Description

本発明は、ワーク（被加工物）を加工する加工部と、該加工部の制御を行う制御部とを有する工作機械に関する。 The present invention relates to a machine tool including a processing unit that processes a workpiece (workpiece) and a control unit that controls the processing unit.

工作機械は、ワークを加工する加工部と、当該加工部を制御する制御部（制御盤）とを有する。制御部が加工部の制御を行うことにより、加工部がワークを加工する。通常、制御部は加工部の背面に設けられており、開口部に扉が設けられた筐体に、加工部の制御を行う回路を実装した回路実装部及び電源部等が収納されている。 The machine tool includes a processing unit that processes a workpiece and a control unit (control panel) that controls the processing unit. When the control unit controls the processing unit, the processing unit processes the workpiece. Usually, the control unit is provided on the back surface of the processing unit, and a circuit mounting unit, a power supply unit, and the like in which a circuit for controlling the processing unit is mounted are accommodated in a housing having a door provided in the opening.

一般に電気機器において、その稼働期間中に内部を点検したり、部品を交換したり、設定の変更を行ったりするために、筐体の扉を開いて内部を見る必要がある。工作機械の制御部も同様に定期的な保守点検等を行うために、筐体の扉を開く必要がある。
従って、扉を開くときのスペースを確保する必要があり、扉が大きい場合、そのスペースを大きく取る必要があり、結果的に工作機械の前後方向の設置スペースが大きくなるという問題があった。扉を小さくした場合、筐体に占める開口面積の割合が小さくなるので、内奥に手が届きにくくなり、作業がしづらくなる。
また、２枚の観音開きタイプの扉を用いることにした場合、各扉につき筐体への枢支構造が必要であり、２枚の扉の連結部分も含めて部品点数が増加し、組み立てコストも増加して全体的にコストが増加するという問題がある。 In general, in order to inspect the interior, replace parts, or change settings in an electrical device, it is necessary to open the housing door and look inside. Similarly, it is necessary for the control unit of the machine tool to open the door of the housing in order to perform periodic maintenance and inspection.
Therefore, it is necessary to secure a space for opening the door. When the door is large, it is necessary to make the space large, resulting in a problem that the installation space in the front-rear direction of the machine tool becomes large. When the door is made small, the ratio of the opening area to the housing is small, so it is difficult to reach the inside and the work is difficult.
In addition, when two double doors are used, a pivotal support structure is required for each door, the number of parts including the connecting part of the two doors increases, and the assembly cost also increases. There is a problem that the cost increases as a whole.

このような工作機械において、付属機器として、ワークの加工により生じた加工屑を搬送するチップコンベアを設けたものがある。このチップコンベアは、制御部の下側に、すなわち加工部の下側から加工部の後方に延びるように略水平に設けられた水平部と、該水平部の後端部から斜め後ろ上方に延設された傾斜部とを有している。傾斜部の後ろ下方に、チップコンベアにより搬送された加工屑を回収するための回収ボックスが設けられている。
以上のように構成されているので、傾斜部及び回収ボックスは、制御部の扉を開けた場合に扉と干渉しないように、制御部の後方に配置する必要があり、付属機器を含めた工作機械の設置スペースが大きくなるという問題があった。
特許文献１には、傾斜部との干渉を回避すべく、制御部の扉の自由端部の下方に切欠きを設けた工作機械の発明が開示されている。 In such a machine tool, there is an accessory device provided with a chip conveyor that conveys processing waste generated by processing a workpiece. This chip conveyor extends below the control unit, that is, a horizontal portion provided substantially horizontally so as to extend from the lower side of the processing unit to the rear of the processing unit, and obliquely upward and rearward from the rear end of the horizontal unit. And an inclined portion provided. A collection box for collecting the processing waste conveyed by the chip conveyor is provided below and below the inclined portion.
Since it is configured as described above, it is necessary to arrange the inclined part and the collection box behind the control unit so that it does not interfere with the door when the control unit door is opened. There was a problem that the installation space of the machine became large.
Patent Document 1 discloses an invention of a machine tool in which a notch is provided below a free end portion of a door of a control unit in order to avoid interference with an inclined portion.

図１１は扉６が完全に開いた状態から閉じるまでの途中の状態を示す制御部４の斜視図、図１２は図１１のXII −XII 線断面図、図１３は図１２の連結部分XIII の拡大図である。
図１１は、板体８が折れ曲がっている状態で、図６の状態から板体７を略９０度反時計回りに回転させた状態を示す。このとき、板体８の先端部が筐体５の開口部に向かうことになる。 11 is a perspective view of the control unit 4 showing a state in the middle of the door 6 from the fully opened state to the closed state, FIG. 12 is a sectional view taken along the line XII-XII in FIG. 11, and FIG. It is an enlarged view.
FIG. 11 shows a state in which the plate body 7 is rotated approximately 90 degrees counterclockwise from the state of FIG. 6 in a state where the plate body 8 is bent. At this time, the front end of the plate body 8 is directed toward the opening of the housing 5.

