Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to a cutting device for irregularly shaped wind turbine flanges. Background Technology

[0002] With the transformation of the global energy structure, wind power generation is developing towards higher power and lighter weight, which places higher demands on the structural performance of wind turbine flanges. In particular, for large offshore wind turbines, in order to optimize load distribution and aerodynamic performance, components such as tower flanges and pitch bearing flanges are increasingly adopting non-circular (such as elliptical, polygonal, or irregular curved surface) irregular designs. However, the manufacturing and processing of such irregular flanges has always been a challenge in the industry.

[0003] Currently, the industry mainly relies on the following methods for cutting and beveling irregular-shaped wind turbine flanges: Manual line drawing combined with simple track cutting: Operators need to manually draw the outline on the surface of the workpiece, and then use a simple magnetic track or guide arm for semi-automatic cutting. This method relies entirely on the worker's experience, has serious positioning errors, resulting in low cutting accuracy, poor cut quality, many burrs and flash, high labor intensity, and extremely low production efficiency, which cannot meet the needs of large-scale production.

[0004] General-purpose CNC machine tool programming and machining: Although it can guarantee accuracy, for the production of small batches and various types of irregular flanges, each time the model is changed, professional programmers need to re-create CAD / CAM models and post-processing. The programming and debugging cycle is long and requires high skills from operators. In addition, large five-axis linkage machining center equipment is expensive, occupies a large area, and has high processing costs, which is not conducive to the flexible production of small and medium-sized enterprises.

[0005] In summary, existing processing technologies for irregularly shaped wind turbine flanges generally lack adaptive compensation and rapid changeover capabilities for irregular contours, making it difficult to adapt to the rapid iteration and flexible manufacturing needs of modern wind power equipment. Therefore, it is particularly urgent to develop an irregularly shaped wind turbine flange cutting device that combines high precision, low cost, ease of operation, and intelligent contouring function. Summary of the Invention

[0006] The purpose of this invention is to provide a cutting device for irregularly shaped wind turbine flanges to solve at least one technical problem existing in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for irregularly shaped wind turbine flanges, comprising a rotatable and adjustable worktable and a three-dimensional moving frame. A quick-change template is provided above the worktable, and a rotating rod is provided at the bottom of the three-dimensional moving frame. A cutting tool is fixedly installed at the bottom of the rotating rod. Multiple sets of clamps are slidably installed on the top surface of the worktable. The cutting device for irregularly shaped wind turbine flanges also includes a contouring component, which can provide radial path guidance for the three-dimensional moving frame according to the shape of the quick-change template. The contouring component also includes an execution unit, which is used to provide specific displacement parameters for path guidance according to the actual proportional relationship between the quick-change template and the product.

[0008] Preferably, a support frame is provided above the workbench, a cylinder is fixedly installed at the bottom of the support frame, a fixing rod is fixedly installed at the output end of the cylinder, a chuck is rotatably connected to the bottom end of the fixing rod through a fixing sleeve, and a fixing tube is slidably installed on the inner ring of the quick-change template.

[0009] Preferably, the contouring component includes a rotating block fixedly installed on the outer wall of a fixed sleeve, sliding blocks rotatably installed on both sides of the outer wall of the rotating block, and sliding pins provided on the outer walls of the two sliding blocks. A sliding cavity is fitted on the outer wall of the fixed sleeve, allowing the sliding blocks to slide within it. Two sets of opposing sliding rods are ball-jointed on the outer wall of the rotating block. The two sets of sliding rods are slidably installed at both ends of the sliding cavity, and springs are provided between the two sets of sliding rods and the two ends of the sliding cavity.

[0010] Preferably, the execution unit includes a slanted rod fixedly installed at the bottom of the sliding plate, a worm gear that can be vertically slidably adjusted in the middle of the worktable, a keyway at the bottom of the fixed tube for the top of the worm gear to be inserted, a fixed rail fixedly installed on the outer wall of the worm gear, a slider slidably installed on the fixed rail, a tension spring between the slider and the end of the fixed rail, a sliding seat fixedly installed at the top of the slider via a support, a roller rotatably installed on the sliding seat that can contact and abut against the outer wall of the quick-change template, and a universal joint rotatably connecting the sliding seat and the slanted rod.

[0011] Preferably, a connecting seat is fixedly installed on the outer wall of the three-dimensional moving frame, and a connecting rod is horizontally slidably installed inside the connecting seat. One end of the connecting rod is rotatably connected to the sliding joint, and the other end of the connecting rod is fixedly connected to the rotating rod.

