Description

Technical Field

[0001] This invention relates to the field of welding positioning technology, and more specifically, to a welding component positioning device for welding equipment used on the outer wall of large ships. Background Technology

[0002] In the construction of large ships, the welding of the hull outer wall is one of the core processes. The positioning accuracy of the welded parts directly determines the structural strength, sealing performance, and appearance quality of the hull. The hull outer wall of large ships is enormous in size and complex in surface curvature, and the welded parts are made of various materials (including steel and composite materials). Frequent adjustments to the positioning position, angle, and adsorption method are required, which places extremely high demands on the flexibility, adaptability, and stability of the positioning device.

[0003] For example, Chinese patent application CN109604910A discloses an intelligent welding positioning device for ship plates, which includes a base, a fixed seat, a cavity, a through groove, and a first telescopic rod. The device has a fixed ring set on a movable plate, a screw with a rotating disk set inside the fixed ring, and a third fixed disk with a push plate set on the rotating disk, so as to fix the plate to the hull. This makes it easier for workers to weld the plate to the hull, saving time and effort, and avoiding dangers during the welding process.

[0004] For example, Chinese Patent CN119457679B discloses a welding guidance and alignment device and method for ship hull structure manufacturing, which includes two housings, a drive motor, an air pump, a cable winding mechanism, and an installation mechanism. When the angle between two ship plates is large, the device can rotate the extrusion tube on the outer surface of the second round rod, and under the action of cable winding, drive the installation ring to move towards the angle between the ship plates, thereby precisely adjusting the angle of the ship plates and ensuring they are in the correct mating position. Applying appropriate pressure to the ship plates through the extrusion tube can reduce the welding gap and avoid the occurrence of incomplete welds. At the same time, good angle alignment helps to evenly distribute welding stress and prevent excessive local stress.

[0005] However, the above-mentioned devices still have some shortcomings: the existing technology requires manual assistance to move the welded parts to the positioning device, and it cannot make the welded parts fit precisely against the hull wall. At the same time, the single adsorption structure is not suitable for welded parts of different materials, making it inconvenient to position welded parts of different materials.

[0006] Therefore, we have made improvements and proposed a welding component positioning device for welding equipment on the outer wall of large ships in order to solve the problems mentioned above. Summary of the Invention

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-8This invention proposes a welding component positioning device for welding equipment on the outer wall of large ships, comprising two parallel columns 1, a moving and shifting mechanism 2 on the bottom wall of the two columns 1, a mounting plate 3 fixed between the top ends of the two columns 1, a connecting plate 4 rotatably connected to the bottom front end of the mounting plate 3, three top plates 5 evenly arranged below the connecting plate 4, a lifting component 6 on the connecting plate 4, and an adjusting component 7 on the top plates 5, each of the three top plates 5 being fixed to an assembly plate 9 by a fixing column 8, an assembly frame 10 fixed at the center of the upper end face of the assembly plate 9, rotating rods 11 rotatably connected to the left and right side walls of the assembly frame 10, a switching plate 12 fixed to the outer end of each rotating rod 11, and sliding openings 13 at both ends of the switching plate 12, within which sliding openings 13 are provided. A sliding column 14 is connected, and a lifting column 15 is fixed to the rear end of the sliding column 14. A guide sleeve 16 is slidably connected to the lifting column 15, and the guide sleeve 16 is fixedly connected to the assembly plate 9. The bottom of the lifting column 15 passes through the assembly plate 9 and extends to the lower part. Vacuum suction cups 17 are installed at the bottom of the two diagonally opposite lifting columns 15 respectively. Electromagnets 18 are installed at the bottom of the other two diagonally opposite lifting columns 15. The inner end of the rotating rod 11 is fixed with a first bevel gear 19. A rotating shaft 20 is rotatably connected to the center of the upper end face of the assembly frame 10. The bottom end of the rotating shaft 20 is fixed with a second bevel gear 21 that meshes with the two first bevel gears 19 respectively. The top end of the rotating shaft 20 is fixed with a third bevel gear 22. A linkage component 23 is provided on the top plate 5, and a flipping component 24 is provided on the connecting plate 4.

