Description

Technical Field

[0001] This invention relates to the field of intelligent welding technology, and in particular to a multi-degree-of-freedom intelligent welding device for prefabricated steel structure processing. Background Technology

[0002] Prefabricated steel structures are widely used in modern buildings. The cross column, as the core load-bearing component, is composed of H-beams and T-beams orthogonally welded together and reinforced with ribs. The welding quality directly determines the structural safety of the building.

[0003] Traditional cross-shaped column welding relies on manual labor or hoisting equipment to assisted in flipping the workpiece. However, during the welding process, because cross-shaped column welding requires multi-angle operation, manual hoisting and flipping of H-beams / T-beams easily leads to positional shifts, causing weld misalignment (especially at the connection between the stiffeners and the column body), requiring repeated calibration. Simultaneously, hoisting equipment occupies a large space, making it difficult to operate flexibly in narrow workshops, severely affecting welding continuity. Furthermore, existing equipment relies on manual intervention in the assembly and positioning of H-beams and T-beams. When the T-beam is placed on the upper surface of the H-beam for assembly, there is a lack of automatic limiting mechanism; workers must manually adjust the T-beam to align its axis with the central axis of the H-beam. This process requires continuous calibration of the T-beam, but the upper surface of the H-beam lacks a physical reference, resulting in significant deviations from visual positioning. This error accumulates during the welding of multiple stiffeners, leading to excessive deviation of the final cross-shaped column axis, requiring additional correction and affecting welding efficiency. Therefore, we propose a multi-degree-of-freedom intelligent welding device for prefabricated steel structure processing. Summary of the Invention

[0021] (1) The multi-degree-of-freedom intelligent welding equipment for prefabricated steel structure processing limits the feeding process of H-beams by flipping the components to ensure accurate feeding of H-beams. During the welding process, the flipping components, together with the clamping structure in the flipping components, clamp and flip the two ends of the H-beams, which facilitates the welding components to perform multi-degree-of-freedom intelligent welding between H-beams and T-beams, as well as between the reinforcing ribs and the formed cross columns during the production process of the cross columns. There is no need for manual or external hoisting structure to assist in flipping the cross columns, which simplifies the welding process of the cross columns and improves the level of intelligence in the entire welding process.

Detailed Implementation

[0037] 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, and 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.

[0038] like Figure 1 - Figure 9 As shown, a multi-degree-of-freedom intelligent welding equipment for prefabricated steel structure processing includes a welding table 1, a support frame 2 on the outer wall of the welding table 1, an installation platform 15 fixedly installed on the upper surface of the welding table 1, an adjustable support component 14 movably installed on the upper surface of the installation platform 15, multiple connecting rods 7 fixedly installed at the upper end of the support frame 2, a fixed frame 6 fixedly connected to the lower end of the multiple connecting rods 7, multiple second electric telescopic rods 5 fixedly installed on the upper surface of the fixed frame 6, a lifting frame 4 fixedly connected to the upper end of the multiple second electric telescopic rods 5, a flipping component 8 is provided at both ends of the welding table 1 and the lifting frame 4, wherein two sets of flipping components 8 located at the same end are used in conjunction, and a welding component 9 is fixedly installed on the bottom surface of the fixed frame 6.

[0039] The welding assembly 9 includes an electric slide rail 901 fixedly connected to the bottom surface of the fixed frame 6. An electric slide table 902 is slidably installed on the bottom surface of the electric slide rail 901. A fourth electric telescopic rod 903 is fixedly installed on the bottom surface of the electric slide table 902. A fixed plate 904 is fixedly installed at the output end of the fourth electric telescopic rod 903. Intelligent automatic welding arms 907 are movably connected to both ends of the bottom surface of the fixed plate 904. A limit component 12 is fixedly installed at the center of the bottom surface of the fixed plate 904.

[0040] The upper end of the support component 14 supports an H-beam 10. A first T-beam 11 and a second T-beam 13 are respectively provided on both sides of the H-beam 10, and the first T-beam 11 and the second T-beam 13 are welded and fixed to the H-beam 10 by an intelligent automatic welding arm 907.

