Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a gate arc welding device. Background Technology

[0002] Arc welding is a welding method that uses the heat of an electric arc generated between an electrode and a workpiece to melt metals and form a joint. The working principle is to convert electrical energy into heat energy, so that the arc zone generates high temperature, melting metal materials such as steel and aluminum alloys. After cooling, a strong joint is formed. Arc welding can be divided into shielded metal arc welding, gas shielded welding, and tungsten inert gas welding. When manufacturing gates, carbon dioxide gas shielded welding is usually required. During operation, the user holds the welding torch and maintains a stable posture to weld the seam.

[0003] In the current gate welding process, the length of a single weld seam is usually several meters or even more. Users hold the welding gun for a long time, and their arms need to bear the weight continuously and maintain stability, which can easily lead to muscle fatigue. Especially in the welding of long weld seams, fatigue can directly cause the movement speed to be fast or slow, resulting in fluctuations in the amount of deposited metal, which in turn produces defects such as porosity, slag inclusions and incomplete penetration, leading to a decline in welding quality.

[0004] To address the above problems, a gate arc welding device is proposed. Summary of the Invention

[0012] Furthermore, the compensation component includes two connecting pipes that are relatively connected to the welding torch.

[0019] During the mobile welding process, when the welding torch exhibits uneven speed, the compensation component can perform dynamic speed compensation, ensuring that the welding torch always maintains a uniform welding speed.

[0020] When performing dynamic speed compensation, by adjusting the component settings, the flow rate of carbon dioxide shielding gas discharged from the welding torch can be kept consistent, thereby ensuring the stability of the welding protection effect.

[0021] By using the drive component in conjunction with the cleaning component, the process of drawing in gas, compressing the gas, and then expelling the compressed gas is repeated in a cycle, thereby blowing away impurities or particles in the path and improving the welding quality.

[0044] 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.

[0045] To address the technical problem of muscle fatigue and reduced welding quality caused by prolonged hand-holding of the welding torch, such as... Figures 1-20As shown, the following preferred technical solutions are provided:

[0046] An arc welding device for a gate includes a welding machine 1. An exhaust assembly 2 is located on one side of the welding machine 1, and one end of the exhaust assembly 2 is connected to a welding torch 3. A controller is installed inside the welding machine 1 to control various electrical components. The controller is existing technology and is not shown in the diagram for ease of illustration. The welding machine 1 provides power to the welding torch 3 and continuously feeds welding wire for gate welding, thus facilitating gate welding. The exhaust assembly 2 continuously discharges carbon dioxide gas, providing protection and preventing oxidation of the molten pool, thereby improving weld quality. Two fixing sleeves 4 are fixedly installed on the outer ring of the welding torch 3, with the two fixing sleeves 4 facing each other... Several inclined blocks 41 are provided, and sliding components 5 are slidably mounted on the outer wall of the inclined blocks 41. According to welding requirements, the welding torch 3 and the two fixed sleeves 4 are adjusted to the required angle, and the inclined blocks 41 are pressed down by the sliding components 5 for positioning. This allows for adjustment of the welding angle, thereby improving adaptability. A fixed component 6 is slidably mounted on the outer wall of the sliding component 5, and a moving component 7 is fixedly mounted on one side of the fixed component 6. The moving component 7 allows the user to easily push the fixed component 6 and the welding torch 3 to move and weld, thus avoiding muscle fatigue caused by prolonged hand-holding of the welding torch 3, which affects welding quality. Figure 2 As shown, an acceleration sensor 8 is installed on one side of the moving component 7. The acceleration sensor 8 can detect whether the movement of the moving component 7 is uniform. The initial uniform speed value can be specifically set by the controller. Two sets of compensation components 9 are connected to each other on the outer wall of the welding torch 3. Both sets of compensation components 9 are connected to the fixed component 6. An adjustment component 10 is provided inside the welding torch 3.

