Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, specifically to an automated sheet metal cutting device for shipbuilding and repair. Background Technology

[0002] Automated plate cutting equipment for shipbuilding and repair is a device used to automatically cut plates required in ship construction. This device typically consists of a CNC cutting machine and related software systems. It can accurately cut plates of various shapes and sizes according to design drawings and requirements to meet the needs of shipbuilding. This equipment can improve production efficiency, reduce manual operation, and ensure the accuracy and quality of cutting.

[0003] According to the search, a patent publication number CN221848867U for an automated plate cutting device for ship repair and construction was published in China on October 18, 2024. It is roughly described as including: a frame mechanism, the frame mechanism including a placement frame, a base plate on the placement frame, and a connecting plate between the base plate and the placement frame.

[0004] While the aforementioned existing technical solution can more conveniently cut the sheet material and is easier to use, the device cannot position the sheet material to be cut, which can easily lead to skewed cutting position and reduce cutting effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an automated plate cutting device for shipbuilding and repair, which solves the problem mentioned in the background technology that the plate to be cut cannot be positioned, which easily leads to the cutting position being skewed and reduces the cutting effect.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automated plate cutting device for shipbuilding and repair, comprising a workbench and a base plate. Support legs are fixedly connected to the four corners of the top of the base plate. The workbench is fixedly connected to the top of the four support legs. A cutting opening is provided on the workbench. A mounting plate is rotatably connected to the bottom of the workbench. A first motor is mounted on the mounting plate. The output end of the first motor passes through the mounting plate and is connected to a cutting blade that mates with the cutting opening. An electric push rod is rotatably connected to the top of the base plate. The top of the electric push rod is rotatably connected to the mounting plate. Two matching control slots are provided at the top of the workbench. Threaded rods are rotatably connected inside each of the two control slots. Threaded components that pass through the control slots are threaded onto the threaded rods. A positioning plate is fixedly connected between the two threaded components. One end of each of the two threaded rods passes through the control slot and is connected to a sprocket. A chain is drivingly connected between the two sprockets. A mounting frame is fixedly connected to one end of the workbench. A servo motor connected to the sprockets is mounted on the mounting frame. A self-adjusting chain tensioner that mates with the chain is mounted on the workbench.

[0009] By adopting the above technical solution, the sheet material is placed on the worktable. The servo motor is then activated to drive the sprockets and chain to rotate. A self-adjusting chain tensioner keeps the chain taut, causing the two sprockets to drive the two threaded rods to rotate synchronously. These two threaded rods then move the threaded components, thereby moving the positioning plate. The distance between the positioning plate and the cutting blade is adjusted according to the desired cutting position on the sheet material, ensuring one end of the sheet material is flush with the positioning plate. The electric push rod is then activated to rotate the mounting plate, allowing one end of the cutting blade to pass through the cutting kerf and cut the sheet material. The sheet material can be pushed to ensure precise cutting, facilitating accurate positioning and preventing skewing, thus improving the cutting effect.

[0010] Optionally, both control slots have discharge channels on their inner lower sidewalls.

[0011] By adopting the above technical solution, when the equipment cuts the plate, it is easy to generate waste chips, which can easily splash into the control groove. The discharge groove is used to facilitate the discharge of waste chips that splash into the control groove, so that the waste chips are discharged out of the control groove, avoiding the waste chips from affecting the movement of the threaded parts, and achieving the purpose of improving the stability of the equipment.

[0012] Optionally, the top of the worktable is provided with a scale that mates with the positioning plate.

[0013] By adopting the above technical solution, the scale is used to indicate the current position of the positioning plate. When the length of the material to be cut is known, the positioning plate can be adjusted more conveniently, thereby improving work efficiency.

[0014] Optionally, the top of the workbench is provided with an inclined baffle, and the sprocket and chain are both located below the inclined baffle.