[0023] The overall horizontal movement and angle adjustment are achieved through the movable positioning mechanism 2, providing a flexible working position for welding the outer wall of large ships. The mounting plate 3 serves as the supporting foundation for the superstructure. The flipping component 24 drives the connecting plate 4 and the welding components below it to flip, adapting to welding requirements at different angles. It also facilitates the fixing and loading of welded parts without manual handling and fixing. The three top plates 5 provide a stable support platform, and the adjustment component 7 on them is used to precisely adjust the position of the assembly plate 9 to ensure accurate positioning of the welded parts. When the rotating rod 11 rotates, the switching plate 12 drives the sliding column 14 through the sliding port 13, which in turn drives the lifting column 15 to move up and down along the guide sleeve 16. Since the two switching plates 12 are tilted in opposite directions, the rotating rod... When the rotating rod 11 rotates, the two diagonally opposite lifting columns 15 will descend synchronously, and the other two diagonally opposite lifting columns 15 will rise synchronously, realizing the switching between the vacuum suction cup 17 and the electromagnet 18. When the vacuum suction cup 17 descends, it can adsorb non-metallic or welded parts that need to avoid magnetic influence. When the electromagnet 18 descends, it can adsorb magnetic welded parts such as steel, meeting the positioning requirements of welded parts of different materials. The first bevel gear 19 at the inner end of the rotating rod 11 meshes with the second bevel gear 21 at the bottom end of the rotating shaft 20. The third bevel gear 22 at the top end of the rotating shaft 20 provides an interface for linkage transmission, ensuring that the two rotating rods 11 on the same assembly frame 10 rotate synchronously in opposite directions. The linkage component 23 realizes the synchronous linkage adjustment of the three assembly plates 9, ensuring the coordination and consistency of the welding operation.

[0024] like Figure 1 , Figure 2 and Figure 8 As shown, the movable switching mechanism 2 includes a movable plate 201 disposed on the lower side of two columns 1. A turntable 202 is disposed at the center of the movable plate 201. The upper end of the turntable 202 is fixedly connected to the bottom end of the two columns 1. A first motor 203 is fixedly connected to the lower end of the movable plate 201. The driving end of the first motor 203 passes through the movable plate 201 and is fixedly connected to the turntable 202. An arc-shaped opening 204 is provided on the turntable 202. A limiting post 205 is provided in one end of the arc-shaped opening 204. The bottom end of the limiting post 205 is fixedly connected to the upper end of the movable plate 201.

[0025] The first motor 203 drives the turntable 202 to rotate, which in turn drives the column 1 to rotate, thereby enabling the device to adjust its angle in the horizontal plane; the limiting column 205 moves within the arc-shaped opening 204 to limit the rotation angle of the turntable 202.

[0026] like Figure 1 , Figure 2 and Figure 8 As shown, wheel frames 206 are fixedly connected to the four corners of the lower end face of the movable plate 201. Rollers 207 are rotatably connected inside the wheel frames 206. A second motor 208 is fixedly connected to the outer wall of the wheel frames 206. The driving end of the second motor 208 is fixedly connected to the shaft end of the roller 207. Guide rails 209 are provided on the lower side of the adjacent rollers 207 laterally.

[0027] The second motor 208 drives the roller 207 to roll on the guide rail 209, realizing the linear movement of the device in the horizontal direction. Multiple guide rails 209 can be set up and spliced ​​together. At the same time, the guide rails 209 can also be deployed on the lifting platform for use.

[0028] like Figure 1 and Figure 4 As shown, the lifting assembly 6 includes two first telescopic cylinders 601 that are symmetrically fixed at both ends of the upper surface of the connecting plate 4. The driving ends of the two first telescopic cylinders 601 pass through the connecting plate 4 and are fixedly connected to a support plate 602. The support plate 602 is fixedly connected to the top plate 5 at the center.

