Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, specifically a steel mesh welding positioning device. Background Technology

[0002] Reinforcing mesh, also known as welded steel mesh, steel wire mesh, or steel mesh sheet, is made of high-quality low-carbon steel wire or hot-rolled round steel through a process of welding. It features a flat mesh surface, uniform mesh size, strong welds, good local machinability, stability, and strong corrosion resistance. Reinforcing mesh is widely used in construction engineering and related industries, especially in bridges, roads, and building foundations, where it plays a crucial role.

[0003] Traditional steel mesh welding methods are usually done manually, with operators holding welding torches to weld the intersections of the steel mesh one by one. This method is not only inefficient, but also makes it difficult to guarantee the welding quality, as the operator's skill level and fatigue level will affect the welding quality. In addition, manual operation also poses safety hazards, as operators are prone to injury from sparks, high temperature radiation, etc. during the welding process.

[0004] To overcome the shortcomings of traditional methods, the industry has begun to explore automated and intelligent rebar mesh welding and positioning devices. These devices typically use automated equipment such as robotic arms and servo motors to precisely weld and position the rebar mesh through preset programs. However, these devices still have some problems in practical applications, such as the rebars easily shifting during the welding process and high equipment costs. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a steel mesh welding positioning device to solve the technical problems of steel bars easily shifting and high equipment costs in some existing devices during the welding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rebar mesh welding positioning device, comprising a workbench, a first movable plate slidably disposed on the top of the workbench, a first fixed frame fixedly connected above the first movable plate, multiple sets of first telescopic rods installed on the top of the first movable plate, a second fixed frame fixedly installed at the output end of the first telescopic rods, multiple sets of clamping structures disposed on the first fixed frame and the second fixed frame, a set of cylinders used in conjunction with the clamping structures disposed within each of the first fixed frame and the second fixed frame, the multiple sets of clamping structures on the first fixed frame and the second fixed frame respectively clamping and connecting a second rebar and a first rebar, the first rebar and the second rebar being perpendicular to each other, a support frame disposed on the top of the workbench, a driving structure disposed on the top of the support frame, a second movable plate used in conjunction with the driving structure disposed on the top of the support frame, and multiple sets of welding devices disposed at the bottom of the second movable plate, the number of the multiple sets of welding devices being the same as the number of intersection points of the first rebar and the second rebar.

[0007] By adopting the above technical solution, during use, the second fixed frame is moved upward by the first telescopic rod, at which point the distance between the first and second fixed frames is at its maximum. Then, workers can load the materials, placing the first and second reinforcing bars sequentially onto the clamping structure. After the reinforcing bars are placed, the second fixed frame is lowered by the first telescopic rod. Since the second fixed frame is larger than the first fixed frame, the first reinforcing bar can fully contact the second reinforcing bar. The clamping structure, located on the first and second fixed frames and used in conjunction with a cylinder, can firmly clamp the first and second reinforcing bars, thus ensuring their proper functioning during welding. The stability of the welding device is improved by having the same number of welding devices as the number of intersections between the first and second reinforcing bars, enabling simultaneous welding of these intersections and significantly improving welding efficiency. The drive structure, mounted on the top of the support frame, can drive the second movable plate and the welding devices on it to move precisely, ensuring accurate welding position. The first telescopic rod can adjust the distance between the first and second fixed frames to accommodate reinforcing bars of different lengths. The cylinder, located within the first and second fixed frames, assists the clamping structure in clamping the reinforcing bars more firmly, preventing slippage or detachment during welding, thus improving the practicality and flexibility of the entire reinforcing mesh welding positioning device.

[0008] The present invention is further configured such that the clamping structure includes a first movable rod, a first rack, a gear, a second movable rod, a second rack, multiple sets of clamping blocks, and a connecting rod. The first rack is fixed to the inner side of the first movable rod, the second rack is fixed to the inner side of the second movable rod, the first rack is located above the second rack, a gear is provided between the first rack and the second rack, the connecting rod is fixed to the bottom of the second rack, and one end of the connecting rod is fixedly connected to the output end of the cylinder.

[0009] By adopting the above technical solution, when the cylinder drives the connecting rod to move, since the connecting rod is fixedly connected to the second rack, it will drive the second rack to move. Since the gear meshes with both the first and second racks, the movement of the second rack will drive the gear to rotate, thereby driving the first rack and the first movable rod connected to it to move. This allows the first and second movable rods to clamp synchronously, so that the clamping block can clamp and fix the first and second reinforcing bars. By adjusting the output force of the cylinder, the moving distance and clamping effect of the connecting rod and the second rack can be precisely controlled, making it suitable for use with reinforcing bars of different sizes.

