Description

Technical Field

[0001] The invention relates to the technical field of deck welding processing, in particular to a positioning device for deck welding. Background Art

[0002] The deck of a ship is the plane with the largest area on the hull, mainly referring to the supporting layer. The support here refers to supporting cargo or people. At the same time, the deck also plays an important role in strengthening the hull structure and facilitating layered loading and loading, ensuring the strength and unsinkability of the hull.

[0003] 1. The existing process relies on manual pushing of the deck to slide on the welding table and manual alignment of the edges. The lack of an automated alignment mechanism makes fine-tuning difficult, affecting welding accuracy. Gap control relies on manual visual inspection and manual adjustment, making it difficult to quickly set and control precise gap widths.

[0004] 2. The traditional exhaust fan is arranged at the far end of the welding table, and the negative pressure area formed is insufficiently covered, resulting in low smoke capture efficiency and high requirements for fan power. The smoke contains toxic and harmful substances, which are directly discharged without effective purification treatment, posing a threat to the health of operators;

[0005] 3. Using push rods and pressure blocks as fixing devices, relying on threaded locking methods, the operation is cumbersome and time-consuming, affecting work efficiency. The threaded drive mechanism has efficiency bottlenecks during the tightening process, and it is easy to cause uneven tightening force, affecting the stability of deck fixation;

[0006] 4. The deck is moved to the welding table by a balance crane. After welding is completed, it needs to be detached by a balance crane again. The lifting is troublesome and not conducive to improving work efficiency. Summary of the invention

[0020] Compared with the prior art, the present invention provides a positioning device for deck welding, which has the following beneficial effects:

[0021] 1. The deck welding positioning device is provided with an electromagnet, a partition and a pressure groove. After the electromagnet is powered on, the deck is adsorbed through the protrusion. The state of the deck is controlled by controlling a pair of electromagnets on the support column to swing around the fixed column, so that the edge of the deck to be welded is roughly parallel to the partition, and the coarse adjustment is achieved. The suction force of the electromagnet at the bottom of the deck is reduced, and the deck is pushed so that the edge of the deck can maintain parallel contact with the partition, and the fine adjustment is achieved. After the adjustment, the suction force of the electromagnet is increased to limit the movement of the deck. During welding, when the first motor is working, the slider pushes the partition downward through the pressure groove, so that the partition moves to the bottom of the slide plate. The width of the partition is the gap that must be retained during welding, so that it is convenient to leave a precise welding gap between the two decks, thereby completing the rapid alignment adjustment and positioning of the deck.

[0022] 2. The deck welding positioning device is provided with a collecting frame and a sliding cylinder. During the welding process, as the sliding block approaches the welding position, the sliding cylinder is gradually pushed to move by the second spring. The sliding cylinder drives the collecting frame to slide at a certain distance from the welding point, and a negative pressure is formed at the collecting frame through the suction pipe, so that the smoke generated during welding can be removed to avoid inhalation by the workers and affect their health. After the welding is completed, the sliding block continues to push the sliding cylinder to move, the sliding cylinder flips, and the collecting frame is stored in the storage slot, so that the collecting frame can be hidden, thereby facilitating the operation of the welded deck.

[0023] 3. The deck welding positioning device is provided with a bracket and a rotating ball. After the deck is welded, the electromagnet above the second base stops working, and the electromagnet above the first base away from the collecting frame works and reduces its magnetic force, so that it is separated from the bottom end of the deck and supported by the rotating ball. The electromagnet still has an attraction with the deck. A conveyor belt is installed on the side of the bracket located at the collecting frame. The electromagnet rotates slowly around the fixed column. Since the electromagnet still has an attraction with the deck, the welded deck is pushed to move slowly onto the conveyor belt, which is convenient for welding the next deck and easy to operate.

[0048] Embodiment 3:

[0050] In the present invention, the exhaust component 53 includes a shell 531, the suction pipe 51 is equipped with the shell 531, the shell 531 is plugged with a collection box 532, the shell 531 is installed with an air pump 533, the suction pipe 51 is connected to the input end of the air pump 533, the output end of the air pump 533 is connected to the collection box 532, a penetrating filter cotton 534 is installed on one side of the collection box 532, and the collection box 532 is located at the filter cotton 534. A fan 535 is installed at the filter cotton 534, so as to form a negative pressure at the collection frame 521, so as to facilitate the suction of the smoke generated by welding and filter the harmful substances through the filter cotton 534.

[0051] In the present invention, the collecting frame 521 is connected to the collecting component 52, and the collecting component 52 includes an extension plate 523. The extension plates 523 are rotatably connected to both sides of the collecting frame 521. A torsion spring 524 is installed between the extension plate 523 and the collecting frame 521. Protective nets 522 are installed at the openings of the extension plate 523 and the collecting frame 521. A storage groove 54 for storing the collecting frame 521 is provided on the slide plate 31, thereby increasing the absorption angle and improving the removal efficiency of welding smoke.

