Description

[0001] This application is a divisional application of the application filed on October 10, 2025, with application number 2025114430747 and invention title "An integrated laser cutting and welding device for steel structure processing". Technical Field

[0002] This invention belongs to the field of steel structure welding technology, and specifically relates to an integrated laser cutting and welding equipment for steel structure processing. Background Technology

[0003] Steel structures are structures made of steel materials and are one of the main types of building structures. When using steel structures, welding is often required according to usage needs. Before welding, it is also necessary to confirm whether the welding end faces are flat so that the end faces fit together.

[0004] A search revealed that Chinese Patent Publication No. CN117206683A, published on December 12, 2023, discloses a welding device for irregularly shaped tubes used in fitness equipment. This device belongs to the field of fitness equipment processing technology and includes a base, a first driving component, a clamping component, a welding component, and a second driving component. Two sets of clamping components are rotatably mounted on the upper part of the base to clamp two sets of square tubes respectively. The first driving component is fixedly mounted on the upper part of the base to drive the two sets of clamping components to rotate synchronously, thereby driving the two sets of square tubes to rotate synchronously. The welding component is positioned between the two sets of clamping components. Compared to existing technologies, this invention achieves automatic welding of the two sets of square tubes by rotating them relative to the welding component. Furthermore, during the rotation of the two sets of square tubes, the distance between the welding component and the welding seam of the square tubes can be adaptively adjusted, thereby improving the welding effect and welding quality between the two sets of square tubes.

When the first guide plate is a fan-shaped ring with a central angle greater than 180°, the two work together to complete the circular motion of the welding laser generator to perform the welding of the annular weld.

The two sets of first guide assemblies can be adjusted in position by the first rotating ring and the second rotating ring, respectively, and can be adjusted in angle by the two sets of electric turntables to fix the other end of the irregular column steel.

[0019] 4.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides an integrated laser cutting and welding equipment for steel structure processing, including a processing platform 1. For example, as shown... Figure 1 and Figure 2As shown, a first electric slide 2 is provided at one edge of the top of the processing platform 1; a first electric push rod 3 is driven to the output end of the first electric slide 2; a connecting seat 4 is driven to the output end of the first electric push rod 3; a second electric slide 5 is provided on one side wall of the connecting seat 4; a second electric push rod 6 is driven to the output end of the second electric slide 5; a welding mechanism 7 is driven to the output end of the second electric push rod 6; the first electric slide 2, the first electric push rod 3, the connecting seat 4, the second electric slide 5, and the second electric push rod 6 together constitute a driving mechanism; a limiting cutting mechanism 8 is movably passed through the top of the processing platform 1; an adjustment cavity 9 is provided inside the processing platform 1; two sets of first support columns 10 are symmetrically movably passed through the top of the adjustment cavity 9. The bottom of the first support column 10 is set as an inclined surface; two sets of lead screws 11 are provided in the adjustment cavity 9; one end of the two sets of lead screws 11 is fixedly connected, and the other end is rotatably connected to the inner walls on both sides of the adjustment cavity 9; the thread directions of the two sets of lead screws 11 are opposite, and their central axes are on the same straight line; two sets of sliders 12 are slidably connected to the bottom inner wall of the adjustment cavity 9; the two sets of sliders 12 are threadedly connected to a set of lead screws 11 respectively; two sets of limiting blocks 13 are symmetrically connected to the top of the two sets of sliders 12; each set of limiting blocks 13 is movably inserted through the limiting cutting mechanism 8; two sets of abutments 14 are symmetrically connected to the top of the two sets of sliders 12; the top of each set of abutments 14 is set as an inclined surface, and movably abuts against the bottom of the corresponding set of first support columns 10.

[0025] When performing laser welding of column steel, the two sets of column steel are first fixed to the top of the limiting cutting mechanism 8 and connected. Then, the drive mechanism is controlled to drive the welding mechanism to perform the welding work on the column steel. When it is necessary to disassemble the limiting component, by controlling the rotation of the two sets of lead screws 11, under the threaded connection between the two sets of lead screws 11 and the two sets of sliders 12, the two sets of limiting blocks 13 move to opposite sides and disengage from the limiting cutting mechanism 8. Then, the top inclined surfaces of the two sets of abutments 14 respectively abut against the bottom inclined surfaces of the corresponding set of first support columns 10, so that the two sets of first support columns 10 abut against the bottom of the limiting cutting mechanism 8 and lift the limiting cutting mechanism 8 to complete the disassembly work. The process is simple and quick, improving the maintenance efficiency of the cutting and welding mechanism.

