Abstract

PURPOSE:To prevent intrusion of dust into a slide mechanism by providing a casing with pressurizing means for keeping the pressure in the slide mechanism higher than that in the space in the casing. CONSTITUTION:A cutting edge 12 is attached to the extreme end of a spindle 10. A casing 13 is composed of a cover member 14 and body member 15, and a slide mechanism 16 has a cover member 13 horizontally slidable a certain distance with respect to a body member 14. An exhaust pipe 17 extends from a portion of the casing body 15, and a dust collector 18 is connected to the exhaust pipe 17. An air inlet port 21 is formed at a portion of the body 15 of the casing 13 and is connected through a connecting pipe 22 to a compressor 23. The compressor 23 delivers pressurized air flow to the slide mechanism 16 to keep the pressure in the slide mechanism 16 higher than that in a space 19 in the casing 13.

機構に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an improvement in the dust-proof mechanism of a processing machine that cuts resin boards such as printed wiring boards, and in particular, to prevent cutting dust from entering the mechanical parts near the cutting area. The present invention relates to a dustproof mechanism for a cutting machine that can prevent intrusion.

As shown in FIG. 2, this step is a step of removing an outer frame 2 that is unnecessary as a product from a printed wiring board 1 comprising a resin plate with copper foil, and a cutting machine is used for this processing. In the figure, 3 indicates a printed wiring board as a product, and 4 indicates an area (shaded area) to be cut by the cutting blade.

。FIG. 3 is a cross-sectional view of the main parts of the conventional cutting machine mentioned above. 10 is a spindle, 11 is a spindle cover, 12 is a cutting blade attached to the tip of the spindle, and 13 is a casing consisting of a lid 14 and a main body 15. , 16 connects the lid 13 to the main body 1
17 is an exhaust pipe provided in a part of the casing body 15, and 18 is a dust collector connected to the exhaust pipe 17.

ライド機構部１６に粉塵が入り込むとスライド機構は作
動しなくなるといった欠点があった。By the way, when resin such as a printed wiring board is cut, the cut resin becomes dust, which is guided by the rotation of the spindle 10 and flies up in the space 19 in the casing 13 surrounding the spindle 10. Most of this dust passes through the exhaust pipe 17 and is collected in the dust collector 18. However, since there is a gap 20 between the lid 14 and the main body 15, which is provided for sliding and rotation of the slide mechanism 16, dust also enters the slide mechanism 16 through the gap 20. There is a drawback that if dust enters the slide mechanism section 16 in this way, the slide mechanism will no longer operate.

〔問題点を解決するための手段〕 本発明はスライド機構部１６への粉塵の侵入を防止する
ことを目的とし、その手段は、 第１図に示すように、ケーシング１３に前記機構部１６

ってなされる。[Means for Solving the Problems] The present invention aims to prevent dust from entering the slide mechanism section 16, and its means include, as shown in FIG.
This is done by a dust-proof mechanism of the cutting machine that is equipped with a pressurizing means 23 that makes the pressure inside the casing higher than the pressure in the space 19 inside the casing.

〔作用〕[Effect]

上記防塵機構はスライド機構部の圧力をケーシング内の
空間部の圧力より高くすることにより、粉塵のスライド
機構部への侵入を防いだものである。The dustproof mechanism prevents dust from entering the slide mechanism by making the pressure in the slide mechanism higher than the pressure in the space inside the casing.

〔実施例〕〔Example〕

以下、図面を参照して本考案の実施例を詳細に説明する
。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

第１図は本発明の一実施例の要部断面図である。FIG. 1 is a sectional view of a main part of an embodiment of the present invention.

なお第３図と同等部位には同一符号を付して示した。本

設置したことである。Note that the same parts as in FIG. 3 are indicated with the same reference numerals. This figure differs from FIG. 2 in that an air inlet 21 is provided in a part of the main body 15 of the casing 13, and a compressor 23 is installed via a connecting pipe 22 connected to this air inlet 21.

コンプレッサ２３より圧気流をスライド機構部１６へ送

３内の空間部１９の圧力より高く保つ。こうすることで
、切削によって発生した粉塵は間隙部２０から噴出する

められる。The compressor 23 sends out a pressurized air flow to the slide mechanism section 16, and the pressure inside this slide mechanism section 16 is transferred to the casing 1.
The pressure is maintained higher than the pressure in the space 19 within the chamber 3. In this way, all the dust generated by cutting is collected into the dust collector by the pressure air flow ejected from the gap 20 as shown by the arrow.

なお、本実施例では機構部をスライド機構として説明し
たが、本発明はスライド機構に限定するものでないこと
は勿論である。In this embodiment, the mechanism section has been described as a slide mechanism, but it goes without saying that the present invention is not limited to the slide mechanism.

また、被加工体にプリイト配線基板を用いたが、これに
限らず切削によって粉塵が生じるものにおいて本発明は
通用可能である。Further, although a printed circuit board is used as the workpiece, the present invention is not limited to this, and the present invention can be applied to any object in which dust is generated by cutting.

〔発明の効果〕〔Effect of the invention〕

、スライド機構部への粉塵の侵入が防止できる。従って
、本発明の切削加工機の防塵機構はスライド機構部の故
障が皆無となり、実用的効果大なるものである。As explained above, according to the present invention, since the pressure inside the slide mechanism is made higher than the pressure in the space inside the casing, it is possible to prevent dust from entering the slide mechanism. Therefore, the dustproof mechanism of the cutting machine of the present invention has no failures in the slide mechanism, and has great practical effects.
