Description

Technical Field

[0001] This utility model relates to the field of structural core material processing technology, specifically to a cutting device. Background Technology

[0002] Wind turbine blades are the core components of wind turbine generators, and their performance directly affects the efficiency of converting wind energy into electrical energy. The blade core material is a critical component of the blade. By employing a sandwich structure in the leading edge, trailing edge, and web of the blade, the blade's weight can be reduced, structural stiffness increased, and local instability prevented, thereby improving the overall load-bearing capacity of the blade. This requires reducing blade weight while ensuring blade stability, and increasing the wind-catching area while meeting stiffness requirements.

[0003] Because wind turbine blades are designed according to complex aerodynamic principles and mechanical performance requirements, their contours are typically irregular, resulting in irregular shapes for the inner walls of the blade cavity. To achieve a good fit between the core material and the inner wall of the wind turbine blade, and to ensure the stability and reliability of the overall blade structure, precise cutting and chamfering of the core material are usually required. Specifically, the core material is typically cut into multiple small pieces to better fit the complex and varied contours of the inner wall; simultaneously, the core material is chamfered to create a structure with specific bevels. This irregular inner wall design of the wind turbine blade means that the slope of the beveled structure on the core material is not constant, but varies as the bevel extends.

[0004] In existing technologies, foam beveling machines are mainly used to cut the core material, enabling large-scale beveling of the core material. However, existing foam beveling machines can only process beveled structures with a fixed slope, and cannot process beveled structures with varying slopes. This makes it difficult for the core material to perfectly fit the irregular inner wall of the wind turbine blade. This not only affects the overall stability of the blade structure, but also easily leads to local stress concentration, reducing the blade's load-bearing capacity and service life. Therefore, in order to fit the inner wall as closely as possible, additional manual grinding or cutting of the core material is required, which greatly increases the labor and time costs of production and reduces production efficiency. At the same time, manual grinding or cutting heavily relies on the operator's experience and skills, which can easily lead to problems such as dimensional deviations. Manual intervention not only increases labor intensity, but more importantly, frequent manual adjustments of the cutting tools are time-consuming, seriously affecting overall production efficiency.

[0005] To address this, the inventors developed a wood cutting machine capable of batch processing inclined plane structures with varying slopes, significantly reducing human intervention. Simultaneously, the inventors designed a cutting device for this wood cutting machine to automate the processing of inclined plane structures with varying slopes. Utility Model Content

[0050] The cutting device of this utility model includes a bracket, a crossbeam, a first drive mechanism, a working arm, a second drive mechanism, and a cutting mechanism. The crossbeam is horizontally arranged, and one end is movably mounted on the bracket via a first guide structure.

The second drive mechanism is disposed between the crossbeam and the working arm and is used to receive external signals to drive the working arm to move horizontally. The cutting mechanism includes a cutting component. The cutting mechanism is rotatably mounted on the other end of the working arm via an angle adjustment structure. The angle adjustment structure is used to receive external signals to drive the cutting mechanism to swing within a preset angle range, thereby changing the angle between the cutting component and the core plate to be cut.

[0051] In use, the cutting device of this utility model receives relevant cutting parameters (cutting path, angle data, etc.) from an external control system (such as a CNC system or industrial computer) and generates control signals. These control signals are then sent to the first drive mechanism, the second drive mechanism, and the angle adjustment structure. The first drive mechanism (such as a servo motor) receives the external control signals and drives the crossbeam to move up and down, adjusting the vertical position of the cutting component. The second drive mechanism (such as a servo motor) receives the external control signals and drives the working arm to move left and right, adjusting the horizontal position of the cutting component. The angle adjustment structure (such as a servo motor) receives the external control signals and drives the cutting mechanism to swing within a preset angle range, adjusting the angle between the cutting component and the core board to be cut to adapt to the geometry of the area to be cut and the cutting requirements. The operator starts the cutting program (or the cutting program starts automatically after the cutting component is in position), and the cutting component begins to operate. The operator places the core board to be cut on the conveyor belt, ensuring accurate placement for subsequent cutting. The conveyor belt moves, causing the core board to move along the feed direction, allowing the cutting component to cut the core board. During the cutting process, the first and second drive mechanisms adjust the positions of the crossbeam and working arm in real time according to the pre-set cutting path. At the same time, the angle adjustment structure adjusts the angle of the cutting components in real time according to the requirements of the cutting path, ensuring high precision and flexibility in the cutting process.

