Description

Technical Field

[0001] This invention relates to the field of automatic metal welding technology, specifically to an automatic metal welding device. Background Technology

[0002] Steel structure beams are widely used in various fields such as construction, bridges, and industrial facilities due to their advantages such as high strength, light weight, good plasticity, and ease of processing. In the existing technology, during the welding and forming process of steel structure beams, it is generally necessary to first manually place multiple horizontal and inclined metal ribs evenly between pairs of L-shaped steel beams, and then manually weld the two ends of the horizontal and inclined ribs to the corresponding horizontal sections of the L-shaped steel beams, thereby welding a pair of L-shaped steel beams together.

[0003] However, the traditional method of welding multiple horizontal and inclined metal ribs between pairs of L-shaped steel has the following problems: 1. In the existing technology, due to the long length and large span between the pairs of L-shaped steel, the manual placement and welding of metal ribs is labor-intensive and costly. Furthermore, the efficiency, accuracy at each point, and overall consistency of the welding of the steel structure beam still need further improvement. 2. To ensure that the metal ribs do not shift during placement and welding, each rib usually needs to be individually positioned on both sides when placing them. This operation is not only cumbersome, but also requires disassembling and adjusting the original positioning of the ribs when welding steel structure beams of different sizes, which greatly increases the number of welding steps and the time spent.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention, through the cooperation of a lifting mechanism and a welding mechanism, can not only achieve precise correction, positioning, and clamping welding of multiple initially placed horizontal ribs simultaneously, but also greatly reduce the manual operation burden of positioning and welding ribs, lower labor costs, and improve the overall welding efficiency of steel structure beams. Furthermore, it can quickly adjust the positioning and welding position of the ribs, eliminating the need for repeated disassembly and positioning adjustments of the ribs, thereby greatly reducing the overall operation steps and time spent in the welding process of steel structure beams.

[0020] 2. By cooperating with the moving mechanism and the adjusting mechanism, this invention can not only enable the welding mechanism to move stably between the limited pairs of L-shaped steels, but also cooperate with the preliminary limiting structure on the opposite side of the paired L-shaped steels to further stabilize the positioning of the paired L-shaped steels during the welding process, thereby ensuring the stability and accuracy of the placement and positioning of the paired L-shaped steels and subsequent welding processing.

[0021] 3. The present invention can initially limit the opposite sides of the paired L-shaped steel beams to be welded through the adjustment mechanism. At the same time, the spacing of the limit can be adaptively adjusted according to the size and processing requirements of the L-shaped steel beams, so as to adapt to steel structure beams of different sizes and processing requirements.

[0022] 4. This invention, through the cooperation of the rotating mechanism and the welding mechanism, can realize the synchronous rotation and adjustment of all welding mechanisms to a specific angle. Thus, the clamping components in the welding mechanism can synchronously and stably rotate and adjust the multiple initially placed horizontal ribs to a specific angle for positioning and welding, further improving the efficiency of the positioning and welding of inclined ribs, while also ensuring the stability and accuracy of the overall welding of L-shaped steel.

[0032] 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.

[0033] Please see Figure 1 , Figure 2 and Figure 3 An automatic metal welding device is used to weld L-shaped steel 1 and rib plate 2. It includes a processing table 3, an adjustment mechanism 4, a moving mechanism 5, a lifting mechanism 6, a rotating mechanism 7 and a welding mechanism 8. The processing table 3 is provided with the adjustment mechanism 4 and the moving mechanism 5. The moving mechanism 5 is provided with the lifting mechanism 6. The lifting mechanism 6 is provided with the rotating mechanism 7. The rotating mechanism 7 is provided with the welding mechanism 8.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The adjustment mechanism 4 includes an L-shaped baffle 41, a rotating seat 42, a motor 43, a rotating shaft 44, a coil 45, and a cable 46. The upper side of the processing table 3 is symmetrically equipped with L-shaped baffles 41 by means of bolts. The installation position of the symmetrical L-shaped baffles 41 is adjusted left and right by means of bolts. Two sets of rotating seats 42 are symmetrically fixedly arranged on the upper side of the processing table 3, and each set consists of symmetrically distributed rotating seats 42. The left side of each rotating seat 42 is fixedly equipped with a motor 43. The symmetrical rotating seats 42 are rotatably connected to the drive end of the motor 43 by a rotating shaft 44. The left and right sides of the rotating shaft 44 are symmetrically fixedly equipped with coils 45 located between the corresponding rotating seats 42. The surface of the coil 45 is fixedly equipped with a cable 46.

[0035] When initially limiting the position of a pair of L-shaped steel beams 1, first place the pair of L-shaped steel beams 1 symmetrically on the upper side of the processing table 3, with the horizontal sections of the two L-shaped steel beams 1 facing each other. Then, use studs to position and install the pair of L-shaped baffles 41 on the opposite side of the pair of L-shaped steel beams 1, and ensure that the vertical section of the L-shaped baffle 41 is stably attached to the vertical section of the corresponding L-shaped steel beam 1, thereby initially limiting the position of the pair of L-shaped steel beams 1. The above operation method can be adaptively adjusted according to the size of the L-shaped steel beams 1 and the processing requirements to adapt to steel structure beams of different sizes and processing needs.

