Description

本考案は、ボルトに関し、詳しくはアイボルトに関するものである。 The present invention relates to a bolt, and more particularly to an eyebolt.

従来、プラスチック射出成形機は、金型を簡単に取り替えるため、金型を装着する際、先端にリングを有するアイボルトと金型とを結合させ、そののちアイボルトの先端のリングと作業台とを結合させることによって金型を固定する。しかしながら、上述した固定方式は、アイボルトを締め付け、金型を一定の角度に固定した後、角度調整を行うことができないため、金型を強制的に回し、角度を換えると金型が緩んでアイボルトから逸脱することが起こりやすくなる。 Conventionally, in order to easily replace a mold, a plastic injection molding machine connects an eyebolt having a ring at the tip and the mold when the mold is mounted, and then connects the ring at the tip of the eyebolt and the work table. To fix the mold. However, in the above-described fixing method, the eye cannot be adjusted after the eyebolt is tightened and the mold is fixed at a certain angle. Therefore, if the mold is forcibly turned and the angle is changed, the mold loosens and the eyebolt Deviations from are likely to occur.

上述した欠点を改善するため、業者は研究および開発を進める。例えば特許文献１に開示されたアイボルト（eyebolt）は、リングとボルトが分離できるように設計されるため、ボルトと金型とを結合させた後、ボルトに対し、先端のリングを回転させることによって金型の角度を調整することができる。 In order to remedy the above-mentioned drawbacks, the merchant proceeds with research and development. For example, since the eyebolt disclosed in Patent Document 1 is designed so that the ring and the bolt can be separated, after the bolt and the mold are coupled, the ring at the tip is rotated with respect to the bolt. The mold angle can be adjusted.

しかしながら、上述した設計は型の角度を調整することができるが、ボルトをある程度まで締め付けると、ボルトのヘッド部でリングを押さえるため、リングは圧迫され、回転しにくくなり、組み立て、固定および調整作業に支障をきたすことが生じる。 However, the design described above can adjust the angle of the mold, but when the bolt is tightened to a certain extent, the ring is pressed by the head part of the bolt, so the ring is pressed and difficult to rotate, and assembly, fixing and adjustment work Cause trouble.

以下、本考案の実施形態によるアイボルトを図面に基づいて説明する。
（第１実施形態）
図１および図２に示すように、本考案の第１実施形態によるアイボルトは、リング１０、ワッシャ２０およびボルト３０を備える。 Hereinafter, an eyebolt according to an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
As shown in FIGS. 1 and 2, the eyebolt according to the first embodiment of the present invention includes a ring 10, a washer 20, and a bolt 30.

リング１０は、基部１２と、基部１２に位置する環状部１４とを有する。基部１２は第一貫通孔１２２を有する。第一貫通孔１２２は環状部１４から囲まれた区域に繋がる。環状部１４は第一貫通孔１２２に接する部位に装着空間１４１を有する。第一貫通孔１２２は内壁に環状に形成された突出壁部１２３を有する。突出壁部１２３は環状部１４から囲まれた区域に向かう表面が軸方向に対して傾斜した斜面１２３ａである。 The ring 10 has a base portion 12 and an annular portion 14 located on the base portion 12. The base 12 has a first through hole 122. The first through hole 122 is connected to the area surrounded by the annular portion 14. The annular portion 14 has a mounting space 141 at a portion in contact with the first through hole 122. The first through hole 122 has a protruding wall portion 123 formed in an annular shape on the inner wall. The protruding wall portion 123 is a slope 123a whose surface toward the area surrounded by the annular portion 14 is inclined with respect to the axial direction.

ワッシャ２０は、当接部２２およびマット部２４を有する。当接部２２は第二貫通孔２２１を有し、外径が突出壁部１２３の内径より小さい。マット部２４は当接部２２を囲むように形成され、外径が第一貫通孔１２２の孔径より小さい。図３に示すように、当接部２２の縦断面の軸方向の幅Ｈ１は第一貫通孔１２２の軸方向の深さＨ２より大きい。 The washer 20 has a contact portion 22 and a mat portion 24. The abutting portion 22 has a second through hole 221, and the outer diameter is smaller than the inner diameter of the protruding wall portion 123. The mat portion 24 is formed so as to surround the contact portion 22 and has an outer diameter smaller than the hole diameter of the first through hole 122. As shown in FIG. 3, the axial width H <b> 1 of the longitudinal section of the contact portion 22 is larger than the axial depth H <b> 2 of the first through hole 122.

ボルト３０は、相互に連結されたヘッド部３２およびシャフト３４を有する。ヘッド部３２は頂部の中央に六角形凹部３２１を有し、底部に斜面３２２を有する。斜面３２２は突出壁部１２３の斜面１２３ａに対応する。ヘッド部３２は外径がシャフト３４の外径より大きく、かつ環状部１４の内径より小さい。シャフト３４はねじ山を有する。 The bolt 30 has a head portion 32 and a shaft 34 connected to each other. The head portion 32 has a hexagonal concave portion 321 at the center of the top portion and a slope 322 at the bottom portion. The slope 322 corresponds to the slope 123 a of the protruding wall portion 123. The head portion 32 has an outer diameter larger than the outer diameter of the shaft 34 and smaller than the inner diameter of the annular portion 14. The shaft 34 has a thread.

