耗させて寿命の低下を招いていた。 However, in the conventional screw tightening machine, the clutch is engaged with the motor at full speed, so even if the power is transmitted stepwise using an intermediate clutch, a collision with a large speed difference occurs at any stage between the clutches. The noise is generated and the operability is deteriorated, and the cam ridge is worn and the life is shortened.

上記課題を解決するために本発明は、モータと、先端工具を保持可能な先端工具保持部と、前記モータの回転が伝達される駆動部と、該先端工具保持部に接続され、該駆動部の係合部と係合可能な被係合部を有する回転可能な従動部とを有し、前記先端工具保持部は前記回転軸方向に移動可能であり、第１の位置では前記係合部と前記被係合部は係合せず、第２の位置では前記係合部と前記被係合部とが係合する動力工具であって、前記係合部又は前記被係合部のいずれかは、円錐状の凹部又は円錐状の凸部を有していることを特徴とする。   In order to solve the above-described problems, the present invention provides a motor, a tip tool holding portion capable of holding a tip tool, a driving portion to which rotation of the motor is transmitted, and the driving portion connected to the tip tool holding portion. A rotatable driven portion having an engaged portion engageable with the engaging portion, the tip tool holding portion being movable in the direction of the rotation axis, and in the first position, the engaging portion And the engaged portion are not engaged, and in the second position, the engaging portion and the engaged portion are engaged with each other, and the power tool is either the engaging portion or the engaged portion. Has a conical concave portion or a conical convex portion.

回転する係合部及び係合部により回転を伝達される被係合部を、円錐状の凸部及び円錐状の凹部とにより構成することにより、係合部及び被係合部の回転の伝達による騒音を抑制しながら、回転の伝達効率を高めることができる。   The rotation of the engaging portion and the engaged portion is transmitted by configuring the rotating engaging portion and the engaged portion to which the rotation is transmitted by the engaging portion by a conical convex portion and a conical concave portion. The transmission efficiency of the rotation can be increased while suppressing the noise caused by.

図１に、本発明の動力工具の第１の実施形態を示す。本発明の動力工具の例として、電動のねじ締め機を例に説明する。   FIG. 1 shows a first embodiment of a power tool of the present invention. As an example of the power tool of the present invention, an electric screw tightener will be described as an example.

図１に、ねじ締め機１を示す。ねじ締め機１は、ハウジング２にその表面を覆われている。ハウジング２は、モータ３を覆うモータハウジング２Ａ、Ｄ型の形状をしておりその一部が作業者が把持するハンドルとなるハンドルハウジング２Ｃ及びクラッチハウジング２Ｂにより構成される。ハンドルハウジング２Ｃはモータハウジング２Ａの後方に設けられており、クラッチハウジング２Ｂはモータハウジング２Ａの前方に設けられている。   FIG. 1 shows a screw tightening machine 1. The surface of the screw tightening machine 1 is covered with a housing 2. The housing 2 is composed of a motor housing 2A that covers the motor 3 and a handle housing 2C and a clutch housing 2B. The handle housing 2C is provided behind the motor housing 2A, and the clutch housing 2B is provided in front of the motor housing 2A.

ハンドルハウジングのＤ型の形状の内周面には、トリガ５が設けられている。また、ハンドルハウジング３Ｃの下部には、電源コード４が設けられている。   A trigger 5 is provided on the inner peripheral surface of the D-shaped shape of the handle housing. A power cord 4 is provided below the handle housing 3C.

モータ３は、ハウジング２に回転可能に保持されており、その前方には、モータ３の回転軸に設けられる歯車であるピニオン３Ａが設けられている。ピニオン３Ａと噛合するように、ギヤ６Ａが設けられており、ギヤ６Ａは駆動部材６に圧入されている。駆動部材６には、その中心に空洞が設けられており、先端工具保持部８と一体のシャフト８Ａが挿入されている。シャフト８Ａには、従動部材７が圧入されている。先端工具保持部８は、クラッチハウジング２Ｂに回転可能に、メタル１１により保持されている。   The motor 3 is rotatably held by the housing 2, and a pinion 3 </ b> A that is a gear provided on the rotation shaft of the motor 3 is provided in front of the motor 3. A gear 6A is provided so as to mesh with the pinion 3A, and the gear 6A is press-fitted into the drive member 6. The driving member 6 is provided with a cavity at the center thereof, and a shaft 8A integrated with the tip tool holding portion 8 is inserted therein. The driven member 7 is press-fitted into the shaft 8A. The tip tool holding portion 8 is held by a metal 11 so as to be rotatable on the clutch housing 2B.

