Description

Technical Field

[0001] This utility model belongs to the field of wind turbine assembly technology, and specifically relates to a CNC semi-automatic wind turbine assembly machine. Background Technology

[0002] The CNC semi-automatic wind turbine assembly machine is a specialized wind turbine assembly equipment that integrates CNC technology with semi-automatic operation. Its core functionality involves precise control of key processes through a CNC system, such as the angle positioning of the rotating mold and the pressure control of the pressing device, while retaining some manual assistance, forming a "precise machine control + flexible human cooperation" operation mode. The machine frame is welded from high-strength carbon steel and treated with rust-proof paint to ensure structural stability and long-term durability. During operation, workers place components such as the wind turbine end rings and blades into customized fixtures. The CNC system drives the rotating mold to rotate according to preset parameters, while the unloading device simultaneously and quickly feeds the blades into designated positions. The pressing mechanism then precisely bends and fixes both ends of the blades. This equipment avoids the high cost and complex maintenance issues of fully automated equipment and improves assembly accuracy through CNC technology, enabling control of key parameters such as wind turbine concentricity and blade spacing to the millimeter level. This significantly improves production efficiency and product qualification rate, making it suitable for mass production of wind power equipment.

[0003] Currently available CNC semi-automatic wind turbine assembly machines suffer from machining and installation errors, resulting in height discrepancies between the placement platform and the mold. The lack of a lifting function prevents dynamic adjustment of this discrepancy, making it difficult for workers to accurately judge component placement height visually, easily leading to inaccurate positioning of wind turbine components and molds. In subsequent pressing processes, key parameters such as blade angle and component spacing deviate from design values, affecting the concentricity and overall quality of the wind turbine, increasing the defect rate. Furthermore, different wind turbine specifications have varying component heights and mold thicknesses. Fixed-height placement platforms cannot meet the production needs of multi-specification wind turbines. When switching production models, manual adjustment of the placement platform height using shims and other auxiliary tools is required, which is cumbersome and unstable. This method also leads to changes in equipment baselines, requiring recalibration of CNC system parameters, increasing changeover time and modification costs, and significantly limiting the equipment's versatility and production flexibility. Utility Model Content

[0004] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a CNC semi-automatic wind turbine assembly machine to solve the problem that due to errors in machining and installation, the relative height between the placement platform and the mold may deviate. The lack of lifting function makes it impossible to dynamically adjust this deviation, and it is difficult for workers to accurately judge the placement height of the parts with the naked eye. This can easily lead to inaccurate positioning of the wind turbine parts and the mold. In the subsequent pressing process, key parameters such as blade angle and part spacing will deviate from the design value, thereby affecting the concentricity and overall quality of the wind turbine and increasing the defect rate.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] This CNC semi-automatic impeller assembly machine includes a worktable. Assembly components, pressing components, and extrusion components are mounted on the top of the worktable. A servo motor is installed inside the top of the worktable, and a divider is installed at the output end of the servo motor. A coupling is rotatably connected to the top of the worktable, and the output end of the divider is fixedly connected to the coupling. A deflector ring is fixedly connected to the top of the coupling, and an impeller fixture is fixedly connected to the top of the deflector ring. A first ejector bracket is fixedly connected to the top of the worktable, and an ejector cylinder is installed on one side of the first ejector bracket. A lifting plate is fixedly connected to the telescopic end of the ejector cylinder, and lifting columns are symmetrically fixedly connected to the top of the lifting plate. The other end of the lifting columns extends out of the top of the worktable and is fixedly connected to a lifting platform. This allows the placement platform to match the reference height of the impeller fixture in real time, ensuring that the component positioning surface and the impeller fixture reference surface remain horizontal. When manually placing the impeller ring, there is no need to visually judge the height difference; precise alignment can be achieved simply by directly fitting it to the placement platform, significantly improving the impeller's pass rate. Furthermore, for different impeller models, the placement platform height can be adjusted with one click via the operation panel, without the need for shims or frame modifications.

