Technical Field
[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for welding steel reinforcement skeletons. Background Technology
[0002] A steel reinforcement cage is a complete grid formed by combining steel bars, commonly known as a "steel cage" or "steel mesh." It is primarily used to confine concrete and improve the overall integrity of concrete structures. A steel reinforcement cage generally refers to a three-dimensional assembly of steel bars, such as the steel bars within beams and columns, while a steel mesh refers to a two-dimensional assembly of steel bars, such as the longitudinal and transverse steel bars within floor slabs. Existing steel reinforcement cages require clamping and fixing the transverse and longitudinal steel bars during fabrication. However, when transverse steel bars are wrapped around other transverse steel bars, they are easily pulled and deformed, resulting in inconsistent overall dimensions and lower quality. Furthermore, there are numerous contact points between the transverse and longitudinal steel bars, leading to incomplete welds when manually welded one by one.
[0003] For example, the rebar clamping device disclosed in the authorization announcement number CN219638248U includes a first rebar and a second rebar, and a circular clamping tube for connecting the first rebar and the second rebar. A connecting block is provided in the middle of the inside of the circular clamping tube. A positioning mechanism is provided between the outer wall of the first rebar and the inner wall of the circular clamping tube, and a positioning mechanism is also provided between the outer wall of the second rebar and the inner wall of the circular clamping tube.
[0004] Although it achieves the goal of ensuring that the joint between the first and second reinforcing bars is located in the middle of the circular clamping tube through the connecting block, and ensuring that the first and second reinforcing bars are on the same axis after docking through the positioning mechanism, the arc-shaped rubber block is pressed against the outside of the reinforcing bar by the fastening bolts, thereby increasing the friction between the arc-shaped rubber block and the reinforcing bar, and effectively fixing the positions of the first and second reinforcing bars and the circular clamping tube, it realizes the clamping and docking of the first and second reinforcing bars.
[0005] However, the existing clamping devices of this type are not conducive to convenient multi-position moving welding operations of the reinforcing steel cage during use, and are not convenient for quick positioning, clamping and fixing of the reinforcing steel cage, which affects the welding range of the reinforcing steel cage. Single-angle clamping is not convenient for welding the entire range of the reinforcing steel cage, which greatly affects the welding efficiency of the reinforcing steel cage. Utility Model Content
[0006] The purpose of this utility model is to provide a clamping device for welding steel reinforcement cages, so as to solve the problems mentioned in the background art, such as the inconvenience of the clamping device for convenient multi-position moving welding operations of steel reinforcement cages, the inconvenience of quick positioning and clamping of steel reinforcement cages, which affects the welding range of steel reinforcement cages, and the inconvenience of single-angle clamping for welding the entire range of steel reinforcement cages, which affects the welding efficiency of steel reinforcement cages.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for welding steel reinforcement cages, comprising a base and an X-screw moving assembly. The X-screw moving assembly is mounted on the top of the base. A Y-screw moving assembly is movably mounted on the outer wall of the X-screw moving assembly. A Z-screw moving assembly is movably mounted on the outer wall of the Y-screw moving assembly. A welding torch is movably mounted on the outer wall of the Z-screw moving assembly. A base plate is mounted on the outer wall of the base. A sliding frame is mounted on the top of the base below the X-screw moving assembly. A fixed frame is mounted on the outer wall of the base plate on one side of the sliding frame. A first rotating seat is mounted on the top of the sliding frame. A second rotating seat is mounted on the top of the fixed frame.
[0008] Preferably, a central shaft is installed at the inner center of both the first rotating seat and the second rotating seat, a clamping frame is installed on the outer wall of the central shaft, and a first motor is installed at the top of the clamping frame.
[0009] Preferably, the output end of the first motor is equipped with a bidirectional threaded rod, the surface of the bidirectional threaded rod is symmetrically fitted with a bidirectional threaded sleeve, and the outer wall of the bidirectional threaded sleeve is equipped with an arc-shaped clamping arm.
[0010] Preferably, a second motor is installed on the outer wall of the base plate near the fixing frame, and an extension shaft is installed at the output end of the second motor.
