Description

Technical Field

[0001] The present invention relates to the technical field of welding, in particular to a gate arc welding device. Background Art

[0002] Arc welding is a welding method that uses the arc heat generated between the electrode and the workpiece to melt the metal for connection. The working principle is to convert electrical energy into thermal energy, generate high temperature in the arc zone, melt metal materials such as steel and aluminum alloy, and form a strong joint after cooling. Arc welding can be divided into stick arc welding, gas shielded welding and tungsten inert gas welding. When producing and processing gates, carbon dioxide gas shielded welding is usually required for welding. During operation, the user holds the welding gun and maintains a stable posture to weld the weld.

[0003] During the current gate welding process, the length of a single weld is usually several meters or even longer. The user holds the welding gun for a long time, and the arm needs to bear the weight continuously and maintain stability, which can easily lead to muscle fatigue. Especially in the welding of long welds, fatigue will directly cause the movement speed to increase or decrease suddenly, resulting in fluctuations in the amount of deposited metal, and then causing defects such as porosity, slag inclusions and incomplete penetration, resulting in a decline in welding quality.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to solve the technical problem that the user holds the welding gun 3 for a long time, causing muscle fatigue and reducing welding quality, such as Figures 1-20 As shown, the following preferred technical solutions are provided: A gate arc welding device includes a welding machine 1, a gas outlet component 2 is provided on one side of the welding machine 1, and a welding gun 3 is connected to one end of the gas outlet component 2. A controller is provided in the welding machine 1, which can control various electrical devices. The controller is a prior art and is not shown in the figure for the convenience of display. The welding machine 1 can power the welding gun 3 and continuously deliver the welding wire for gate welding, thereby facilitating the welding of the gate. The gas outlet component 2 continuously discharges carbon dioxide gas, which can provide protection and prevent the molten pool metal from being oxidized, thereby improving the quality of the weld. Two fixed sleeves 4 are fixed on the outer ring of the welding gun 3, and the two fixed sleeves 4 are relative to each other. There are several inclined blocks 41, and the outer wall of the inclined block 41 is slidingly provided with a sliding component 5. According to the welding requirements, the welding gun 3 and the two fixed sleeves 4 are adjusted to the required angle, and the inclined block 41 is pressed down by the sliding component 5 for positioning, so that the welding angle can be adjusted to improve the adaptability. The outer wall of the sliding component 5 is slidingly provided with a fixed component 6, and a moving component 7 is fixedly provided on one side of the fixed component 6. The moving component 7 can facilitate the user to push the fixed component 6 and the welding gun 3 for mobile welding, thereby avoiding the user holding the welding gun 3 for a long time, causing muscle fatigue and affecting the 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 through the controller. Two groups of compensation components 9 are relatively connected to the outer wall of the welding gun 3. The two groups of compensation components 9 are both connected to the fixed component 6. An adjustment component 10 is provided in the welding gun 3.

[0025] During use, the user pushes the fixed component 6 and cooperates with the moving component 7 to make the welding gun 3 move at a constant speed along the weld, thereby uniformly welding the gate. When the acceleration sensor 8 detects that the moving speed of the welding gun 3 becomes faster or slower, the controller makes the compensation component 9 respond and generates a force in the same or opposite direction of movement, so that the welding gun 3 slows down or accelerates. During the process, the welding gun 3 drives the sliding component 5 to roll in the fixed component 6, so as to keep the welding gun 3 at a constant speed at all times and perform dynamic speed compensation, thereby improving the welding quality. During the dynamic speed compensation process, gas flow fluctuations will occur. By adjusting the setting of the component 10, The flow rate of carbon dioxide shielding gas discharged from the welding gun 3 can be kept consistent, thereby ensuring the stability of the welding protection effect. A driving component 20 is provided on one side of the sliding component 5, and a cleaning component 30 is provided on one side of the driving component 20. The cleaning component 30 is provided on one side of the fixed component 6. When the moving component 7 is moving, there will be impurities or particles on the path. When in contact, it is easy to cause the welding gun 3 to bump, thereby affecting the welding quality. By cooperating with the driving component 20 and the cleaning component 30, the gas can be compressed after pumping, and then the compressed gas can be ejected. Such a cycle makes it convenient to blow away the impurities or particles on the path, thereby improving the welding quality.

