Description

Technical Field

[0001] This invention belongs to the technical field of ship processing equipment, and specifically relates to a welding device for ship manufacturing. Background Technology

[0002] A ship is a man-made means of transportation that primarily operates in water. Civilian ships are generally called boats, military ships are called warships, and small boats are called vessels or dinghies; collectively, they are referred to as ships or dinghies. Internally, they mainly include interior space, supporting structures, and drainage structures, and have a propulsion system that utilizes external or internal energy sources. Their shape is generally a streamlined envelope that helps overcome fluid resistance. Materials are constantly being updated with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials primarily include steel, aluminum, fiberglass, acrylic, and various composite materials. In shipbuilding, laser cutting equipment is typically used to cut the sheet metal, and laser welding equipment is also needed to weld the sheet metal.

[0003] Most existing welding equipment used in shipbuilding involves placing plates on a workbench and welding them manually using the equipment. This method has a low degree of automation, and manual welding can cause burns to workers, posing certain safety hazards. Summary of the Invention

[0004] This invention provides a welding device for shipbuilding, which aims to solve the problems of existing welding devices for shipbuilding, which mostly involve placing plates on a workbench and welding manually using welding equipment, resulting in low automation. In addition, manual welding may cause burns to personnel during use, posing certain safety hazards.

[0005] This invention provides a welding device for shipbuilding, comprising a lower support, an upper support mounted on the lower support, a movable module mounted on the upper support, a fastening module mounted on the movable module, welding modules mounted on both sides of the upper end of the lower support, and two sets of adjustment modules mounted on the left and right sides of the welding modules. The fastening module includes an assembly plate. An air pump is fixed to the bottom of the assembly plate. Two pairs of support columns are fixed to the lower end of the assembly plate. A sealing cover is fixed to the lower end of the support columns. An assembly piece is fixed to the lower end of the sealing cover. Channel A is fixed to the side of the sealing cover furthest from the assembly piece. Channel A is connected to the air pump. Several assembly slots are reserved on the assembly piece. An anti-detachment unit is fixed to each assembly slot. A sealing unit is fixed to the side of the anti-detachment unit furthest from the assembly piece to control the connection between the anti-detachment unit and the sealing cover. The anti-detachment unit includes a channel B fixed in the assembly slot, a movable silicone tube clamped to the channel B, a constraint platform mirrored and fixed to the wall surface of the silicone tube farther from the channel B, a movable piece fixed to the side of the channel B inside the silicone tube, and a clamping cylinder fixed to the side of the channel B extending into the sealing cover. The sealed unit includes a connecting strip that is uniformly fixed to the inner surface of channel B. The side of the connecting strip that is farthest from the inner surface of channel B is fixed to a variable cylinder. A variable column is movably installed in the variable cylinder. The variable column passes through the variable cylinder. The side of the variable column that is close to the traction strip is fixed to a bonding platform. An insertion interface is reserved on the outer surface of the bonding platform that is close to the bead B. The side of the variable column that is farthest from the bonding platform is fixed to bead A. Bead A is in the hoop. The connecting unit for assembling the bonding platform is fixed to the inner surface of the silicone tube that is close to the bonding platform. The connecting unit includes a traction bar fixed to the inner surface of the silicone tube near the constraint platform. The side of the traction bar furthest from the silicone tube is screwed to the bead B. A square bar is fixed to the moving piece near the bead B. A constraint bar is movably installed on the side of the square bar furthest from the moving piece. The constraint bar passes through the square bar. The side of the constraint bar furthest from the bead B is fixed to the pressure platform. A spiral beryllium copper wire is clamped onto the constraint bar. One side of the spiral beryllium copper wire is fixed to the pressure platform, and the other side of the spiral beryllium copper wire is fixed to the square bar.

[0006] Furthermore, several rollers are screwed onto the tabletop of the lower support.

[0007] Furthermore, the moving module includes a track fixed to the upper support, a bidirectional lead screw screwed into the track, sliders screwed to both sides of the bidirectional lead screw, a motor fixed to one side of the track, the output end of the motor fixed to the bidirectional lead screw, and an electric telescopic rod fixed to the lower end of the slider.