[0011] Preferably, first pulleys are symmetrically installed on the outer wall of the extended shaft, and second pulleys are installed on the outer wall of the end of the central shaft away from the bidirectional threaded rod, and belts are movably installed on the outer wall of each of the second pulleys.
[0012] Preferably, the surface of the extended shaft is provided with a keyway, and a positioning key is installed inside the first pulley on one side of the keyway, and the positioning key is slidably connected to the keyway.
[0013] Preferably, a cylinder is installed on the outer wall of the base below the Z-screw moving assembly, a transmission rod is installed at the output end of the cylinder, and the transmission rod is connected to the sliding frame. A linkage plate is installed at the bottom end of the sliding frame on one side of the transmission rod, and a linkage wheel is installed at the bottom end of the linkage plate.
[0014] Preferably, a linkage block is movably fitted onto the surface of the extended shaft on one side of the linkage wheel, and the linkage block is fixedly connected to the first pulley. The surface of the linkage block is provided with an annular groove, and the annular groove is movably connected to the linkage wheel.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the clamping device not only realizes convenient multi-position moving welding operation of the steel reinforcement cage, and facilitates the quick positioning, clamping and fixing of the steel reinforcement cage, but also increases the welding range of the steel reinforcement cage, avoids the inability to weld the entire range of the steel reinforcement cage from a single angle, and improves the welding efficiency of the steel reinforcement cage.
[0016] The worker first places the rebar cage into the arc-shaped clamping arm and clamps it. The X-screw moving component drives the Y-screw moving component, the Z-screw moving component, and the welding torch to move laterally to the appropriate position. The Y-screw moving component drives the Z-screw moving component and the welding torch to move longitudinally to the appropriate position. The Z-screw moving component drives the welding torch to move, and the welding torch is turned on to weld the rebar cage. The rebar cage is then placed into the arc-shaped clamping arm, and the first motor drives the bidirectional threaded rod to rotate. Under the threaded connection between the bidirectional threaded rod and the bidirectional threaded sleeve, the bidirectional threaded sleeve moves. The bidirectional threaded sleeve drives the arc-shaped clamping arm to move. The two sets of arc-shaped clamping arms work together to clamp the rebar cage, realizing convenient multi-position moving welding operations for the rebar cage by the clamping device, which facilitates the rapid positioning, clamping, and fixing of the rebar cage.
[0017] The second motor drives the extended shaft to rotate, which in turn drives the first pulley to rotate. The first pulley, via a belt, drives the second pulley to rotate. With the support of the first rotating seat on the central shaft, the second pulley drives the central shaft to rotate, which in turn drives the clamping frame to rotate. The clamping frame then drives the arc-shaped clamping arm and the reinforcing steel skeleton to rotate, thus enabling the clamping device to conveniently adjust the position of the reinforcing steel skeleton by rotation. This increases the welding range of the reinforcing steel skeleton and avoids the inability to weld the entire range of the reinforcing steel skeleton from a single angle.
[0018] By opening the cylinder, the cylinder, supported by the base, drives the transmission rod to move. The transmission rod then drives the sliding frame to move, which slides on the surface of the base. The sliding frame drives the linkage plate to move, which in turn drives the linkage wheel to move synchronously. With the cooperation of the linkage wheel and the annular groove, the linkage block moves laterally. The linkage block then drives the first pulley to move laterally. With the cooperation of the positioning key and the keyway, the first pulley slides on the surface of the extended shaft. This allows for easy clamping and fixing of steel reinforcement cages of different lengths, enabling the clamping device to adjust and fix steel reinforcement cages of different lengths. This increases the clamping support range of the steel reinforcement cage and improves the welding efficiency of the steel reinforcement cage. Attached Figure Description

[0028] Please see Figure 1-7This utility model provides an embodiment of a clamping device for welding steel reinforcement cages, comprising a base 1 and an X-screw moving assembly 2. The X-screw moving assembly 2 is mounted on the top of the base 1. A Y-screw moving assembly 3 is movably mounted on the outer wall of the X-screw moving assembly 2.