[0047] During use, the user pushes the fixed component 6, which, in conjunction with the moving component 7, causes the welding torch 3 to move at a constant speed along the weld seam, thus uniformly welding the gate. When the acceleration sensor 8 detects that the moving speed of the welding torch 3 has increased or decreased, the controller triggers the compensation component 9 to respond, generating a force in the same or opposite direction as the movement, causing the welding torch 3 to decelerate or accelerate. During this process, the welding torch 3 drives the sliding component 5 to roll within the fixed component 6, thereby maintaining the welding torch 3 at a constant speed and performing dynamic speed compensation to improve welding quality. During dynamic speed compensation, gas flow fluctuations may occur. These fluctuations can be addressed by adjusting the settings of component 10. The system ensures that the flow rate of carbon dioxide shielding gas discharged from the welding torch 3 remains consistent, thereby guaranteeing a stable welding protection effect. A drive component 20 is provided on one side of the sliding component 5, and a cleaning component 30 is provided on the other side of the drive component 20. The cleaning component 30 is located on the side of the fixed component 6. During the movement of the moving component 7, impurities or particles may appear in the path. When these particles come into contact, they can easily cause the welding torch 3 to vibrate, thus affecting the welding quality. By using the drive component 20 in conjunction with the cleaning component 30, the gas can be compressed after pumping and then sprayed out. This cycle facilitates the removal of impurities or particles in the path, thereby improving the welding quality.

[0048] The outer wall of the welding torch 3 is equipped with a swing component 40. Depending on the welding requirements, in case 1, the welding torch 3 needs to maintain a constant speed. In this case, the swing component 40 is connected to the sliding component 5 to fix the position of the welding torch 3 and prevent the welding torch 3 from shifting during the welding process. In case 2, the welding torch 3 needs to swing back and forth while moving at a constant speed. In this case, the swing component 40 is connected to the drive component 20 to clean impurities or particles on the moving path and drive the welding torch 3 to swing back and forth, further improving the welding effect and the practicality of the device, while also facilitating the switching of different welding modes.

[0049] like Figures 1-2 , Figure 5 and Figure 8 As shown, the gas outlet assembly 2 includes a carbon dioxide gas tank 21 disposed on one side of the welding machine 1. One end of the carbon dioxide gas tank 21 is connected to a gas outlet pipe 22, and one end of the gas outlet pipe 22 is connected to the gas inlet of the booster. The booster is installed inside the welding machine 1. The booster is existing technology and is not shown in the figure for ease of demonstration. The gas outlet of the booster is connected to a first hose 23, and one end of the first hose 23 is connected to the welding torch 3.

[0050] like Figure 6 , Figure 9 , Figure 12 and Figures 14-20 As shown, the sliding assembly 5 includes a first half gear 51 and a second half gear 52 slidably connected to the outer ring of the fixed sleeve 4. The inclined block 41 of the fixed sleeve 4 is engaged with the teeth of the first half gear 51 and the second half gear 52. The inclined block 41 is slidably connected to the first half gear 51 and the second half gear 52, and can slide after positioning. At the same time, the inclined block 41, the first half gear 51 and the second half gear 52 are all made of high wear-resistant materials, and a lubricating medium is added during operation to reduce wear during sliding. T-shaped sliders 53 are fixedly connected to the outer walls of the first half gear 51 and the second half gear 52. Several first rollers 54 and second rollers 55 are rotatably connected to the two T-shaped sliders 53 respectively. A fixed rod 56 is fixedly connected to one side of the T-shaped slider 53, and a first fixed shaft 57 is fixedly connected to one side of the fixed rod 56.

[0051] like Figure 2 , Figures 5-6 , Figures 8-10 , Figure 14 and Figure 16As shown, the fixing component 6 includes a U-shaped plate 61 that is rollably connected to the first roller 54, a pressure plate 62 that is rollably connected to the outer wall of the second roller 55, a T-shaped groove 63 that is provided on both the U-shaped plate 61 and the pressure plate 62, a T-shaped slider 53 that is slidably connected to the T-shaped groove 63, mounting blocks 64 that are fixedly connected to both sides of the pressure plate 62, a screw 65 that is provided on one side of the mounting block 64, the screw 65 passing through the mounting block 64 and threadedly connected to the U-shaped plate 61, and a push rod 66 that is fixedly connected to one side of the pressure plate 62.

