[0002] Laser beveling technology is widely used in industries such as shipbuilding, steel structure processing, aerospace, bridge manufacturing, and large machinery manufacturing due to its high precision, high efficiency, and high degree of automation.

[0003] Currently, most laser beveling equipment on the market adopts a single beam structure. When facing working conditions such as large span, high load, and high speed, the traditional beam structure is mostly a single-layer closed frame or a simple steel plate welded structure. Under stress, it is prone to bending deformation, resulting in cutting path deviation and affecting processing accuracy. In addition, under large span conditions, the beam itself is heavy and is prone to local deformation due to gravity, reducing the long-term operating stability of the equipment. Summary of the Invention

[0004] Therefore, this utility model provides a large-span crossbeam structure for laser beveling and marking. By optimizing the crossbeam design, it effectively improves the operating accuracy, stability and service life of the equipment, meeting the application needs of large-span and high-precision processing scenarios.

[0005] To solve the above-mentioned technical problems, this utility model provides a large-span crossbeam structure for laser beveling and marking, comprising:

[0006] The crossbeam body includes a first crossbeam and a second crossbeam arranged in parallel, and a plurality of longitudinal connecting frames connecting the first crossbeam and the second crossbeam. The first crossbeam and the second crossbeam each include a hollow outer frame arranged along their length direction and a hollow inner frame located within the hollow outer frame. A plurality of stiffening plates are provided between the hollow outer frame and the hollow inner frame. A cover plate is provided between the end faces of the hollow outer frame and the hollow inner frame along their respective length direction. A flat plate is laid between the upper ends of two adjacent longitudinal connecting frames, and the plurality of flat plates are connected sequentially.

[0007] A mounting bracket is installed on the second crossbeam, and the mounting bracket is provided with a linear guide rail and a rack extending along the length direction of the crossbeam body;

[0008] The cutting and scribing mechanism includes a movable frame connected to the linear guide rail. The movable frame is equipped with a laser beveling device, a scribing device, and a moving drive mechanism. The moving drive mechanism includes a reducer connected to the movable frame and a servo motor connected to the reducer. The output end of the reducer is connected to a drive gear that meshes with the rack.

[0009] In one embodiment of this utility model, the first crossbeam and the second crossbeam are provided with mounting plates on their opposite sides, and the two ends of the longitudinal connecting frame are mounted on the mounting plates by bolts.

[0010] In one embodiment of this utility model, the top end of the second crossbeam is provided with a cable chain groove and a cable chain.

[0011] In one embodiment of this utility model, a limit bracket is provided on the second crossbeam on the same side as the linear guide rail.

[0012] In one embodiment of this utility model, two linear guide rails are arranged in parallel and located on the upper and lower sides of the second crossbeam.

[0013] In one embodiment of this utility model, a first lifting device and a second lifting device are further included; the first lifting device is installed on the mobile frame and its driving end is connected to the laser beveling device; the second lifting device is installed on the mobile frame and its driving end is connected to the scribing device.

[0014] In one embodiment of this utility model, a balancing mechanism is also included. The laser beveling device has an auxiliary pipeline including a cable, an air pipe, and a water pipe. The balancing mechanism is mounted on the mobile frame and is used to lift the auxiliary pipeline.

[0016] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0017] This utility model describes a large-span crossbeam structure for laser beveling and marking. By employing a double-beam structure with a first and second crossbeam, it significantly improves rigidity compared to a single-beam structure, preventing deformation caused by the large span and improving processing accuracy. The combined design of a hollow outer frame, a hollow inner frame, and stiffening plates reduces the crossbeam's self-weight while enhancing the overall structural strength and load-bearing capacity. Longitudinal connecting frames provide lateral support, ensuring minimal deformation of the crossbeam during prolonged operation and improving operational stability. The enclosed end-face cover design enhances overall protection, preventing dust and metal debris from entering the crossbeam and avoiding the influence of the external environment.

[0018] This invention integrates a laser beveling and scribing device onto a single machine via a movable frame, enabling both cutting and scribing to be completed, reducing steps and improving efficiency. A balancing mechanism minimizes the swaying of the auxiliary pipeline during cutting, reducing its impact on cutting accuracy. Attached Figure Description

[0034] Reference Figures 1 to 6 As shown, this utility model discloses a large-span crossbeam structure for laser beveling and marking, comprising:

[0035] The crossbeam body 1 includes a first crossbeam 11a and a second crossbeam 11b arranged in parallel, and a plurality of longitudinal connecting frames 12 connecting the first crossbeam 11a and the second crossbeam 11b. The first crossbeam 11a and the second crossbeam 11b each include a hollow outer frame 111 arranged along its length direction and a hollow inner frame 112 located inside the hollow outer frame 111. A plurality of stiffening plates 113 are arranged between the hollow outer frame 111 and the hollow inner frame 112. A cover plate 114 is arranged between the end faces of the hollow outer frame 111 and the hollow inner frame 112 in their respective length directions. A flat plate 13 is laid between the upper ends of two adjacent longitudinal connecting frames 12, and a plurality of flat plates 13 are connected in sequence.