A base plate 6 is mounted on the outer wall of the base 1. A sliding frame 7 is mounted on the top of the base 1 below the X-screw moving assembly 2. The base plate 6 is mounted on one side of the sliding frame 7. A fixed frame 8 is installed on the outer wall, a first rotating seat 9 is installed at the top of the sliding frame 7, a second rotating seat 10 is installed at the top of the fixed frame 8, a central shaft 11 is installed at the center of the first rotating seat 9 and the second rotating seat 10, a clamping frame 12 is installed on the outer wall of the central shaft 11, a first motor 13 is installed at the top of the clamping frame 12, a bidirectional threaded rod 15 is installed at the output end of the first motor 13, a bidirectional threaded sleeve 14 is symmetrically fitted on the surface of the bidirectional threaded rod 15, and an arc-shaped clamping arm 16 is installed on the outer wall of the bidirectional threaded sleeve 14.
[0029] The worker first places the rebar cage into the arc-shaped clamping arm 16 and clamps it. Then, the X-screw moving assembly 2 is opened, which drives the Y-screw moving assembly 3, the Z-screw moving assembly 4, and the welding torch 5 to move laterally to the appropriate position. The Y-screw moving assembly 3 is then opened, which drives the Z-screw moving assembly 4 and the welding torch 5 to move longitudinally to the appropriate position. The Z-screw moving assembly 4 is then opened, which drives the welding torch 5 to move to the appropriate height. The welding torch 5 is then used to weld the rebar cage. The rebar cage is then placed into the arc-shaped clamping arm 16, and the first motor 13 is turned on. With the support of the clamping frame 12, the first motor 13 drives the bidirectional threaded rod 15 to rotate. Under the threaded connection between the bidirectional threaded rod 15 and the bidirectional threaded sleeve 14, the bidirectional threaded sleeve 14 is moved. The bidirectional threaded sleeve 14 drives the arc-shaped clamping arm 16 to move. The two sets of arc-shaped clamping arms 16 work together to clamp the rebar cage, realizing convenient multi-position moving welding operations for the rebar cage using the clamping device, which facilitates the rapid positioning, clamping, and fixing of the rebar cage.
[0030] A second motor 17 is installed on the outer wall of the base plate 6 near the fixed frame 8. An extended shaft 18 is installed at the output end of the second motor 17. First pulleys 21 are symmetrically installed on the outer wall of the extended shaft 18. Second pulleys 23 are installed on the outer wall of the end of the central shaft 11 away from the bidirectional threaded rod 15. Belts 22 are movably installed on the outer wall of the second pulleys 23. A keyway 19 is provided on the surface of the extended shaft 18. A positioning key 20 is installed inside the first pulley 21 on one side of the keyway 19, and the positioning key 20 is slidably connected to the keyway 19.
[0031] When the second motor 17 is turned on, it drives the extension shaft 18 to rotate under the support of the base plate 6. With the cooperation of the positioning key 20 and the keyway 19, the extension shaft 18 drives the first pulley 21 to rotate. The first pulley 21 drives the second pulley 23 to rotate via the belt 22. With the support of the first rotating seat 9 on the central shaft 11, the second pulley 23 drives the central shaft 11 to rotate. The central shaft 11 drives the clamping frame 12 to rotate. The clamping frame 12 drives the arc-shaped clamping arm 16 and the steel reinforcement skeleton to rotate, realizing the convenient rotation adjustment of the position of the clamping device on the steel reinforcement skeleton, increasing the welding range of the steel reinforcement skeleton, and avoiding the inability to weld the entire range of the steel reinforcement skeleton from a single angle.
[0032] A cylinder 24 is installed on the outer wall of the base 1 below the Z-screw moving assembly 4. A transmission rod 25 is installed at the output end of the cylinder 24 and is connected to the sliding frame 7. A linkage plate 26 is installed at the bottom of the sliding frame 7 on one side of the transmission rod 25. A linkage wheel 27 is installed at the bottom of the linkage plate 26. A linkage block 28 is movably fitted on the surface of the extension shaft 18 on one side of the linkage wheel 27 and is fixedly connected to the first pulley 21. An annular groove 29 is provided on the surface of the linkage block 28 and is movably connected to the linkage wheel 27.
