Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a laser cutting device for processing wave shields. Background Technology

[0002] Baffles are critical safety devices inside the tanks of chemical transport tank trucks. Installed inside the tank, their main function is to suppress and reduce severe sloshing of the liquid inside the tank during operation (i.e., "liquid sloshing"), ensuring the vehicle's stability.

[0003] In the prior art, the national authorized patent announcement number CN222078307U discloses a cutting device for sheet metal processing. The usage process of this device is as follows: first, connect the power supply and press the main switch to control the power supply of the main body of the cutting device; then, turn on the laser cutting module through the operation panel to allow the laser cutting module to complete the preheating operation before cutting. The laser cutting module is the core cutting component of the device, integrating a laser generator, cutting head, focusing lens, and other structures, and can cut sheet metal parts through a high-power laser beam. During the preheating process of the laser cutting module, the operator places the sheet metal part to be processed on the lower clamping plate. The lower clamping plate is located at the connection point on the left and right sides of the top of the main body of the cutting device, and can cooperate with the upper clamping plate to position and clamp the sheet metal part. Then, the operator turns the adjusting screw, and the adjusting screw applies pressure to the upper clamping plate to fix the sheet metal part. A rubber plate is also installed between the lower clamping plate and the upper clamping plate, which can play a role in buffering, anti-wear, and preventing cutting damage.

[0004] However, when this sheet metal cutting device is applied to the cutting of wave deflectors, numerous compatibility defects emerge. The device uses a clamping method with upper and lower flat plates, both of which are planar structures. This prevents the device from conforming to the undulating corrugated contours of the wave deflector. When clamping the wave deflector, it only contacts the crests of the corrugations, resulting in point-contact clamping. This not only fails to achieve stable positioning of the wave deflector but also easily leads to uneven force distribution, causing displacement and loosening. Furthermore, significant clamping gaps form at the troughs of the corrugations, and vibrations generated during cutting severely affect the cutting accuracy. Additionally, the device requires manual adjustment of the adjusting screws. The device suffers from low efficiency in adjusting clamping pressure and cannot adjust the clamping position by retracting or expanding the clamping mechanism. This makes it difficult to adapt to baffles of different widths and corrugation spacings, resulting in poor versatility. Furthermore, the device lacks a dedicated slag collection structure, causing a large amount of slag generated during baffle cutting to accumulate on the surface of the clamping plate, the cutting table, and around the laser cutting module. This not only wears down the rubber buffer layer, affecting clamping stability, but also contaminates the laser focusing lens, thereby reducing cutting performance and shortening the equipment's lifespan. Summary of the Invention

[0005] The purpose of this invention is to provide a laser cutting device for processing wave shields, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A laser cutting device for processing wave deflectors includes: a U-shaped frame, with transmission grooves at both ends of the inner side of the U-shaped frame; multiple sets of U-shaped toothed plates are fixedly installed at equal intervals between the lower surfaces of the two sets of transmission grooves; clamping mechanisms are driven and installed in both sets of transmission grooves; a contraction and expansion mechanism is threaded between the lower surfaces of the two sets of clamping mechanisms; the contraction and expansion mechanism is fixedly installed inside the U-shaped frame; the contraction and expansion mechanism can synchronously drive the two sets of clamping mechanisms, causing the two sets of clamping mechanisms to contract or expand towards the center within the distance between adjacent sets of U-shaped toothed plates; a three-axis slide is fixedly installed between the upper surfaces of the U-shaped frame, and a laser cutting execution module is fixedly installed at one end of the three-axis slide.

[0007] The aforementioned laser cutting device for processing wave deflectors includes: multiple sets of funnel-shaped slag discharge ports are equidistantly arranged inside the U-shaped frame; the lower ends of the multiple sets of slag discharge ports are correspondingly connected to insertion ports; the multiple sets of insertion ports are equidistantly arranged on the lower surface of the U-shaped frame; and a receiving plate trolley is slidably inserted into the insertion ports.

[0008] In the aforementioned laser cutting device for processing wave deflectors, an L-shaped limiting block is fixedly installed at one end of the insertion port. When the receiving plate trolley is slidably inserted into the insertion port and touches one end of the L-shaped limiting block, the receiving chamber of the receiving plate trolley and the slag discharge port are arranged perpendicularly to each other.

[0009] The aforementioned laser cutting device for processing wave deflectors includes: the expansion and contraction mechanism comprising two sets of first motors, which are respectively fixedly installed at both ends within the U-shaped frame; one end of the output shaft of each of the two sets of first motors is fixedly connected to a bidirectional forward and reverse threaded screw; the outer surfaces of the forward and reverse threaded screw sections of the two sets of bidirectional forward and reverse threaded screws are threaded with traction blocks; the two sets of traction blocks on the outer surface of each set of bidirectional forward and reverse threaded screws are rotatably connected to the lower surfaces of two sets of clamping mechanisms installed in the transmission groove via elongated openings; the elongated openings are located at both ends of the upper surface within the U-shaped frame.

[0010] In the aforementioned laser cutting device for processing wave deflectors, a guide rail block is fixedly installed on the upper surface of the traction block, and the guide rail block is embedded and slidably installed in the guide rail groove opened on the lower surface of the elongated opening.

[0011] The aforementioned laser cutting device for processing wave deflectors includes: a clamping mechanism comprising two sets of transmission columns, which are rotatably disposed at both ends within a transmission groove. Each set of transmission columns is rotatably mounted within a traction block after passing through a long slot via a shaft fixedly mounted on its lower surface; a transmission belt is fitted between the outer surfaces of the two sets of transmission columns; multiple guide openings are equidistantly provided on both sides of the transmission belt; a set of T-shaped plates is slidably installed within each of the multiple guide openings on both sides of the transmission belt; and multiple sets of first and second clamps are equidistantly fixedly installed at one outer end of each of the two sets of T-shaped plates.

[0012] In the aforementioned laser cutting device for processing wave deflectors, the initial position of the first top clamp is that the T-shaped plate slides at the top of the guide opening, and the initial position of the second top clamp is that the T-shaped plate slides at the bottom of the guide opening, so that the first top clamp and the second top clamp are respectively located at the upper end and the lower end of the U-shaped toothed plate.

