Description

Technical Field

[0001] This invention relates to the field of welding support device technology, and in particular to a support device for welding high-strength aluminum. Background Technology

[0002] High-strength aluminum is an aluminum alloy material with high strength and rigidity. It is often used in applications that require high strength and lightweight. The main reason for welding high-strength aluminum is to connect different aluminum alloy parts together to form an integral structure or component.

[0003] Chinese Patent (CN112719751B) discloses a welding support device. This patent allows two welding components to be inserted from both ends of the device, passing through the corresponding square frame and bottom shell, respectively, and the two welding components to come into contact. The base motor is started, which drives a bidirectional threaded rod to rotate. The bidirectional threaded rod is threadedly connected to the sliding feet. At this time, the sliding feet at both ends move towards the middle, thereby closing the support rods at both ends and raising the H-frame. The purpose of raising the H-frame to support the welding components is to ensure that the welding machine can be stably placed on the device before being fixed by the device, making it convenient for the operator to position and fix the welding components.

[0004] When using the existing welding support device, one side of the high-strength aluminum needs to be welded first. After the welding is completed and the aluminum is allowed to cool naturally, it needs to be manually flipped over to weld the other side of the high-strength aluminum. However, when the operator flips the aluminum over manually, the welding positioning after flipping may be inaccurate, which may lead to the displacement or misalignment of the welded parts, affecting the quality and precision of the weld. Summary of the Invention

[0005] To address the technical problems mentioned in the background section, this invention provides a support device for welding high-strength aluminum. Its advantages are: it can automatically weld high-strength aluminum on the other side through the welding components, avoiding inaccurate welding positioning after manual flipping, and preventing the offset or misalignment of the welded components, which would affect the quality and precision of the weld.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A high-strength aluminum welded support device includes a support platform, a connecting plate on the top of the support platform, and a flipping component on one side of the connecting plate. The flipping assembly includes a first slide groove, which is fixedly connected to a connecting plate. A second slide groove is fixedly connected to the lower end of the first slide groove. A slider is provided on one side of the connecting plate. Both the first and second slide grooves are slidably connected to the slider. A transmission gear is provided on one side of the slider. A second rack plate is fixedly connected to one end of the connecting plate. The second rack plate is located on one side of the second slide groove and meshes with the transmission gear. A telescopic rod is fixedly connected to one side of the transmission gear. A slide rail is provided inside the telescopic rod. A slide rod is fixedly connected inside the slide rail. A connecting box is fixedly connected to the wall. The connecting box has a sliding groove inside, which is slidably connected to the sliding rod. A fixed plate is fixedly connected to the end of the support platform away from the connecting plate. A placement frame is connected to the telescopic rod and the fixed plate through a rotating shaft. A rotating block is rotatably connected to one end of the telescopic rod. The placement frame is located on one side of the rotating block. Plates are fixedly connected to both ends of the connecting plate. Irregular slide rails are fixedly connected to the opposite ends of the two plates. The two irregular slide rails are staggered. A cylinder is provided at one end of one of the plates. The output end of the cylinder is fixedly connected to the rotating block.

[0007] Through the above technical solutions, the flipping component can automatically weld the high-strength aluminum on the other side through the welding component, avoiding inaccurate welding positioning after flipping when flipping manually, and preventing the offset or misalignment of the welded parts, which would affect the quality and accuracy of the weld.

[0008] The invention is further configured such that the inner side of the placement frame is provided with two sets of clamping plates, each set of clamping plates consists of two plates, and two electric push rods are fixedly connected to the inner side of the placement frame. One set of clamping plates is fixedly connected to the output end of the electric push rod, and the other set of clamping plates is fixedly connected to the placement frame through the rod body. A welding assembly is provided at the end of the support platform away from the fixed plate.

[0009] Through the above technical solutions, the clamping plate can ensure the stable positioning of the welded parts.

[0010] The invention is further configured such that the welding assembly includes a support cylinder, which is fixedly connected to a support platform. A support frame is provided on one side of the support cylinder, and a sliding groove is provided at the bottom of the support frame. A telescopic plate is slidably connected inside the sliding groove. A connecting cylinder is provided on one side of the telescopic plate, and a first rack plate is slidably connected inside the connecting cylinder. A motor is provided on one side of the connecting cylinder, and a drive gear is connected to the output end of the motor through a rotating shaft. A welding torch is provided below the first rack plate.

[0011] Through the above technical solutions, the welding assembly can weld high-strength aluminum.

[0012] The invention is further configured such that the drive gear meshes with the first rack plate, the welding torch is located above the placement frame, and a cooling assembly is provided below the placement frame.

