Abstract

(57) [Summary] [Purpose] To provide a machine tool that can easily place a long work on a table and requires a small floor area. [Structure] A strip-shaped member is foldably connected, and a door having a guide member provided on one or both of the upper and lower sides of the center of each member and a rail are provided, and the door is engaged with the rail.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cover for a machine tool.

[0002]

[Prior art]

 In machine tools, a cover is placed around the table on which the work is placed in order to prevent cutting fluid and chips from scattering around the machine. ◆ Fig. 5 is a front view showing an example of a conventional machine tool, in which 1 is a fixed cover and 2 is two doors. When the work is placed on the internal table, the door 2 closed in the figure is moved to the left and right to the position indicated by the chain double-dashed line to form a passage to the inside.

[0003]

[Problems to be solved by the device]

 However, assuming that the width of the front surface of the cover surrounding the table is W, the maximum frontage obtained by moving the door 2 is W / 2. For this reason, a crane or the like had to be used when placing a work longer than W / 2 on the internal table, and workability was low. An object of the present invention is to solve the above-mentioned problems and to provide a machine tool which can easily place a work longer than W / 2 on a table and requires a small floor area.

[0004]

[Means for Solving the Problems]

 The above-mentioned problem is provided with a door in which strip-shaped members are foldably connected and a guide member is provided at one or both of the upper and lower sides of the center of each member, and a rail, and the door is provided in the rail. It is solved by engaging.

[0005]

[Action]

 By setting the relation between the width B and the thickness t of the strip-shaped member as B >> t, the frontage can be increased.

[0006]

【Example】

 1 is a front view of a cover of a machine tool showing an embodiment of the present invention, FIG. 2 is a plan view, FIG. 3 is an enlarged view of an end portion taken along the line AA of FIG. 1, and FIG. 4 is a line BB of FIG. FIG. ◆ In the figure, 3 is a table. A strip-shaped cover member 5 has a connecting member 6 fixed to the end portion. The width and thickness of the cover member 5 are B and t, respectively. Reference numeral 7 is a hinge that connects adjacent cover members 5 via connecting members 6. The hinge 7a is arranged on the upper side in FIG. 2, and the hinge 7b is arranged on the lower side in FIG. A caster 8 is arranged below the center of the cover member 5, and is composed of a holder 9 and a ball 10. Reference numeral 11 denotes a rail, which has a groove 12 for guiding the casters 8. It should be noted that there is almost no gap between the lower end of the cover member 5 and the upper end of the rail 11. A rotatable cover 14 is provided at the end of the fixed cover 13, and the cover member 5 is connected to the fixed cover 13 via the cover 14. With the above configuration, when the cover member 5 is moved in the state of FIG. 1, for example, the cover member 5 moves while rotating around the ball 10 and becomes a flat door at the moving end. When opening the door, move it in the opposite direction. In addition, although the rail 11 is one in this embodiment, it may be arranged vertically. Further, if only the cover member 5 adjacent to the fixed cover 13 is supported by the rotating shaft which does not move left and right instead of the caster 8, the cover 14 may not be provided.

[0007]

[Effect of device]

 As described above, according to the present invention, it is possible to easily place a long work on the table and to reduce the installation floor area. ◆
