Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a positioning mobile welding device for shipbuilding. Background Art

[0002] Shipbuilding includes steps such as material preparation, segment manufacturing, outfitting, launching and delivery. Among them, welding technology is required in the segment manufacturing and outfitting steps. In order to improve welding efficiency, mobile welding equipment is used to move according to the arranged workpiece position and perform welding operations. Currently, common mobile welding equipment includes horizontal moving position welding equipment.

[0003] Before the current horizontal movement and displacement welding equipment is processed, multiple workpieces to be welded are arranged and placed on a workbench, and clamps or other fixing devices are used to ensure that the ship workpieces are stable and immobile. Then, the position of the ship workpiece is adjusted according to the welding requirements to achieve the optimal welding angle or position, and the welding path is pre-programmed through the automation system, and then the welding operation is performed by the welding robot. However, the use of clamps to position and limit the ship workpiece is suitable for processing a small number of ship workpieces. When the number of ship workpieces to be processed is large, a large number of clamps are required, and the clamping and positioning of loading and unloading one by one is not conducive to improving the welding efficiency. Secondly, the welding equipment moves and displaces horizontally when welding two adjacent ship workpieces. The unlocked welding equipment will shake as the welding robot moves during the welding process. However, the welding accuracy requirements for ship workpieces are high, and the stability of the welding equipment and ship workpieces needs to be improved.

[0041] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The locking mechanism 4 includes an electric push rod 41, and the left and right top walls of the circular support frame 32 are symmetrically installed with the electric push rods 41.

The circular support frame 32 and the pressing frame 42 are commonly provided with a buffer component 44 for reducing vibration during welding.

[0042] Reference Figure 1 , Figure 2 and Figure 6 The driving assembly 43 includes a pressing protrusion 431, and the bottom wall of the pressing frame 42 is symmetrically fixedly connected with the pressing protrusion 431, and the bottom wall of the pressing protrusion 431 is inclined. The top wall of the circular support frame 32 slides left and right with an L-shaped slide 432 symmetrically distributed left and right, and the L-shaped slide 432 and the top wall corresponding to the pressing protrusion 431 above and below are inclined to match it; the two vertical sections of the inverted U slide 25 are penetrated by hole position 1 434 on the left and right, and the slide rail 2 24 is evenly distributed from front to back with multiple hole positions 435 that are penetrated by the left and right, and the hole position 435 corresponds to the hole position 1 434, and the side wall of the vertical section of the L-shaped slide 432 is fixedly connected with a locking pin 433 that is compatible with the hole position 1 434 and the hole position 2 435.

[0043] Reference Figure 6 to Figure 7The buffer assembly 44 includes a downward pressure rod 441. The left and right sections of the circular support frame 32 are symmetrically connected to the spring telescopic rod 442 through a spring three (not shown in the figure) with the locking pin 433 as the center, and are slidably connected to the spring telescopic rod 442 up and down. The bottom wall of the telescopic end of the spring telescopic rod 442 is fixedly connected to a rubber gasket 444. A buffer spring 443 is sleeved and connected between the bottom wall of the fixed end of the spring telescopic rod 442 and the top wall of the rubber gasket 444. The left and right bottom walls of the downward pressure frame 42 are fixedly connected to multiple downward pressure rods 441 corresponding to the spring telescopic rod 442 up and down.

[0044] The sliding frame 31 is driven by the electric slider to slide upward and adjust on the inverted U slide 25. When the sliding frame 31 drives the circular support frame 32 to move downward from the upper side of the ship workpiece until the bottom wall of the circular support frame 32 is in contact with the top wall of the operating table 1, the circular support frame 32 is located on the outside of the workpiece to be welded.

[0045] The up and down adjustment frame 331 slides upwards driven by the electric slider, driving the four wedge blocks 332 to move upwards synchronously, the inclined surface of the wedge block 1 332 is in contact with the inclined surface of the wedge block 2 333, and gradually pushes the wedge block 2 333 to move horizontally, the wedge block 2 333 drives the connecting plate 1 334 away from the inner wall of the circular support frame 32, and the four connecting plates 1 334 move synchronously toward the direction of the ship workpiece, and the ship workpiece is centered in the four directions of front, back, left and right through the positioning accessories 343, and is stably limited to ensure that the ship workpiece is in the correct position during welding operations.

[0046] The positioning accessory 343 is a clamping piece of different shapes that can be engaged and connected with the connecting plate 2 342. Before the welding operation, the positioning accessory 343 is selectively installed according to the type of regular ship workpiece to be welded. As the connecting plate 1 334 moves, the positioning accessory 343 gradually fits closely to the side wall of the ship workpiece.

[0047] The adaptive link 341 moves between the connecting plate 1 334 and the connecting plate 2 342 to approach the ship workpiece. When the length and width of the ship workpiece are inconsistent, the adaptive link 341 is adaptively deflected outside the hollow rod 351, and the telescopic end is adaptively telescoped on the fixed section. The telescopic end of the adaptive link 341 and the torsion spring rod connected to the connecting plate 1 334 and the connecting plate 2 342 are adaptively rotated to adjust the distance between the connecting plate 2 342 and the connecting plate 1 334. The fixed section of the adaptive link 341 is adaptively telescopically adjusted to its position with the connecting plate 1 334 through the telescopic plate, so as to facilitate adaptation to ship workpieces with different lengths and widths and increase the practicability of the equipment.

