Description

卓上切断工具Desktop cutting tool
　この発明は、テーブル上に載置した切断材を切断加工する卓上切断工具に関する。 This invention relates to a tabletop cutting tool for cutting a cutting material placed on a table.
　この種の切断工具では、テーブル上に切断材を位置決めするための位置決めフェンスが備え付けられている。この位置決めフェンスの位置決め面に切断材を当接させて当該切断材のテーブル上の位置決めがなされる。多くの場合、この位置決めフェンスは、切断刃に対して左右に配置されており、安定した切断加工を実現するために切断刃（切断部位）に極力近い範囲にまで位置決め面を配置するための改良が加えられている。 This type of cutting tool is equipped with a positioning fence for positioning the cutting material on the table. The cutting material is brought into contact with the positioning surface of the positioning fence to position the cutting material on the table. In many cases, this positioning fence is arranged on the left and right with respect to the cutting blade, and in order to realize stable cutting processing, the positioning surface is improved so that it is as close as possible to the cutting blade (cutting site). Has been added.
　一方、この種の切断工具には、工具本体部を左方または右方へ傾斜させて切断刃を切断材に対して斜めに切り込んで行う傾斜切りを可能とし、あるいはテーブルを左方又は右方に回転させて切断刃を平面的に見て斜めに切り込ませる斜め切りを可能とする機能を備えている。この傾斜切り等を行う際には、切断刃が使用者から見て左側若しくは右側に傾いて位置決めフェンスに対する相対位置が変化する。このため、従来位置決めフェンスには、切断刃との干渉を回避するため位置決め面の一部を可動式にして切断刃から離間する方向に退避可能としたものが提供されている。係る可動式の位置決めフェンスに関する従来の技術が下記の特許文献に記載されている。 On the other hand, for this type of cutting tool, it is possible to perform inclined cutting by inclining the tool body part to the left or right and cutting the cutting blade obliquely with respect to the cutting material, or the table to the left or right It is provided with a function that makes it possible to perform an oblique cutting that is rotated obliquely and cut obliquely when viewed in plan view. When performing this inclination cutting etc., a cutting blade inclines to the left or the right side seeing from a user, and the relative position with respect to a positioning fence changes. For this reason, in order to avoid interference with the cutting blade, a conventional positioning fence is provided in which a part of the positioning surface is movable and can be retracted in a direction away from the cutting blade. Conventional techniques relating to such a movable positioning fence are described in the following patent documents.
　特許文献１（特開２００９－２５５２７３号公報）には、位置決め面の一部を左右方向にスライドさせて退避可能とした技術が開示されている。特許文献２（特開２００６－１６７８８５号公報）、特許文献３（特開平９－１０３９１３号公報）には、位置決め面の一部を上下に回転させて退避可能とした技術が開示されている。特許文献４（米国特許第５７５５１４８号明細書）には位置決め面の一部をスライド式とし、係るスライド受け面にさらに回転式の位置決め面を設けた技術が開示されている。 Japanese Patent Application Laid-Open No. 2009-255273 discloses a technique in which a part of a positioning surface can be slid in the left-right direction to be retracted. Patent Document 2 (Japanese Patent Laid-Open No. 2006-167885) and Patent Document 3 (Japanese Patent Laid-Open No. 9-103913) disclose a technique in which a part of a positioning surface can be rotated up and down to be retracted. Patent Document 4 (US Pat. No. 5,755,148) discloses a technique in which a part of a positioning surface is a slide type, and a rotary positioning surface is further provided on the slide receiving surface.
　これら従来の技術によれば、切断刃を傾斜させた傾斜切り時等には位置決め面の一部を切断刃に干渉しない位置まで退避可能とすることにより、切断刃を直角に位置させた直角切り時には位置決め面を極力切断刃に接近させて位置させることでより安定した切断加工を行うことができるようになっていた。 According to these conventional techniques, when the cutting blade is inclined, for example, the cutting blade is positioned at a right angle by allowing a part of the positioning surface to be retracted to a position where it does not interfere with the cutting blade. Sometimes, the positioning surface can be positioned as close to the cutting blade as possible to perform more stable cutting.
