Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically a clamping fixture for processing wind turbine blades. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source that has been utilized by people for a long time, mainly through windmills for pumping water and grinding grain. People are interested in how to use wind to generate electricity.

[0003] During the production of wind turbines, blades need to be cut. Existing cutting devices for wind turbine blades have poor fixation and require manual support during cutting, which is inconvenient for workers.

[0004] To address the aforementioned issues, Chinese Patent CN220362032U discloses a cutting device for processing wind turbine blades. Its key technical features are: an operating table is fixedly mounted on a base; a first mounting plate is fixedly mounted on the base; a first servo motor is fixedly mounted on the first mounting plate; the output end of the first servo motor is connected to a first thread via a coupling; a threaded sleeve is threadedly connected to the first threaded rod; a second mounting plate is slidably connected to the threaded sleeve via a first sliding mechanism; a second servo motor is fixedly mounted on the second mounting plate; a rotating shaft is provided at the output end of the second servo motor via a coupling; a cutting blade is keyed onto the rotating shaft; and a fixed plate is slidably connected to the operating table via a second sliding mechanism. This cutting device for processing wind turbine blades offers excellent fixation and eliminates the need for manual support during cutting, making it convenient for operators.

[0005] However, the existing technology only fixes the wind turbine blades by cooperating with the second threaded rod and the clamping block. Since the clamping block has a limited fixing area, it will form a point-to-surface fixation. This will cause the wind turbine blades to shift laterally during the cutting process, which is not conducive to the stability of the clamping and will affect the subsequent processing effect. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a clamping fixture for processing wind turbine blades. The enclosing structure formed by the limiting and sealing cover and the operating table achieves large-area wrapping and clamping of the blade. Combined with the increased surface friction of the rubber layer, the displacement of the blade in three-dimensional space is effectively restricted. The elastic properties of the rubber layer can further absorb vibration energy, reduce processing errors, and improve the processing quality of the blade.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for processing wind turbine blades, including an operating table; A limiting cover is rotatably connected to the upper surface of the operating table. An elastic pressure component is provided on the top of the limiting cover. The elastic pressure component includes a slide rod. A pressure plate is fixedly connected to the bottom end of the slide rod. A pressure spring is movably sleeved on the outer wall of the slide rod. A blade limiting groove is provided on the upper surface of the operating table; A rubber layer fixedly connected to the inner wall of the limiting and sealing cover; A magnetic locking assembly is installed on the upper surface of the operating table. The magnetic locking assembly is used to magnetically lock the limiting enclosure.

[0008] In a preferred embodiment of this invention, the magnetic locking assembly includes an electromagnetic coil, which is fixedly connected to the upper surface of the operating table near the front. A metal armature is fixedly connected to the bottom surface of the limiting enclosure, and the metal armature is magnetically attracted to the electromagnetic coil.

[0009] As a preferred embodiment of this invention, the front side of the operating table is provided with a control button for adjusting the magnetic locking component.

[0010] In a preferred embodiment of this invention, the top end of the slide rod extends movably through to the top of the limiting enclosure, and a positioning ring is fixedly sleeved on the outer wall of the slide rod near the top end. The bottom surface of the positioning ring is fixedly connected to the top end of the compression spring.

[0011] In a preferred embodiment of this invention, the bottom end of the pressure spring is fixedly connected to the upper surface of the limiting enclosure, a clamping plate is fixedly connected to the top of the inner wall of the limiting enclosure, a rubber layer is fixedly connected to the bottom surface of the clamping plate, and the pressure plate is movably connected to the side of the clamping plate.

[0012] As a preferred embodiment of this utility model, the upper surface of the operating table near the rear side is provided with an installation groove, and the limiting and sealing cover is rotatably connected to the inner wall of the installation groove through a rotating rod.

[0013] As a preferred embodiment of this utility model, a handle is fixedly connected to the front side of the limiting enclosure, and a cutting groove is provided on the upper surface of the operating table near one end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The magnetic locking assembly of this utility model achieves locking through the magnetic attraction between the electromagnetic coil and the metal armature. Combined with the one-button control of the control button, it significantly shortens the time for blade assembly and disassembly compared to traditional mechanical locks, and improves processing efficiency. Moreover, the magnetic attraction locking method distributes force evenly, avoiding the clamping failure problem caused by loose fasteners in mechanical locking, and significantly enhancing the stability of the processing.

