Description

Technical Field

[0001] This invention relates to the field of submerged arc welding technology, and in particular to an automated submerged arc welding device based on laser tracking. Background Technology

[0002] Submerged arc welding is a method of welding workpieces by burning an electric arc under a layer of flux. This welding method can effectively protect the electric arc and the molten pool. Before welding, flux needs to be laid on the workpiece at the joint to be welded. Then, the welding head of the submerged arc welding machine embeds the welding wire into the flux. The welding wire is heated by the submerged arc welding machine. Under the action of heating, the end of the welding wire and the workpiece are locally melted to form a molten pool. The flux melts and fills the corresponding joint, thereby realizing the welding of two workpieces to each other. When laying flux, attention should be paid to the height and width of the flux pile. If the height of the flux pile is insufficient, it may lead to arc exposure, causing porosity or poor protection. The width of the flux pile should ensure that the welding area is completely covered to avoid porosity or lack of fusion defects. The current technology involves directly spreading flux onto the welding area through pipes during the movement of the welding machine. However, the flux does not gather after being spread, resulting in the width or height of the flux pile not meeting the welding requirements. This necessitates manual assistance by using a brush to sweep and gather the flux, which significantly impacts work efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing an automated submerged arc welding device based on laser tracking. This invention utilizes a convergence mechanism that allows the trigger rod to slide horizontally back and forth along the inclined surface of the inclined block as the roller drives the inclined block to rotate. This causes the floating frame to move the convergence plates back and forth, so that whenever two convergence plates approach each other, the convergence plates push the flux towards the middle weld seam. Compared to existing technologies that directly spread the flux onto the welding area through pipes, this device converges the spread flux, ensuring that the width and height of the weld pile meet welding requirements. This avoids the situation where the flux does not gather after being laid out, requiring manual assistance to sweep and gather it with a brush, greatly improving work efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automated submerged arc welding device based on laser tracking, comprising a frame, a bogie rotatably inserted into the bottom outer wall of the frame, a submerged arc welding head mounted on the outer wall of the bogie, a flux tank disposed on the outer wall of the bogie, a feeding pipe disposed at the bottom of the flux tank, a mounting frame welded to the bottom outer wall of the feeding pipe, a convergence mechanism and an auxiliary mechanism disposed on the mounting frame, the convergence mechanism comprising a roller rotatably inserted into the bottom outer wall of the mounting frame, the roller being in the same plane as the caster wheels, and several equidistantly distributed circumferentially inclined blocks disposed on the outer walls of both ends of the roller, the mounting... A pair of floating frames symmetrically distributed on both sides of the drum are slidably inserted into the outer wall of the frame. Each floating frame has a trigger rod welded to its outer wall to abut against the inclined block. A first spring is provided between the outer wall of each floating frame and the outer wall of the steering frame, and a bolt is rotatably inserted into the outer wall of each floating frame. A pair of slidable gathering plates symmetrically distributed on both sides of the drum are slidably inserted into the outer wall of the mounting frame. Each gathering plate is threaded onto the outer wall of the bolt. A baffle plate with the bottom end of the feed pipe abutting is welded to the top outer wall of each gathering plate. The gathering mechanism drives the two gathering plates to move back and forth, pushing the flux towards the middle weld.

[0005] Preferably, the bottom of the frame is provided with casters driven by an independent power source, a motor is installed on the top outer wall of the frame, the main shaft of the motor is fixed on the rotating shaft of the bogie, and a laser tracker is installed on one side outer wall of the bogie.

[0006] Preferably, a scraper is provided on the outer wall of the mounting frame near the welding head of the submerged arc welding machine, a pusher plate is slidably inserted into the outer wall of the mounting frame located between the two convergence plates, a connecting rod is rotatably inserted into the outer wall of each floating frame, and the outer wall of each connecting rod away from the floating frame is rotatably inserted into the outer wall of the pusher plate.

[0007] Preferably, the flux is pushed toward the scraper by the reciprocating movement of the pusher plate.

[0008] Preferably, the auxiliary mechanism includes a swing arm rotatably inserted into the outer wall of the top of the mounting frame, a sliding groove with equidistant circumferential distribution and connected end to end on the outer wall of the roller, a sliding column slidably inserted into the sliding groove on the outer wall of the swing arm near the roller, a retainer that can be attracted by a magnetic block slidably inserted into the inner wall of the flux box, and a feed port on the top of the flux box.

[0009] Preferably, a cleaning brush is installed on the outer wall of the end of the swing arm away from the roller, and a support rod extending to the bottom of the flux tank is welded to the outer wall of the end of the swing arm close to the roller, with a magnetic block fixed on the outer wall of the top end of the support rod.