[0052] like Figures 2-3 , Figure 5 and Figure 7 As shown, the movable component 7 includes connecting rods 71 ​​fixedly connected to both sides of the U-shaped plate 61. A sliding rod 72 is fixedly connected to one end of the connecting rod 71. A support rod 73 is slidably connected to the outer wall of the sliding rod 72. A fixed plate 74 is fixedly connected to the outer wall of the support rod 73. A lifting plate 75 is fixedly connected to the outer wall of the connecting rod 71. An electric push rod 76 is installed on the top of the lifting plate 75. The movable end of the electric push rod 76 is fixedly connected to the fixed plate 74. A movable wheel 77 is rotatably connected inside the support rod 73. The movable wheel 77 is made of polyurethane and can absorb small vibrations. An acceleration sensor 8 is installed on one side of the fixed plate 74. By extending and retracting the electric push rod 76, the lifting plate 75 is raised and lowered. At this time, the sliding rod 72 slides inside the support rod 73, thereby facilitating the adjustment of the working height of the welding torch 3.

[0053] like Figure 2 , Figure 5 , Figure 8 , Figure 10 , Figure 13 and Figure 19 As shown, the compensation component 9 includes two connecting pipes 91 that are connected to the welding torch 3. One end of each connecting pipe 91 is connected to a first proportional valve 92. One end of the first proportional valve 92 is connected to a sliding sleeve 93. A connecting ring 94 is fixedly connected inside the sliding sleeve 93. A first spring 95 is fixedly connected to one side of the connecting ring 94, and a sliding column 96 is fixedly connected to the other end of the first spring 95. The sliding column 96 is slidably connected to the sliding sleeve 93. The sliding column 96 and the sliding sleeve 93 are sealed and fitted together to prevent carbon dioxide leakage and affect the effect of dynamic speed compensation. A U-shaped connecting plate 97 is fixedly connected to one side of the U-shaped plate 61, and one end of the sliding column 96 is fixedly connected to the U-shaped connecting plate 97.

[0054] like Figures 10-12As shown, the regulating component 10 includes a circular plate 101 fixedly connected inside the welding torch 3. A wire feeding tube is provided inside the circular plate 101 for conveying welding wire. A second proportional valve 102 is connected to one side of the circular plate 101. A flow sensor 103 is installed inside the welding torch 3. The flow sensor 103 is used to detect the flow rate of carbon dioxide shielding gas. When the compensation component 9 is activated, causing fluctuations in the flow rate of shielding gas, the controller changes the opening degree of the second proportional valve 102, thereby controlling the output flow rate of carbon dioxide shielding gas and ensuring that the flow rate of carbon dioxide shielding gas discharged from the welding torch 3 remains consistent.

[0055] During use, the welding torch 3 and the two fixed sleeves 4 are adjusted to the required welding angle according to the welding requirements. The first half gear 51 and the second half gear 52 are connected to the inclined blocks 41 on the two fixed sleeves 4. At this time, the screw 65 is tightened to fix the U-shaped plate 61 and the pressure plate 62, so as to facilitate the adjustment of the welding angle. When welding is required, the user holds and pushes the push rod 66 at a constant speed. With the help of the moving wheel 77, the U-shaped plate 61, the pressure plate 62, the sliding component 5 and the welding torch 3 can move at a constant speed along the weld seam, so as to weld the gate evenly. During the constant speed movement, the opening of the two first proportional valves 92 is centered. At the same time, the welding torch 3 is subjected to the elastic force of the two first springs 95, so that the T-shaped slider 53 and the welding torch 3 are kept in the middle position of the U-shaped plate 61 and the pressure plate 62.

