Description
【０００１】[0001]
本考案は、螺子（ねじ）締め装置の改良に関する。 The present invention relates to an improvement of a screw (screw) tightening device.
【０００２】[0002]
図６に例示するように、二本を一組とする螺子ｂにより締結される部品ａであ って前記螺子ｂについて締結トルクの大きさを厳密に規定されているものが世に 数多く存在する。このような螺子ｂを人手により締結する場合は電気または圧縮 空気等を動力源としたトルクレンチが一般に用いられているが、要求される締結 トルクが比較的高い場合には一方の螺子ｂを先に締結する時のトルクで部品ａが 回転してしまい、他方の螺子ｂと螺子孔とが合わなくなってしまう。その対策と して 先ず一方の螺子ｂを仮締めし、次いで他方の螺子ｂを本締めしてから一方の 螺子ｂを本締めする、または 一方の螺子ｂの螺子孔にダミーピンを挿入して部品ａを回り止めし、この状 態で他方の螺子ｂを本締めし、次いでダミーピンを引き抜いて一方の螺子ｂを本 締めする 等のことがなされているが、このようなことでは工程が徒に多いために締結作業 に多大な手間と時間を必要とする。 As illustrated in FIG. 6, there are many parts a to be fastened by a set of two screws b, in which the tightening torque of the screw b is strictly defined. When such a screw b is manually tightened, a torque wrench that uses electricity or compressed air as a power source is generally used. However, when the required tightening torque is relatively high, one screw b is used first. The component a rotates due to the torque when it is fastened, and the other screw b and the screw hole do not match. As a countermeasure, first, one screw b is temporarily tightened, then the other screw b is finally tightened, then one screw b is finally tightened, or a dummy pin is inserted into a screw hole of one screw b to insert a component. Although a is prevented from rotating, the other screw b is finally tightened in this state, and then the dummy pin is pulled out and one screw b is finally tightened. Due to the large number of them, a lot of labor and time are required for the fastening work.
【０００３】[0003]
本考案は以上の点に鑑み、二本の螺子を同時に締めることができ、もって締結 作業を簡単に行なうことができる螺子締め装置を提供することを目的とする。 SUMMARY OF THE INVENTION In view of the above points, the present invention has an object to provide a screw tightening device capable of simultaneously tightening two screws, thereby facilitating the tightening work.
【０００４】[0004]
上記目的を達成するため、本考案の螺子締め装置は、一の動力源と、前記動力 源により回転せしめられる互いに平行な二本のビットと、を有することを特徴と する（請求項１）。また上記構成の螺子締め装置において、二本のビットをそれ ぞれ動力源の中心軸を中心として揺動自在に枢着し、前記二本のビットの間のピ ッチを可変としたことを特徴とする（請求項２）。 To achieve the above object, the screw tightening device of the present invention is characterized by having one power source and two parallel bits that are rotated by the power source (claim 1). In addition, in the screw tightening device having the above-mentioned configuration, two bits are pivotally attached to each of them so as to be swingable about the central axis of the power source, and the pitch between the two bits is variable. It is characterized (claim 2).
【０００５】[0005]
一の動力源により二本のビットを同時に回転させて二本の螺子を同時に締結す る。また締結に先立って二本のビットをそれぞれ動力源の中心軸を中心として揺 動させ、該二本のビットの間のピッチを二本の螺子の間の間隔に合わせる。 One power source rotates two bits at the same time and fastens two screws at the same time. Prior to fastening, the two bits are respectively swung around the central axis of the power source, and the pitch between the two bits is adjusted to the distance between the two screws.
【０００６】[0006]
つぎに本考案の実施例を図面にしたがって説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.
【０００７】 図１は当該螺子締め装置の外観を示し、図２は当該螺子締め装置の内部構造を 示している。 先ず、図２の内部構造において、１は動力源であり、動力源１が駆動すると駆 動ギヤ２が回転する。駆動ギヤ２に二個の従動ギヤ３，４がそれぞれ歯合してお り、従動ギヤ３，４が回転すると二本のビット５，６がそれぞれ回転する。二本 のビット５，６はそれぞれ動力源１の中心軸７に対して平行に配置され、よって 二本のビット５，６は互いに平行に配置されている。従動ギヤ３，４とビット５ ，６の間にそれぞれクラッチ機構８，９およびトルク調整機構１０，１１が介装 されている。FIG. 1 shows the external appearance of the screw tightening device, and FIG. 2 shows the internal structure of the screw tightening device. First, in the internal structure of FIG. 2, 1 is a power source, and when the power source 1 is driven, the drive gear 2 rotates. Two driven gears 3 and 4 are meshed with the drive gear 2, and when the driven gears 3 and 4 rotate, the two bits 5 and 6 respectively rotate. The two bits 5 and 6 are arranged parallel to the central axis 7 of the power source 1, so that the two bits 5 and 6 are arranged parallel to each other. Clutch mechanisms 8 and 9 and torque adjusting mechanisms 10 and 11 are interposed between the driven gears 3 and 4 and the bits 5 and 6, respectively.