[0026] The outer wall of the welding gun 3 is provided with a swing assembly 40. Depending on the welding requirements, situation 1: the welding gun 3 needs to maintain uniform motion. At this time, the swing assembly 40 is connected to the sliding assembly 5 to fix the position of the welding gun 3 to avoid displacement of the welding gun 3 during the moving welding process. Situation 2: the welding gun 3 needs to swing back and forth while moving at a uniform speed. At this time, the swing assembly 40 is connected to the driving assembly 20. It can drive the welding gun 3 to swing back and forth while cleaning impurities or particulate matter on the moving path, further improving the welding effect and the practicality of the device, and facilitating switching between different welding modes.

[0027] like Figure 1-Figure 2 、 Figure 5 and Figure 8 As shown, the gas outlet assembly 2 includes a carbon dioxide gas tank 21 arranged on one side of the welding machine 1, one end of the carbon dioxide gas tank 21 is connected to an outlet pipe 22, one end of the outlet pipe 22 is connected to the air inlet of the booster, and the booster is installed in the welding machine 1. The booster is a prior art and is not shown in the figure for the convenience of display. The air outlet of the booster is connected to a first hose 23, and one end of the first hose 23 is connected to the welding gun 3.

[0028] 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 that are slidably connected to the outer ring of the fixed sleeve 4. The inclined block 41 of the fixed sleeve 4 is matched with the gear 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 lubricating medium is added during operation to reduce the wear generated during sliding. The outer walls of the first half gear 51 and the second half gear 52 are fixedly connected with a T-shaped slider 53, and the two T-shaped sliders 53 are respectively rotatably connected with a plurality of first rollers 54 and second rollers 55. One side of the T-shaped slider 53 is fixedly connected to a fixing rod 56, and one side of the fixing rod 56 is fixedly connected to a first fixed shaft 57.

[0029] like Figure 2 、 Figure 5-Figure 6 、 Figures 8-10 、 Figure 14 and Figure 16 As shown, the fixing assembly 6 includes a U-shaped plate 61 that is rollingly connected to the first roller 54, and a pressure plate 62 is rollingly connected to the outer wall of the second roller 55. The U-shaped plate 61 and the pressure plate 62 are both provided with a T-shaped groove 63, and the T-shaped slider 53 is slidingly connected to the T-shaped groove 63. Both sides of the pressure plate 62 are fixedly connected to mounting blocks 64, and a screw 65 is provided on one side of the mounting block 64. The screw 65 passes through the mounting block 64 and is threadedly connected to the U-shaped plate 61, and a push rod 66 is fixedly connected to one side of the pressure plate 62.

[0030] like Figure 2-Figure 3 、 Figure 5 and Figure 7 As shown, the moving assembly 7 includes a connecting rod 71 fixedly connected to both sides of the U-shaped plate 61, one end of the connecting rod 71 is fixedly connected to a sliding rod 72, the outer wall of the sliding rod 72 is slidably connected to a support rod 73, the outer wall of the support rod 73 is fixedly connected to a fixed plate 74, the outer wall of the connecting rod 71 is fixedly connected to a lifting plate 75, and 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, and a moving wheel 77 is rotatably connected to the support rod 73. The moving wheel 77 is made of polyurethane and can absorb small vibrations. The acceleration sensor 8 is installed on one side of the fixed plate 74, and the electric push rod 76 is extended and retracted to drive the lifting plate 75 to rise and fall. At this time, the sliding rod 72 slides in the support rod 73, so as to facilitate the adjustment of the use height of the welding gun 3.

[0031] like Figure 2 、 Figure 5 、 Figure 8 、 Figure 10 、 Figure 13 and Figure 19 As shown, the compensation assembly 9 includes two connecting pipes 91 relatively connected to the welding gun 3, one end of the two connecting pipes 91 are 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, one side of the connecting ring 94 is fixedly connected to a first spring 95, and the other end of the first spring 95 is fixedly connected to a sliding column 96, the sliding column 96 is slidably connected to the sliding sleeve 93, the sliding column 96 is sealed and fitted with the sliding sleeve 93, which can avoid 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.

