【産業上の利用分野】[Industrial applications]

本考案は、機械装置等の組立に際し、二つの部品を締付固定する六角ボルト及 び六角ナットの回り止め装置に関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hexagon bolt and a hexagon nut detent device for tightening and fixing two parts when assembling a mechanical device or the like.

【0002】[0002]

【従来の技術】[Prior Art]

例えば、駆動軸と従動軸を、自在継手を介して連結する場合など、軸のフラン ジと継手のフランジとを六角ボルト及び六角ナットを用いて締付固定する。しか しながら、このような可動部分では、常に応力や振動がかかるので、六角ボルト 及び六角ナットを単に締め付けた状態でおいたのでは、直ぐに弛みが生じてしま う。そこで何らかの弛み止め(回り止め)が必要である。 For example, when the drive shaft and the driven shaft are connected via a universal joint, the flange of the shaft and the flange of the joint are tightened and fixed using hexagon bolts and hexagon nuts. However, since stress and vibration are constantly applied to such moving parts, if the hexagon bolts and hexagon nuts are simply tightened, looseness will occur immediately. Therefore, some kind of slack stop (rotation stop) is necessary.

【0003】 従来の回り止めとしては、図6乃至図9に示したような方法が採られていた。 図6〜図9において、1及び2は互いに締付固定する被締付物としてのフランジ 、3はフランジ1,2に合わせ穿設された孔に通した六角ボルト(以下単にボル トという)、4はボルト3にねじ込まれた六角ナット(以下単にナットという) である。As a conventional detent, a method as shown in FIGS. 6 to 9 has been adopted. 6 to 9, 1 and 2 are flanges as objects to be tightened and fixed to each other, 3 is a hexagonal bolt (hereinafter, simply referred to as a bolt) which is passed through a hole formed in accordance with the flanges 1 and 2, Reference numeral 4 denotes a hexagon nut (hereinafter simply referred to as nut) screwed into the bolt 3.

【0004】 先ず、図6(a),(b)に示したものは、L形金具5をナット4の側面とボルト3 の先端とにそれぞれ溶接固定するものである。6は溶接部を示している。また、 図6(c)では、複数のボルト頭部3aに共通の線状金具7を溶接固定している。し かしながら、この方法は、ボルト3又はナット4にL形金具5や線状金具7を直 接溶接するので、ボルト、ナットの機械的強度が低下するという問題がある外、 溶接する際にL形金具5や線状金具7が動き易く、作業性が悪いという問題もあ った。First, in the structure shown in FIGS. 6A and 6B, the L-shaped metal fitting 5 is welded and fixed to the side surface of the nut 4 and the tip of the bolt 3, respectively. Reference numeral 6 indicates a welded portion. Further, in FIG. 6C, the common linear metal fitting 7 is welded and fixed to the plurality of bolt heads 3a. However, this method directly welds the L-shaped metal fitting 5 and the linear metal fitting 7 to the bolt 3 or the nut 4, so that there is a problem that the mechanical strength of the bolt and the nut is reduced. In addition, the L-shaped metal fitting 5 and the linear metal fitting 7 are easily moved, which causes a problem of poor workability.

【0005】 図7に示したものは、溶接時にI形金具8がセットし易いように、ボルト3の 先端に割り溝を入れたものである。このようにすれば、金具8が動かないので溶 接の作業性はよくなる。しかし、ボルトの先端に機械加工を施す必要があるため コスト高になると共に、図6の場合と同様に、ボルト、ナットの機械的強度が低 下する。The one shown in FIG. 7 has a split groove at the tip of the bolt 3 so that the I-shaped metal fitting 8 can be easily set during welding. In this way, the metal fitting 8 does not move, and the workability of welding is improved. However, since it is necessary to machine the tip of the bolt, the cost becomes high, and the mechanical strength of the bolt and the nut decreases as in the case of FIG.

【0006】 図8に示したものは、締め付けたナット4(又はボルト頭部)の一外縁部に回 り止め金具9を当接し、この金具9をフランジ1(又は2)に溶接固定するもの である。しかし、この場合も、溶接時の金具9の固定が大変で、作業性がよくな い。The one shown in FIG. 8 is one in which an anti-rotation metal fitting 9 is brought into contact with one outer edge portion of the tightened nut 4 (or bolt head), and the metal fitting 9 is welded and fixed to the flange 1 (or 2). Is. However, also in this case, fixing the metal fitting 9 at the time of welding is difficult and workability is not good.

【0007】 図9に示したものは、2つのボルトにまたがった座金10を敷いて、ボルト、ナ ットを締め付け、その後、座金10の端部をナット4(又はボルト頭部)の辺部に 沿って折り曲げて、回らないようにしたものである。しかしこの場合、ねじ寸法 が大きいと、締付トルクによって座金が変形し、使用不可能となる。そこで、変 形しにくいように座金の板厚を厚くすると、変形はなくなるが、折り曲げ加工が 困難になる。In the structure shown in FIG. 9, a washer 10 straddling two bolts is laid, the bolts and nuts are tightened, and then the end of the washer 10 is attached to the side of the nut 4 (or bolt head). It is bent along the line to prevent it from turning. However, in this case, if the screw size is large, the washer will be deformed by the tightening torque, making it unusable. Therefore, if the washer plate is thickened so that it is not easily deformed, the deformation disappears, but the bending process becomes difficult.

【考案が解決しようとする課題】[Problems to be solved by the device]

以上のように、従来の各種回り止め方法には、ボルト、ナットに対して直接溶 接が行われるので機械的強度が低下し、また再使用が不可能であったり、溶接時 の作業性が悪く、固定するための治具等を必要とするなどの問題があった。 As described above, in the various conventional detent methods, the bolts and nuts are directly welded to each other, so that the mechanical strength is lowered, the reuse is impossible, and the workability during welding is reduced. Unfortunately, there was a problem that a jig or the like for fixing was required.

【0009】 本考案は、上記従来技術の問題点を解決しようとするもので、ボルト、ナット に直接溶接を行うことなく、かつ溶接の作業性が良好な六角ボルト及び六角ナッ トの回り止め装置を提供することを目的とする。The present invention is intended to solve the above-mentioned problems of the prior art. Hexagon bolts and hexagon nut detent devices that do not directly weld to bolts and nuts and have good welding workability. The purpose is to provide.
