Description

Technical Field

[0001] This utility model relates to the field of welding equipment, specifically a metal frame processing anti-deviation welding device. Background Technology

[0002] In metal frame fabrication, welding is a common connection method. Its main purpose is to permanently combine two or more metal parts to meet requirements such as structural strength and sealing. Compared with other connection methods (such as bolting and riveting), welding can achieve atomic bonding, thereby obtaining higher connection strength and better overall integrity. In automated production, using welding machines for automatic welding can significantly improve production efficiency, ensure the stability of welding quality, and reduce labor costs.

[0003] When manually welding metal frames, operators must first select appropriate welding methods (such as manual arc welding, gas shielded welding, and argon arc welding) and welding materials (welding rods, welding wire, and shielding gas) based on the frame material (e.g., steel, aluminum, stainless steel) and structural requirements. They must also check that the welding machine is operating normally. Before welding, the area to be welded must be cleaned to remove rust, oil, moisture, and other impurities to avoid affecting weld quality. During welding, operators must wear appropriate protective equipment (such as welding masks, gloves, and protective clothing), adjust welding current, voltage, and welding speed parameters, hold the welding torch or welding rod at a suitable angle, ignite the arc from the starting point, maintain a stable arc length and welding posture, and then proceed with the welding.

[0004] The fumes generated during welding (usually referring to welding fumes or harmful gases) permeate the air in the workshop. Welding fumes contain harmful substances such as metal oxides (such as iron oxide, manganese oxide, hydrogen fluoride, etc.), silicon dust, nitrogen oxides, and ozone. Long-term inhalation may cause respiratory diseases such as welder's pneumoconiosis, chronic bronchitis, and emphysema. Utility Model Content

[0005] The purpose of this invention is to provide a metal frame processing anti-offset welding device to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, a metal frame processing anti-deviation welding device is provided, comprising a welding frame, a reciprocating screw movably mounted inside the welding frame, guide plates provided on both sides of the reciprocating screw, a transmission seat movably mounted inside the welding frame, a welding gun inserted and fixed inside the transmission seat, a negative pressure hopper mounted on the outer side of the end of the welding gun, the negative pressure hopper including a fixed plate mounted on the outer side of the end of the welding gun, a smoke tray covering the outer side of the fixed plate, a negative pressure pipe fixedly mounted at the end of the smoke tray, the negative pressure pipe being connected to an external negative pressure pump, and a mesh tray covering the surface of the smoke tray.

[0007] Preferably, a transmission seat is installed inside the transmission seat, and guide holes are provided on both sides of the transmission seat. Guide plates are inserted inside the two sets of guide holes. The guide plates are fixedly connected inside the welding frame, and an anti-deviation base is fixedly installed at the bottom of the welding frame.

[0008] Preferably, the negative pressure hopper includes a smoking tray, a mesh tray, a positioning seat, a positioning groove, a negative pressure pipe, a fixing plate, a docking groove, and docking blocks. The smoking tray is frustum-shaped, and two sets of docking blocks are fixedly installed on the inner circumference of the smoking tray.

[0009] Preferably, the fixed plate has two sets of mating grooves on its inner circumference wall, the mating block and the mating groove are matched in size, the bottom of the mating groove is provided with a screw hole, the mating block is provided with a through hole, the bolt passes through the through hole and is screwed into the inside of the screw hole, and the cross-section of the mating block and the mating groove is set in a dovetail shape.

[0010] Preferably, the mesh tray has multiple sets of filter holes evenly distributed on it, and five sets of positioning seats are evenly distributed on the outer circumference of the mesh tray. Five sets of positioning grooves are evenly distributed on the outer circumference of the top of the smoking tray. The size of the positioning grooves is adapted to the size of the positioning seats, and the positioning seats are engaged inside the positioning grooves.

[0011] Preferably, the bottom of the welding frame is fixedly supported by an anti-offset base. The anti-offset base includes a chassis, a support block, a base, casters, a support plate, a rubber pad, a connecting plate, studs, and nuts. The bottom sides of the chassis are fixedly connected to the base by the support block, and two sets of casters are installed on both sides of the bottom of the base.

[0012] Preferably, four sets of studs are evenly inserted on the chassis, and the bottom of each set of studs is fixed to the upper surface of the support plate. The studs are inserted on the chassis and are limited by two sets of nuts. The four sets of studs are reinforced by connecting discs, and a rubber pad is glued and fixed to the bottom of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a welding gun to perform top-down welding on a metal frame; the welding path is continuous and smooth, which can reduce the number of arc initiation and termination, and reduce the probability of welding defects; the molten pool metal is naturally filled into the weld by gravity, which helps to form a full and uniform weld shape and improves the welding quality; the welding operation has good continuity, which can avoid the accumulation of positioning errors when welding in sections, and ensure the accuracy of weld position and the consistency of overall welding.

[0015] 2. In this utility model, the smoke generated by the welding gun is absorbed by the negative pressure inside the smoke extraction tray through the negative pressure tube, preventing the smoke from filling the welding workshop. The smoke extraction tray is wider at the front and narrower at the back, and the wider front end can expand the smoke capture range, forming a larger negative pressure adsorption area near the welding gun, effectively covering the diffusion range of the smoke generated during welding; reducing the escape of smoke in the workshop; and preventing workers from developing respiratory diseases such as welder's pneumoconiosis, chronic bronchitis, and emphysema due to long-term inhalation.