[0012] Preferably, a rotating shaft is rotatably mounted on the side wall of the workbench, a handwheel is fixedly mounted on one end of the rotating shaft, and a worm wheel that meshes with the worm is fixedly mounted on the other end of the rotating shaft. The outer wall of the worm is connected to the workbench by a thread.

[0013] Preferably, the diagonal rod is inclinedly disposed at the bottom end of the sliding joint, and the angle between the diagonal rod and the sliding joint can be adjusted by a locking device, and the middle connecting rod of the universal joint is connected by a flange.

[0014] Preferably, a displacement sensor is provided at the end of the fixed rail, and a tension sensor is provided on the slider. Both the displacement sensor and the tension sensor are electrically connected to an external control unit. The external control unit is configured to calibrate the radial movement coordinates of the three-dimensional moving frame in real time based on the slider position information fed back by the displacement sensor, and to dynamically adjust the downward driving force of the cylinder based on the feedback value of the tension sensor, so as to ensure that the contact pressure of the roller on the quick-change template is constant.

[0015] Preferably, the inclination angle between the diagonal rod and the bottom end of the sliding joint is set between 45 degrees and 135 degrees.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: I. This invention, through the coordinated operation of quick-change templates and contouring components, combined with the rotation adjustment of the worktable, transforms the complex contour of irregularly shaped wind turbine flanges into proportional displacement parameters that can be recognized by the execution unit. High-precision contour cutting can be achieved without cumbersome CNC programming, significantly shortening the programming and debugging time in small-batch, multi-variety production scenarios. At the same time, it solves the problems of large positioning errors, low efficiency, and poor consistency of traditional manual line drawing and cutting, greatly improving processing accuracy and batch stability.

[0017] Second, this invention constructs a highly sensitive contour following and force control system through the close fit between the roller and the quick-change template, the closed-loop feedback of the displacement sensor and the tension sensor, and the dynamic compensation of the spring and tension spring. It can not only offset the impact caused by the sudden change in the curvature of the template in real time, avoiding tool jamming or overload, but also maintain the constant roller contact pressure by dynamically adjusting the cylinder driving force, ensuring high-fidelity reproduction of the processing trajectory and improving the processing stability and impact resistance of complex irregular flanges.

[0018] Third, this invention, through a handwheel-driven worm gear-worm locking mechanism, a chuck self-centering clamping structure, and an adjustable tilt angle design of the inclined bar, achieves both the rigid synchronous rotation of the quick-change template and the worktable, while also ensuring the convenience of quick template replacement. It adapts to the processing needs of templates of different thicknesses and workpieces of various specifications, ensuring the geometric datum uniformity of the contour trajectory, improving equipment changeover efficiency and operational safety, and achieving a perfect unity of "quick change" and "high-precision synchronization".

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8 This invention provides a technical solution: a cutting device for irregularly shaped wind turbine flanges, including a rotatable and adjustable worktable 1 and a three-dimensional moving frame 3. A quick-change template 20 is provided above the worktable 1, and a rotating rod 5 is provided at the bottom of the three-dimensional moving frame 3. A cutting tool 6 is fixedly installed at the bottom of the rotating rod 5. Multiple sets of clamps 4 are slidably installed on the top surface of the worktable 1. The cutting device for irregularly shaped wind turbine flanges also includes a contouring component, which can provide radial path guidance for the three-dimensional moving frame 3 according to the shape of the quick-change template 20. The contouring component also includes an execution unit, which is used to provide specific displacement parameters for path guidance according to the actual proportional relationship between the quick-change template 20 and the product.

[0023] When using this device, a scaled-down quick-change template 20 is first made according to the product's preset parameters and precisely installed on the top surface of the workbench 1. Then, the irregular wind turbine flange to be processed is placed on the top surface of the workbench 1 and fixed by the clamp 4. The execution unit, in conjunction with the contouring component, collects the contour data of the quick-change template 20 in real time and drives the three-dimensional moving frame 3 to move synchronously along the preset radial path, so that the tool 6 strictly follows the contour trajectory of the template to complete high-precision contour cutting. In the production scenario of small batches and multiple varieties of irregular flanges, the programming and debugging time is significantly shortened, and the inherent defects such as large positioning error, low efficiency and poor consistency in the manual line drawing and simple track cutting mode are effectively improved.

