However, in the aforementioned patent, the steel may shake during the height adjustment process, which may affect the joint accuracy between the steel pieces. Therefore, a metal welding device that can fix the steel during height adjustment is designed to facilitate height adjustment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a metal welding device with easily adjustable height, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal welding device with adjustable height, comprising a base frame, an equipment frame fixedly mounted on top of the base frame, a motor fixedly mounted on top of the equipment frame, and a clamping device; wherein the clamping device comprises a lead screw, a welding plate, a fixing plate, a U-shaped plate, a connecting rod, and a connecting plate, the lead screw being fixedly mounted on the output end of the motor, the welding plate being slidably mounted on the circumferential surface of the lead screw, the fixing plate being slidably mounted above the welding plate, and the U-shaped plate slidingly penetrating the inner and outer walls of the fixing plate. A sliding groove is formed on the surface of the equipment frame, the connecting rod is slidably mounted inside the sliding groove, and the connecting plate is fixedly mounted on the surface of the connecting rod. Simultaneously, when fixing steel, if the steel is too long, it will compress the U-shaped plate, causing it to move closer to the fixing plate. The movement of the U-shaped plate compresses the spring, causing it to contract. When welding is finished, the steel is removed, the spring returns to its original position, and the U-shaped plate returns to its original position, thus achieving the clamping and fixing of steel of different lengths.

[0007] According to the above technical solution, the end of the lead screw away from the motor is rotatably connected to the top of the base frame, a spring is provided between the fixed plate and the U-shaped plate, and the end of the connecting plate away from the connecting rod is fixedly connected to the fixed plate. When the steel is too long, it will squeeze the U-shaped plate to move closer to the fixed plate, and the movement of the U-shaped plate will compress the spring.

[0008] According to the above technical solution, the cleaning device includes a movable plate, an L-shaped plate, a receiving plate, a protrusion, and a convex plate. The surface of the welding plate is provided with a movable groove. The movable plate is slidably installed inside the movable groove. The L-shaped plate is fixedly installed below the welding plate. The receiving plate is fixedly installed at the end of the L-shaped plate away from the movable plate. The protrusion is fixedly installed above the L-shaped plate. The convex plate is fixedly installed below the movable plate. The U-shaped plate moves to contact and push the movable plate to move away from the U-shaped plate. The movable plate moves to contact and squeeze the telescopic end of the telescopic spring rod to retract. The movable plate moves to open the cleaning groove, which can effectively remove oxides and other impurities from the welding surface.

[0009] According to the above technical solution, a cleaning groove is provided on the surface of the welding plate, the end of the protrusion away from the L-shaped plate is set as convex surface one, and the end of the protrusion away from the moving plate is set as convex surface two. The moving plate moves and drives the protrusion to move. The moving protrusion contacts and squeezes the protrusion to generate vibration.

[0010] According to the above technical solution, a telescopic spring rod is fixedly installed at the end of the L-shaped plate away from the protrusion, and a movable plate is fixedly connected to the free end of the telescopic spring rod. The movable plate moves to contact and squeeze the telescopic end of the telescopic spring rod to retract.

[0011] According to the above technical solution, the lubrication device includes an oil tank, a fixed block, an oil storage tank, an oil inlet tank, a moving block, an oil spray pipe, and a sponge block. The oil tank is slidably mounted on the surface of a welding plate. A fixing groove is formed on the surface of the welding plate. The fixed block is slidably mounted inside the fixing groove. The oil storage tank is fixedly mounted through the inner and outer walls of the oil tank. The oil inlet tank is slidably mounted inside the oil storage tank. The moving block is fixedly mounted below the oil inlet tank. The oil spray pipe is fixedly mounted through the inner and outer walls of the oil storage tank. The sponge block is fixedly mounted on the surface of a connecting plate. The moving block moves upward, causing the oil inlet tank to move upward. The upward movement of the oil inlet tank closes the oil inlet groove. At the same time, the upward movement of the oil inlet tank squeezes the oil inside the oil storage tank and sprays it onto the sponge block through the oil spray pipe.