【０００８】 上記の内部構造が図１に示したケースに収容されている。ケースは動力源１お よび駆動ギヤ２を収容した第一のケース１２と、一方の従動ギヤ３、クラッチ機 構８、トルク調整機構１０およびビット５を収容した第二のケース１３と、他方 の従動ギヤ４、クラッチ機構９、トルク調整機構１１およびビット６を収容した 第三のケース１４と、よりなっている。ビット５，６の先端はそれぞれ第二のケ ース１３または第三のケース１４から外部へ突出している。第一ないし第三のケ ース１２，１３，１４は何れも円筒体であって動力源１の中心軸７またはビット ５，６と同軸に配置されている。 第二のケース１３および第三のケース１４にそれぞれ第一のケース１２に対す る接続部１５，１６が設けられている。接続部１５，１６は環状体またはＣ字体 であって何れにしろ第一のケース１２の外周に回転自在に嵌合されており、よっ て第二のケース１３および第三のケース１４はそれぞれ第一のケース１２の回り を動力源１の中心軸７を中心として揺動することが可能である。これに伴って二 本のビット５，６もそれぞれ動力源１の中心軸７を中心として揺動することとな り、揺動角度に応じて二本のビット５，６の間のピッチが可変となっている。図 ３および図４はそれぞれ第一ないし第三のケース１２，１３，１４を上方から観 たところで、図３の場合が第一ないし第三のケース１２，１３，１４が一直線に 並んでピッチｐが最大となっており、図４の場合が第二のケース１３と第三のケ ース１４が互いに当接してピッチｐが最小となっている。The above internal structure is housed in the case shown in FIG. The case includes a first case 12 accommodating the power source 1 and the drive gear 2, a second case 13 accommodating one driven gear 3, a clutch mechanism 8, a torque adjusting mechanism 10 and a bit 5, and the other case. It comprises a driven case 4, a clutch mechanism 9, a torque adjusting mechanism 11 and a third case 14 accommodating the bit 6. The tips of the bits 5 and 6 respectively project from the second case 13 or the third case 14 to the outside. Each of the first to third cases 12, 13 and 14 is a cylindrical body and is arranged coaxially with the central axis 7 of the power source 1 or the bits 5 and 6. The second case 13 and the third case 14 are provided with connecting portions 15 and 16 for the first case 12, respectively. The connecting portions 15 and 16 are annular bodies or C-shaped bodies and are rotatably fitted to the outer circumference of the first case 12 in any case, so that the second case 13 and the third case 14 are respectively connected to the first case 12. It is possible to swing around one case 12 about the central axis 7 of the power source 1. Along with this, the two bits 5 and 6 also swing around the central axis 7 of the power source 1, and the pitch between the two bits 5 and 6 changes according to the swing angle. Has become. FIGS. 3 and 4 show the first to third cases 12, 13 and 14 viewed from above, respectively. In the case of FIG. 3, the first to third cases 12, 13 and 14 are arranged in a straight line at a pitch p. Is the maximum, and in the case of FIG. 4, the second case 13 and the third case 14 are in contact with each other and the pitch p is the minimum.
【０００９】 当該螺子締め装置は同時に回転する二本のビット５，６を有しており、よって 図６に例示した部品ａ等において二本の螺子を同時に締結することができる。ま た二本のビット５，６をそれぞれ動力源１の中心軸７を中心として揺動自在に枢 着してビット５，６の間のピッチｐを可変としたために、二本の螺子の間の間隔 が多少広くても狭くても、ピッチｐを間隔に合わせることにより二本の螺子を同 時に締結することができる。尚、図４の状態から更に小さなピッチｐを必要とす る場合は、図５に示すように、第二のケース１３または第三のケース１４に小径 の第四のケース１５および第五のケース１６を揺動自在に接続し、内部構造にお いて伝動機構の数を増やせば良い。The screw tightening device has two bits 5 and 6 that rotate at the same time. Therefore, two screws can be fastened at the same time in the part a and the like illustrated in FIG. Further, since the two bits 5 and 6 are pivotally mounted about the central axis 7 of the power source 1 so that the pitch p between the bits 5 and 6 is variable, the two bits 5 and 6 are The two screws can be fastened at the same time by adjusting the pitch p to the interval regardless of whether the interval is slightly wide or narrow. If a smaller pitch p is required from the state shown in FIG. 4, as shown in FIG. 5, the second case 13 or the third case 14 has a smaller diameter in the fourth case 15 and the fifth case. It is only necessary to connect 16 in a swingable manner and increase the number of transmission mechanisms in the internal structure.
【００１０】[0010]
本考案は次の効果を奏する。すなわち、一の動力源により二本のビットを同時 に回転させる構成であるために二本の螺子を同時に締結することができ、よって 締結作業を簡単に行なうことができる。また二本のビットをそれぞれ動力源の中 心軸を中心として揺動自在に枢着してビットの間のピッチを可変とした場合には 二本の螺子の間の間隔が多少広くても狭くても二本の螺子を同時に締結すること ができる。 The present invention has the following effects. That is, since the two bits are simultaneously rotated by one power source, the two screws can be fastened at the same time, so that the fastening work can be easily performed. If the two bits are pivotally attached to each other around the center axis of the power source so that the pitch between the bits can be varied, the gap between the two screws may be slightly wide or narrow. However, two screws can be fastened at the same time.
