Description

本発明は、トルク調整ダイヤルを回動させることによってトルク調整を行うことができるドライバドリル等の電動工具に関するものである。   The present invention relates to a power tool such as a driver drill that can perform torque adjustment by rotating a torque adjustment dial.

例えば、ドライバドリルは、ハウジングに内蔵されたモータの回転トルクをトルク調整機構を介して先端工具に伝達し、該先端工具を所定の速度で回転駆動してネジ締め等の作業を行うものであって、その構成を図３に示す。   For example, a driver drill transmits torque of a motor built in a housing to a tip tool via a torque adjustment mechanism, and rotates the tip tool at a predetermined speed to perform operations such as screw tightening. The configuration is shown in FIG.

即ち、図３は従来のドライバドリル要部の側断面図であり、図示のドライバドリル１’は、ハウジング２の胴体部２Ａ内に駆動源としてのモータ３を収容しており、該モータ３の出力軸（モータ軸）３ａの回転は遊星ギヤ減速機構４によって減速されてスピンドル５に伝達され、該スピンドル５の先端部にチャック６によって装着されたドライバビット７が所定の速度で回転駆動されてネジ締め等の作業が行われる。この場合、ドライバビット７に伝達されるトルクはトルク調整機構８によって調整される。   That is, FIG. 3 is a side sectional view of a main part of a conventional driver drill. The illustrated driver drill 1 ′ accommodates a motor 3 as a drive source in a body portion 2 </ b> A of a housing 2. The rotation of the output shaft (motor shaft) 3a is decelerated by the planetary gear reduction mechanism 4 and transmitted to the spindle 5, and the driver bit 7 attached to the tip of the spindle 5 by the chuck 6 is rotated at a predetermined speed. Work such as screw tightening is performed. In this case, the torque transmitted to the driver bit 7 is adjusted by the torque adjustment mechanism 8.

ところで、前記遊星ギヤ減速機構４は、２段又は３段減速が選択可能であって、最終段のインターナルギヤ（リングギヤ）９は選択的に回転可能であって、これが固定されるとモータ３の回転がスピンドル５に伝達され、該インターナルギヤ９の固定が解除されて回転するとスピンドル５への回転伝達が遮断され、スピンドル５への伝達トルク（最大値）はトルク調整機構８によって調整される。   By the way, the planetary gear reduction mechanism 4 can select two-stage or three-stage reduction, and the internal gear (ring gear) 9 of the final stage can be selectively rotated. When this is fixed, the motor 3 Is transmitted to the spindle 5, and when the internal gear 9 is unlocked and rotated, the rotation transmission to the spindle 5 is cut off, and the torque (maximum value) transmitted to the spindle 5 is adjusted by the torque adjustment mechanism 8. The

ここで、トルク調整機構８によるトルク調整は、ハウジング２の胴体部２Ａの先端に回転可能に設けられた円筒状のトルク調整ダイヤル１０を回すことによってなされる。   Here, the torque adjustment by the torque adjustment mechanism 8 is performed by turning a cylindrical torque adjustment dial 10 that is rotatably provided at the front end of the body portion 2A of the housing 2.

即ち、スピンドル５の外周には円筒状のネジ部材１１が固設されており、このネジ部材１１の外周にはバネ受け１２が前後方向（図３の右方を前方とする）に移動可能に螺合している。そして、このバネ受け１２の外周は前記トルク調整ダイヤル１０の内周にスプライン嵌合しており、バネ受け１２は、トルク調整ダイヤル１０と共に回転してネジ部材１１に沿って前後方向に移動する。   That is, a cylindrical screw member 11 is fixed on the outer periphery of the spindle 5, and a spring receiver 12 is movable on the outer periphery of the screw member 11 in the front-rear direction (the right side in FIG. 3 is the front). It is screwed. The outer periphery of the spring receiver 12 is splined to the inner periphery of the torque adjustment dial 10, and the spring receiver 12 rotates with the torque adjustment dial 10 and moves in the front-rear direction along the screw member 11.