[0036] Mounting bracket 2 is mounted on the second crossbeam 11b. The mounting bracket 2 is provided with a linear guide rail 21 and a rack 22 extending along the length direction of the crossbeam body 1.

[0037] The cutting and scribing mechanism 3 includes a movable frame 31 connected to the linear guide rail 21. The movable frame 31 is equipped with a laser beveling device 32, a scribing device 33, and a moving drive mechanism 34. The moving drive mechanism 34 includes a reducer 341 connected to the movable frame 31 and a servo motor 342 connected to the reducer 341. The output end of the reducer 341 is connected to a drive gear 343 that meshes with the rack 22.

[0038] By employing a double-beam structure with a first crossbeam 11a and a second crossbeam 11b, rigidity is significantly improved compared to a single-beam structure, avoiding deformation caused by large spans and improving processing accuracy. The combined design of the hollow outer frame 111, the hollow inner frame 112, and the stiffening plate 113 reduces the self-weight of the crossbeam while enhancing the overall structural strength and load-bearing capacity. The longitudinal connecting frame 12 provides lateral support, ensuring that the crossbeam maintains minimal deformation during long-term operation and improving operational stability. The enclosed design of the end cover plate 114 enhances overall protection, preventing dust and metal debris from entering the crossbeam and avoiding the influence of the external environment on the crossbeam.

[0039] In one embodiment, refer to Figure 2 As shown, mounting plates 14 are provided on the opposite sides of the first crossbeam 11a and the second crossbeam 11b. The two ends of the longitudinal connecting frame 12 are bolted to the mounting plates 14 for easy maintenance and replacement of parts later.

[0040] In one embodiment, refer to Figure 3 As shown, the top of the second crossbeam 11b is provided with a cable chain groove 23 and a cable chain 24.

[0041] In one embodiment, refer to Figure 3 As shown, a limit bracket 15 is provided on the second crossbeam 11b on the same side as the linear guide rail 21. The limit bracket 15 restricts the maximum stroke of the moving frame 31, reducing the risk of equipment damage.

[0042] In one embodiment, refer to Figure 3 As shown, two linear guide rails 21 are arranged in parallel and located on the upper and lower sides of the second crossbeam 11b. This provides bidirectional support, ensuring that the cutting and scribing device 33 maintains a stable trajectory even during high-speed operation, preventing swaying or track deviation.

[0043] In one embodiment, refer to Figure 4 , Figure 5As shown, it also includes a first lifting device 35 and a second lifting device 36; the first lifting device 35 is installed on the mobile frame 31 and its driving end is connected to the laser beveling device 32; the second lifting device 36 is installed on the mobile frame 31 and its driving end is connected to the scribing device 33.

[0044] The laser beveling device 32 and the scribing device 33 are integrated into the same equipment by using a movable frame 31, reducing processes and improving efficiency. A servo motor 342, a reducer 341, and a rack and pinion transmission 22 ensure high responsiveness and high precision of the equipment's movement.

[0045] The drive gear 343 meshes precisely with the rack 22, reducing motion errors, improving positioning accuracy, and ensuring cutting quality.

[0046] Understandably, the first lifting device 35 can control the height of the laser beveling device 32 to adapt to materials of different thicknesses, ensuring that the cutting focus is always in the optimal state and improving cutting quality. A linear module can be used, providing high motion precision and ensuring positional accuracy during the cutting process. The second lifting device 36 can independently adjust the height of the scribing device 33 to adapt to different workpieces and improve scribing accuracy; similarly, a linear module can be used.

[0047] Furthermore, since the laser of the laser beveling device 32 itself has many cables, air pipes, and water pipes, a balancing mechanism 37 is provided to prevent these cables, air pipes, and water pipes from swaying during laser cutting. In one embodiment, a balancing mechanism 37 is also included. The laser beveling device 32 has an auxiliary pipeline 321 extending from it, which includes cables, air pipes, and water pipes. The balancing mechanism 37 is mounted on the movable frame 31 and is used to lift the auxiliary pipeline 321. The balancing mechanism 37 includes a balancer 371 and connectors 372 that are connected to the balancer 371 and the auxiliary pipeline 321, respectively.

[0048] It should be noted that the balancer 371 is a mechanical device used to compensate for weight and reduce the effects of load inertia. The balancer 371 connects one end of the balance rope 375 to the clamping sleeve through a preset spring tension. Cables, air pipes and water pipes pass through and are clamped by the clamping sleeve. The balance rope 375 applies appropriate tension to the cables, air pipes and water pipes, keeping them in a suspended state so as not to drag the ground or affect the movement of the equipment.

[0049] In one embodiment, refer to Figure 6As shown, the balancing mechanism 37 also includes a support body 373 and a base 374. The base 374 is installed on the top of the mobile frame 31. The lower end of the support body 373 is connected to the base 374. The balancer 371 is disposed on the upper end of the support body 373. The connector 372 is a clamping sleeve. The balancer 371 is connected to the clamping sleeve through a balancing rope 375.

[0050] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