[0026] For example, such as Figure 3 and Figure 4As shown, the welding mechanism 7 includes a mounting base 701; a movable groove 702 is provided at the bottom of the mounting base 701; a first guide plate 703 movably passes through the movable groove 702; the cross-section of the first guide plate 703 is annular, and the central angle is greater than 180°; an electric guide rail 704 is provided on the inner wall of the first guide plate 703; a welding laser generator 705 is drivenly connected to the output end of the electric guide rail 704; a first guide groove 706 is provided on the outer wall of the first guide plate 703; the... The inner wall of the first guide groove 706 is provided with several sets of first guide teeth 707 at equal intervals; the bottom of the mounting base 701 is provided with two sets of sealing plates 708 symmetrically; the cross-section of each set of sealing plates 708 is L-shaped; the mounting base 701 is provided with a transmission cavity 710; a guide motor 709 is provided on one side wall of the mounting base 701; the output end of the guide motor 709 extends into the transmission cavity 710 and is connected to a guide gear 711; the guide gear 711 is meshed with several sets of first guide teeth 707.

[0027] During laser welding of column steel sections, two sets of column steel sections are fixed to the top of the limiting cutting mechanism 8. Then, the welding laser generator 705 outputs a laser to weld the annular weld seam of the two sets of column steel sections. Simultaneously, the limiting cutting mechanism 8 drives the two sets of column steel sections to rotate synchronously until the welding is completed. When the two sets of column steel sections have an irregular shape and cannot rotate synchronously, the guide motor 709 can be controlled to drive the guide gear 711 to rotate. Under the meshing connection between the guide gear 711 and several sets of first guide teeth 707, the first guide plate 703 moves in an arc. Furthermore, the electrical circuit inside the first guide plate 703... The moving guide rail 704 can drive the welding laser generator 705 to move in an arc. When the first guide plate 703 is a fan-shaped ring with a central angle greater than 180°, the two work together to complete the circumferential motion of the welding laser generator 705 to perform the welding work of the annular weld. This avoids the need for manual welding when the steel structure workpiece cannot rotate. After the welding laser generator 705 moves into the movable groove 702, it can control two sets of L-shaped sealing plates 708 to close the movable groove 702, preventing the welding laser generator 705 from being damaged by external forces. This improves the use effect of the welding device while also improving the protection effect.

[0028] For example, such as Figure 5As shown, the limiting cutting mechanism 8 includes a limiting base 801; two sets of limiting grooves 802 are symmetrically opened on the bottom two side walls of the limiting base 801; each set of limiting blocks 13 is movably inserted into the corresponding set of limiting grooves 802; the top of the limiting base 801 is provided with a first rotating ring 803 and a second rotating ring 804; the top of the first rotating ring 803 and the second rotating ring 804 is provided with a set of electric turntables 805; the top of each set of electric turntables 805 is drivenly connected to a set of second... Support column 806; each set of second support columns 806 has a set of first guide components 807 at its top; the top of the limiting base 801 has a collection groove 808; the collection groove 808 is a circular groove; two sets of auxiliary support plates 809 are slidably connected to the inner wall of the collection groove 808; each set of auxiliary support plates 809 has a set of second guide components 810 at its top; each set of second guide components 810 has a set of end face cutting components 811 at the end away from the second rotating ring 804.

[0029] For example, such as Figure 6 As shown, the second guide assembly 810 includes a first mounting plate 8101; the first mounting plate 8101 has a U-shaped cross-section; two sets of support rollers 8102 are symmetrically arranged on the bottom inner wall of the first mounting plate 8101; two sets of third electric push rods 8103 are symmetrically arranged on the top two outer walls of the first mounting plate 8101; the output end of each set of third electric push rods 8103 extends into the first mounting plate 8101 and is connected to a set of steering rollers 8104.

[0030] During laser welding of column steel, under normal circumstances, the central axes of the two sets of first guide components 807 and second guide components 810 are on the same straight line. The two sets of column steel are placed in the corresponding sets of first guide components 807 and second guide components 810, respectively. The corresponding support rollers 8102 support the column steel. Then, the steering rollers 8104 are controlled to abut against the outer wall of the column steel to rotate the column steel and complete the welding of the annular weld. When the two sets of column steel are irregularly shaped, one end of the two sets of column steel is fixed to the two sets of second guide components 810. The positions of the two sets of first guide components 807 can be adjusted by the first rotating ring 803 and the second rotating ring 804, respectively, and the angle can be adjusted by the two sets of electric turntables 805 to fix the other end of the irregular column steel. This allows the cutting and welding device to fix irregularly shaped column steel of different shapes, improving the steel structure limiting effect of the cutting and welding device.