[0013] The aforementioned laser cutting device for processing wave deflectors comprises: each set of first and second clamps arranged in an alternating pattern and placed within the spacing between two adjacent sets of U-shaped toothed plates; the first and second clamps are respectively adapted to the corrugated grooves on the upper and lower surfaces of the wave deflector and correspondingly press against the corrugated grooves on the upper and lower surfaces of the wave deflector; when the transmission belt is driven, it can respectively drive the first and second clamps to move back and forth in opposite directions, and the distance of the displacement does not exceed the spacing length between two adjacent sets of U-shaped toothed plates; the pressing heads of the first and second clamps are both integrally molded from polyurethane elastic material.

[0014] The aforementioned laser cutting device for processing wave deflectors comprises: a first support plate and a second support plate rotatably mounted between the upper and lower surfaces of the two sets of transmission columns; a second motor fixedly mounted on the lower inner surface of the first support plate; a third motor fixedly mounted on the upper outer surface of the second support plate; threaded rods fixedly mounted on the output shafts of both the second and third motors; push-pull blocks threadedly mounted on the outer surfaces of the threaded rods; and two sets of push-pull blocks slidably mounted in sliding grooves opened inside the first and second clamps, respectively. The second and third motors can drive the threaded rods to rotate, thereby driving the push-pull blocks to push the first clamp downward and pull the second clamp upward, causing them to move perpendicularly in opposite directions.

[0015] The aforementioned laser cutting device for processing wave deflectors includes a fourth motor fixedly mounted on one end of the upper surface of the first support plate, wherein the output shaft of the fourth motor is fixedly connected to one of the sets of transmission columns.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Improved clamping adaptability and versatility: The retraction and expansion mechanism, driven by the first motor, drives the bidirectional forward and reverse threaded rods to synchronously retract or expand the clamping mechanism, achieving automated adjustment of the clamping width and adapting to baffles of different widths. The clamping mechanism, through the coordinated control of the fourth, second, and third motors, achieves bidirectional displacement adjustment of the first and second top clamps in both forward and vertical directions, adapting to baffles with different corrugation spacing and depths. This eliminates the need to replace clamping components, significantly improving the device's adaptability and versatility to baffles of different specifications and solving the problem of poor versatility in traditional devices.

[0017] 2. Achieving precise and stable clamping of the baffle plate: The U-shaped toothed plate provides initial support and center positioning for the baffle plate. The first and second top clamps of the clamping mechanism are staggered and can accurately fit and press against the corrugated grooves on the upper and lower surfaces of the baffle plate, achieving surface contact clamping, which replaces the traditional point contact clamping method. This avoids the baffle plate from shifting or loosening due to uneven force, and the vibration during the cutting process will not affect the positioning accuracy, ensuring the stability and precision of the baffle plate clamping.

[0018] 3. Improve the automation and efficiency of cutting operations: This device achieves fully automated operation of clamping width adjustment, precise corrugated groove pressing, and cutting head displacement adjustment through the linkage control of various motors. It eliminates the need for manual adjustment of the components for clamping and positioning, greatly reducing manual operation steps and the workload of operators. At the same time, it improves the overall efficiency of baffle clamping and cutting, and solves the problem of low adjustment efficiency of traditional devices.

[0019] 4. Ensure the surface quality of the baffle plate: The top pressure heads of the first and second top clamps are made of polyurethane elastic material in one piece. The elastic material allows the top clamps to fit more tightly with the corrugated grooves of the baffle plate, while buffering the force during clamping and avoiding scratches or pressure damage to the corrugated surface of the baffle plate caused by the hard top clamps, thus ensuring the surface processing quality of the baffle plate after cutting.

[0020] 5. Achieve centralized slag collection, protecting equipment and reducing maintenance costs: The spacing design of the U-shaped toothed plates, combined with the funnel-shaped slag discharge port, guides the cutting slag to fall quickly and smoothly, preventing slag accumulation on the cutting table and baffle plate surface; the L-shaped limiting block ensures precise alignment between the receiving trolley and the slag discharge port, achieving accurate slag collection and preventing slag leakage to other parts of the equipment. This prevents slag from wearing down the clamping components of the equipment and contaminating the laser cutting execution module, ensuring the stable cutting effect of the laser cutting execution module. At the same time, it reduces the probability of equipment failure, extends the service life of various components, and lowers equipment maintenance costs.

[0021] 6. Improved cutting accuracy and processing quality: The three-axis slide table drives the laser cutting execution module to achieve flexible multi-directional displacement, which can accurately match the corrugated contour and irregular structure of the wave deflector to complete the cutting operation. Combined with the stable clamping effect of the wave deflector, it avoids the problem of wave deflector displacement during the cutting process, greatly improves the cutting accuracy of the wave deflector, ensures the overall processing quality of the wave deflector, and meets the processing requirements of the shipbuilding, marine engineering and other industries for wave deflectors.

[0022] 7. Ensure the stability and smoothness of equipment operation: The embedded sliding fit between the guide block and the guide groove provides guidance and limit for the sliding of the traction block, avoiding sliding deviation or jamming; the guide port limits the sliding of the T-shaped plate, and the sliding groove guides the sliding of the push-pull block. The limit and guide design of each component makes the transmission process of the device smoother, reduces friction and wear between components, reduces noise during equipment operation, and ensures the overall stability and smoothness of equipment operation.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-6 This embodiment provides a laser cutting device for processing wave deflectors, including: a U-shaped frame 1, with transmission grooves 101 at both ends of the inner side of the U-shaped frame 1, and multiple sets of U-shaped toothed plates 104 fixedly installed at equal intervals between the lower surfaces of the two sets of transmission grooves 101, with clamping mechanisms 2 installed in both sets of transmission grooves 101, and a contraction and expansion mechanism 3 threaded between the lower surfaces of the two sets of clamping mechanisms 2, which is fixedly installed in the U-shaped frame 1. The contraction and expansion mechanism 3 can synchronously drive the two sets of clamping mechanisms 2, so that the two sets of clamping mechanisms 2 move closer to the center or expand outward within the distance between the two sets of adjacent U-shaped toothed plates 104; a three-axis slide 102 is fixedly installed between the upper surfaces of the U-shaped frame 1, and a laser cutting execution module 103 is fixedly installed at one end of the three-axis slide 102.