[0024] In this way, by adjusting the rotation of the worktable 1 in conjunction with the coordinated operation of the quick-change template 20 and the contouring component, the complex contour dimensions of the irregular wind turbine flange are transformed into proportional displacement parameters that the execution unit can recognize. This drives the three-dimensional moving frame 3 and the bottom cutter 6 to achieve high-fidelity cutting of the workpiece. This not only eliminates the random errors caused by traditional manual drawing and simple track cutting, but also improves the geometric accuracy and batch consistency of product processing. At the same time, with the fixing method of the fixture 4 and the design of the modular quick-change template 20, the device can quickly complete the changeover and debugging without cumbersome CNC programming when facing the production of small batches and multiple varieties of non-standard flanges. This shortens the production preparation cycle, reduces the technical threshold and labor costs, and solves the pain points of low efficiency, poor flexibility and high equipment occupancy in the traditional processing mode.

[0025] Furthermore, a support frame 2 is provided above the workbench 1, and a cylinder 7 is fixedly installed at the bottom of the support frame 2. A fixing rod 8 is fixedly installed at the output end of the cylinder 7. A chuck 18 is rotatably connected to the bottom of the fixing rod 8 through a fixing sleeve 21. A fixing tube 19 is slidably installed on the inner ring of the quick-change template 20.

[0026] The above implementation scheme provides a specific installation method for the quick-change template 20. See details below. Figure 7 When installing the quick-change template 20, first slide the quick-change template 20 into the fixed tube 19 along the inner ring, put the bottom end of the fixed tube 19 into the clamping cavity of the chuck 18, and tighten the chuck 18 to firmly clamp the fixed tube 19. This quickly completes the positioning and fixing of the quick-change template 20. The self-centering clamping structure of the chuck 18 ensures that the axial and radial reference heights of the quick-change template 20 coincide, thereby ensuring the geometric reference uniformity and repeatability of the contour trajectory. This allows the tool 6 to run stably along the same theoretical contour trajectory after each template change, avoiding cumulative errors caused by template installation deviations and significantly improving the consistency of multiple batches of processing. Furthermore, the cylinder 7 drives the fixed rod 8 to move the chuck 18 precisely up and down in the vertical direction, adapting to the installation requirements of quick-change templates 20 of different thicknesses.

[0027] Furthermore, the contouring component includes a rotating block 11 fixedly installed on the outer wall of a fixed sleeve 21, and sliding blocks 10 rotatably installed on both sides of the outer wall of the rotating block 11. The outer walls of the two sliding blocks 10 are provided with sliding pins. The outer wall of the fixed sleeve 21 is fitted with a sliding groove 9 that allows the sliding blocks 10 to slide within it. The outer wall of the rotating block 11 is ball-jointed with two sets of opposing sliding rods 12. The two sets of sliding rods 12 are slidably installed at both ends inside the sliding groove 9, and springs 13 are provided between the two sets of sliding rods 12 and the two ends inside the sliding groove 9.

[0028] A specific implementation of the contouring component is provided based on the above embodiments. See details below. Figure 6 Since the fixed sleeve 21 is fixedly connected to the fixed rod 8, the sliding sleeve 9 is rotatably connected to the sliding block 10, allowing the sliding sleeve 9 to rise and fall synchronously with the fixed sleeve 21 and rotate flexibly around its axis. The sliding sleeve 9 can slide relative to the sliding block 10 along the sliding pin axis, so that the sliding sleeve 9 can freely extend and retract along the axis while rotating around the axis, thereby accurately adapting to the surface curvature change of the quick-change template 20. The compression spring 13 set between the sliding rod 12 and the end of the sliding sleeve 9 provides adaptive preload when the sliding sleeve 9 is axially displaced, dynamically compensating for small deformations and installation tolerances during the processing.

[0029] Furthermore, the execution unit includes a slant bar 14 fixedly installed at the bottom of the sliding plate 9, a worm gear 22 that can be vertically slidably adjusted in the middle of the worktable 1, a keyway at the bottom of the fixed tube 19 that allows the top of the worm gear 22 to be inserted, a fixed rail 26 fixedly installed on the outer wall of the worm gear 22, a slider 27 slidably installed on the fixed rail 26, a tension spring between the slider 27 and the end of the fixed rail 26, a sliding seat 16 fixedly installed at the top of the slider 27 via a support, a roller 17 rotatably installed on the sliding seat 16 that can contact and abut against the outer wall of the quick-change template 20, and a universal rod 15 rotatably connected between the sliding seat 16 and the slant bar 14.

[0030] A specific implementation method for an execution unit is provided based on the above embodiments. See details below. Figure 7 When the external drive structure drives the quick-change template 20 to rotate, the roller 17 rolls along the outer wall of the template. The motion is decoupled and transmitted to the inclined rod 14 through the universal rod 15. The inclined rod 14 swings accordingly, causing the sliding block 9 to slide horizontally and rotate axially at the same time. This drives the sliding block 10 to move axially along the sliding pin, triggering the sliding rod 12 to compress the spring 13. The spring 13 generates a reverse elastic restoring force, which offsets the instantaneous impact caused by the sudden change in the curvature of the template in real time. In addition, the guide structure formed by the fixed rail 26 and the slider 27, together with the tension spring, ensures that the roller 17 is always in close contact with the curved surface of the template, achieving gapless following. The tension spring and the dynamic response of the spring 13 work together to maintain force control stability under both continuous curvature change and step change conditions, thereby ensuring the accuracy of the processing trajectory and the consistency of surface finish.

