Description

Technical Field

[0001] This utility model relates to the field of laser cutting, and in particular to a large-format three-dimensional five-axis laser cutting machine rotary table and laser cutting machine. Background Technology

[0002] Today, 3D five-axis laser cutting machines are widely used in industries such as automotive thermoforming and aerospace. A dual-station rotary table is a crucial component, allowing the machine to cut internal workpieces while simultaneously loading and unloading external workpieces. Previously, laser cutting machines primarily had X and Y axis travel of 3 meters x 1.5 meters. However, with the emergence of demand for cutting integrated automotive door rings, laser cutting machines with X and Y axis travel exceeding 4 meters x 2.5 meters have become necessary, requiring a corresponding increase in the rotary table's width. However, this increased width reduces rigidity, causing significant vibration during external loading and unloading, which negatively impacts the processing of internal workpieces.

[0003] The existing solution is to reduce the impact force when loading and unloading externally, but this will cause the workpiece to be placed unevenly or not in the correct position, affecting the cutting. Alternatively, loading and unloading can be done after the internal cutting is completed, which will affect the processing efficiency.

[0004] Therefore, it is necessary to design a new rotary table for a large-format three-dimensional five-axis laser cutting machine to overcome the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] like Figures 1-5This utility model provides a large-format three-dimensional five-axis laser cutting machine rotary table, including a steel rotary platform 1 and a turntable 5 that drives the rotary platform 1 to rotate. In this embodiment, the turntable 5 is a cam-type turntable. The rotary platform 1 is formed by a top plate 8, a bottom plate 9 and side walls. The rotary platform 1 is provided with a cross-shaped rib plate 10 inside. The bottom plate 9 of the rotary platform is installed on the turntable 5.

Clamps are installed on the support arms 3, and the workpiece to be cut is clamped on the clamps. The support arms 3 and their corresponding rotary platform side walls are also connected by inclined connecting rods 4, which act as diagonal supports.

[0030] In this embodiment, the rotating platform 1 is rectangular. Two support arms 3 are provided on each of the two opposite side walls of the rotating platform 1, and the two support arms 3 are spaced apart.

[0031] In this embodiment, the top plate, bottom plate, and side walls of the rotating platform 1 are all made of steel plates, with the bottom plate and side walls using steel plates 25mm to 30mm thick. The steel plates are connected by full welding, and the herringbone-shaped stiffening plates 10 are connected to the inner wall of the rotating platform 1 by intermittent welding, ensuring overall rigidity while improving vibration resistance. In this embodiment, the two side walls of the rotating platform mounting arm 3 adopt a double-layer stiffening plate structure, which further improves the overall vibration resistance.

[0032] In this embodiment, a cylindrical steel pipe 11 for wiring is provided in the middle of the rotating platform 1. The cylindrical steel pipe 11 increases the overall rigidity while serving as a wiring conduit.

[0033] In this embodiment, several hollow holes are provided on the cross-shaped stiffener 10 and the base plate 9 of the rotating platform, which reduces the overall weight of the rotating platform while ensuring rigidity.

[0034] This utility model provides a laser cutting machine in embodiment two, including a laser protective chamber, a machine tool frame, a laser cutting head, an XYZ three-axis platform for driving the laser cutting head, and the aforementioned large-format three-dimensional five-axis laser cutting machine rotary table.

The machine tool frame is located inside the laser protective chamber. One side support arm 3 of the rotary platform 1 is located inside the laser protective chamber, and the other side support arm 3 of the rotary platform 1 is located outside the laser protective chamber. The large-format three-dimensional five-axis laser cutting machine rotary table provided by this utility model is a dual-station rotary table. When the support arm 3 on one side of the rotary platform 1 feeds the workpiece to be cut into the laser protective chamber for laser cutting, the other side support arm 3 of the rotary platform 1 loads and unloads the workpiece outside the laser protective chamber. The large-format three-dimensional five-axis laser cutting machine rotary table provided by this utility model has a high-rigidity large-format rotary table platform, ensuring the cutting quality of the internal workpiece when loading and unloading is done outside the rotary table.

The external dimensions of the rotating platform 1 are 2700mm long × 1350mm wide × 210mm high. The material can be Q235-A steel plate, or 16Mn or Q345-B high-strength steel. The four side walls and the base plate of the rotating platform 1 are welded from steel plates with a thickness of 25mm to 30mm. Figure 5 The rotating platform 1 features internal herringbone ribs 10, with a cylindrical steel pipe 11 in the center to increase overall rigidity. The hollow interior of the cylindrical steel pipe 11 can be used for cable routing. The two side walls of the mounting arms 3 employ a double-layer rib structure to improve overall vibration resistance. Several rectangular holes are formed in the herringbone ribs 10 inside the rotating platform, and several triangular holes are formed in the base plate 9, ensuring rigidity while reducing the overall weight of the rotating platform. The external steel plates (between the top plate 8, base plate 9, and side walls) are fully welded, while the internal herringbone ribs 10 are intermittently welded to the inner wall of the rotating platform 1, ensuring overall rigidity and improving vibration resistance.