[0027] In this design, the U-shaped frame 1 serves as the basic support component of the device, providing a stable carrier for the installation of the transmission groove 101, U-shaped toothed plate 104, clamping mechanism 2, expansion mechanism 3, three-axis slide table 102, and laser cutting execution module 103, ensuring the structural stability of each component after installation. The transmission groove 101 provides suitable space for the installation and displacement of the clamping mechanism 2, while also providing initial guidance for the displacement direction of the clamping mechanism 2, preventing significant swaying during displacement. The U-shaped toothed plates 104 are evenly distributed, providing initial support and positioning for the wave-damping plates placed on them, preventing positional displacement during the placement of the wave-damping plates, and laying a stable foundation for subsequent clamping and cutting operations. The expansion / contraction mechanism 3 is fixed inside the U-shaped frame 1 and cooperates with two sets of clamping mechanisms 2. It synchronously drives the two sets of clamping mechanisms 2 to perform converging towards the center or expanding outward within the gap between the U-shaped toothed plates 104, thus adapting to baffles of different widths without requiring replacement of clamping components, effectively improving the versatility and adaptability of the device. The clamping mechanism 2 provides stable clamping and positioning for the baffle, preventing loosening or displacement during laser cutting and ensuring overall stability of the cutting operation. The three-axis slide 102 can drive the laser cutting execution module 103 to achieve flexible multi-directional displacement, enabling it to complete the cutting operation according to the corrugated contour or even irregular structure of the baffle, improving the adaptability of the cutting operation to baffles of different structures. The laser cutting execution module 103 achieves laser cutting of the baffle by relying on the displacement of the three-axis slide 102, resulting in a more efficient cutting process, better surface flatness, and improved processing quality of the baffle.

[0028] Specifically, in this embodiment, multiple sets of funnel-shaped slag discharge ports 105 are equidistantly arranged inside the U-shaped frame 1. The lower ends of the multiple sets of slag discharge ports 105 are connected to insertion ports 109. The multiple sets of insertion ports 109 are equidistantly arranged on the lower surface of the U-shaped frame 1, and a receiving plate 106 is slidably inserted into the insertion port 109.

[0029] The funnel-shaped slag discharge port 105 within the U-shaped frame 1 effectively guides the molten slag, ensuring its rapid and smooth descent during laser cutting of the baffle plate. This prevents slag accumulation on the cutting table and baffle plate surface, minimizing its impact on the cutting operation and the baffle plate's surface quality. The connection between the slag discharge port 105 and the insertion port 109 allows the falling slag to smoothly enter the receiving carriage 106 within the insertion port 109, achieving centralized slag collection and preventing it from scattering to other parts of the equipment or the surrounding environment, thus reducing contamination and wear on surrounding components. The receiving carriage 106 and the insertion port 109 use a sliding insertion mechanism, allowing operators to easily remove the receiving carriage 106 from the insertion port 109 for slag cleaning. After cleaning, it can be quickly reset, significantly improving the convenience of slag cleaning operations. Timely collection and cleaning of molten slag can prevent molten slag from wearing down the clamping and cutting parts of the equipment, extend the service life of the relevant parts of the equipment, and at the same time prevent molten slag from contaminating the laser cutting execution module 103, ensuring that the cutting effect of the laser cutting execution module 103 remains stable.

[0030] Specifically, in this embodiment, an L-shaped limiting block 108 is fixedly installed at one end of the insertion port 109. When the receiving trolley 106 is slidably inserted into the insertion port 109 and touches one end of the L-shaped limiting block 108, the receiving compartment of the receiving trolley 106 and the slag discharge port 105 are arranged perpendicularly to each other.

[0031] The L-shaped limiting block 108 is fixed inside the insertion port 109, providing precise positioning for the insertion position of the receiving carriage 106. Operators only need to slide the receiving carriage 106 until it touches the L-shaped limiting block 108 to ensure the receiving chamber of the receiving carriage 106 is perpendicular to the slag discharge port 105, eliminating the need for additional positioning operations and improving the installation and positioning efficiency of the receiving carriage 106. This limiting method ensures that molten slag falling from the slag discharge port 105 accurately enters the receiving chamber of the receiving carriage 106, preventing slag leakage due to positioning deviations and ensuring the integrity of slag collection. Simultaneously, the L-shaped limiting block 108 keeps the receiving carriage 106 stable during equipment operation, preventing positional shifts due to vibrations from laser cutting and maintaining alignment with the slag discharge port 105, thus ensuring the stability of slag collection.

[0032] Specifically, in this embodiment, the expansion mechanism 3 includes two sets of first motors 301. The two sets of first motors 301 are fixedly installed at both ends inside the U-shaped frame 1. One end of the output shaft of each set of first motors 301 is fixedly connected to a bidirectional forward and reverse threaded screw 304. The outer surfaces of the forward and reverse threaded screw sections of the two sets of bidirectional forward and reverse threaded screws 304 are threaded with traction blocks 302. The two sets of traction blocks 302 on the outer surface of each set of bidirectional forward and reverse threaded screws 304 are rotatably connected to the lower surfaces of the two sets of clamping mechanisms 2 installed in the transmission groove 101 through a long slot 107. The long slot 107 is opened at both ends of the upper surface inside the U-shaped frame 1.

[0033] The first motor 301 provides power for the rotation of the bidirectional forward and reverse threaded rod 304, enabling the bidirectional forward and reverse rotation of the threaded rod 304. This provides a power source for the retraction and expansion of the clamping mechanism 2, automating the clamping width adjustment without manual intervention and improving the efficiency of clamping width adjustment. The structural design of the bidirectional forward and reverse threaded rod 304 allows the two sets of traction blocks 302 on its outer surface to slide synchronously towards or away from each other, ensuring that the retraction and expansion actions of the two sets of clamping mechanisms 2 remain synchronized. This ensures that both sides of the baffle plate are subjected to uniform clamping force, preventing deformation or positioning deviation of the baffle plate due to uneven force. The traction block 302 is rotatably connected to the lower surface of the clamping mechanism 2 through the elongated opening 107. The elongated opening 107 provides reasonable movement space for the traction block 302 to drive the displacement of the clamping mechanism 2, while further guiding the displacement direction of the clamping mechanism 2, preventing directional deviation during displacement. The overall transmission structure of the expansion and contraction mechanism 3 is stable, which allows for smoother displacement adjustment of the clamping mechanism 2 and ensures accurate positioning of the baffle plate. At the same time, the automated transmission method reduces manual operation steps and lowers the workload of operators.

