Description

Technical Field

[0001] This utility model relates to a displacement mechanism for steel structure welding, belonging to the technical field of steel structure welding processing. Background Technology

[0002] Currently, during the welding process of steel structures, due to the numerous welding locations, it is often necessary to flip or move the steel structure to expose the areas requiring welding. However, steel structures are generally heavy and long, making flipping or repositioning inconvenient. Therefore, appropriate displacement mechanisms are often required to perform these tasks.

[0003] To address this, in the prior art, Chinese patent application publication number CN112809290A discloses a displacement device suitable for steel structure welding, including a bracket and a rotating disk rotatably mounted on the bracket. The rotating disk has a first mounting groove for mounting the steel structure, and a clamping assembly for fixing the steel structure is movably mounted on the rotating disk. This solution installs the steel structure through the first mounting groove and clamps it with the clamping assembly, thus mounting the steel structure onto the rotating disk. The rotation of the rotating disk then drives the steel structure to change position, facilitating welding of the steel structure by external manual or robotic welding systems. However, this solution has the following problems: it requires multiple gear structures to drive the rotating disk to ensure stability during movement. However, each gear pair generates friction loss during meshing, and the cumulative friction loss increases with the energy transmission of multiple gears, reducing overall transmission efficiency. Furthermore, in multi-gear systems, the wear and lubrication requirements between gears are higher, resulting in relatively high maintenance and repair costs. Moreover, any problem with any gear will affect the operation of the entire system. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, this utility model provides a displacement mechanism for steel structure welding.

[0005] The technical solution of this utility model is as follows:

[0006] A positioning mechanism for steel structure welding includes a positioner mounting rail, a positioner body mounted on the mounting rail, and a fixed seat mounted on the fixed seat. A gear ring is movably mounted on the fixed seat, and a drive gear is disposed inside the fixed seat, meshing with the gear ring. A sliding groove is formed on the side wall of the gear ring, and the arrangement of the sliding groove is adapted to the structure of the gear ring. Multiple support wheels are rotatably connected inside the fixed seat, and each support wheel is slidably connected in the sliding groove. The gear ring has a placement groove for placing steel structural components and a first mounting component for installing the steel structural components.

[0007] The first mounting component includes a limiting rod, which is installed on the gear ring by means of screws and is positioned to span the placement groove. A threaded clamping rod is threadedly connected to the limiting rod and is positioned to pass through the limiting rod. A rotating handle is provided at the top of the threaded clamping rod.

[0008] The fixed base is provided with a second mounting assembly for installing steel structural components. The second mounting assembly includes symmetrically arranged mounting blocks, a lead screw between the two mounting blocks, and symmetrically arranged sliding blocks threaded onto the lead screw. The two sliding blocks can slide along the lead screw when the lead screw rotates, and the sliding directions are opposite. Each of the two sliding blocks is provided with a clamping block, and the horizontal height of the clamping blocks on both sides is set to enter the placement groove. One of the mounting blocks is also provided with a drive assembly for driving the lead screw to rotate.

[0009] The fixed base is also equipped with a drive motor, which is connected to the drive gear transmission.

[0010] The fixed base is also rotatably connected to multiple lateral limiting wheels. The lateral limiting wheels are arranged in a vertical direction and their wheel walls abut against the side walls of the gear ring.

[0011] One side of the positioner mounting track is also equipped with a robot walking track, on which a robot welding system for welding steel structural components is installed.

[0012] This utility model has the following beneficial effects:

[0013] This invention, through the arrangement of a fixed base, a gear ring, a drive gear, a sliding groove, and support wheels, allows the drive gear to rotate when it meshes with the gear ring. During this process, multiple support wheels rotate within the sliding groove and slide relative to it, providing support for the movement of the gear ring and ensuring its stability during rotation. Compared to existing technologies, this invention eliminates the need for multiple gear structures; only a single drive gear is required. The support wheels, combined with the sliding groove, can replace other gear structures to ensure the stability of the gear ring's rotation. This design offers advantages such as improved transmission efficiency, reduced maintenance costs, and enhanced operational reliability. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example: Please refer to Figures 1-5This embodiment provides a positioning mechanism for steel structure welding, including a positioner mounting rail 1. Several positioner bodies 2 are mounted on the positioner mounting rail 1. The specific number and position of the positioner bodies 2 mounted on the positioner mounting rail 1 can be determined according to the length of the steel structure component 8 to be processed, and are not specifically limited here. Each positioner body 2 includes a fixed base 3, which is mounted on the positioner mounting rail 1. A gear ring 4 is movably mounted on the fixed base 3. A drive gear 5 is disposed inside the fixed base 3, meshing with the gear ring 4. A drive motor 18 is also disposed on the fixed base 3, and is connected to the drive gear 5 in a transmission manner. After the drive motor 18 starts working, it can drive the drive gear 5 to rotate, which in turn drives the gear ring 4 to rotate on the fixed base 3.

