【産業上の利用分野】[Industrial applications]

本考案は樹脂製の帯にねじを一定間隔で一列状に植設した連結ねじの締付に使 用されるねじ締め機に関するものである。 The present invention relates to a screw tightening machine used for tightening connecting screws in which screws are planted in a row in a resin band at regular intervals.

【0002】[0002]

【従来の技術】[Prior art]

上記のように使用されるねじ締め機は、一般に図4に示すように電動機部31 とねじ締めアタッチメント30をカップリング32で連結して構成されており、 長さの異なるねじを締め付けるには、ねじの長さによっては数種類のアジャスタ を滑動部材の先端に取り付ける必要があり、それに応じて係止部材を操作してね じの締付深さを調節している。従来では、前記係止部材の操作に対して目安とな るものがなく、試し締めの繰り返しによってねじの締付深さを調節していた。 The screw tightener used as described above is generally configured by connecting a motor part 31 and a screw tightening attachment 30 with a coupling 32 as shown in FIG. 4, and in order to tighten screws of different lengths, Depending on the length of the screw, several types of adjusters must be attached to the tip of the sliding member, and the locking member is operated accordingly to adjust the tightening depth of the screw. Conventionally, there is no reference for the operation of the locking member, and the tightening depth of the screw is adjusted by repeating the trial tightening.

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

従来のねじ締め機では、上記したように長さの異なるねじを締め付けるために アジャスタを使用する際のねじの締め付け深さの調節は試し締めの繰り返しによ って行われていたが、この方法では調節に時間がかかり、作業効率が悪くなると いう欠点があった。 本考案の目的は、アジャスタを使用する際のねじの締付深さの調節に要する時 間が少ないねじ締め機を構成する事にある。 In the conventional screw tightening machine, adjustment of the screw tightening depth when using the adjuster to tighten screws with different lengths was performed by repeating trial tightening as described above. However, there was a drawback that adjustment took time and work efficiency deteriorated. An object of the present invention is to construct a screw tightener that requires less time to adjust the screw tightening depth when using an adjuster.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的は、締め付けるねじの長さによって使用するアジャスタが決まってい る事から、締め付けるねじの長さに応じた目盛りをカップリングに付す事によっ て達成される。 Since the adjuster to be used is determined by the length of the screw to be tightened, the above object can be achieved by attaching a scale according to the length of the screw to be tightened to the coupling.

【0005】[0005]

【作用】[Action]

上記のようにカップリングに付された目盛りは、長さの異なるねじを締め付け るためにアジャスタを使用する際のねじの締付深さの調節において、係止部材の 操作の目安となる。 The scale attached to the coupling as described above serves as a guide for operating the locking member when adjusting the screw tightening depth when the adjuster is used to tighten screws having different lengths.

【実施例】【Example】

本考案のねじ締め機の一実施例を図1〜図3に示す。 図において、電動機部1には電動機2と、該電動機2の回転動力を伝達する変 速歯車3、端部に傾斜した爪部4を有する変速歯車5、該変速歯車5の爪部4に 係合する爪部6を後端部に設け、先端部の内周にはビット7の角軸8に回転動力 を伝達する特定深さの角孔9を有し、ビット7の角軸8の特定位置に設けた溝1 0と係合する位置に小孔11を貫通させてボール12を埋設し、外周部にはビッ ト7の把持部13を装着したソケット14が配設されている。ソケット14は変 速歯車5とメタル15にて回転可能に軸支され、弾性体16に付勢されて変速歯 車5の回転動力をビット7に伝達する。ビット7の把持部13は、ピース17と バネ18および止め輪19から成り、ピース17はソケット14外周に滑動可能 に取り付けられ、内周部の前端側に大径部20を有し、該前端側をソケット14 に嵌着された止め輪19で係止され、後端はバネ18で付勢されている。 An embodiment of the screw tightener of the present invention is shown in FIGS. In the figure, the electric motor unit 1 includes an electric motor 2, a variable speed gear 3 for transmitting rotational power of the electric motor 2, a speed change gear 5 having a claw 4 inclined at an end thereof, and a claw 4 of the speed change gear 5. The mating claw portion 6 is provided at the rear end, and the inner periphery of the tip has a square hole 9 of a specific depth for transmitting rotational power to the angular shaft 8 of the bit 7, and the angular shaft 8 of the bit 7 is specified. A ball 12 is embedded by penetrating a small hole 11 at a position where it engages with a groove 10 provided at a position, and a socket 14 having a grip 13 of a bit 7 is mounted on the outer peripheral portion thereof. The socket 14 is rotatably supported by the variable speed gear 5 and the metal 15, and is urged by the elastic body 16 to transmit the rotational power of the speed change gear 5 to the bit 7. The gripping portion 13 of the bit 7 is composed of a piece 17, a spring 18 and a retaining ring 19. The piece 17 is slidably attached to the outer circumference of the socket 14 and has a large diameter portion 20 on the front end side of the inner circumference. The side is locked by a retaining ring 19 fitted in the socket 14, and the rear end is biased by a spring 18.