[0034] Specifically, in this embodiment, a guide rail block 303 is fixedly installed on the upper surface of the traction block 302, and the guide rail block 303 is embedded and slidably installed in the guide rail groove opened on the lower surface of the elongated opening 107.

[0035] The guide block 303 is fixed to the upper surface of the traction block 302 and has an embedded sliding engagement with the guide groove on the lower surface of the elongated opening 107. This provides precise guidance for the sliding direction of the traction block 302, preventing it from swaying, deviating, or jamming when sliding with the bidirectional positive and negative threaded rod 304, thus ensuring the straightness of the traction block 302's sliding. The embedded sliding engagement makes the sliding process of the traction block 302 smoother, reducing wobbling during the sliding process. This, in turn, makes the displacement of the clamping mechanism 2 driven by the traction block 302 more stable, improving the accuracy of the clamping mechanism 2's position adjustment. The guide block 303 can share the force on the traction block 302 during the sliding process, reducing friction and wear between the traction block 302 and the elongated opening 107, extending the service life of both the traction block 302 and the elongated opening 107. It also reduces noise generated during the sliding process, improving the overall smoothness of the equipment's operation.

[0036] Specifically, in this embodiment, the clamping mechanism 2 includes two sets of transmission columns 201. The two sets of transmission columns 201 are rotatably disposed at both ends in the transmission groove 101, and both sets of transmission columns 201 are rotatably installed in the traction block 302 after passing through the long slot 107 through the shaft fixedly installed on their lower surface. A transmission belt 208 is fitted between the outer surfaces of the two sets of transmission columns 201. Multiple sets of guide ports 204 are opened at equal intervals on both sides of the transmission belt 208. A set of T-shaped plates 212 are slidably installed in the multiple sets of guide ports 204 on both sides of the transmission belt 208. Multiple sets of first top clamps 211 and second top clamps 210 are fixedly installed at equal intervals on one side of the two sets of T-shaped plates 212. The transmission belt 208 is fixedly connected to the T-shaped plates 212 and drives the T-shaped plates 212 to slide in the guide ports 204.

[0037] The transmission column 201 is rotatably mounted within the transmission groove 101, providing stable support for the installation and transmission of the transmission belt 208. It also allows for position adjustment as the traction block 302 slides, driving the entire clamping mechanism 2 to retract and expand, thus adapting the overall position of the clamping mechanism 2 to the width of the baffle plate. The shaft on the lower surface of the transmission column 201 passes through the elongated opening 107 and is rotatably mounted within the traction block 302. This allows the transmission column 201 to rotate without affecting its own rotation while moving with the traction block 302, ensuring the normal transmission of the transmission belt 208. The transmission belt 208 is fitted around the two sets of transmission columns 201 and, through its own transmission, drives the T-shaped plate 212 to slide within the guide opening 204. This, in turn, drives the first top clamp 211 and the second top clamp 210 to adjust their positions, providing the foundation for precise alignment of the top clamps with the corrugated grooves of the baffle plate. Guide openings 204 are equidistantly located on both sides of the transmission belt 208, guiding and limiting the sliding of the T-shaped plate 212, preventing it from swaying or falling off during sliding, and ensuring the stability and accuracy of the T-shaped plate 212's sliding. The T-shaped plate 212 provides a stable mounting base for the first clamp 211 and the second clamp 210, allowing multiple sets of clamps to adjust their positions synchronously. The equidistant installation of these clamps ensures a more uniform clamping force on the wave deflector, preventing deformation due to excessive localized stress. The first clamp 211 and the second clamp 210 can directly contact the wave deflector for clamping, conforming to the wave deflector's corrugated structure for positioning, avoiding the point contact problems of traditional planar clamping, and improving the stability of the wave deflector clamping.

[0038] Specifically, in this embodiment, the initial position of the first top clamp 211 is the top of the T-shaped plate 212 sliding in the guide opening 204, and the initial position of the second top clamp 210 is the bottom of the T-shaped plate 212 sliding in the guide opening 204, so that the first top clamp 211 and the second top clamp 210 are respectively located at the upper end and the lower end of the U-shaped toothed plate 104.

[0039] The initial position of the first clamp 211 is set at the top of the guide opening 204, and the initial position of the second clamp 210 is set at the bottom of the guide opening 204. This allows the two clamps to be positioned at the upper and lower ends of the U-shaped toothed plate 104, respectively. When adjusted from their initial positions, they can directly correspond to the upper and lower surfaces of the baffle plate, achieving initial alignment without significant adjustments and improving the alignment efficiency between the clamps and the corrugated grooves of the baffle plate. This reasonable initial position setting allows the first clamp 211 and the second clamp 210 to form a clamping structure that fits together during subsequent displacement adjustments. They press against the corrugated grooves from both the upper and lower sides of the baffle plate, ensuring that the clamping force is applied evenly from both sides. This prevents the baffle plate from warping or deforming due to unilateral force, guaranteeing the flatness of the baffle plate after clamping. Meanwhile, the initial position setting allows the adjustment range of the top clamp to match the spacing of the U-shaped toothed plate 104, preventing the top clamp from exceeding the reasonable range during adjustment and interfering with the U-shaped toothed plate 104, thus ensuring the safety of the operation of each component of the equipment.

[0040] Specifically, in this embodiment, each set of first top clamps 211 and second top clamps 210 are arranged in an alternating manner and are placed within the spacing between two adjacent sets of U-shaped toothed plates 104; the first top clamps 211 and second top clamps 210 can be adapted to the corrugated grooves on the upper and lower surfaces of the wave deflector plate respectively, and are correspondingly pressed and fitted into the corrugated grooves on the upper and lower surfaces of the wave deflector plate; when the transmission belt 208 is driven, it can drive the first top clamps 211 and second top clamps 210 to move back and forth in opposite directions respectively, and the distance of the displacement does not exceed the spacing length between two adjacent sets of U-shaped toothed plates 104; the pressing heads of the first top clamps 211 and second top clamps 210 are both integrally molded from polyurethane elastic material.

