Description
【０００１】[0001]
本考案は被削材を把持する保持具とレシプロソーを組み合わせて構成された保 持具付切断機に関するものである。 The present invention relates to a cutter with a holding tool configured by combining a holding tool for holding a work material and a reciprocating saw.
【０００２】[0002]
従来の保持具付切断機は、図６、図７に示すように、保持具１は鋼管等の被削 材４を保持するためのクランプ手段とレシプロソー２への着脱と、切断時のてこ の支点となるシャフト３からなる。更にクランプ手段は、チェーン５と、該チェ ーン５を係止するためのフック部と、チェーン５を緊締するためのねじ部７から なる。のこ刃８は、周知の如くレシプロソー２の前端部の往復運動する図示しな いプランジャにボルトで固定されている。 As shown in FIGS. 6 and 7, a conventional cutter with a holder has a holder 1 with a clamping means for holding a work material 4 such as a steel pipe and with respect to a reciprocating saw 2, and a lever for cutting. It consists of a shaft 3 that serves as a fulcrum. Further, the clamp means comprises a chain 5, a hook portion for locking the chain 5, and a screw portion 7 for tightening the chain 5. As is well known, the saw blade 8 is fixed by a bolt to a plunger (not shown) that reciprocates at the front end of the reciprocating saw 2.
【０００３】[0003]
従来の保持具付切断機は、レシプロソー２が被削材４の軸と直角にセットされ 、てこの支点となるシャフト３を軸に、被削材４の軸に直角な面内を回動するよ うになっている。しかし、のこ刃８は手持ち工具に要求される重量の制限から、 切断負荷を少なくするため薄くせざるを得ず、なおかつ片持ち固定しかされない ため切断時には図６に示すように曲がりを生じ、結果的に切断面は直角度の悪い 仕上りになってしまうという問題があった。 本考案の目的は、上記問題点を解決し切断面の直角精度の向上を図ることであ る。 In the conventional cutter with a holder, the reciprocating saw 2 is set at right angles to the axis of the work material 4, and is rotated in a plane perpendicular to the shaft of the work material 4 about the shaft 3 serving as a fulcrum of the lever. It is becoming like this. However, the saw blade 8 must be thinned to reduce the cutting load due to the weight limit required for a hand-held tool, and since it is only cantilevered, it bends as shown in Fig. 6 during cutting. As a result, there was a problem that the cut surface had a poor squareness. An object of the present invention is to solve the above problems and improve the right angle accuracy of the cut surface.
【０００４】[0004]
上記目的を達成するために、本考案保持具付切断機では、のこ刃の先端部をガ イドするガイド部材を設けた。該ガイド材を保持具に設ける場合は、一端を保持 具に軸支させて揺動できるようにした棹の他端に装着する。棹は切断中のこ刃の 曲がりを規制できるだけの鋼性を有している。なおガイド部材が装着された棹は 、常にのこ刃の背に追従するようにスプリングで付勢されている。 また先端にガイド部材を装着した棹をレシプロソー本体に取り付けても同様の 目的を達成することが出来る。この場合棹はレシプロソーと一体化されているの で、切断の進行に従ってレシプロソーと同じ動きをするため、前記スプリングで 付勢する必要はない。 In order to achieve the above object, the cutter with holder according to the present invention is provided with a guide member for guiding the tip of the saw blade. When the guide member is provided on the holder, the guide member is attached to the other end of the rod which is pivotally supported by the holder so as to be swingable. The rod is steel enough to control the bending of the saw blade during cutting. The rod to which the guide member is attached is always urged by a spring so as to follow the back of the saw blade. The same purpose can be achieved by attaching a rod having a guide member attached to its tip to the main body of the reciprocating saw. In this case, since the rod is integrated with the reciprocating saw, it moves in the same manner as the reciprocating saw as the cutting progresses, so that it is not necessary to urge it with the spring.
【０００５】[0005]
上記のように構成されたレシプロソーの保持具に追従されたガイド部材は、の こ刃の背の部分をガイドし、切断が進行してもスプリングで付勢されているため 、のこ刃から外れることはない。また棹をレシプロソー本体に取り付けた場合で も、ガイド部材からのこ刃が外れることはない。このようにのこ刃は、取付け部 と先端部の２点で規制されているため曲がることなく、正確に被削材の鋼管の軸 直角面内を通るように動作するため、切断面の直角度は格段に向上する。 The guide member that follows the holder of the reciprocating saw configured as described above guides the back part of the saw blade, and is separated from the saw blade because it is biased by the spring even if cutting progresses. There is no such thing. Even when the rod is attached to the reciprocating saw body, the saw blade does not come off from the guide member. Since the saw blade is regulated at two points, the attachment part and the tip part, it does not bend and operates so as to pass exactly through the plane perpendicular to the axis of the steel pipe of the work material. The angle is dramatically improved.
【０００６】[0006]
本考案の一実施例を図１、図２を用いて説明する。 An embodiment of the present invention will be described with reference to FIGS.