[0041] The flipping assembly 8 includes a fixed rail 801 fixedly connected to the outer wall of the end of the welding table 1 or the lifting frame 4. A semi-circular arc rod 804 is rotatably connected to the inner wall of the fixed rail 801. A gear ring 810 is fixedly installed on the outer wall of the end of the semi-circular arc rod 804. A clamping structure is fixedly installed on the inner wall of the semi-circular arc rod 804. The clamping structure includes a third electric telescopic rod 806 fixedly connected to the inner wall of the semi-circular arc rod 804. A rectangular groove 807 is fixedly installed at the output end of the third electric telescopic rod 806. A threaded rod 808 is rotatably installed inside the rectangular groove 807. Both ends of the threaded rod 808 are threadedly connected to clamping blocks 809. The lower end of the clamping blocks 809 slides inside the rectangular groove 807. Two symmetrically arranged drive gears 803 are rotatably installed on the outer walls of the end of both the welding table 1 and the lifting frame 4. Both drive gears 803 are meshed with the gear ring 810.

[0042] In use, the H-beams 10 forming the cross-shaped column are fed from one end of the welding table 1 to the top of the mounting platform 15. The rectangular groove 807 located at the end of the welding table 1 is pre-adjusted in height according to the model of the H-beams 10, and the spacing between the two clamping blocks 809 is adjusted. The two clamping blocks 809 can limit the movement on both sides of the H-beams. After the first T-beam 11 is welded to the H-beams 10, the H-beams 10 are raised by the supporting component 14, and the height of the lifting frame 4 is lowered by the retraction of the output end of the second electric telescopic rod 5. This completes the combination of the flipping component 8 located at the end of the lifting frame 4 and the flipping component 8 located at the end of the welding table 1. The circular structure, with the ends of the gear rings 810 in the two sets of flipping components 8 adsorbed to each other by electromagnetic locks 805 to form a whole, is then driven by the third servo motors built into both ends of the welding table 1 to rotate multiple drive gears 803. Under the meshing action of the drive gears 803 and the gear rings 810, the two gear rings 810 rotate 90 degrees. At this time, the two clamping structures rotate to correspond to the wing plates set on both sides of the H-beam 10, and clamp the ends of the wing plates on both sides of the H-beam 10 through the clamping structures. Then, the supporting component 14, welding component 9 and limiting component 12 retract and make room according to the actual situation. At this time, the two ends of the H-beam 10 are clamped. The structure is clamped and fixed, and then the gear ring 810 is rotated 180 degrees, causing the outer wall of the H-beam 10 with the first T-beam 11 mounted on it to flip downwards. Next, the height of the support component 14 is adjusted so that the upper end of the support component 14 supports the lower end of the first T-beam 11. Repeating the above steps, the second T-beam 13 is welded and fixed to the other outer wall of the H-beam 10, so that the H-beam 10, the first T-beam 11, and the second T-beam 13 combine to form a cross column. After the H-beam 10, the first T-beam 11, and the second T-beam 13 are welded together to form the cross column, the cross column is driven to rotate by the flipping component 8 clamping both ends of the cross column. The plane formed by the end edges of the first T-shaped steel 11, the second T-shaped steel 13 and the end edge of the H-shaped steel 10 is rotated to a horizontal position. At this time, the reinforcing ribs are loaded to the installation position by an external robotic arm. Then, the two ends of the reinforcing ribs are welded and fixed by the intelligent automatic welding arm 907. The cross column is driven to rotate by two sets of flipping components 8, and multiple reinforcing ribs can be welded to the periphery of the cross column. After the cross column is welded as a whole, the clamping structure at both ends separates from the cross column. At the same time, the lifting frame 4 drives one set of flipping components 8 to move upward. After the welding is completed, the steel structure cross column can be unloaded from the end of the welding table 1, completing the intelligent welding assembly of the steel structure cross column.

[0043] As a technical optimization of the present invention, the upper surface of the mounting platform 15 is provided with two symmetrically arranged sliding grooves. A bidirectional lead screw 1405 is rotatably installed inside each of the two sliding grooves. Two symmetrically arranged movable seats 1404 are threadedly connected to the outer wall of the bidirectional lead screw 1405, and the movable seats 1404 are slidably installed inside the sliding grooves. A seventh electric telescopic rod 1403 is fixedly installed on the upper end face of the movable seat 1404. The upper ends of the two seventh electric telescopic rods 1403 located on the same side are jointly fixedly installed with a mounting groove 1401. Multiple conveying rollers 1402 are rotatably installed on the upper surface of the mounting groove 1401. The multiple conveying rollers 1402 inside the mounting groove 1401 can rotate under electric drive, thus conveying the H-beam. This is prior art and will not be elaborated here. Furthermore, the height of the mounting groove 1401 can be flexibly adjusted according to the welding process of the cross column. When the H-beam enters the device, it is supported by two sets of supporting components 14, driven by a built-in second servo motor. When the double-acting lead screw 1405 rotates, the movable seats 1404 connected to the outer wall of the double-acting lead screw 1405 move simultaneously towards both ends of the double-acting lead screw 1405, or move closer to each other, under the action of the threaded transmission. The distance between the two mounting slots 1401 is adjusted according to the width of the H-beam 10. The outer walls of the two mounting slots 1401 are in contact with the inner walls of the flanges of the H-beam 10. The multiple conveying rollers 1402 inside the mounting slots 1401 are rotated by electric drive, continuously pushing the H-beam 10 towards the welding table 1. The internal conveying continues until the end of the H-beam 10 is conveyed to the flipping assembly 8 set at the other end of the welding table 1. When the outer wall of the H-beam 10 with the first T-beam 11 installed flips downward, the height of the support assembly 14 is then adjusted so that the upper end of the support assembly 14 supports the lower end of the first T-beam 11 at this time. During the flipping adjustment process when the H-beam 10 is welded with the first T-beam 11 and the second T-beam 13, the support assembly 14 can move downward to make way for the flipping space of the cross column.