[0012] According to the above technical solution, the oil tank is fixedly connected to the fixed block, and an oil inlet groove is provided on the surface of the oil inlet barrel. The upward movement of the moving block drives the oil inlet barrel to move upward, and the upward movement of the oil inlet barrel closes the oil inlet groove.

[0013] According to the above technical solution, the end of the moving block away from the oil tank is set as a beveled surface. The sponge block contacts the connecting rod, and the receiving plate contacts and squeezes the beveled surface of the moving block to move upward. When the connecting rod moves, it contacts and squeezes the sponge block to produce deformation, so that the oil inside the sponge block contacts the surface of the connecting rod.

[0014] This invention provides a metal welding device with easily adjustable height. It offers the following advantages:

[0015] (1) This height-adjustable metal welding device, through the coordinated operation of the lead screw, welding plate, fixing plate, U-shaped plate, connecting rod, and connecting plate, realizes the height adjustment of the welding plate, which can move the welding table freely up or down. The height adjustment facilitates the precise docking of the welding parts, thereby reducing weld defects and improving the integrity of the welding. The appropriate height can help the welder better control the shape and size of the molten pool and ensure the accuracy of the weld. At the same time, when the connecting rod is in the middle of the sliding groove, the steel is not fixed. When the connecting rod moves up or down, it drives the fixing plate to move closer to the steel and fix it. This realizes that the steel can be fixed when adjusting the height, preventing the steel from shaking during adjustment, causing the steel to fall and damaging the equipment, thereby increasing the subsequent maintenance cost. At the same time, when fixing the steel, if the steel cannot be fixed and clamped according to its length, the self-adaptive system can ensure that the steel maintains the correct position and length during the welding process. The self-adaptive fixing system can be adjusted according to different steel lengths and welding requirements to adapt to various different steels.

[0016] (2) The height-adjustable metal welding device operates by the cooperation of the moving plate, L-shaped plate, receiving plate, protrusion, convex plate and telescopic spring rod. The moving plate moves to open the cleaning tank, which can effectively remove oxides and other impurities from the welding surface, thereby ensuring the cleanliness of the welding material, reducing weld defects and improving welding quality. The welding slag and impurities generated by welding are discharged through the cleaning tank, which can reduce the corrosion and wear of equipment and tools, thereby extending their service life. At the same time, vibration is generated, which makes it easier for the welding slag and impurities in the welding tank to fall off the welding surface, ensuring the cleanliness of the welding part and thus improving the welding quality. Through vibration, impurities in the cleaning tank will not be deposited, which helps to maintain the cleanliness of the welding environment.

[0017] (3) The height-adjustable metal welding device works in coordination with the oil tank, fixed block, oil storage tank, oil inlet tank, moving block, oil spray pipe and sponge block. Using sponge block for lubrication can avoid excessive overflow of lubricant, thereby reducing subsequent cleaning work. Regularly spraying lubricant on sponge block can keep the equipment in good condition and facilitate inspection during maintenance. At the same time, when the connecting rod moves, it contacts and squeezes the sponge block to deform, so that the oil inside the sponge block contacts the surface of the connecting rod for lubrication. By reducing friction, the equipment will move more smoothly and improve operating efficiency. The film formed by the lubricating oil can protect the contact surface during movement, reduce wear caused by friction, and thus extend the service life of the equipment. Attached Figure Description

[0027] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 One embodiment of the present invention is a metal welding device with adjustable height, comprising a base frame 1, an equipment frame 2 fixedly mounted on the base frame 1, a motor 3 fixedly mounted on the equipment frame 2, and a clamping device. The clamping device includes a lead screw 4, a welding plate 5, a fixing plate 6, a U-shaped plate 7, a connecting rod 9, and a connecting plate 10. The lead screw 4 is fixedly mounted on the output end of the motor 3, the welding plate 5 is slidably mounted on the circumferential surface of the lead screw 4, the fixing plate 6 is slidably mounted above the welding plate 5, and the U-shaped plate 7 slides through the inner and outer walls of the fixing plate 6. A sliding groove 201 is formed on the surface of the equipment frame 1, the connecting rod 9 is slidably mounted inside the sliding groove 201, and the connecting plate 10 is fixedly mounted on the surface of the connecting rod 9. When the steel is removed, the spring 8 resets and drives the U-shaped plate 7 to reset, thus achieving the fixed clamping of steel of different lengths. Through self-adaptation, it can ensure that the steel maintains the correct position and length during welding, reducing poor jointing caused by material deformation and improving welding accuracy. The self-adaptive fixing system can be adjusted according to different steel lengths and welding requirements, adapting to various types of steel.

