Technical Field
[0001] The present invention relates to the technical field of arc cutting devices, and particularly to an arc cutting device for deck outfitting parts and a cutting method thereof. Background Art
[0002] In the field of shipbuilding and ocean engineering, the manufacturing and installation of deck outfitting parts (such as pipe supports, cable trays, guardrails, steel plate decks, etc.) are one of the core links. These components are usually made of high-strength steel, alloys or other metal materials, and need to be precisely cut, welded and assembled according to the deck layout. In traditional metal cutting processes, although flame cutting, mechanical shearing and laser cutting are widely used, they still have problems such as low efficiency, high cost or insufficient adaptability in specific scenarios. Arc cutting technology has gradually become an important choice for deck outfitting part processing due to its simple equipment, low cost and suitability for thick plate materials. However, the existing arc cutting devices for deck outfitting parts such as steel plate decks still face the following technical problems in the deck outfitting scenario: When the existing equipment cuts a steel plate deck, it mostly uses a handheld or semi-fixed design to fix the steel plate deck during cutting, lacking stable path planning and adaptive control functions. When cutting the outfitting parts of the steel plate deck, it is necessary to frequently adjust the position of the steel plate deck, making it difficult to achieve continuous batch processing, increasing labor costs and safety hazards, resulting in low efficiency. At the same time, the high-temperature spatter, metal dust and harmful gases generated during the arc cutting process seriously pollute the cutting operation space environment, and manual operation causes serious damage to the surrounding workers.

[0014] A cutting method of the arc cutting device for deck outfitting comprises the following steps: S1, placing the deck outfitting to be cut on the conveying rollers, and intermittently conveying the deck outfitting on the conveying rollers by intermittently rotating a plurality of conveying rollers; S2, during the intermittent conveying process on the conveyor roller, the deck outfitting will repeatedly move forward a short distance and then stop for a period of time. When the deck outfitting is still, the arc cutting gun is started to perform arc cutting on the deck outfitting; S3, during the intermittent conveying process on the conveyor roller, the deck outfitting will repeatedly be conveyed forward for a short distance and then remain stationary for a period of time. In conjunction with the reciprocating movement of the clamping plate on the conveyor roller, when the deck outfitting is stationary and arc cutting is being performed, the clamping plate moves to both sides of the deck outfitting to clamp and fix the deck outfitting during cutting. Afterwards, when the clamping plate moves away from both sides of the deck outfitting and releases the fixation on both sides of the deck outfitting, the deck outfitting continues to be conveyed forward on the conveyor roller.

The third toothed belt pulley is arranged on the first rotating shaft. The first rotating shaft and the second rotating shaft are cooperatively connected through an intermittent mechanism. When the second rotating shaft rotates, it will drive the first rotating shaft to rotate intermittently. The intermittent rotation of the first rotating shaft will drive the third toothed belt pulley to rotate intermittently, thereby driving the plurality of conveying rollers to rotate intermittently, and thus driving the deck outfitting parts on the conveying rollers to be intermittently conveyed; Two clamping plates for clamping and fixing both sides of the deck outfitting parts are slidably arranged on the conveying rollers. A fourth rotating shaft is rotatably arranged on the frame. When the second rotating shaft rotates, it will drive the fourth rotating shaft to rotate clockwise and counterclockwise reciprocally. When the fourth rotating shaft rotates clockwise and counterclockwise reciprocally, it will drive the clamping plates to reciprocally move on the conveying rollers.
[0016] Therefore, during the intermittent conveying of the deck outfitting parts on the conveying rollers in the present invention, the action of repeatedly conveying forward a small distance and then staying still for a period of time will be repeated. Combining with the action of the clamping plates reciprocally moving on the conveying rollers, when the deck outfitting parts stay still and are subjected to arc cutting, the clamping plates move to both sides of the deck outfitting parts to clamp and fix them during cutting. After the clamping plates move away from both sides of the deck outfitting parts to release the fixation on both sides of the deck outfitting parts, the deck outfitting parts on the conveying rollers continue to move forward. Thus, the present invention can realize the continuous cutting operation of the automated stable path conveying of deck outfitting parts, can be used for the continuous batch cutting and processing of deck outfitting parts, reduces the labor cost and potential safety hazards, and effectively improves the cutting efficiency.

[0030] In this embodiment, when in use, the steel plate deck outfitting to be cut is placed on the conveying roller 3, and the steel plate deck outfitting on the conveying roller 3 is intermittently conveyed by the intermittent rotation of multiple conveying rollers 3. Two clamping plates 33 for clamping and fixing the steel plate deck outfitting on both sides are slidably provided on the conveying roller 3. A first rotating shaft 14 and a second rotating shaft 15 are rotatably provided on the base frame 1. The third toothed pulley 13 is provided on the first rotating shaft 14. The first rotating shaft 14 and the second rotating shaft 15 are connected by an intermittent mechanism. When the second rotating shaft 15 rotates, it drives the first rotating shaft 14 to rotate intermittently. A fourth rotating shaft 26 is rotatably provided on the frame 2.