　しかしながら、切断刃を直角に位置させた直角切り時について、位置決めフェンスの位置決め面をより一層接近させたいとの要望があり、この要望を実現するためには従来の位置決め面の退避構造では退避量が不十分で切断刃の十分な傾斜角度に対応できない問題があった。 However, there is a desire to make the positioning surface of the positioning fence even closer when cutting at right angles with the cutting blade positioned at right angles. However, there was a problem that it was not possible to cope with a sufficient inclination angle of the cutting blade.
　本発明は、係る従来の問題を解消するためになされたもので、位置決めフェンスの位置決め面について直角切り時においてより切断刃に接近させることができる一方、傾斜切り時等には従来よりも大きな退避量で位置決め面の一部若しくは全体を退避させることができるようにすることを目的とする。 The present invention has been made to solve the conventional problems, and the positioning surface of the positioning fence can be brought closer to the cutting blade when cutting at right angles, while it is retracted larger than before when tilting cutting. It is an object to enable a part or the whole of a positioning surface to be retracted by an amount.
　上記の課題は以下の各発明により解決される。本願発明は、切断材を載置するテーブルと、テーブルに支持された工具本体部と、テーブルに載置した切断材を当接させてテーブル面方向に位置決めする位置決めフェンスを備えた卓上切断工具である。本願発明では、位置決めフェンスは、基台部と、基台部に対してそれぞれ移動可能な第１及び第２可動フェンスを備えている。本願発明では、基台部と第１可動フェンスと第２可動フェンスの少なくとも一つに切断材を当接させてテーブル面方向に位置決めするための位置決め面を備えている。本願発明では、第１可動フェンスは、第２可動フェンスの移動とは独立して回動可能となっている。 The above problems are solved by the following inventions. The present invention is a tabletop cutting tool provided with a table for placing a cutting material, a tool main body supported by the table, and a positioning fence for positioning the cutting material placed on the table in contact with the table surface. is there. In this invention, the positioning fence is provided with the 1st and 2nd movable fence which can each be moved with respect to a base part and a base part.

　次に、工具本体部１０を支持する揺動支持部４５の前面には、夜間や暗所での切断作業の便宜を図るために切断部位を明るく照らすための照明装置６０が装備されている。この照明装置６０の詳細が図２０に示されている。この照明装置６０は、図３に示すように揺動支持部４５の右側前面であって、正面視で回転刃具１２よりも右側に取り付けられている。また、この照明装置６０は、工具本体部１０の揺動支点（揺動支軸４７）よりも下側に配置されている。この照明装置６０により、切断部位（刃先）が明るく照らされる。 Next, an illuminating device 60 for brightly illuminating the cutting site is equipped on the front surface of the swinging support portion 45 that supports the tool body portion 10 in order to facilitate cutting work at night or in a dark place. Details of the illumination device 60 are shown in FIG. As shown in FIG. 3, the illuminating device 60 is attached to the right front surface of the swing support portion 45 and to the right of the rotary blade 12 in a front view. The illumination device 60 is disposed below the swing fulcrum (swing support shaft 47) of the tool body 10. By this illuminating device 60, the cutting part (blade edge) is illuminated brightly.
　図２０に示すようにこの照明装置６０は、３つのＬＥＤ６２～６２（発光ダイオード）を光源としている。３つのＬＥＤ６２～６２は、制御基板６１に搭載されている。３つのＬＥＤ６２～６２は同一円周上の三等分位置に配置されている。しかも、３つのＬＥＤ６２～６２は、その照射方向を相互に平行とする向き（姿勢）で相互に接近して配置されている。 As shown in FIG. 20, the illumination device 60 uses three LEDs 62 to 62 (light emitting diodes) as light sources. The three LEDs 62 to 62 are mounted on the control board 61. The three LEDs 62 to 62 are arranged at three equal positions on the same circumference. Moreover, the three LEDs 62 to 62 are arranged close to each other in a direction (attitude) in which the irradiation directions are parallel to each other.
　３つのＬＥＤ６２～６２は、照明ケース６３内に収容されている。照明ケース６３の前部には透明カバー６４が取り付けられている。透明カバー６４は、まっすぐ前側（使用者側）に向けられている。但し、透明カバー６４は、やや下方へ向けられている。 The three LEDs 62 to 62 are accommodated in the lighting case 63. A transparent cover 64 is attached to the front portion of the lighting case 63. The transparent cover 64 is directed straight to the front side (user side). However, the transparent cover 64 is directed slightly downward.