[0007] As a preferred technical solution, the assembly components include a hopper base plate, a hopper slider, a hopper moving plate, a hopper cylinder, and an insert blade module. The hopper base plate is fixedly connected to the top of the worktable. The hopper slider is symmetrically slidably connected to the top of the hopper base plate.

The hopper cylinder is installed on one side of the hopper base plate. The telescopic end of the hopper cylinder extends into the hopper base plate and is fixedly connected to the hopper moving plate. The hopper guide rail is symmetrically fixedly connected to the top of the hopper base plate. A hopper guide groove is opened at the bottom of the hopper slider. The hopper guide rail and the hopper guide groove are slidably connected, which can realize the precise lateral movement of the insert blade module. The hopper guide groove and the hopper guide rail work together to ensure the smoothness of the movement and avoid shaking. Moreover, the symmetrical structure design improves the load balance and allows for flexible adjustment of the robotic arm's working position to adapt to the assembly requirements of different specifications of impellers, making the insertion action more efficient and precise, and enhancing the practicality and flexibility of the equipment.

[0008] As a preferred technical solution, the pressing assembly includes a pressing cylinder, a top cover side plate, a side plate slider, a top cover pressure plate, and a top cover. The pressing cylinder is installed at the top of the workbench. The top cover side plate is fixedly connected to the top of the workbench. A side plate slider is symmetrically slidably connected to one side of the top cover side plate, and the top cover pressure plate is fixedly connected to the other side of the side plate slider. A top cover is installed on one side of the top cover pressure plate. The telescopic end of the pressing cylinder extends out of the top of the workbench and is fixedly connected to the top cover pressure plate. A side plate guide rail is symmetrically fixedly connected to one side of the top cover side plate. A side plate guide groove is symmetrically opened on one side of the side plate slider. The side plate guide rail and the side plate guide groove are slidably connected, enabling precise lifting and lowering of the top cover. The cooperation between the side plate guide groove and the side plate guide rail ensures vertical movement without deviation, guaranteeing uniform pressing force. Simultaneously, the symmetrical structure enhances stability and allows for flexible adjustment of the pressing position and force, adapting to the pressing requirements of different specifications of wind turbine components, making the pressing action more efficient and precise, and improving the quality and reliability of wind turbine assembly.

[0009] As a preferred technical solution, the extrusion assembly includes an extrusion slide, an extrusion cylinder, an extrusion bracket, an extrusion wheel, and an extrusion slider.

An extrusion guide rail is fixedly connected to one side of the extrusion bracket. The extrusion guide rail and the extrusion guide groove are slidably connected, which can correct assembly deviations such as end ring offset and blade angle in real time. This ensures the coaxiality of the end ring and hub, and the accuracy of the blade angle, avoiding assembly skewing problems caused by positioning errors. It significantly improves the accuracy of key dimensions such as the coaxiality of the wind turbine and the blade spacing. It can adapt to different specifications of wind turbines, quickly switch production models, reduce manual adjustment procedures, and improve production efficiency.

[0010] As a preferred technical solution, an operation control box is installed on the top of the workbench, and a system display is also installed on the top of the workbench. Through the operation control box, workers can quickly start and stop the equipment and adjust parameters, which improves the efficiency of human-machine interaction. Through the system display, information such as assembly progress, equipment status, and parameter data can be displayed in real time. Workers do not need to frequently switch interfaces or view from a distance. They can intuitively grasp the production situation, detect abnormalities in time, and make adjustments.

It can be directly attached to the platform to achieve precise alignment, which significantly improves the pass rate of the impeller. Moreover, for different models of impellers, the height of the platform can be adjusted with one click through the operation panel without the need to add shims or modify the frame.

The surface of the extrusion wheel is in contact with the surface of the blade. At the same time, the extrusion bracket drives the extrusion guide rail to slide and limit within the extrusion guide groove of the extrusion slider. Then, the servo motor is activated, which drives the coupling to rotate through the divider. The coupling drives the wind turbine ring and the wind turbine fixture to rotate.
