Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a steel plate welding device for shipbuilding. Background Technology

[0002] Steel plate welding equipment for shipbuilding is a key piece of equipment used to connect steel plates during shipbuilding and repair, as ships are usually welded together from a large number of steel plates.

[0003] Patent publication number CN117161598A discloses a steel plate welding device for ship processing, comprising a base plate and a welding robotic arm. The device is characterized by: clamping components one and two respectively arranged on the front and rear sides of the base plate; clamping components three arranged on the left and right sides of the base plate; and several support components arranged in the middle of the base plate for supporting the steel plate. Mounting plates are fixed on the left and right sides of the base plate, and a camera one is fixed on the side of the mounting plate closest to the base plate. The camera one is located between the weld seams of the spliced ​​steel plates and is used to capture the weld seam. A second camera is fixed on one side of the welding head of the welding robotic arm. The clamping component one includes a cylinder one and a bracket one. The bracket one is fixed on the base plate, and the cylinder one is fixed on the bracket one. Two sets of mounting plates are fixed in the middle of the bracket one. This device solves the current problem of poor welding accuracy.

[0004] However, the following problems still exist when the welding equipment for steel plates used in ship processing is in operation: Before welding the steel plates used in ship processing, two steel plates need to be joined together and clamped. During the clamping process, one side of the joint between the two steel plates may lift up, resulting in uneven welding between the two steel plates, which affects the quality and safety of the welding and is not conducive to the construction and maintenance of ships. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a steel plate welding device for shipbuilding, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel plate welding device for ship processing, comprising a base frame, a machine frame, and a welding device body. The machine frame is fixedly installed on the top of the base frame, and the welding device body is disposed on the top of the machine frame. A clamping device is provided on the top of the base frame. The clamping device includes a support plate, a rotating shaft, a threaded rod, a push plate, a clamping plate, a limiting block, a connecting block, an arc-shaped plate, a circular rod, and an insert plate. The support plate is rotatably connected to the top of the base frame. The rotating shaft penetrates the interior of the support plate. The threaded rod is threadedly connected to the right side of the support plate. The push plate and the clamping plate are slidably installed in the top groove of the support plate. The push plate is fixedly installed on the left side of the threaded rod, the limiting block is fixedly installed on the top of the push plate, the arc-shaped plate is rotatably installed on the top of the clamping plate, the connecting block is fixedly installed on the top of the arc-shaped plate, the circular rod is fixedly installed on the side of the arc-shaped plate away from the clamping plate, the insert plate is slidably installed on the bottom of the tray, the front of the frame is provided with a striking device, the bottom of the base frame is fixedly installed with a bottom box, and the bottom of the bottom box is provided with a collecting device. When installing the steel plate, the steel plate is placed inside the tray, the threaded rod is rotated to push the push plate to move towards the steel plate, the push plate moves when it moves, and the clamping plate clamps the steel plate when it moves.

[0007] According to the above technical solution, a spring is provided between the push plate and the clamping plate. Under the elastic action of the spring, the limiting block will contact the connecting block. The side of the insert plate that is inserted is set as an arc surface, which reduces the friction and facilitates the insertion of the insert plate into the bottom of the tray.

[0008] According to the above technical solution, the striking device includes an L-shaped rod, a connecting rod, a rotating rod, a rotating wheel, a rotating plate, a square rod, a hammer, and a rotating block. The L-shaped rod is fixedly installed on the top of the push plate, the connecting rod is fixedly installed on the left side of the L-shaped rod, the rotating rod is fixedly installed at the front of the frame, the rotating wheel is rotatably installed on the circumferential surface of the rotating rod, the rotating plate is rotatably installed at the front of the frame, the square rod is fixedly installed at the bottom of the rotating plate, the hammer is fixedly installed at the bottom of the square rod, and the rotating block is rotatably installed at the top of the connecting rod. When the clamp is released, the rotating threaded rod moves away from the steel plate. When the threaded rod moves, it drives the push plate to move. When the push plate moves, it drives the L-shaped rod to move. When the L-shaped rod moves, it drives the connecting rod to move.

