concentric positioning temporary fixing jig 20 so that the bolt holes 15 of the joint plate 14 are concentrically aligned with the bolt holes 13 of the guide rail 10.

次に、図２は、本実施形態による同心位置決め仮固定治具20の構成を示す縦断面図である。 この同心位置決め仮固定治具20は、軸部21と、円筒ケース23と、軸部21によって半径外方向に迫り出される同心位置決めプレート26a、26bを有している。
図２に示されるように、軸部21の上端部には、軸部21を押し込む力を受け易いように、フランジ部25が形成されている。軸部21の下半分は、円筒ケース23に収容されている。この円筒ケース23の長さは、重なり合ったガイドレール10のフランジ11と継目板14の厚さに応じた長さになっている。軸部21は、その先端に向かって連続的に径が小さくなっていく円錐形状を有しており、先端には押動端部22が同軸に設けられている。対をなして軸心に対称に配置されている同心位置決めプレート26a、26bの内側面は、軸部21のテーパ面（傾斜面）に密着しており、軸部21が押し込められると、同心位置決めプレート26a、26bは、円筒ケース23内部から半径外方向に押し出されるようになっている。また、同心位置決めプレート26a、26bの外周面は、樹脂などからなるガード部材27a、27bで保護され、ボルト穴13、15の内周面と同じ曲率の曲面を有している。この実施形態では、同心位置決めプレート26a、26bは２つで対をなしているが、これに限定されるものではない。３つ、４つで対をなすようにしてもよい。 Next, FIG. 2 is a longitudinal cross-sectional view which shows a structure of the concentric positioning temporary fixing jig 20 by this embodiment. The concentric positioning temporary fixing jig 20 includes a shaft portion 21, a cylindrical case 23, and concentric positioning plates 26 a and 26 b pushed outward in the radial direction by the shaft portion 21.
As shown in FIG. 2, a flange portion 25 is formed at the upper end portion of the shaft portion 21 so as to easily receive a force for pushing the shaft portion 21. The lower half of the shaft 21 is accommodated in a cylindrical case 23. The length of the cylindrical case 23 corresponds to the thickness of the flanges 11 and the joint plates 14 of the overlapping guide rails 10. The shaft portion 21 has a conical shape whose diameter decreases continuously toward its tip, and a pressing end 22 is coaxially provided at the tip. The inner side surfaces of the concentric positioning plates 26a and 26b arranged symmetrically about the axis in a pair are in close contact with the tapered surface (inclined surface) of the shaft 21, and when the shaft 21 is pushed in, concentric positioning is performed The plates 26a and 26b are pushed radially outward from the inside of the cylindrical case 23. The outer peripheral surface of the concentric positioning plate 26a, 26b is protected by guard members 27a, 27b made of resin or the like, and has a curved surface having the same curvature as the inner peripheral surface of the bolt holes 13, 15. In this embodiment, the concentric positioning plates 26a, 26b are paired in two but not limited thereto. Three or four may be paired.

円筒ケース23の上端は、上プレート33と一体になっており、上プレート33には、軸部21の移動を可能になる穴29が形成されている。軸部21の上半分は、上プレート33から突き出るようになっている。円筒ケース23の下端には、継目板14の仮固定並びに脱落防止のために、開閉式の継目板受け部材28a、28bがピン31a、31bを介して揺動可能に取り付けられている。   The upper end of the cylindrical case 23 is integrated with the upper plate 33, and the upper plate 33 is formed with a hole 29 which allows the shaft 21 to move. The upper half of the shaft 21 projects from the upper plate 33. At the lower end of the cylindrical case 23, in order to temporarily fix the joint plate 14 and to prevent the joint plate 14 from coming off, an openable joint plate receiving member 28a, 28b is pivotably attached via pins 31a, 31b.

開閉式の継目板受け部材28a、28bは、軸部21の軸線に関して対称位置に配置されており、軸部21の押動端部22が近接し、若しくは接触しても押動させていない状態では、図２に示されるように、継目板受け部材28a、28bは閉じた状態になっている。押動端部22の先端は円錐面30になっており、この円錐面30の頂点は、継目板受け部材28a、28bの間を通る線上にある。円錐面30は、軸部21が押し込まれるにしたがって継目板受け部材28a、28bの上端に均等に突き当たり、継目板受け部材28a、28bに開く作用を及ぼすようになっている。この実施形態では、継目板受け部材28a、28bは２つで一組になるが、これに限定されるものではない。３つ、４つで一組になるようにすることも可能である。   The openable and closable joint plate receiving members 28a and 28b are disposed at symmetrical positions with respect to the axis of the shaft 21, and are not pressed even if the pressing end 22 of the shaft 21 approaches or contacts. Then, as shown in FIG. 2, the joint plate receiving members 28a and 28b are in the closed state. The tip of the pushing end portion 22 is a conical surface 30, and the apex of the conical surface 30 is on a line passing between the joint plate receiving members 28a and 28b. The conical surface 30 uniformly abuts on the upper ends of the joint plate receiving members 28a and 28b as the shaft portion 21 is pushed, and has an effect of opening the joint plate receiving members 28a and 28b. In this embodiment, the joint plate receiving members 28a and 28b are a pair, but not limited thereto. It is also possible to make it a set of three or four.