[0044] As a technical optimization of the present invention, the limiting component 12 includes a fifth electric telescopic rod 1201 fixedly connected to the bottom surface of the fixed plate 904. A mounting frame 1202 is fixedly installed on the bottom surface of the fifth electric telescopic rod 1201, and a pressure roller 1203 is rotatably installed inside the mounting frame 1202. The fifth electric telescopic rod 1201 extends to press the pressure roller 1203 downward, and the pressure roller 1203 applies downward pressure to the upper end of the first T-shaped steel 11, so that the lower end of the first T-shaped steel 11 is squeezed tightly to the welding position on the upper surface of the H-shaped steel 10, thereby ensuring the welding effect of the intelligent automatic welding arm 907 at the connection between the first T-shaped steel 11 and the H-shaped steel 10.

[0045] As a technical optimization of the present invention, a sixth electric telescopic rod 1206 is fixedly installed at both ends of the mounting frame 1202. A limit block 1204 is fixedly installed at the output end of the sixth electric telescopic rod 1206, and a limit groove 1205 is opened at the lower end of the limit block 1204. The length of the sixth electric telescopic rod 1206 can be adjusted according to the thickness of the upper end of the first T-shaped steel 11. After the sixth electric telescopic rod 1206 is adjusted, the upper end of the first T-shaped steel 11 can be limited by the gap between the pressure roller 1203 and the limit block 1204. The limit groove 1205 opened at the lower end of the limit block 1204 can be used to snap and fix the reinforcing rib during the subsequent welding process, thereby ensuring the welding effect of the reinforcing rib.

[0046] As a technical optimization of the present invention, a first servo motor 905 is fixedly installed on the upper surfaces of both ends of the fixed plate 904, and a rotating seat 906 is fixedly installed on the output end of the first servo motor 905. The bottom surface of the rotating seat 906 is rotatably connected to the end of the intelligent automatic welding arm 907. By driving the rotating seat 906 to rotate through the first servo motor 905, the degree of freedom of the intelligent automatic welding arm 907 during welding can be improved, making it easier for the intelligent automatic welding arm 907 to adjust its angle according to different welding positions when welding the cross column.

[0047] As a technical optimization of the present invention, auxiliary components 3 are provided on both outer walls of the welding table 1. Each auxiliary component 3 includes multiple first electric telescopic rods 301 fixedly connected to the outer wall of the welding table 1. A long plate 302 is fixedly installed at the upper ends of the multiple first electric telescopic rods 301. Multiple eighth electric telescopic rods 303 are fixedly installed on the outer wall of the long plate 302. A positioning block 304 is fixedly installed at the end of each eighth electric telescopic rod 303. The positioning block 304 has an L-shaped cross-section. Proximity sensors are fixedly installed at the ends of the multiple eighth electric telescopic rods 303. These sensors connect to the H-beam 1 via the outer walls of the multiple positioning blocks 304. The ends of the first T-shaped steel 11 and the first T-shaped steel 11 abut against each other, which can pre-fix the installation position of the first T-shaped steel 11. Since the ends of multiple eighth electric telescopic rods 303 are equipped with proximity sensors, when the metal intelligent automatic welding arm 907 approaches the eighth electric telescopic rod 303, the proximity sensor transmits an electrical signal to the controller. Under the action of the controller, the eighth electric telescopic rod 303 retracts, making room for the intelligent automatic welding arm 907 during welding. Multiple positioning blocks 304 make way in sequence under the action of the proximity sensor, ensuring the welding effect of the first T-shaped steel 11 and the H-shaped steel 10.