他方、遊星ギヤ減速機構４の前記インターナルギヤ９の前端面には複数のボール１３が凹凸係合しており、ボール１３にはバネ受け１４が当接しており、このバネ受け１４と前記バネ受け１２間にはコイルバネ１５が縮装されている。従って、ボール１３はコイルバネ１５によってインターナルギヤ９の前端面に押圧されており、その押圧力（つまり、最大伝達トルク）は、トルク調整ダイヤル１０を回してバネ受け１２を前後動させてコイルバネ１５の長さ（バネ力）を変えることによって調整される。   On the other hand, a plurality of balls 13 are engaged with the front end surface of the internal gear 9 of the planetary gear speed reduction mechanism 4, and a spring receiver 14 is in contact with the balls 13. The spring receiver 14 and the spring A coil spring 15 is fitted between the receptacles 12. Therefore, the ball 13 is pressed against the front end face of the internal gear 9 by the coil spring 15, and the pressing force (that is, the maximum transmission torque) is rotated by rotating the torque adjustment dial 10 to move the spring receiver 12 back and forth, thereby causing the coil spring 15 to move. It is adjusted by changing the length (spring force).

即ち、ドライバビット７側からの負荷が大きくなって伝達トルクが所定値を超えると、コイルバネ１５によってボール１３に与えられる押圧力によってはインターナルギヤ９を固定することができず、インターナルギヤ９がコイルバネ１５の付勢力に抗して乗り越えて回転するため、回転がスピンドル５に伝達されず、ドライバビット７に伝達される最大伝達トルクがそのときのコイルバネ１５のバネ力によって決定される値に設定される。そして、この状態からトルク調整ダイヤル１０を回してバネ受け１２を後退させ、コイルバネ１５を押し縮めて該コイルバネ１５のバネ力を大きくすれば、ボール１３のインターナルギヤ９への押圧力も大きくなってスピンドル５への最大伝達トルクが高められる。又、トルク調整ダイヤル１０を逆に回してバネ受け１２を前進させ、コイルバネ１５を伸ばして該コイルバネ１５のバネ力を小さくすれば、ボール１３のインターナルギヤ９への押圧力も小さくなってスピンドル５への最大伝達トルクが下げられる。   That is, when the load from the driver bit 7 side increases and the transmission torque exceeds a predetermined value, the internal gear 9 cannot be fixed by the pressing force applied to the ball 13 by the coil spring 15, and the internal gear 9 Is rotated over the urging force of the coil spring 15 so that the rotation is not transmitted to the spindle 5 and the maximum transmission torque transmitted to the driver bit 7 is determined by the spring force of the coil spring 15 at that time. Is set. When the torque adjustment dial 10 is turned from this state to retract the spring receiver 12 and the coil spring 15 is pressed and contracted to increase the spring force of the coil spring 15, the pressing force of the ball 13 to the internal gear 9 also increases. Thus, the maximum transmission torque to the spindle 5 is increased. Further, if the torque adjustment dial 10 is turned in the reverse direction to advance the spring receiver 12 and the coil spring 15 is extended to reduce the spring force of the coil spring 15, the pressing force of the ball 13 to the internal gear 9 is also reduced. The maximum transmission torque to 5 is reduced.

以上のようにトルク調整ダイヤル１０を回すことによって伝達トルクが調整されるが、図４の展開図に示すように、トルク調整ダイヤル１０の外周面にはトルクの大きさを表示する「１」，「５」，「９」…の数字が表示されており、作業者はこの数字を見ながらトルク調整ダイヤル１０を回してトルク調整を容易に行うことができる。   As described above, the transmission torque is adjusted by turning the torque adjustment dial 10. As shown in the development view of FIG. 4, “1”, which indicates the magnitude of the torque, is displayed on the outer peripheral surface of the torque adjustment dial 10. Numbers “5”, “9”... Are displayed, and the operator can easily adjust the torque by turning the torque adjustment dial 10 while viewing the numbers.

他方、図３に示すように、ハウジング２の胴体部２Ａからはハンドル部２Ｂが略直角に延びており、このハンドル部２Ｂの上部前面にはスイッチ１６が設けられ、その上方にはＬＥＤライト１７が設けられている。尚、図示しないが、ハンドル部２Ｂの下端には充電可能なバッテリが着脱可能に装着されている。   On the other hand, as shown in FIG. 3, a handle portion 2B extends from the body portion 2A of the housing 2 at a substantially right angle, a switch 16 is provided on the upper front surface of the handle portion 2B, and an LED light 17 is provided above it. Is provided. Although not shown, a rechargeable battery is detachably attached to the lower end of the handle portion 2B.