先端工具保持部８には、先端工具９がボール８Ｂによって保持されている。   The tip tool 9 is held by the ball 8B in the tip tool holding portion 8.

駆動部材６は、その前方に円錐状の凸部６Ｓが設けられている。また、従動部材７には、その後方に円錐状の凹部７Ｓが設けられている。   The drive member 6 is provided with a conical convex portion 6S in front thereof. The driven member 7 is provided with a conical recess 7S behind the driven member 7.

図２を用いて、ねじ締め機１の動作について説明する。   The operation of the screw tightening machine 1 will be described with reference to FIG.

先端工具９を、ねじ１００と係合させた状態で、作業者が電源コード４に給電した状態でトリガ５を操作すると、モータ３へと給電される。給電により、モータ３は回転する。この回転により、ピニオン３Ａが回転する。ピニオン３Ａは、ギヤ６Ａと噛み合っているので、ギヤ６Ａに回転が伝達される。ギヤ６Ａは、駆動部材６が回転する。   When the operator operates the trigger 5 while the tip tool 9 is engaged with the screw 100 and the power cord 4 is powered, the motor 3 is powered. The motor 3 is rotated by the power supply. By this rotation, the pinion 3A rotates. Since the pinion 3A meshes with the gear 6A, rotation is transmitted to the gear 6A. The drive member 6 rotates in the gear 6A.

ねじ１００を壁に押し付けると、先端工具保持部８が後方へと移動する。先端工具保持部８と一体に設けられているシャフト８Ａも同時に後方へと移動する。シャフト８Ａに圧入された従動部材７も同時に後方へと移動する。   When the screw 100 is pressed against the wall, the tip tool holding portion 8 moves backward. The shaft 8A provided integrally with the tip tool holding portion 8 also moves backward simultaneously. The driven member 7 press-fitted into the shaft 8A also moves backward simultaneously.

このように、従動部材７が後方へと移動することにより、駆動部材６の円錐状の凸部６Ｓは、従動部材７の円錐状の凹部７Ｓと接触し、係合する。駆動部材６の円錐状の凸部６Ｓは、従動部材７の円錐状の凹部７Ｓと係合すると、駆動部材６から従動部材７へと回転が伝達される。ここで、駆動部材６及び従動部材７との係合が、円錐状の凸部及び円錐状の凹部によって成されるために、摩擦による伝達をより大きくすることができるようになっている。   Thus, when the driven member 7 moves rearward, the conical convex portion 6S of the driving member 6 comes into contact with and engages with the conical concave portion 7S of the driven member 7. When the conical convex portion 6 </ b> S of the driving member 6 is engaged with the conical concave portion 7 </ b> S of the driven member 7, rotation is transmitted from the driving member 6 to the driven member 7. Here, since the engagement with the drive member 6 and the driven member 7 is formed by the conical convex portion and the conical concave portion, transmission by friction can be further increased.

なお、ねじ１００を壁に留め終わる際には、ストッパ１０が壁と当接することにより、ねじ１００に先端工具９から回転力が伝達されなくなる。   When the screw 100 is fixed to the wall, the stopper 10 comes into contact with the wall, so that the rotational force is not transmitted to the screw 100 from the tip tool 9.

以上、本発明の実施例においては、駆動部材に円錐状の凸部、従動部材に円錐状の凹部を設ける構成としたが、駆動部材に円錐状の凹部、従動部材に円錐状の凸部を設ける構成であっても、本発明の効果を奏し得ることができる。また、本発明の実施例においては、一つの駆動部材及び一つの従動部材に円錐状の凸部及び円錐状の凹部を設ける構成としたが、多数の駆動部材及び従動部材を設ける構成であっても、本発明の効果を奏し得ることができる。   As described above, in the embodiment of the present invention, the drive member has the conical convex portion and the driven member has the conical concave portion. However, the drive member has the conical concave portion and the driven member has the conical convex portion. Even if it is the structure provided, the effect of this invention can be show | played. In the embodiment of the present invention, a conical convex portion and a conical concave portion are provided on one driving member and one driven member, but a configuration in which a large number of driving members and driven members are provided. Also, the effects of the present invention can be achieved.
