Description

【0001】
【発明の属する技術分野】
本発明は、墨線合わせ装置を有する卓上切断機に関する。
【0002】
【従来の技術】
従来技術を図5、6により説明する。従来の卓上切断機の墨線合わせ方法は、ベース1上面に被切断材5を支持するフェンス16とベース1のほぼ中央に埋設されたターンテーブル2上面に被切断材5を載置し、まずサイドハンドル3を緩め、ベース1とターンテーブル2との固定状態を解除し、のこ刃4が保持されている丸のこ部9を支持するターンテーブル2を回動させ、丸のこ部9を所望の位置に合わせる。所望の位置に達したところで、サイドハンドル3を締め付けてターンテーブル2とベース1を固定し、一方の手で丸のこ部9に保持したのこ刃4を被切断材5上面に当接する近くまで下方に揺動させて丸のこ部9を保持したまま、他方の手では被切断材5を左右に微調整させて、のこ刃4に被切断材5の墨線を合わせる。墨線を合わせた後、のこ刃4を保持した丸のこ部9を上限に戻し、のこ刃4をモーター10により軸15を介して回転させ、再度のこ刃4を保持した丸のこ部9を切り込み用ハンドル7で下方に揺動させて被切断材5に切り込みを与え、切断完了後、のこ刃4を保持した丸のこ部9を上限に戻し切断作業が完了する。
【0003】
【発明が解決しようとする課題】
従来の卓上切断機で墨線合わせをする場合、上記したように一方の手でのこ刃を保持した丸のこ部を一度下方に揺動させ保持したままで、もう一方の手では被切断材を左右に移動させ、のこ刃に墨線を合わせなくてはならないという困難さがあった。
【0004】
本発明の目的は、墨線合わせ時、被切断材を両手で微調整できることにより迅速かつ正確にのこ刃に墨線を合わせることができる卓上切断機を提供することである。
【0005】
【課題を解決するための手段】
上記目的は、被切断材を支持するベース部と、該ベース部上面に固定され被切断材を支持するフェンスと、前記ベースに水平回動自在に埋設したターンテーブルと、該ターンテーブル後方に連結されたホルダと、該ホルダ上部にベース部上面に対して上下揺動自在に設けた丸のこ部を有する卓上切断機において、前記ターンテーブル前方端部付近にスライドバーを立設し、前記のこ刃側面に対し平行に隣接するプレートを、前記スライドバーに上下動自在に設け、該プレートを被切断材の高さに追従し上下移動可能にしたことで達成される。
【0006】
【発明の実施の形態】
本発明の一実施形態を図1〜図4により説明する。図1は卓上切断機の正面図、図2は図1の左側面図、図3は図2の上面図、図4は図1の詳細図である。
【0007】
図において、ベース1上面に被切断材を支持するフェンス16を固定する。ベース1のほぼ中央にターンテーブル2を水平方向へ回動自在に埋設し、ベース1のみ又はベース1とターンテーブル2で被切断材5を載置する本発明ベース部を構成している。ターンテーブル2後部にホルダ6を連結し、ホルダ6上方には、切り込み用ハンドル7を備えモーター10により軸15を介して回転駆動するのこ刃4を保持した丸のこ部9が、ホルダシャフト8によりターンテーブル2上面に対し上下摺動自在に軸支され、スプリング12により上方に付勢されている。ターンテーブル2前方端部付近に配設した孔13にスライドバー14を立設し嵌合させ、スライドバー14に、のこ刃4側面に対し平行に隣接する墨線合わせプレート11を被切断材5上面に上下移動自在に嵌合させる。更に、スライドバー14をターンテーブル2の嵌合部孔13に左右移動可能に設け、スライドバー14片側側面とターンテーブル2嵌合部孔13の側面間に圧縮スプリング18が当接し付勢している。ターンテーブル2の圧縮スプリング18の対向する側面にはスライドバー14に直交した調整ノブ17をねじ嵌合し、調整ノブ端部でスライドバー14を係止している。
【0008】
上記構成において、ターンテーブル2上面に被切断材5をフェンス16に押し当てた状態で載置し、のこ刃4を保持した丸のこ部9を切り込み用ハンドル7で下方に揺動させ、調整ノブ17の回転によりスライドバー14と共に墨線合わせプレート11を横移動させのこ刃4の側面に隣接させる。その後、丸のこ部9を上限に戻す。
【0009】
被切断材5の墨線(通常被切断材へは切断位置を示す墨線が引かれている)と墨線合わせプレート11の側面を両手で被切断材5を移動して合わせ、被切断材5を固定後、のこ刃4を保持した丸のこ部9を切り込み用ハンドル7で下方に揺動させて被切断材5に切り込みを与え、切断完了後、のこ刃4を保持した丸のこ部9を上限に戻し切断作業が完了する。
【0010】
【発明の効果】
本発明によれば、ターンテーブル前方端部付近に、のこ刃側面に対し平行に隣接し、被切断材の高さに調整可能な墨線合わせプレートを被切断材上面に設けることにより、のこ刃を下降させなくても被切断材側面と墨線合わせプレートの側面を合わせれば切断位置の設定ができるため、両手で被切断材を移動できるようになることで微量な横移動も容易にできる。
また、墨線合わせプレートをのこ刃の厚みに対して左右調整可能としたので、厚さが異なるのこ刃を使用した場合にも容易に切断位置を正確に合わせることができる。

