Technical Field

[0001] This utility model relates to the technical field of steel structure welding and butt welding machines, and in particular to a rapid butt welding device for welding steel structural components. Background Technology

[0002] Steel structure is a commonly used building material, and it often requires welding during use. In order to improve the welding accuracy, steel structure welding and butt welding machines are usually used to join steel structures together.

[0003] Existing steel structure welding and butt welding machines, such as the Chinese utility model patent CN221538661U (authorization announcement number: A quick butt welding device for steel structure welding), represent a class of prior art whose main structure includes a rotating cylinder, a positioning rod, a sliding block, and a limiting seat. The rotating cylinder rotates the steel structure, the positioning rod and the limiting seat cooperate to clamp and fix the steel structure, and the sliding block butts the steel structure.

[0004] However, the existing technology and equipment still have the following problems when in use: the existing machines are prone to causing the steel structure to tilt when clamping it, resulting in large gaps at the joints of the steel structure and poor welding quality. Furthermore, the existing machines only drive the steel structure to rotate from one side, which can easily cause the steel structure to break during rotational welding, resulting in poor welding effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a quick-connection device for welding steel structural components. It uses a three-jaw chuck to center and clamp the steel structure, preventing the steel structure from tilting and creating gaps, thus improving the welding quality. Furthermore, it uses a synchronous rotation device to drive both sides of the steel structure to rotate synchronously, reducing the torque on the welding position of the steel structure, preventing the steel structure from breaking during welding, and improving the welding effect.

[0006] This utility model discloses a rapid welding device for steel structure components, comprising a machine body; it also includes a clamping device, two three-jaw chucks, a synchronous rotation device, a detection device, and a supporting device. The clamping device, detection device, and supporting device are all mounted on the machine body, and the two three-jaw chucks and the synchronous rotation device are all mounted on the clamping device.

The bracket 21 is provided with a mounting groove 2 below its own mounting groove 1. The bracket 27 is provided with a mounting groove 3, which is larger than the mounting groove 2, at the coaxial position below its own mounting groove 1 and the mounting groove 2 of the bracket 21.

[0028] like Figure 4 As shown, the two three-jaw chucks 03 are respectively rotatably installed in the two mounting slots 1 of bracket 4 21 and bracket 5 27;

[0029] like Figure 5 As shown, the synchronous rotation device 04 includes two gear rings 41, two gears 42, a drive shaft 43, a sliding sleeve 44, two electromagnetic clutches 45, a second reducer 46, and a second motor 47. The two gear rings 41 are fixedly mounted on the sides of two three-jaw chucks 03. The two gears 42 are rotatably mounted on brackets 21 and 27, respectively, with both brackets 21 and 27 located between the two gears 42. A limiting protrusion is provided on the gear 42 on bracket 27. The drive shaft 43 is rotatably mounted in the mounting groove 2 of bracket 21. The portion of the drive shaft 43 near bracket 27 has a size matching the limiting protrusion of bracket 27. The limit groove is provided, and the gear 42 on the drive shaft 43 and the bracket 27 slides together. The sliding sleeve 44 is rotatably installed in the mounting groove 3 of the bracket 27, and the sliding sleeve 44 is provided with the same limit protrusion.

The motor 2 47 is fixedly installed on the reducer 2 46, and the motor 2 47 provides power to the drive shaft 43 through the reducer 2 46.

[0030] like Figure 6 and Figure 7As shown, the detection device 05 includes a bracket 6 51, a bracket 7 52, a laser receiver 53 and a laser emitter 54. The bracket 6 51 and the bracket 7 52 are both installed on the top of the base plate 12, and the bracket 6 51 and the bracket 7 52 are located on the left and right sides of the bracket 4 21 respectively. The laser receiver 53 is installed on the top of the bracket 6 51 and the laser emitter 54 is installed on the top of the bracket 7 52.

[0031] First, the steel structure is fixed in two three-jaw chucks 03. The three-jaw chucks 03 clamp and fix the steel structure in a centered manner. Then, the three-jaw chucks 03 are rotated to align the angles of the steel structures on both sides. The electromagnetic clutch 45 can disconnect the power transmission from the drive shaft 43, making it easier for workers to adjust the angle difference between the two steel structures and improve the docking effect. Then, motor 1 25 is turned on, and motor 1 25 provides power. The power is transmitted through reducer 1 24, lead screw 22, optical rod 23 and slider 26, driving bracket 5 27 to move closer to or away from bracket 4 21. When bracket 5 27 moves closer to bracket 4 21, it causes the steel structure to press against it. At the same time, the laser is turned on. Receiver 53 and laser emitter 54 emit laser light, and laser receiver 53 receives the laser light. The laser receiver 53 and laser emitter 54 work together to perform laser irradiation inspection on the steel structure to ensure that there are no gaps at the joints of the steel structure and improve the docking effect. After the steel structure is tightened, motor 2 47 is turned on. Motor 2 47 provides power, which is transmitted through drive shaft 43, gear 42 and gear ring 41 to drive the three-jaw chuck 03 to rotate the steel structure synchronously, thereby facilitating the welding of the steel structure by the workers. The sliding fit of drive shaft 43 and gear 42 facilitates the transmission of power when the support 5 27 is in different positions.

