本考案は、切断時に発生する粉塵に対し切断砥
石を揺動させる支点部への切断機における防塵構
造に関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a dust-proof structure in a cutting machine that swings a cutting wheel against dust generated during cutting.
従来の切断機について、第３，４図を用いて説

ことがあつた。
A conventional cutting machine will be explained using FIGS. 3 and 4. Dust generated when cutting an object is scattered as shown by the arrow in FIG. 3. For this reason,
Dust adheres to the space between the support stand and the arm, which is swingably held with the shaft as a fulcrum, and furthermore, dust enters the fitting part of the support stand and shaft due to the swing of the arm, causing the support stand to become damaged. and the shaft sometimes wore out.
これにより、支持台およびシヤフトにガタが生
じ、切断作業時、切断トイシが被切断材に直角に
当らないため切断精度が確保できないばかりか、
切断トイシの揺れが大きくなり切断トイシが割れ
る危険性を持つていた。 This causes play in the support stand and shaft, and during cutting work, the cutting wheel does not hit the material to be cut at right angles, which not only makes it impossible to ensure cutting accuracy.
The shaking of the cutting tool would increase and there was a risk that the cutting tool would break.
また、支持台に別体の防塵カバーを設けたもの
があるが、ネジ止め等の必要があり、原価の高い
ものとなつていた。 In addition, there are devices in which a separate dust-proof cover is provided on the support base, but this requires screwing, etc., resulting in a high cost.
本考案の目的は、上記した従来技術の欠点をな
くし、高精度でしかも安全な切断作業を提供する
ものである。
The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art and provide a highly accurate and safe cutting operation.
本考案は、被切断材を切断する際に発生する切

This invention focuses on the point that wear can be prevented by preventing the adhesion and intrusion of chips that are generated when cutting the material to be cut.This invention focuses on the point that wear can be prevented by preventing the adhesion and intrusion of chips that are generated when cutting the material to be cut. The aim is to provide a cover that is integrated with the arm by devising a shape.

第２図は第１図のＡ方向から見た側面図である。
FIG. 1 is a front view showing an embodiment of the present invention.
FIG. 2 is a side view seen from direction A in FIG. 1.

The support base, 7 is a protrusion provided on the support base 6, and 5 is a dustproof cover protruding around the protrusion 7 provided on the support base 6 and the sliding portion of the arm 3.
被切断材１１を切断する際に発生する粉塵は点
線の矢印の方向に飛散するが、防塵覆い５により

According to the present invention, a cover is attached to cover the joint between the support base and the arm that is swingably held between the support base and the shaft, which prevents dust from entering and significantly reduces wear on the joint between the support base and the shaft. It is possible to reduce the Therefore, cutting accuracy can be maintained, and the risk of the cutting tool being broken due to increased vibration of the cutting tool can also be avoided.
また、支持台に突起部を設け、この突起部分を