【０００７】 切断機の保持具１はレシプロソー２に対して着脱可能に設けられていると共に 切断時のてこの支点となるシャフト３と、保持具１を被削材４へ緊締するクラン プ手段を形成するチェーン５と、該チェーン５を緊締するためのハンドル６のつ いたねじ部７と、のこ刃８の背をガイドするガイド部材９を装着した棹１０から 構成される。The holder 1 of the cutting machine is detachably attached to the reciprocating saw 2, and includes a shaft 3 serving as a fulcrum of a lever at the time of cutting and a clamping means for tightening the holder 1 to a work material 4. It is composed of a chain 5 to be formed, a threaded portion 7 of a handle 6 for tightening the chain 5, and a rod 10 to which a guide member 9 for guiding the back of a saw blade 8 is attached.
【０００８】 棹１０の一端は保持具１に回動可能に軸支され、スプリング１１によって常に のこ刃８の背に押し付けられている。棹１０の先端部には、のこ刃８の背を挟持 できるように、深い溝を有するローラ状ののこ刃ガイド部材９が保持軸１２を中 心に回動可能に係止されている。のこ刃ガイド部材９は保持軸１２の軸方向に対 して微小な調整が可能なようになっている。One end of the rod 10 is rotatably supported by the holder 1 and is constantly pressed against the spine of the saw blade 8 by a spring 11. A roller-shaped saw blade guide member 9 having a deep groove is rotatably engaged with the holding shaft 12 at the tip of the rod 10 so that the spine of the saw blade 8 can be clamped. . The saw blade guide member 9 can be finely adjusted in the axial direction of the holding shaft 12.
【０００９】 使用に際しては、被削材４の切断位置に保持具１を取付け、ハンドル６を巻く ことによって緊締する。レシプロソー２ののこ刃取付け部１３にのこ刃８を取り 付けてから、保持具１のシャフト３にレシプロソー２を装着する。次にガイド部 材９のついた棹１０を手で引上げ、のこ刃８の背に、ガイド部材９のローラ溝を 嵌め込む。レシプロソー２の電源を入れ切断を開始する。のこ刃８は被削材４か らの反力により曲げられようとするが、ガイド部材９の溝にのこ刃の先端が嵌ま り込んでいるため曲がりを規制される。切断が進行するに従いのこ刃８は下方に 移動するが、スプリング１１によって付勢されているため、ガイド部材９ものこ 刃８に追従して下方に移動する。 次に本考案の他の実施例を図３〜図５を用いて説明する。In use, the holding tool 1 is attached to the cutting position of the work material 4 and the handle 6 is wound to tighten the work piece 4. After attaching the saw blade 8 to the saw blade mounting portion 13 of the reciprocating saw 2, the reciprocating saw 2 is mounted on the shaft 3 of the holder 1. Next, the rod 10 with the guide member 9 is pulled up by hand, and the roller groove of the guide member 9 is fitted into the back of the saw blade 8. Turn on the reciprocating saw 2 to start disconnection. The saw blade 8 tends to be bent by the reaction force from the work material 4, but since the tip of the saw blade is fitted in the groove of the guide member 9, the bending is restricted. The saw blade 8 moves downward as the cutting progresses, but since it is biased by the spring 11, the saw blade 8 of the guide member 9 also moves downward following the saw blade 8. Next, another embodiment of the present invention will be described with reference to FIGS.
【００１０】 先端にガイド部材９を形成した棹１０がレシプロソー２のケーシング１４にボ ルト固定されている。ガイド部材９はのこ刃８の背部を包むように僅かな隙間を 持ってガイドしている。保持具１は上記実施例と同じである。切断にあたっては 、保持具１のシャフト３を軸心にして、レシプロソー２全体が回動しながら被削 材４を切断していくと、棹１０はレシプロソー２と一体に固定されているため、 のこ刃８とガイド部材９の関係は不変であり、のこ刃８の曲がりを防止する。A rod 10 having a guide member 9 formed at its tip is bolted to a casing 14 of the reciprocating saw 2. The guide member 9 guides with a slight gap so as to wrap the back part of the saw blade 8. The holder 1 is the same as in the above embodiment. When cutting, the work piece 4 is cut while the reciprocating saw 2 as a whole rotates while the shaft 3 of the holder 1 is used as an axis, and the rod 10 is fixed integrally with the reciprocating saw 2. The relationship between the saw blade 8 and the guide member 9 is unchanged and prevents the saw blade 8 from bending.
【００１１】[0011]
以上説明したように本考案によれば、のこ刃を片持ち支持ではなく、取付け側 と反対側端部の両方でガイドするガイド部材を、保持具、またはレシプロソー本 体に設けたので、切断時ののこ刃の曲がりを防止することが出来、切断面の精度 を向上させることが出来る。 As described above, according to the present invention, the saw blade is not supported in a cantilever manner, and the guide member that guides the saw blade at both the mounting side and the opposite side end is provided on the holder or the reciprocating saw body. It is possible to prevent the saw blade from bending at the time and improve the accuracy of the cut surface.