[0052] When in use, two decks 4 are welded, and the two decks 4 are hoisted to the top of the bracket 1 by a balance crane, supported by the support rod 21, and the electromagnet 75 is started. After the electromagnet 75 is powered, the deck 4 is adsorbed by the protrusion 76, and the rotating ring 74 slides upward, and the third spring 79 is compressed. Each deck 4 is restricted in movement by a pair of electromagnets 75, so as to facilitate adjustment of welding. When the two decks 4 need to be aligned with each other, the third motor 732 is started, and the third motor 732 drives the second gear 733 to rotate through the first gear 731, thereby driving the rotating ring 74. The movable cylinder 78 and the support column 71 rotate, and the state of the deck 4 is controlled by controlling the pair of electromagnets 75 on the support column 71 to swing around the fixed column 25, so that the edge of the side of the deck 4 that needs to be welded is roughly parallel to the partition 36, and rough adjustment is achieved. The first electric push rod 32 is started to push the slide plate 31 and the partition 36 to the deck 4 on the side of the first base 23, so that the partition 36 and the deck 4 are easy to contact, and at the same time, the suction force of the electromagnet 75 at the bottom of the deck 4 is reduced, so that the deck 4 and the electromagnet 75 can be displaced, and the deck 4 is moved at the top of the support rod 21 through the contact of the partition 36. The ball 22 moves on the deck 4 so that the edge of the deck 4 can maintain parallel contact with the partition 36 to achieve fine adjustment. After the adjustment is completed, the suction force of the electromagnet 75 is increased to limit the movement of the deck 4, and the deck 4 above the second base 24 is adjusted. Similarly, after the coarse adjustment is performed through a pair of electromagnets 75 above the second base 24, the second electric push rod 62 is started to push the first guide wheel plate 61 to move. The first guide wheel plate 61 contacts the deck 4 above the second base 24, pushing it to contact the other side of the partition 36, so that it is aligned with the partition 36, and then it is adsorbed and fixed by the electromagnet 75 to limit the movement of the deck 4. The deck 4 moves, the second motor 722 works, and the second base 24 is driven to slide through the second screw rod 723, so as to adjust the position of the deck 4 above the second base 24, so that the ends of the two decks 4 are aligned, which is convenient for welding. During welding, when the first motor 38 works, the first screw rod 33 drives the slider 34 to slide, and the slider 34 pushes the partition 36 to move downward through the pressing groove 35, so that the partition 36 moves to the bottom of the slide plate 31, and the first spring 37 is stretched, and the width of the partition 36 is the gap that must be reserved during welding, so as to facilitate the accurate welding gap between the two decks 4;

[0053] During the welding process, as the slider 34 approaches the welding position, the second spring 58 gradually pushes the sliding cylinder 59 to move, and the sliding cylinder 59 drives the collecting frame 521 to slide at a certain distance from the welding point. The fan 535 works to form a negative pressure on one side of the filter cotton 534, and the suction pump 533 works to form a negative pressure at the collecting frame 521 through the suction pipe 51. The extension plate 523 is expanded by the torsion spring 524, thereby increasing the adsorption range. The protective net 522 isolates larger impurities, and the smoke generated by welding will be collected. The frame 521 is sucked in, and discharged into the collection box 532 through the suction pump 533, and is adsorbed and filtered by the filter cotton 534. After the welding is completed, the slider 34 continues to push the sliding cylinder 59 to move, and the sliding shaft 57 will slide to the end of the sliding groove 55, thereby pushing the sliding cylinder 59 to flip, and the collection frame 521 is collected into the storage groove 54. The rotating shell 56 rotates, the second spring 58 bends, the extension plate 523 rotates and contracts, and the torsion spring 524 is compressed, so that it is convenient to hide the collection frame 521, so as to facilitate the operation of the welded deck 4;

[0054] After the deck 4 is welded, the electromagnet 75 above the second base 24 is no longer working, and the electromagnet 75 above the first base 23 away from the collecting frame 521 is working, and its magnetic force is reduced, so that it is separated from the bottom end of the deck 4, and supported by rotating the ball 77. The electromagnet 75 still has an attraction with the deck 4, and the second electric push rod 62 is continuously started to move the first guide wheel plate 61 toward the second guide wheel plate 64, so as to clamp the welded deck 4, and a conveyor belt is installed on the side of the bracket 1 located at the collecting frame 521 to activate the third motor 732 on the first base 23, thereby driving the electromagnet 75 to rotate slowly around the fixed column 25. Since the electromagnet 75 still has an attraction with the deck 4, the welded deck 4 is pushed to move slowly onto the conveyor belt, which is convenient for welding the next deck 4 and easy to operate.

[0055] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