[0041] The first clamp 211 and the second clamp 210 are arranged in a staggered manner and are placed within the spacing between two adjacent sets of U-shaped toothed plates 104. This staggered arrangement allows each set of clamps to precisely correspond to the corrugated groove position of the baffle plate, enabling simultaneous pressing on multiple corrugated grooves of the baffle plate. This results in a more uniform distribution of clamping force on the baffle plate, further improving clamping stability. Placing them within the spacing of the U-shaped toothed plates 104 avoids spatial interference between the clamps and the U-shaped toothed plates 104, ensuring smooth clamp displacement and pressing action. The first clamp 211 and the second clamp 210 can be adapted to the corrugated grooves on the upper and lower surfaces of the baffle plate, respectively, and can press and fit into the corrugated grooves accordingly. This achieves surface contact clamping with the corrugated contour of the baffle plate, replacing the traditional point contact clamping method. This avoids the baffle plate shifting or loosening due to uneven force caused by point contact, improving positioning accuracy during the cutting process. The transmission belt 208 drives the first clamp 211 and the second clamp 210 to move back and forth in opposite directions, allowing the clamps to be precisely adjusted according to the actual position of the corrugated grooves of the baffle plate. This adapts to baffle plates with different corrugation spacings, further improving the device's adaptability to baffle plates of different specifications. Furthermore, the displacement distance is matched with the spacing length between the U-shaped toothed plates 104, preventing excessive clamp displacement and deviation from the reasonable working range. The pressure heads of the first clamp 211 and the second clamp 210 are integrally molded from polyurethane elastic material. This elastic material allows for a tighter fit between the clamp and the corrugated grooves of the baffle plate, improving the stability of the pressure. It also buffers the force during clamping, preventing scratches or damage to the corrugated surface of the baffle plate from the hard clamps, ensuring the surface finish of the baffle plate. The integrally molded structure makes the pressure head more robust, less prone to breakage or detachment, and effectively extends the service life of the clamps.

[0042] Specifically, in this embodiment, a first support plate 202 and a second support plate 203 are rotatably mounted between the upper and lower surfaces of the two sets of transmission columns 201, respectively. A second motor 213 is fixedly mounted on the lower inner surface of the first support plate 202, and a third motor 205 is fixedly mounted on the upper outer surface of the second support plate 203. Threaded rods are fixedly mounted on the output shafts of both the second motor 213 and the third motor 205. Push-pull blocks 206 are threadedly mounted on the outer surface of each threaded rod. The two sets of push-pull blocks 206 are slidably mounted in the sliding grooves 207 opened inside the first clamp 211 and the second clamp 210, respectively. The second motor 213 and the third motor 205 can drive the threaded rods to rotate, thereby driving the push-pull blocks 206 to push the first clamp 211 downward and pull the second clamp 210 upward, so that the two move vertically in opposite directions.

[0043] The first support plate 202 and the second support plate 203 are rotatably mounted between the upper and lower surfaces of the two sets of transmission columns 201, providing stable mounting support for the second motor 213 and the third motor 205. This ensures that the motors do not shake or shift during operation, improving their stability and guaranteeing the accuracy of subsequent pressure adjustment. The second motor 213 and the third motor 205 provide rotational power to the threaded rods on their output shafts, enabling forward and reverse rotation of the threaded rods. This, in turn, drives the push-pull block 206 to slide linearly, providing a power source for the vertical displacement of the first clamp 211 and the second clamp 210. This automates the vertical adjustment of the clamps and improves the efficiency of vertical adjustment. The threaded rod transmission method has good transmission accuracy, allowing the push-pull block 206 to slide more smoothly and avoiding sudden displacement changes, thus ensuring the accuracy of the vertical adjustment of the clamps. The push-pull block 206 is slidably installed in the sliding groove 207 inside the first top clamp 211 and the second top clamp 210. The sliding groove 207 guides and limits the sliding of the push-pull block 206, preventing it from wobbling during sliding and ensuring the precise vertical movement of the top clamps. It also allows the force of the push-pull block 206 to be smoothly transmitted to the top clamps. The second motor 213 and the third motor 205 drive the push-pull block 206 via threaded rods, pushing the first top clamp 211 downwards and pulling the second top clamp 210 upwards in a vertically opposite direction. This allows the two sets of top clamps to simultaneously press against the corrugated groove from both the upper and lower sides of the baffle plate, resulting in a more uniform pressing force. Furthermore, it allows for precise vertical adjustment based on the corrugation depth of the baffle plate, adapting to baffle plates with different corrugation depths, improving the adaptability and fit of the clamping, and preventing the baffle plate from loosening vertically during cutting.

[0044] Specifically, in this embodiment, a fourth motor 209 is fixedly installed on one end of the upper surface of the first support plate 202, and the output shaft of the fourth motor 209 is fixedly connected to one of the transmission columns 201.

[0045] The fourth motor 209 is fixedly installed on one end of the upper surface of the first support plate 202. Its output shaft is fixedly connected to one of the transmission columns 201, providing stable power for the rotation of the transmission columns 201. This enables the transmission columns 201 to rotate in both directions, thereby driving the transmission belt 208, which is fitted around the transmission columns 201, to achieve forward and reverse transmission. This provides a power source for the front-to-back displacement of the first clamp 211 and the second clamp 210, automating the adjustment of the clamps in the front-to-back direction without manual adjustment, effectively reducing the workload of the operator. The direct fixed connection between the fourth motor 209 and the transmission columns 201 makes power transmission more direct, reduces power loss during the transmission process, ensures the stability and accuracy of the rotation of the transmission columns 201, and makes the transmission of the transmission belt 208 smoother, improving the accuracy of the adjustment of the clamps' front-to-back displacement. By controlling the speed and direction of the fourth motor 209, the rotation angle of the transmission column 201 can be precisely controlled, thereby precisely controlling the transmission distance of the transmission belt 208. This enables precise control of the front and rear displacement of the first top clamp 211 and the second top clamp 210, allowing the top clamps to be more accurately aligned with the corrugated groove of the wave deflector, thus improving the overall accuracy of the wave deflector clamping and positioning.