[0052] This invention's cutting device, through the coordinated operation of a first drive mechanism, a second drive mechanism, and an angle adjustment structure, achieves high-precision motion control of the cutting mechanism in three dimensions: vertical, horizontal, and angular. It can adapt to complex, multi-dimensional cutting needs, effectively avoiding dimensional deviations and surface roughness problems caused by traditional manual cutting, and ensuring the geometric accuracy of the blade core material. The entire cutting process is driven by external signals, achieving automation from three-dimensional path tracking to cutting angle adjustment. This greatly reduces reliance on operator experience and skills, avoids extensive manual intervention, and lowers labor intensity. Attached Figure Description

[0064] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0065] This embodiment provides a cutting device, such as Figure 1-6 As shown, the device includes: a support 11, a crossbeam 12, a first drive mechanism, a working arm 13, a second drive mechanism, and a cutting mechanism 14. The crossbeam 12 is horizontally arranged, with one end mounted on the support 11 via a first guide structure, allowing it to move up and down. The first drive mechanism is located between the support 11 and the crossbeam 12, and is used to receive external signals to drive the crossbeam 12 to move up and down. One end of the working arm 13 is mounted on the crossbeam 12 via a second guide structure, allowing it to move left and right. The second drive mechanism is located between the crossbeam 12 and the working arm 13, and is used to receive external signals to drive the working arm 13 to move horizontally. The cutting mechanism 14 includes a cutting component. The cutting mechanism is rotatably mounted on the other end of the working arm 13 via an angle adjustment structure. The angle adjustment structure is used to receive external signals to drive the cutting mechanism to swing within a preset angle range, thereby changing the angle between the cutting component and the core plate to be cut.

[0066] In this embodiment, the core board to be cut is generally placed on a conveying device (such as a conveyor belt) and moves along the feed direction under the drive of the conveyor belt. Alternatively, the core board to be cut can be manually moved by the operator to move it along the feed direction. The first and second drive mechanisms can be servo motors, hydraulic cylinders, or servo slides, etc. The first and second drive mechanisms can receive external control signals and perform corresponding actions according to the received control signals. The external control signals are generated by an external control device, which can be a PLC, motion controller, industrial computer, or CNC system, etc. The first and second drive mechanisms are connected to it via wired or wireless means to receive the control signals.

[0067] In this embodiment, the cutting device is used such that, when in use, the external control system (e.g., a CNC system or an industrial computer) receives relevant cutting parameters (cutting path, angle data, etc.) and generates control signals, which are then sent to the first drive mechanism, the second drive mechanism, and the angle adjustment structure. The first drive mechanism (e.g., a servo motor) receives the external control signals and drives the crossbeam 12 to move up and down, adjusting the vertical position of the cutting component. The second drive mechanism (e.g., a servo motor) receives the external control signals and drives the working arm 13 to move left and right, adjusting the horizontal position of the cutting component. The angle adjustment structure (e.g., a servo motor) receives the external control signals and drives the cutting mechanism 14 to swing within a preset angle range, adjusting the angle between the cutting component and the core board to be cut to adapt to the geometry of the area to be cut and the cutting requirements. The operator starts the cutting program (or the cutting program starts automatically after the cutting component is in place), and the cutting component begins to operate. The operator places the core board to be cut on the conveyor belt, ensuring that the core board is placed accurately for subsequent cutting. The conveyor belt moves, causing the core board to move along the feed direction, so that the cutting component cuts the core board. During the cutting process, the first drive mechanism and the second drive mechanism adjust the position of the crossbeam 12 and the working arm 13 in real time according to the preset cutting path. At the same time, the angle adjustment structure adjusts the angle of the cutting components in real time according to the requirements of the cutting path to ensure high precision and flexibility in the cutting process.

[0068] The cutting device in this embodiment achieves high-precision motion control of the cutting mechanism in three dimensions—vertical, horizontal, and angular—through the coordinated operation of the first drive mechanism, the second drive mechanism, and the angle adjustment structure. This enables it to adapt to complex, multi-dimensional cutting requirements, effectively avoiding dimensional deviations and surface roughness issues caused by traditional manual cutting, and ensuring the geometric accuracy of the blade core material. The entire cutting process is driven by external signals, automating everything from three-dimensional path tracking to cutting angle adjustment. This significantly reduces reliance on operator experience and skills, avoids extensive manual intervention, and lowers labor intensity.

[0069] The cutting device in this embodiment, further, is as follows: Figure 1-3 As shown, the first guide structure includes a first guide rail 111 and a first slider 121; the first guide rail 111 is vertically arranged on the bracket 11; the first slider 121 is arranged at one end of the crossbeam 12 and can be slidably connected with the first guide rail 111.

[0070] In this embodiment, the first guide rail 111 and the first slider 121 cooperate to provide stable guidance, ensuring that the crossbeam 12 will not deflect or wobble during its up-and-down movement. This improves the positioning accuracy of the cutting device and ensures the reliability of the cutting process.