[0029] The end of the lead screw 4 away from the motor is rotatably connected to the top of the base frame 1. A spring 8 is provided between the fixed plate 6 and the U-shaped plate 7. The end of the connecting plate 10 away from the connecting rod 9 is fixedly connected to the fixed plate 6. When the steel is too long, it will squeeze the U-shaped plate 7 to move closer to the fixed plate 6. The movement of the U-shaped plate 7 squeezes the spring 8 to contract.

[0030] In this embodiment, when the height of the steel needs to be adjusted, motor 3 is started. The output end of motor 3 rotates, driving the lead screw 4 to rotate. The rotation of the lead screw 4 drives the welding plate 5 to move. Simultaneously, the upward movement of the welding plate 5 drives the moving plate 10 to move upward, and the upward movement of the moving plate 10 drives the connecting rod 9 to move upward, thus realizing the height adjustment of the welding plate 5. The welding table can be moved freely up or down. Adjusting the height facilitates precise docking of the welded parts, thereby reducing weld defects and improving weld integrity. A suitable height helps the welder better control the shape and size of the molten pool, ensuring the accuracy of the weld. When the steel is placed above the welding plate 5, and the connecting rod 9 is in the middle part of the sliding groove 201, the steel is not fixed. When the connecting rod 9 moves up or down, it drives the connecting rod 9 to move upward. The fixing plate 6 moves closer to the steel and is fixed in place, thus securing the steel during height adjustment to prevent it from wobbling and falling, which could damage the equipment and increase subsequent maintenance costs. Simultaneously, when fixing the steel, if it is too long, it will compress the U-shaped plate 7, causing it to move closer to the fixing plate 6. The movement of the U-shaped plate 7 compresses the spring 8, causing it to contract. When welding is finished, the steel is removed, the spring 8 resets, and the U-shaped plate 7 resets as well. This allows for the fixing and clamping of steel of different lengths. Through self-adaptation, it ensures that the steel maintains the correct position and length during welding, reducing poor jointing caused by material deformation and improving welding accuracy. The adaptive fixing system can adjust according to different steel lengths and welding requirements, adapting to various types of steel.

[0031] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a cleaning device and a lubrication device; the cleaning device includes a movable plate 111, an L-shaped plate 112, a receiving plate 114, a protrusion 115, and a protruding plate 116. A movable groove 117 is opened on the surface of the welding plate 5. The movable plate 111 is slidably installed inside the movable groove 117. The L-shaped plate 112 is fixedly installed below the welding plate 5. The receiving plate 114 is fixedly installed at the end of the L-shaped plate 112 away from the movable plate 111. The protrusion 115 is fixedly installed above the L-shaped plate 112. The protruding plate 116 is fixedly installed below the movable plate 111. The movable plate 111 moves to open the cleaning groove 118, which can effectively remove oxides and other impurities from the welding surface, thereby ensuring the cleanliness of the welding material, reducing weld defects, and improving welding quality. By removing welding slag and impurities generated during welding through the cleaning groove, the corrosion and wear of equipment and tools can be reduced, thereby extending their service life.

[0032] The surface of the welding plate 5 is provided with a cleaning groove 118. The end of the protrusion 115 away from the L-shaped plate 112 is set as the first convex surface, and the end of the protrusion 116 away from the moving plate 111 is set as the second convex surface. The moving plate 111 moves and drives the protrusion 116 to move. The moving protrusion 116 contacts and squeezes the protrusion 115 to generate vibration.