【0007】 21は米国特許4059034号に開示されているねじ締めアタッチメントで あり(詳細は図示しない)、22は連結ねじ23を抱えねじ送り機構を内蔵した 滑動部材で、ケーシング24内を滑動可能であると共に該ケーシング24の先端 より常時突出するようにバネ25にて付勢され収納されている。ケーシング24 はカップリング26を介して電動機部1に取付けられ、カップリング26は外周 に滑動部材22の突部22aと係合してねじの締付深さを制限する係止部材27 を螺着し、ビット7の把持部13を操作するための開口部28が設けられている 。Reference numeral 21 is a screw tightening attachment disclosed in US Pat. No. 4,590,034 (details not shown), and reference numeral 22 is a sliding member that holds a connecting screw 23 and has a screw feed mechanism built therein, which is slidable in a casing 24. In addition, the housing 25 is biased by a spring 25 so as to always project from the tip of the casing 24. The casing 24 is attached to the electric motor unit 1 via a coupling 26, and the coupling 26 is screwed on the outer periphery thereof with a locking member 27 that engages with the projection 22a of the sliding member 22 and limits the tightening depth of the screw. However, an opening 28 for operating the grip portion 13 of the bit 7 is provided.

【0008】 ねじを締め付けるには電動機2を回転させ、該回転動力を変速歯車3、5、弾 性体16の摩擦力によってソケット14を介しビット7に伝達する。次に滑動部 材22の先端を被締付部材に当て、電動機部1を押し付けると、滑動部材22が バネ25の付勢力に対抗しながらケーシング24内に退入し、連結ねじ23のね じがビット7軸線上に送られる。さらに電動機部1を押し付けると、ねじ頭部の 十字穴と、回転しているビット7が嵌合し、ねじが該ねじを連結している連結帯 23aを突き抜ける反力でソケット14端部の爪部6と変速歯車5の爪部4が嵌 合して電動機2の回転動力を伝達し、ねじを締め付け、滑動部材22後端の突部 22aと係止部材27が当接する事によりねじの締付深さが制限され、変速歯車 5後端の爪部4の傾斜の分力で、ソケット14の爪部6が離脱しねじの締め付け が終わる。締付終了後被締付部材からねじ締め機本体を離すと、滑動部材22は バネ25に付勢され元の位置に戻る。To tighten the screw, the electric motor 2 is rotated, and the rotational power is transmitted to the bit 7 via the socket 14 by the frictional force of the speed change gears 3, 5, and the elastic body 16. Next, when the tip of the sliding member 22 is applied to the tightened member and the electric motor unit 1 is pressed, the sliding member 22 retracts into the casing 24 against the biasing force of the spring 25, and the screw of the connecting screw 23 is pushed. Are sent on the bit 7 axis. When the electric motor part 1 is further pressed, the cross hole of the screw head and the rotating bit 7 are fitted, and the screw penetrates the connecting band 23a connecting the screw, and the claw at the end of the socket 14 is pressed by the reaction force. The portion 6 and the claw portion 4 of the speed change gear 5 are fitted to each other to transmit the rotational power of the electric motor 2, tighten the screw, and the protrusion 22a at the rear end of the sliding member 22 and the locking member 27 come into contact with each other to tighten the screw. The attachment depth is limited, and the claw portion 6 of the socket 14 is disengaged by the component force of the inclination of the claw portion 4 at the rear end of the speed change gear 5, and the tightening of the screw is completed. When the screw tightener main body is separated from the member to be tightened after the tightening is completed, the sliding member 22 is urged by the spring 25 to return to the original position.

【0009】 長さの異なるねじを締め付ける場合には、図3に示すように滑動部材22の先 端に、ねじの長さに応じたアジャスタ33を装着する。この時、アジャスタ33 を装着する事により、アジャスタ33を含めた滑動部材22の端面とビット7の 相対距離が変わるためねじの締付深さも変わってしまう。そこで、ねじの長さが かわっても同じ締付深さを得るために、まず図1に示すようにカップリング26 にねじの長さに応じて付された目盛り34を目安として係止部材27を操作し、 滑動部材22のケーシング24内への退入可能長さをアジャスタ33の厚み分変 更し、その後試し締めによって係止部材27を操作し徴調節する。When tightening screws having different lengths, an adjuster 33 corresponding to the length of the screw is attached to the front end of the sliding member 22 as shown in FIG. At this time, by mounting the adjuster 33, the relative distance between the end face of the sliding member 22 including the adjuster 33 and the bit 7 is changed, so that the tightening depth of the screw is also changed. Therefore, in order to obtain the same tightening depth even if the length of the screw is changed, first, as shown in FIG. 1, the locking member 27 is set using the scale 34 attached to the coupling 26 according to the length of the screw as a guide. Is operated to change the retractable length of the sliding member 22 into the casing 24 by the thickness of the adjuster 33, and then the locking member 27 is operated by trial tightening to adjust the length.

【考案の効果】[Effect of device]

本考案によれば、電動機部とねじ締めアタッチメントを連結するカップリング に、締め付けるねじの長さに応じた目盛りを付したので、長さの異なるねじを締 め付けるためにアジャスタを使用しても、前記目盛りを目安として係止部材を操 作する事で、ねじの締付深さのおおよその調節が一度ででき、試し締めの回数を 減らす事ができる。よってアジャスタを使用する際のねじの締付深さの調節に要 する時間が少ないねじ締め機を構成する事ができる。 According to the present invention, the coupling that connects the electric motor section and the screw tightening attachment is graduated according to the length of the screw to be tightened, so even if an adjuster is used to tighten screws of different lengths. By operating the locking member using the scale as a guide, the tightening depth of the screw can be roughly adjusted once, and the number of trial tightening can be reduced. Therefore, it is possible to configure a screw tightener that requires less time to adjust the screw tightening depth when using the adjuster.
