例えば図３に示すように、特開２００４‐２５５４９４号公報には、室５内にパテーション６を設け、このパテーション６内にカバー７を付けた機械１を据え付け、室５内に設けた温調節器３からパテーション６および装置カバー７内にコンプレッサー２を介して高精度に温度制御された圧縮空気を空気配管４により矢印のように導入し、機械および加工エリアの温度変動幅を小さくし、高精度に温度制御する方法が知られている。
For example, as shown in FIG. 3, Japanese Patent Application Laid-Open No. 2004-255494 discloses that a partition 6 is provided in a chamber 5, a machine 1 having a cover 7 is installed in the partition 6, and temperature control provided in the chamber 5 Compressed air, which is temperature-controlled with high accuracy through the compressor 2 from the vessel 3 into the partition 6 and the apparatus cover 7 through the air pipe 4 as shown by the arrows, reduces the temperature fluctuation range of the machine and the processing area, A method of controlling the temperature with accuracy is known.

しかしながら、従来方法ではカバーの付いた機械をパテーションで覆うため、設置スペースが大きかった。
However, in the conventional method, since the machine with the cover is covered with a partition , the installation space is large.

前述の欠点を解消するために、発明者は、設置スペースを小さく、しかも高精度に温度制御する方法を種々検討した結果、精密加工機の機械装置のカバーに温度調節機構を設け、このカバー内を高精度に温度制御すれば良いという結論に達し、本発明に至った。
In order to eliminate the above-mentioned drawbacks, the inventor has studied various methods for controlling the temperature with a small installation space and high accuracy. As a result, the temperature control mechanism is provided in the cover of the mechanical device of the precision processing machine . The conclusion has been reached that the temperature should be controlled with high accuracy, and the present invention has been reached.

前述の目的を達成するため本発明は、精密加工機を覆うカバーであって、カバーの屋根は、温度調節装置からの空気の入口から奥に向って下方向に傾斜させるとともに、屋根の下部にそなえられ、床面に対して水平で、かつ小孔を複数個設けた天井板を設け、屋根と天井板とで形成する空間部を介して、天井板の小孔から温度制御された空気を温度調節装置から前記カバー内に導入しカバー内を恒温状態に保つ恒温室と、
を備えたことを特徴とする精密加工機のカバーとした。
In order to achieve the above-mentioned object, the present invention is a cover that covers a precision processing machine, and the roof of the cover is inclined downward from the inlet of air from the temperature control device and at the bottom of the roof. It is provided with a ceiling plate that is horizontal to the floor and provided with a plurality of small holes, and air whose temperature is controlled from the small holes in the ceiling plate through a space formed by the roof and the ceiling plate. A temperature-controlled room which is introduced from the temperature control device into the cover and keeps the temperature in the cover at a constant temperature;
It was made into the cover of the precision processing machine characterized by having.

またカバーは、加工機およびその加工域を区別するオイルパンを兼ねた仕切り板を設けるとともに、加工域のオイルミストを回収するミストコレクタと、外気を選択的に出し入れするドアを設け、選択的にドアを開閉すれば内部循環型或いは内部循環型＋外気導入型とすることが可能な精密加工機のカバーとなる。
In addition, the cover has a partition plate that also serves as an oil pan that distinguishes the processing machine and its processing area, a mist collector that collects oil mist in the processing area , and a door that selectively allows outside air to be taken in and out. By opening and closing the door, it becomes a cover for a precision processing machine that can be an internal circulation type or an internal circulation type + an outside air introduction type.

このカバーは、断熱材を用いることにより周囲の雰囲気からカバー内を恒温状態に保つことが可能な精密加工機のカバーとすることが出来る。また、このカバーは、さらに、その裾部分に柔軟な形状を取り得る部材を備えて構成し、精密加工機の設置される床の形状に対応可能にした。
This cover can be used as a cover for a precision processing machine capable of keeping the inside of the cover at a constant temperature from the surrounding atmosphere by using a heat insulating material. In addition, this cover is further provided with a member that can take a flexible shape at its hem, so that it can correspond to the shape of the floor on which the precision processing machine is installed.

この発明によれば設置スペースを小さく、しかも温度制御された空気を精密加工機のカバー内に送ることが出来る。
Reduce the installation space according to the present invention, moreover Ru came out to send to the temperature controlled to within the cover of the precision machine air.