[0056] When the accelerometer 8 detects that the moving speed of the welding torch 3 has increased, the controller increases the opening of the first proportional valve 92 on the side with the same direction of movement. At this time, the carbon dioxide gas impacts the sliding column 96, and the resulting reaction force causes the sliding sleeve 93 to slide on the sliding column 96, which stretches the first spring 95 on the connecting ring 94. The opening of the first proportional valve 92 on the side with the same direction of movement decreases, which compresses the first spring 95 on the other side of the connecting ring 94. This causes the welding torch 3 to move the fixed sleeve 4, the first half gear 51, the second half gear 52, the T-shaped slider 53, the first roller 54, and the second roller 55. The first roller 54 and the second roller 55 roll in the T-shaped groove 63 until the moving speed of the welding torch 3 gradually returns to the initially set uniform speed value. During the dynamic speed compensation process, the opening of the two first proportional valves 92 is dynamically adjusted according to the moving speed of the welding torch 3, in conjunction with the accelerometer 8 and the controller, so as to keep the welding torch 3 at a constant speed and perform dynamic speed compensation, thereby improving the welding quality.

[0057] When the accelerometer 8 detects that the moving speed of the welding torch 3 has slowed down, the controller increases the opening of the first proportional valve 92 on the opposite side of the movement direction, which is the opposite of the operation when the welding torch 3 speed has increased. This will not be elaborated further. The first hose 23 is made of lightweight material. During welding, the first hose 23 is neatly arranged. During the dynamic speed compensation process, the impact force of the airflow can overcome the resistance of the first spring 95 and the first hose 23. During the welding process, the flow sensor 103 detects the flow rate of the carbon dioxide shielding gas. When the compensation component 9 is activated, causing fluctuations in the shielding gas flow rate, the controller changes the opening of the second proportional valve 102 to ensure that the flow rate of the carbon dioxide shielding gas discharged from the welding torch 3 remains consistent, thus ensuring the stability of the welding protection effect.

[0058] To address the technical problem of difficulty in cleaning impurities and particles along the welding path during welding, such as Figures 2-6 , Figure 8 and Figures 14-20 As shown, the following preferred technical solutions are provided:

[0059] like Figure 6 , Figures 15-18 and Figure 20 As shown, the drive assembly 20 includes a first L-shaped mounting plate 201 fixedly connected to one side of the T-shaped slider 53. A motor 202 is mounted on one side of the first L-shaped mounting plate 201. A rotating plate 203 is fixedly connected to the output end of the motor 202. A second fixed shaft 204 is rotatably connected inside the rotating plate 203. The outer walls of the first fixed shaft 57 and the second fixed shaft 204 are both provided with slots. A second L-shaped mounting plate 205 is fixedly connected to the top of the first L-shaped mounting plate 201.

[0060] like Figures 2-6 , Figure 8 , Figure 14 and Figures 18-20As shown, the cleaning assembly 30 includes a cylinder 301 fixedly connected to the second L-shaped mounting plate 205. A connecting rod 302 is fixedly connected to the outer ring of the second fixed shaft 204. A lifting rod 303 is rotatably connected to one end of the connecting rod 302. A piston 304 is fixedly connected to one end of the lifting rod 303. The piston 304 is slidably connected to the cylinder 301. A first one-way valve 305 and a second hose 306 are respectively connected to the top of the cylinder 301. The second hose 306 is fixedly connected to two pressure plates 62. A second one-way valve 307 is connected to one end of the second hose 306. The second one-way valve 307 is installed on one side of the support rod 73. The opening pressure of the second one-way valve 307 is greater than that of the first one-way valve 305, thereby facilitating better air intake of the first one-way valve 305 and also facilitating compression. After the gas reaches a suitable pressure, it is discharged through the second one-way valve 307, which improves the effect of cleaning impurities or particles in the path. Before welding, the motor 202 is turned on to drive the rotating plate 203 to rotate, which drives the lifting rod 303 to pull down and push the piston 304 up and down, so that the second hose 306 stores enough air at a certain pressure, so that the compressed gas can be discharged directly when welding begins. One end of the second one-way valve 307 is connected to the air outlet pipe 308. The air outlet pipe 308 has a spiral groove 309. The spiral groove 309 can make the sprayed gas form a spiral airflow, which enhances the impact force and coverage of the airflow, thereby more efficiently blowing away impurities or particles in the moving path, avoiding the impact of impurity residue on the stable movement of the welding torch 3, and further improving the welding quality.

