Laser cutting is fast, producing smooth, flat cuts that generally require no further processing. It features a small heat-affected zone, minimal sheet deformation, and narrow kerf. The cut is free of mechanical stress and burrs. It boasts high processing precision, good repeatability, and no damage to the material surface. CNC programming allows for the processing of any planar shape, enabling the cutting of large sheets without the need for molds, saving time and money.

[0021] Reference Figures 1-4 A five-axis laser cutting machine, including Frame 1, with support platform 3 mounted on frame 1; A collection box 4 is slidably connected to the bottom of the front of the frame 1. All four corners of the bottom of the collection box 4 are equipped with casters, so that when the collection box 4 is pulled from the front of the frame 1, the collection box 4 can be detached from the frame 1 by the casters at the bottom, thereby cleaning the waste inside the collection box 4 after cutting. The three-axis moving module is installed on the support platform 3 and is used to adjust the position of the laser cutting head 8 along the X, Y and Z axes. The three-axis moving module includes a support platform 3, an X-axis module 5, a Y-axis module 6, and a Z-axis module 7. The outer side of the support platform 3 is fixed to the frame 1, thus supporting the X-axis module 5, Y-axis module 6, and Z-axis module 7 inside the frame 1. An X-axis module 5 is fixed to one side of the top of the support platform 3, allowing the X-axis module 5 to be supported from the bottom by the support platform 3, and positioning the X-axis module 5 on the top of the support platform 3 away from the upper sliding door 2. The Y-axis module 6 is located on top of the X-axis module 5, allowing the X-axis module 7 to move along the top of the support platform 3. The operation of the X-axis module 5 can drive the Y-axis module 6 to translate in the X-axis direction. One end of the Y-axis module 6 is provided with the Z-axis module 7, so that the operation of the Y-axis module 6 can drive the Z-axis module 7 to translate in the Y-axis direction. One side of the Z-axis module 7 is connected to the laser cutting head 8, and the operation of the Z-axis module 7 can realize the up and down adjustment of the laser cutting head 8 in the Z-axis direction. Thus, through the cooperation of the X-axis module 5, the Y-axis module 6 and the Z-axis module 7, the X-axis, Y-axis and Z-axis directions of the laser cutting head 8 can be adjusted. Laser cutting head 8, mounted on a three-axis moving module, is used for laser cutting of workpieces; A single-arm cradle 9 is mounted on a support platform 3 and is used to rotate the workpiece around the Y-axis or Z-axis. The single-arm cradle 9 includes a bracket 91, a geared motor 92, a rotary table 93, a support plate 94, and a turntable 95. The bottom of the bracket 91 is fixed to the frame 1, so that the bracket 91 is located on the top of the support platform 3 near the X-axis module 5, and the bracket 91 does not affect the operation of the X-axis module 5. The geared motor 92 is fixed on the side of the bracket 91 away from the X-axis module 5. The output end of the geared motor 92 is connected to the rotary table 93, so that the operation of the geared motor 92 can drive the rotary table 93 to rotate around the Y-axis. The support plate 94 is fixed to the bottom of one side of the rotary table 93, so that the rotation of the rotary table 93 drives the support plate 94 to rotate synchronously. The turntable 95 is rotatably connected to the top of the support plate 94. The bottom of the support plate 94 is fixed with a stepper motor 96, which drives the turntable 95 to rotate, so that the turntable 95 can drive the workpiece on the top to rotate. In this embodiment, a drive gear can be connected to the output end of the stepper motor 96, and a driven gear can be fixed on the outside of the turntable 95 and inside the support plate 94. The diameter of the drive gear is smaller than that of the driven gear, so that the rotation of the drive gear drives the meshing driven gear to rotate, and the driven gear drives the turntable 95 to rotate.

[0022] In this embodiment, vacuum holes are evenly distributed inside the turntable 95, so that when the workpiece is on top of the turntable 95, air can be drawn out to allow the turntable 95 to vacuum-adsorb the workpiece on top. In other embodiments, the turntable 95 can also be an electromagnet, which can be used to magnetically adsorb the workpiece on top when energized.

[0023] Preferably, both ends of the bottom of the rotary table 93 on the side away from the geared motor 92 are fixed with reinforcing ribs 97, and the bottom of the reinforcing ribs 97 is fixed to the support plate 94. This can increase the stability of the connection between the rotary table 93 and the support plate 94 through the reinforcing ribs 97. In other embodiments, the connection between the reinforcing ribs 97 and the rotary table 93 or the support plate 94 can be replaced with bolt connection, etc.

[0024] Preferably, a U-shaped feeding guide plate 10 is fixed inside the support platform 3 and at the bottom of the single-arm cradle 9, so that the waste from the laser cutting head 8 laser cutting the workpiece at the top of the single-arm cradle 9 can enter the collection box 4 through the U-shaped feeding guide plate 10. Rectangular grooves are evenly distributed inside one end of the U-shaped feeding guide plate 10 and at the bottom of the support platform 3, so that the gas flow and heat dissipation effects can be achieved through the rectangular grooves.

[0025] The upper frame 11 is mounted on the frame 1 and is used to support and protect the laser cutting head 8, the single-arm cradle 9 and the three-axis moving module.

[0026] The upper frame 11 is slidably connected to the front of the upper sliding door 2, which can be adjusted by sliding inside the upper frame 11. When the upper sliding door 2 rises inside the upper frame 11, the workpiece on the single-arm cradle 9 inside the upper frame 11 can be installed. When the upper sliding door 2 descends inside the upper frame 11, it prevents the workpiece debris from the five-axis cutting inside the upper frame 11 from splashing and injuring the workers.

[0027] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0028] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.

[0029] The operation of the five-axis laser cutting machine provided by this utility model is as follows: When in use, the workpiece is placed on top of the turntable 95, and then the upper sliding door 2 is pulled down to close the front of the upper frame 11. The upper sliding door 2 increases the safety of the worker when viewing the upper frame 11 from the front. When the workpiece is being cut, the X-axis module 5, Y-axis module 6, or Z-axis module 7 can be used to move the laser cutting head 8 in the X, Y, and Z directions, thereby adjusting the laser cutting head 8 in three directions. At the same time, according to the processing requirements, the rotary table 93 can be driven to rotate by the operation of the reduction motor 92. The rotary table 93 drives the turntable 95 to rotate around the Y-axis direction through the support plate 94. The turntable 95 can also be driven to rotate on the top of the support plate 94 by the operation of the stepper motor 96, thereby achieving five-axis laser cutting of the workpiece. The laser cutting waste is then collected inside the collection box 4 through the U-shaped feeding guide plate 10.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
