Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an automatic welding device for iron frame bed connectors. Background Technology

[0002] Connecting components of iron bunk beds, such as corner brackets, pipe joints, and support plates, are the core guarantee of the structural strength of iron bunk beds, and their welding quality directly affects the load-bearing capacity and safety of the bed.

[0003] Patent CN215546138U relates to an automatic welding device for iron frame bed connectors, belonging to the field of processing equipment technology. Its key technical features include: a worktable, two rotating shafts mounted on the worktable, two sliders threaded onto the rotating shafts, a first concave block mounted on the sliders, a rotating rod mounted on the worktable and connected to the two rotating shafts via a worm gear, a second concave block mounted on the worktable, and an automatic welding body mounted beside the worktable. The upper surface of the worktable is provided with two sliding grooves perpendicular to the rotating shafts, and sliding guides that move along their length are provided within the sliding grooves. The device comprises a sliding block with a support plate at its upper end. A clamping screw that abuts against the worktable is threaded onto the support plate. A rotating disk is rotatably connected to the upper end of the support plate. The second concave block is disposed on the rotating disk. A fixing structure is provided between the rotating disk and the support plate. This device has the advantage of being able to clamp two iron frames at arbitrary angles. However, when processing different types of connecting parts, the layout and spacing between the fixing structures need to be redesigned, which greatly affects the production speed of the connecting parts. Therefore, an automatic welding device for iron frame bed connecting parts is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic welding device for iron frame bed connectors, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic welding device for iron frame bed connectors, including a support platform, a base plate fixedly connected to the top of the support platform, a bidirectional lead screw rotatably connected to the inner wall of the base plate, a movable plate threadedly connected to the circumferential surface of the bidirectional lead screw, a rotating rod rotatably connected to the inner wall of the movable plate, a lifting plate rotatably connected to the circumferential surface of the rotating rod, a rotating wheel fixedly connected to the circumferential surface of the rotating rod, a support frame fixedly connected to the top of the base plate, a fixing mechanism for improving the stability of the connectors during welding, a limiting mechanism for preventing the connectors from shifting during welding, and a fixing strip fixedly connected to the front of the support frame. When welding of the connectors begins, the distance between the two lifting plates can be increased, thus accommodating different models. Welding between connectors ensures a flat and tight fit during the welding process, preventing loosening or instability caused by dimensional mismatch. A motor is located on the left side of the bidirectional lead screw, which drives the lead screw to rotate. The surface of the moving plate is slidably connected to the inner wall of the base plate. The supporting plate supports the connectors. The rotating wheel adjusts the welding angle between the connectors. When welding connectors at different angles, the appropriate angle of the connecting plate can be adjusted to ensure that the connecting plates align at the correct angle, thereby improving the accuracy of the connectors. It can also flexibly adapt to different design requirements, ensuring that different models or types of connectors can be accurately welded. Whether it is a 90-degree right angle or other angles, adjusting the angle makes the welding more flexible and adaptable.

