(57) [Summary] (Modified) [Purpose] A screw tightening screwdriver that can adjust the position of the screw automatically when it is attached to an automatic machine. [Structure] The shaft 1 is provided with a hexagonal spherical portion 2, and the hexagonal spherical portion 2 is fitted and connected to the shaft of the motor 3 by a coupler 4 having a deep hexagonal hole that can slide back and forth. The shaft can move laterally only when the shaft 1 pushed out by the spring 5 is pushed in.
Description
【考案の詳細な説明】 本考案は組立機，調整機等機械に取り付けて使用する主として電動ネジ締め用 ドライバーに関するものである。[Detailed Description of the Invention] The present invention mainly relates to a screwdriver for electric screw tightening, which is used by being attached to a machine such as an assembling machine or an adjusting machine.
従来のこの種のドライバーは目的とするネジとの間に位置ずれを生じた場合， ネジ締めが正しく行われないことがあり，ネジ山のつぶれ，対象製品またはドラ イバー自体の破損に至ることがしばしばあった。 If a conventional screwdriver of this type is misaligned with the intended screw, the screw may not be tightened correctly, which may lead to crushing of the screw thread or damage to the target product or the driver itself. Was often there.
本考案の目的は上記従来方法の欠点を除き，幾らかの位置ずれであれば正しく ネジ締めされる軸調心形ドライバーを提供することにある。 An object of the present invention is to provide an axially aligned screwdriver which can be properly screw-fastened if there is some displacement, excluding the above-mentioned drawbacks of the conventional method.
以下，図示の実施例に基ずいて本考案を説明する。 The present invention will be described below based on the illustrated embodiment.
図１に示されるように本考案は，ネジ締めの回転軸となるシャフト１，該シャ フト１に回転を与えるモータ３，六角穴を備えシャフト１と該モータ３の軸を連 結するカップラ４，該カップラ４の六角穴にシャフト１を押し出すべく設けられ たスプリング５，前記シャフト１の一端を支える出力端軸受６，前記シャフト１ に直結されるビットチャック７，該ビットチャック７に取り付けられるビット８ ，上記構成部品を機能的に配置するためのフレーム９により構成される。 As shown in FIG. 1, according to the present invention, a shaft serving as a rotary shaft for screw tightening, a motor 3 for rotating the shaft 1, a hexagonal hole, and a coupler 4 for connecting the shaft 1 and the shaft of the motor 3 are provided. A spring provided to push out the shaft 1 into the hexagonal hole of the coupler 5, an output end bearing 6 for supporting one end of the shaft 1, a bit chuck 7 directly connected to the shaft 1, a bit attached to the bit chuck 7. 8. A frame 9 for functionally arranging the above components.
ここで，前記シャフト１は，カップラ４の六角穴にはまり込む部分を，軸が傾 いた状態でもシャフト１が回転できるように六角球形部分２（図２参照）を備え ，出力端軸受６においては太い軸径部分と細い軸径部分を備えている。 Here, the shaft 1 is provided with a hexagonal spherical portion 2 (see FIG. 2) so that the shaft 1 can rotate even when the shaft is tilted, and the output end bearing 6 has It has a thick shaft diameter part and a thin shaft diameter part.
上記構成においてシャフト１はスプリング５により常に押し出された状態でモ ータ３によって回転する。このときの出力端軸受６におけるシャフト１の軸径は 太い軸径部分にあり，該軸受部分での隙間は小さい。 ここで，図３に示される ようにビット８が目的とするネジに突き当たり，シャフト１が内側へ押し込まれ ると，出力端軸受６には細い軸径部分が入り込んでくるため該隙間は大きくなり ，隙間分だけシャフト１は横へ移動できる。 In the above structure, the shaft 1 is rotated by the motor 3 while being constantly pushed by the spring 5. At this time, the shaft diameter of the shaft 1 in the output end bearing 6 is in the thick shaft diameter portion, and the gap in the bearing portion is small. Here, as shown in FIG. 3, when the bit 8 hits the target screw and the shaft 1 is pushed inward, the output end bearing 6 has a small shaft diameter portion, so the gap becomes large. The shaft 1 can move laterally by the gap.
該シャフト１の移動はシャフトの前記六角球形部分２を支点としビット先端ま でを半径とした円周上で行われることから，シャフト１の長さを適当に設定すれ ば軸のずれによるシャフト１の傾きを実用上支障のない値におさえることができ る。 Since the movement of the shaft 1 is performed on the circumference with the hexagonal spherical portion 2 of the shaft as the fulcrum and the radius up to the tip of the bit, if the length of the shaft 1 is set appropriately, the shaft 1 will be displaced due to the axis deviation. The slope of can be suppressed to a value that does not hinder practical use.
本考案は上記のように構成されており，ネジとの位置ずれに対し，自動的に調 心できるので，自動組立機，回路基板の自動調整機等に取り付けて使用する用途 では便利であり，ビットを取り替えることにより六角ボルト，六角ナット等にも 応用でき，工業的価値は大きい。 Since the present invention is configured as described above and can automatically adjust the position shift with the screw, it is convenient for use by attaching it to an automatic assembly machine, an automatic circuit board adjuster, etc. By replacing the bit, it can be applied to hexagon bolts, hexagon nuts, etc., and has great industrial value.