[0033] A telescopic spring rod 113 is fixedly installed at the end of the L-shaped plate 112 away from the protrusion 115. The free end of the telescopic spring rod 113 is fixedly connected to a movable plate 111. The movable plate 111 moves to contact and squeeze the telescopic end of the telescopic spring rod 113 to retract.

[0034] The lubrication device includes an oil tank 121, a fixing block 122, an oil storage tank 123, an oil inlet tank 124, a moving block 125, an oil spray pipe 126, and a sponge block 127. The oil tank 121 is slidably mounted on the surface of the welding plate 5. A fixing groove 128 is provided on the surface of the welding plate 5. The fixing block 122 is slidably mounted inside the fixing groove 128. The oil storage tank 123 is fixedly mounted through the inner and outer walls of the oil tank 121. The oil inlet tank 124 is slidably mounted inside the oil storage tank 123. The moving block 125 is fixedly mounted below the oil inlet tank 124. The oil spray pipe 126 is fixedly mounted through the inner and outer walls of the oil storage tank 123. The sponge block 127 is fixedly mounted on the surface of the connecting plate 10. The oil is sprayed onto the sponge block 127 through the oil spray pipe 126. Using the sponge block for lubrication can prevent excessive overflow of lubricant, thereby reducing subsequent cleaning work. Regularly spraying the sponge block with lubricant can maintain the good condition of the equipment and facilitate inspection during maintenance.

[0035] The oil tank 121 is fixedly connected to the fixed block 122. The surface of the oil inlet 124 is provided with an oil inlet groove 129. The moving block 125 moves upward, causing the oil inlet 124 to move upward. The upward movement of the oil inlet 124 closes the oil inlet groove 129.

[0036] The end of the moving block 125 away from the oil tank 121 is set as a bevel. The sponge block 127 contacts the connecting rod 9. The receiving plate 114 contacts and squeezes the bevel of the moving block 125 to move upward. When the connecting rod 9 moves, it contacts and squeezes the sponge block 127 to produce deformation, so that the oil inside the sponge block 127 contacts the surface of the connecting rod 9.

[0037] When the U-shaped plate 7 moves and contacts the moving plate 111, pushing it away from the U-shaped plate 7, the moving plate 111 contacts and compresses the telescopic end of the telescopic spring rod 113, causing it to retract. The moving plate 111 opens the cleaning groove 118, effectively removing oxides and other impurities from the welding surface, thus ensuring the cleanliness of the welding materials, reducing weld defects, and improving welding quality. The cleaning groove removes welding slag and impurities, reducing corrosion and wear on equipment and tools, thereby extending their service life. When the moving plate 111 moves, it drives the convex plate 116 to move. The convex plate 116 contacts and compresses the protrusion 115, generating vibration. This vibration makes it easier for welding slag and impurities in the welding groove to fall off the welding surface, ensuring the cleanliness of the welding area and improving welding quality. Through vibration, impurities in the cleaning groove do not accumulate, helping to maintain a clean welding environment.

[0038] When lubrication of the connecting rod 9 is required, the oil tank 121 is pulled. The oil tank 121 moves along the fixed groove 128 via the fixed block 122. The movement of the oil tank 121 drives the moving block 125 to move. The inclined surface of the moving block 125 moves to contact and press the receiving plate 114, causing the moving block 125 to move upward. The upward movement of the moving block 125 drives the oil inlet tank 124 to move upward. The upward movement of the oil inlet tank 124 closes the oil inlet groove 129. At the same time, the upward movement of the oil inlet tank 124 compresses the oil inside the oil storage tank 123 and sprays it onto the sponge block 127 through the oil spray pipe 126. Using a sponge block for lubrication can prevent excessive lubricant overflow, thereby reducing subsequent cleaning work. Regularly spraying the sponge block with lubricant can keep the equipment in good condition and facilitate inspection during maintenance. When the connecting rod 9 moves, it contacts and squeezes the sponge block 127, causing deformation. This allows the oil inside the sponge block 127 to contact the surface of the connecting rod 9 for lubrication. By reducing friction, the equipment moves more smoothly, improving operating efficiency. The film formed by the lubricating oil can protect the contact surfaces during movement, reducing wear caused by friction and thus extending the service life of the equipment.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