[0006] Preferably, the fixing mechanism includes a sliding rod, which is slidably connected to the inner wall of the support frame via a spring. A force-bearing plate is fixedly connected to the right side of the sliding rod, and a grooved plate is fixedly connected to the circumferential surface of the sliding rod. A T-shaped plate is threadedly connected to the circumferential surface of the bidirectional lead screw. An elastic telescopic rod is fixedly connected to the rear of the T-shaped plate, and a round rod is fixedly connected to the top of the telescopic end of the elastic telescopic rod. A movable rod is slidably connected to the inner wall of the fixing bar, and a T-shaped plate is connected to the circumferential surface of the movable rod. A fixing rod is fixedly connected to the inner wall of the T-shaped plate, and a pressing plate is rotatably connected to the inner wall of the fixing rod. During the adjustment of the welding angle, the grooved plate can be limited when the adjustment is completed, thereby supporting the left side of the plate and preventing the plate from being subjected to uneven forces, which could lead to structural instability. By supporting the rear of the lifting plate, the collapse or tilting of the plate can be effectively prevented, maintaining the stability of the plate during the welding process. The stability of the plate ensures precise alignment of the connectors and guarantees that the grooved plate can properly support the lifting plate during angle adjustments. The bottom of the T-shaped plate is slidably connected to the inner wall of the base plate, the bottom of the elastic telescopic rod is in contact with the top of the base plate, the circumferential surface of the round rod is in contact with the inner wall of the grooved plate, the right side of the force-bearing plate is in contact with the left side of the lifting plate, and the force-bearing plate is used to support the lifting plate. The top of the moving rod is equipped with a cylinder, and the moving rod will be driven by the cylinder to move. The inner wall of the support frame is slidably connected to the circumferential surface of the fixed rod. The extrusion plate is used to fix the connectors. When welding the support plate is required, the extrusion plate will contact the surface of the connector during its downward movement and can adapt to the angle of the connector surface to fix the connector, thereby further improving the welding accuracy of the connecting plate, increasing work efficiency, and ensuring the smooth progress of welding operations.

[0007] Preferably, the limiting mechanism includes an L-shaped block, which is fixedly connected to the circumferential surface of the fixing rod. A right-angle block is fixedly connected to the front of the support frame. A connecting rod is fixedly connected to the inner wall of the right-angle block by a spring. An L-shaped rod is slidably connected to the circumferential surface of the connecting rod. A slanted plate is fixedly connected to the rear of the L-shaped rod. A fixing platform is fixedly connected to the top of the support platform. A threaded rod is rotatably connected to the inner wall of the fixing platform. A U-shaped plate is threadedly connected to the circumferential surface of the threaded rod. A trapezoidal plate is fixedly connected to the bottom of the U-shaped plate. During fixing, when the slanted plate moves downward, it will contact the connecting plate whose placement position is offset, and the slanted plate will press the connecting plate into the appropriate position. This ensures that the connecting piece is in the correct position of the supporting plate and that the two connecting plates are aligned with each other, thereby preventing... In cases where welding deviations lead to errors, the L-shaped block pushes the L-shaped rod downwards during operation. The inclined panel corrects the misaligned connector. A motor is located at the rear of the threaded rod, driving it to rotate. The surface of the U-shaped plate slides against the inner wall of the fixed platform, and a trapezoidal plate is fixedly connected to the bottom of the U-shaped plate. After welding, this reduces manual intervention time, avoids delays caused by manual operation after welding, streamlines the production process, and improves overall production efficiency. Furthermore, welded connectors may require cooling time due to high temperatures. Manual operation could expose operators to hot components, potentially causing burns or other safety accidents. The automatic ejection function prevents personnel from contacting hot objects, ensuring safety.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This automatic welding device for iron frame bed connectors utilizes the coordinated operation of a support platform, base plate, bidirectional lead screw, moving plate, rotating rod, lifting plate, rotating wheel, support frame, and fixing strip. When welding connectors begins, the distance between the two lifting plates can be increased to accommodate welding of different connector models. This ensures that the connectors are flat and tightly joined during welding, preventing loosening or instability caused by dimensional mismatch. When welding connectors at different angles, the connecting plate can be adjusted to the appropriate angle to ensure correct alignment, thereby improving the accuracy of the connectors. It can also flexibly adapt to different design requirements, ensuring precise welding of different models or types of connectors. Whether it's a 90-degree right angle or other angles, adjusting the angle makes welding more flexible and adaptable.

[0010] 2. This automatic welding device for iron frame bed connectors, through the coordinated operation of sliding rods, grooved plates, force-bearing plates, T-shaped plates, elastic telescopic rods, and round rods, can limit the grooved plate when the welding angle is adjusted, thereby supporting the left side of the plate and preventing the plate from being subjected to uneven forces, which could lead to structural instability. By supporting the rear of the lifting plate, it can effectively prevent the plate from collapsing or tilting, maintain the stability of the plate during the welding process, ensure the precise docking of the connectors, and ensure that the grooved plate can properly support the lifting plate when the angle is adjusted.