[0009] According to the above technical solution, several protrusions are fixedly installed on the circumferential surface of the rotating wheel. The protrusions contact the rotating plate, causing the rotating plate to rotate intermittently, achieving the effect of the hammer intermittently striking the support plate. Several rectangular openings are provided at the bottom of the support plate, and the welding slag remaining in the support plate falls into the collection box at the bottom through the rectangular openings.

[0010] According to the above technical solution, the collection device includes a collection box, a T-shaped block, a guide plate, a support block, a pressure rod, a rotating frame, and a connecting plate. The collection box is fixedly installed at the bottom of the base box. The T-shaped block is fixedly installed at the bottom of the inner wall of the base box. The guide plate is fixedly installed on the left side of the T-shaped block. The support block is fixedly installed on the left side of the inner wall of the base box. The pressure rod is fixedly installed at the bottom of the support block. The rotating frame is rotatably installed on the right side of the inner wall of the base box. The top of the rotating frame is fixedly connected to the bottom of the pressure rod. The connecting plate is slidably installed on the bottom of the inner wall of the collection box. The connecting plate is fixedly installed on the left side of the rotating frame. When the rotating frame flips, it will drive the connecting plate to move to the left. When the connecting plate moves, it will drive the pressure plate to move. When the pressure plate moves, it will squeeze the welding slag in the collection box, increasing the amount of welding slag collected.

[0011] According to the above technical solution, the top of the T-shaped block is set as an inclined surface, and the bottom of the tray contacts the inclined surface. When the tray is flipped, the T-shaped block will limit the tray, so that the welding slag in the tray falls into the collection box. A first spring is provided between the support block and the pressure rod.

[0012] According to the above technical solution, the collection device further includes a pressure plate, a hydraulic cylinder one, a piston rod one, a hydraulic cylinder two, and a piston tube two. The pressure plate is slidably installed on the bottom of the inner wall of the collection box. The hydraulic cylinder one is fixedly installed on the left side of the connecting plate. The piston rod one slides through the interior of the hydraulic cylinder one and is fixedly connected to the pressure plate. The hydraulic cylinder two is fixedly installed on the bottom of the base frame. The piston tube two slides through the interior of the hydraulic cylinder two. The hydraulic cylinder one and the hydraulic cylinder two are connected by a hydraulic pipe.

[0013] According to the above technical solution, a second spring sheet is provided between the connecting plate and the pressure plate. Under the elastic action of the second spring sheet, the pressure plate will squeeze the connecting plate. The second piston tube contacts the support plate. When too much welding slag is collected, the second piston tube will limit the support plate so that the support plate will no longer flip.

[0014] This invention provides a steel plate welding device for shipbuilding. It has the following advantages:

[0015] (1) The invention uses clamps to hold steel plates to prevent gaps between the clamps from affecting the welding between the steel plates. During the clamping process, the connecting block is limited by the limiting block, so that the arc plate and the round rod are flipped, so that the round rod presses the top of the steel plate to prevent the connection of the steel plates from lifting up, which is beneficial to the welding between the steel plates and makes the welding of the steel plates more flat.

[0016] (2) In this invention, the rotating block on the connecting rod will limit the protrusion on the rotating wheel in one direction. When the clamp is released, the rotating wheel rotates and the protrusion on the rotating wheel will intermittently hit the rotating plate, so that the square rod and hammer connected to the bottom of the rotating plate will intermittently knock the steel plate inside the pallet, preventing the weld slag at the joint of the steel plate from accumulating too much. At the same time, the insert plate at the bottom of the pallet will disengage and the pallet will flip, so that the weld slag inside the pallet falls into the collection box at the bottom of the pallet, preventing the weld slag inside the pallet from accumulating too much and affecting the subsequent welding effect.

[0017] (3) In this invention, the pallet flips over to squeeze the lower pressure rod, which causes the connecting plate to drive the pressure plate to squeeze the welding slag in the collection box, thereby increasing the amount of welding slag collected. When there is too much welding slag in the collection box, the piston rod one squeezes to the right, causing the liquid in the hydraulic cylinder one to enter the hydraulic cylinder two. At this time, the piston rod two will limit the bottom of the pallet, so that the pallet will no longer flip over, preventing the welding slag in the collection box from accumulating too much and overflowing, thereby affecting the working environment.

[0027] 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.