[0046] Specifically, the laser cutting device for processing the baffle plate in this embodiment also includes a controller, which is configured to determine the vertical displacement Δz of the first clamp 211 and the second clamp 210 in the clamping mechanism 2 according to the following equation: in, Let t be the vertical distance between the first top clamp 211 and the second top clamp 210 in the initial state, t be the thickness of the baffle plate, and δ be the elastic compression of the top clamp, which is determined by the following formula: In the formula: : Cutting force acting on the baffle plate during laser cutting (unit: N); S: Preset safety factor (dimensionless, usually 1.5 to 3); L: Effective compression length of the top clamp, i.e., the height of the top clamp in the direction of force (unit: m). μ: Coefficient of friction between the top clamp and the baffle plate (dimensionless). n: The number of top clamps that simultaneously contact the baffle plate on one side (dimensionless). E: Elastic modulus of the top clamp material (unit: Pa); A: Contact area between a single top clip and the baffle plate (unit: m2).

[0047] The derivation of this equation is as follows: This equation aims to ensure that the clamping force applied by the top clamp to the baffle plate is sufficient to resist the horizontal cutting force generated during the cutting process, while avoiding damage to the baffle plate or the top clamp due to excessive clamping force. The derivation is based on the principles of mechanics of materials and static equilibrium, and the steps are as follows: Step 1: Equilibrium equation for static friction During laser cutting, the baffle plate is subjected to a horizontal cutting force. To prevent the baffle plate from slipping, the static friction force provided by the top clamps that hold it symmetrically above and below must be balanced with the cutting force.

[0048] The upper surface of the baffle plate contacts the first clamp 211, and the lower surface contacts the second clamp 210. Static friction is generated on both contact surfaces, and the total static friction is the sum of the friction forces on the upper and lower surfaces. Let the total normal force exerted by the clamp on the baffle plate by one side be N, and the coefficient of static friction between the clamp and the baffle plate be μ. Then the maximum static friction force on a single contact surface is μN, and the total static friction force is 2μN. To ensure clamping reliability, a safety factor S is introduced, and the equilibrium equation is: The minimum total normal force required to obtain the single-sided top clamp is obtained by deformation: .

[0049] Step 2: Relationship between normal force and elastic compression The total normal force N on one side is provided by n parallel clamps on the same side. The elastic compression of a single clamp is δ, and the axial compressive stiffness of a single clamp is k. According to Hooke's Law, the normal force generated by a single clamp is k·δ, and the total normal force of the n clamps on one side is: N = n·k·δ; Combining the normal force formula from step 1, we get: Step 3: Calculation of the axial stiffness of the top clamp Simplifying the top clamp as an axially loaded elastic cylinder, according to the axial compressive stiffness formula in mechanics of materials, the relationship between the stiffness k of a single top clamp and the material's elastic modulus E, contact area A, and effective compression length L is as follows: This formula conforms to the basic law of axial deformation of elastic bodies. Stiffness is positively correlated with elastic modulus and contact area, and negatively correlated with effective compression length.

[0050] Step 4: Synthesis of Elastic Compression Formula Substituting the stiffness formula into the compression formula from step 2, we obtain the final elastic compression equation: Step 5: Combining Vertical Displacement In the initial state, the vertical distance between the upper and lower clamps is The thickness of the breakwater plate is t, therefore the upper and lower clamps need to be moved towards each other first. Only then can it make perfect contact with the upper and lower surfaces of the wave deflector.

[0051] Based on this, the upper and lower clamps need to be compressed by δ respectively to generate the required normal force and static friction. Therefore, the total vertical displacement of a single clamp is: The derivation process fully considers the force characteristics, material mechanical properties, geometric parameters and safety redundancy of double-sided friction, with clear physical meaning and conforms to the actual stress conditions in engineering.

[0052] Assume the following processing parameters for a certain wave shield: Plate thickness t = 5mm = 0.005m; cutting force =200 N (estimated from laser power and material thermophysical properties); safety factor S=2; effective compression length of the top clamp L=10 mm=0.01 m; coefficient of friction μ=0.3; number of top clamps on one side n=8; elastic modulus of polyurethane top clamp E=50 MPa=5×10 7 Pa; single clamp contact area Initial vertical distance =15 mm = 0.015 m; Step 1: Calculate the elastic compression δ Substitute the parameters into the corrected δ formula: Step 2: Calculate the vertical displacement Δz .

[0053] Execution result The controller controls the second motor (213) and the third motor (205) to drive the top clamp to move 5.833mm towards each other, so as to achieve accurate and reliable clamping of the anti-wave plate, which avoids slippage and prevents damage to the workpiece and the top clamp due to excessive compression.

[0054] Parameter description table:

[0055] This equation fully considers the actual force characteristics of double-sided friction and accurately calculates the required elastic compression, ensuring that the normal pressure generated by the clamp is just right to meet the anti-slip requirements. It prevents workpiece slippage due to insufficient clamping force, and also avoids excessive clamping force exceeding the material's allowable stress, thus preventing damage to the workpiece surface and accelerated clamp wear. The precisely matched clamping force effectively suppresses vibration during the cutting process, ensuring stable processing by the laser head along the predetermined trajectory. This significantly improves the dimensional accuracy, cut smoothness, and surface quality of the baffle plate, reducing the scrap rate. The equation includes all variables such as corrugation depth, plate thickness, material properties, and the number of clamps, automatically adapting to baffle plates of different specifications and materials. Corrugated plate processing eliminates the need for repeated manual adjustments to the clamping stroke, improving equipment compatibility; it avoids excessive compression leading to premature wear of the top clamp and plastic deformation of the corrugated plate, while also reducing slag splashing and contamination of the equipment, significantly extending the replacement cycle of vulnerable parts such as the top clamp, and lowering equipment maintenance costs; combined with a controller, it achieves fully automatic calculation and adjustment of the clamping stroke, reducing manual intervention and allowing seamless integration into automated production lines, improving production efficiency and processing consistency; it retains a safety factor in its design, and through precise calculation of double-sided friction, it reduces redundant requirements on the performance of the top clamp material while ensuring clamping reliability, thus broadening the range of top clamp material options.

[0056] The working principle of this equation is as follows: 1. Parameter Input: The operator inputs the thickness t of the baffle plate, the corrugation depth (used to correct the contact area A), and the material type (automatically matching the friction coefficient μ and elastic modulus E) through the human-machine interface, and sets the safety factor S; the laser cutting execution module 103 estimates the cutting force according to the preset process parameters. Or it can be measured in real time by a force sensor.

