Abstract

A vertical machining center includes a base; a tilting rotary table, a tool spindle, a tilting shaft, a recessed area, a slide door, and an inner cover. The tilting rotary table is disposed on the base and configured to turn and tilt a table face of a rotary table. The tool spindle is rotatable about a vertical axis line and movable in an X axis direction, a Y axis direction, and a Z axis direction. The tilting shaft is disposed in the tilting rotary table and oriented in the Y axis direction. The recessed area is disposed on a front surface of the vertical machining center. The recessed area is adjacent to a support supporting the tilting shaft. The slide door is configured to cover the front surface. The inner cover is integral with the slide door. The inner cover is configured to cover the recessed area.

First claim

What is claimed as new and desired to be secured by Letters Patent of the United States is:

1 . A vertical machining center comprising:
a base; a tilting rotary table disposed on the base and configured to turn and tilt a table face of a rotary table; a tool spindle rotatable about a vertical axis line and movable in an X axis direction, which is a right-left direction of the vertical machining center, in a Y axis direction, which is a front-rear direction of the vertical machining center, and in a Z axis direction, which is vertical direction, the X axis direction, the Y axis direction, and the Z axis direction being orthogonal to each other; a tilting shaft disposed in the tilting rotary table and oriented in the Y axis direction; a recessed area disposed on a front surface of the vertical machining center, the recessed area being adjacent to a support supporting the tilting shaft; a slide door configured to cover the front surface of the vertical machining center in a manner that is openable and closable; and an inner cover integral with the slide door and configured to cover the recessed area.

2 . The vertical machining center according to claim 1 , wherein the recessed area comprises a distal end approximately on an extended line of a front end of the rotary table.

3 . The vertical machining center according to claim 1 , wherein the slide door is configured to slide into a fixed cover disposed on the front surface of the vertical machining center, and an operation panel is mounted to an end of the fixed cover, the end of the fixed cover being adjacent to the recessed area, the operation panel being configured to turn to be fixed at any position between positions parallel and orthogonal to the fixed cover.

4 . The vertical machining center according to claim 1 , wherein the inner cover has an upper end fixed to an inner surface of the slide door and a lower end engaged with a rail mounted to the base.

5 . The vertical machining center according to claim 1 , wherein the slide door comprises two slide doors.

6 . The vertical machining center according to claim 5 , wherein the two slide doors are configured to respectively open to a left and a right with a part of an end of the recessed area adjacent to the rotary table being a center of opening.

7 . The vertical machining center according to claim 6 , wherein one slide door among the two slide doors comprises the inner cover on an inner surface of the one slide door.

8 . The vertical machining center according to claim 7 , further comprising a door meshing member disposed between the two slide doors, the door meshing member comprising a labyrinth mechanism.

9 . The vertical machining center according to claim 2 , wherein the slide door is configured to slide into a fixed cover disposed on the front surface of the vertical machining center, and an operation panel is mounted to an end of the fixed cover, the end of the fixed cover being adjacent to the recessed area, the operation panel being configured to turn to be fixed at any position between positions parallel and orthogonal to the fixed cover.

10 . The vertical machining center according to claim 2 , wherein the inner cover has an upper end fixed to an inner surface of the slide door, and has a lower end engaged with a rail mounted to the base.

11 . The vertical machining center according to claim 3 , wherein the inner cover has an upper end fixed to an inner surface of the slide door, and has a lower end engaged with a rail mounted to the base.

12 . The vertical machining center according to claim 9 , wherein the inner cover has an upper end fixed to an inner surface of the slide door, and has a lower end engaged with a rail mounted to the base.

13 . The vertical machining center according to claim 2 , wherein the slide door comprises two slide doors.

14 . The vertical machining center according to claim 3 , wherein the slide door comprises two slide doors.

15 . The vertical machining center according to claim 4 , wherein the slide door comprises two slide doors.

16 . The vertical machining center according to claim 9 , wherein the slide door comprises two slide doors.

17 . The vertical machining center according to claim 10 , wherein the slide door comprises two slide doors.

18 . The vertical machining center according to claim 11 , wherein the slide door comprises two slide doors.

19 . The vertical machining center according to claim 12 , wherein the slide door comprises two slide doors.

20 . The vertical machining center according to claim 13 , wherein the two slide doors are configured to respectively open to a left and a right with a part of an end of the recessed area adjacent to the rotary table being a center of opening.

21 . A vertical machining center comprising:
a tool spindle rotatable about an axis extending in a first direction; a base supporting the tool spindle and including a recessed part viewed along the first direction; a tilting rotary table disposed on the base and having a table face on which a work to be processed via the tool spindle is to be placed; a shaft having a shaft axis which extends in a second direction orthogonal to the first direction and around which the table face tilts; and a support supporting the shaft, the recessed part being adjacent to the support.

22 . A vertical machining center comprising:
a tool spindle rotatable about an axis extending in a first direction; a base supporting the tool spindle and including a recessed part viewed along the first direction; a tilting rotary table disposed on the base and having a table face on which a work to be processed via the tool spindle is to be placed; a shaft having a shaft axis which extends in a second direction orthogonal to the first direction and around which the table face tilts; and a support supporting the shaft, the recessed part including a bottom part and a side part connecting to the bottom part viewed along the first direction, the side part facing the support viewed along the first direction.