本実施形態による複数部材の同心位置決め仮固定治具は、以上のように構成されるものであり、次に、ガイドレール10と継目板14との組み付け作業との関連において、その作用および効果について説明する。
図３は、ガイドレール10と継目板14に取り付ける前の同心位置決め仮固定治具20を示す図である。
まず、ボルト穴13、15が合うように、ガイドレール10に継目板14を重ねる。このとき、ガイドレール10のボルト穴13と、継目板14のボルト穴15は、厳密に同心位置になくてもよい。その後、同心位置決め仮固定治具20は、ボルト穴13、15に挿入される。同心位置決めプレート26a、26bは、円筒ケース23内で引っ込んだ位置にあり、継目板受け部材28a、28bは、閉じている。 The concentric positioning temporary fixing jig for a plurality of members according to the present embodiment is configured as described above. Next, in relation to the assembling operation of the guide rail 10 and the joint plate 14, its action and effect explain.
FIG. 3 is a view showing the concentric positioning temporary fixing jig 20 before the guide rail 10 and the joint plate 14 are attached.
First, the seam plate 14 is superimposed on the guide rail 10 so that the bolt holes 13 and 15 are aligned. At this time, the bolt holes 13 of the guide rail 10 and the bolt holes 15 of the joint plate 14 may not be strictly concentric. Thereafter, the concentric positioning temporary fixing jig 20 is inserted into the bolt holes 13 and 15. The concentric positioning plates 26a, 26b are in the retracted position in the cylindrical case 23, and the joint plate receiving members 28a, 28b are closed.

次に、図４は、ガイドレール10にセットした直後の同心位置決め仮固定治具20を示す。上プレート33がボルト穴13の開口回りに着座すると、同心位置決めプレート26a、26bは、継目板14とガイドレール10のフランジ11の境目に位置する。   Next, FIG. 4 shows the concentric positioning temporary fixing jig 20 immediately after being set to the guide rail 10. When the upper plate 33 is seated around the opening of the bolt hole 13, the concentric positioning plates 26 a and 26 b are located at the boundary between the joint plate 14 and the flange 11 of the guide rail 10.

次いで、図５は、軸部21を押し込んだときの同心位置決め仮固定治具20の動作を示す図である。軸部21の押し込みによって、同心位置決めプレート26a、26bは半径方向外方にせり出し、ボルト穴13、15の内周面に押し付けられる。これによって、継目板14はわずかに動き、ボルト穴13、15に、ずれがあれば矯正され、同心に位置決めされることになる。
ここで、ガイドレール10のボルト穴13、継目板14のボルト穴15は、図１に示されているように複数ある。同心位置決め仮固定治具20を取り付ける前の準備段階で、ボルト穴13とボルト穴14を大まかに合わせておけば、１つあるいは２つの少数の同心位置決め仮固定治具20を取り付けるだけで、残りの継目板14のボルト穴15についても同心にすることが可能である。 Next, FIG. 5 is a view showing an operation of the concentric positioning temporary fixing jig 20 when the shaft portion 21 is pushed. By pushing the shaft portion 21, the concentric positioning plates 26 a, 26 b are pushed radially outward and pressed against the inner peripheral surfaces of the bolt holes 13, 15. As a result, the joint plate 14 moves slightly, and the bolt holes 13 and 15 will be corrected and positioned concentrically if there is any deviation.
Here, there are a plurality of bolt holes 13 of the guide rail 10 and a plurality of bolt holes 15 of the joint plate 14 as shown in FIG. If the bolt hole 13 and the bolt hole 14 are roughly aligned in the preparation step before attaching the concentric positioning temporary fixing jig 20, only by attaching one or two few concentric positioning temporary fixing jigs 20, the remaining The bolt holes 15 of the joint plate 14 can also be concentric.

このような同心位置決め動作と同時並行して、継目板受け部材28a、28bが開き、継目板14がその上に載ることで下から支えられるようになっている。したがって、継目板受け部材28a、28bによって、継目板14の脱落を防止しながら、ガイドレール10に対して継目板14の仮固定を行うことができる。
その後、芯の一致したボルト穴13、15に図示しないボルトを挿入しナットを締め付けて本固定が行われる。 Concurrently with such a concentric positioning operation, the joint plate receiving members 28a and 28b are opened, and the joint plate 14 is supported thereon by being mounted thereon. Therefore, the seam plate 14 can be temporarily fixed to the guide rail 10 while preventing the seam plate 14 from falling off by the seam plate receiving members 28 a and 28 b.
Thereafter, a bolt (not shown) is inserted into the bolt holes 13 and 15 in which the cores coincide with each other, and the nut is tightened to carry out the final fixation.