[0015] By adopting the above technical solution, the inclined baffle is used to shield the sprocket and chain, preventing flying debris from falling onto the chain and causing damage to the chain and sprocket, leading to chain derailment, thereby improving the stability of the equipment.

[0016] Optionally, a limiting component is fixedly connected to one end of the mounting plate, and two limiting holes are provided on the limiting component. Two arc-shaped limiting rods are fixedly connected between the worktable and the base plate, and the two arc-shaped limiting rods are slidably connected to the two limiting holes respectively.

[0017] By adopting the above technical solution, the limiting hole is used to facilitate the sliding of the limiting component along the arc-shaped limiting rod, so that the limiting component cooperates with the arc-shaped limiting rod to limit the mounting plate, thereby preventing the mounting plate from shaking or deviating, and thus preventing the cutting blade from shaking or deviating, thereby improving the stability of the equipment.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] The automated plate cutting device for ship repair and construction places the plate on the worktable. A servo motor is then activated, driving the sprockets and chain to rotate. A self-adjusting chain tensioner keeps the chain taut, causing two sprockets to drive two threaded rods to rotate synchronously. These rods then move threaded components, which in turn move a positioning plate. The distance between the positioning plate and the cutting blade is adjusted according to the desired cutting position on the plate, ensuring one end of the plate is flush against the positioning plate. An electric push rod is then activated, rotating the mounting plate and allowing one end of the cutting blade to pass through the cutting slit, enabling the blade to cut the plate. The plate can be pushed to ensure precise cutting, facilitating accurate plate positioning, preventing cutting deviations, and improving cutting efficiency. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-4An automated plate cutting device for shipbuilding and repair includes a workbench 1 and a base plate 2. Support legs 3 are fixedly connected to the four corners of the top of the base plate 2. The workbench 1 is fixedly connected to the top of the four support legs 3. A cutting opening 4 is provided on the workbench 1. A mounting plate 5 is rotatably connected to the bottom of the workbench 1. A first motor 6 is mounted on the mounting plate 5. The output end of the first motor 6 passes through the mounting plate 5 and is connected to a cutting blade 7 that mates with the cutting opening 4. An electric push rod 8 is rotatably connected to the top of the base plate 2. The top of the electric push rod 8 is rotatably connected to the mounting plate 5. Two mating control slots 9 are provided at the top of the workbench 1. Threaded rods 10 are rotatably connected inside each of the two control slots 9. Threaded parts 11 that penetrate the control slots 9 are threaded onto the threaded rods 10. A positioning plate 12 is fixedly connected between the two threaded parts 11. One end of each threaded rod 10 passes through the control slots 9 and is connected to a sprocket 13. A chain 14 drives between the two sprockets 13. A mounting frame 15 is fixedly connected to one end of the workbench 1. A servo motor 16 connected to a sprocket 13 is installed. A self-adjusting chain tensioner for the chain 14 is installed on the worktable 1. When the board is placed on the worktable 1, the servo motor 16 is started to drive the sprocket 13 and the chain 14 to rotate. The self-adjusting chain tensioner keeps the chain 14 taut, so that the two sprockets 13 drive the two threaded rods 10 to rotate synchronously. The two threaded rods 10 drive the threaded parts 11 to move synchronously, thereby moving the positioning plate 12. The distance between the positioning plate 12 and the cutting blade 7 is adjusted according to the position to be cut on the board. At this time, one end of the board can be pressed tightly against the positioning plate 12. Then, the electric push rod 8 is started to drive the mounting plate 5 to rotate, so that one end of the cutting blade 7 passes through the cutting opening 4, so that the cutting blade 7 cuts the board. The board can be pushed to make the cutting blade 7 cut the board precisely, which facilitates the positioning of the board and avoids the cutting position from deviating, thereby improving the cutting effect.