　図２０に示すように３つのＬＥＤ６２～６２の照射方向は、側面視で下向きに傾斜した方向とされている。また、３つのＬＥＤ６２～６２の照射方向は、平面視で左側へ傾斜した方向とされている。このため、図２０において（右側面視で）、制御基板６１の裏面が見えている。 As shown in FIG. 20, the irradiation directions of the three LEDs 62 to 62 are inclined downward in a side view. The irradiation direction of the three LEDs 62 to 62 is inclined to the left in plan view. For this reason, the rear surface of the control board 61 is visible in FIG.
　このように、正面視で回転刃具１２に対して右側にオフセットした位置に照明装置６０が取り付けられ、３つのＬＥＤ６２～６２がその照射方向を側面視で下向きかつ平面視で左側に傾斜した向きとする姿勢で照明ケース６３内に収容されていることにより、回転刃具１２の刃先（切断部位）が効率よく照らされるようになっている。本実施形態では、図６に示すように工具本体部１０を下降端まで下動させた状態において、減速ギヤ部１６の下端面を通る仮想水平面Ｖを想定したときに、この仮想水平面Ｖより下方かつテーブル２０の上面よりも上方の領域Ｓにおける刃先に向けて照射されるように３つのＬＥＤ６２～６２の照射方向が設定されている。 In this way, the illumination device 60 is attached at a position offset to the right side with respect to the rotary blade 12 in front view, and the three LEDs 62 to 62 are inclined in the irradiation direction downward in side view and leftward in plan view. By being accommodated in the lighting case 63 in such a posture, the cutting edge (cutting part) of the rotary blade 12 is efficiently illuminated. In the present embodiment, when a virtual horizontal plane V passing through the lower end surface of the reduction gear unit 16 is assumed in a state where the tool body 10 is moved down to the lower end as shown in FIG. The irradiation directions of the three LEDs 62 to 62 are set so that the irradiation is performed toward the cutting edge in the region S above the upper surface of the table 20.
　以上のように構成した卓上切断工具１によれば、テーブル２０上に切断材Ｗを位置決めするための位置決めフェンス５０は、使用位置と退避位置との間を移動操作可能な２つの可動フェンス５１，５２を備えている。第１可動フェンス５１は上下に回動可能に設けられ、第２可動フェンス５２は左右にスライド可能に設けられている。 According to the desktop cutting tool 1 configured as described above, the positioning fence 50 for positioning the cutting material W on the table 20 includes two movable fences 51 that can be moved between a use position and a retracted position. 52. The 1st movable fence 51 is provided so that rotation up and down is possible, and the 2nd movable fence 52 is provided so that sliding to right and left is possible.
　図１２，１３に示すように回転刃具１２をテーブル面に対して直角に位置させた直角きり作業では、第１及び第２可動フェンス５１，５２をそれぞれ使用位置に位置させておくことができる。第１及び第２可動フェンス５１，５２をそれぞれ使用位置に位置させておくことにより、左右フェンス５０Ｌ，５０Ｒを回転刃具１２に最大限接近させた状態とすることができ、これにより切断材Ｗの位置決めをより確実に行うことができ、また切断粉等の後方への飛散を効率よく防止することができる。 As shown in FIGS. 12 and 13, the first and second movable fences 51 and 52 can be positioned at the use positions in the right-angle cutting operation in which the rotary blade 12 is positioned at a right angle to the table surface. By positioning the first and second movable fences 51 and 52 at the use positions, respectively, the left and right fences 50L and 50R can be brought into a state of being as close as possible to the rotary blade 12, and thereby the cutting material W Positioning can be performed more reliably, and scattering of cutting powder and the like to the rear can be efficiently prevented.
　図１４，１５に示すように第１可動フェンス５１を右側へ僅かにスライドさせて係合解除位置に移動させると、係合軸部５８が係合凹部５１ｃ内で相対変位して開口の上方に変位し、これにより当該第１可動フェンス５１を上方へ回動可能な状態となる。 As shown in FIGS. 14 and 15, when the first movable fence 51 is slightly slid to the right and moved to the disengagement position, the engagement shaft portion 58 is relatively displaced in the engagement recess 51c and above the opening. Thus, the first movable fence 51 can be rotated upward.