[0029] The first telescopic cylinder 601 extends and retracts, driving the support plate 602 to move up and down, thereby driving the top plate 5 at the center to rise and fall, realizing the lifting and lowering operation of the components related to the top plate 5.

[0030] like Figure 1 , Figure 5 and Figure 6As shown, the positioning assembly 7 includes a servo motor 701 fixed at the center of the lower end face of the central top plate 5. The drive end of the servo motor 701 passes through the top plate 5 and is fixedly connected to a transmission gear 702. The upper end face of the central top plate 5 is symmetrically connected to two sets of guide blocks 703. A toothed column 704 that meshes with the transmission gear 702 is slidably connected between two adjacent guide blocks 703. A fixing seat 705 is fixedly connected to the outer end of the toothed column 704. The lower end face of the fixing seat 705 is fixedly connected to the upper end face of the outer top plate 5. A limiting piece 706 is fixedly connected to the end of the toothed column 704 away from the fixing seat 705.

[0031] When the servo motor 701 drives the transmission gear 702 to rotate, it will cause the two toothed columns 704 to slide synchronously in opposite directions along the guide block 703. In turn, the fixed seat 705 will drive the two outer top plates 5 to move closer or further apart, thereby adjusting the distance between the three top plates 5. The limiting piece 706 at the end of the toothed column 704 can limit the sliding stroke of the toothed column 704, preventing the toothed column 704 from disengaging from the transmission gear 702 or the guide block 703, and ensuring the reliability of the adjustment action.

[0032] like Figure 1 and Figure 7 As shown, the linkage assembly 23 includes a first side plate 2301 fixed on the central assembly frame 10. A rotating cylinder 2302 is rotatably connected inside the first side plate 2301. A fourth bevel gear 2303 that meshes with the third bevel gear 22 is fixedly connected to the rotating cylinder 2302. A second side plate 2304 is fixedly connected to each of the two outer assembly frames 10. A connector 2305 is rotatably connected to the second side plate 2304. A fifth bevel gear 2306 that meshes with the third bevel gear 22 is fixedly connected to each connector 2305. Splined shafts 2307 are slidably connected to both ends of the rotating cylinder 2302. The outer ends of the splined shafts 2307 are fixedly connected to the connectors 2305 respectively.

[0033] The rotation of the drum 2302 will drive the spline shaft 2307 to rotate, and the rotation of the spline shaft 2307 will drive the connector 2305 to rotate synchronously. At the same time, the fourth bevel gear 2303 on the drum 2302 and the fifth bevel gear 2306 on the connector 2305 will mesh with the third bevel gear 22 on the three assembly frames 10 respectively. When the drum 2302 rotates, it will drive the rotating shaft 20 on the three assembly frames 10 to rotate synchronously, thereby realizing the synchronous action of the positioning switching mechanism on the three assembly frames 10, ensuring that the positioning components at the three positions switch the adsorption mode at the same time, and ensuring the stability and consistency of the positioning of the welded parts.

[0034] like Figure 1 and Figure 7As shown, a worm gear 2308 is fixedly connected to the rotating drum 2302. A base 2309 is provided on the lower side of the worm gear 2308. The base 2309 is fixedly connected to the central assembly frame 10. A third motor 2310 is fixedly connected to the lower end face of the base 2309. The drive end of the third motor 2310 passes through the base 2309 and is fixedly connected to a worm 2311 that meshes with the worm gear 2308.

[0035] The worm gear 2311 is driven to rotate by the third motor 2310. The rotation of the worm gear 2311 will drive the worm wheel 2308 to rotate, and the rotation of the worm wheel 2308 will drive the rotating drum 2302 to rotate, thus providing power to the linkage component 23.

