Description

Technical Field

[0001] This invention relates to the field of steel plate processing and welding technology, and in particular to an automatic welding device for steel plate processing. Background Technology

[0002] In modern industrial production, steel plate welding is an indispensable key process in many manufacturing fields, widely used in construction, machinery manufacturing, shipbuilding, bridge engineering, and other industries. With the continuous expansion of industrial production scale and the increasing demands for product quality, traditional manual steel plate welding methods have gradually become insufficient to meet actual production needs, leading to the emergence and widespread application of automatic welding equipment. However, existing automatic welding equipment for steel plate processing still faces several problems in practical applications, as follows: In existing automated welding equipment, steel plate placement, welding surface cleaning, and the motion control of each component are typically independent operations, lacking an effective coordination mechanism. In actual production, operators need to control different components separately; for example, manually placing the steel plate first, then starting a separate cleaning device to treat the welding surface, and finally adjusting the welding device to perform the welding. This approach not only increases operational complexity and time costs but also makes precise synchronization between components difficult, resulting in low production efficiency. Especially in large-scale continuous production, this inefficient operating mode severely impacts the overall production schedule and fails to meet the demands of modern industrial production for high efficiency.

[0003] The cleanliness of the welded surface of steel plates is one of the key factors affecting weld quality. Existing automatic welding equipment has significant shortcomings in weld surface cleaning. On the one hand, the cleaning range and force of the equipment are limited, making it difficult to perform comprehensive and meticulous cleaning and polishing of complex areas such as the sides of the steel plate, resulting in residual oil, rust, scale, and other impurities on the welded surface. On the other hand, the position adjustment of the cleaning equipment is not flexible enough, and it cannot automatically adjust the cleaning area according to the actual size of the steel plate and the welding position, leaving some welded surfaces uncleaned. These problems seriously affect the quality of the weld, leading to defects such as porosity, cracks, and slag inclusions, reducing the strength and reliability of the welded joint, and thus affecting the safety and stability of the entire steel plate structure.

[0004] The cleaning process of steel plate welding surfaces generates a large amount of metal powder and other impurities. Most existing automated welding equipment lacks an effective powder collection system, causing this powder to fly everywhere during the cleaning process, severely polluting the working environment. This flying powder not only harms the health of operators, such as causing respiratory diseases through inhalation, but also damages surrounding equipment and facilities, affecting their normal operation and lifespan. Furthermore, if the cleaning powder is not collected and treated in a timely and effective manner, it will lead to resource waste and environmental pollution, failing to meet the requirements of modern industrial production for environmental protection and sustainable development.

[0021] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0022] Example

[0023] like Figures 1-6As shown in the figure, an automatic welding device for steel plate processing according to one embodiment of the present invention includes a worktable 1, which is used to install and place welding-related components. A placement plate 2, which can move synchronously relative to each other, is symmetrically arranged on the top of the worktable 1. The placement plate 2 is used to place the steel plate to be welded. A grinding component 3 is arranged on the side of the placement plate 2, which is used to clean and polish the welding surface of the steel plate. Specifically, the grinding assembly 3 includes a grinding head 32 positioned above the side of the placement plate 2, used for cleaning and polishing the side of the steel plate; a suspension frame 31 is provided on the side of the placement plate 2, used to move the grinding head 32; the grinding head 32 is mounted on the side of the suspension frame 31 via bearings, a second chain disc 34 is mounted at the end of the grinding head 32, and a first chain disc 33 is mounted on the side of the suspension frame 31; the first chain disc 33 and the second chain disc 34 are connected by a chain 35, when the first chain disc 33 rotates, it drives the second chain disc 34 to rotate via the chain 35, thereby driving the grinding head 32 to rotate. A rotatable gear disc 36 is mounted at the end of the first chain disc 33, used to drive the grinding head 32 to rotate when rotating. A transmission unit 4 is installed on the top of the workbench 1. The transmission unit 4 is used to drive the grinding assembly 3 to rotate and shift when the placement plate 2 moves, and to adjust the cleaning position of the grinding assembly 3. A drive unit 5 is installed on the back of the workbench 1. The drive unit 5 is used to drive the placement plate 2 to move relative to the workbench 1. With this device, steel plate placement, automatic cleaning and polishing of the welding surface, and coordinated movement of various components can be realized, providing good conditions for steel plate welding.

[0024] In this invention, the transmission unit 4 includes a support frame 41 mounted on the side of the placement plate 2. A suspension rod 42 is mounted on the top of the support frame 41, and a movable rack 43 is provided at the suspension rod 42. The rack 43 is used to drive the suspension frame 31 to move during movement. An L-shaped slide rod 431 is mounted on the top of the rack 43. The L-shaped slide rod 431 is inserted into the suspension rod 42 to suspend the rack 43, allowing it to move stably on the suspension rod 42. By moving the rack 43, the suspension frame 31 can be moved, thereby driving the grinding assembly 3 to perform cleaning work in a suitable position.