[0032] like Figure 10-12 As shown, the adjustment component 10 includes a circular plate 101 fixedly connected to the welding gun 3, a wire feeding tube is provided in the circular plate 101 for conveying welding wire, a second proportional valve 102 is connected to one side of the circular plate 101, and a flow sensor 103 is installed in the welding gun 3. The flow sensor 103 is used to detect the flow of carbon dioxide shielding gas. When the compensation component 9 is started, causing the flow of shielding gas to fluctuate, the controller changes the opening of the second proportional valve 102, thereby controlling the output flow of carbon dioxide shielding gas, so that the flow of carbon dioxide shielding gas discharged from the welding gun 3 is always consistent.

[0033] During use, according to welding requirements, the welding gun 3 and the two fixed sleeves 4 are adjusted to the required welding angle, and the first half gear 51 and the second half gear 52 are connected to the inclined blocks 41 on the two fixed sleeves 4 accordingly. 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, and cooperates with the moving wheel 77 to drive the U-shaped plate 61, the pressure plate 62, the sliding assembly 5 and the welding gun 3 to move at a constant speed along the weld, thereby uniformly welding the gate. During the uniform movement, the openings of the two first proportional valves 92 are centered, and at the same time, the welding gun 3 is subjected to the elastic force of the two first springs 95, so that the T-shaped slider 53 and the welding gun 3 are maintained in the middle position between the U-shaped plate 61 and the pressure plate 62.

[0034] When the acceleration sensor 8 detects that the moving speed of the welding gun 3 is increasing, the controller increases the opening of the first proportional valve 92 on the side in the same direction of movement. At this time, the carbon dioxide gas impacts the sliding column 96, generating a reaction force that causes the sliding sleeve 93 to slide on the sliding column 96, causing the connecting ring 94 to stretch the first spring 95. The opening of the first proportional valve 92 on the side in the same direction of movement decreases, causing the connecting ring 94 on the other side to compress the first spring 95, so that the welding gun 3 drives 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 to move, causing the first roller 54 and the second roller 55 to roll in the T-shaped slide 63 until the moving speed of the welding gun 3 gradually returns to the initially set uniform speed value. During the process of dynamic speed compensation, the openings of the two first proportional valves 92 are dynamically adjusted according to the moving speed of the welding gun 3 in conjunction with the acceleration sensor 8 and the controller, so as to keep the welding gun 3 at a constant speed at all times, perform dynamic speed compensation, and thus improve welding quality.

[0035] When the acceleration sensor 8 detects that the moving speed of the welding gun 3 slows down, the controller increases the opening of the first proportional valve 92 on the side opposite to the movement direction, which is the opposite of the operation process when the speed of the welding gun 3 is detected to be faster. I will not elaborate on it here. The first hose 23 is made of lightweight material. During welding, the first hose 23 is arranged neatly. 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 rate of the carbon dioxide shielding gas is detected by the flow sensor 103. When the compensation component 9 is started, causing the shielding gas flow rate to fluctuate, the controller changes the opening of the second proportional valve 102 to make the carbon dioxide shielding gas flow rate discharged from the welding gun 3 always consistent, thereby ensuring the stability of the welding protection effect.

[0036] In order to solve the technical problem that it is not easy to clean the impurities and particles on the welding path, such as Figure 2-Figure 6 、 Figure 8 and Figures 14-20As shown, the following preferred technical solutions are provided: like Figure 6 、 Figure 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 installed 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, and the outer walls of the first fixed shaft 57 and the second fixed shaft 204 are both provided with card grooves, and a second L-shaped mounting plate 205 is fixedly connected to the top of the first L-shaped mounting plate 201.