[0028] Please see Figures 1-8 A steel plate welding device for ship processing includes a base frame 1, a machine frame 2, and a welding device body 3. The machine frame 2 is fixedly installed on the top of the base frame 1, and the welding device body 3 is located on the top of the machine frame 2. A clamping device is provided on the top of the base frame 1. The clamping device includes a support plate 401, a rotating shaft 402, a threaded rod 403, a push plate 404, a clamping plate 405, a limiting block 406, a connecting block 407, an arc-shaped plate 408, a circular rod 409, and an insert plate 410. The support plate 401 is rotatably connected to the top of the base frame 1. The rotating shaft 402 passes through the interior of the support plate 401. The threaded rod 403 is threadedly connected to the right side of the support plate 401. The push plate 404 and the clamping plate 405 are slidably installed in the top groove of the support plate 401. The limiting block 406 is fixedly installed on the top of the push plate 404, the arc plate 408 is rotatably installed on the top of the clamping plate 405, the connecting block 407 is fixedly installed on the top of the arc plate 408, the circular rod 409 is fixedly installed on the side of the arc plate 408 away from the clamping plate 405, the insert plate 410 is slidably installed on the bottom of the support plate 401, the front of the frame 2 is provided with a striking device, the bottom of the base frame 1 is fixedly installed with a bottom box 7, and the bottom of the bottom box 7 is provided with a collecting device. The connecting block 407 is limited by the limiting block 406, so that the arc plate 408 and the circular rod 409 are flipped, so that the circular rod 409 presses the top of the steel plate to prevent the joint of the steel plate from lifting.

[0029] A spring is provided between the push plate 404 and the clamping plate 405. Under the elastic action of the spring, the limiting block 406 will contact the connecting block 407. The side of the insert plate 410 that is inserted is set as an arc surface, which reduces the friction and facilitates the insertion of the insert plate 410 into the bottom of the support plate 401.

[0030] The striking device includes an L-shaped rod 501, a connecting rod 502, a rotating rod 503, a rotating wheel 504, a rotating plate 505, a square rod 506, a hammer 507, and a rotating block 508. The L-shaped rod 501 is fixedly installed on the top of the push plate 404, the connecting rod 502 is fixedly installed on the left side of the L-shaped rod 501, the rotating rod 503 is fixedly installed at the front of the frame 2, the rotating wheel 504 is rotatably installed on the circumferential surface of the rotating rod 503, the rotating plate 505 is rotatably installed at the front of the frame 2, the square rod 506 is fixedly installed at the bottom of the rotating plate 505, the hammer 507 is fixedly installed at the bottom of the square rod 506, and the rotating block 508 is rotatably installed on the top of the connecting rod 502. When the rotating wheel 504 rotates, the protrusions on the rotating wheel 504 intermittently strike the rotating plate 505, causing the square rod 506 and the hammer 507 connected to the bottom of the rotating plate 505 to intermittently strike the steel plate inside the support plate 401, preventing excessive accumulation of weld slag at the joint of the steel plate.

[0031] Several protrusions are fixedly installed on the circumferential surface of the rotating wheel 504. The protrusions contact the rotating plate 505, causing the rotating plate 505 to rotate intermittently, achieving the effect of the hammer 507 intermittently striking the support plate. Several rectangular openings are provided at the bottom of the support plate 401, and the welding slag remaining in the support plate 401 falls into the collection box 601 at the bottom through the rectangular openings.

[0032] The collection device includes a collection box 601, a T-shaped block 602, a guide plate 603, a support block 604, a pressure rod 605, a rotating frame 606, and a connecting plate 607. The collection box 601 is fixedly installed at the bottom of the base box 7. The T-shaped block 602 is fixedly installed at the bottom of the inner wall of the base box 7. The guide plate 603 is fixedly installed on the left side of the T-shaped block 602. The support block 604 is fixedly installed on the left side of the inner wall of the base box 7. The pressure rod 605 is fixedly installed at the bottom of the support block 604. The rotating frame 606 is rotatably installed on the right side of the inner wall of the base box 7. The top of the rotating frame 606 is fixedly connected to the bottom of the pressure rod 605. The connecting plate 607 is slidably installed at the bottom of the inner wall of the collection box 601. The connecting plate 607 is fixedly installed on the left side of the rotating frame 606. The support plate 401 flips to press the pressure rod 605, causing the connecting plate 607 to drive the pressure plate 608 to press the welding slag in the collection box 601, thereby increasing the amount of welding slag collected.

