既存の電動工具は、部材の組立を手軽にできるが、ボルトやナットなどの部品を締め付けたり緩めたりする時、部品に応じて夫々作業を行い、一回の作業で多くの部材を組み立てることはできないことから、まず第一部分の作業が行ってから、適当な作業用部材に交換して第二部分の作業を行う必要があるので、異なる作業用部材にいちいち交換しなければならない。例えば、ボルトを締め付ける時は、まず電動工具を用いてボルトを少し締め付けてから、作業用部材をトルクレンチに交換して所定のトルクでしっかりと締め付ける。故に、作業を行う時には、部品の規格や種類に応じて適当な作業用部材と何度も交換しなければならないことから、作業に時間がかかるといった問題があった。   Existing power tools can easily assemble parts, but when tightening or loosening parts such as bolts and nuts, work according to the parts, and it is not possible to assemble many parts in one operation Since it is impossible, it is necessary to replace the work part first with the appropriate work member and then the second part work. Therefore, the work must be replaced with a different work member. For example, when tightening a bolt, first tighten the bolt a little using an electric tool, then replace the working member with a torque wrench and tighten firmly with a predetermined torque. Therefore, when the work is performed, there is a problem that the work takes time because it is necessary to replace the work member with an appropriate work member many times according to the standard and type of the parts.

Opening 22 is formed.

前記ローター３０、第一作業部材４０、および第二作業部材５０は、工具本体２０の組立空間２１に設置され、そのうち、該ローター３０には、互いに対向する位置に第一駆動端３１と第二駆動端３２が設けられる。尚、本実施例におけるローター３０は、気体駆動型でもよく、電動駆動型でもよい。   The rotor 30, the first working member 40, and the second working member 50 are installed in the assembly space 21 of the tool body 20, and the rotor 30 has a first driving end 31 and a second working member at positions facing each other. A drive end 32 is provided. The rotor 30 in this embodiment may be a gas drive type or an electric drive type.

前記第一作業部材４０は、第一駆動端３１に組み合わせられると共に、第一減速機構４１と、第二減速機構４２と、第一伝動軸４３を備え、そのうち、該第一減速機構４１は、ローター３０の第一駆動端３１に取り付けられると共に、連結部４１１を備え、該第二減速機構４２は、第一減速機構４１の連結部４１１に取り付けられると共に、連接筒部４２１を備え、該第一伝動軸４３は、着脱可能に連接筒部４２１に取り付けられると共に、工具本体２０の一方の開口２２から突出する。尚、前記第一作業部材４０には、第一減速機構４１及び第二減速機構４２が設置されていなくてもよく、また、第一伝動軸４３は第一駆動端３１に取り付けられてもよい。   The first working member 40 is combined with the first drive end 31 and includes a first reduction mechanism 41, a second reduction mechanism 42, and a first transmission shaft 43, of which the first reduction mechanism 41 is The second reduction mechanism 42 is attached to the first drive end 31 of the rotor 30 and includes a connecting portion 411. The second reduction mechanism 42 is attached to the connection portion 411 of the first reduction mechanism 41 and includes a connecting cylinder portion 421. The one transmission shaft 43 is detachably attached to the connecting cylinder portion 421 and protrudes from one opening 22 of the tool body 20. The first working member 40 may not be provided with the first reduction mechanism 41 and the second reduction mechanism 42, and the first transmission shaft 43 may be attached to the first drive end 31. .

図７及び図８に示すように、前記第二作業部材５０は、第二駆動端３２に取り付けられると共に、一方向打撃機構５１及び第二伝動軸５２を備え、そのうち、一方向打撃機構５１は、ローター３０の第二駆動端３２に取り付けられると共に、連接管部５１１を備え、該第二伝動軸５２は、工具本体２０の他方の開口２２から突出するように、着脱可能に一方向打撃機構５１の連接管部５１１に取り付けられる。   As shown in FIGS. 7 and 8, the second working member 50 is attached to the second drive end 32 and includes a one-way striking mechanism 51 and a second transmission shaft 52, of which the one-way striking mechanism 51 is The unidirectional striking mechanism is attached to the second drive end 32 of the rotor 30 and includes a connecting pipe portion 511, and the second transmission shaft 52 is detachable so as to protrude from the other opening 22 of the tool body 20. It is attached to 51 connecting pipe portions 511.

前記第一作業部材４０を使用する時は、手で柄部１１を握持しながら、第一伝動軸４３と対応するようにスイッチ１３によりカバーリング１２を回転させる。この時、スイッチ１３によりローター３０が回転し、第一減速機構４１及び第二減速機構４２によりローター３０の回転速度を減速してトルクを大きく出力することから、第一伝動軸４３によりボルトを締め付けたり緩めたりすることができる。   When the first working member 40 is used, the cover ring 12 is rotated by the switch 13 so as to correspond to the first transmission shaft 43 while holding the handle portion 11 by hand. At this time, the rotor 30 is rotated by the switch 13, and the rotation speed of the rotor 30 is reduced by the first reduction mechanism 41 and the second reduction mechanism 42 to output a large torque, so that the bolt is tightened by the first transmission shaft 43. Or loosen.

一方、前記第二作業部材５０を使用する時は、手で柄部１１を握持しながら、第二伝動軸５２を連接管部５１１に取り付けると共に、該第二伝動軸５２と対応するようにスイッチ１３によりカバーリング１２を回転させる。尚、安全性を考慮すると、第二減速機構４２を連接筒部４２１から取り外してもよい。そして、スイッチ１３の操作によりローター３０が回転すると、一方向打撃機構５１が、ローター３０のパワーを第二伝動軸５２に伝えると共に、その一方向打撃機構５１の打撃力により第二伝動軸５２に伝えるパワーを増強する。この構成によれば、第二伝動軸５２を用いてボルトを固く締めたり、固く締めているナットを緩めたりすることができる。   On the other hand, when the second working member 50 is used, the second transmission shaft 52 is attached to the connecting pipe portion 511 while the handle portion 11 is gripped by hand, and the second transmission shaft 52 corresponds to the second transmission shaft 52. The cover ring 12 is rotated by the switch 13. In consideration of safety, the second reduction mechanism 42 may be removed from the connecting cylinder portion 421. When the rotor 30 is rotated by the operation of the switch 13, the one-way striking mechanism 51 transmits the power of the rotor 30 to the second transmission shaft 52, and the striking force of the one-way striking mechanism 51 applies the second transmission shaft 52 to the second transmission shaft 52. Strengthen the power to convey. According to this structure, the bolt can be tightened using the second transmission shaft 52, or the nut can be loosened.

本発明に係るダブルヘッド型電動工具は、上述した構造を有し、即ち、作業用部材の交換が不要であることから、例えば、自動車のタイヤに用いるボルトやナットなどを締め付けたり緩めたりすることができ、一度に作業を完了できるので、作業時間や手間を省くことができると共に、作業用部材の数量も少なくなる。   The double-head power tool according to the present invention has the above-described structure, that is, it is not necessary to replace the working member. Since work can be completed at one time, work time and labor can be saved, and the number of work members is reduced.