[0011] 3. This automatic welding device for iron frame bed connectors, through the coordinated operation of the moving rod, T-shaped plate II, fixed rod, and extrusion plate, when welding is required on the pallet, the extrusion plate will contact the surface of the connector during its downward movement and can adaptively fix the connector by adjusting the angle of the connector surface, thereby further improving the welding accuracy of the connector, increasing work efficiency, and ensuring the smooth progress of welding operations.

[0012] 4. This automatic welding device for iron frame bed connectors, through the coordinated operation of L-shaped blocks, right-angle blocks, connecting rods, and L-shaped rods, ensures that when the inclined plate moves downward during fixing, it contacts the connecting plate whose placement position is offset, and the inclined plate itself presses the connecting plate into the appropriate position. This ensures that the connector is in the correct position of the supporting plate and that the two connecting plates are aligned with each other, thereby preventing welding deviations and errors.

[0013] 5. This automatic welding device for iron frame bed connectors, through the coordinated operation of inclined panels, fixed platforms, threaded rods, U-shaped plates, and trapezoidal plates, can reduce the time for manual intervention after welding, avoid delays caused by manual operation after welding, make the production process smoother, and improve the overall production efficiency. At the same time, the connectors after welding may need a period of cooling due to high temperature. During manual operation, operators are prone to contact with high-temperature components, which may cause burns or other safety accidents. The automatic ejection function can prevent personnel from contacting high-temperature objects and ensure safety. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-7 One embodiment of the present invention is: an automatic welding device for iron frame bed connectors, including a support platform 1, a base plate 2 fixedly connected to the top of the support platform 1, a bidirectional lead screw 3 rotatably connected to the inner wall of the base plate 2, a moving plate 4 threadedly connected to the circumferential surface of the bidirectional lead screw 3, a rotating rod 5 rotatably connected to the inner wall of the moving plate 4, a lifting plate 6 rotatably connected to the circumferential surface of the rotating rod 5, a rotating wheel 7 fixedly connected to the circumferential surface of the rotating rod 5, a support frame 8 fixedly connected to the top of the base plate 2, a fixing mechanism 9 for improving the stability of the connectors during welding, a limiting mechanism 10 for preventing the connectors from shifting during welding, and a fixing strip 11 fixedly connected to the front of the support frame 8;

[0024] When welding the connectors begins, the connectors are first placed on top of the support plate 6. If the connector volume is too large or the shape is different, the motor will start and drive the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 will pass through the bidirectional threaded groove on the surface, allowing the opposing moving plates 4 to move in opposite directions. The movement of the moving plate 4 to the left will drive the rotating rod 5 to move, and the movement of the rotating rod 5 will drive the support plate 6 to move, thereby opening the distance between the two support plates 6. This can handle the welding of different types of connectors and ensure that the connectors can be flat and tightly joined during the welding process, avoiding loosening or instability caused by size mismatch during the welding process.

[0025] A motor is installed on the left side of the bidirectional lead screw 3, and the bidirectional lead screw 3 will be driven by the motor to rotate. The surface of the moving plate 4 is slidably connected to the inner wall of the base plate 2. The lifting plate 6 is used to support the connecting parts. The rotating wheel 7 is used to adjust the welding angle between the connecting parts plates.

[0026] When welding connectors at different angles, the rotating wheel 7 is twisted, causing the rotating rod 5 to rotate. During the rotation of the rotating rod 5, the lifting plate 6 rotates, which in turn causes the connector placed on top of the lifting plate 6 to adjust its angle. This allows for the adjustment of the connector plate to the appropriate angle, ensuring that the connector plates are aligned at the correct angle, thereby improving the accuracy of the connectors. This is crucial for ensuring the stability and reliability of the final structure. At the same time, it can flexibly adapt to different design requirements, ensuring that different models or types of connectors can be welded accurately. Whether it is a 90-degree right angle or other angles, adjusting the included angle makes the welding more flexible and adaptable.