[0071] The cutting device in this embodiment, further, is as follows: Figure 1-3 As shown, the first driving mechanism includes a first ball screw 151, a first ball nut 152, and a first motor 153; the first ball screw 151 is rotatably mounted on the bracket 11 via a first rotating connection structure; the first ball nut 152 is fixedly mounted on one end of the crossbeam 12 and can be screwed into the first ball screw 151; the first motor 153 is fixedly mounted on the bracket 11, and its output end is connected to the first ball screw 151 to drive the first ball screw 151 to rotate in both directions.

[0072] In this embodiment, the first motor 153 can be a servo motor with a braking function. The first ball screw 151, the first ball nut 152, and the first motor 153 provide high-precision transmission control to ensure the vertical movement accuracy of the crossbeam 12. The ball screw drive has the characteristics of high precision and high transmission efficiency, which can realize the precise vertical movement and positioning of the crossbeam 12. The ball screw drive can withstand a large axial load, ensuring the stable operation of the crossbeam. The output end of the first motor 153 and the first ball screw 151 can be connected by a coupling 102.

[0073] The cutting device in this embodiment, further, is as follows: Figure 4 , Figure 5As shown, the first rotating connection structure includes a first mounting shaft 154, a first bearing housing 161, a first bearing 162, a first bushing 163, a second bushing 164, a first end cap 165, and a first set screw locking nut 166. The first mounting shaft 154 is formed at both ends of the first ball screw 151, and the outer diameter of the first mounting shaft 154 is smaller than the outer diameter of the first ball screw 151 to form a first stepped surface 1541. The free end of the first mounting shaft 154 is formed with an external thread. There are two first bearing housings 161, which are respectively sleeved on the two first mounting shafts. The first bearing seat 161 has a first stepped hole 1611 inside, and a second stepped surface 1612 is formed between the large diameter portion and the small diameter portion of the first stepped hole 1611; there are two sets of first bearings 162, which are respectively installed in the large diameter portions of the two first stepped holes 1611 and sleeved on the first mounting shaft 154, and the outer ring end face of one side of the first bearing 162 abuts against the second stepped surface 1612; there are two first bushings 163, which are respectively installed in the two first stepped holes 1611. The first bushing 163 is installed within the smaller diameter portion of the first stepped hole 1611 and fitted onto the first mounting shaft 154. One end face of the first bushing 163 abuts against the inner ring end face of one side of the first bearing 162, and the other end face abuts against the first stepped surface 1541. Two second bushings 164 are installed within the larger diameter portions of the two first stepped holes 1611 and fitted onto the first mounting shaft 154. One end face of the second bushing 164 abuts against the inner ring end face of the other side of the first bearing 162. Two first end caps 165 are respectively installed over the first stepped holes 1611. The first end cap 165 is fixedly connected to the first bearing seat 161 at the opening of the large diameter portion and is sleeved on the first mounting shaft 154. One end of the first end cap 165 extends into the first stepped hole 1611 and abuts against the outer ring end face on the other side of the first bearing 162. The first set screw locking nut 166 can be screwed into the first mounting shaft 154 and locked to the first mounting shaft 154 by the first set screw 1661. The inner end face of the first set screw locking nut 166 abuts against the other end face of the second bushing 164.

[0074] In this embodiment, by installing the first bearing 162 on the large-diameter portion of the stepped hole and fixing it with the first end cap 165, the axial and radial displacement of the first bearing 162 can be effectively limited, ensuring that it maintains a precise position along the axial direction during operation, which helps to improve the stability and repeatability of the transmission. The structural design of the first end cap 165 and the first set screw locking nut 166 makes the installation, removal, and adjustment of the bearing more convenient, facilitating daily maintenance and precision calibration. The first bushing 163 and the second bushing 164 cooperate with the first set screw locking nut 166 for tightening, effectively limiting the axial movement of the first ball screw 151, thereby ensuring the continuity and precision of the transmission.

[0075] Furthermore, each set of first bearings 162 includes two angular contact bearings arranged side by side. Angular contact bearings can simultaneously withstand radial and axial loads, possessing high load-bearing capacity and rigidity, making them suitable for use under high-load and high-precision conditions. The side-by-side arrangement of the two angular contact bearings can distribute the load, reducing the stress on individual bearings and improving the overall load-bearing capacity. The two side-by-side angular contact bearings can further enhance the rigidity of the device, reduce shaft deflection, and improve positioning accuracy.

[0076] The cutting device in this embodiment, further, is as follows: Figure 1-3 As shown, the second guide structure includes a second guide rail 123 and a second slider 131; the second guide rail 123 is horizontally arranged on the crossbeam 12; the second slider 131 is arranged at one end of the working arm 13 and can be slidably connected with the second guide rail 123.