[0013] The present invention is further configured such that the cooling assembly includes a suction hood, a placement block is fixedly connected to one end of the support platform, the placement block is located on one side of the plate, the suction hood is connected to the placement block, an air inlet pipe is connected to one end of the suction hood, an air pump is provided at the bottom of the support platform, one end of the air inlet pipe is connected to the input end of the air pump, a heat sink is provided at one end of the air inlet pipe, an air delivery pipe is connected to the output end of the air pump, and a plurality of nozzles are connected to one end of the air delivery pipe.

[0014] Through the above technical solutions, the cooling components can purify the flue gas while gradually reducing the temperature of the welding area.

[0015] The invention is further configured such that a cooling box is provided on the top of the support platform, and the gas supply pipe is located inside the cooling box.

[0016] The present invention is further configured such that the heat sink is provided with a plurality of semiconductor cooling chips inside, and the end of the air inlet pipe away from the heat sink is connected to a housing.

[0017] Through the above technical solutions, semiconductor cooling chips can further improve the heat dissipation effect of heat sinks, and transfer and dissipate heat more effectively.

[0018] The invention is further configured such that the interior of the housing is provided with multiple filter screens, and the air supply pipe is located directly below the placement frame.

[0019] Through the above technical solutions, multiple filters can reduce the risk of workers inhaling harmful substances, protect their respiratory system and health, and also reduce environmental pollution.

[0020] The beneficial effects of this invention are as follows: This invention, through the setting of a flipping component, enables the flipping of high-strength aluminum during welding and allows for cooling of the welded side. Specifically, after one side is welded, a cylinder pushes a rotating block to move, which in turn moves the placement frame downwards, causing the second rack plate to contact the transmission gear. The second rack plate drives the transmission gear to rotate, which in turn causes the placement frame to rotate 180°. The cooling component cools the welded side. After cooling, the cylinder drives the placement frame to move back, automatically welding the other side of the high-strength aluminum through the welding component. This avoids inaccurate welding positioning after flipping, which can occur when manually flipping the aluminum, and prevents the welding components from shifting or misaligning, thus affecting the quality and precision of the weld.

[0021] This invention ensures stable positioning of the welding components through the clamping plate. Specifically, two pieces of high-strength aluminum are placed between two fixed plates, and then two electric push rods are activated to fix the high-strength aluminum, providing a stable welding platform and preventing displacement or misalignment during welding. Through the welding assembly, high-strength aluminum can be welded. Specifically, during welding, the telescopic plate drives the welding torch below the connecting cylinder to move horizontally, and the motor drives the drive gear to rotate, which in turn moves the first rack plate up and down, thereby enabling the welding torch to move vertically, allowing for more flexible welding of high-strength aluminum.

[0022] This invention, through the design of a cooling component, can purify the fumes while gradually reducing the temperature of the welding area. Specifically, when the welding torch is welding high-strength aluminum, the fumes generated during welding are transported through the air intake pipe on the air pump to the inside of the air delivery pipe via the suction hood. When passing through the heat sink at one end of the air intake pipe, the heat sink increases its surface area to improve heat dissipation efficiency, transferring heat to the surrounding air. At the same time, the semiconductor cooling chip further enhances the heat dissipation effect of the heat sink, transferring and dissipating heat more effectively, thereby reducing the temperature of the fumes passing through the heat sink. The cooled fumes are then transported to the air delivery pipe by the air pump and sprayed out by multiple nozzles to cool the high-strength aluminum after welding. This helps to alleviate the thermal stress of the high-strength aluminum, reducing its adverse effects on the welded parts and weld seams, improving welding quality, and also accelerating the cooling rate of the high-strength aluminum welded parts, shortening the welding cycle.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] The embodiments of this patent are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0027] Reference Figures 1-8 A high-strength aluminum welding support device includes a support platform 1, a connecting plate 10 on the top of the support platform 1, and a flipping component on one side of the connecting plate 10. The flipping assembly includes a first slide groove 17, which is fixedly connected to a connecting plate 10. A second slide groove 18 is fixedly connected to the lower end of the first slide groove 17. A slider 25 is provided on one side of the connecting plate 10. Both the first slide groove 17 and the second slide groove 18 are slidably connected to the slider 25. A transmission gear 22 is provided on one side of the slider 25. A second rack plate 24 is fixedly connected to one end of the connecting plate 10. The second rack plate 24 is located on one side of the second slide groove 18 and meshes with the transmission gear 22. A telescopic rod 26 is fixedly connected to one side of the transmission gear 22. A slide rail is provided inside the telescopic rod 26, and a slide rod 21 is fixedly connected inside the slide rail. A connecting box 20 is fixedly connected to the outer wall of the support platform 1. A sliding groove is provided inside the connecting box 20. The sliding groove is slidably connected to the sliding rod 21. A fixed plate 13 is fixedly connected to the end of the support platform 1 away from the connecting plate 10. A placement frame 14 is connected to the telescopic rod 26 and the fixed plate 13 through a rotating shaft. A rotating block 27 is rotatably connected to one end of the telescopic rod 26. The placement frame 14 is located on one side of the rotating block 27. Plates 12 are fixedly connected to both ends of the connecting plate 10. Irregular slide rails 23 are fixedly connected to the opposite ends of the two plates 12. The two irregular slide rails 23 are staggered. A cylinder 11 is provided at one end of one of the plates 12. The output end of the cylinder 11 is fixedly connected to the rotating block 27.