上述した構造設計により、組み立てを行う際、リング１０の第一貫通孔１２２内にワッシャ２０を装着し、そののち環状部１４から囲まれた区域から第一貫通孔１２２および第二貫通孔２２１内にボルト３０のシャフト３４を差し込み、かつリング１０に突出させる。続いて、ワッシャ２０の当接部２２の一部分をシャフト２４と突出壁部１２３との間に位置させ、ヘッド部３２を装着空間１４１内に位置させる。このとき突出壁部１２３はヘッド部３２とマット部２４との間に位置する。一方、環状部１４の内径がヘッド部３２の外径より大きいため、リング１０内にボルト３０を装着する際、妨害を余計に受けることがない。突出壁部１２３上の軸方向に対して傾斜した斜面１２３ａは誘導効果を有するため、第一貫通孔１２２および第二貫通孔２２１内にシャフト３４を簡単に差し込むことができる。 Due to the structural design described above, when assembling, the washer 20 is mounted in the first through-hole 122 of the ring 10, and then in the first through-hole 122 and the second through-hole 221 from the area surrounded by the annular portion 14. The shaft 34 of the bolt 30 is inserted into the ring 10 and protruded to the ring 10. Subsequently, a part of the abutting portion 22 of the washer 20 is positioned between the shaft 24 and the protruding wall portion 123, and the head portion 32 is positioned in the mounting space 141. At this time, the protruding wall portion 123 is located between the head portion 32 and the mat portion 24. On the other hand, since the inner diameter of the annular portion 14 is larger than the outer diameter of the head portion 32, when the bolt 30 is mounted in the ring 10, the interference is not excessively received. Since the inclined surface 123 a inclined with respect to the axial direction on the protruding wall portion 123 has a guiding effect, the shaft 34 can be easily inserted into the first through hole 122 and the second through hole 221.

続いて、リング１０に突出したシャフト３４と型１００のねじ山１１０とを結合させ、そののち六角形凹部３２１に六角レンチ（図中未表示）を差し込み、ボルト３０を回して締め付ける。ボルト３０を締め付ければ、ボルト３０のヘッド部３２で装着空間１４１内の当接部２２の頂部を押さえ、ワッシャ２０の底部を金型１００の表面に当接させることによって型１００を連結することができる。続いて、リング１０の環状部１４と作業台（図中未表示）とを連結すれば、型１００を作業台に固定することができる。一方、当接部２２の縦断面の軸方向の幅Ｈ１は第一貫通孔１２２の軸方向の深さＨ２より大きく、突出壁部１２３の斜面１２３ａとヘッド部３２の斜面３２２とは相互に対応するため、ヘッド部３２およびマット部２４と突出壁部１２３との間に隙間を残すことによってワッシャ２０およびボルト３０に対し、リング１０を自由回転させることができる。金型１００と作業台とを連結した後でも、型１００の角度を簡単に調整し、組み立ておよび調整作業の効率を向上させることができる。 Subsequently, the shaft 34 protruding from the ring 10 and the thread 110 of the mold 100 are coupled, and then a hexagon wrench (not shown in the drawing) is inserted into the hexagonal recess 321 and the bolt 30 is turned to tighten. When the bolt 30 is tightened, the top portion of the contact portion 22 in the mounting space 141 is pressed by the head portion 32 of the bolt 30 and the bottom portion of the washer 20 is brought into contact with the surface of the mold 100 to connect the die 100. Can do. Subsequently, when the annular portion 14 of the ring 10 and the work table (not shown in the drawing) are connected, the mold 100 can be fixed to the work table. On the other hand, the axial width H1 of the longitudinal section of the contact portion 22 is larger than the axial depth H2 of the first through hole 122, and the inclined surface 123a of the protruding wall portion 123 and the inclined surface 322 of the head portion 32 correspond to each other. Therefore, the ring 10 can be freely rotated with respect to the washer 20 and the bolt 30 by leaving a gap between the head portion 32 and the mat portion 24 and the protruding wall portion 123. Even after the mold 100 and the work table are connected, the angle of the mold 100 can be easily adjusted to improve the efficiency of assembly and adjustment work.

（第２実施形態）
図４に示したのは本考案の第２実施形態である。第１実施形態との違いは、次の通りである。リング４０の突出壁部４６は表面が軸方向に直交する平面４６１であるのに対し、ボルト６０のヘッド部６２は底面が軸方向に直交する平面６２２である。上述したとおり、平面設計を採用すれば、ボルト６０を締め付ける際の力をワッシャ５０の当接部５４に均等に分布させ、アイボルトを組み立てる際の信頼性を向上させることができる。 (Second Embodiment)
FIG. 4 shows a second embodiment of the present invention. Differences from the first embodiment are as follows. The protruding wall portion 46 of the ring 40 is a flat surface 461 whose surface is orthogonal to the axial direction, while the head portion 62 of the bolt 60 is a flat surface 622 whose bottom surface is orthogonal to the axial direction. As described above, if the flat design is adopted, the force at the time of tightening the bolt 60 can be evenly distributed to the contact portion 54 of the washer 50, and the reliability at the time of assembling the eyebolt can be improved.

本考案は、金型１００と結合して使用されると限らず、または別のねじ孔を有する物体と結合して使用されてもよい。
以上、本考案は、上記実施形態になんら限定されるものではなく、考案の趣旨を逸脱しない範囲において種々の形態で実施可能である。 The present invention is not limited to be used in combination with the mold 100, or may be used in combination with an object having another screw hole.