[0008] Furthermore, one side of the constraint bar extends into the interface.

[0009] Furthermore, the side of the pressure table furthest from the variable plate is arched.

[0010] Furthermore, the traction bar is set at an angle, and the distance between the traction bar and the variable plate decreases from one side near the silicone tube to the other side.

[0011] Furthermore, when bead A is sealed to the hoop, the mating platform is inside the silicone tube, and the side of the hoop farther from channel B is funnel-shaped.

[0012] Furthermore, the diameter of channel B is larger than the diameter of the variable cylinder.

[0013] Furthermore, the welding module includes a robotic arm fixed to the lower support, with a welding head mounted at the head end of the robotic arm.

[0014] Furthermore, the adjustment module includes a fixed base fixed to the lower bracket, an electric telescopic rod II fixed to the fixed base, and a push plate fixed to the output end of the electric telescopic rod II.

[0015] The beneficial effects of this invention are as follows: 1. In the welding process of this invention, the plate is placed on the lower support, the adjustment module adjusts the plate so that the welding positions of the plate are aligned with each other, the moving module drives the fastening module to move down, the fastening module fastens the plate, and then the moving module moves the welding positions of the two plates to fit together, and the welding module performs welding on the plate, realizing automatic and precise welding of the plate, ensuring the accuracy and safety of the welding.

[0016] 2. Through the installation of the sealing unit and the anti-detachment unit, when the sealing unit is attached to the outer wall of the board, the corresponding anti-detachment unit is connected to the sealing cover, and then the anti-detachment unit is tightly attached to the board. This prevents the anti-detachment unit from being connected when there are textures on the board, which would weaken the fastening effect of the device on the board. This also prevents the board from loosening or even falling off during the fastening process. By installing the silicone sleeve and channel B, when fastening a heavier plate, the silicone sleeve moves on channel B and pulls the sealing unit to perform sealing, making the cavity in the silicone sleeve larger, enhancing the silicone sleeve's fastening effect on the plate, and further preventing the plate from falling off.

[0017] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-7 This invention provides a welding device for shipbuilding, comprising a lower support 1, an upper support 2 mounted on the lower support 1, a movable module 3 mounted on the upper support 2, a fastening module 4 mounted on the movable module 3, welding modules 5 mounted on both sides of the upper end of the lower support 1, and two sets of adjustment modules 6 mounted on the left and right sides of the welding modules 5.

[0021] During welding, the plates are placed on the lower support 1, and the adjustment module 6 adjusts the plates so that the welding positions of the plates are aligned. The moving module 3 drives the fastening module 4 to move down, and the fastening module 4 fastens the plates. Then, the moving module 3 moves the welding positions of the two plates to fit together, and the welding module 5 performs welding on the plates, realizing automatic and precise welding of the plates and ensuring the accuracy and safety of the welding.

[0022] Reference Figure 1 Several rollers 11 are screwed onto the table of the lower support 1. The surface of the rollers 11 extends out of the table of the lower support 1. The installation of the rollers 11 facilitates the movement of the board.

[0023] Reference Figure 1 and Figure 2 The moving module 3 includes a track 31 fixed to the upper support 2. A bidirectional lead screw 32 is screwed into the track 31. Slider 33 is screwed to both sides of the bidirectional lead screw 32. A motor 34 is fixed to one side of the track 31. The output end of the motor 34 is fixed to the bidirectional lead screw 32. The lower end of the slider 33 is fixed to an electric telescopic rod 35. When it is necessary to fasten the plate, the electric telescopic rod 35 extends, allowing the fastening module 4 to move down. The fastening module 4 fastens the plate. After the fastening is completed, the motor 34 drives the bidirectional lead screw 32 to rotate. The bidirectional lead screw 32 drives the slider 33 to move. The slider 33 pulls the fastened plate below the electric telescopic rod 35 to move until the weld joint of the two plates is moved to touch, realizing the smooth movement of the fastened plate and facilitating automatic welding.

