Description

Technical Field

[0001] The present invention relates to the technical field of deburring, in particular to a mooring chain welding burr removal device. Background Art

[0002] Mooring chains, a crucial fixture in marine engineering, ships, and offshore platforms, require welding to connect the chain links during production. Welding often creates burrs at the weld joints. If these burrs are not promptly removed, they can affect the mooring chain's service life, mechanical performance, and safety. In severe cases, they can even lead to failures or accidents during offshore operations.

[0003] However, most deburring devices available on the market rely on manual operation or semi-automated equipment, using methods such as manual grinding and cutting to remove weld burrs. Manual deburring requires highly skilled workers, and due to the significant influence of human factors during operation, it is difficult to ensure that the burrs on each link are removed accurately and consistently. Prolonged manual operation can also cause worker fatigue, which in turn affects the safety and efficiency of the operation. Traditional deburring devices mostly rely on manual control or simple mechanical structures, making it difficult to accurately adjust the cutting position at various angles. As a result, the deburring effect is difficult to guarantee, especially in different parts of the chain link or on chain links with special angles, where incomplete deburring is prone to occur, affecting the quality of the final product.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further specifically described below through specific embodiments, but the present invention is not limited to these embodiments.

[0031] Combine Figures 1 to 10As shown, a mooring chain welding burr removal device includes a mooring chain hanger 1, on which a mooring chain is hung, a deburring workbench 2 is provided on one side of the mooring chain hanger 1, a circular through groove 21 is formed on the top of the deburring workbench 2, a ring-shaped moving device 3 is provided on the top of the deburring workbench 2, two anchor chain clamping mechanisms 4 and two bidirectional moving mechanisms 5 are provided on the top of the annular moving device 3, and a full-angle deburring device 6 is provided on the top of the bidirectional moving mechanism 5;

[0032] Combine Figure 10As shown, the full-angle deburring device 6 includes an L-shaped mounting plate 601, a first permanent magnet synchronous motor 602 is mounted on one side of the L-shaped mounting plate 601, an output end of the first permanent magnet synchronous motor 602 passes through the L-shaped mounting plate 601 and is connected to a rotating square plate 603, a rotating shaft 604 is fixedly connected to the center of the rotating square plate 603, and a semi-closed annular rack 605 is rotatably connected at both ends of the rotating shaft 604, and a semi-closed annular rack 605 is provided with a semi-closed annular groove 606 on the top and bottom of the semi-closed annular groove 606, a movable frame 607 is slidably connected in the semi-closed annular groove 606, a second permanent magnet synchronous motor 608 is mounted in the movable frame 607, and the second permanent magnet synchronous motor 608 outputs The end is connected to the first gear 609, and a driving motor 610 is installed on one side of the inner wall of the moving frame 607. The output end of the driving motor 610 passes through the moving frame 607 and is connected to the deburring head 611. A third permanent magnet synchronous motor 612 is installed on one side of the rotating square plate 603. The output end of the third permanent magnet synchronous motor 612 is connected to the driving gear 613. The surface of the rotating shaft 604 is fixedly connected to the driven gear 614. The rotating square plate 603 is driven to rotate by the first permanent magnet synchronous motor 602, and the rotating square plate 603 drives the semi-closed annular rack 605 to rotate, thereby driving the deburring head 611 of the moving frame 607 to rotate. The machine 612 drives the driving gear 613 to mesh with the driven gear 614. At this time, the driven gear 614 is fixedly connected to the rotating shaft 604. The two ends of the rotating shaft 604 are rotationally connected to the semi-closed annular rack 605, so the semi-closed annular rack 605 will rotate along the rotating shaft 604. At the same time, the deburring head 611 of the moving frame 607 will also rotate along the rotating shaft 604. The deburring head 611 can cut up and down the position to be deburred. The first gear 609 is driven by the second permanent magnet synchronous motor 608 to mesh with the semi-closed annular rack 605, so that the moving frame 607 will rotate along the semi-closed annular groove 606. When the deburring is being carried out After the surface position cutting is completed, the deburring head 611 is moved to the side position to be deburred by the bidirectional moving mechanism 5 and the second permanent magnet synchronous motor 608, and the side position to be deburred is cut. During this process, the deburring head 611 will perform multi-angle cutting. The deburring head 611 is driven by the driving motor 610 to cut. The two full-angle deburring devices 6 will simultaneously cut the front and back positions to be deburred, and then cut at the positions on both sides to be deburred. At this time, the welding burrs of the chain link are removed, and each part of the chain link can be accurately cut at multiple angles to ensure that the welding burrs in each part can be removed.

