Description

Technical Field

[0001] This utility model relates to the field of fiber laser cutting technology, specifically to a fiber laser cutting machine. Background Technology

[0002] Fiber laser cutting machines utilize fiber laser generators as their light source. Fiber lasers are a newly developed type of laser internationally, capable of outputting high-energy-density laser beams that are focused onto the workpiece surface. This causes the area irradiated by the ultra-fine focal spot to melt and vaporize instantly. Automatic cutting is achieved by moving the spot's irradiation position using a CNC mechanical system. Compared to bulky gas lasers and solid-state lasers, fiber lasers offer significant advantages and have gradually become a key candidate in high-precision laser processing, lidar systems, space technology, and laser medicine.

[0003] Existing fiber laser cutting machines can only be operated manually by feeding the workpiece, and the fiber laser head cannot move in all directions, resulting in blind spots during the cutting process. This leads to inconvenience in using the fiber laser cutting machine and greatly reduces its practicality. Utility Model Content

The two first sliding grooves are slidably connected to the corresponding X-axis guide rails. The bottom of the connecting plate is symmetrically provided with second sliding grooves, and the two second sliding grooves are slidably connected to the two Z-axis guide rails one-to-one.

[0010] As a further improvement to this technical solution, the third drive assembly includes two first racks symmetrically arranged on the top of the working base frame. Two synchronous motors are respectively mounted on the two brackets, and the shafts of the two synchronous motors are connected to the first gears. The two first gears mesh with the corresponding first racks.

[0011] As a further improvement to this technical solution, the second drive assembly includes a second drive motor disposed on the top of a connecting plate. The shaft of the second drive motor passes through the connecting plate and is connected to a second gear. The second gear meshes with a second rack.

Two X-axis guide rails 11 are symmetrically arranged on both sides of the top of the working base frame 1. The same crossbar 10 is slidably arranged on the two X-axis guide rails 11. The connection between the rail 11 and the crossbar 10 is provided with a third drive assembly 7 that synchronously drives the crossbar 10 to slide.

The bottom of the gathering groove 15 is connected to the receiving box 16 through a discharge port. The receiving box 16 is movably connected to the bottom of the gathering groove 15.

[0028] During operation, the workpiece to be processed is placed on the feeding carrier plate 4, and the first drive component 5 is controlled to drive the feeding carrier plate 4 to move towards the working platform 3.

[0030] In this embodiment, as Figures 1-5 As shown, the first drive assembly 5 also includes a first drive motor 504 located in the middle of the side of the working base 1 away from the feeding base 2. The rotating shaft of the first drive motor 504 is connected to the output shafts 505 on both sides through the transmission assembly 506. The two output shafts 505 are respectively connected to the corresponding drive gears 503.

[0031] Specifically, during operation, the first drive motor 504 starts and drives the output shafts 505 on both sides to rotate through the transmission components 506 such as gears or belts. The output shafts 505 drive the corresponding drive gears 503 to rotate, causing the transmission chain 502 to move between the drive gears 503 and the driven gears 501. This causes the feeding plate 4 and the working platform 3 connected to the transmission chain 502 to move horizontally, and at the same time, it causes the feeding plate 4 and the working platform 3 to move relative to or away from each other.

[0032] In this embodiment, as Figures 1-5 As shown, the working base frame 1 and the feeding base frame 2 are respectively mounted on the first guide rail 18 above the two transmission chains 502, and the bottom sides of the feeding plate 4 are slidably connected to the corresponding first guide rail 18 by the first rollers 19.

The two first gears 703 mesh with the corresponding first racks 701.

[0041] Specifically, during operation, two synchronous motors 702 are started simultaneously, and the two synchronous motors 702 drive the corresponding first gear 703 to rotate. Since the first rack 701 meshing with the first gear 703 is fixedly set on the top of the working base 1, it drives the two supports 22 to move relative to the working base 1, thereby driving the crossbar 10 to move above the working platform 3.

[0042] In this embodiment, as Figure 1 and Figure 2 As shown, the second drive assembly 6 includes a second drive motor 601 with a connecting plate 13 on top.

[0043] Specifically, during operation, the second drive motor 601 is started, which drives the second gear 602 to rotate. Since the second rack 603, which meshes with the second gear 602, is fixedly mounted on the crossbar 10, it drives the connecting plate 13 to move relative to the crossbar 10, thereby driving the fiber laser head 9 to move above the working platform 3.

[0045] Specifically, during operation, the piston of cylinder 802 extends and retracts, driving slider 803 to move up and down on Y-axis guide rail 801, thereby driving fiber laser head 9 to move up and down.

[0046] In this embodiment, as Figure 3 and Figure 4 As shown, the receiving box 16 has two sets, each set of receiving boxes 16 is connected to two sets of gathering slots 15, and the receiving box 16 is located on the side near the feeding base frame 2 and is connected to a pull rod 25.
