Description
【０００１】[0001]
本考案は例えばジグソー、レシプロソー等の切断機に関するものでありこれら 切断機のブレードの着脱を容易に行い得る切断機のブレード着脱装置に関するも のである。 The present invention relates to a cutting machine such as a jigsaw or a reciprocating saw, and also relates to a blade attaching / detaching device of a cutting machine which can easily attach and detach a blade of these cutting machines.
【０００２】[0002]
従来技術を図２に示す。ケーシング内のモータ（図示せず）によりギヤカバー ２内に設けられたギヤ、クランク機構等の動力伝達手段を介して往復動されるプ ランジャ３下端のブレードホルダ部５に止めねじ２３によってブレード６を取付 けており、該ブレード６の着脱には六角レンチ等の工具２４を使用している。 The prior art is shown in FIG. A blade (6) is fixed to the blade holder (5) at the lower end of the plunger (3) by a set screw (23) which is reciprocated by a motor (not shown) in the casing through a power transmission means such as a gear and a crank mechanism provided in the gear cover (2). The blade 6 is attached, and a tool 24 such as a hexagon wrench is used to attach and detach the blade 6.
【０００３】[0003]
上記したように従来のジグソー等のブレード６の着脱には六角レンチ等の工具 ２４を使用しており、ブレード６が停止する上下方向の位置は定まっておらず、 上死点や下死点で停止するとブレード６の着脱がしずらく、また中間位置で停止 しても力が加わると上死点位置へ移動してしまうというような問題があった。 本考案の目的は上記した従来技術の欠点を解消し、容易に着脱できるようにす ることである。 As described above, a tool 24 such as a hexagon wrench is used to attach / detach the blade 6 such as a conventional jigsaw, and the vertical position at which the blade 6 stops is not fixed. When stopped, the blade 6 is difficult to attach and detach, and even when stopped at the intermediate position, if force is applied, it will move to the top dead center position. An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to enable easy attachment / detachment.

上記目的を達成するために本考案のブレード着脱装置においては、駆動部や伝 達部の動きが遅くなると、固定部と前記駆動部や伝達部間にピンを係合して往復 動するプランジャを機械的に停止させることにより達成される。 In order to achieve the above object, in the blade attaching / detaching device of the present invention, when the movement of the drive unit or the transmission unit becomes slow, a plunger is engaged between the fixed unit and the drive unit or the transmission unit to reciprocate. It is achieved by stopping mechanically.
【０００５】[0005]
上記のように構成されたブレード着脱装置においては、駆動部や伝達部の動き が遅くなるとピンが係合し、プランジャを同じ位置で停止することができ、ブレ ードを着脱しやすい位置に停止させることができる。 In the blade attachment / detachment device configured as described above, when the movement of the drive unit and the transmission unit becomes slow, the pin engages and the plunger can be stopped at the same position, so that the blade can be stopped at a position where it can be easily attached and detached. Can be made.

