Description

Technical Field

[0001] This utility model relates to the field of longitudinal beam assembly processing technology, and in particular to a longitudinal beam assembly flipping and welding device. Background Technology

[0002] In the automotive manufacturing industry, the chassis, as the core structure that bears the weight of the entire vehicle and transmits various loads, is of paramount importance. The longitudinal beams of the chassis are the backbone of the entire chassis, bearing the main stress during vehicle operation. Their structural design and manufacturing process are directly related to the safety and reliability of the vehicle. Taking semi-trailers as an example, their longitudinal beam cross-section structure usually adopts the form of I-beams. Although this structure has good load-bearing capacity and stability, the connection between the upper and lower flanges and the web plate requires welding on both sides, which brings considerable challenges to the welding process.

[0003] Because the longitudinal beams of semi-trailers are quite long, reaching up to thirteen meters, and welding on both sides requires flipping the longitudinal beams, ordinary welding equipment often cannot meet the requirements for flipping the longitudinal beams. Using conventional methods to flip the longitudinal beams is not only complicated to operate, but also prone to deformation or damage due to improper operation, which in turn affects the welding quality and vehicle performance.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1-5 As shown, this utility model embodiment provides a longitudinal beam assembly flipping and welding device, including a base 1, with multiple support frames 2 fixedly connected at equal intervals on the upper end of the base 1, and I-beams 3 provided on the upper end of the support frames 2. Limiting grooves 11 are formed on the upper end surfaces of the left and right sides of the base 1; it also includes,

[0027] The fixed flipping mechanism 4 is set inside the limiting grooves 11 on the left and right sides of the I-beam 3. The fixed flipping mechanism 4 is used to continue the flipping operation of the I-beam 3.

[0028] The drive mechanism 5 is located inside the base 1 and provides power to the fixed flipping mechanism 4 to achieve the functions of fixing and disassembling the I-beam 3. During operation, the height of the connecting seat 43 is adjusted by the extension and retraction of the hydraulic cylinder 47, and then the drive mechanism 5 drives the bidirectional threaded rod 51 to rotate, so that the slider 41 moves horizontally in the limiting groove 11, thereby driving the fixed flipping mechanism 4 to move closer to or away from the I-beam 3. When the fixed flipping mechanism 4 contacts the I-beam 3, the I-beam groove 451 on the fixing block 45 fits tightly with the end of the I-beam 3, thereby fixing the I-beam 3. Subsequently, the first motor 48 starts and drives the rotating shaft 44 to rotate through the timing pulley assembly 462, thereby causing the fixing block 45 to rotate around the rotating shaft 44, completing the flipping operation of the I-beam 3.

[0029] In a further embodiment, refer to Figures 2-4 The fixed flipping mechanism 4 includes a slider 41 and a connecting seat 43. The slider 41 is slidably connected inside the limiting groove 11. A limiting rod 42 is fixedly connected to the upper end of the slider 41. The connecting seat 43 is slidably connected to the side wall of the limiting rod 42. A rotating shaft 44 is rotatably connected inside the connecting seat 43. A fixing block 45 is fixedly connected to the end of the rotating shaft 44 near the I-beam 3. An I-beam groove 451 is opened on the end face of the fixing block 45 near the I-beam 3. Both ends of the I-beam 3 are embedded in the I-beam groove 451. A protrusion 452 is fixedly connected to the end of the fixing block 45 away from the rotating shaft 44. A chamfer 453 is provided on the end of the protrusion 452 near the I-beam 3. A first motor 48 is fixedly connected to the right end of the connecting seat 43 located on the right side of the base 1. The output shaft end of the first motor 48 is fixedly connected to the right end of the rotating shaft 44. A hydraulic cylinder 47 is fixedly connected to the upper end of the slider 41. The output shaft end of the hydraulic rod is fixedly connected to the lower end of the connecting seat 43.