[0036] Please see Figure 1 , Figure 2 and Figure 3The moving mechanism 5 includes a top plate 51, a moving component 52, and an adjusting component 53; three top plates 51 that move synchronously back and forth are evenly arranged on the upper side of the processing table 3 and between the two sets of rotating seats 42, and the moving components 52 are symmetrically arranged on the three top plates 51, and the adjusting component 53 is arranged between the moving components 52.

[0037] Please see Figure 1 , Figure 2 and Figure 3 The moving component 52 includes a sliding shaft 521, an L-shaped bracket 522, a straight groove 523, a rotating roller 524, and a moving wheel 525. Two sets of sliding shafts 521 are symmetrically fixed on the lower side of the top plate 51, and each set consists of sliding shafts 521 symmetrically distributed front and back. An L-shaped bracket 522 is symmetrically slidably arranged on the lower side of the top plate 51. A straight groove 523 extending from left to right is symmetrically opened on the horizontal section of the L-shaped bracket 522. The straight groove 523 is slidably connected to the corresponding sliding shaft 521. Multiple rotating rollers 524 are evenly rotatably arranged on opposite sides of the vertical section of the symmetrical L-shaped bracket 522. Multiple moving wheels 525 are evenly rotatably arranged on the lower end of the vertical section of the L-shaped bracket 522.

[0038] When multiple drive top plates 51 are to move synchronously back and forth, the movable ends of the two front cables 46 are first connected to the front surface of the front top plate 51 through latches (the latches are existing technology and are not shown in the figure), and the movable ends of the two rear cables 46 are connected to the rear surface of the rear top plate 51 through latches (the latches are existing technology and are not shown in the figure), and the cables 46 are kept in a stable and taut state. Then, the motors 43 on the front and rear sides synchronously drive the corresponding rotating shafts 44 to rotate. The rotating shafts 44 then wind or unwind the corresponding cables 46 through the coils 45 on both sides. Thus, through the synchronous action of the cables 46 on the front and rear sides, and with the cooperation of the lifting mechanism 6, the three top plates 51 can be driven to move synchronously back and forth. The top plates 51 then drive the L-shaped brackets 522 on both sides to move synchronously back and forth. The L-shaped brackets 522 roll along the upper side of the processing table 3 through multiple moving wheels 525 at the lower end of the vertical section, which can ensure the stability of the corresponding top plate 51 during the movement.

[0039] When stabilizing the pair of L-shaped steel 1s initially positioned, the moving wheel 525 is first placed on the upper surface of the horizontal section of the corresponding L-shaped steel 1, and the rotating roller 524 is made to fit tightly against the vertical section of the corresponding L-shaped steel 1. Thus, the vertical section of the corresponding L-shaped steel 1 is pressed tightly against the vertical section of the corresponding L-shaped baffle 41 by the rotating roller 524, thereby stabilizing the pair of L-shaped steel 1s. At this time, the top plate 51 can be moved synchronously and stably between the pair of L-shaped steel 1s by winding / unwinding the corresponding cable 46. The above operation method ensures the stability and accuracy of the placement and positioning of the pair of L-shaped steel 1s and subsequent welding processing.

[0040] Please see Figure 1 , Figure 2 and Figure 3 The adjustment component 53 includes a hydraulic cylinder 531, a connecting plate 532, a linear groove 533, and a sliding shaft 534. The upper side of the central top plate 51 is symmetrically fixed with hydraulic cylinders 531 via supports. The telescopic ends of the symmetrical hydraulic cylinders 531 are fixedly connected to the horizontal section of the corresponding L-shaped bracket 522 via plates. A connecting plate 532 is fixedly installed on the opposite side of the vertical section of the symmetrical L-shaped bracket 522, located above the rotating roller 524. A linear groove 533 extending from front to back is symmetrically opened on the connecting plate 532. A sliding shaft 534, slidably connected to the linear groove 533, is fixedly installed on the side of the vertical section of the L-shaped bracket 522 on both the front and rear sides. The sliding shaft 534 has a T-shaped cross-section.

[0041] When it is necessary to stably position pairs of L-shaped steel 1 with different spacings, the installation position of the pairs of L-shaped baffles 41 is first adjusted by the studs to match the required spacing of the corresponding pairs of L-shaped steel 1. Then, the hydraulic cylinder 531 drives the corresponding L-shaped bracket 522 to move synchronously relative to or opposite to each other until the rotating roller 524 can press the vertical section of the corresponding L-shaped steel 1 and the vertical section of the corresponding L-shaped baffle 41 tightly together. At the same time, the connecting plate 532 will synchronously drive the sliding shafts 534 on the front and rear sides and the corresponding rotating roller 524 on the L-shaped bracket 522 to move synchronously to the corresponding position. The above operation method can adapt to the positioning of pairs of L-shaped steel 1 with different welding processing requirements by synchronously adjusting the position of the L-shaped bracket 522 and the rotating roller 524.