[0027] Working principle: When welding the connectors begins, the connectors are first placed on top of the support plate 6. When the connector volume is too large or the shape is different, the motor will start and drive the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 will pass through the bidirectional threaded groove on the surface, so that the relative moving plates 4 can move in opposite directions, thereby opening the distance between the two support plates 6. This can handle the welding of different types of connectors. When welding connectors at different angles, the rotating wheel 7 is twisted and the rotating rod 5 is driven to rotate, thereby adjusting the connecting plate to the appropriate angle and ensuring that the connecting plates are mated at the correct angle.

[0028] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the fixing mechanism 9 includes a sliding rod 91, which is slidably connected to the inner wall of the support frame 8 by a spring. A force-bearing plate 93 is fixedly connected to the right side of the sliding rod 91, and a grooved plate 92 is fixedly connected to the circumferential surface of the sliding rod 91. A T-shaped plate 94 is threadedly connected to the circumferential surface of the bidirectional lead screw 3. An elastic telescopic rod 95 is fixedly connected to the rear part of the T-shaped plate 94. A round rod 96 is fixedly connected to the top of the telescopic end of the elastic telescopic rod 95. A moving rod 97 is slidably connected to the inner wall of the fixing bar 11. A T-shaped plate 98 is connected to the circumferential surface of the moving rod 97. A fixing rod 99 is fixedly connected to the inner wall of the T-shaped plate 98. A pressing plate 910 is rotatably connected to the inner wall of the fixing rod 99.

[0029] During the adjustment of the welding angle, the counterclockwise rotation of the lifting plate 6 compresses the force plate 93, causing it to move to the left. This movement of the force plate 93 to the left moves the sliding rod 91 to the left and compresses the surface spring. The movement of the sliding rod 91 then moves the grooved plate 92, which in turn compresses the round rod 96. This downward pressure causes the round rod 96 to move downward, compressing the elastic telescopic rod 95. This compression of the grooved plate 92 when the adjustment is complete provides support to the left side of the lifting plate 6. To prevent the pallet from being subjected to uneven forces that could lead to structural instability, the rear of the support plate 6 is supported to effectively prevent the pallet from collapsing or tilting, maintaining the stability of the pallet during welding and ensuring precise alignment of the connectors. Simultaneously, when adjusting the spacing of the support plate 6, the rotation of the bidirectional lead screw 3 synchronously moves the T-shaped plate 94, which in turn moves the elastic telescopic rod 95, which in turn moves the round rod 96. This ensures that the grooved plate 92 can properly support the support plate 6 during angle adjustments.

[0030] The bottom of the T-shaped plate 94 is slidably connected to the inner wall of the base plate 2, the bottom of the elastic telescopic rod 95 is in contact with the top of the base plate 2, the circumferential surface of the round rod 96 is in contact with the inner wall of the groove plate 92, the right side of the force plate 93 is in contact with the left side of the lifting plate 6, and the force plate 93 is used to support the lifting plate 6. The top of the moving rod 97 is equipped with a cylinder, and the moving rod 97 will be driven by the cylinder to move. The inner wall of the support frame 8 is slidably connected to the circumferential surface of the fixed rod 99, and the pressing plate 910 is used to fix the connecting parts.

[0031] When welding is required on the pallet, the downward movement of the cylinder will cause the moving rod 97 to move downward, which in turn will cause the T-shaped plate 98 to move downward, which in turn will cause the fixing rod 99 to move downward, which in turn will cause the pressing plate 910 to move downward. During the downward movement of the pressing plate 910, it will come into contact with the surface of the connector and can adapt to the angle of the connector surface to fix the connector, thereby further improving the welding accuracy of the connector, improving work efficiency, and ensuring the smooth progress of the welding operation.