　図１６，１７に示すように第１可動フェンス５１を支軸５７を中心にして上方へ回動させて左右に反転させることにより当該第１可動フェンス５１を退避位置に移動させることができる。こうして第１可動フェンス５１を退避位置に移動させることにより、回転刃具１２を例えば左側に４５°傾斜させて傾斜切りを行うことができる。この段階で、第２可動フェンス５２は使用位置に位置させたまま傾斜切りを行うことができる。 As shown in FIGS. 16 and 17, the first movable fence 51 can be moved to the retracted position by rotating the first movable fence 51 around the support shaft 57 and reversing it left and right. By moving the first movable fence 51 to the retracted position in this manner, the rotary blade 12 can be inclined and cut by, for example, 45 ° to the left. At this stage, the second movable fence 52 can be cut while being kept in the use position.
　図１８，１９に示すように第１可動フェンス５１を退避位置に移動させた後、さらに第２可動フェンス５２を左方へスライドさせて退避位置に移動させることができる。第２可動フェンス５２を退避位置に移動させることにより、左側フェンス５０Ｒの高さを実質的に基台部５３の高さまで低くすることができる。この状態では、図８，９に示すように工具本体１０をさらに左側へ大きな角度で傾斜させて傾斜切りを行うことができる。 18 and 19, after the first movable fence 51 is moved to the retracted position, the second movable fence 52 can be further slid leftward and moved to the retracted position. By moving the second movable fence 52 to the retracted position, the height of the left fence 50 </ b> R can be substantially reduced to the height of the base portion 53. In this state, as shown in FIGS. 8 and 9, the tool body 10 can be further tilted to the left by a large angle to perform tilt cutting.
　このように、第１可動フェンス５１は、第２可動フェンス５１を使用位置に位置させた状態で退避位置に移動させることができる。このため、第１可動フェンス５１のみを上方へ回動操作して使用位置から退避位置に移動させた状態と、第１及び第２可動フェンス５１，５２の双方を使用位置から退避位置に移動させた状態とを選択することができることから、回転刃具１２若しくは工具本体部１０に対して干渉しない範囲で極力回転刃具１２に近い部位に位置決め面を位置させて切断加工を行うことができる。 Thus, the first movable fence 51 can be moved to the retracted position with the second movable fence 51 positioned at the use position. Therefore, only the first movable fence 51 is pivoted upward to move it from the use position to the retracted position, and both the first and second movable fences 51 and 52 are moved from the use position to the retracted position. Therefore, it is possible to perform cutting by positioning the positioning surface as close as possible to the rotary blade 12 within a range that does not interfere with the rotary blade 12 or the tool main body 10.
　以上説明した実施形態には種々変更を加えることができる。例えば、第１及び第２可動フェンス５１，５２に加えて、基台部５３についても位置決め面５３ａを設定した構成を例示したが、基台部５３については位置決め面５３ａを省略してもよい。また、第１及び第２可動フェンス５１，５２の位置決め面５１ａ，５２ａの一方を省略してもよい。位置決めフェンス５０の機能として、切断材Ｗの位置決め機能に加えて、切断粉若しくは切断片の後方へ飛散を防止する切断粉等飛散防止機能を備えることを考慮すれば、第１又は第２可動フェンス５１，５２若しくは基台部５３について何れか一つの前面に位置決め面を設定し、その他については上記の切断粉等飛散防止機能を発揮させる構成とすることができる。 Various modifications can be made to the embodiment described above. For example, in addition to the first and second movable fences 51, 52, the configuration in which the positioning surface 53 a is set for the base portion 53 is illustrated, but the positioning surface 53 a may be omitted for the base portion 53. In addition, one of the positioning surfaces 51a and 52a of the first and second movable fences 51 and 52 may be omitted. In consideration of the function of the positioning fence 50, in addition to the function of positioning the cutting material W, the first or second movable fence is considered to have a function of preventing the scattering of cutting powder or cutting pieces, etc. A positioning surface is set on one of the front surfaces of 51 and 52 or the base portion 53, and the others can be configured to exhibit the function of preventing scattering of cutting powder and the like.
　また、左側フェンス５０Ｌについて、第１、第２可動フェンス５１，５２を設定した構成を例示したが、右側フェンス５０Ｒについて設定してもよく、さらには左右両側について例示した可動フェンスを設定してもよい。 Moreover, although the structure which set the 1st, 2nd movable fences 51 and 52 was illustrated about the left fence 50L, you may set about the right fence 50R, Furthermore, even if the movable fence illustrated about both right and left sides is set. Good.