[0030] Reference Figure 4 and Figure 5 Both control slots 9 have discharge channels 17 on their inner lower side walls. When the equipment cuts the plate, waste chips are easily generated, which can easily splash into the control slots 9. The discharge channels 17 are used to facilitate the discharge of waste chips that splash into the control slots 9, so that the waste chips can be discharged out of the control slots 9, avoiding the waste chips from affecting the movement of the threaded parts 11, and thus improving the stability of the equipment.

[0031] Reference Figure 3 The top of the workbench 1 is provided with a scale 18 that cooperates with the positioning plate 12. The scale 18 is used to indicate the current position of the positioning plate 12. When the length of the material to be cut is known, the positioning plate 12 can be adjusted more conveniently, thereby improving work efficiency.

[0032] Reference Figures 1-3 The top of the workbench 1 is provided with an inclined baffle 19. The sprocket 13 and the chain 14 are both located below the inclined baffle 19. The inclined baffle 19 is used to shield the sprocket 13 and the chain 14 to prevent flying debris from falling onto the chain 14, which would affect the chain 14 and the sprocket 13 and cause the chain to derail, thereby improving the stability of the equipment.

[0033] Reference Figure 1 and Figure 4 One end of the mounting plate 5 is fixedly connected to a limiting component 20, which has two limiting holes. Two arc-shaped limiting rods 21 are fixedly connected between the worktable 1 and the base plate 2. The two arc-shaped limiting rods 21 are slidably connected to the two limiting holes respectively. The limiting holes are used to facilitate the sliding of the limiting component 20 along the arc-shaped limiting rods 21, so that the limiting component 20 and the arc-shaped limiting rods 21 cooperate to limit the mounting plate 5, thereby preventing the mounting plate 5 from shaking or tilting, and thus preventing the cutting blade 7 from shaking or tilting, thereby improving the stability of the equipment.

[0034] In summary, the working principle and process of the automated plate cutting device for shipbuilding and repair are as follows: First, the plate is placed on the worktable 1. Then, the servo motor 16 is activated, driving the sprocket 13 and chain 14 to rotate. A self-adjusting chain tensioner keeps the chain 14 taut, causing the two sprockets 13 to drive the two threaded rods 10 to rotate synchronously. The two threaded rods 10 then synchronously drive the threaded parts 11 to move, thereby moving the positioning plate 12. The distance between the positioning plate 12 and the cutting blade 7 is adjusted according to the desired cutting position on the plate, ensuring one end of the plate is flush with the positioning plate 12. Next, the electric push rod 8 is activated, driving the mounting plate 5 to rotate, allowing one end of the cutting blade 7 to pass through the cutting opening 4, thus enabling the cutting blade 7 to cut the plate. The plate can be pushed to ensure precise cutting by the cutting blade 7, facilitating plate positioning, preventing cutting deviation, and improving cutting efficiency. During cutting, waste chips are easily generated, which can easily splash into the control groove 9. The discharge groove 17 is used to facilitate the discharge of waste chips that splash into the control groove 9, allowing the waste chips to be discharged out of the control groove 9 and preventing the waste chips from affecting the movement of the threaded part 11, thereby improving the stability of the equipment. The scale 18 is used to indicate the current position of the positioning plate 12. When the length of the plate to be cut is known, the positioning plate 12 can be adjusted more conveniently, thereby improving work efficiency. The inclined baffle plate 19 is used to shield the sprocket 13 and the chain 14, preventing the splashed waste chips from falling onto the chain 14 and affecting the chain 14 and sprocket 13, causing the chain to derail, thereby improving the stability of the equipment. The limiting hole is used to facilitate the sliding of the limiting part 20 along the arc-shaped limiting rod 21, so that the limiting part 20 cooperates with the arc-shaped limiting rod 21 to limit the mounting plate 5, thereby preventing the mounting plate 5 from shaking or tilting, and thus preventing the cutting blade 7 from shaking or tilting, thereby improving the stability of the equipment.

[0035] The above-described embodiments merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