[0028] By setting up the flipping component, the welding of high-strength aluminum can be performed by flipping the aluminum and cooling the welded side. Specifically, after one side is welded, the cylinder 11 pushes the rotating block 27 to move, which in turn moves the placement frame 14 downward, so that the second rack plate 24 contacts the transmission gear 22. The second rack plate 24 drives the transmission gear 22 to rotate, which in turn drives the placement frame 14 to rotate 180°. The cooling component cools the welded side. After cooling, the cylinder 11 drives the placement frame 14 to move back, and the welding component automatically welds the other side of the high-strength aluminum. This avoids inaccurate welding positioning after flipping when flipping manually, and prevents the welding parts from shifting or misaligning, which would affect the quality and accuracy of the weld.

[0029] Reference Figures 4-5 The inner side of the placement frame 14 is provided with two sets of clamping plates 16, and the number of clamping plates 16 in each set is set to two. Two electric push rods 15 are fixedly connected to the inner side of the placement frame 14. One set of clamping plates 16 is fixedly connected to the output end of the electric push rod 15, and the other set of clamping plates 16 is fixedly connected to the placement frame 14 through the rod body. The end of the support platform 1 away from the fixed plate 13 is provided with a welding assembly.

[0030] By setting the clamping plate 16, the stable positioning of the welding parts can be ensured. Specifically, two pieces of high-strength aluminum are placed between two fixing plates 13, and then two electric push rods 15 are activated to fix the high-strength aluminum, providing a stable welding platform and preventing it from shifting or misaligning during the welding process.

[0031] Reference Figures 1-3 The welding assembly includes a support cylinder 2, which is fixedly connected to a support platform 1. A support frame 3 is provided on one side of the support cylinder 2. A sliding groove is provided at the bottom of the support frame 3. A telescopic plate 4 is slidably connected inside the sliding groove. A connecting cylinder 5 is provided on one side of the telescopic plate 4. A first rack plate 7 is slidably connected inside the connecting cylinder 5. A motor 9 is provided on one side of the connecting cylinder 5. The output end of the motor 9 is connected to a drive gear 6 through a rotating shaft. A welding torch 8 is provided below the first rack plate 7.

[0032] By setting up the welding components, high-strength aluminum can be welded. Specifically, during welding, the telescopic plate 4 drives the welding torch 8 below the connecting cylinder 5 to move horizontally, and the motor 9 drives the drive gear 6 to rotate, which in turn drives the first rack plate 7 to move up and down, thereby enabling the welding torch 8 to move vertically, which allows for more flexible welding of high-strength aluminum.

[0033] Reference Figures 7-8 The drive gear 6 meshes with the first rack plate 7. The welding torch 8 is located above the placement frame 14. A cooling assembly is provided below the placement frame 14. The cooling assembly includes a suction hood 29. One end of the support platform 1 is fixedly connected to a placement block 28, which is located on one side of the plate 12. The suction hood 29 is connected to the placement block 28. One end of the suction hood 29 is connected to an air inlet pipe 32. The bottom of the support platform 1 is provided with an air pump 35. One end of the air inlet pipe 32 is connected to the input end of the air pump 35. One end of the air inlet pipe 32 is provided with a heat sink 33. The output end of the air pump 35 is connected to an air delivery pipe 37. One end of the air delivery pipe 37 is connected to multiple nozzles 19.