[0033] When cylinder 24 is opened, it drives transmission rod 25 to move under the support of base 1. Transmission rod 25 drives sliding frame 7 to move. Sliding frame 7 slides on the surface of base 1. Sliding frame 7 drives linkage plate 26 to move. Linkage plate 26 drives linkage wheel 27 to move synchronously. With the cooperation of linkage wheel 27 and annular groove 29, linkage block 28 moves laterally. Linkage block 28 drives first pulley 21 to move laterally. With the cooperation of positioning key 20 and keyway 19, first pulley 21 slides on the surface of extension shaft 18. When the distance between sliding frame 7 and fixed frame 8 is adjusted, it prevents first pulley 21 from failing to move laterally, thus preventing the first pulley from failing to move. The pulley 21, belt 22, central shaft 11, and arc-shaped clamping arm 16 rotate. When the second motor 17 drives the arc-shaped clamping arm 16 to rotate, the extended shaft 18 drives the first pulley 21 and linkage block 28 to rotate synchronously. The linkage wheel 27 slides and supports the annular groove 29. This ensures that the first pulley 21, linkage block 28, and belt 22 can move laterally while also ensuring that the rotation of the first pulley 21 is not interfered with. This facilitates the clamping and fixing of steel reinforcement cages of different lengths, realizes the adjustable clamping and fixing of steel reinforcement cages of different lengths, increases the clamping and support range of the steel reinforcement cage, and improves the welding efficiency of the steel reinforcement cage.
[0034] In this embodiment, during use: First, the worker places the reinforcing steel cage into the arc-shaped clamping arm 16 and clamps it. The X-screw moving assembly 2 drives the Y-screw moving assembly 3, the Z-screw moving assembly 4, and the welding torch 5 to move laterally to a suitable position. The Y-screw moving assembly 3 drives the Z-screw moving assembly 4 and the welding torch 5 to move longitudinally to a suitable position. The Z-screw moving assembly 4 drives the welding torch 5 to move to a suitable height, and the welding torch 5 is opened to weld the reinforcing steel cage. The reinforcing steel cage is then placed into the arc-shaped clamping arm 16, and the first motor 13 drives bidirectional... The threaded rod 15 rotates, driving the double-threaded sleeve 14 to move under the threaded connection between the double-threaded rod 15 and the double-threaded sleeve 14. The double-threaded sleeve 14 drives the arc-shaped clamping arm 16 to move, and the two sets of arc-shaped clamping arms 16 cooperate to clamp the steel reinforcement skeleton. The second motor 17, supported by the base plate 6, drives the extension shaft 18 to rotate. With the cooperation of the positioning key 20 and the keyway 19, the extension shaft 18 drives the first pulley 21 to rotate. The first pulley 21 drives the second pulley 23 to rotate via the belt 22. The first rotating seat 9 supports the central shaft 11. With the support of the second pulley 23, the central shaft 11 rotates, which in turn rotates the clamping frame 12. The clamping frame 12 then rotates the arc-shaped clamping arm 16 and the steel frame. Supported by the base 1, the cylinder 24 moves the transmission rod 25, which in turn moves the sliding frame 7. The sliding frame 7 slides on the surface of the base 1, moving the linkage plate 26. The linkage plate 26 then moves the linkage wheel 27 synchronously. With the cooperation of the linkage wheel 27 and the annular groove 29, the linkage block 28 moves laterally, which in turn moves the first pulley 21 laterally. The first pulley 21 slides on the surface of the extension shaft 18 with the cooperation of the positioning key 20 and the keyway 19. When the distance between the sliding frame 7 and the fixed frame 8 is adjusted, it prevents the first pulley 21 from being unable to move laterally, which would prevent the first pulley 21, belt 22, central shaft 11, and arc-shaped clamping arm 16 from rotating. When the second motor 17 drives the arc-shaped clamping arm 16 to rotate, the extension shaft 18 drives the first pulley 21 and the linkage block 28 to rotate synchronously, so as to facilitate the clamping and fixing of steel skeletons of different lengths, thus completing the use of the clamping device.