[0015] 2. This utility model can automatically adjust the pressure of the pressure plate according to the blade thickness by using the elastic restoring force of the pressure spring in the elastic pressure assembly. This can ensure stable clamping of blades of different thicknesses, avoid damage to the blade surface and internal structure caused by rigid clamping, and effectively buffer the vibration generated during processing, thereby further improving the positioning accuracy.

[0016] 3. This utility model achieves large-area wrapping and clamping of the blade through the enclosed structure formed by the limiting and sealing cover and the operating table. Combined with the increased surface friction of the rubber layer, it effectively restricts the displacement of the blade in three-dimensional space. The elastic properties of the rubber layer can further absorb vibration energy, reduce processing errors, and improve the processing quality of the blade.

[0017] 4. This utility model achieves synergy between the pre-positioning function of the blade limiting groove and the avoidance function of the cutting groove. The blade limiting groove ensures the accuracy of the initial position of the blade, while the cutting groove provides a safe working space for the tool and avoids interference between the tool and the operating table. This not only protects the tooling and the tool, but also provides a guarantee for high-precision cutting. Attached Figure Description

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention, which provides a clamping fixture for processing wind turbine blades, including an operating table 1; A limiting cover 2 is rotatably connected to the upper surface of the operating table 1. An elastic pressure component is provided on the top of the limiting cover 2. The elastic pressure component includes a slide rod 14. A pressure plate 13 is fixedly connected to the bottom end of the slide rod 14. A pressure spring 15 is movably sleeved on the outer wall of the slide rod 14. A blade limiting groove 6 is provided on the upper surface of the control panel 1; A rubber layer 9 is fixedly connected to the inner wall of the limiting and sealing cover 2; The magnetic locking assembly is installed on the upper surface of the control panel 1. The magnetic locking assembly is used to magnetically lock the limiting enclosure 2.

[0025] The magnetic locking assembly includes an electromagnetic coil 7, which is fixedly connected to the upper surface of the operating table 1 near the front. A metal armature 8 is fixedly connected to the bottom surface of the limiting enclosure 2, and the metal armature 8 is magnetically attracted to the electromagnetic coil 7. A control button 5 for adjusting the magnetic locking assembly is provided on the front side of the operating table 1.

[0026] Specifically, the elastic restoring force of the pressure spring 15 in the elastic pressure assembly can automatically adjust the pressure of the pressure plate 13 according to the blade thickness. This ensures stable clamping of blades of different thicknesses, avoids damage to the blade surface and internal structure caused by rigid clamping, and effectively buffers the vibration generated during processing, further improving positioning accuracy.

[0027] Example 2 The second embodiment of this utility model provides a technical solution: the top end of the slide rod 14 extends movably through to the top of the limiting enclosure 2, and a positioning ring is fixedly sleeved on the outer wall of the slide rod 14 near the top end, and the bottom surface of the positioning ring is fixedly connected to the top end of the pressure spring 15.

[0028] The bottom end of the pressure spring 15 is fixedly connected to the upper surface of the limiting cover 2. The top of the inner wall of the limiting cover 2 is fixedly connected to the clamping plate 12. The bottom surface of the clamping plate 12 is fixedly connected to the rubber layer 9. The pressure plate 13 is movably connected to the side of the clamping plate 12.

[0029] The upper surface of the control panel 1 near the rear is provided with a mounting groove 11, and the limiting and sealing cover 2 is rotatably connected to the inner wall of the mounting groove 11 through the rotating rod 10.

[0030] A handle 3 is fixedly connected to the front side of the limiting and sealing cover 2, and a cutting groove 4 is opened on the upper surface of the operating table 1 near one end.