The prior art will be described with reference to FIGS. In a conventional table cutting machine, a black line alignment method includes a fence 16 for supporting the material 5 to be cut on the upper surface of the base 1 and the material 5 to be cut on the upper surface of the turntable 2 buried almost in the center of the base 1. Loosen the handle 3, release the fixed state between the base 1 and the turntable 2, rotate the turntable 2 supporting the circular saw 9 holding the saw blade 4, and remove the circular saw 9 Adjust to the desired position. When the desired position is reached, the side handle 3 is tightened to fix the turntable 2 and the base 1, and the saw blade 4 held by the circular saw 9 with one hand is brought into contact with the upper surface of the workpiece 5. The workpiece 5 is finely adjusted left and right with the other hand while holding the circular saw portion 9 by swinging downward to align the black line of the workpiece 5 with the saw blade 4. After aligning the black line, the circular saw 9 holding the saw blade 4 is returned to the upper limit, the saw blade 4 is rotated via the shaft 15 by the motor 10, and the circular saw holding the saw blade 4 again. The part 9 is swung downward by the cutting handle 7 to make a cut in the material 5 to be cut. After the cutting is completed, the circular saw 9 holding the saw blade 4 is returned to the upper limit, and the cutting operation is completed.
[0003]
[Problems to be solved by the invention]
When aligning a black line with a conventional tabletop cutting machine, as described above, while holding the circular saw part holding the saw blade with one hand downward and holding it, use the other hand to cut the workpiece. Has to be moved to the left and right, and the black line must be aligned with the saw blade.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a desktop cutter capable of quickly and accurately aligning a black line with a saw blade by finely adjusting a material to be cut with both hands at the time of black line alignment.
[0005]
[Means for Solving the Problems]
The object is to provide a base portion for supporting the material to be cut, a fence fixed to the upper surface of the base portion and supporting the material to be cut, a turntable embedded in the base so as to be rotatable horizontally, and connected to the rear of the turntable. In a desktop cutting machine having a holder and a circular saw portion provided on the upper portion of the holder so as to be able to swing up and down with respect to the upper surface of the base portion, a slide bar is erected near the front end of the turntable, This is achieved by providing a plate adjacent to the blade parallel to the side surface of the blade so as to be movable up and down on the slide bar, and allowing the plate to move up and down following the height of the material to be cut.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. 1 is a front view of the tabletop cutting machine, FIG. 2 is a left side view of FIG. 1, FIG. 3 is a top view of FIG. 2, and FIG. 4 is a detailed view of FIG.
[0007]
In the figure, a fence 16 for supporting a material to be cut is fixed to the upper surface of a base 1. A turntable 2 is buried in the center of the base 1 so as to be rotatable in the horizontal direction, and only the base 1 or the base 1 and the turntable 2 constitute a base portion of the present invention on which the workpiece 5 is placed. A holder 6 is connected to a rear portion of the turntable 2. Above the holder 6, a circular saw 9 holding a saw blade 4 provided with a notch handle 7 and rotationally driven by a motor 10 via a shaft 15 is provided with a holder shaft. 8 supports the upper surface of the turntable 2 so as to be slidable up and down, and is urged upward by a spring 12. A slide bar 14 is erected and fitted in a hole 13 provided near the front end of the turntable 2, and the black line aligning plate 11 adjacent to the side of the saw blade 4 in parallel with the side surface of the saw blade 4 is inserted into the slide bar 14. Fit to the upper surface so as to be movable up and down. Further, a slide bar 14 is provided in the fitting portion hole 13 of the turntable 2 so as to be movable left and right, and a compression spring 18 abuts and urges between one side surface of the slide bar 14 and the side surface of the turntable 2 fitting portion hole 13. I have. An adjustment knob 17 orthogonal to the slide bar 14 is screw-fitted to the opposite side of the compression spring 18 of the turntable 2, and the slide bar 14 is locked at the end of the adjustment knob.

In the above configuration, the workpiece 5 is placed on the upper surface of the turntable 2 while pressing the workpiece 5 against the fence 16, and the circular saw 9 holding the saw blade 4 is swung downward by the cutting handle 7, The rotation of the adjustment knob 17 causes the black line alignment plate 11 to move laterally together with the slide bar 14 so as to be adjacent to the side surface of the saw blade 4. Thereafter, the circular saw 9 is returned to the upper limit.
[0009]
The black line of the material to be cut 5 (usually a black line indicating the cutting position is drawn on the material to be cut) and the side of the black line alignment plate 11 by moving the material to be cut 5 with both hands to fix the material to be cut 5 Thereafter, the circular saw portion 9 holding the saw blade 4 is swung downward with the cutting handle 7 to cut the workpiece 5 and, after the cutting is completed, the circular saw portion holding the saw blade 4. 9 is returned to the upper limit, and the cutting operation is completed.
[0010]
【The invention's effect】
According to the present invention, the saw blade is provided near the front end of the turntable in parallel with the side surface of the saw blade and can be adjusted to the height of the cut material on the upper surface of the cut material. The cutting position can be set by aligning the side surface of the material to be cut with the side surface of the black line aligning plate without lowering the blade, so that the material to be cut can be moved with both hands, so that a slight lateral movement can be easily performed.
In addition, since the black line alignment plate can be adjusted left and right with respect to the thickness of the saw blade, the cutting position can be easily and accurately adjusted even when a saw blade having a different thickness is used.