[0037] like Figure 2-Figure 6 、 Figure 8 、 Figure 14 and Figures 18-20 As shown, the cleaning assembly 30 includes a cylinder 301 fixedly connected to the second L-shaped mounting plate 205, a connecting rod 302 fixedly connected to the outer ring of the second fixed shaft 204, one end of the connecting rod 302 is rotatably connected to the lifting rod 303, one end of the lifting rod 303 is fixedly connected to the piston 304, the piston 304 is slidably connected to the cylinder 301, the top of the cylinder 301 is respectively connected to the first one-way valve 305 and the second hose 306, the second hose 306 is fixedly connected to the two pressure plates 62, and one end of the second hose 306 is connected to the second one-way valve 307, 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 particulate matter on the path. Before welding, the motor 202 is turned on to drive the rotating plate 203 to rotate, and the lifting rod 303 is driven to pull down and push up the piston 304 back and forth, so that air with sufficient pressure is pre-stored in the second hose 306, which is convenient for directly discharging the compressed gas at the beginning of welding. One end of the second one-way valve 307 is connected to the air outlet pipe 308, and a spiral groove 309 is provided in the air outlet pipe 308. The spiral groove 309 can make the ejected gas form a spiral airflow, enhance the impact force and coverage of the airflow, thereby more efficiently blowing away impurities or particulate matter on the moving path, avoiding impurity residues affecting the stable movement of the welding gun 3, and further improving the welding quality.

[0038] like Figure 5-Figure 6 、 Figure 14-15 and Figures 18-20As shown, the swing assembly 40 includes a support frame 401 fixedly connected to the outer wall of the welding gun 3, a rotating shaft 402 is fixedly connected inside the support frame 401, the outer ring of the rotating shaft 402 is rotatably connected to a driving plate 403, and two slides 404 are relatively slidably connected inside the driving plate 403, one side of the two slides 404 are fixedly connected to a second spring 405, and the other end of the second spring 405 is fixedly connected to the inner wall of the driving plate 403, an electromagnet 406 is installed on the inner wall of the driving plate 403, one side of the two slides 404 are fixedly connected to a magnet block 407, and the other side of the two slides 404 are fixedly connected to a clamping rod 408.

[0039] When the moving wheel 77 is moving, there will be impurities or particles on the path. When the moving wheel 77 contacts, it is easy to cause the welding gun 3 to bump, thereby affecting the welding quality. Therefore, during welding, the controller is used to make the motor 202 drive the rotating plate 203 to rotate, drive the second fixed shaft 204 to rotate, and make the lifting rod 303 move, pulling down and pushing up the piston 304 back and forth. In the process of pulling down the piston 304, the gas enters the cylinder 301 through the first one-way valve 305. In the process of pushing up the piston 304, the gas in the cylinder 301 is squeezed by the piston 304, so that the gas in the second hose 306 is compressed. When the compressed gas reaches the opening pressure of the second one-way valve 307, the gas is discharged from the air outlet pipe 308 through the second one-way valve 307. Such a cycle of pumping and jetting can compress the gas after continuous pumping, and then spray the compressed gas out, thereby blowing away impurities or particles on the path, thereby improving the welding quality.

[0040] Depending on the welding requirements, situation 1: the welding gun 3 needs to maintain uniform motion. At this time, the two clamping rods 408 are connected to the clamping groove of the first fixed shaft 57, which can fix the sliding assembly 5, the swing assembly 40 and the welding gun 3 to avoid displacement of the welding gun 3 during the moving welding process.

[0041] Case 2: The welding gun 3 needs to swing back and forth while moving at a constant speed. The controller makes the electromagnet 406 attract the magnet block 407 and squeeze the second spring 405, driving the clamping rod 408 to cancel the clamping connection with the first fixed shaft 57 slot. The user pushes the driving plate 403 to slide on the rotating shaft 402. At this time, the driving plate 403 is separated from the first fixed shaft 57. The controller makes the motor 202 drive the rotating plate 203 to rotate, driving the second fixed shaft 204 to rotate until it rotates to the switching position. Then, the rotating plate 203 is rotated and pushed to reset, so that the second fixed shaft 204 is inserted into the driving plate 40 3. At this time, the controller makes the electromagnet 406 no longer attract the magnet block 407, and resets it through the second spring 405, driving the clamping rod 408 to clamp with the clamping slot of the second fixed shaft 204. During welding, the rotation of the second fixed shaft 204 drives the driving plate 403 to move, pushing the rotating shaft 402, the support frame 401 and the welding gun 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, which can clean impurities or particles on the moving path while making the welding gun 3 swing back and forth, further improving the welding effect and the practicality of the device, and enabling rapid conversion to facilitate adaptation to different welding modes.