図１４は扉６が完全に閉じた状態を示す制御部４の斜視図、図１５は図１４のXV−XV線断面図、図１６は図１５の連結部分XVI の拡大図である。
扉６の連結部分を筐体５の開口側に押さえつつ、板体８の自由端部を筐体５の開口部の幅方向端部に合わせることによって扉６が閉まり、筐体５の開口部が閉塞される。張出部７２，７３，７４，８２，８３，８４は、筐体５の嵌合枠部５１に嵌められる。
このとき、図１６に示すように、連結部分で板本体７１の外側に板本体８１が重なるので蝶番９が視認されず、外観品位は良好である。上述したように、板本体７１の外面には緩衝部材７６が設けられているので、板本体７１に板本体８１が重なる場合に傷つくことがなく、板本体８１が板本体７１に密着される。また扉６が閉じた後、緩衝部材７６は切削油等が筐体５内に浸入することを防止する。 14 is a perspective view of the control unit 4 showing a state in which the door 6 is completely closed, FIG. 15 is a cross-sectional view taken along the line XV-XV in FIG. 14, and FIG. 16 is an enlarged view of the connecting portion XVI in FIG.

Is blocked. The overhang portions 72, 73, 74, 82, 83, 84 are fitted into the fitting frame portion 51 of the housing 5.
At this time, as shown in FIG. 16, since the plate body 81 overlaps the outside of the plate body 71 at the connecting portion, the hinge 9 is not visually recognized, and the appearance quality is good. As described above, since the buffer member 76 is provided on the outer surface of the plate body 71, the plate body 81 is brought into close contact with the plate body 71 without being damaged when the plate body 81 overlaps the plate body 71. Further, after the door 6 is closed, the buffer member 76 prevents cutting oil or the like from entering the housing 5.

本実施の形態のマシニングセンタ１は以上のように構成されているので、最大でも板体８の横幅分、扉６を筐体５から突出させるのみで、扉６を開閉することができる。板体７の張出部７２，７３は傾斜部７５を有し、連結端部が幅狭になっているので、板体８を板体７側に折り畳む場合に干渉せず、板体８を板体７側に折り畳んだ状態で円滑に扉６を開閉することができる。扉６を半分に折り畳んだ状態で開閉するので、扉開閉用のスペースは従来の一枚扉の場合の略半分で済み、マシニングセンタ１の前後方向の長さを短くすることができ、設置スペースを低減することができる。 Since the machining center 1 of the present embodiment is configured as described above, the door 6 can be opened and closed only by protruding the door 6 from the housing 5 by the width of the plate 8 at the maximum. Since the projecting portions 72 and 73 of the plate body 7 have inclined portions 75 and the connecting end portions are narrow, the plate body 8 is not interfered when the plate body 8 is folded to the plate body 7 side. The door 6 can be smoothly opened and closed while being folded to the plate body 7 side. Since the door 6 is opened and closed with the door folded in half, the door opening / closing space is almost half that of a conventional single door, the length of the machining center 1 in the front-rear direction can be shortened, and the installation space can be reduced. Can be reduced.

図２に示すように、チップコンベア１５、回収ボックス１９、及びクーラントタンク２０等の付属機器は、扉６が開いた場合にチップコンベア１５の傾斜部１５２に扉６が当たらないように配置すればよく、本実施の形態の場合、扉６は略半分に折り畳んだ状態で開くので、従来の一枚扉の場合と比較して、扉の半分だけ、付属機器の配置の前後方向の長さを短くすることができる。本実施の形態の扉６のように、板体８の自由端部の下部に切り欠きを設けることで、前記前後方向の長さをより短くすることができる。以上のように、本実施の形態においては、付属機器を含めたマシニングセンタ１の設置スペースを低減することができる。 As shown in FIG. 2, accessory devices such as the chip conveyor 15, the recovery box 19, and the coolant tank 20 are arranged so that the door 6 does not hit the inclined portion 152 of the chip conveyor 15 when the door 6 is opened. Well, in the case of the present embodiment, the door 6 is opened in a state of being folded in substantially half, so that the length of the accessory arrangement in the front-rear direction is only half of the door compared to the case of the conventional single door. Can be shortened. Like the door 6 of the present embodiment, the length in the front-rear direction can be further shortened by providing a notch in the lower portion of the free end portion of the plate body 8. As described above, in the present embodiment, the installation space of the machining center 1 including the accessory devices can be reduced.