[0025] In this invention, a gear assembly 44 is mounted on the side of the support frame 41. The gear assembly 44 drives the rack 43 to move when it rotates. A second rack 45 is provided on one side of the gear assembly 44. The second rack 45 drives the gear assembly 44 to rotate when the placement plate 2 moves. When the placement plate 2 moves, the second rack 45 interacts with the gear assembly 44, that is, the second rack 45 meshes with the gear disk 443 in the gear assembly 44, causing the gear assembly 44 to rotate, thereby driving the rack 43 to move. Through the movement of the placement plate 2, and the transmission of the rack 45 and the gear assembly 44, the movement of the rack 43 is realized, providing power for the movement of the grinding assembly 3.

[0026] In this invention, the gear assembly 44 includes a mounting plate 441 installed on one side of the support frame 41. A rotating rod 442 is rotatably connected to the top of the mounting plate 441 via a bearing. A first gear disc 443 and a second gear disc 444 are mounted on the surface of the rotating rod 442, with the second gear disc 444 positioned above the first gear disc 443. The first gear disc 443 meshes with a second rack 45. When the placement plate 2 moves, the second rack 45 moves, driving the first gear disc 443 to rotate through meshing. Since both the first gear disc 443 and the second gear disc 444 are mounted on the rotating rod 442, the rotation of the first gear disc 443 drives the second gear disc 444 to rotate. The second gear disc 444 meshes with the first rack 43, and its rotation drives the first rack 43 to move, thereby driving the grinding assembly 3 to move. Through the structure and transmission relationship of this gear assembly 44, the linkage between the movement of the placement plate 2 and the movement of the grinding assembly 3 is achieved.

[0027] In this invention, a support rod 46 is installed on the top of the workbench 1. The support rod 46 is used to elevate the rack 45, positioning it in a suitable position for engagement with the gear assembly 44. A support rod 48 is installed on the top of the workbench 1, and a rack 47 is installed on the side of the support rod 48. The rack 47 meshes with the gear disc 36. When the suspension frame 31 moves, it drives the gear disc 36 to move. Because the gear disc 36 meshes with the rack 47, it rotates during movement, thereby driving the grinding head 32 to rotate. Through the arrangement of the support rods 46 and 48, and the meshing of the rack 47 and the gear disc 36, the linkage between the movement of the suspension frame 31 and the rotation of the grinding head 32 is achieved.

[0028] In this invention, the drive unit 5 includes a dual-axis synchronous motor 51 mounted on the top of the worktable 1. A synchronously rotatable threaded rod 52 is mounted at the output of the dual-axis synchronous motor 51. Threaded cylinders 53 of the same size are mounted on the surface of each threaded rod 52. A sliding seat 54 is mounted on the side of each threaded cylinder 53 and is connected to the placement plate 2. When the dual-axis synchronous motor 51 starts, it drives the threaded rod 52 to rotate synchronously, causing the threaded cylinders 53 to move on the threaded rod 52. This movement, via the sliding seat 54, moves the placement plate 2, achieving relative motion of the placement plate 2. Through the structure of the drive unit 5, the movement of the placement plate 2 can be precisely controlled, meeting the requirements of steel plate processing.

[0029] In this invention, a material extraction section 6 is installed on the surface of the workbench 1 to collect the powder generated during the cleaning process of the grinding assembly 3. A storage box 7 with a door is installed at the bottom of the workbench 1 to store the cleaned powder. A base plate 8 is installed at the bottom of the storage box 7, which supports the entire device and ensures its stability. Through the arrangement of the material extraction section 6 and the storage box 7, the powder generated during the steel plate cleaning process can be effectively collected and processed, maintaining a clean working environment.

[0030] In this invention, the material extraction unit 6 includes an extraction cylinder 61 installed on one side of the workbench 1. A piston rod 62 is inserted into the extraction cylinder 61, and an extraction pipe 63 is installed on the surface of the extraction cylinder 61. A feed groove 21 is provided at the top side of the placement plate 2. The extraction pipe 63 is inserted into the feed groove 21 to collect the powder in the feed groove 21. A discharge pipe 64 is installed on one side of the extraction unit 6, which extends into the bottom plate 8 to transport the collected powder to the storage box 7. When the piston rod 62 moves within the extraction cylinder 61, it creates a negative pressure inside the extraction cylinder 61, drawing the powder from the feed groove 21 into the extraction cylinder 61 through the extraction pipe 63, and then discharging it into the storage box 7 through the discharge pipe 64. Through the structure and working principle of this extraction unit 6, the effective collection and transportation of cleaning powder from steel plates is achieved.

[0031] In this invention, the extraction pipe 63 includes a connecting pipe 631 mounted on the surface of the extraction section 6. A corrugated pipe 632 is installed at the end of the connecting pipe 631. The corrugated pipe 632 has a certain degree of flexibility to adapt to different positions of the feed trough 21. A second connecting pipe 633 is installed at the end of the corrugated pipe 632 and is inserted into the feed trough 21. One-way valves are installed at both the connecting pipe 631 and the discharge pipe 64. The one-way valves ensure that the extracted powder can only flow in one direction, preventing powder from flowing back into the feed trough 21 or the extraction cylinder 61. Through the structure of the extraction pipe 63 and the one-way valves, the efficiency and reliability of powder collection are improved, and secondary pollution caused by powder backflow is avoided.