[0030] In this embodiment, the combined design of slider 41, limiting rod 42, connecting seat 43, rotating shaft 44, fixing block 45, and hydraulic cylinder 47 achieves stable fixing and efficient flipping of the I-beam 3. The sliding connection of slider 41 in the limiting groove 11 ensures the horizontal movement accuracy of the fixing and flipping mechanism 4, while the limiting rod 42 provides stable vertical guidance for the connecting seat 43. The fitting design of the I-beam groove 451 on the fixing block 45 with the I-beam 3 can closely fit the shape of the I-beam 3, ensuring that it will not slide or shift during the flipping process. The design of the protrusion 452 and the chamfer 453 facilitates the rapid positioning and assembly of the I-beam 3, further improving the operating efficiency. The extension and retraction action of the hydraulic cylinder 47 can flexibly adjust the height of the connecting seat 43 so that the I-beam 3 can be embedded in the I-beam groove 451. At the same time, the first motor 48 drives the fixing block 45 to rotate through the rotating shaft 44, realizing the precise flipping of the I-beam 3. This structural design not only improves the automation level of the welding device, but also significantly improves the efficiency and quality of longitudinal beam welding.

[0031] In a further embodiment, refer to Figures 4-5 The fixed flipping mechanism 4 also includes a connecting component 46, which includes a connecting shaft 461 and a connecting rod 463. The connecting rod 463 is rotatably connected to the rear end of the connecting seat 43 located on the left side of the base 1 via a bearing seat. The connecting shaft 461 is fixedly rotatably connected to the rear end of the connecting seat 43 located on the right side of the base 1 via a bearing seat. The right end of the connecting rod 463 passes through the interior of the connecting shaft 461 and is slidably connected to it. The side walls of the connecting rod 463 and the connecting shaft 461 are both connected to the rotating shaft 44 via a timing pulley assembly 462.

[0032] In this embodiment, by introducing a connecting component 46, including a connecting shaft 461 and a connecting rod 463, and combining it with the transmission connection method of the timing pulley assembly 462, the structure and function of the longitudinal beam assembly flipping welding device are further optimized. The sliding connection design between the connecting rod 463 and the connecting shaft 461 ensures that the fixed flipping mechanisms 4 on both sides can maintain synchronous movement during the flipping process, thereby avoiding the twisting or deformation of the I-beam 3 caused by inconsistent movements on both sides. The transmission connection of the timing pulley assembly 462 ensures the precise rotation of the rotating shaft 44, so that the I-beam 3 can smoothly and evenly complete the angle adjustment during the flipping process. This not only improves the reliability and stability of the device, but also significantly improves the positioning accuracy and flipping efficiency of the I-beam 3 during the welding process, further enhancing the practicality and adaptability of the device.

[0033] In a further embodiment, refer to Figure 2The drive mechanism 5 includes a bidirectional threaded rod 51 and a second motor 52. The bidirectional threaded rod 51 is rotatably connected inside the base 1. The left and right sides of the bidirectional threaded rod 51 pass through the slider 41 and are threadedly connected to it. The second motor 52 is fixedly connected to the right end of the base 1, and the output shaft end of the second motor 52 is fixedly connected to the right end of the bidirectional threaded rod 51.

[0034] In this embodiment, a drive mechanism 5 consisting of a bidirectional threaded rod 51 and a second motor 52 is used to achieve efficient driving and precise control of the fixed flipping mechanism 4. The left and right sides of the bidirectional threaded rod 51 are threadedly connected to the sliders 41 respectively. When the second motor 52 is started, its output shaft drives the bidirectional threaded rod 51 to rotate, thereby driving the sliders 41 on both sides to move synchronously towards or away from each other along the limiting groove 11. This not only enables rapid adjustment of the distance between the fixed flipping mechanism 4 and the I-beam 3, realizing rapid clamping or loosening of the I-beam 3, but also ensures the consistency of the actions on both sides, avoiding tilting or damage to the I-beam 3 due to uneven force on one side. In addition, the transmission method of the bidirectional threaded rod 51 has high transmission accuracy and stability, which can effectively improve the automation level and operating efficiency of the device, further enhancing the reliability and practicality of the device in the longitudinal beam welding process.

[0035] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