なお、同心位置決め仮固定治具20を取り外すには、軸部21を引き抜けば、同心位置決めプレート26a、26bは引っ込み、継目板受け部材28a、28bは閉じるので、簡単に取り出すことができる。   In order to remove the concentric positioning temporary fixing jig 20, if the shaft portion 21 is pulled out, the concentric positioning plates 26a and 26b are retracted and the joint plate receiving members 28a and 28b are closed, so that they can be easily taken out.

以上説明したように、本実施形態の同心位置決め仮固定治具20によれば、軸部21を押し込むことによって、ガイドレール10のボルト穴13と継目板14のボルト穴15を同軸に調芯すると同時に、継目板14の仮固定を行えるので、調芯と仮固定を別々の治具を用いることなく実現することができる。   As described above, according to the concentric positioning temporary fixing jig 20 of the present embodiment, when the bolt hole 13 of the guide rail 10 and the bolt hole 15 of the joint plate 14 are coaxially aligned by pushing the shaft portion 21. At the same time, since the joint plate 14 can be temporarily fixed, alignment and temporary fixation can be realized without using separate jigs.

次に、図６、図７は、ボルト穴13、15の内径が異なる場合の同心位置決め仮固定治具20の調芯動作を示す図である。図６に示すボルト穴13、15に比べて、図７に示すボルト穴13、15の内径は小さくなっている。   Next, FIGS. 6 and 7 are views showing the alignment operation of the concentric positioning temporary fixing jig 20 when the inner diameters of the bolt holes 13 and 15 are different. The inner diameter of the bolt holes 13 and 15 shown in FIG. 7 is smaller than that of the bolt holes 13 and 15 shown in FIG.

軸部21は、適用可能な穴径をカバーする範囲が傾斜面としてのテーパ面になっており、ボルト穴13、15の内径が異なっても、軸部21の押し込み量が異なってくるだけであるので、同じ同心位置決め仮固定治具20を用いて、様々なサイズのボルト穴13、15にも対応することが可能である。   The shaft 21 has a tapered surface as an inclined surface in a range covering an applicable hole diameter, and even if the inner diameters of the bolt holes 13 and 15 are different, the pressing amount of the shaft 21 is different. As it is, it is possible to use the same concentric positioning temporary fixing jig 20 to cope with bolt holes 13 and 15 of various sizes.

（第２実施形態）
次に、本発明の第２実施形態による本発明による複数部材の同心位置決め仮固定治具ついて、図８並びに図９を参照して説明する。 Second Embodiment
Next, a concentric positioning temporary fixing jig according to a second embodiment of the present invention will be described with reference to FIGS. 8 and 9 according to a second embodiment of the present invention.

この第２実施形態は、軸部21を押し込んだ後、同心位置決めプレート26a、26bが退動せず、また、継目板受け部材28a、28bが閉じないように、軸部21の押し込み量を維持、調整できるようにした実施の形態である。   In the second embodiment, the amount of pushing of the shaft portion 21 is maintained so that the concentric positioning plates 26a and 26b do not move back and the joint plate receiving members 28a and 28b do not close after the shaft portion 21 is pushed in. This is an embodiment that can be adjusted.

図８に示すのは、継目板受け部材28a、28bを開く押動端部22に周方向の複数条の溝32を形成した実施の形態である。軸部21を押し込み、継目板受け部材28a、28bを開くと、図８に示されるように、押動端部22は、開いた継目板受け部材28a、28bの端部の間から下に突き出ることなる。このとき、継目板受け部材28a、28bの端部にある角部が溝32に係合するとともに、継目板14の重みで食い込むので、継目板受け部材28a、28bの開度が保たれるように軸部21の押し込み量を維持することができる。軸部21の押し込み量を調整したい場合には、係合する溝32の位置を変えればよい。
次に、図９は、変形例として、押動端部22に溝32の代わりに雄ねじ34を形成した実施の形態である。この場合、円筒ケース23には、雌ねじが形成されている。
この変形例では、軸部21を回しながら押し込み、位置決めプレート26a、26bをせり出すとともに継目板受け部材28a、28bを開くことになる。押動端部22がねじになっているので、軸部21の位置を保持することができ、継目板受け部材28a、28bの開度が保たれるように軸部21の押し込み量を維持することができる。軸部21の押し込み量の調整も容易である。 FIG. 8 shows an embodiment in which a plurality of grooves 32 in the circumferential direction are formed in the pushing end portion 22 for opening the joint plate receiving members 28a and 28b. Pushing the shank 21 and opening the seam plate receiving members 28a and 28b causes the pushing end 22 to project downward from between the ends of the open seam plate receiving members 28a and 28b, as shown in FIG. It will be different. At this time, since the corner portions at the ends of the joint plate receiving members 28a and 28b engage with the grooves 32 and bite by the weight of the joint plate 14, the opening degree of the joint plate receiving members 28a and 28b is maintained The pressing amount of the shaft 21 can be maintained. When it is desired to adjust the pressing amount of the shaft portion 21, the position of the groove 32 to be engaged may be changed.
