[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0023] A crossbeam for a three-dimensional five-axis laser cutting machine, such as Figure 1 and Figure 2 It includes a crossbeam 1 and two slide rails 2 horizontally arranged on the front side of the crossbeam 1 along the length of the crossbeam 1. Mounting plates 3 are horizontally slidably connected to the two slide rails 2, and a cutting mechanism 4 is provided on the side of the mounting plate 3 away from the slide rails 2. A cover for covering the slide rails 2 is provided on the crossbeam 1.

[0024] like Figure 1 and Figure 2By covering the slide rail 2 with a cover, the occurrence of dust falling onto the slide rail 2 and affecting the operation of the cutting mechanism 4 can be reduced. When the mounting plate 3 slides on the slide rail 2, the cover and the mounting plate 3 do not affect each other.

[0025] The cutting mechanism 4 can be a laser cutting machine in the beam structure of a fiber laser cutting machine according to application number CN202323490454.5, which will not be described in detail here.

[0026] like Figure 2 and Figure 3 The cover includes a fixed box 5 arranged along the length of the crossbeam 1 on the front side of the crossbeam 1, and the opening of the fixed box 5 is located on the side of the fixed box 5 away from the crossbeam 1. Both slide rails 2 are arranged at the bottom of the fixed box 5. The end of the mounting plate 3 that is slidably connected to the slide rail 2 is located inside the fixed box 5. The fixed box 5 is provided with a sealing member for closing the opening of the fixed box 5.

[0027] like Figure 2 and Figure 3 By sealing the opening of the fixing box 5 with the sealing component, a closed space is formed inside the fixing box 5. This reduces the occurrence of dust entering the fixing box 5 and accumulating on the slide rail 2. The mounting plate 3 slides along the length of the slide rail 2 inside the fixing box 5, and the sealing component does not affect the sliding of the mounting plate 3.

[0028] like Figure 2 and Figure 3 and Figure 4 The crossbeam 1 has a square tube structure. The enclosure includes U-shaped fixing frames 6 installed on the left and right sides of the fixed box 5. The fixing frames 6 are rotatably connected to the opposite sides of the fixing frames 6. The end of the crossbeam 1 near the two fixing frames 6 is provided with a first connecting groove 8 that communicates with the crossbeam 1. The two rotating shafts 7 are connected by a conveyor belt 9. At this time, the fixed box 5 is located inside the conveyor belt 9, and the conveyor belt 9 closes the opening of the fixed box 5. The conveyor belt 9 on the side of the two rotating shafts away from the opening of the fixed box 5 is located inside the crossbeam 1 through the two first connecting grooves 8. The end of the conveyor belt 9 near the mounting plate 3 is provided with a rectangular groove 10. The end of the mounting plate 3 used to install the cutting mechanism 4 passes through the rectangular groove 10, and the mounting plate 3 is detachably connected to the groove wall of the rectangular groove 10.

[0029] like Figure 2 and Figure 3 and Figure 4 The conveyor belt 9 can seal the opening of the fixed box 5, forming a closed space inside the fixed box 5. When the mounting plate 3 slides on the slide rail 2, the mounting plate 3 will drive the two rotating shafts 7 to rotate through the conveyor belt 9. At this time, the conveyor belt 9 will always keep the opening of the fixed box 5 closed, thereby reducing the occurrence of dust entering the fixed box 5 and accumulating on the slide rail 2.

[0030] like Figure 2 and Figure 4 A rectangular frame 12 is installed on one side of the opening of the fixed box 5. Notches 13 are provided on both sides of the rectangular frame 12 near the conveyor belt 9 to cooperate with the conveyor belt 9. Baffles 14 are horizontally provided at the upper and lower ends of the inner wall of the rectangular frame 12. The baffles 14 are located outside the conveyor belt 9 and are in contact with the conveyor belt 9. The mounting plate 3 passes through the rectangular groove 10 and passes between the two baffles 14. The purpose of this setting is to restrict the position of the conveyor belt 9 at the opening of the fixed box 5 through the rectangular frame 12 and the notches 13 on the rectangular frame 12. At the same time, the two baffles 14 ensure that the conveyor belt 9 at the opening of the fixed box 5 is always in contact with the opening of the fixed box 5. Through the cooperation of the rectangular frame 12, the notches 13 on the rectangular frame 12 and the two baffles 14, the mounting plate 3 can keep the conveyor belt 9 closed when it drives the two rotating shafts 7 to rotate through the conveyor belt 9. It is simple and convenient to use.

[0031] like Figure 2 The top of the crossbeam 1 has several first slots 15 that penetrate the crossbeam 1, and the side of the crossbeam 1 away from the fixing box 5 has several second slots 16. The purpose of this arrangement is to reduce the weight of the crossbeam 1 through the first slots 15 and the second slots 16, so that the crossbeam 1 is lightweight.

[0032] like Figure 2 and Figure 3 and Figure 4 The bottom of the fixed box 5 is equipped with a rack 17, which is horizontally located between two slide rails 2. The mounting plate 3 is equipped with a motor 18, and one end of the rotating shaft of the motor 18 passes through the mounting plate 3 and is equipped with a gear 19 that meshes with the rack 17. The motor 18 is located on one side of the cutting mechanism 4. When the motor 18 is turned on, the rotating shaft of the motor 18 drives the gear 19 to rotate. Since the gear 19 meshes with the rack 17 and the rack 17 is located at the bottom of the fixed box 5, when the rotating shaft of the motor 18 drives the gear 19 to rotate, the mounting plate 3 can slide along the length of the slide rail 2 through the cooperation of the gear 19 and the rack 17. At the same time, since the gear 19 and the rack 17 are both located inside the fixed box 5, the conveyor belt 9 can close the opening of the fixed box 5 to reduce the accumulation of dust on the gear 19 and the rack 17, which would affect the operation of the gear 19 and the rack 17.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