In coordination with the reciprocating movement of the clamping plate 33 on the conveyance roller 3, when the steel plate deck fitting is stationary and arc cutting is performed, the clamping plate 33 moves to both sides of the steel plate deck fitting to clamp and fix it during cutting. After that, when the clamping plate 33 moves away from both sides of the steel plate deck fitting to release the fixation on both sides of the steel plate deck fitting, the steel plate deck fitting on the conveyance roller 3 continues to convey forward.
[0031] As a further solution of the present invention, guide plates 4 for limiting both sides of the deck fitting during conveyance on the conveyance roller 3 are respectively arranged at both ends of the conveyance roller 3.
[0032] In this embodiment, after the deck fitting is placed on the conveyance roller 3, the guide plates 4 at both ends of the conveyance roller 3 can limit both sides of the deck fitting, which is beneficial for guiding and conveying the deck fitting on the conveyance roller 3.
[0033] As a further solution of the present invention, a bracket 6 is arranged on the frame 2, a first guide rail 7 is arranged on the bracket 6, a first slider 8 is slidably clamped on the first guide rail 7, a second guide rail 9 is arranged on the first slider 8, a second slider 10 is slidably clamped on the second guide rail 9, and the arc cutting gun 5 is installed on the second slider 10.
[0034] In this embodiment, the first slider 8 can be slidably adjusted on the first guide rail 7. The second guide rail 9 is arranged on the first slider 8 so that the second guide rail 9 can be horizontally moved and adjusted. The second slider 10 can be slidably adjusted on the second guide rail 9. The arc cutting gun 5 is arranged on the second slider 10. Thus, the arc cutting gun 5 can be adjusted in the vertical position. Therefore, by sliding the first slider 8 on the first guide rail 7 and the second slider 10 on the second guide rail 9, the horizontal position and height of the arc cutting gun 5 can be adjusted to meet the requirements of the arc cutting gun 5 for cutting different positions of the deck fitting.
[0035] As a further solution of the present invention, a motor 16 is installed on the chassis 1, and the second rotating shaft 15 is installed at the output end of the motor 16 and driven to rotate by the motor 16.
[0036] In this embodiment, the motor 16 is electrically connected to an external power supply through a wire. When the motor 16 is started, the motor 16 can drive the second rotating shaft 1 to rotate.
[0037] As a further solution of the present invention, the intermittent mechanism includes a driven wheel 17 arranged on the first rotating shaft 14 and a driving wheel 18 arranged on the second rotating shaft 15, and the driven wheel 17 is in transmission connection with the driving wheel 18.
[0038] In this embodiment, when the second rotating shaft 15 rotates, it will drive the driving wheel 18 to rotate synchronously. The transmission connection between the driven wheel 17 and the driving wheel 18 can drive the driven wheel 17 to rotate intermittently. When the driven wheel 17 rotates, it will drive the first rotating shaft 14 to rotate, so that when the second rotating shaft 15 rotates, it will drive the first rotating shaft 14 to rotate intermittently. When the first rotating shaft 14 rotates, it will drive the third toothed belt pulley 13 to rotate. The first toothed belt pulley 11, the second toothed belt pulley 12, and the third toothed belt pulley 13 are connected by the toothed belt 34 to drive the multiple first toothed belt pulleys 11 to rotate, thereby driving the multiple conveying rollers 3 to rotate, so that the rotation of the second rotating shaft 15 drives the multiple conveying rollers 3 to rotate intermittently.
[0039] As a further solution of the present invention, the first linkage structure includes a third rotating shaft 19 rotatably arranged on the base frame 1, and the third rotating shaft 19 is connected to the second rotating shaft 15 through a gear transmission mechanism. A first turntable 22 is provided on the third rotating shaft 19, and a second turntable 27 is provided on the fourth rotating shaft 26. A swing arm 24 is provided between the first turntable 22 and the second turntable 27. One end of the swing arm 24 is hinged to the second turntable 27, and the other end is provided with a through slot 25. The first turntable 22 is provided with a protruding rod 23 that is movably engaged with the inside of the through slot 25.
[0040] In this embodiment, when the second rotating shaft 15 rotates, the third rotating shaft 19 is driven to rotate by the transmission connection between the third rotating shaft 19 and the second rotating shaft 15 through the gear transmission mechanism. When the third rotating shaft 19 rotates, it will drive the first turntable 22 to rotate, and then drive the protruding rod 23 to rotate and slide in the through groove 25, thereby driving the swing arm 24 to swing back and forth. The reciprocating swing of the swing arm 24 drives the second turntable 27 to rotate back and forth clockwise and counterclockwise, and then drives the fourth rotating shaft 26 to rotate back and forth clockwise and counterclockwise.
[0041] It should be noted that a stop block is provided at the bottom end of the protruding rod 23 , the outer dimensions of the stop block are adapted to the inner dimensions of the through slot 25 , and the stop block is used to prevent the protruding rod 23 from falling out of the through slot 25 .

