  The operation of the above-described machine tool cover device will be described below.

  As shown in FIGS. 1 to 4, the machine tool cover device can cover the cover opening 1. At this time, the interlocking member 22 is separated from the positioning member 21. The connecting end portions 231 of the slats 23 are separated from each other, and the extendable door unit 20 is in an extended state (extended state). The overlapping end portion 232 of the slat 23 abuts with the adjacent slat 23 so as to partially overlap.

  For this reason, the inner side 102 where the machine tool is provided is arranged so as to extend in the first axial direction X while the plurality of slats 23 partially overlap (that is, no gap is generated). It is possible to reduce the state where the chips and chips are leaked to the outer side 103 or the cutting fluid is scattered. Furthermore, since the shielding member 24 is provided in addition to the plurality of slats 23, even smaller and finer chips and chips can be confined in the inner side 102.

  When the blade is replaced, the drive unit 30 is activated to open the cover opening 1. The drive unit 30 operates the drive member 32 so as to slide along the first axial direction X and on the cylinder block 31. When the drive member 32 moves while moving along with the interlocking member 22 and approaches the positioning member 21, the connecting end portions 231 of the slats 23 are in a positional relationship such that they are close to each other. As shown in FIGS. 20 becomes a contracted state (contracted state). At this time, since the annular connecting portion 221 of the interlocking member 22 is fitted to the rail 10, it can be moved smoothly.

  As described above, since the extendable door unit 20 is provided with the slats 23 and the shielding member 24, when the extendable door unit 20 is in the extended state, the chips and chips are confined in the inner side 102 of the cover opening 1, and cutting is performed. A shielding effect is provided to prevent the liquid from splashing, and the troublesome maintenance due to leakage of chips and the like can be reduced.

  The drive unit 30 in this embodiment has been described by taking a rodless cylinder as an example. However, the present invention is not limited to this, and the interlocking member 22 and the positioning member 21 may be moved closer to or away from each other. The drive unit 30 may employ a rod cylinder. In addition to the cylinder, this rod cylinder may be combined with a piston rod that can expand and contract along the first axial direction X with respect to the cylinder, and the end of the piston rod may be connected to an interlocking member (not shown). Absent. Further, the drive unit 30 may use a rack and pinion extended along the first axial direction X and a motor that moves the rack and pinion. Alternatively, the drive unit 30 may be a combination of a motor, a pulley, and a belt that can be positioned with respect to the cover opening 1.

  As described above, since the machine tool cover device of the present invention has a simple structure and an excellent effect, the object of the present invention can be achieved.
