[0029] In the present utility model, the machine tool body 3 is the bed structure of the machine tool, and the workbench is arranged on the machine tool body 3. The machine tool body 3 is provided with a beam 37 located on the upper side of the workbench, and a laser cutting head 38 is arranged on the beam 37. After the beam 37 slides to a predetermined position on the machine tool body 3, the laser cutting head 38 moves left and right along the beam 37 to a predetermined position, and the laser cutting head 38 cuts the plate on the workbench.

[0030] Here, the workbench is arranged on the machine tool body 3, and adopts a double-layer workbench structure, namely an upper workbench 1 and a lower workbench 2. The two-layer workbench structure can be exchanged in parallel.

The laser cutting head 38 cuts the plate on the lower workbench 2. At this time, the upper workbench 1 can be cooled and recovered or reloaded; similarly, when the lower workbench 2 finishes work, the lower workbench 2 is moved away, and the upper workbench 1 is moved back to work.

[0031] The machine tool body 3 includes two side wall panels 31 and a middle square tube 32 for connecting the two side wall panels 31. The side wall panels are welded together by plates and then welded as a whole by the middle square tube 32, so that the cutting area of ​​the machine tool body 3 is a hollow structure, and the accuracy of the bed will not be affected by the heat of the bed.

[0032] In addition, a driving chain 34 for driving the workbench to slide and a slide rail 33 for facilitating the sliding of the workbench are provided on the side wall panel 31; the driving chain 34 is connected with a driving gear and a driving machine for driving the driving gear to rotate, the upper workbench 1 and the lower workbench 2 are both connected to the driving chain 34, the driving chain 34 is located between the upper workbench 1 and the lower workbench 2, the driving chain 34 is a chain connected at the front and rear ends, so that the upper workbench 1 is connected to the upper side of the driving chain 34, and the lower workbench 2 is connected to the lower side of the driving chain 34, then when the driving chain 34 rotates and transmits, the upper workbench 1 and the lower workbench 2 are displaced in opposite directions, which just allows the upper workbench 1 and the lower workbench 2 to be exchanged in parallel.

[0033] Finally, the side wall panel 31 is provided with a tightening cylinder extending toward the workbench. When the upper workbench 1 and the lower workbench 2 are exchanged, the tightening cylinder on the side wall panel 31 extends out to press against the workbench 1 or the lower workbench 2, ensuring the stable use of the workbench, and loading on the rear workbench does not affect the stable cutting operation of the front workbench.