[0016] 3. When the welding gun on the welding frame is used for welding, the support plate can be moved downwards, causing the rubber pad at the bottom of the support plate to press against the workshop floor, thereby increasing the friction between the device and the ground. Two sets of studs are screwed onto the studs to lock the height of the support plate, ensuring the stability of the welding frame when stationary and the stability of the welding gun during welding. This prevents weld seam displacement during the welding process of the metal frame and improves weld quality. Attached Figure Description

[0023] Please see Figure 1-5This utility model provides a metal frame processing anti-deviation welding device, including a welding frame 1, a reciprocating screw 2 movably installed inside the welding frame 1, guide plates 3 provided on both sides of the reciprocating screw 2, a transmission seat 4 movably installed inside the welding frame 1, a welding gun 5 inserted and fixed inside the transmission seat 4, a negative pressure bucket 6 installed on the outer side of the end of the welding gun 5, the negative pressure bucket 6 includes a fixed plate 64 installed on the outer side of the end of the welding gun 5, a smoke tray 61 covering the outer side of the fixed plate 64, a negative pressure pipe 63 fixedly installed at the end of the smoke tray 61, the negative pressure pipe 63 being connected to an external negative pressure pump, and a mesh tray 62 covering the surface of the smoke tray 61.

[0024] Working Principle: In actual use, the device is placed at the location of the metal frame to be welded. A servo motor (not shown in the diagram) can be installed on the top of the welding frame 1. The servo motor drives the reciprocating screw 2 to rotate, which in turn drives the transmission seat 4 mounted on it to move from top to bottom. Through the welding gun 5, the metal frame is welded. The welding path is continuous and smooth, reducing the number of arc initiation and termination, and lowering the probability of welding defects. Gravity allows the molten metal to naturally fill the weld, which helps to form a full and uniform weld shape, improving welding quality. The welding operation has good continuity, avoiding the accumulation of positioning errors during segmented welding, ensuring the accuracy of the weld position and the consistency of the overall welding. It is suitable for welding large areas or long welds, reducing the time for pauses and adjustments during the welding process, and improving welding efficiency. The top-down welding direction makes it easy for operators to observe the state of the molten pool and the weld formation, and adjust welding parameters in a timely manner to ensure a stable and controllable welding process.

[0025] The smoke generated by the welding torch 5 is absorbed by the negative pressure created inside the fume extraction tray 61 through the negative pressure pipe 63, preventing the smoke from filling the welding workshop. The fume extraction tray 61 is truncated cone-shaped, wider at the front and narrower at the back. This design expands the smoke capture range, creating a larger negative pressure absorption area near the welding torch 5, effectively covering the spread of smoke generated during welding. The narrower rear end facilitates connection to the negative pressure pipe 63, reducing resistance caused by changes in the cross-sectional area of ​​the airflow channel and improving smoke extraction efficiency. The truncated cone curved structure... The system guides the smoke to flow smoothly along the disc surface to the negative pressure pipe 63, reducing suction loss caused by airflow turbulence and making adsorption more concentrated and efficient. Its front-wide, back-narrow shape fits the layout of the welding operation space, and the large surface area of ​​the frustum-shaped structure increases the contact time between the smoke and the disc surface, aiding in the adsorption of fine particles and improving the overall smoke purification effect. It conforms to aerodynamic principles, forming a stable airflow field under negative pressure, enhancing the ability to capture smoke diffusing in different directions and reducing smoke escape from the workshop. This prevents long-term inhalation by workers from potentially causing respiratory diseases such as welder's pneumoconiosis, chronic bronchitis, and emphysema.

[0026] The bottom of the welding frame 1 is supported by an anti-deviation base 7, which has four sets of casters 74 for easy movement. When the welding gun 5 on the welding frame 1 is performing welding work, the support plate 75 can be moved downwards, so that the rubber pad 76 at the bottom of the support plate 75 presses against the workshop floor to increase the friction between the device and the floor. Two sets of studs 78 are screwed onto the studs 78 to lock the height of the support plate 75, ensuring the stability of the welding frame 1 when stationary, and ensuring the stability of the welding gun 5 when welding. This prevents weld seam deviation during the welding of the metal frame and improves weld quality.

[0027] In a preferred embodiment, a transmission base 4 is inserted inside the transmission base 4. Guide holes are provided on both sides of the transmission base 4. Guide plates 3 are inserted inside the two sets of guide holes. The guide plates 3 are fixedly connected inside the welding frame 1.

The smoking tray 61 is frustum-shaped, and two sets of docking blocks 66 are fixedly arranged on the inner circumference of the smoking tray 61.

[0029] As a preferred embodiment, two sets of mating grooves 65 are provided on the inner circumference of the fixed plate 64. The mating block 66 and the mating groove 65 are matched in size. The bottom of the mating groove 65 is provided with a screw hole, and the mating block 66 is provided with a through hole. The bolt passes through the through hole and is screwed into the inside of the screw hole. The cross-section of the mating block 66 and the mating groove 65 is set in a dovetail shape.