[0032] In this invention, a connecting plate 23 is mounted on the surface of the placement plate 2, and a limiting piece 65 is mounted on the end of the piston rod 62, connecting the limiting piece 65 to the connecting plate 23. When the placement plate 2 moves, the connecting plate 23 drives the limiting piece 65 to move, which in turn drives the piston rod 62 to perform piston movement at the extraction cylinder 61, thereby realizing the extraction and conveying of powder. A triangular plate 22 is installed in the feed trough 21 of the placement plate 2. The triangular plate 22 can prevent the dust from being pushed into the feed trough 21 by the movement of the placement plate 2 and then scattered again, thus playing a blocking role. Through the connection of the connecting plate 23 and the limiting piece 65, the movement of the placement plate 2 and the movement of the piston rod 62 are linked; the setting of the triangular plate 22 further improves the powder collection effect.

[0033] The workflow of this invention is as follows: The steel plate to be welded is placed on a symmetrical, synchronously movable placement plate 2 on the top of the workbench 1. A dual-axis synchronous motor 51, installed in the drive unit 5 on the back of the workbench 1, is activated. The output of the dual-axis synchronous motor 51 drives a synchronously rotatable threaded rod 52 to rotate. The threaded cylinder 53 on the surface of the threaded rod 52 moves along the threaded rod 52, driving the placement plate 2 to move relative to it via a sliding seat 54. As the placement plate 2 moves, a rack 45 mounted on its side moves accordingly. The rack 45 meshes with a gear 443 in a gear assembly 44 mounted on the side of the support frame 41. The movement of the rack 45 drives the gear 443 to rotate through the meshing action. Since both the gear 443 and the gear 444 are mounted on a rotating rod 442 rotatably connected to the top of the mounting plate 441 via bearings, the rotation of the gear 443 drives the rotation of the gear 444. Gear 2 444 meshes with rack 1 43, which is movable and mounted on suspension rod 42. Rotation of gear 2 444 drives rack 1 43 to move. An L-shaped slide bar 431 mounted on the top of rack 1 43 inserts into suspension rod 42, allowing rack 1 43 to move stably on suspension rod 42. The movement of rack 1 43 drives the grinding assembly 3, mounted on its side via suspension bracket 31, to move, adjusting the cleaning position of grinding assembly 3. When suspension bracket 31 moves, it drives gear 3 36, mounted on its side, to move. A rack 3 47 is mounted on the side of the support rod 2 48 mounted on top of worktable 1. Gear 3 36 meshes with rack 3 47, causing gear 3 36 to rotate during movement. The third gear sprocket 36 is installed at the end of the first chain sprocket 33, which is installed on the side of the suspension frame 31. The first chain sprocket 33 and the second chain sprocket 34 installed at the end of the grinding head 32 are connected by a chain 35. When the first chain sprocket 33 rotates, it drives the second chain sprocket 34 to rotate through the chain 35, which in turn drives the grinding head 32 to rotate, cleaning and polishing the side of the steel plate placed on the placement plate 2. When the placement plate 2 moves, the connecting plate 23 installed on its surface drives the piston rod 62, which is connected to the limiting plate 65 installed at the end of the piston rod 62, to perform piston movement inside the material extraction cylinder 61 installed on one side of the worktable 1. The extraction pipe 63 mounted on the surface of the extraction cylinder 61 includes a first connecting pipe 631, a flexible corrugated pipe 632, and a second connecting pipe 633. The second connecting pipe 633 is inserted into the feed groove 21 opened at the top side of the placement plate 2. When the piston rod 62 moves, a negative pressure is generated inside the extraction cylinder 61, drawing the powder from the feed groove 21 into the extraction cylinder 61 through the extraction pipe 63. The discharge pipe 64 installed on one side of the extraction section 6 extends through to the storage box 7 with a door installed at the bottom of the workbench 1. The powder drawn into the extraction cylinder 61 is then discharged into the storage box 7 through the discharge pipe 64. One-way valves are installed at both the first connecting pipe 631 and the discharge pipe 64 to ensure that the extracted powder can only flow in one direction, preventing the powder from flowing back into the feed groove 21 or the extraction cylinder 61. A triangular plate 22 is installed in the feed trough 21 on the placement plate 2 to prevent the dust from falling out again after the placement plate 2 moves and pushes the dust into the feed trough 21.After cleaning, welding can proceed: After the above steps, the welding surface of the steel plate is automatically cleaned and polished, and the powder generated during cleaning is effectively collected. At this time, the welding work of the steel plate can be carried out. As for how to carry out the welding work, it is common knowledge in the field and is not related to the technical points of this solution, so it will not be described in detail here.