[0031] Specifically, the enclosing structure formed by the limiting enclosure 2 and the operating table 1 achieves large-area wrapping and clamping of the blade. Combined with the increased surface friction of the rubber layer 9, it effectively restricts the displacement of the blade in three-dimensional space. The elastic properties of the rubber layer 9 can further absorb vibration energy, reduce processing errors, and improve the processing quality of the blade.

[0032] Example 3 The third embodiment of this utility model provides a technical solution: a linear bearing is fixedly embedded at the top of the limiting and sealing cover 2 corresponding to the through-hole of the slide rod 14. The inner ring of the linear bearing is clearance-fitted with the outer wall of the slide rod 14 to achieve smooth sliding of the slide rod 14 and avoid radial shaking.

[0033] The electromagnetic coil 7 is connected to the operating table 1 via a fixed base. The fixed base is connected to the upper surface of the operating table 1 by welding or bolt fastening. The electromagnetic coil 7 is embedded inside the fixed base, and the top of the fixed base is higher than the top of the electromagnetic coil 7 to prevent the enclosure from squeezing the coil.

[0034] Control button 5 is connected to relay via wire. Relay, electromagnetic coil 7 and external power supply are connected in series to form control circuit. Control button 5 has two positions: 'power on lock' and 'power off unlock', to achieve precise control of magnetic locking. The operating table 1 has a wire groove inside to hide the connecting wires and prevent them from being damaged during processing.

[0035] Working principle: Before cutting the blade, the operator places the blade to be processed in the blade limiting groove 6 opened on the upper surface of the operating table 1. The blade limiting groove 6 achieves preliminary positioning through a structure that matches the bottom contour of the blade, thus preventing the blade from shifting laterally.

[0036] The operator holds the handle 3 fixedly connected to the front of the limiting cover 2 and rotates the limit cover 2 towards the operating table 1 with the rotating rod 10 in the mounting groove 11 near the rear upper surface of the operating table 1 as the axis of rotation until the limit cover 2 is aligned with the upper surface of the operating table 1. At this time, the blade is surrounded and wrapped by the limit cover 2 and the operating table 1, achieving large-area initial clamping.

[0037] When the limiting cover 2 is flipped to the docking position with the operating table 1, the magnetic locking component is adjusted by the control button 5 on the front side of the operating table 1. The electromagnetic coil 7, which is fixedly connected to the upper front surface of the operating table 1, is energized and generates magnetism. It magnetically attracts the metal armature 8, which is fixedly connected to the bottom surface of the limiting cover 2, thereby stably locking the limiting cover 2 to the operating table 1 and preventing the cover from loosening during the processing.

[0038] As the limiting and sealing cover 2 completes its closing action, the bottom surface of the pressure plate 13, which is fixedly connected to the bottom end of the slide rod 14, comes into close contact with the upper surface of the blade. As the closing action continues, the blade generates an upward reaction force on the pressure plate 13, pushing the slide rod 14 upward along the through hole at the top of the limiting and sealing cover 2. Simultaneously, the positioning ring near the top outer wall of the slide rod 14 moves upward, stretching the pressure spring 15 (whose bottom end is fixedly connected to the upper surface of the limiting and sealing cover 2) that is movably sleeved on the outer wall of the slide rod 14. Utilizing the elastic restoring force of the pressure spring 15, the pressure plate 13 applies continuous and gentle downward pressure to the blade, further enhancing clamping stability. Furthermore, the bottom surface of the clamping plate 12, which is fixedly connected to the top of the inner wall of the limiting and sealing cover 2, is provided with a rubber layer 9. During clamping, this increases the friction with the blade surface while preventing damage to the blade from rigid contact.

[0039] During processing, the cutting tool can operate along the cutting groove 4 opened on the upper surface of the operating table 1 near one end. The cutting groove 4 provides clearance for the cutting action, preventing the tool from colliding with the operating table 1 and ensuring the safety and accuracy of the processing.

[0040] In summary: the enclosed structure formed by the limiting cover 2 and the operating table 1 achieves large-area wrapping and clamping of the blade, and the increased surface friction of the rubber layer 9 effectively restricts the displacement of the blade in three-dimensional space; the elastic properties of the rubber layer 9 can further absorb vibration energy, reduce processing errors, and improve the processing quality of the blade.