[0032] Example 2

[0033] In addition to Example 1, it also includes:

[0034] like Figure 8 As shown, the supporting device 06 includes two hydraulic cylinders 61 and a support plate 62. The two hydraulic cylinders 61 are both installed on the top of the base plate 12, and the support plate 62 is installed on the top of the two hydraulic cylinders 61.

[0035] First, the steel structure is fixed in two three-jaw chucks 03. The three-jaw chucks 03 center and clamp the steel structure. Then, the hydraulic cylinder 61 is opened, providing power to drive the support plate 62 to move up and down. The support plate 62 moves upward to support the far end of the steel structure, preventing it from tilting due to gravity. Afterward, the three-jaw chucks 03 are rotated to align the angles of the two steel structures. The electromagnetic clutch 45 disconnects the power transmission from the drive shaft 43, making it easier for workers to adjust the angle difference between the two steel structures and improve the docking effect. Then, the motor 25 is opened, providing power. The power is transmitted through the reducer 24, lead screw 22, guide rod 23, and slider 26, driving the bracket 27 to move closer to or away from the bracket 21. When bracket 527 approaches bracket 421, it causes the steel structure to tighten. Simultaneously, laser receiver 53 and laser emitter 54 are activated. Laser emitter 54 emits laser light, and laser receiver 53 receives the laser light. Laser receiver 53 and laser emitter 54 work together to perform laser irradiation detection on the steel structure, ensuring that there are no gaps at the joints of the steel structure and improving the docking effect. After the steel structure is tightened, motor 247 is activated. Motor 247 provides power, which is transmitted through drive shaft 43, gear 42 and gear ring 41, driving three-jaw chuck 03 to rotate the steel structure synchronously. This facilitates welding of the steel structure by workers. The sliding engagement of drive shaft 43 and gear 42 facilitates power transmission when bracket 527 is in different positions.

[0036] like Figures 1 to 8As shown, this utility model discloses a quick-connection device for welding steel structural components. During operation, the steel structure is first fixed in two three-jaw chucks 03, which center and clamp the steel structure. Then, the hydraulic cylinder 61 is activated, providing power to drive the support plate 62 to move up and down. The support plate 62 moves upward to support the far end of the steel structure, preventing it from tilting due to gravity. Next, the three-jaw chucks 03 are rotated to align the angles of the two steel structures. The electromagnetic clutch 45 disconnects the power transmission from the drive shaft 43, allowing workers to easily adjust the angle difference between the two steel structures and improve the connection effect. Finally, the motor 25 is activated, providing power through the reducer 24, lead screw 22, guide rod 23, and slider 26, driving... Support 5 27 moves closer to or further away from support 4 21. When support 5 27 moves closer to support 4 21, it causes the steel structure to be pressed against it. At the same time, the laser receiver 53 and the laser emitter 54 are turned on. The laser emitter 54 emits a laser, and the laser receiver 53 receives the laser. The laser receiver 53 and the laser emitter 54 work together to perform laser irradiation detection on the steel structure to ensure that there are no gaps at the joint of the steel structure and improve the docking effect. After the steel structure is pressed against it, the motor 2 47 is turned on. The motor 2 47 provides power. The power is transmitted through the transmission shaft 43, gear 42 and gear ring 41 to drive the three-jaw chuck 03 to drive the steel structure to rotate synchronously, which facilitates the worker to weld the steel structure. The slidingly fitted transmission shaft 43 and gear 42 facilitate the transmission of power when support 5 27 is in different positions.

[0037] The lead screw 22, motor 1 25, two three-jaw chucks 03, two gear rings 41, two gears 42, two electromagnetic clutches 45, motor 2 47, laser receiver 53, laser emitter 54, and two hydraulic cylinders 61 of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0038] The main functions achieved by this utility model are as follows: by setting a three-jaw chuck 03, the steel structure is centered and clamped to prevent the steel structure from tilting and creating gaps, thereby improving the welding quality. Furthermore, by setting a synchronous rotation device 04, the steel structure is driven to rotate synchronously on both sides, reducing the torque on the welding position of the steel structure, preventing the steel structure from breaking during welding, and improving the welding effect. This solves the existing technical problems that existing machines easily cause the steel structure to tilt when clamping, resulting in large gaps at the interface of the steel structure and poor welding quality. In addition, existing machines only drive the steel structure to rotate on one side, which easily causes the steel structure to break during rotational welding, resulting in poor welding effect.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
