Description

Technical Field

[0001] This utility model belongs to the field of thermal spraying technology, and in particular relates to a suspension bracket for thermal spraying. Background Technology

[0002] Thermal spraying, a core process in modern industrial surface treatment, involves heating materials to a molten or semi-molten state and depositing them onto a substrate surface via high-speed spraying to form a coating with specific functions. This technology overcomes the limitations of traditional material properties, demonstrating unique value in areas such as extreme environment protection, mechanical performance enhancement, and resource recycling. The core advantages of thermal spraying technology lie in its material adaptability and process flexibility. It covers almost all engineering material systems, from metal alloys to ceramic powders, from polymers to composite materials. For example, yttrium-stabilized zirconia thermal barrier coatings prepared using plasma spraying on aero-engine turbine blades can reduce the temperature of the substrate metal by more than 300°C, significantly extending the component's lifespan. In the remanufacturing field, arc spraying technology can restore the dimensional accuracy of worn shaft parts at extremely low cost, improving economic efficiency by more than 40% compared to traditional electroplating processes. To ensure the comprehensiveness of the thermal spraying process, parts are typically suspended during the process.

[0003] Comparing this to Chinese patent CN221619821U, which discloses a suspension bracket for thermal spraying, the invention includes a sliding plate, a bracket, and a movable frame. The sliding plate is movably connected inside the movable frame, and the bracket is fixedly connected to both sides of the bottom of the movable frame. Several sliding plates are evenly distributed, and a fixed rod is fixedly connected to the bottom of each sliding plate. A movable sleeve is fixedly connected to the bottom surface of the fixed rod, and a rotating disk is movably connected inside the movable sleeve. By incorporating the rotating disk, the rotation of the rotating disk drives the mounting block to rotate via the rotating rod, thereby causing the suspension bracket to rotate. This solves the problem that existing suspension brackets lack a self-rotating structure for rotating and spraying workpieces, requiring manual rotation of the workpiece for comprehensive spraying. This not only necessitates manual rotation of the suspension bracket to drive the workpiece for spraying but also reduces the efficiency of the user's workpiece spraying, presenting certain limitations.

[0004] However, the aforementioned patent is fixed in place and requires manual handling of parts for suspension, which increases labor intensity and slows down the continuous thermal spraying speed. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a suspension bracket for thermal spraying to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A suspension bracket for thermal spraying includes a hook assembly for suspending parts and a traveling assembly for supporting movement. An adjustment assembly for lifting, raising, and circumferentially rotating to adjust the thermal spraying position is installed in the middle of the traveling assembly. The hook assembly is mounted on the adjustment assembly. The traveling assembly includes two symmetrically arranged traveling bases, each with two symmetrically mounted traveling wheels. At least one traveling wheel on each traveling base is equipped with a traveling motor. A gantry frame is arranged between the tops of the two traveling bases. The adjustment assembly includes a lifting mechanism for vertical movement, with a rotating mechanism providing circumferential rotational power installed in the middle of the lifting mechanism. The hook assembly includes a suspension frame with a connecting seat, and two hook mechanisms symmetrically mounted at both ends of the suspension frame.

[0008] Furthermore, control boxes and batteries are symmetrically installed on both sides of the gantry frame.

[0015] 1. The walking assembly (motor-driven walking wheels + gantry) supports the rapid positioning of the overall support frame, and the lifting mechanism (linear motor + guide rail) can accurately adjust the height of parts. Combined with the walking assembly, it enables multi-angle spraying, further optimizes the coating distribution, adapts to the spraying needs of different workstations, and reduces manual handling time.

[0016] 2. The suspended parts are driven to rotate circumferentially by a rotating mechanism (servo motor + gear transmission), so that the spraying material can be evenly covered on the surface of the parts, avoiding the problem of uneven coating thickness caused by traditional fixed suspension; the lifting and rotating mechanisms are operated in coordination by an electronic control system (control box + battery), eliminating the need for manual adjustment and significantly shortening the process changeover time;

[0017] 3. The U-shaped groove and locking nut structure of the hook assembly allows for quick assembly and disassembly of the hook body, adapting to parts of different shapes and sizes and expanding application scenarios; the U-shaped groove and locking nut structure of the hook assembly allows for quick assembly and disassembly of the hook body, adapting to parts of different shapes and sizes and expanding application scenarios;

[0018] 4. Automated control (motor-driven movement, lifting, and rotation) reduces manual intervention and the risk of operational errors, making it especially suitable for handling heavy or high-temperature parts; through mechatronics design, it solves the problems of poor uniformity, low efficiency, and insufficient adaptability in traditional thermal spraying, combining functionality, flexibility, and reliability, and significantly improving spraying quality and production efficiency.