[0033] Combine Figure 10 As shown, the semi-enclosed annular rack 605 is meshed with the first gear 609, and the driving gear 613 is meshed with the driven gear 614, which can provide more stable transmission and avoid uneven deburring caused by uneven transmission.

[0034] Combine Figure 3 、 Figure 4 As shown, the annular moving device 3 includes an annular rack 301 and an annular track 302. The annular rack 301 and the annular track 302 are both mounted on the top of the deburring workbench 2. Four track trolleys 303 are mounted on the annular track 302. The tops of the four track trolleys 303 are all mounted with bottom plates 304. Two anchor chain clamping mechanisms 4 and two bidirectional moving mechanisms 5 are symmetrically mounted on the tops of the four bottom plates 304. A first servo motor 305 is mounted on the top of the bottom plates 304. The output end of the first servo motor 305 passes through the bottom plate 304 and is connected to a second gear 306. The second gear 306 is meshed with the annular rack 301. Next, the first servo motor 305 drives the second gear 306 to rotate, and the second gear 306 is meshed with the annular rack 301. The track trolley 303 moves on the annular track 302, and the annular rack 301 and the annular track 302 share the same geometric center. As a result, the four base plates 304 perform circular motion on the annular track 302, which can rotate the anchor chain clamping mechanism 4 and the two-way moving mechanism 5 to appropriate positions to clamp the chain links at different angles and remove welding burrs. This allows the device to adapt to different angles of the chain links, providing greater flexibility for clamping the chain links and removing welding burrs.

[0035] Combine Figure 5 As shown, the rail trolley 303 includes a support plate 3031, and four rollers 3032 are rotatably installed at the bottom of the support plate 3031. The four rollers slide on both sides of the circular track 302 respectively. The bottom plate 304 is connected to the support plate 3031, which can reduce the friction between the track and ensure the smooth operation of the device.

[0036] Combine Figure 6 As shown, the anchor chain clamping mechanism 4 includes a cylinder 401, which is horizontally installed on the top of the base plate 304. An arc-shaped clamp 402 is installed at the output end of the cylinder 401, so that the chain link can be accurately clamped, avoiding the displacement or loosening of the chain link during the deburring process, and improving the stability and accuracy of the deburring.

[0037] Combine Figure 7 、 Figure 8As shown, the bidirectional moving mechanism 5 includes two groups of bearing seats 501, the bearing seats 501 are installed on the top of the base plate 304, and a worm 502 is rotatably connected between each group of bearing seats 501. A second servo motor 503 is installed on the top of the base plate 304 on one side of each group of bearing seats 501. The two second servo motors 503 are respectively connected to the corresponding worm 502, and a worm gear 504 is meshed and connected between the two worm gears 502. The top of the worm gear 504 is connected to a third gear 505 through a connecting shaft. A first V-shaped guide column 506 is installed on the top of each group of bearing seats 501, and a sliding block 507 adapted thereto is slidably connected to the first V-shaped guide column 506. Two second V-shaped guide columns 508 are installed on the top of the two sliding blocks 507. The two second V-shaped guide columns 508 are installed on the top of the two sliding blocks 507. A rack frame 509 is slidably connected between the guide columns 508, and the two worms 502 are driven to rotate by the two second servo motors 503 respectively. The two worms 502 are simultaneously engaged with the worm gear 504. When the two worms 502 rotate in the same direction, the worm gear 504 will move along the worm 502. At this time, the rack frame 509 will move along the first V-shaped guide column 506. When the two worms 502 rotate in opposite directions, the worm gear 504 will rotate on its own. After the worm gear 504 rotates on its own, it drives the third gear 505 to rotate. The third gear 505 is engaged with the rack 5091 of the rack frame 509. At this time, the rack frame 509 will move along the direction of the second V-shaped guide column 508, so that the full-angle deburring device 6 can perform precise movement in the X and Y axis directions.

[0038] Combine Figure 9 As shown, the rack frame 509 includes two racks 5091, and connecting plates 5092 are installed on both sides of the two racks 5091. A V-shaped slider 5093 adapted to the second V-shaped guide column 508 is connected to one side of the rack 5091. A connecting vertical plate 5094 is connected to the top of the rack 5091. The two connecting vertical plates 5094 are jointly connected to the L-shaped mounting plate 601. The two racks 5091 are simultaneously engaged with the third gear 505. The third gear 505 is engaged with the rack 5091, and the rack frame 509 will move along the direction of the second V-shaped guide column 508, providing more stable guidance.