[0061] like Figures 5-6 , Figures 14-15 and Figures 18-20 As shown, the swing assembly 40 includes a support frame 401 fixedly connected to the outer wall of the welding torch 3. A rotating shaft 402 is fixedly connected inside the support frame 401. A drive plate 403 is rotatably connected to the outer ring of the rotating shaft 402. Two sliding plates 404 are slidably connected inside the drive plate 403. A second spring 405 is fixedly connected to one side of each of the two sliding plates 404, and the other end of the second spring 405 is fixedly connected to the inner wall of the drive plate 403. An electromagnet 406 is installed on the inner wall of the drive plate 403. A magnet 407 is fixedly connected to one side of each of the two sliding plates 404, and a locking rod 408 is fixedly connected to the other side of each of the two sliding plates 404.

[0062] During the movement of the moving wheel 77, impurities or particles may appear in the path. When the moving wheel 77 contacts the object, it can easily cause the welding torch 3 to bounce, thus affecting the welding quality. Therefore, during welding, the controller causes the motor 202 to drive the rotating plate 203 to rotate, which in turn drives the second fixed shaft 204 to rotate, causing the lifting rod 303 to move and repeatedly pull down and push up the piston 304. During the process of pulling down the piston 304, gas enters the cylinder 301 through the first one-way valve 305. During the process of pushing up the piston 304, the piston 304 compresses the gas in the cylinder 301, causing the gas in the second hose 306 to be compressed. When the compressed gas reaches the opening pressure of the second one-way valve 307, the gas is discharged through the second one-way valve 307 and the air outlet pipe 308. This cycle of pumping and spraying gas can continuously pump and compress the gas, and then spray the compressed gas out, thereby blowing away impurities or particles in the path and improving the welding quality.

[0063] Depending on the welding requirements, in case 1, the welding torch 3 needs to maintain a constant speed. In this case, connecting the two locking rods 408 to the slots of the first fixed shaft 57 can fix the sliding component 5, the swing component 40 and the welding torch 3, and prevent the welding torch 3 from shifting during the welding process.

[0064] Scenario 2: The welding torch 3 needs to reciprocate while moving at a constant speed. The controller causes the electromagnet 406 to attract the magnet 407 and compress the second spring 405, causing the locking rod 408 to disengage from the slot of the first fixed shaft 57. The user then pushes the drive plate 403, causing it to slide on the rotating shaft 402. At this point, the drive plate 403 disengages from the first fixed shaft 57. The controller then causes the motor 202 to rotate the rotating plate 203, which in turn rotates the second fixed shaft 204 until it reaches the switching position. Afterward, the rotating plate 203 is rotated and then pushed back to its original position, allowing the second fixed shaft 204 to insert into the drive plate 402. 3. At this time, the controller causes the electromagnet 406 to stop attracting the magnet block 407 and resets it through the second spring 405. This causes the locking rod 408 to engage with the slot of the second fixed shaft 204. During welding, the rotation of the second fixed shaft 204 drives the drive plate 403 to move, which in turn drives the rotating shaft 402, the support frame 401, and the welding torch 3 to swing back and forth. At this time, the inclined block 41 slides in the first half gear 51 and the second half gear 52. This allows the welding torch 3 to swing back and forth while cleaning impurities or particles on the moving path, further improving the welding effect and the practicality of the device. It can be quickly switched and is convenient to adapt to different welding modes.