[0045] When adjusting the distance between the front and rear top plates 51 and the middle top plate 51, first slide the corresponding connecting shaft 625 back and forth along the straight groove 622. The connecting shaft 625 then drives the corresponding sliding rod 611 and the top plate 51 to move synchronously a specific distance. The docking seat 626 moves synchronously a specific distance until it is aligned with the corresponding docking hole 624. At this time, the docking seat 626 and the corresponding docking hole 624 are positioned and connected by a pin, thereby adjusting and positioning the front and rear top plates 51 at the required specific position. At the same time, during the adjustment of the top plate 51, the L-shaped brackets 522 on the front and rear sides move synchronously, and the sliding shafts 534 on the front and rear sides move synchronously along the corresponding straight groove 533 to adjust to the specific position.

[0046] When the lifting plate 612 needs to be moved up and down for adjustment, the hydraulic cylinder 627 can simultaneously drive the corresponding positioning plate 621 to move up and down to adjust a specific distance.

L-shaped end plates 825 are fixedly arranged on opposite ends of the symmetrically arranged connecting plates 824. L-shaped side plates 826 are symmetrically fixedly arranged on the end of the connecting plate 824 closest to the hydraulic cylinders 811. The horizontal sections of the L-shaped end plates 825 and L-shaped side plates 826 are both inclined downwards.

[0055] Please see Figures 1-8When positioning and welding the horizontal ribs 2 initially placed between the pairs of L-shaped steel 1, the rotating roller 524 first engages with the corresponding L-shaped baffle 41 to stably position the corresponding L-shaped steel 1. Then, the top plate 51 and L-shaped bracket 522 move synchronously between the pairs of L-shaped steel 1 through the winding and unwinding of the cable 46 until the top plate 51 moves above the corresponding horizontal ribs 2. Next, the hydraulic cylinder 627 synchronously drives all the lifting plates 612 and U-shaped rotating frame 711 to move downward. The U-shaped rotating frame 711 then drives the fixed plate 812 and the corresponding L-shaped sliding plate 822 to move downward synchronously. The L-shaped sliding plate 822 then drives the L-shaped end plate 825 and L-shaped side plate on the connecting plate 824 through the spring rod 823. 826 moves downwards synchronously until the welding torch 816 moves downwards synchronously to a specific processing position. At this time, under the action of the spring rod 823, the inclined sections of the left and right symmetrical L-shaped end plates 825 have corrected and clamped the left and right lateral positions of the corresponding horizontal rib 2 through mutual cooperation. The inclined sections of the front and rear symmetrical L-shaped side plates 826 on the connecting plate 824 have corrected and clamped the front and rear longitudinal positions of the horizontal rib 2 through mutual cooperation. At the same time, the connecting plate 824 has stably pressed and positioned the two ends of the corresponding horizontal rib 2 on the horizontal section of the corresponding L-shaped steel 1. Finally, the electric slider 815 can drive the corresponding welding torch 816 to move left and right along the guide rail 814 to perform welding processing on the contact area between the rib 2 and the L-shaped steel 1. The above operation method can simultaneously and accurately correct, limit, and press the welding of multiple initially placed horizontal ribs 2, thereby greatly reducing the manual positioning and welding workload of the ribs 2, reducing labor costs, and improving the overall welding efficiency of the steel structure beam. At the same time, by adjusting the distance between the front and rear top plates 51 and the middle top plate 51, the positioning and welding positions of the horizontal ribs 2 can be quickly adjusted, thereby avoiding repeated disassembly and adjustment of the rib 2 positioning structure, and thus greatly reducing the overall operation steps and time spent on the welding of the steel structure beam.

[0056] When the horizontally placed rib plate 2 needs to be rotated and adjusted, the corresponding U-shaped rotating frame 711 can be synchronously driven by the hydraulic cylinder 715 to rotate and adjust to a specific angle. The U-shaped rotating frame 711 drives the clamping assembly 82 to rotate, and the L-shaped sliding plate 822 then drives the L-shaped end plate 825 and L-shaped side plate 826 on the corresponding connecting plate 824 to rotate and adjust to a specific angle. The two sets of symmetrical L-shaped end plates 825 and L-shaped side plates 826 then drive the clamped and limited rib plate 2 to rotate and adjust to a specific angle. The inclined rib plate 2 can be welded by the welding gun 816 that rotates at a specific angle, thereby realizing the sequential welding of multiple evenly arranged horizontal and inclined rib plates 2 between pairs of L-shaped steel 1 (e.g., Figure 8(As shown). The above operation method can synchronously and stably rotate and adjust multiple initially placed horizontal ribs 2 to a specific angle and position them for welding, thereby further improving the efficiency of the positioning and welding of the inclined ribs 2, while also ensuring the stability and accuracy of the overall welding of the L-shaped steel 1.

[0057] When it is necessary to correct, position and weld ribs 2 of different lengths, the hydraulic cylinder 811 can drive the corresponding pairs of L-shaped sliding plates 822 to move synchronously relative to or opposite to each other by a specific distance until the spacing between the vertical sections of the left and right symmetrical L-shaped end plates 825 matches the length of the corresponding rib 2, so that the rib 2 of that length can be corrected, positioned and welded.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
