(Example) Hereinafter, an example according to the present invention will be described based on the drawings.

Referring to FIGS. 1, 2, 3, and 4, the laser processing machine 1 includes a frame 7 in which an upper frame 3 and a lower frame 5 are vertically opposed. is configured in a C-shape. Note that the frame 7 may be configured in a bridge type.

A workpiece is supported on the front side of the lower frame 5 (the left side in Figures 1 and 2, the front side when facing the page in Figure 3, and the back side when facing the page in Figure 4). A work table 9 is provided for this purpose. That is, the work table 9 includes a fixed table 11 fixedly provided to the lower frame 5, and the left and right sides of this fixed table 11 (top and bottom in FIG. 1, front and back facing the paper in FIG. 2, It consists of a pair of movable tables 13 and 15 placed on both sides (left and right in the figure). Above movable table 1
3.15 is movable in the front and rear directions via rails 17 provided on the lower frame 5.

In order to move and position the work supported on the work table 9, a moving positioning device 1 is attached to the work table 9.
9 is the setting. That is, a pair of movable tables 1.3
．． 15 is integrally provided with a gear ledge base 21 extending in the left-right direction, and this gear ledge base 21 includes:
A carriage 25 equipped with a clamp device 23 for gripping a workpiece is provided so as to be movable in the left-right direction.

Therefore, after the work supported on the work table 9 is gripped by the clamp device 23, the movable table 13
．． By integrally moving the gear ledge base 21 in the front-rear direction and moving the carriage 25 in the left-right direction, the workpiece can be moved appropriately on the work table 9 in the front-rear and left-right directions. be.

A laser processing head 27 is provided on the upper frame 3 in order to irradiate the workpiece supported on the worktable 9 with laser light and eject assist gas.

A laser oscillator 31 optically connected to the laser processing head 27 via a pend mirror 29 or the like is provided on the upper side of the upper frame 3 via a suitable vibration-proofing structure. Further, a power supply device 33 for operating the laser oscillator 31 is provided on the side of the first space 35 regulated by two directions: the rear of the movable table 13 and the left side of the lower frame 5.

Further, an NC device 37 for NC-controlling other components of the laser processing machine 1 such as the moving positioning device 19 is located in a second space 3 regulated by two directions: the rear of the movable table 15 and the right side of the lower frame 5. It is placed on one side.

The operation of this embodiment will be explained based on the above-described configuration.

The workpiece supported on the worktable 9 is clamped by the clamping device 2
