[0002] Drilling of offshore wind turbine flanges is a crucial step in the production process. The main purpose is to ensure the precise docking of flange connection parts, thereby ensuring the connection stability between the flange and other parts such as towers and blades. The drilling process requires high-precision drilling devices to complete. These devices usually include CNC drilling machines, hydraulic drilling machines, etc., which can adjust the drill type and drilling depth according to different needs. The structure of the drilling device usually consists of a drive system, a drill system, a positioning system and a control system. The drive system provides sufficient power to ensure that the drill can penetrate the flange material smoothly; the drill system selects the appropriate drill according to the material to ensure smooth drilling; the positioning system ensures the accuracy of drilling, and common positioning methods include mechanical positioning and laser positioning; the control system is used to accurately control various parameters in the drilling process to improve the level of automation and accuracy; As disclosed in the authorization announcement number CN118989398B, an automated drilling device for wind power flange production includes a tooling table; a fixed bracket; a dustproof multi-element drilling unit, which is arranged between the fixed bracket and the tooling table and connected to the fixed bracket; a positioning support unit, which is connected to the tooling table; an air guide and dust collection unit, which is connected to the tooling table and to the dustproof multi-element drilling unit; wherein the dustproof multi-element drilling unit includes: a multi-unit synchronous perforating component, a spacing control component and an isolation and protection component. By setting up the dustproof multi-element drilling unit, the drilling of the wind power flange can be completed at one time, and the debris can be blocked and recovered during drilling. The existing drilling technology and device operation method of offshore wind power flanges are basically the same, that is, the flange needs to be fixed on the drilling equipment to ensure accurate position without any scratches. deviation; then the drill bit starts and starts drilling under the guidance of the control system; finally, after the drilling is completed, the equipment will automatically exit and perform a quality inspection. However, when the above technical solution uses multiple dust-proof multi-element drilling units to perform multi-point synchronous drilling, each drilling unit requires a drive motor to drive it, and each spacing control component also requires a motor to drive it.