[0031] In this way, by tightly fitting the roller 17 against the outer wall of the quick-change template 20, and by combining the sliding of the slider 27 on the fixed rail 26 with the pre-tightening effect of the tension spring, a highly sensitive contour following feedback mechanism is constructed. When the curvature of the template contour changes abruptly, the universal rod 15 decouples and transmits the swing displacement of the inclined rod 14, driving the sliding rod 9 to generate a composite motion of horizontal sliding and axial rotation. This forces the sliding rod 12 to compress the spring 13, using elastic potential energy to buffer and absorb the impact of the motion in real time. This not only effectively eliminates the backlash and clearance in the mechanical transmission chain, ensuring a high-fidelity reproduction of the tool 6's movement trajectory to the template contour, but also achieves dynamic compensation for instantaneous overload through the reverse elastic restoring force of the spring 13. This prevents the tool 6 from jamming or the motor from overloading due to abrupt changes in the contour, significantly improving the equipment's operational stability, impact resistance, and long-term mechanical reliability when dealing with complex irregular flange processing.

[0032] Furthermore, a connecting seat 29 is fixedly installed on the outer wall of the three-dimensional moving frame 3, and a connecting rod 28 is horizontally slidably installed inside the connecting seat 29. One end of the connecting rod 28 is rotatably connected to the sliding joint 9, and the other end of the connecting rod 28 is fixedly connected to the rotating rod 5.

[0033] As can be seen from the above implementation method, when the sliding groove 9 generates a composite displacement due to the change in the curvature of the template, the connecting rod 28 will also undergo horizontal displacement and drive the rotating rod 5 to deflect synchronously. Since the connecting rod 28 is restricted by the connecting seat 29 to slide only in the horizontal direction, the axial rotation component of the sliding groove 9 is constrained to be transmitted only through horizontal sliding. The axial rotation trend of the sliding groove 9 is converted into the pure translational output of the connecting rod 28, which can amplify the small displacement generated by the roller 17 rolling along the outer wall of the quick-change template 20, significantly improve the movement range of the rotating rod 5, and thus more accurately control the radial feed and cutting angle of the tool 6.

[0034] In this way, by using the horizontal sliding constraint of the connecting seat 29 on the connecting rod 28, the originally complex composite displacement motion of the sliding rod 9 is decoupled into a single pure translational output, effectively eliminating the interference of the axial rotation component on the rotating rod 5, and ensuring the accuracy and directionality of power transmission. At the same time, by utilizing the lever principle and the linkage mechanism, this structure can proportionally amplify the minute contour changes collected by the roller 17, significantly improving the response sensitivity of the tool 6 to the subtle features of the irregular curved surface and the radial feed stroke. This not only realizes the linear transformation from contour perception to cutting execution and avoids motion interference, but also greatly enhances the adaptability of the device to large curvature abrupt changes and complex contours. While ensuring high contour accuracy, it further improves the adjustment range and stability of the cutting inclination angle, thereby ensuring that the tool 6 can obtain the best cutting posture under different cutting angles, effectively suppressing the vibration phenomenon, and improving the quality of the cut surface and processing efficiency.

[0035] Furthermore, a rotating shaft 24 is rotatably mounted on the side wall of the workbench 1. A handwheel 25 is fixedly mounted on one end of the rotating shaft 24, and a worm wheel 23 that meshes with the worm 22 is fixedly mounted on the other end of the rotating shaft 24. The outer wall of the worm 22 is connected to the workbench 1 by a thread.

[0036] As can be seen from the above implementation method, since the quick-change template 20 needs to rotate synchronously with the worktable 1, and the quick-change template 20 is clamped by the chuck 18, after the chuck 18 completes the workpiece clamping, rotating the handwheel 25 can drive the worm gear 23 to drive the worm 22 to feed axially, so that the top of the worm 22 rises and inserts into the slot at the bottom of the chuck 18. The rotation lock is achieved through the wedge-shaped fit between the chuck 18 and the worm 22, thereby ensuring that the quick-change template 20 and the worktable 1 rotate rigidly and synchronously. This achieves high-precision synchronous coupling between the quick-change template 20 and the spindle rotation without affecting the quick-change function of the quick-change template 20. When the template needs to be replaced, rotating the handwheel 25 in the opposite direction causes the worm 22 to retract and disengage from the slot, and the chuck 18 and the quick-change template 20 are then released from rigid constraint, which facilitates quick disassembly and replacement.

