AI Technical Summary
In existing laser cutting equipment, long-span guide rails deform due to thermal expansion and contraction, affecting cutting accuracy.
Two sets of support components are used, including a horizontally arranged first guide rail, a crossbeam, and second and third guide rails. Expansion gaps are maintained between each unit rail, and the second and third unit rails are staggered to guide the slide blocks, ensuring that the cutting head maintains a straight sliding trajectory when moving over a large span.
This effectively avoids bending deformation of the guide rail, ensuring a straight sliding trajectory of the cutting head during large-span movement, thereby improving processing accuracy.

[0047] For a better understanding of the present invention, the following will combine Figures 1 to 3 to detail the technical solution of the present invention:
[0048] The first motor (not shown in the figure) drives the first gear (not shown in the figure) to rotate, and since the first gear (not shown in the figure) and the first rack 112 are engaged with each other, the rotating first gear (not shown in the figure) can drive the cross beam 210 to slide along the first guide rail 110.

Since the expansion gaps are reserved between each second unit rail 221 and each third unit rail 231, the second unit rail 221 and the third unit rail 231 can expand and deform along the length direction, so as to avoid the bending deformation of the second unit rail 221 and the third unit rail 231. Since the third unit rails 231 and the second unit rails 221 are arranged in a staggered manner, when the sliding seat 310 passes through the expansion gap of the second unit rail 221, the third unit rail 231 can guide the sliding seat 310. When the sliding seat 310 passes through the expansion gap of the third unit rail 231, the second unit rail 221 can guide the sliding seat 310. Therefore, the cutting head 320 still has a straight sliding track during the large-span movement, so as to ensure the machining quality of the workpiece.