而して、作業者が当該ドライバドリル１のハンドル部２Ｂを把持してスイッチ１６をＯＮ操作すると、不図示のバッテリからモータ３に給電されて該モータ３が起動され、スピンドル５及びこれに装着されたドライバビット７が回転駆動されるとともに、ＬＥＤライト１７にも給電されて該ＬＥＤライト１７が点灯し、ドライバビット７の先端部がスポット的に照明される。   Thus, when the operator grips the handle portion 2B of the driver drill 1 and turns on the switch 16, the motor 3 is powered from a battery (not shown) to start the motor 3, and the spindle 5 and the spindle 5 are mounted on the motor 3 The driven driver bit 7 is driven to rotate, the LED light 17 is also supplied with power, the LED light 17 is turned on, and the tip of the driver bit 7 is illuminated in a spot manner.

ところで、特許文献１には、本体ハウジングの前方下面に設けられたＬＥＤランプの光の一部を本体ハウジングの前方上面に設けられた表示窓に光ファイバによって伝送し、該表示窓を照明するようにした電動工具が提案されている。
特開２００２−３０１６６９号公報 By the way, in Patent Document 1, a part of the light of the LED lamp provided on the front lower surface of the main body housing is transmitted to the display window provided on the front upper surface of the main body housing by an optical fiber to illuminate the display window. An electric tool is proposed.

本発明によれば、透明なトルク調整ダイヤルに光源からの光を照射して該トルク調整ダイヤル全体を発光させるようにしたため、トルク調整ダイヤルの外周面に表示されたトルク設定値を暗所においてもはっきりと視認することができ、簡単な構成で暗所でもトルク調整を容易且つ正確に行うことができる。   According to the present invention, the transparent torque adjustment dial is irradiated with light from the light source so that the entire torque adjustment dial emits light. Therefore, the torque setting value displayed on the outer peripheral surface of the torque adjustment dial can be set even in the dark. It can be clearly recognized, and torque adjustment can be easily and accurately performed in a dark place with a simple configuration.

以下に本発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

Therefore, in FIGS. 1 and 2, the same elements as those shown in FIGS. 3 and 4 are denoted by the same reference numerals, and only the characteristic configuration and operation of the present invention will be described below.

本実施の形態においては、トルク調整ダイヤル１０が透明樹脂で構成されており、その外周面には、図２に示すように、トルクの大きさ（トルク設定値）を表示する「１」，「５」，「９」…の数字が表示されている。具体的には、図２に示すように、トルク調整ダイヤル１０の外周面には鋸刃状の表示部１０ａ（ハッチングを付した部分）には塗装が施されて不透明となっており、この表示部１０ａにトルクの大きさ（トルク設定値）を表示する「１」，「５」，「９」…の数字が表示されている。そして、このトルク調整ダイヤル１０の外周面の表示部１０ａを除く部分が透明部１０ｂとなっており、この透明部１０ｂを光が透過することができる。   In the present embodiment, the torque adjustment dial 10 is made of transparent resin, and “1”, “1”, which displays the magnitude of the torque (torque setting value), as shown in FIG. Numbers “5”, “9”... Are displayed. Specifically, as shown in FIG. 2, the outer peripheral surface of the torque adjustment dial 10 is coated with a saw blade-like display portion 10 a (a hatched portion) to make it opaque. Numbers “1”, “5”, “9”,... For displaying the magnitude of torque (torque setting value) are displayed on the part 10a. And the part except the display part 10a of the outer peripheral surface of this torque adjustment dial 10 is the transparent part 10b, and light can permeate | transmit the transparent part 10b.

又、本実施の形態に係るドライバドリル１においては、図１に示すように、ハウジング５内のトルク調整ダイヤル１０の後端面に接する部位の上下にはＬＥＤライト１７がそれぞれ配設されており、これらのＬＥＤライト１７はリード線１８及びスイッチ１６を介して不図示のバッテリに電気的に接続されている。尚、図示しないが、ＬＥＤライト１７の後方には反射板が設けられている。   Further, in the driver drill 1 according to the present embodiment, as shown in FIG. 1, LED lights 17 are respectively disposed above and below the portion of the housing 5 that contacts the rear end surface of the torque adjustment dial 10.
