Description

この発明は、ワークに対して接離可能な主軸ヘッド（主軸台）の先端部に位置するフライスなどの切削用工具の軸線周りの回転によってワークを切削加工する工作機械において、ワークの切削加工により発生する切屑を吸引して捕集する切屑吸引捕集機における切屑吸引フード装置に関する。   The present invention relates to a machine tool that cuts a workpiece by rotating around the axis of a cutting tool such as a milling cutter located at the tip of a spindle head (headstock) that can be brought into contact with and separated from the workpiece. The present invention relates to a chip suction hood device in a chip suction collector that sucks and collects generated chips.

周知のように、この種の切屑吸引フード装置は、主要手段として、主軸ヘッドの先端部近傍に同心的に組み付けるとともにダクトを介してブロワ等の吸引エア流発生手段付きの切屑捕集装置に接続する吸引フードを含んでいるが、慣用の吸引フードは、切屑の吸引口を、工具によるワークの切削加工時にワークの切削加工点の周囲部に実質上密接する状態で、主軸ヘッドに組み付ける構成になっている（例えば、特許文献１、２、３参照）。   As is well known, this type of chip suction hood device is concentrically assembled as a main means near the tip of the spindle head and connected to a chip collecting device with suction air flow generating means such as a blower via a duct. The conventional suction hood has a configuration in which the chip suction port is assembled to the spindle head in a state where the chip suction port is substantially in close contact with the peripheral portion of the workpiece cutting point when cutting the workpiece with a tool. (For example, see Patent Documents 1, 2, and 3).

この慣用の吸引フードは、主軸ヘッド、従って工具の軸線方向（Ｚ軸）の移動やテーブルの平面移動（Ｘ軸移動、Ｙ軸移動）が比較的単純で狭い範囲の場合には適用可能であるが、エンドミルによる金型加工の場合のように、工具とテーブルがＺ軸、Ｘ軸、Ｙ軸の複数軸において多彩にかつ広範囲に移動する加工の場合には、これらの移動の支障になるため、実質上適用することが不可能である。
特開平８ー７１８８６号公報 特開平８ー７１８８４号公報 実開平７ー３３５１３号公報 This conventional suction hood is applicable when the movement of the spindle head and hence the tool in the axial direction (Z-axis) and the table plane movement (X-axis movement, Y-axis movement) are relatively simple and narrow. However, if the tool and table move in various and wide ranges on multiple axes, such as the Z axis, X axis, and Y axis, as in the case of die machining with an end mill, these movements will be hindered. It is virtually impossible to apply.

The tool 34 is used in the assembled state in which the spindle head protrudes from the suction port 14 of the suction nozzle 13 of the suction hood 11, and the spindle head 31 is cut from the standby position above the table 35 so that the tool 34 engages the workpiece 36. In the process of cutting the work 36 while lowering the position to the position and rotating the tool 34 around the axis, air is blown from all the air blowing nozzles 21, so that the periphery of the suction port 14 and the work 36 cutting point. A cylindrical air curtain consisting of a spiral air flow is formed between the air curtain and the corresponding part of the table 35, while the air curtain is the same as the air curtain. While swirling in the direction toward the suction port 14 of the suction hood 11 to form a tornado air flow.

このエアカーテン内に形成される竜巻エア流により、ワーク３６の切削加工によって生じる切屑は的確に吸引口１４を通して吸引フード１１の吸引筒１２内に吸引された後、吸引筒出口１８からポケット２５及び外筒２０のダクト接続口２３を通して切屑吸引フード装置１０を離れ、この後吸引ダクト２４を通して捕集部に吸引されていく。   After the tornado air flow formed in the air curtain, chips generated by cutting the workpiece 36 are accurately sucked into the suction cylinder 12 of the suction hood 11 through the suction port 14, and then the pocket 25 and the The chip suction hood device 10 is left through the duct connection port 23 of the outer cylinder 20, and is then sucked into the collection portion through the suction duct 24.

In particular, the outer side of the spindle head fitting cylinder is arranged so that a series of arc-shaped or annular pockets are formed around the shaft communicating with all the suction cylinder outlets. The tornado air flow is generated by high-speed air blowing through the air blowing port by deforming the contour, separating from the spindle head via a feed screw mechanism, or using a tool having an air blowing port at the tip. It can be implemented in various forms such as being accelerated.