[0010] Preferably, a slag discharge port is provided on one side of the outer wall of the flux box, an inclined sieve plate is installed on the outer wall of the retainer towards the slag discharge port, and a second spring is provided between the outer wall of the retainer and the bottom inner wall of the flux box.

[0011] Preferred configuration: The reciprocating swing of the lever drives the cleaning brush to clean the weld seam, while simultaneously changing the distance between the magnet and the cage.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through its gathering mechanism, enables the trigger rod to reciprocate horizontally along the inclined surface of the inclined block as the roller drives the inclined block to rotate. This causes the floating frame to reciprocate the gathering plate, and when two gathering plates approach each other, the gathering plate pushes the flux towards the middle weld seam. Compared to the existing technology of directly spreading the flux onto the welding area through pipes, this device gathers the spread flux, ensuring that the width and height of the weld pile meet the welding requirements. This avoids the situation where the flux does not gather after being spread, requiring manual assistance to sweep and gather it with a brush, greatly improving work efficiency.

[0013] 2. This invention utilizes bolts to change the distance between two gathering plates, so that as the distance between the two gathering plates changes, the distance between the two baffles also changes, thereby changing the degree of obstruction of the feed pipe by the baffles, and thus changing the amount of flux falling. This achieves the effect of adjusting the amount of flux falling according to the weld width, ensuring that the amount of flux is sufficient to cover the weld while avoiding flux waste, further improving the practicality of this device.

[0014] 3. This invention, through its auxiliary mechanism, enables the swing arm to reciprocate and oscillate the cleaning brush under the action of the sliding groove and sliding column when the drum rotates, thereby achieving the effect of cleaning the weld seam and improving the welding effect. At the same time, whenever the swing arm drives the magnetic block close to the retainer through the support rod, the retainer moves downward against the elastic force of the second spring under the magnetic force of the magnetic block. When the swing arm drives the magnetic block away from the retainer, the attraction force between the magnetic block and the retainer weakens, thereby causing the second spring to push the retainer upward and reset. This reciprocating motion causes the retainer to drive the sieve plate to move up and down, achieving the effect of sieving the flux and further improving the welding effect. The filtered welding slag and large particulate impurities can be discharged through the slag discharge port. Attached Figure Description

[0017] 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. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] See Figures 1 to 7As shown, an automated submerged arc welding device based on laser tracking includes a frame 1. A bogie 121 is rotatably inserted into the bottom outer wall of the frame 1. A submerged arc welding head 122 is mounted on the outer wall of the bogie 121. A flux tank 124 is provided on the outer wall of the bogie 121. A feeding pipe 127 is provided at the bottom of the flux tank 124. A mounting frame 128 is welded to the bottom outer wall of the feeding pipe 127. A convergence mechanism and an auxiliary mechanism are provided on the mounting frame 128. The convergence mechanism includes a roller 2 rotatably inserted into the bottom outer wall of the mounting frame 128. The roller 2 and the caster wheel 11 are in the same plane. Several equidistant circumferentially distributed inclined blocks 22 are provided on the outer walls of both ends of the roller 2. A pair of floating frames 3 symmetrically distributed on both sides of the roller 2 are slidably inserted into the outer wall of the mounting frame 128. A trigger that abuts against the inclined block 22 is welded to the outer wall of each floating frame 3. A first spring 32 is fitted on the outer wall of the trigger rod 31 between the outer wall of each floating frame 3 and the outer wall of the bogie 121. A bolt 33 is rotatably inserted into the outer wall of each floating frame 3. A pair of symmetrically distributed gathering plates 34 are slidably inserted into the outer wall of the mounting frame 128 on both sides of the roller 2. Each gathering plate 34 is fitted onto the outer wall of the bolt 33 by threaded engagement. A baffle 35 with the bottom end of the feed pipe 127 is welded to the top outer wall of each gathering plate 34. The two gathering plates 34 are driven to move back and forth by the gathering mechanism to push the flux toward the middle weld. The bottom of the frame 1 is equipped with a universal wheel 11 driven by an independent power source. A motor 12 is installed on the top outer wall of the frame 1. The main shaft of the motor 12 is fixed on the rotating shaft of the bogie 121. A laser tracker 123 is installed on one side outer wall of the bogie 121.