以下本考案を図示実施例により説明する。図１は本考案着脱装置が採用された 切断機の要部を示すもので、ケーシング１内のモータ（図示せず）によりギヤカ バー２内部に収納されたギヤ７、クランク機構等の動力伝達手段を介してプラン ジャ３がメタル４によって支持され上下に往復運動する。該プランジャ３の下端 に一体的に形成されたブレードホルダ部５にはブレード６が挿入され止めねじ２ ３等によって取付けられる。９はベースで被切断材上を滑動する際の案内板とな る。ギヤ７側面に軸方向の穴８を設け、該穴８に対面する固定壁に設けた案内穴 １０に中間にバネ１１を配してギヤ側にピン１２、反対側にガイド１３を夫々軸 方向移動可能に嵌挿し、右端にストッパ１４を設けた細径の心棒１５をピン１２ に固着すると共にガイド１３の内径部に中ぐり穴１６を設け、該中ぐり穴１６に 前記ストッパ１４を嵌挿しストッパ１４と中ぐり穴１６左端との当接によりピン １２とガイド１３との軸方向分離止めをなす一方、スイッチ１７の右側端面とケ ーシング１間にバネ１８を介してロッド１９を配置し、該ロッド１９と前記ガイ ド１３をフレキシブルワイヤ２０で連結している。なお、前記フレキシブルワイ ヤ２０の代わりにてこを用い、力点にスイッチ１７、作用点にガイド１３、支点 を力点と作用点間の本体１上に設けても良い。 The present invention will be described below with reference to illustrated embodiments. FIG. 1 shows a main part of a cutting machine to which the attachment / detachment device of the present invention is applied. A power transmission means such as a gear 7 and a crank mechanism housed in a gear cover 2 by a motor (not shown) in a casing 1. The plunger 3 is supported by the metal 4 through and reciprocates up and down. A blade 6 is inserted into a blade holder portion 5 formed integrally with the lower end of the plunger 3 and attached by a set screw 23 or the like. Reference numeral 9 is a base which serves as a guide plate when sliding on the material to be cut. An axial hole 8 is provided on the side surface of the gear 7, and a spring 11 is arranged in the middle of a guide hole 10 provided in a fixed wall facing the hole 8 so that a pin 12 is provided on the gear side and a guide 13 is provided on the opposite side. A small-diameter mandrel 15 which is movably fitted and has a stopper 14 at the right end is fixed to the pin 12, and a boring hole 16 is provided in the inner diameter portion of the guide 13. The stopper 14 is fitted and inserted into the boring hole 16. The stopper 14 and the left end of the boring hole 16 stop the pin 12 and the guide 13 from separating in the axial direction, while a rod 19 is arranged between the right end surface of the switch 17 and the casing 1 via a spring 18. The rod 19 and the guide 13 are connected by a flexible wire 20. Instead of the flexible wire 20, a switch 17 may be used as a force point, a guide 13 as an action point, and a fulcrum may be provided on the main body 1 between the force point and the action point.
【０００７】 このような構成において、スイッチ１７のＯＦＦ状態では、バネ１８を圧縮し てロッド１９が押し込まれ、フレキシブルワイヤ２０を介してガイド１３がギヤ ７側へ移動しバネ１１を圧縮してピン１２をギヤ７側面へ押し付ける。従って、 この時、ギヤ７が回転していると、ピン１２の押し付け力、ピン１２と穴８との 隙間等によって決まるある回転数以下において、ピン１２は穴８に挿入されギヤ ７は一定の回転位置で停止し、プランジャ３も一定の上下方向位置で停止する。 スイッチ１７ＯＮの状態では、ロッド１９はバネ１８により左方へ押し出されフ レキシブルワイヤ２０を介してガイド１３が引き出されピン１２のストッパ１４ とガイド１３の中ぐり穴１６左端とが突き当たるからピン１２はギヤ７の穴８よ り引き出されてギヤ７は回転可能状態となる。In such a configuration, when the switch 17 is in the OFF state, the spring 18 is compressed and the rod 19 is pushed in, and the guide 13 is moved to the gear 7 side via the flexible wire 20 to compress the spring 11 and pin it. Press 12 onto the side of gear 7. Therefore, at this time, when the gear 7 is rotating, the pin 12 is inserted into the hole 8 and the gear 7 stays at a constant speed below a certain rotational speed determined by the pressing force of the pin 12 and the clearance between the pin 12 and the hole 8. It stops at the rotational position, and the plunger 3 also stops at a constant vertical position. When the switch 17 is ON, the rod 19 is pushed to the left by the spring 18 and the guide 13 is pulled out through the flexible wire 20 so that the stopper 14 of the pin 12 and the left end of the boring hole 16 of the guide 13 abut. The gear 7 is pulled out from the hole 8 of the gear 7, and the gear 7 becomes rotatable.