[0010] The present invention is further configured such that a lead screw is rotatably connected to the top of the workbench in a symmetrical structure, a support block is fixedly installed on one side of the workbench, a motor is symmetrically arranged above the support block, the output end of the motor is fixedly connected to the lead screw, and the lead screw movably passes through the first movable plate.

[0011] By adopting the above technical solution, the motor drives the lead screw to rotate, which can precisely control the movement of the first movable plate on the worktable. The lead screw is symmetrically connected to the top of the worktable, making the entire transmission structure more stable. At the same time, the fixed installation of the support block also enhances the stability of the motor and the lead screw, thereby ensuring the reliability and durability of the transmission, and enabling the first movable plate to slide flexibly and smoothly on the worktable.

[0012] The present invention is further configured such that a connecting block is bolted to the bottom of the workbench, a second telescopic rod is provided inside the connecting block, and multiple sets of top columns are fixedly connected to the output end of the second telescopic rod. The top columns are provided with arc-shaped grooves for use with reinforcing bars, and the workbench and the first movable plate are both provided with first slots for use with the top columns.

[0013] By adopting the above technical solution, during installation, the connecting block and the second telescopic rod are fixed to the bottom of the workbench with bolts. When the welding device welds at the junction of the first and second reinforcing bars, the top column is driven to move upward by the second telescopic rod until the arc-shaped groove on the top column contacts the reinforcing bar. The top column can exert an upward squeezing effect on the reinforcing bar, so that the reinforcing bar can better cooperate with the welding structure for welding. The first slot allows the top column to be raised and lowered flexibly, ensuring that it can be accurately positioned during the raising and lowering process.

[0014] The present invention is further provided that the first fixed frame and the second fixed frame are provided with sliding grooves that cooperate with the clamping structure and the connecting rod.

[0015] By adopting the above technical solution, the set slide provides a stable sliding track for the clamping structure and the connecting rod, ensuring the stability and accuracy of the clamping structure and the connecting rod during the movement process, and preventing operational errors caused by offset or shaking.

[0016] The present invention is further configured such that the gear is located between the slide grooves, and the gear is rotatably connected to the slide grooves.

[0017] By adopting the above technical solution, when the gear is rotatably connected to the slide, the rotational motion of the gear is restricted and guided by the slide, making the entire mechanism more stable and reliable during operation.

[0018] The present invention is further configured such that the bottom of the workbench is provided with multiple sets of support legs, and the clamping structure is provided with a second slot, the second slot being a semi-circular structure.

[0019] By adopting the above technical solution, the supporting legs can make the entire positioning device stand stably on the ground for use, and the second slot on the two clamping structure can provide a more stable clamping effect.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model adjusts the distance between the first fixed frame and the second fixed frame by the first telescopic rod, which facilitates material feeding. The clamping structure cooperates with the cylinder to firmly clamp the first and second steel bars, ensuring welding stability. The number of welding devices is the same as the number of intersections of the steel bars, which improves welding efficiency. The driving structure drives the welding devices to move precisely, ensuring accurate welding position. The entire device can adapt to steel bars of different sizes, prevent steel bars from sliding or falling off, and improve practicality and flexibility.

[0022] 2. This utility model, when the cylinder drives the connecting rod to move, because the connecting rod is fixedly connected to the second rack, will drive the second rack to move. Since the gear meshes with both the first and second racks, the movement of the second rack will drive the gear to rotate, thereby driving the first rack and the first movable rod connected to it to move. This allows the first and second movable rods to clamp synchronously, so that the clamping block can clamp and fix the first and second steel bars. By adjusting the output force of the cylinder, the moving distance and clamping effect of the connecting rod and the second rack can be precisely controlled, making it suitable for use with steel bars of different sizes.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] A steel mesh welding positioning device, such as Figure 1-7 As shown, the system includes a workbench 1, a first movable plate 22 slidably mounted on the top of the workbench 1, a first fixed frame 5 fixedly connected above the first movable plate 22, multiple sets of first telescopic rods 6 mounted on the top of the first movable plate 22, a second fixed frame 7 fixedly mounted at the output end of the first telescopic rods 6, multiple sets of clamping structures 13 mounted on the first fixed frame 5 and the second fixed frame 7, and a set of cylinders 23 used in conjunction with the clamping structures 13 in both the first fixed frame 5 and the second fixed frame 7. The first fixed frame 5 and the second fixed frame 7, in conjunction with the multiple sets of clamping structures 13, respectively clamp and connect a second reinforcing bar 10 and a first reinforcing bar 8. The first reinforcing bar 8 and the second reinforcing bar 10 are perpendicular to each other. A support frame 3 is mounted on the top of the workbench 1, a drive structure 4 is mounted on the top of the support frame 3, a second movable plate 15 used in conjunction with the drive structure 4 is mounted on the top of the support frame 3, and multiple sets of welding devices 14 are mounted on the bottom of the second movable plate 15. The number of welding devices 14 is the same as the number of intersection points between the first reinforcing bar 8 and the second reinforcing bar 10.