[0034] By configuring the cooling components, the temperature of the welding area can be gradually reduced while purifying the fumes. Specifically, when the welding torch 8 welds high-strength aluminum, the fumes generated during welding are transported to the inside of the air supply pipe 37 through the air inlet pipe 32 on the air pump 35 via the suction hood 29. When passing through the heat sink 33 at one end of the air inlet pipe 32, the heat sink 33 can increase its surface area to improve heat dissipation efficiency and transfer heat to the surrounding air. At the same time, the semiconductor cooling chip 34 can further improve the heat dissipation effect of the heat sink 33, transferring and dissipating heat more effectively, thereby reducing the temperature of the fumes passing through the heat sink 33. The cooled fumes are then transported to the air supply pipe 37 by the air pump 35 and sprayed out by multiple nozzles 19 to cool the high-strength aluminum after welding. This can help alleviate the thermal stress of the high-strength aluminum, reduce its adverse effects on the welded parts and welds, improve the welding quality, and accelerate the cooling rate of the high-strength aluminum welded parts, shortening the welding cycle.

[0035] Reference Figures 7-8The top of the support platform 1 is provided with a cooling box 36, the air supply pipe 37 is located inside the cooling box 36, the heat sink 33 is provided with multiple semiconductor cooling chips 34, the end of the air inlet pipe 32 away from the heat sink 33 is connected to a housing 30, the housing 30 is provided with multiple filters 31, and the air supply pipe 37 is located directly below the placement frame 14.

[0036] The welding fumes can be purified by multiple filters 31, which can be pre-filters, HEPA filters, and activated carbon filters. First, the pre-filters remove larger particles from the fumes, then the HEPA filters remove fine particles, and finally the activated carbon filters remove organic gases and odors from the welding fumes. This reduces the risk of workers inhaling harmful substances, protects their respiratory system and health, and also reduces environmental pollution.

[0037] Working Principle: In operation, two pieces of high-strength aluminum are first placed between two fixed plates 13. Then, two electric push rods 15 are activated to secure the two pieces of high-strength aluminum. Next, the welding torch 8 is activated to weld the high-strength aluminum. During welding, the air pump 35 is activated, drawing the welding fumes into the housing 30 through the suction hood 29. The fumes are then purified through multiple filters 31 and transported to the air supply pipe 37 via the inlet pipe 32. As the fumes pass through the heat sink 33 at one end of the inlet pipe 32, the surface area of ​​the heat sink 33 increases, improving heat dissipation efficiency and transferring heat to the surrounding air. Simultaneously, the semiconductor cooling chip 34 further enhances the heat sink 33's heat dissipation efficiency. The heat dissipation effect is improved, and heat is transferred and dissipated more effectively, thereby reducing the temperature of the flue gas passing through the heat sink 33. The cooled flue gas is transported to the air supply pipe 37 by the air pump 35 and sprayed out by multiple nozzles 19. After the high-strength aluminum side is welded, the cylinder 11 pushes the rotating block 27 to move, which in turn drives the placement frame 14 to move downward. When the slider 25 on the side of the transmission gear 22 is located in the first slide groove 17, the slider 25 cannot rotate inside the first slide groove 17 because the first slide groove 17 has a limiting effect on the slider 25. When the slider 25 slides to the second slide groove 18, because the width of the second slide groove 18 is smaller than that of the first slide groove 17, the slider 25 cannot rotate inside the second slide groove 18. Located outside the second slide groove 18, and not limiting the slider 25, the second rack plate 24 contacts the transmission gear 22. The second rack plate 24 drives the transmission gear 22 to rotate, thereby driving the placement frame 14 to rotate 180°. The cylinder 11 continues to drive the placement frame 14 to move. When the slide rod 21 contacts the irregular slide rail 23 on the plate 12 at the bottom, the trajectory of the irregular slide rail 23 causes the slide rod 21 to move to the right, thereby driving the transmission gear 22 on the telescopic rod 26 to move to the right and disengage from the second rack plate 24. At this time, the welded side faces the nozzle 19. The purified fumes sprayed from the nozzle 19 cool the welded side of the high-strength aluminum. After cooling... After completion, the cylinder 11 moves the placement frame 14 upward. When it moves upward, the transmission gear 22 disengages from the second rack plate 24, and the slider 25 slides into the inner wall of the first slide groove 17, thus limiting the placement frame 14 after flipping, which facilitates the welding of the high-strength aluminum on the other side. When the cylinder 11 drives the placement frame 14 to move back, because the irregular slide rail 23 on the top plate 12 is opposite to the irregular slide rail 23 at the bottom, when the slide rod 21 contacts it, the slide rod 21 drives the telescopic rod 26 to slide to the left in the first slide groove 17, so that the transmission gear 22 returns to the track in which it can mesh with the second rack plate 24. This cycle repeats for welding, flipping, and cooling.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