[0048] As a technical optimization of the present invention, a reinforcing rod 305 is also fixedly installed on the outer wall of the output end of the first electric telescopic rod 301. The end of the reinforcing rod 305 is fixedly connected to the bottom surface of the long plate 302, and the reinforcing rod 305 is inclined. The inclined reinforcing rod 305 can form a stable triangular structure between the end of the first electric telescopic rod 301 and the long plate 302, thus ensuring the structural strength of the long plate 302.

[0049] As a technical optimization of the present invention, electromagnetic locks 805 are fixedly installed at both ends of the gear ring 810, and the electromagnetic locks 805 at one end of the two sets of gear rings 810 are used in cooperation; by the mutual attraction and combination of the two electromagnetic locks 805, the two gear rings 810 can be combined into a complete ring structure, and the setting of electromagnetic locks 805 can enhance the connection strength of the connection end of the two gear rings 810.

[0050] As a technical optimization of the present invention, a protruding rib is fixedly installed on the outer wall of the semi-circular arc rod 804, and a groove is opened on the inner wall of the fixed rail 801, with the protruding rib slidably installed inside the groove. Multiple balls 802 are rotatably installed on the inner wall of the fixed rail 801. When the two sets of flipping components 8 are combined into a circular structure, the semi-circular arc rod 804 can slide after being combined with any fixed rail 801. The multiple balls 802 located between the semi-circular arc rod 804 and the fixed rail 801 can reduce the friction between the two, making the semi-circular arc rod 804 slide more smoothly.

[0051] Working principle of the invention:

[0052] In use, the H-beams 10 forming the cross-shaped column are fed from one end of the welding table 1 onto the mounting platform 15. The rectangular groove 807 at the end of the welding table 1 is pre-adjusted in height according to the model of the H-beams 10, and the spacing between the two clamping blocks 809 is also adjusted. The two clamping blocks 809 can limit the movement of the H-beams 10 on both sides. When the H-beams 10 enters the device, they are supported by two sets of supporting components 14. A built-in second servo motor drives the bidirectional lead screw 1405 to rotate, thus causing the screw to rotate under the action of threaded transmission. The movable seats 1404 connected to the outer wall of the bidirectional lead screw 1405 move simultaneously to both ends of the bidirectional lead screw 1405 or move closer to each other. The distance between the two mounting slots 1401 is adjusted according to the distance between the two wing plates of the H-beam 10. The outer walls of the two mounting slots 1401 are in contact with the inner walls of the wing plates of the H-beam. The multiple conveying rollers 1402 inside the mounting slots 1401 are rotated by electric drive to continuously convey the H-beam 10 into the welding table 1 until the end of the H-beam 10 is conveyed into the flipping assembly 8 set at the other end of the welding table 1.

[0053] Next, the first T-shaped steel 11 is transported above the H-shaped steel 10. When the first T-shaped steel 11 moves along the upper surface of the H-shaped steel 10, its upper end is limited by the limiting component 12. Multiple positioning blocks 304 are provided on both sides of the upper surface of the H-shaped steel 10. The positioning blocks 304 located on both sides of the H-shaped steel 10 are symmetrically arranged and can limit the two sides of the first T-shaped steel 11, so that the lower end of the first T-shaped steel 11 to be connected to the H-shaped steel 10 is on the central axis of the upper surface of the H-shaped steel 10.

[0054] Based on the height of the upper end of the first T-shaped steel 11, the extension length of the output end of the fifth electric telescopic rod 1201 is adjusted. Then, the distance between the lower end of the limiting block 1204 and the outer wall of the pressure roller 1203 is matched with the upper end thickness of the first T-shaped steel 11 by adjusting the sixth electric telescopic rod 1206. During the process of conveying the first T-shaped steel 11 to the upper surface of the H-shaped steel 10, the outer walls of the multiple positioning blocks 304 located on both sides of the first T-shaped steel 11 contact the upper end outer wall of the first T-shaped steel 11 in sequence. When the first T-shaped steel 11 is completely conveyed to the upper end surface of the H-shaped steel 10, the position of the first T-shaped steel 11 can be pre-fixed by the positioning blocks 304. Then, the connection between the first T-shaped steel 11 and the H-shaped steel 10 is welded by the welding assembly 9.