[0024] Reference Figures 3-7 The fastening module 4 includes an assembly plate 426 fixed to the output end of the electric telescopic rod 35. An air pump 425 is fixed to the bottom of the assembly plate 426. Two pairs of support columns 427 are fixed to the lower end of the assembly plate 426. A sealing cover 42 is fixed to the lower end of the support column 427. An assembly piece 41 is fixed to the lower end of the sealing cover 42. A channel A43 is fixed to the side of the sealing cover 42 that is farther from the assembly piece 41. The channel A43 is connected to the air pump 425. Several assembly slots 44 are reserved on the assembly piece 41. An anti-detachment unit 45 is fixed to each assembly slot 44. A sealing unit 46, which is used to control the connection between the anti-detachment unit 45 and the sealing cover 42, is fixed to the side of the anti-detachment unit 45 that is farther from the assembly piece 41.

[0025] In the initial state, the sealing unit 46 seals the anti-detachment unit 45 and the sealing cover 42 together. When fastening the plate, the anti-detachment unit 45 is transferred to the plate. When the sealing unit 46 touches the outer wall of the plate, the sealing unit 46 releases the seal between the sealing cover 42 and the anti-detachment unit 45, allowing the sealing cover 42 and the anti-detachment unit 45 to connect with each other. Then, the air pump 425 performs air suction in the sealing cover 42, thereby reducing the air pressure in the sealing cover 42 and the connected anti-detachment unit 45, which in turn can tighten the plate, ensuring a stable fastening of the plate. This prevents unevenness of the plate surface from affecting the fastening of the plate, avoids all anti-detachment units 45 being in a connected state, which would weaken the fastening effect on the plate, and ensures a stable fastening of the plate.

[0026] Reference Figure 5 The anti-detachment unit 45 includes a channel B47 fixed in the assembly groove 44. A movable silicone cylinder 48 is clamped to the channel B47. A constraint table 49 is mirror-fixed to the wall surface of the silicone cylinder 48 that is farther away from the channel B47. A movable piece 410 is fixed to one side of the channel B47 in the silicone cylinder 48. A clamp 411 is fixed to one side of the channel B47 that extends into the sealing cover 42.

[0027] In the initial state, due to the weight of the silicone sleeve 48, the top of the silicone sleeve 48 and the top of the movable piece 410 are in contact with each other. When fastening the plate, the silicone sleeve 48 moves to be in contact with the wall of the plate. The silicone sleeve 48 moves on the channel B47, causing the movable piece 410 to move to be in contact with the constraint table 49. This reduces the size of the cavity connecting the silicone sleeve 48 and the sealing cover 42. When the air pump 425 works, the air pressure in the silicone sleeve 48 can decrease rapidly, thereby quickly reinforcing the plate and ensuring the stability of the plate fastening.

[0028] Reference Figure 6 and Figure 7 The sealed unit 46 includes a connecting strip 412 uniformly fixed to the inner surface of the channel B47. The side of the connecting strip 412 furthest from the inner surface of the channel B47 is fixed to a variable cylinder 413. A variable column 414 is movably installed in the variable cylinder 413. The variable column 414 passes through the variable cylinder 413. The side of the variable column 414 near the traction strip 419 is fixed to a bonding platform 415. An insertion interface 416 is reserved on the outer surface of the bonding platform 415 near the bead B420. The side of the variable column 414 furthest from the bonding platform 415 is fixed to a bead A417. The bead A417 is located in the clamp 411. The connecting unit 418 for assembling the bonding platform 415 is fixed to the inner surface of the silicone tube 48 near the bonding platform 415.

[0029] Reference Figure 7 The connecting unit 418 includes a traction bar 419 fixed to the inner surface of the silicone cylinder 48 near the constraint table 49. The side of the traction bar 419 furthest from the silicone cylinder 48 is screwed to the bead B420. A square bar 421 is fixed to the moving piece 410 near the bead B420. A constraint bar 422 is movably installed on the side of the square bar 421 furthest from the moving piece 410. The constraint bar 422 passes through the square bar 421. The side of the constraint bar 422 near the bead B420 is fixed to the pressure table 423. A spiral beryllium copper wire 424 is clamped onto the constraint bar 422. One side of the spiral beryllium copper wire 424 is fixed to the pressure table 423, and the other side of the spiral beryllium copper wire 424 is fixed to the square bar 421.

