[0023] Embodiment 1

[0024] like Figure 1-3 As shown, the utility model proposes an automatic welding device for a gas tank, which cooperates with a gas tank 4. A vent 1 401 is symmetrically provided at the side wall of the gas tank 4, and a vent 2 402 is symmetrically provided at both ends. The automatic welding device for a gas tank includes a base 1, a limit assembly 5 and a welding assembly 6. A support rod 2 is provided at the upper end of the base 1; a bottom bracket 3 for supporting the gas tank 4 is provided at the upper end of the support rod 2. The limit assembly 5 is arranged around the bottom bracket 3 to clamp and fix the gas tank 4. The welding assembly 6 is arranged on both sides of the bottom bracket 3 to weld the welds on both sides of the gas tank 4. The limit assembly 5 includes a driving member 51, a transverse limit assembly 52 and a longitudinal limit assembly 53. The transverse limit assembly 52 is driven by the driving member 51, and is plugged in with the vent 1 401 to limit the side wall of the gas tank 4. The longitudinal limiting member 53 is driven by the driving member 1 51 and is plugged with the vent 2 402 to limit the two ends of the gas storage tank 4. The welding assembly 6 includes a driving member 2 61 and a welding member 62 driven by the driving member 2 61 to move around the weld to weld the gas storage tank 4.

[0025] Further explanation, the driving member 51 includes a driving mechanism 511 arranged at the upper end of the base 1, and the driving mechanism 511 is a motor; the driving end of the driving mechanism 511 is connected with a threaded rod 512; the top end of the threaded rod 512 is rotatably connected to the bottom bracket 3, and the threaded rod 512 is also threadedly connected with a lifting plate 513; the lifting plate 513 is slidably connected with the support rod 2. The transverse limiting member 52 includes a bracket 521 symmetrically arranged on both sides of the base 1; a sliding rod 522 is connected between the two brackets 521 and the bottom bracket 3; a sliding seat 523 is slidably connected to the sliding rod 522; a slide plate 524 is arranged at the upper end of the sliding seat 523; a clamping column 525 is connected to the end of the two slide plates 524 facing the bottom bracket 3; a connecting plate 527 is arranged between the sliding seat 523 and the lifting plate 513; the connecting plate 527 is rotatably connected with the sliding seat 523 and the lifting plate 513. The longitudinal limiting member 53 includes brackets 531 symmetrically arranged on both longitudinal sides of the base 1; the two brackets 531 are respectively connected to sliding rods 532 at opposite ends; the other ends of the sliding rods 532 are connected to limiting plates 533, on which sliding plates 534 are slidably connected; the ends of the two sliding plates 534 facing the base 3 are connected to clamping columns 535; connecting plates 536 are provided between the sliding plates 534 and the lifting plates 513; the connecting plates 536 and the sliding plates 534 and the lifting plates 513 are all rotatably connected. The lifting and lowering of the lifting plate 513 drives the clamping column 1 525 and the clamping column 2 535 to approach the gas tank 4, so that the clamping column 1 525 is inserted into the vent 1 401, and the clamping column 2 535 is inserted into the vent 2 402, so as to fix and limit the gas tank 4 as a whole, so as to prevent the position of the gas tank 4 from shifting during welding, resulting in the position and shape of the weld not meeting the requirements, thereby reducing the welding quality, further affecting the strength and sealing of the gas tank, and reducing the product quality of the gas tank.

[0026] Further explanation, the upper ends of the two sliding seats 523 are provided with clamping plates 526 for clamping the side walls of the gas tank 4; the end of the clamping plate 526 facing the bottom bracket 3 is provided with an arc groove matching the side walls of the gas tank 4. The gas tank 4 is clamped from both sides to further reinforce the gas tank 4 and ensure the welding quality.

[0027] Further, the clamping column 1 525 matches the vent 1 401, and the clamping column 2 535 matches the vent 2 402. This prevents the clamping column 1 525 from being too small compared to the vent 1 401 / the clamping column 2 535 from being too small compared to the vent 2 402, which makes it impossible to clamp the gas tank 4 tightly, causing the gas tank 4 to shake during welding.

[0028] Embodiment 2

[0029] like Figure 4As shown, the utility model proposes an automatic welding device for gas tanks. Compared with the first embodiment, the present embodiment further includes: the second driving member 61 includes two groups of brackets 3 611 symmetrically arranged on the lateral sides of the bottom bracket 3; each group of brackets 3 611 is rotatably connected with a rotating shaft 612; one end of the two rotating shafts 612 is connected with a second driving mechanism 613, and the side walls are symmetrically connected with gears 614; the second driving mechanism 613 is a motor; the two adjacent gears 614 are meshed and connected with a gear ring 615. The welding tool 624 can be driven to rotate around the gas tank 4 to weld the gas tank 4. The welding process is automated and mechanized, and manual welding is not required by the staff, which reduces the labor intensity of the staff. At the same time, the welding position can be accurately adjusted to facilitate the subsequent repair of the weld.

[0030] Further explanation, a support ring 616 is provided inside the gear ring 615 and is rotatably connected to the gear ring 615; support frames 617 are symmetrically provided on the support ring 616; and the other ends of the two support frames 617 are respectively connected to the bracket 3 611 on the corresponding side. The gear ring 615 can be supported to improve the stability of the welding tool 624 during welding, thereby improving the welding quality.

[0031] Further explanation, the welding member 62 includes a connecting block 621 disposed on the gear ring 615; one end of the connecting block 621 facing the weld of the gas storage tank 4 is connected to a driving mechanism 3 622, which is a motor; the driving end of the driving mechanism 3 622 is connected to a telescopic mechanism 623, which is a cylinder; the telescopic end of the telescopic mechanism 623 is connected to a welding tool 624. The gas storage tank 4 can be welded.

[0032] The working principle of the utility model is as follows: when working, the gas storage tank 4 is first placed on the base 3, so that the vent 1 401 is directly opposite to the clamping column 1 525, and the vent 2 402 is directly opposite to the clamping column 2 535. Then, the driving mechanism 1 511 is started to drive the threaded rod 512 to rotate, thereby driving the lifting plate 513 to descend, and then driving the connecting plate 1 527 and the connecting plate 2 536 to rotate. The connecting plate 1 527 rotates to drive the sliding seat 523 to slide along the sliding rod 1 522 toward the gas tank 4. The connecting plate 2 536 rotates to drive the sliding plate 2 534 to slide along the sliding rod 2 532 toward the gas tank 4, and finally the clamping column 1 525 is clamped into the vent 1 401, and the clamping column 2 535 is clamped into the vent 2 402. At the same time, the clamping plate 526 will clamp the gas tank 4 from both sides of the gas tank 4, thereby limiting and fixing the gas tank 4 to prevent the gas tank 4 from shifting in position during the welding process, thereby affecting the welding quality.

[0033] Then, the telescopic mechanism 623 is started to extend the welding tool 624 and align it with the weld, and then the driving mechanism 3 622 is started to drive the welding tool 624 to rotate and weld the gas tank 4. Finally, the driving mechanism 2 613 is started to drive the rotating shaft 612 and the gear 614 to rotate, thereby driving the gear ring 615 to rotate and complete the welding.

[0034] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