[0032] Working principle: During the adjustment of the welding angle, the counterclockwise rotation of the lifting plate 6 compresses the force plate 93, causing it to move to the left. This movement of the force plate 93 to the left moves the sliding rod 91 to the left and compresses the surface spring. The movement of the sliding rod 91 then moves the groove plate 92, which can limit the groove plate 92 when the adjustment is complete. This supports the left side of the lifting plate 6, preventing uneven force on the plate and thus structural instability. When welding is required, the downward movement of the cylinder moves the moving rod 97 downward. This downward movement of the moving rod 97 moves the T-shaped plate 98 downward, which in turn moves the fixing rod 99 downward. This action adapts to the angle of the connecting parts surface to fix the connecting parts, thereby further improving the welding accuracy of the connecting plates, increasing work efficiency, and ensuring the smooth progress of the welding operation.

[0033] The limiting mechanism 10 includes an L-shaped block 101, which is fixedly connected to the circumferential surface of the fixed rod 99. A right-angle block 102 is fixedly connected to the front of the support frame 8. A connecting rod 103 is fixedly connected to the inner wall of the right-angle block 102 by a spring. An L-shaped rod 104 is slidably connected to the circumferential surface of the connecting rod 103. An inclined plate 105 is fixedly connected to the rear of the L-shaped rod 104. A fixed platform 106 is fixedly connected to the top of the support platform 1. A threaded rod 107 is rotatably connected to the inner wall of the fixed platform 106. A U-shaped plate 108 is threadedly connected to the circumferential surface of the threaded rod 107. A trapezoidal plate 109 is fixedly connected to the bottom of the U-shaped plate 108.

[0034] During the fixing process, the downward movement of the fixing rod 99 will cause the L-shaped block 101 to move downward. The downward movement of the L-shaped block 101 will contact the top of the L-shaped rod 104, forcing the L-shaped rod 104 to move downward. The downward movement of the L-shaped rod 104 will cause the inclined plate 105 to move downward. When the inclined plate 105 moves downward, it will contact the connecting plate whose placement position is offset, and squeeze the connecting plate into the appropriate position through its own inclined surface. This ensures that the connecting part is in the correct position of the supporting plate 6 and that the two connecting plates are aligned with each other, thereby preventing welding deviations and welding errors.

[0035] During operation, the L-shaped block 101 will push the L-shaped rod 104 downward. The inclined plate 105 is used to correct the offset connector. A motor is provided at the rear of the threaded rod 107, and the threaded rod 107 will be driven by the motor to rotate. The surface of the U-shaped plate 108 is slidably connected to the inner wall of the fixed platform 106. A trapezoidal plate 109 is fixedly connected to the bottom of the U-shaped plate 108.

[0036] After welding is completed, the motor starts and drives the threaded rod 107 to rotate. The rotation of the threaded rod 107 drives the U-shaped plate 108 to move forward through the threaded groove on its surface. The movement of the U-shaped plate 108 drives the trapezoidal plate 109 to move forward, thereby automatically pushing out the connector on the surface of the support plate 6. This reduces the time for manual intervention, avoids delays caused by manual operation after welding, makes the production process smoother, and improves the overall production efficiency. At the same time, the connector after welding may need a period of cooling due to high temperature. During manual operation, operators are prone to contact with high-temperature parts, which may cause burns or other safety accidents. The automatic push-out function can prevent personnel from contacting high-temperature objects and ensure safety.

[0037] Working principle: During fixing, the downward movement of the fixing rod 99 will cause the L-shaped block 101 to move downward. The downward movement of the L-shaped block 101 will contact the top of the L-shaped rod 104, forcing the L-shaped rod 104 to move downward. When the inclined plate 105 moves downward, it will contact the connecting plate whose placement position is offset, and squeeze the connecting plate into the appropriate position through its own inclined surface, thereby ensuring that the connector is in the correct position of the supporting plate 6. After welding is completed, the rotation of the threaded rod 107 will drive the U-shaped plate 108 to move forward through the threaded groove on the surface. The movement of the U-shaped plate 108 will drive the trapezoidal plate 109 to move forward, thereby automatically pushing out the connector on the surface of the supporting plate 6, which can reduce the time of manual intervention.