[0030] In the initial state, under its own weight, bead A417 seals the space between the clamp 411 and the sealing cover 42. When the plate becomes heavier, as the silicone cylinder 48 moves to the plate and adheres to the plate wall, the bonding platform 415 adheres to the plate wall and moves. The movement of the bonding platform 415 pulls the movement column 414, which in turn pulls the bead A417, causing the bead A417 to release the seal between the clamp 411 and the sealing cover 42, allowing the clamp 411 and the sealing cover 42 to connect. The air pressure in the silicone cylinder 48 decreases, tightening the plate. As the silicone cylinder 48 moves, it pulls the traction bar 419, which in turn pulls the bead B420. The bead B420 and the pressure table 423 adhere tightly to each other, and the pressure table 423 inhibits the deformation of the spiral beryllium copper wire 424. The action moves towards the bonding platform 415, and the pressure platform 423 moves to pull the constraint bar 422 to move, so that the other side of the constraint bar 422 moves into the insertion interface 416, thereby maintaining the connection between the sealing cover 42 and the silicone tube 48, and performing fastening on the plate. When fastening a heavier plate, the silicone tube 48 moves downward under the pull of the plate's weight, and the movement of the silicone tube 48 pulls the pressure platform 423 downward, thereby separating the bead B420 and the pressure platform 423 from each other. With the cooperation of the spiral beryllium copper wire 424, the constraint bar 422 and the insertion interface 416 separate from each other, allowing the bead A417 to seal the space between the sealing cover 42 and the silicone tube 48 under its own weight. When the silicone tube 48 falls, the cavity between the silicone tube 48 and the moving piece 410 increases, thereby reducing the air pressure in the silicone tube 48, enhancing the suction effect of the silicone tube 48 on the plate, and preventing the plate from falling off.

[0031] Reference Figure 7 The constraint bar 422 extends into the insertion interface 416, thereby constraining the mating platform 415.

[0032] Reference Figure 7 The side of the pressure table 423 that is farther from the variable plate 410 is arched, so that the traction bar 419 can easily pull the pressure table 423 to perform the change via the bead B420.

[0033] Reference Figure 6 The traction bar 419 is set at an angle, and the distance between the traction bar 419 and the changing plate 410 gradually shortens from one side near the silicone cylinder 48 to the other side, so that the traction bar 419 can be moved by the ball body B420 to the pressure table 423.

[0034] Reference Figure 5 When the bead A417 is sealed to the clamp 411, the bonding table 415 is in the silicone tube 48. When the bonding table 415 and the plate are bonded, the cavity between the silicone tube 48 and the plate is very small, which can quickly form a strong air pressure to firmly suction the plate.

[0035] Reference Figure 7 The diameter of channel B47 is larger than that of the variable cylinder 413. A cavity is reserved between the variable cylinder 413 and channel B47 so that the gas in the silicone cylinder 48 can be discharged through this cavity. The reduced gas pressure in the silicone cylinder 48 tightens the plate.

[0036] Reference Figure 6 The side of the hoop 411 that is farther from the channel B47 is funnel-shaped, which can quickly connect the sealing cover 42 and the silicone tube 48 when the bead A417 moves.

[0037] Reference Figure 1 The welding module 5 includes a robotic arm 51 fixed to the lower support 1. A welding head 52 is installed at the head end of the robotic arm 51. The robotic arm 51 adjusts the position of the welding head 52 so that the welding head 52 performs welding on the welding point of the plate, thereby realizing automatic welding of the plate.

[0038] Reference Figure 1 The adjustment module 6 includes a fixed base 61 fixed to the lower support 1. An electric telescopic rod 62 is fixed to the fixed base 61. The output end of the electric telescopic rod 62 is fixed to a push plate 63. Before fastening the plate, the plate is placed on the roller 11. The electric telescopic rod 62 extends and pushes the push plate 63 to move, so that the push plate 63 moves to both sides of the plate, thereby aligning the plate so that the welding points of the plate are aligned with each other, realizing automatic adjustment of the plate and ensuring that the plate can be welded normally.