[0044] As a further solution of the present invention, the second linkage structure includes a third turntable 28 provided on the fourth rotating shaft 26 and a cylinder 29 provided on the frame 2. An articulated rod 32 is articulated on the third turntable 28. One end of the articulated rod 32 is articulated with a connecting rod 31 that is movably inserted into the interior of the cylinder 29. A movable slider 30 that is movably clamped inside the cylinder 29 is provided on the connecting rod 31. The clamping plate 33 is fixed to the movable slider 30 through the connecting rod.
[0045] In this embodiment, when the fourth rotating shaft 26 rotates reciprocally clockwise and counterclockwise, it will drive the third turntable 28 to rotate reciprocally clockwise and counterclockwise, thereby driving the articulated rod 32 to reciprocally swing, dragging the movable slider 30 at one end of the connecting rod 31 to reciprocally move inside the cylinder 29. The clamping plate 33 is arranged on the movable slider 30. Therefore, when the fourth rotating shaft 26 rotates reciprocally clockwise and counterclockwise, it will drive the clamping plate 33 to reciprocally move horizontally. When the two clamping plates 33 approach each other, they clamp and fix the deck outfitting parts. When the two clamping plates 33 move away from each other, the clamping of both sides of the deck outfitting parts is released.
[0046] As a further solution of the present invention, a U-shaped groove 37 is formed on the clamping plate 33. An extrusion plate 36 is movably clamped inside the toothed belt 34. A spring 35 is arranged on the inner wall of the U-shaped groove 37. Both ends of the spring 35 are fixedly connected to the extrusion plate 36 and the inner wall of the U-shaped groove 37 respectively.
[0047] In this embodiment, by forming a U-shaped groove 37 on the clamping plate 33, when the clamping plate 33 clamps and fixes both sides of the deck outfitting parts, both sides of the deck outfitting parts will be clamped inside the U-shaped groove 37. The extrusion plate 36 laterally extrudes it, and the upper and lower walls of the U-shaped groove 37 synchronously limit and fix it vertically. Moreover, the spring 35 can elastically expand and contract. When the extrusion plate 36 extrudes and fixes both sides of the deck outfitting parts, it can also displace simultaneously, ensuring that the clamping plate 33 can slide on the conveying roller 3.
[0048] During use, the steel plate deck outfitting parts to be cut are placed on the conveying roller 3, and the steel plate deck outfitting parts on the conveying roller 3 are intermittently conveyed through the intermittent rotation of multiple conveying rollers 3. Two clamping plates 33 for clamping and fixing both sides of the steel plate deck outfitting parts are slidably arranged on the conveying roller 3. A first rotating shaft 14 and a second rotating shaft 15 are rotatably arranged on the chassis 1. A third toothed belt pulley 13 is arranged on the first rotating shaft 14. The first rotating shaft 14 and the second rotating shaft 15 are connected in cooperation through an intermittent mechanism. When the second rotating shaft 15 rotates, it will drive the first rotating shaft 14 to rotate intermittently. A fourth rotating shaft 26 is rotatably arranged on the frame 2. When the second rotating shaft 15 rotates, it will drive the fourth rotating shaft 26 to rotate reciprocally clockwise and counterclockwise. When the fourth rotating shaft 26 rotates reciprocally clockwise and counterclockwise, it will drive the clamping plate 33 to reciprocally move on the conveying roller 3; During the intermittent conveying process of the steel plate deck fitting on the conveying roller 3, it will repeat the actions of conveying forward a short distance and then remaining stationary for a period of time. When the steel plate deck fitting is stationary, the arc cutting gun 5 is activated to perform arc cutting on the steel plate deck fitting. During the intermittent conveying process of the steel plate deck fitting on the conveying roller 3, it will repeat the actions of conveying forward a short distance and then remaining stationary for a period of time, and cooperate with the reciprocating movement of the clamping plate 33 on the conveying roller 3. When the steel plate deck fitting is stationary and arc cutting is being performed, the clamping plate 33 moves to both sides of the steel plate deck fitting to clamp and fix it during cutting. After that, when the cutting is completed and the clamping plate 33 moves away from both sides of the steel plate deck fitting to release the fixation on both sides of the steel plate deck fitting, the steel plate deck fitting on the conveying roller 3 continues to convey forward, and the above actions are repeated to complete the continuous conveying and cutting operations of the deck fitting.
[0049] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