[0031] For example, such as Figure 7 and Figure 8As shown, the end face cutting assembly 811 includes several sets of fourth electric push rods 8111; the several sets of fourth electric push rods 8111 are mounted on the side wall of the first mounting plate 8101 away from the second rotating ring 804; a guide ring 8112 is connected to the output end of the several sets of fourth electric push rods 8111; a through groove is opened at the top of the guide ring 8112, and the length of the through groove is smaller than the diameter of the guide ring 8112; a second guide groove 8113 is opened on the inner wall of the guide ring 8112; the second guide groove 8113 contains... A second guide plate 8114 is slidably connected; the cross-section of the second guide plate 8114 is fan-shaped; a second mounting plate 8115 is provided on the side wall of the second guide plate 8114 away from the first mounting plate 8101; a cutting laser generator 8116 and an optical attenuator 8117 are symmetrically arranged on the inner wall of the second mounting plate 8115; a number of laser rangefinders 8118 are equally spaced on the inner wall of the second mounting plate 8115; a number of second guide teeth 8119 are equally spaced on the outer wall of the second guide plate 8114.

[0032] During laser welding of column steel, before the two sets of column steel are joined, several sets of fourth electric push rods 8111 are controlled to move the guide ring 8112 toward the welding end face of the column steel. Multiple sets of laser rangefinders 8118 are installed on the inner wall of the second mounting plate 8115 to detect the welding end face of the column steel. If the end face of the column steel is not flat, the first abnormal signal is used as a reference to control the cutting laser generator 8116 to reach the corresponding position and start. At the same time, the second guide plate 8114 is controlled to drive the second mounting plate 8115 to rotate, so that the cutting laser generator 8116 can perform flat cutting on the welding end face of the column steel and perform a corresponding degree of preheating. This not only avoids welding abnormalities caused by uneven end faces, but also improves the quality of the welding work.

[0033] By controlling the first guide plate 703 to move in an arc, and controlling the electric guide rail 704 inside the first guide plate 703 to drive the welding laser generator 705 to move in an arc, and when the first guide plate 703 is a fan-shaped ring with a central angle greater than 180°, the two work together to complete the circular motion of the welding laser generator 705 to perform the welding work of the annular weld, avoiding the need for manual welding when the steel structure workpiece cannot rotate. After the welding laser generator 705 moves into the movable groove 702, it can control the two sets of L-shaped sealing plates 708 to seal the movable groove 702, preventing the welding laser generator 705 from being damaged by external forces, thus improving the use effect of the welding device and the protection effect.

[0034] By controlling several sets of fourth electric push rods 8111 to drive the guide ring 8112 to move toward the welding end face of the column steel, and by setting multiple sets of laser rangefinders 8118 on the inner wall of the second mounting plate 8115 to detect the welding end face of the column steel, the cutting laser generator 8116 is then controlled to reach the corresponding position and start, while the second guide plate 8114 is controlled to drive the second mounting plate 8115 to rotate, so that the cutting laser generator 8116 can perform flat cutting on the welding end face of the column steel, and at the same time perform a corresponding degree of preheating. This not only avoids welding abnormalities caused by uneven end faces, but also improves the quality of the welding work.

[0035] Two sets of column steel are placed in corresponding sets of first guide components 807 and second guide components 810, respectively. The corresponding support rollers 8102 support the column steel. Then, the steering rollers 8104 are controlled to abut against the outer wall of the column steel to rotate the column steel and complete the welding of the annular weld. When the two sets of column steel are irregularly shaped, one end of the two sets of column steel is fixed to the two sets of second guide components 810. The two sets of first guide components 807 can be adjusted in position by the first rotating ring 803 and the second rotating ring 804, respectively, and can be adjusted in angle by the two sets of electric turntables 805 to fix the other end of the irregular column steel. This allows the cutting and welding device to fix irregularly shaped column steel of different shapes, improving the steel structure limiting effect of the cutting and welding device.

[0036] By controlling the rotation of the two sets of lead screws 11, and through the threaded connection between the two sets of lead screws 11 and the two sets of sliders 12, the two sets of limiting blocks 13 move toward opposite sides and disengage from the limiting cutting mechanism 8. Subsequently, the top inclined surfaces of the two sets of abutments 14 respectively abut against the bottom inclined surfaces of the corresponding set of first support columns 10, so that the two sets of first support columns 10 abut against the bottom of the limiting cutting mechanism 8 and lift the limiting cutting mechanism 8 to complete the disassembly work. The process is simple and quick, improving the maintenance efficiency of the cutting and welding mechanism.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