[0077] In this embodiment, the second guide rail 123 and the second slider 131 ensure the stability of the working arm 13 during horizontal movement, reducing offset and vibration during the movement. This improves the positioning accuracy of the cutting device and ensures the reliability of the cutting process.

[0078] The cutting device in this embodiment, further, is as follows: Figure 1-3 As shown, the second drive mechanism includes a second ball screw 171, a second ball nut 172, and a second motor 173. The second ball screw 171 is rotatably mounted on the crossbeam 12 via a second rotating connection structure. The second ball nut 172 is fixedly mounted on one end of the working arm 13 and can be screwed into the second ball screw 171. The second motor 173 is fixedly mounted on the crossbeam 12, and its output end is connected to the second ball screw 171 to drive the second ball screw 171 to rotate in both directions.

[0079] In this embodiment, the second motor 173 can be a servo motor with a braking function. The second ball screw 171, the second ball nut 172, and the second motor 173 provide high-precision transmission control, ensuring the horizontal movement accuracy of the working arm 13. The ball screw drive has the characteristics of high efficiency and low friction, reducing energy loss and improving the operating efficiency of the cutting device. The output end of the second motor 173 and the second ball screw 171 can be connected via a coupling 102.

The stepped hole 1811 has an opening in its large diameter portion and is fitted onto the second mounting shaft 174. The second end cap 185 is fixedly connected to the second bearing seat 181. One end of the second end cap 185 extends into the interior of the second stepped hole 1811 and abuts against the outer ring end face on the other side of the second bearing 182. The second set screw locking nut 186 can be screwed into the second mounting shaft 174 and locked to the second mounting shaft 174 by the second set screw 1861. The inner end face of the second set screw locking nut 186 abuts against the other end face of the fourth bushing 184.

[0081] In this embodiment, by installing the second bearing 182 on the large-diameter portion of the stepped bore and fixing it with the second end cap 185, the axial and radial displacement of the second bearing 182 can be effectively limited, ensuring that it maintains a precise position along the axial direction during operation, which helps to improve the stability and repeatability of the transmission. The structural design of the second end cap 185 and the second set screw locking nut 186 makes the installation, removal, and adjustment of the bearing more convenient, facilitating daily maintenance and precision calibration. The third bushing 183 and the fourth bushing 184 cooperate with the second set screw locking nut 186 for tightening, effectively limiting the axial movement of the second ball screw 171, thereby ensuring the continuity and precision of the transmission.

[0082] Furthermore, each set of second bearings 182 includes two angular contact bearings arranged side by side. Angular contact bearings can simultaneously withstand radial and axial loads, possessing high load-bearing capacity and rigidity, making them suitable for use under high-load and high-precision conditions. The side-by-side arrangement of two angular contact bearings can distribute the load, reducing the stress on individual bearings and improving the overall load-bearing capacity. The two side-by-side angular contact bearings can further enhance the rigidity of the device, reduce shaft deflection, and improve positioning accuracy.

[0083] The cutting device in this embodiment, further, is as follows: Figure 6 As shown, the cutting component is a circular saw 141, and the cutting mechanism includes a saw blade motor 142 and the circular saw 141 installed at the output end of the saw blade motor 142.

[0084] In this embodiment, the cutting device further includes an angle adjustment mechanism comprising a reducer 133 and a third motor 134. The reducer 133 is fixedly installed at the other end of the working arm 13, and the housing of the saw blade motor 142 is fixedly connected to the output end of the reducer 133. The third motor 134 is fixedly installed on the reducer 133, and the output end of the third motor 134 is drively connected to the input end of the reducer 133, for driving the reducer 133 to drive the saw blade motor 142 to swing within a preset angle range.

[0085] In this embodiment, the third motor 134 can be a servo motor with a braking function. The reducer 133 can be a planetary gear reducer, harmonic reducer, RV reducer, etc. The reducer 133 and the third motor 134 work together to enable the cutting mechanism 14 to swing flexibly within a preset angle range, adapting to the cutting needs of complex geometries. This improves the flexibility and adaptability of the cutting device and meets the requirements of different cutting angles.

[0086] In this embodiment of the cutting device, the reducer 133 is an RV reducer.

[0087] Furthermore, the first guide rail 111 and the second guide rail 123 are respectively provided with bellows covers 101, which can prevent the dust generated during the cutting of the core board from falling onto the first guide rail 111 and the second guide rail 123 and affecting the transmission accuracy.

[0088] The first ball screw 151, the first rotary connection structure, and the first ball nut 152 can have the same structure as the second ball screw 171, the second rotary connection structure, and the second ball nut 172.

[0089] The outer rings of the first bushing 163, the second bushing 164, the third bushing 183, and the fourth bushing 184 are also provided with oil seals 103.

[0090] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