[0037] In this way, the rotation of the rotating shaft 24 and the worm gear 23 is driven by the handwheel 25. With the threaded transmission between the worm 22 and the worktable 1, the rotational motion is precisely converted into the axial lifting displacement of the worm 22. The wedge-shaped engagement between the top of the worm gear 22 and the bottom of the chuck 18 enables fast and reliable rigid locking and releasing. This ensures that the quick-change template 20 and the worktable 1 maintain high-precision synchronous rotational rigidity while retaining the convenience of quick template replacement. It is not only easy to operate, saving time and effort, but also avoids the cumbersome disassembly and assembly process caused by traditional flange connections or bolt tightening. Moreover, thanks to the inherent self-locking characteristics of the worm gear 23 and worm 22 transmission, the locked state is extremely stable, which can effectively resist high-frequency vibration and torque impact during the cutting process, prevent the template from loosening and deviating, and ensure the trajectory accuracy of the contour processing. It also greatly improves the production efficiency and operational safety of the equipment when switching between workpieces of different specifications, achieving a perfect unity of quick change and high-precision synchronization.

[0038] Furthermore, the diagonal bar 14 is inclinedly set at the bottom end of the sliding joint 9, and the angle between the diagonal bar 14 and the sliding joint 9 can be adjusted by the locking device, and the middle connecting rod of the universal rod 15 is connected by a flange.

[0039] As can be seen from the above implementation method, since the axial rotation component of the sliding rod 9 is constrained to be transmitted only through horizontal sliding, the tilt angle adjustment of the inclined rod 14 can dynamically match the contour trajectory requirements of workpieces with different curvatures, so that the universal rod 15 always maintains the optimal contact angle and pressure distribution during the follow-up process, thereby improving the fit and response sensitivity between the roller 17 and the workpiece surface.

[0040] Furthermore, a displacement sensor is provided at the end of the fixed rail 26, and a tension sensor is provided on the slider 27. Both the displacement sensor and the tension sensor are electrically connected to the external control unit. The external control unit is configured to calibrate the radial movement coordinates of the three-dimensional moving frame 3 in real time based on the position information of the slider 27 fed back by the displacement sensor, and dynamically adjust the downward driving force of the cylinder 7 according to the feedback value of the tension sensor to ensure that the contact pressure of the roller 17 on the quick-change template 20 is constant.

[0041] As can be seen from the above implementation method, by capturing the minute displacement of the slider 27 on the fixed rail 26 in real time by the displacement sensor, it is equivalent to digitizing the physical contour of the quick-change template 20. The external control unit performs dynamic coordinate compensation on the three-dimensional moving frame 3 accordingly, ensuring that the actual travel path of the cutter 6 is highly consistent with the theoretical design contour. At the same time, the tension sensor senses that the contact force between the roller 17 and the template deviates from the preset threshold. If the resistance changes abruptly due to unevenness of the template surface or foreign objects, the control unit immediately adjusts the output air pressure of the cylinder 7 in the opposite direction. While preventing the template from deforming due to overpressure, it avoids template jumping or misalignment due to underpressure, so that the device can maintain a constant high-precision cutting state when facing quick-change templates 20 of different materials and thicknesses.

[0042] Furthermore, the tilt angle between the diagonal bar 14 and the bottom end of the sliding joint 9 is set to between 45 degrees and 135 degrees.

[0043] As can be seen from the above implementation method, the setting of the angle range is intended to optimize the balance between force transmission efficiency and motion sensitivity, effectively avoiding the "dead point" or transmission lag that may occur in the mechanism at extreme positions such as close to 0 degrees or 180 degrees. When the tilt angle is set between 45 degrees and 135 degrees, the inclined bar 14 can efficiently decompose the horizontal radial displacement generated by the sliding flange 9 into the axial push-pull force required by the universal rod 15. This ensures that the roller 17 responds quickly to the micro-contour changes of the quick-change template 20, and can also appropriately amplify or reduce the displacement ratio through the lever principle, thereby adapting to the contouring requirements of different scaling ratios. In addition, this range allows sufficient physical clearance space between the inclined bar 14 and the sliding flange 9 to prevent mechanical interference caused by excessive workpiece size or sudden changes in template curvature, significantly improving the running stability and structural reliability of the device when processing large-thickness, large-diameter irregular flanges.

[0044] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the specification and drawings can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