[0057] 2. Initial positioning: The expansion mechanism 3 adjusts the clamping mechanism 2 to a suitable position according to the width of the baffle plate, so that the top clamp is roughly aligned with the corrugated groove.

[0058] 3. Horizontal alignment: The fourth motor 209 drives the transmission belt 208 to move the top clamp horizontally, so that the first top clamp 211 and the second top clamp 210 are aligned with the upper and lower corrugated grooves respectively (this can be achieved through a vision system or a preset corrugated spacing).

[0059] 4. Vertical displacement calculation: The controller calculates the required vertical displacement Δz using the corrected equation and decomposes it into the rotation of the second motor 213 and the third motor 205 (converted by lead screw).

[0060] 5. Vertical clamping: The second motor 213 and the third motor 205 operate synchronously, driving the top clamp to move towards each other to the Δz position. At this time, the top clamp is tightly attached to the baffle plate, and the elastic compression is exactly δ, generating the required clamping force.

[0061] 6. Cutting operation: The three-axis slide table 102 drives the laser cutting execution module 103 to cut along the planned path. The molten slag generated during the process falls into the receiving plate 106 through the slag discharge port 105.

[0062] 7. Unloading and Resetting: After cutting is completed, the motor moves in the opposite direction, the top clamp returns to the initial position, the finished product is taken out, and it is ready for the next processing cycle.

[0063] Through the above process, the corrected equation becomes the core algorithm for the intelligent control of the device, realizing fully automated, high-precision clamping and cutting of the baffle plate.

[0064] Overall working principle of this device: This device uses the U-shaped frame 1 as the basic support carrier. Through the coordinated operation of the expansion and contraction mechanism 3, the clamping mechanism 2, the laser cutting mechanism, and the slag removal mechanism, it achieves automated and precise clamping and laser cutting of the baffle plate, while simultaneously completing the centralized collection of molten slag. The transmission and coordination principles of each mechanism are as follows: 1. Transmission principle of the contraction and expansion mechanism 3: Two sets of first motors 301 serve as power sources, driving the bidirectional forward and reverse threaded rods 304 to rotate in opposite directions, causing the two sets of traction blocks 302 on their outer surfaces to slide synchronously towards or away from each other along the threaded rods. The guide block 303 is embedded in the guide groove on the lower surface of the elongated opening 107, providing guidance and limiting for the sliding of the traction block 302 to avoid sliding deviation. The traction block 302 is rotatably connected to the transmission column 201 of the clamping mechanism 2 through the elongated opening 107, thereby driving the two sets of clamping mechanisms 2 to synchronously contract towards the center or expand outward within the gap between the U-shaped toothed plates 104, realizing the automatic adjustment of the clamping width and adapting to the anti-wave plates of different widths.

[0065] 2. Precise pressing principle of clamping mechanism 2: The fourth motor 209 drives the transmission column 201 to rotate, which drives the transmission belt 208 mounted on the two sets of transmission columns 201 to drive, and then drives the T-shaped plate 212 in the guide openings 204 on both sides of the transmission belt 208 to move back and forth in opposite directions, so that the first clamp 211 and the second clamp 210 installed on the T-shaped plate 212 are precisely aligned with the corrugated grooves on the upper and lower surfaces of the baffle plate; at the same time, the second motor 213 and the third motor 205 drive the threaded rod on their output shaft to rotate, which drives the push-pull block 206 threaded on the threaded rod to slide along the sliding groove 207, thereby pushing the first clamp 211 downward and pulling the second clamp 210 upward to move vertically in opposite directions. Combined with the staggered arrangement of the first clamp 211 and the second clamp 210, they are precisely fitted and pressed into the corrugated grooves on the upper and lower surfaces of the baffle plate to achieve a stable surface contact clamping. The pressure head made of polyurethane elastic material can also ensure tight fit and avoid damage to the surface of the baffle plate.

[0066] 3. Transmission principle of laser cutting: The three-axis slide table 102 on the upper surface of the U-shaped frame 1 can drive the laser cutting execution module 103 to achieve flexible displacement in the X, Y and Z directions. According to the corrugated contour of the baffle plate and the requirements of irregular processing, the position and angle of the laser cutting execution module 103 are adjusted to complete the precise laser cutting operation.

[0067] 4. Working principle of slag collection: The spacing between the U-shaped toothed plates 104 provides a falling channel for the slag. The slag generated by laser cutting falls through this spacing to the funnel-shaped slag discharge port 105 in the U-shaped frame 1. The slag discharge port 105 guides the slag, allowing it to fall smoothly into the receiving carriage 106 in the insertion port 109. The L-shaped limiting block 108 limits the insertion position of the receiving carriage 106, ensuring that the receiving chamber of the receiving carriage 106 is perpendicular to the slag discharge port 105, thereby achieving accurate collection of slag and preventing slag leakage.

[0068] How to use: 1. Loading and positioning: Place the corrugated baffle plate to be processed on multiple sets of U-shaped toothed plates 104 in the U-shaped frame 1. Use the U-shaped toothed plates 104 to provide initial support and auxiliary positioning for the baffle plate to avoid positional displacement during the placement stage.

[0069] 2. Preliminary clamping width adjustment: Start the two sets of first motors 301 to drive the bidirectional positive and negative threaded screws 304 to rotate, which in turn drives the two sets of traction blocks 302 to slide towards each other along the screws. This causes the two sets of clamping mechanisms 2 to move closer to the center within the gap between the U-shaped toothed plates 104 until the clamping mechanisms 2 are initially in contact with the two sides of the baffle plate. At the same time, the baffle plate is pushed to the center position of the U-shaped toothed plate 104 to complete the center positioning before cutting and adapt to the width specifications of the baffle plate.