[0019] It should be noted that the caster 11 is driven by an independent power source and steering mechanism not shown in the figure. The laser tracker 123 can identify the weld seam through line laser and drive the entire device to track the weld seam through the caster 11. The above are all relatively mature existing technologies, which will not be described in detail here. The submerged arc welding machine welding head 122, laser tracker 123, flux box 124 and roller 2 are displaced in the same vertical plane, so that when the device tracks the weld seam, the weld seam can be located between the gathering plates 34 on both sides of the roller 2.

[0020] The side where the laser tracker 123 is located is the welding forward direction. A control valve (not shown in the figure) is installed between the flux tank 124 and the feed pipe 127. During welding, the control valve is opened, allowing the flux to fall through the feed pipe 127 between the two collecting plates 34. At the same time, as the entire device moves, the roller 2 rotates due to the friction between it and the workpiece. Under the action of the first spring 32, the trigger rod 31 is always in contact with the inclined block 22. As the roller 2 drives the inclined block 22 to rotate, the trigger rod 31 can move horizontally along the inclined surface of the inclined block 22. The sliding motion causes the trigger rod 31 to move the floating frame 3 synchronously, which in turn causes the floating frame 3 to move the gathering plate 34 back and forth. As a result, whenever the two gathering plates 34 approach each other, the gathering plates 34 push the flux toward the middle weld seam. Compared with the existing technology of directly spreading the flux onto the welding area through pipes, this device gathers the spread flux, ensuring that the width and height of the weld pile meet the welding requirements. This avoids the situation where the flux does not gather after being spread, requiring manual assistance to sweep and gather it with a brush, greatly improving work efficiency.

[0021] Furthermore, before laying the flux, the width of the flux can be adjusted according to the width of the weld. By rotating the bolts 33 on both sides, the distance between the two gathering plates 34 can be changed, thereby changing the width of the flux after it falls. This achieves the effect of adjusting the width of the subsequent flux pile, greatly improving the practicality of the device.

[0022] Simultaneously, as the distance between the two converging plates 34 changes, the distance between the two baffles 35 also changes, altering the degree of obstruction of the feed pipe 127 by the baffles 35, and consequently changing the flux drop. When the weld width increases, the distance between the two converging plates 34 is increased by adjusting the bolts 33, causing the two converging plates 34 to move the two baffles 35 further apart, thus reducing the degree of obstruction of the feed pipe 127 by the baffles 35, and increasing the flux drop. Similarly, when the weld width decreases, the two converging plates 34 move the two baffles 35 closer together, increasing the degree of obstruction of the feed pipe 127 by the baffles 35, and decreasing the flux drop. This achieves the effect of adjusting the flux drop according to the weld width, ensuring sufficient flux to cover the weld while avoiding flux waste, further improving the practicality of the device.

[0023] A scraper 129 is provided on the outer wall of the mounting frame 128 near the welding head 122 of the submerged arc welding machine. A pusher plate 4 is slidably inserted into the outer wall of the mounting frame 128 between the two gathering plates 34. A connecting rod 41 is rotatably inserted into the outer wall of each floating frame 3. The outer wall of each connecting rod 41 away from the floating frame 3 is rotatably inserted into the outer wall of the pusher plate 4. The flux is pushed towards the scraper 129 by the reciprocating movement of the pusher plate 4.

[0024] It should be noted that the distance between the scraper 129 and the weldment is the height of the flux pile. Whenever the two floating frames 3 move back and forth, the pusher plate 4 slides back and forth along the weld direction under the action of the connecting rod 41. When the floating frame 3 drives the two gathering plates 34 to approach each other, the pusher plate 4 pushes the flux between the two gathering plates 34 toward the scraper 129 under the action of the connecting rod 41, thereby increasing the flux height at the scraper 129. This increases the height of the flux pile when gathering the flux laying width, avoiding the situation where the height of the flux pile cannot meet the welding requirements, and further improving the practicality of the device. When the scraper 129 passes over the flux pile, it can scrape the excessively high flux pile to a suitable height, and the excess flux is continued to be pushed forward for subsequent weld laying, avoiding waste.