[0055] During the welding process, the first servo motor 905 drives the rotating seat 906 to rotate, and in conjunction with the adjustment of the intelligent automatic welding arms 907, two sets of intelligent automatic welding arms 907 can simultaneously weld both sides of the connection between the first T-shaped steel 11 and the H-shaped steel 10. The intelligent automatic welding arms 907 are existing technology and will not be described in detail here; the Yaskawa MC2000Ⅱ is commonly used. The electric slide table 902 slides on the electric slide rail 901, driving the fixed plate 904 to move, thereby allowing the two sets of intelligent automatic welding arms 907 to weld the connection between the first T-shaped steel 11 and the H-shaped steel 10 along their length. Since multiple eighth electric telescopic rods 303 are equipped with proximity sensors at their ends, when a metal intelligent automatic welding arm 907 approaches the eighth electric telescopic rod 303, the proximity sensor transmits an electrical signal to the controller (CPM1A). At the PLC controller, the eighth electric telescopic rod 303 retracts under the control of the controller, making room for the intelligent automatic welding arm 907 during welding. Multiple positioning blocks 304 move out of position sequentially under the action of proximity sensors, ensuring the welding effect of the first T-shaped steel 11 and the H-shaped steel 10. When the intelligent automatic welding arm 907 welds the connection between the first T-shaped steel 11 and the H-shaped steel 10, the fifth electric telescopic rod 1201 extends and presses the pressure roller 1203 downward. The pressure roller 1203 applies downward pressure to the upper end of the first T-shaped steel 11, so that the lower end of the first T-shaped steel 11 is squeezed tightly with the upper surface of the H-shaped steel 10 at the welding position, ensuring the welding effect of the intelligent automatic welding arm 907 at the connection between the first T-shaped steel 11 and the H-shaped steel 10. In this technical solution, the electric telescopic rod and servo motor are all controlled by the controller.

[0056] After the first T-beam 11 and H-beam 10 are welded together, the H-beam 10 is raised by the supporting component 14, and the height of the lifting frame 4 is lowered by the retraction of the output end of the second electric telescopic rod 5. This allows the flipping component 8 at the end of the lifting frame 4 to combine with the flipping component 8 at the end of the welding table 1 to form a complete circular structure. The gear rings 810 in the two sets of flipping components 8 are attracted to each other by the electromagnetic lock 805 to form a whole. Then, the third servo motors built into both ends of the welding table 1 drive multiple drive gears 803 to rotate. Under the meshing action of the drive gears 803 and the gear rings 810, the two gear rings 810 rotate 90 degrees. At this time, the two clamping structures rotate to the sides of the H-beam 10. The wing plates are set accordingly. The ends of the wing plates on both sides of the H-beam 10 are clamped by the clamping structure. Then, the supporting component 14, welding component 9 and limiting component 12 retract and make room according to the actual situation. At this time, the two ends of the H-beam 10 are clamped and fixed by the clamping structure. Then, the gear ring 810 is rotated 180 degrees, so that the outer wall of the H-beam 10 on which the first T-beam 11 is installed can be flipped downward. Then, the height of the supporting component 14 is adjusted so that the upper end of the supporting component 14 supports the lower end of the first T-beam 11. Repeat the above steps to weld and fix the second T-beam 13 to the other outer wall of the H-beam 10, so that the H-beam 10, the first T-beam 11 and the second T-beam 13 are combined to form a cross column.

[0057] After the H-beam 10, the first T-beam 11, and the second T-beam 13 are welded together to form a cross column, the cross column is rotated by the flipping assembly 8, which clamps both ends of the cross column. This causes the plane formed by the end edges of the first T-beam 11, the second T-beam 13, and the end edge of the H-beam 10 to rotate to a horizontal position. At this time, the reinforcing rib is loaded to the installation position by an external robotic arm. The output end of the fifth electric telescopic rod 1201 extends and is secured to the reinforcing rib by the limiting groove 1205 at the lower end of the limiting block 1204. The fifth electric telescopic rod 1201 continuously applies downward pressure to the reinforcing rib. The force is used to weld and fix the two ends of the reinforcing ribs to the corresponding positions on the H-beam 10, the first T-beam 11, and the second T-beam 13 through two sets of intelligent automatic welding arms 907. During this process, the cross column is rotated by two sets of flipping components 8, and multiple reinforcing ribs can be welded to the periphery of the cross column. After the cross column is welded as a whole, the clamping structure at both ends separates from the cross column. At the same time, the lifting frame 4 drives one of the flipping components 8 to move upward. After the welding is completed, the steel structure cross column can be unloaded from the end of the welding table 1, completing the intelligent welding assembly of the steel structure cross column.