[0039] Combine Figure 3 As shown, the annular rack 301 and the annular track 302 share the same geometric center with the circular through slot 21 , so that the fit between the various components is tighter, reducing the instability and inaccuracy caused by errors.

[0040] Working Principle: During mooring chain production, one end of the mooring chain is first mounted on the mooring chain hanger 1 to ensure stable suspension for subsequent operations. After the chain links are fastened together, the joints are welded. After welding, weld burrs will appear on the chain links, requiring further removal. After welding, the mooring chain hanger 1 rotates its shaft rollers via a reduction motor, causing one end of the mooring chain to move upward, thereby moving the welded chain links into the appropriate position for the burr removal device. At this time, the two anchor chain clamping mechanisms 4 and the bidirectional moving mechanism 5 are moved to appropriate positions by the annular moving device 3, and the second gear 306 is driven to rotate by the first servo motor 305. The second gear 306 is meshed and connected with the annular rack 301. The track trolley 303 moves on the annular track 302, and the annular rack 301 and the annular track 302 share the same geometric center, so that the four base plates 304 make circular motion on the annular track 302. The anchor chain clamping mechanisms 4 on the top of the two opposite base plates 304 drive the arc-shaped clamps 402 to extend and retract through the cylinders 401. The two arc-shaped clamps 402 clamp the chain links after welding. The clamping position is below the burr. At this time, the chain links are fixed to prevent movement.The other two opposite bidirectional moving mechanisms 5 on the top of the bottom plates 304 respectively drive the two worms 502 to rotate through the two second servo motors 503. The two worms 502 are simultaneously engaged with the worm wheels 504. When the two worms 502 rotate in the same direction, the worm wheels 504 will move along the worms 502. At this time, the rack frame 509 will move along the first V-shaped guide column 506. When the two worms 502 rotate in opposite directions, the worm wheels 504 will rotate on their own. After the worm wheels 504 rotate on their own, they drive the third gear 505 to rotate. The third gear 505 is engaged with the rack 5091 of the rack frame 509. At this time, the rack frame 509 will move along the direction of the second V-shaped guide column 508, thereby making the gear 505 move in the direction of the second V-shaped guide column 508. The full-angle deburring device 6 is capable of moving in the X and Y axis directions, adjusting the position of the deburring head 611 so that the deburring head 611 contacts the position to be deburred, and the rotating square plate 603 is driven to rotate by the first permanent magnet synchronous motor 602, and the rotating square plate 603 drives the semi-closed annular rack 605 to rotate, thereby driving the deburring head 611 of the movable frame 607 to rotate, and the driving gear 613 is driven to engage with the driven gear 614 by the third permanent magnet synchronous motor 612. At this time, the driven gear 614 is fixedly connected to the rotating shaft 604, and both ends of the rotating shaft 604 are rotationally connected to the semi-closed annular rack 605, so the semi-closed annular rack 605 will rotate along the rotating shaft 604. The deburring head 611 of the movable frame 607 rotates, and the deburring head 611 of the movable frame 607 also rotates along the rotating shaft 604, and the deburring head 611 can cut up and down the position to be deburred, and the first gear 609 is driven by the second permanent magnet synchronous motor 608 to engage with the semi-closed annular rack 605, so that the movable frame 607 rotates along the semi-closed annular groove 606. When the front position to be deburred is cut, the deburring head 611 is moved to the side position to be deburred by the bidirectional moving mechanism 5 and the second permanent magnet synchronous motor 608 to cut the side position to be deburred. In this process, the deburring head 611 will perform multi-angle cutting, and the deburring head 611 is driven by the driving motor 610 to cut. 11 is cut, and the two full-angle deburring devices 6 will cut the front and back positions to be deburred at the same time, and then cut the positions on both sides to be deburred. At this time, the welding burrs of the chain link are removed. The mooring chain hanger 1 drives the shaft roller on it to rotate through the reduction motor, so that one end of the mooring chain moves upward, and a new chain link is buckled on one end of the mooring chain. The new chain link is basically at a ninety-degree angle with the previous chain link. At this time, the anchor chain clamping mechanism 4, the two-way moving mechanism 5 and the full-angle deburring device 6 are rotated to the appropriate position through the annular moving device 3, and then the chain link is clamped and the welding burr is removed. The process is repeated until the welding burrs of all chain links are removed.

[0041] The embodiments of the present invention are not limited to the above embodiments. Without departing from the spirit and scope of the present invention, ordinary technicians in this field can make various changes and improvements to the present invention in form and details, and these are all considered to fall within the scope of protection of the present invention.