[0048] After the positioning of the ship workpiece is completed, the top wall of the output end of the plurality of electric push rods 41 moves downward to drive the pressing frame 42 to move downward. When the pressing frame 42 moves downward and approaches the circular support frame 32, the pressing protrusion 431 and the pressing rod 441 are driven to move downward.

[0049] During the downward movement of the pressing protrusion 431, the inclined surface of the pressing protrusion 431 is in close contact with the inclined surface of the L-shaped slide 432, and gradually pushes the L-shaped slide 432 to slide on the circular support frame 32, and the L-shaped slide 432 drives the locking pin 433 to approach the corresponding inverted U slide 25 and the slide rail 24, and the locking pin 433 gradually penetrates the corresponding hole position 1 434 and the hole position 2 435, and the circular support frame 32 is connected with the slide rail 2 24 and the inverted U slide 25 through the locking pin 433 to realize the synchronous locking of the position between the operating table 1, the moving mechanism 2 and the positioning mechanism 3, which is beneficial to enhance the stability of the welding operation.

[0050] The lower pressure rod 441 moves downward and gradually comes close to the top wall of the spring telescopic rod 442, and pushes the fixed section of the spring telescopic rod 442 to slide downward on the circular support frame 32 until the rubber gasket 444 comes close to the top wall of the operating table 1. When vibration occurs during the welding process, the telescopic end of the spring telescopic rod 442 is adaptively extended and retracted, and the buffer spring 443 is adaptively compressed and rebounded to buffer the welding stress and improve the accuracy and quality of welding.

[0051] The lower pressing frame 42 moves downward and gradually comes close to the top wall of the upper and lower sliding rods 352, and pushes the upper and lower sliding rods 352 to move downward inside the hollow rod 351. When the upper and lower sliding rods 352 move downward, the inclined surface of the wedge block three 353 comes close to the inclined surface of the wedge block four 355, and pushes the wedge block four 355 to move. The wedge block four 355 drives the arc plate 354 to slide from the inside of the hollow rod 351 to the outside of the hollow rod 351. A hole matching the hollow rod 351 is provided in the middle of the fixed section of the adapting connecting rod 341. The side wall of the arc plate 354 gradually comes close to the hole in the middle of the fixed section of the adapting connecting rod 341. The offset angle of the adapting connecting rod 341 is locked by the arc plate 354, which is beneficial to maintaining the stability of the positioning of the ship workpiece. The side wall of the arc plate 354 is made of rubber, which is beneficial to increase the friction between the adapting connecting rod 341 and the adapting connecting rod 341.

[0052] When the welding of the previous ship workpiece is completed, the sliding frame 31 is driven by the electric slider to slide upward on the inverted U slide 25 for adjustment. Before welding the next ship workpiece, the sliding frame 31 is driven by the electric slider to slide continuously downward on the inverted U slide 25 for adjustment.

[0053] The specific operation steps of this shipbuilding positioning mobile welding equipment are as follows:

[0054] The sliding seat 22 drives the welding robot arm 23 to slide from front to back on the slide rail 1 21. The movement of the sliding seat 22 drives the inverted U slide 25 and the sliding frame 31 to slide from front to back on the slide rail 2 24. The ship workpieces arranged on the operating table 1 are positioned in sequence by the positioning mechanism 3 and then welded by the welding robot arm 23.

[0055] When the sliding frame 31 drives the circular support frame 32 to be located outside the workpiece to be welded, the upper and lower adjustment frames 331 slide upward to drive the four connecting plates 1 334 to move synchronously toward the direction of the ship workpiece, and the ship workpiece is centered in the four directions of front, back, left and right through the positioning accessories 343, and is stably limited; the adaptive connecting rod 341 adapts the distance between the connecting plate 2 342 and the connecting plate 1 334 according to the different lengths and widths of the ship workpieces, thereby increasing the practicability of the equipment.

[0056] The electric push rod 41 drives the pressing frame 42 to move downward, and the pressing protrusion 431 drives the locking pin 433 to gradually penetrate the corresponding hole position 1 434 and hole position 2 435, so as to synchronously lock the positions among the operating platform 1, the moving mechanism 2 and the positioning mechanism 3; the pressing rod 441 drives the rubber gasket 444 to press against the top wall of the operating platform 1, and when vibration occurs during welding, the spring telescopic rod 442 and the buffer spring 443 buffer the welding stress; the pressing frame 42 moves downward to drive the upper and lower sliding rods 352 to move downward, and the wedge block 455 drives the arc plate 354 to slide against the hole in the middle of the fixed section of the adapting connecting rod 341, and the offset angle of the adapting connecting rod 341 is locked by the arc plate 354 to maintain the positioning stability during processing.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept 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.