[0036] like Figure 1 and Figure 4 As shown, the flipping assembly 24 includes two symmetrical mounting bases 2401 fixed on the mounting plate 3. A second telescopic cylinder 2402 is rotatably connected to each of the two mounting bases 2401. A movable block 2403 is rotatably connected to the drive end of the second telescopic cylinder 2402. The bottom end of the movable block 2403 is fixedly connected to the upper end face of the connecting plate 4.

[0037] When the second telescopic cylinder 2402 extends or retracts, the connecting plate 4 is pushed or pulled by the movable block 2403, causing the connecting plate 4 to rotate around the rotating connection with the mounting plate 3, thereby adjusting the tilt posture of the lower positioning mechanism to ensure that the welded parts can be positioned at an angle that fits the hull wall, thus improving the welding accuracy.

[0038] like Figure 3 and Figure 6 As shown, each assembly plate 9 has two vacuum chucks 17 and two electromagnets 18, and the two vacuum chucks 17 and two electromagnets 18 are designed diagonally.

[0039] like Figure 3 As shown, each assembly plate 9 has two switching plates 12, and the two switching plates 12 are tilted in opposite directions.

[0040] Specifically, in use, the present invention works as follows: First, the workpiece to be positioned is placed on the side of the guide rail 209 away from the hull. Then, adjustments are made according to the material and size of the workpiece. If the adsorption head needs to be switched, the third motor 2310 drives the worm gear 2311 to rotate. The rotation of the worm gear 2311 drives the worm wheel 2308 to rotate. The rotation of the worm wheel 2308 drives the rotating drum 2302 to rotate. The rotation of the rotating drum 2302 drives the spline shaft 2307 to rotate. The rotation of the spline shaft 2307 drives the connector 2305 to rotate synchronously. At the same time, the fourth bevel gear 2303 on the rotating drum 2302 and the fifth bevel gear 2306 on the connector 2305 respectively... The third bevel gear 22 on the three assembly racks 10 meshes with the third bevel gear 22, which in turn rotates. The rotation of the third bevel gear 22 drives the rotating shaft 20 and the second bevel gear 21 to rotate. The rotation of the second bevel gear 21 drives the first bevel gear 19 to rotate simultaneously, which in turn drives the rotating rod 11 to rotate. When the rotating rod 11 rotates, the switching plate 12 drives the sliding column 14 through the sliding port 13 to drive the lifting column 15 to move up and down along the guide sleeve 16. Since the two switching plates 12 are tilted in opposite directions, when the rotating rod 11 rotates, the two diagonally opposite lifting columns 15 will descend synchronously and the other two diagonally opposite lifting columns 15 will rise synchronously, realizing the switching operation between the vacuum suction cup 17 and the electromagnet 18. When the servo motor 701 drives the transmission gear 702 to rotate, it will drive the two gear columns 704 to slide synchronously in opposite directions along the guide block 703. Then, through the fixed seat 705, it will drive the two outer top plates 5 to move closer or further apart, thereby adjusting the distance between the three top plates 5. Then, the first telescopic cylinder 601 is activated to extend and retract, causing the vacuum suction cup 17 or electromagnet 18 to descend to the surface of the weldment and fix it. Then, the first telescopic cylinder 601 retracts, and the first motor 203 drives the turntable 202 to rotate, causing the column 1 and the fixed weldment to rotate to the side closer to the hull. Then, when the second telescopic cylinder 2402 is activated to extend and retract, the movable block 2403 pushes or pulls the connecting plate 4, causing the connecting plate 4 to rotate around the rotating connection with the mounting plate 3, thereby adjusting the tilt posture of the lower positioning mechanism to ensure that the weldment can be positioned at an angle that fits against the hull wall. Then, the second motor 208 drives the roller 207 to move on the guide rail 209 to adjust the weldment to the welding position. At the same time, the first telescopic cylinder 601 extends to move the weldment to the welding position to achieve welding positioning.