[0023] To ensure the stability of the gear ring 4 when rotating on the fixed base 3, in this embodiment, grooves 6 are provided on both the front and rear side walls of the gear ring 4. The arrangement of the grooves 6 on both sides is adapted to the structure of the gear ring 4. Multiple support wheels 7 are rotatably connected inside the fixed base 3. The number of support wheels 7 can be determined according to actual conditions, such as the size of the gear ring 4 and the required load-bearing capacity, and is not limited here. At the same time, the support wheels 7 are symmetrically arranged front and rear within the fixed base 3, with the gear ring 4 located between the two support wheels 7. Each support wheel 7 on each side is slidably connected to the groove 6 on the corresponding side. Through the aforementioned arrangement, when the gear ring 4 rotates under the action of the drive gear 5, the support wheels 7 on both sides rotate within the grooves 6 on the corresponding sides and slide relative to the grooves 6, which can provide support for the movement of the gear ring 4, avoid wobbling during the rotation of the gear ring 4, and thus ensure the stability of the gear ring 4 during rotation.

[0024] The gear ring 4 is also provided with a placement groove 9 for placing the steel structural component 8 and a first mounting assembly for installing the steel structural component 8. In this embodiment, the first mounting assembly includes a limiting rod 10, which is installed on the gear ring 4 by means of screws and is arranged to span across the placement groove 9. A threaded clamping rod 11 is threadedly connected to the limiting rod 10 and is arranged to pass through the limiting rod 10. A rotating handle 12 is provided at the top of the threaded clamping rod 11. With the aforementioned setup, when installing the steel structure component 8, the limiting rod 10 is removed, and then the steel structure component 8 is placed into the placement groove 9. The limiting rod 10 is then installed onto the gear ring 4 using screws. The threaded clamping rod 11 is then rotated using the handle 12, causing it to move downwards and press against the top of the steel structure component 8. This completes the installation of the steel structure component 8, restricting it to the gear ring 4, allowing it to follow the rotation of the gear ring 4.

[0025] To prevent displacement of the steel structural component 8 during welding, in this embodiment, a second mounting assembly for installing the steel structural component 8 is provided on the front side wall of the fixing base 3. The second mounting assembly includes mounting blocks 13 arranged symmetrically on both sides, and a lead screw 14 is provided between the two mounting blocks 13. The lead screw 14 is threadedly connected to sliding blocks 15 arranged symmetrically on both sides. The two sliding blocks 15 can slide along the lead screw 14 when the lead screw 14 rotates, and the sliding directions are opposite. Each of the two sliding blocks 15 is provided with a clamping block 16, and the horizontal height of the clamping blocks 16 on both sides is set to enter the placement groove 9. One of the mounting blocks 13 is also provided with a drive assembly 17 for driving the lead screw 14 to rotate. The drive assembly 17 can be a motor that is connected to the lead screw 14, or a rotating handle that is connected to the lead screw 14. With the aforementioned setup, after the first mounting component limits the steel structure 8, and the steel structure 8 is adjusted to a suitable posture under the action of the gear ring 4, the drive component 17 is used to drive the lead screw 14 to rotate, so that the sliding blocks 15 on both sides move closer to each other, thereby causing the clamping blocks 16 on both sides to move closer to each other. Since the horizontal height of the clamping blocks 16 on both sides is set into the placement groove 9, the side walls of the steel structure 8 that have been limited by the first mounting component can be clamped, thereby preventing the steel structure 8 from shifting during the welding process.

[0026] To further improve the stability of the gear ring 4 when rotating on the fixed base 3, in this embodiment, multiple lateral limiting wheels 19 are rotatably connected inside the fixed base 3. The number of lateral limiting wheels 19 can be determined according to actual conditions and is not limited here. The lateral limiting wheels 19 are arranged symmetrically front and back inside the fixed base 3, and the gear ring 4 is arranged between the two lateral limiting wheels 19. The rotation direction of each lateral limiting wheel 19 is vertical, and the wheel walls of the two lateral limiting wheels 19 abut against the corresponding side walls of the gear ring 4. When the gear ring 4 rotates on the fixed base 3, the two lateral limiting wheels 19 will rotate under the action of friction, providing support for the fixed base 3 without affecting its normal rotation, thereby further improving the stability of the gear ring 4 when rotating on the fixed base 3.

[0027] In this embodiment, during actual use, a robot walking track 20 is also provided on one side of the positioner mounting track 1. A robot welding system 21 for welding steel structural components 8 is installed on the robot walking track 20. The robot welding system 21 can move along the robot walking track 20 to the corresponding position to perform the required welding work. During welding, the steel structural component 8 is placed in the placement slot 9, and then fixed to the gear ring 4 using the first mounting assembly. Afterward, the drive motor 18 is started to drive the drive gear 5 to rotate, causing the gear ring 4 to rotate on the fixed seat 3, thereby adjusting the posture of the steel structural component 8. After adjusting to a suitable posture, the steel structural component 8 is further fixed using the second mounting assembly. Then, the robot welding system 21 is controlled to start working, enabling the corresponding welding work to be performed on the steel structural component 8.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
