Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は円形刃を所定の角度傾斜させ、これを
回転させて木板に溝を切削する場合に用いる溝形
成用カツターに関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a groove-forming cutter used when cutting grooves in a wooden board by rotating a circular blade at a predetermined angle.

[Conventional technology]

この種のカツターは従来、円形刃を挟んで保持
する一対の傾斜保持板はスナツプリング等で、固
定する構造のため、特殊な工具を用いなければ着
脱できない。特に締付けの際にずれて狂いを生
じ、ずれの矯正に手数を要する。 Conventionally, this type of cutter has a structure in which the pair of inclined retaining plates that hold the circular blade in place are fixed using a snap spring or the like, and therefore cannot be attached or detached without using a special tool. Particularly when tightening, deviations occur and errors occur, and it takes time and effort to correct the deviations.

[The problem that the idea aims to solve]

本考案の課題は、前記従来の欠点を解消し、簡
単に着脱でき、かつずれることなく確実に固定で
きる構造のカツターを提供することにある。 An object of the present invention is to provide a cutter having a structure that eliminates the above-mentioned conventional drawbacks, and that can be easily attached and detached, and that can be securely fixed without slipping.

[Means to solve the problem]

本考案の手段は円形刃が回転軸に対して傾斜状
態で止められる傾斜保持板を、人手で操作できる
ゴムリングにより固定し、釘などの細い線材で前
記のゴムリングを取外し可能にしたことである。 The means of the present invention is that an inclined holding plate, on which the circular blade is held at an angle with respect to the rotation axis, is fixed by a rubber ring that can be operated manually, and the rubber ring can be removed using a thin wire such as a nail. be.

Reference numeral 3 denotes a flange that holds the circular blade 1 between them, and the protrusion 4 protruding from each flange 2 and 3 is inserted into a hole 5 made in the circular blade 1, and is fitted into the pinching pipe part 6 of the other flange. Fix and hold the circular blade 1.

を止めるナツトを示す。 7 and 8 are annular inclined retaining plates that are attached to both flanges 2 and 3.
A circular blade 1 and a flange 2 are further sandwiched on the outside of the
3 is supported in an inclined manner with respect to the rotating shaft 9. Therefore, the inner surfaces 7', 8' in contact with the flanges 2, 3 are not perpendicular to the rotating shaft 9, but are inclined at a certain angle. One inclined holding plate 7 is integrally provided with a boss 10 having an inner diameter surface that matches the rotating shaft 9.
The inner diameter surface of the other inclined holding plate 8 fits into the tip of 0,
and an arcuate surface 11 in contact with the center hole 1' of the circular blade 1.
has been formed. In addition, a circumferential groove 13 is provided in the notched circular portion 12 at the tip of the boss, and as shown in FIG. 3, a rubber ring 14 is fitted into the circumferential groove 13, and the inclined retaining plate 8 is pressed to firmly fix the entire body by the elasticity of the rubber ring. do. Reference numeral 15 indicates a knob pin for connecting both inclined retaining plates 7 and 8, and reference numeral 16 indicates a nut that is screwed into the rotating shaft to fix the cutter of the present invention.

〔effect〕

本考案によればゴムリング１４′は人手で円周

に対してずれるおそれはない。 According to the present invention, the rubber ring 14' can be manually fitted into the circumferential groove 13, and the rubber ring 14 can be easily removed using an arbitrary thin rod 17, as shown in FIG. Therefore, it is advantageous in terms of work. In particular, since the rubber ring has elasticity, the inclined retainer plate is constantly pressed, and the "slippage" that occurs when inserting a washer and tightening with a nut as in the conventional case.
This prevents the scale reference point of the inclined holding plate from shifting with respect to the scale of the flange.