[0034] In use, the second fixed frame 7 is moved upward by the first telescopic rod 6, at which point the distance between the first fixed frame 5 and the second fixed frame 7 is at its maximum. Then, the workers can load the materials, placing the first reinforcing bar 8 and the second reinforcing bar 10 onto the clamping structure 13 in sequence. After the reinforcing bars are placed, the second fixed frame 7 is lowered by the first telescopic rod 6. Since the second fixed frame 7 is larger than the first fixed frame 5, the first reinforcing bar 8 can fully contact the second reinforcing bar 10. The clamping structure 13 is set on the first fixed frame 5 and the second fixed frame 7 and works in conjunction with the cylinder 23 to firmly clamp the first reinforcing bar 8 and the second reinforcing bar 10, thereby ensuring their stability during the welding process. Qualitatively, the number of welding devices 14 is the same as the number of intersections between the first reinforcing bar 8 and the second reinforcing bar 10, enabling simultaneous welding of these intersections and significantly improving welding efficiency. The drive structure 4 is installed on the top of the support frame 3 and can drive the second movable plate 15 and the welding devices 14 on it to move precisely, ensuring accurate welding position. The first telescopic rod 6 can adjust the distance between the first fixed frame 5 and the second fixed frame 7 to accommodate reinforcing bars of different lengths. The cylinder 23 is set inside the first fixed frame 5 and the second fixed frame 7 and can assist the clamping structure 13 in clamping the reinforcing bars more firmly, preventing slippage or detachment during welding, thus improving the practicality and flexibility of the entire reinforcing bar mesh welding positioning device.

[0035] Furthermore, when the cylinder 23 drives the connecting rod 30 to move, since the connecting rod 30 is fixedly connected to the second rack 28, it will drive the second rack 28 to move. Since the gear 26 meshes with both the first rack 25 and the second rack 28, the movement of the second rack 28 will drive the gear 26 to rotate, thereby driving the first rack 25 and the first movable rod 24 connected to it to move. This allows the first movable rod 24 and the second movable rod 27 to perform synchronous clamping actions, so that the clamping block 29 can clamp and fix the first steel bar 8 and the second steel bar 10. By adjusting the output force of the cylinder 23, the moving distance and clamping effect of the connecting rod 30 and the second rack 28 can be precisely controlled, making it suitable for steel bars of different sizes. The motor 11 drives the lead screw 9 to rotate, which can precisely control the movement of the first movable plate 22 on the worktable 1. The symmetrical structure is rotated and connected to the top of the workbench 1, making the entire transmission structure more stable. At the same time, the fixed installation of the support block 12 also enhances the stability of the motor 11 and the lead screw 9, thereby ensuring the reliability and durability of the transmission. This allows the first movable plate 22 to slide flexibly and smoothly on the workbench 1. During installation, the connecting block 17 and the second telescopic rod 16 are fixed to the bottom of the workbench 1 with bolts. When the welding device 14 welds the junction of the first steel bar 8 and the second steel bar 10, the second telescopic rod 16 drives the top column 21 to move upward until the arc groove on the top column 21 contacts the steel bar. The top column 21 can exert an upward squeezing effect on the steel bar, allowing the steel bar to better cooperate with the welding structure for welding. The first slot 18 allows the top column 21 to move up and down flexibly, ensuring that it can be accurately positioned during the lifting process.

[0036] In this embodiment, the slide groove 20 provides a stable sliding track for the clamping structure 13 and the connecting rod 30, ensuring the stability and accuracy of the clamping structure 13 and the connecting rod 30 during movement, and preventing operational errors caused by offset or shaking. When the gear 26 is rotatably connected to the slide groove 20, the rotational movement of the gear 26 is restricted and guided by the slide groove 20, making the entire mechanism more stable and reliable during operation. Finally, the support leg 2 can make the entire positioning device stand stably on the ground for use. The second slot 19 opened on the clamping structure 13 can provide a more stable clamping effect.