[0025] The auxiliary mechanism includes a swing rod 5 rotatably inserted into the top outer wall of the mounting bracket 128; equidistant circular grooves 21 connected end to end are provided on the outer wall of the roller 2; a sliding column 51 is provided on the outer wall of the swing rod 5 near the roller 2, which is slidably inserted into the groove 21; a retainer 61 that can be attracted by a magnetic block 54 is slidably inserted into the inner wall of the flux tank 124; a feed inlet 125 is provided on the top of the flux tank 124; a cleaning brush 52 is installed on the outer wall of the swing rod 5 away from the roller 2; and a swing rod 5 near the roller 2... A support rod 53 extending to the bottom of the flux tank 124 is welded to one end of the outer wall. A magnetic block 54 is fixed on the top outer wall of the support rod 53. A slag discharge port 126 is opened on one side of the outer wall of the flux tank 124. An inclined sieve plate 6 is installed on the outer wall of the retainer 61, which is inclined towards the slag discharge port 126. A second spring 62 is provided between the outer wall of the retainer 61 and the bottom inner wall of the flux tank 124. By the reciprocating swing of the swing rod 5, the cleaning brush 52 is driven to clean the weld. At the same time, the distance between the magnetic block 54 and the retainer 61 is changed.

[0026] It should be noted that the flux is added into the flux tank 124 through the inlet 125, and the inlet 125 can be connected to the flux recovery device built into the submerged arc welding machine through a pipeline to realize the recycling of flux.

[0027] When the drum 2 rotates, under the action of the slide groove 21 and the slide column 51, the swing rod 5 drives the cleaning brush 52 to swing back and forth, thereby achieving the effect of cleaning the weld seam and improving the welding effect. At the same time, whenever the swing rod 5 drives the magnetic block 54 to approach the retainer 61 through the support rod 53, the retainer 61 moves down against the elastic force of the second spring 62 under the magnetic force of the magnetic block 54. When the swing rod 5 drives the magnetic block 54 away from the retainer 61, the attraction between the magnetic block 54 and the retainer 61 weakens, thereby causing the second spring 62 to push the retainer 61 to move up and reset. This process repeats, causing the retainer 61 to drive the sieve plate 6 to move up and down, achieving the effect of screening the flux and further improving the welding effect. The filtered welding slag and large particle impurities can be discharged through the slag discharge port 126.

[0028] Working principle: The flux is added into the flux tank 124 through the feed port 125, and the feed port 125 is connected to the flux recovery device built into the submerged arc welding machine through a pipeline; The laser tracker 123 drives the entire device to track the weld seam; With the set-up gathering mechanism, as the whole device moves, the roller 2 rotates due to the friction between it and the welded part. Under the action of the first spring 32, the trigger rod 31 always abuts against the inclined block 22. As the roller 2 drives the inclined block 22 to rotate, the trigger rod 31 can slide back and forth horizontally along the inclined surface of the inclined block 22. The trigger rod 31 drives the floating frame 3 to move synchronously, thereby causing the floating frame 3 to drive the gathering plate 34 to move back and forth. Thus, whenever the two gathering plates 34 approach each other, the gathering plate 34 pushes the flux toward the middle weld. Compared with the existing technology of directly spreading the flux on the welding area through pipes, this device gathers the spread flux, so that the width and height of the weld pile can meet the welding requirements. It avoids the situation where the flux does not gather after being spread and requires manual assistance to sweep and gather it with a brush, which greatly improves the work efficiency. Simultaneously, as the distance between the two converging plates 34 changes, the distance between the two baffles 35 also changes, altering the degree of obstruction of the feed pipe 127 by the baffles 35, and consequently changing the flux drop. When the weld width increases, the distance between the two converging plates 34 is increased by adjusting the bolts 33, causing the two converging plates 34 to move the two baffles 35 away from each other, thus reducing the degree of obstruction of the feed pipe 127 by the baffles 35, and increasing the flux drop. Similarly, when the weld width decreases, the two converging plates 34 move the two baffles 35 closer to each other, increasing the degree of obstruction of the feed pipe 127 by the baffles 35, and decreasing the flux drop. This achieves the effect of adjusting the flux drop according to the weld width, ensuring sufficient flux to cover the weld while avoiding flux waste, further improving the practicality of the device. By means of an auxiliary mechanism, when the roller 2 rotates, the swing arm 5 drives the cleaning brush 52 to swing back and forth under the action of the slide groove 21 and the slide column 51, thereby achieving the effect of cleaning the weld seam and improving the welding effect. At the same time, whenever the swing arm 5 drives the magnetic block 54 to approach the retainer 61 through the support rod 53, the retainer 61 moves down against the elastic force of the second spring 62 under the magnetic force of the magnetic block 54. When the swing arm 5 drives the magnetic block 54 away from the retainer 61, the attraction between the magnetic block 54 and the retainer 61 weakens, thereby causing the second spring 62 to push the retainer 61 to move up and reset. This process is repeated, causing the retainer 61 to drive the sieve plate 6 to move up and down, achieving the effect of screening the flux and further improving the welding effect. The filtered welding slag and large particle impurities can be discharged through the slag discharge port 126.