次に本発明の一実施形態例を、図１および図２により説明する。
１０は、鎖線で示す精密な工作機械にて代表される精密加工機（以下単に加工機という）１１を覆うカバーで、このカバー１０の温度調節のための機器３０を収納する温度調節装置１２によりカバー１０の上部にある入口１３から温度制御された空気をカバー１０内に導入するようにしている。このカバー１０は、屋根１４を空気入口１３から前方、すなわち図中では右方）に向って下方向に傾斜させるとともに、小孔１５を複数個設けた床面ＦＬに対して水平の天井板１６を設けてあり、屋根１４と天井板１６の形成する空間部１７に温度制御された空気を導入し、導入された空気が矢印ａのようにカバー１０内の恒温室全体に行き亘るようにしてある。 Next, an embodiment of the present invention will be described with reference to FIGS.
Reference numeral 10 denotes a cover that covers a precision processing machine (hereinafter simply referred to as a processing machine) 11 represented by a precision machine tool indicated by a chain line, and a temperature adjusting device 12 that houses a device 30 for adjusting the temperature of the cover 10. The temperature-controlled air is introduced into the cover 10 from the inlet 13 at the top of the cover 10. The cover 10 inclines the roof 14 downward from the air inlet 13 toward the front, that is, to the right in the drawing, and is a ceiling plate 16 that is horizontal to the floor surface FL provided with a plurality of small holes 15. The temperature-controlled air is introduced into the space 17 formed by the roof 14 and the ceiling board 16 so that the introduced air reaches the entire temperature-controlled room in the cover 10 as indicated by an arrow a. is there.

またカバー１０は、ワーク加工のために恒温とすべき恒温室が加工機本体域１８と実際に加工動作が行われる加工域１９を別けるとともに、加工域１９における切削油等を受けるオイルパン２０を兼ねた仕切り板２１が設けてあり、この加工域１９の側面には加工域１９内のオイルミストを吸込むミストコレクタ２２が設けてある。
In addition, the cover 10 is provided with an oil pan 20 that receives a cutting oil or the like in the processing area 19 while a constant temperature room that should be kept at a constant temperature for processing the workpiece separates the processing machine main body area 18 from the processing area 19 in which the actual processing operation is performed. A partition plate 21 is also provided, and a mist collector 22 for sucking oil mist in the processing area 19 is provided on a side surface of the processing area 19.

さらにカバー１０の加工域１９上部にはドア２３、２４が設けてあり、このドア２３、２４を自動或いは手動により選択的に開閉し、被加工物を出し入れする。また、温度調節装置１２にある外気吸入扉２６から温度調節装置１２内に、自動又は手動制御により吸込む空気により、温度調節装置１２内の温度調節機器３０のヒータによりカバー１０内部の空気がオイルミスト等を吸込み爆発が起きないようにしている。無論、このカバーでは、オイルミストなどによる爆発防止には、温度変化をあまり心配しないような場合、必要に応じドア２３および２４を自動または手動により開閉制御し、空気を導入してもよい。
Furthermore, doors 23 and 24 are provided in the upper part of the processing area 19 of the cover 10, and the doors 23 and 24 are selectively opened and closed automatically or manually, and a workpiece is taken in and out. In addition, the air in the cover 10 is heated by the heater of the temperature adjusting device 30 in the temperature adjusting device 12 by the air sucked into the temperature adjusting device 12 from the outside air intake door 26 in the temperature adjusting device 12 by automatic or manual control. So that no explosion occurs. Of course, in this cover, in order to prevent an explosion caused by oil mist or the like, when there is not much concern about a temperature change, the doors 23 and 24 may be controlled to be opened or closed automatically or manually as needed to introduce air.

従って、カバー１０内は、ドア２３、２４を閉じ、外気吸入扉２６を閉めたときは内部循環型に、また外気吸入扉２６を開放したときは内部循環型＋外気導入型にすることが可能である。また、このカバー１０は、外部との断熱の効率を上げるため、ポリウレタン等の断熱材を用いている。なお、このカバーは、床面に対し裾の部分、つまりスカート４０の部分は、柔軟な変形可能な材料、例えばビニールシート、ナイロンシート、プラススチックシートなどの高分子のシートが使用され、空気流通が遮断されて、床の形状に対し対応可能にして、恒温を保持し易くしている。この部分厚手にし空気遮断をした不織布、織布などでも良いものと思われる。
Accordingly, the inside of the cover 10 can be of the internal circulation type when the doors 23 and 24 are closed and the outside air intake door 26 is closed, and the internal circulation type and the outside air introduction type when the outside air intake door 26 is opened. It is. Further, the cover 10, in order to increase the efficiency of thermal insulation from the outside, are used heat insulating material such as polyurethane. This cover is made of a flexible and deformable material such as a vinyl sheet, a nylon sheet, a plastic sheet, and the like at the hem part of the floor, that is, the skirt 40, and air circulation. Is cut off, making it possible to cope with the shape of the floor, making it easier to maintain a constant temperature. It seems that non-woven fabrics, woven fabrics, etc. that are thick and air-blocked may be used.

以上のように構成されているので、本発明のカバーでは、カバー内は温度調節された空気に満たされて恒温状態が確保される。しかも従来在った加工機のカバーの外側にパテーション等で囲う必要がなく、内部循環型および内部循環型＋外気導入型の選択可能にできる。さらに加工機の設置スペースも外部恒温室などが必要なく、機械と一体的に小さく出来る。
Since it is comprised as mentioned above, in the cover of this invention, the inside of a cover is satisfy | filled with the temperature-controlled air, and a constant temperature state is ensured. In addition, it is not necessary to enclose the outside of the cover of the conventional processing machine with a partition or the like, and the internal circulation type and the internal circulation type + the outside air introduction type can be selected. Furthermore, the installation space of the machine also there is no need for an external temperature-controlled room, Ru can be mechanically and integrally small.