[0033] The top of the T-shaped block 602 is set as an inclined surface, and the bottom of the tray 401 contacts the inclined surface. When the tray 401 is flipped, the T-shaped block 602 will limit the tray 401, so that the welding slag in the tray 401 falls into the collection box 601. A first spring is provided between the support block 604 and the pressure rod 605.

[0034] The collection device also includes a pressure plate 608, a hydraulic cylinder 609, a piston rod 610, a hydraulic cylinder 611, and a piston tube 612. The pressure plate 608 is slidably installed on the bottom of the inner wall of the collection box 601. The hydraulic cylinder 609 is fixedly installed on the left side of the connecting plate 607. The piston rod 610 slides through the interior of the hydraulic cylinder 609 and is fixedly connected to the pressure plate 608. The hydraulic cylinder 611 is fixedly installed on the bottom of the base frame 1. The piston tube 612 slides through the interior of the hydraulic cylinder 611. The hydraulic cylinders 609 and 611 are connected by a hydraulic pipe.

[0035] A second spring sheet is provided between the connecting plate 607 and the pressure plate 608. Under the elastic action of the second spring sheet, the pressure plate 608 will squeeze the connecting plate 607. The piston tube 612 contacts the support plate 401. When too much welding slag is collected, the piston tube 612 will limit the support plate 401, so that the support plate 401 will no longer flip.

[0036] During operation: When installing the steel plate, place the steel plate inside the support plate 401, rotate the threaded rod 403 to push the push plate 404 towards the steel plate. When the push plate 404 moves, it will drive the clamping plate 405 to move. When the clamping plate 405 moves, it will clamp the steel plate. Under the reverse force, the clamping plate 405 moves away from the steel plate. When the clamping plate 405 moves, it will drive the connecting block 407 to move. When the connecting block 407 moves, it will contact the limiting block 406. The limiting block 406 will limit the connecting block 407, causing the arc plate 408 to flip. When the arc plate 408 flips, it will drive the circular rod 409 to flip. When the circular rod 409 flips, it will press down on the steel plate to prevent the steel plate from tilting and affecting the welding.

[0037] When the clamp is released, the threaded rod 403 is rotated and moved away from the steel plate. This movement of the threaded rod 403 causes the push plate 404 to move, which in turn causes the L-shaped rod to move. The L-shaped rod then moves the connecting rod 502, which in turn moves the rotating block 508. As the rotating block 508 moves, it contacts the protrusion on the rotating wheel 504, causing the wheel 504 to rotate. The rotating wheel 504 is rotatably connected to the circumferential surface of the rotating rod 503. When the wheel 504 rotates, the protrusion will... The rotating plate 505 is pressed down, causing it to rotate. When the rotating plate 505 rotates, it drives the square rod 506 to move downward. When the square rod 506 moves, it drives the hammer 507 to move. When the hammer 507 moves, it intermittently strikes the steel plate, causing the weld slag at the joint of the steel plate to vibrate and fall off. When the threaded rod 403 moves to a certain position, it releases the limit on the insert plate 410. At this time, the support plate 401 will flip over. When the support plate 401 flips over, the weld slag inside will fall into the collection box 601 at the bottom, which is beneficial for the collection of weld slag.

[0038] When the pallet 401 flips, the pressure rod 605 moves downward. The movement of the pressure rod 605 causes the rotating frame 606 to flip, which in turn causes the connecting plate 607 to move to the left. The movement of the connecting plate 607 then causes the pressure plate 608 to move. The pressure plate 608, when moving, compresses the welding slag in the collection box 601, increasing the amount of welding slag collected. When too much welding slag is collected, the pressure plate 608 moves to the right, compressing the piston rod 610. This causes the liquid in the hydraulic cylinder 609 to enter the hydraulic cylinder 611 through the hydraulic pipe. The liquid entering the hydraulic cylinder 611 compresses the piston tube 612, causing it to move to the right. The movement of the piston tube 612 limits the pallet 401, preventing it from flipping and avoiding excessive welding slag accumulation in the collection box 601, which could then overflow and affect the working environment.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
