Description

Technical Field

[0001] This utility model relates to the technical field of welding positioning mechanisms, specifically a welding positioning mechanism for precast steel mesh. Background Technology

[0002] Reinforcing mesh is a mesh in which longitudinal and transverse bars are arranged at certain intervals and perpendicular to each other, with all intersections welded together. Reinforcing mesh can significantly improve the quality and construction speed of reinforced concrete projects and enhance its crack resistance, offering good overall economic benefits. However, the positioning of the transverse and longitudinal bars before welding has always been a problem to be solved in the production process of reinforcing mesh. Traditional positioning methods often rely on manual operation, using steel wire for multiple fixing points, which is not only inefficient but also difficult to guarantee positioning accuracy, leading to unstable welding quality and affecting the overall performance of the reinforcing mesh. Therefore, there is an urgent need to design a welding positioning mechanism that can quickly and accurately position the transverse and longitudinal bars to improve the production efficiency and quality of reinforcing mesh. Utility Model Content

[0003] This utility model mainly provides a welding positioning mechanism for precast steel mesh, which solves the problems of difficulty and low efficiency in positioning transverse and longitudinal bars before welding in the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A precast steel mesh welding and positioning mechanism includes a conveyor with mounting frames symmetrically arranged on both sides. Each mounting frame on each side is equipped with a lateral displacement adjustment component. The output end of each lateral displacement adjustment component has a lateral mounting platform, on which transverse reinforcement end clips are detachably connected. Each mounting frame on each side has symmetrically arranged longitudinal displacement adjustment components at both ends. Each longitudinal displacement adjustment component has a lifting component, with a lifting platform at its upper end. Longitudinal reinforcement end clips are detachably connected to the lifting platform. The conveyor can utilize existing technology, such as a belt conveyor or chain conveyor, as long as it enables the transport of the welded steel mesh. "Setting up" refers to the fact that the components can be connected and fixed using any existing connection method, as long as the overall mechanism remains stable. In practical use, the horizontal reinforcing bars are first placed in the end clips of the horizontal reinforcing bars using an external robotic arm, a corresponding clamping mechanism, or manually. Then, the longitudinal reinforcing bars are placed on the end clips of the longitudinal reinforcing bars. Next, the lifting assembly is activated to lower the lifting platform and the end clips of the longitudinal reinforcing bars, thereby adjusting the height of the longitudinal reinforcing bars so that they overlap the horizontal reinforcing bars. Subsequently, the horizontal and longitudinal reinforcing bars are welded using a corresponding welding machine. After welding, the horizontal adjustment cylinder is activated, which moves the end clips of the horizontal reinforcing bars laterally. At the same time, the vertical adjustment cylinder is activated, which moves the end clips of the longitudinal reinforcing bars longitudinally, thereby causing the welded steel mesh to detach from the positioning mechanism and fall onto the conveyor, which then sends it to the next process. When it is necessary to produce steel mesh of different specifications, simply remove the end clips of the horizontal and longitudinal reinforcing bars from the horizontal mounting platform and the lifting platform, and replace them with clips of the appropriate specifications. This structure, by incorporating lateral displacement adjustment components, longitudinal displacement adjustment components, and lifting components, along with end clamps for transverse and longitudinal reinforcement bars, enables rapid and accurate positioning of the transverse and longitudinal reinforcement bars in the transverse, longitudinal, and height directions. This improves the efficiency and accuracy of welding positioning and allows for shrinkage cutting after welding. The end clamps for transverse and longitudinal reinforcement bars are detachably connected to the transverse mounting platform and lifting platform, facilitating the replacement of appropriate clamps for different specifications of steel mesh, thus enhancing the equipment's versatility and applicability.

[0006] Furthermore, the lateral displacement adjustment assembly includes a lateral adjustment electric cylinder mounted on the mounting frame and a limiting guide slidably connected to the mounting frame; the lateral mounting platform is fixedly connected to the output end of the lateral adjustment electric cylinder, and the lateral mounting platform is fixedly connected to the inner end of the limiting guide. With this structure, the lateral adjustment electric cylinder can precisely control the displacement of the lateral mounting platform, while the limiting guide plays a guiding and limiting role in the movement of the lateral mounting platform, ensuring the stability of the end clamps of the transverse ribs, and facilitating the subsequent displacement of the lateral mounting platform via the lateral adjustment electric cylinder.

[0007] Furthermore, the longitudinal displacement adjustment assembly includes a horizontal frame detachably connected to the mounting bracket, a longitudinal adjustment electric cylinder disposed on the horizontal frame, and a longitudinal mounting platform disposed at the output end of the longitudinal adjustment electric cylinder; the lifting assembly is disposed on the longitudinal mounting platform. With this structure, the position of the longitudinal mounting platform can be adjusted by the longitudinal adjustment electric cylinder, thereby supporting the longitudinal rib when extended and allowing the longitudinal rib to fall off when retracted.

[0008] Furthermore, the lifting assembly includes a lifting electric cylinder mounted on the longitudinal mounting platform and a lifting guide rod mounted on the longitudinal mounting platform; the lifting platform is fixedly connected to the output end of the lifting electric cylinder, and the lifting platform is fixedly connected to the upper end of the lifting guide rod. With this structure, the lifting electric cylinder can drive the lifting platform to move up and down, and the lifting guide rod guides the lifting process of the lifting platform, ensuring that the end clamps of the longitudinal ribs can accurately adjust the height position of the longitudinal ribs.

[0009] Furthermore, the upper surface of the longitudinal mounting platform is lower than the conveying surface of the conveyor. This structure, where the upper surface of the longitudinal mounting platform is lower than the conveying surface of the conveyor, allows the welded steel mesh to easily detach from the positioning mechanism and fall onto the conveyor. It also prevents the longitudinal mounting platform from affecting the displacement of the steel mesh, facilitating subsequent processes and further improving production efficiency.

[0010] Furthermore, the lower ends of both the transverse and longitudinal reinforcement end clips are provided with multiple inserts, and the transverse mounting platform and lifting platform are provided with insertion holes to accommodate these inserts. This detachable connection method facilitates the replacement of the corresponding transverse and longitudinal reinforcement end clips according to different specifications of steel mesh, improving the versatility and flexibility of the equipment.

[0011] Beneficial effects: By setting up lateral displacement adjustment components, longitudinal displacement adjustment components, and lifting components, in conjunction with transverse and longitudinal rib end clamps, rapid and accurate positioning of transverse and longitudinal ribs in the transverse, longitudinal, and height directions can be achieved, improving the efficiency and accuracy of welding positioning, and enabling shrinkage cutting after welding; the transverse and longitudinal rib end clamps are detachably connected to the transverse mounting platform and lifting platform, facilitating the replacement of corresponding clamps according to different specifications of steel mesh, improving the versatility and applicability of the equipment; the upper surface of the longitudinal mounting platform is lower than the conveying surface of the conveyor, allowing the welded steel mesh to smoothly detach from the positioning mechanism and fall onto the conveyor, and preventing the longitudinal mounting platform from affecting the displacement of the steel mesh, facilitating subsequent processes and further improving production efficiency; Attached Figure Description
