Therefore, in view of the above problems, the present application proposes the following three embodiments.

[0032] Example 1

[0033] This embodiment discloses a drag chain assembly, please refer to Figures 1 to 3 As shown, the drag chain assembly includes a drag chain mechanism and a line dividing mechanism, wherein:

[0034] The drag chain mechanism includes a first drag chain 10. The first drag chain 10 shown in the figure is only a schematic diagram of the structure. The actual structure is a chain link structure having multiple hinged links in sequence. The first drag chain 10 includes a first fixed end 11 for installation and fixation and a first swing end 12 swinging along a predetermined direction. A first through hole for accommodating a cable is formed inside the first drag chain 10.

[0035] The wire dividing mechanism includes a first frame 20, which has a first wire inlet 21 and a first wire outlet 22. The first wire inlet 21 is connected to the first swing end 12, and a first wire threading channel 23 is provided between the first wire inlet 21 and the first wire outlet 22.

[0045] The drag chain mechanism includes a first drag chain 10. The first drag chain 10 shown in the figure is only a schematic diagram of the structure. The actual structure is a chain link structure having multiple hinged links in sequence. The first drag chain 10 includes a first fixed end 11 for installation and fixation and a first swing end 12 swinging along a predetermined direction. A first through hole for accommodating a cable is formed inside the first drag chain 10.

When the driving end of the x-axis driving device is driven along the x-direction, the first frame 20 drives the first swinging end 12 of the first drag chain 10 to swing along the x-direction.

[0050] For large laser cutting machines, due to the large number of cables, water pipes, oil pipes, etc., the entry positions and entry angles are different. If the second cable inlet 32 ​​has only one unified cable inlet, some cables need to detour a longer distance. Therefore, this embodiment makes corresponding openings for cables entering at different angles, and sets at least one second cable inlet 32 ​​on different sides of the second frame 30, so that the cables can enter directly, without having to detour a long distance ineffectively, thereby simplifying the structure and reducing the cable cost.