[0070] 3. Precise top-press clamping of corrugated grooves: Start the fourth motor 209 to drive the transmission column 201 to rotate and drive the transmission belt 208 to move the first clamp 211 and the second clamp 210 back and forth in opposite directions, precisely aligning them with the corrugated grooves on the upper and lower surfaces of the baffle plate; at the same time, start the second motor 213 and the third motor 205 to drive the threaded rod to rotate and drive the push-pull block 206 to slide, so that the first clamp 211 moves downward and the second clamp 210 moves upward in opposite directions vertically until the two sets of clamps are precisely attached and pressed into the corrugated grooves on the upper and lower surfaces of the baffle plate, completing the stable clamping of the baffle plate and avoiding displacement during the cutting process.

[0071] 4. Laser cutting operation: Start the three-axis slide 102 and the laser cutting execution module 103. The three-axis slide 102 drives the laser cutting execution module 103 to move flexibly in the X, Y and Z directions. In accordance with the corrugated contour and irregular shape processing requirements of the baffle plate, the laser cutting operation of the baffle plate is completed. The molten slag generated during the cutting process falls through the gap between the U-shaped toothed plates 104 and is collected by the slag discharge mechanism.

[0072] 5. Release clamping and unloading: After cutting, turn off the laser cutting execution module 103 and the three-axis slide table 102. First, start the second motor 213 and the third motor 205 to rotate in opposite directions, driving the push-pull block 206 to slide in opposite directions, so that the first clamp 211 and the second clamp 210 move vertically in opposite directions, releasing the pressure on the upper and lower surfaces of the baffle plate. Then, start the fourth motor 209 to rotate in opposite directions, driving the transmission belt 208 to drive in opposite directions, so that the clamps move in opposite directions away from the baffle plate. Finally, start the two sets of first motors 301 to rotate in opposite directions, driving the bidirectional positive and negative threaded rods 304 to rotate in opposite directions, driving the traction block 302 to slide in opposite directions, so that the two sets of clamping mechanisms 2 expand outward, completely releasing the clamping of the baffle plate, and the operator can take out the processed baffle plate.

[0073] 6. Slag Cleaning: When a certain amount of slag is collected in the receiving carriage 106, the receiving carriage 106 is pulled out from the insertion port 109, and the collected slag is cleaned in a concentrated manner. After cleaning, the receiving carriage 106 is slid back into the insertion port 109 and touches the L-shaped limiting block 108, so that the receiving chamber and the slag discharge port 105 are perpendicular to each other, completing the reset of the receiving carriage 106 and preparing for the collection of slag in the next cutting operation.

[0074] Overall technical effect: 1. Improved clamping adaptability and versatility: The retraction and expansion mechanism 3 drives the bidirectional forward and reverse threaded rod 304 through the first motor 301 to synchronously retract or expand the clamping mechanism 2, realizing automatic adjustment of the clamping width, which can adapt to baffles of different widths; the clamping mechanism 2 realizes bidirectional displacement adjustment of the first top clamp 211 and the second top clamp 210 in front-back and vertical directions through the coordinated control of the fourth motor 209, the second motor 213 and the third motor 205, which can adapt to baffles of different corrugation spacing and different corrugation depths. There is no need to replace the clamping components, which greatly improves the adaptability and versatility of the device to baffles of different specifications and solves the problem of poor versatility of traditional devices.

[0075] 2. Achieving precise and stable clamping of the baffle plate: The U-shaped toothed plate 104 provides initial support and center positioning for the baffle plate. The first clamp 211 and the second clamp 210 of the clamping mechanism 2 are arranged in an alternating manner and can accurately fit and press against the corrugated grooves on the upper and lower surfaces of the baffle plate, achieving surface contact clamping, which replaces the traditional point contact clamping method. This avoids the baffle plate from shifting or loosening due to uneven force, and the vibration during the cutting process will not affect the positioning accuracy, ensuring the stability and precision of the baffle plate clamping.

[0076] 3. Improve the automation and efficiency of cutting operations: This device achieves fully automated operation of clamping width adjustment, precise corrugated groove pressing, and cutting head displacement adjustment through the linkage control of various motors. It eliminates the need for manual adjustment of the components for clamping and positioning, greatly reducing manual operation steps and the workload of operators. At the same time, it improves the overall efficiency of baffle clamping and cutting, and solves the problem of low adjustment efficiency of traditional devices.

[0077] 4. Ensure the surface quality of the baffle plate: The top pressure heads of the first top clamp 211 and the second top clamp 210 are integrally molded from polyurethane elastic material. The elastic material allows the top clamp to fit more tightly with the corrugated groove of the baffle plate, while buffering the force during clamping and avoiding scratches or pressure damage to the corrugated surface of the baffle plate caused by the hard top clamp, thus ensuring the surface processing quality of the baffle plate after cutting.

[0078] 5. Achieve centralized slag collection, protect equipment and reduce maintenance costs: The spacing design of the U-shaped toothed plate 104, combined with the funnel-shaped slag discharge port 105, guides the cutting slag to fall quickly and smoothly, preventing slag accumulation on the cutting table and baffle plate surface; the L-shaped limiting block 108 ensures precise alignment between the receiving plate 106 and the slag discharge port 105, achieving precise slag collection, preventing slag leakage to other parts of the equipment, preventing slag from wearing down the clamping components of the equipment and contaminating the laser cutting execution module 103, ensuring the cutting effect of the laser cutting execution module 103 remains stable, while reducing the probability of equipment failure, extending the service life of various components of the equipment, and reducing equipment maintenance costs.

[0079] 6. Improved cutting accuracy and processing quality: The three-axis slide 102 drives the laser cutting execution module 103 to achieve flexible multi-directional displacement, which can accurately match the corrugated contour and irregular structure of the wave deflector to complete the cutting operation. Combined with the stable clamping effect of the wave deflector, the problem of wave deflector displacement during the cutting process is avoided, which greatly improves the cutting accuracy of the wave deflector and ensures the overall processing quality of the wave deflector, meeting the processing requirements of the shipbuilding, marine engineering and other industries for wave deflectors.

[0080] 7. Ensuring the stability and smoothness of equipment operation: The embedded sliding fit between the guide rail block 303 and the guide rail groove provides guidance and limit for the sliding of the traction block 302, preventing sliding deviation or jamming; the guide port 204 limits the sliding of the T-shaped plate 212, and the sliding groove 207 guides the sliding of the push-pull block 206. The limit and guide design of each component makes the transmission process of the device smoother, reduces friction and wear between components, reduces noise during equipment operation, and ensures the overall stability and smoothness of equipment operation.
