[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0038] like Figure 1As shown, the present application provides a metal tank body welding device, which has a tank shell 5 and a tank cover 6 that need to be welded, and the tank shell 5 and the tank cover 6 can be assembled. The welding device includes a welding table 1, and the welding table 1 has a base plate 11, and the base plate 11 is used to place and install the welding structure. A support seat 12 is fixedly installed at the lower end of the base plate 11, and the stability of the welding structure on the base plate 11 is ensured by the support seat 12.

[0039] The welding mechanism 3 has a fixing mechanism 2 installed on the bottom plate 11, and the fixing mechanism 2 is used to support and fix the tank shell 5. At the same time, a clamping mechanism 4 is arranged on one side of the fixing mechanism 2, and the clamping mechanism 4 is arranged opposite to the fixing mechanism 2. The clamping mechanism 4 is used to fix the tank cover 6 and align the tank cover 6 with the tank shell 5 for splicing. In addition, a welding mechanism 3 is arranged on one side of the fixing mechanism 2 and the clamping mechanism 4, and the welding mechanism 3 is used to weld the gap after the tank cover 6 and the tank shell 5 are spliced.

[0040] The clamping mechanism 4 has a clamping jaw 41, which is a pneumatic clamping jaw in the prior art and will not be described in detail here. A fixing column 42 is fixedly installed at the lower end of the clamping jaw 41, and a slider 44 is fixedly installed at the lower end of the fixing column 42. At the same time, a slide rail 43 is fixedly installed at the upper end of the bottom plate 11, and the slide rail 43 is located below the fixing column 42. The slide rail 43 is slidably connected with the slider 44;

[0041] In addition, a first bolt 45 is threadedly connected to the slider 44, so the clamping jaw 41 can be fixed by tightening the first bolt 45. If the position of the clamping jaw 41 needs to be adjusted, the first bolt 45 is loosened at this time, and the fixing column 42 is manually pushed to slide on the slide rail 43 until it is adjusted to a suitable position, and finally the first bolt 45 is tightened.

[0042] like Figure 2-Figure 3 As shown, the fixing mechanism 2 has a baffle 21, which is fixedly mounted on the upper end of the bottom plate 11, and a first cylinder 22 is rotatably connected to the baffle 21, and an adjusting rod 23 is fixedly mounted on the output shaft of the first cylinder 22, and a fixing shell 26 is fixedly mounted on one end surface of the first cylinder 22 close to the adjusting rod 23, and the fixing shell 26 penetrates the adjusting rod 23, so the first cylinder 22 can drive the adjusting rod 23 to perform telescopic activities without affecting the fixing shell 26;

[0043] At the same time, a connecting plate 24 is fixedly installed at one end of the adjusting rod 23 away from the first cylinder 22, and a clamping member is arranged on the connecting plate 24. The clamping member is provided with two groups and is respectively installed on both sides of the connecting plate 24. The two groups of clamping members are respectively a first clamping member 25 and a second clamping member 27. It should be noted that the first clamping member 25 and the second clamping member 27 have the same structure. The first clamping member 25 is taken as an example for description below.

[0044] Specifically, the first clamping member 25 has a connecting column 252 hinged on the connecting plate 24, and the other end of the connecting column 252 is hinged to a movable column 251, and one end of the movable column 251 away from the connecting column 252 is hinged to the fixed shell 26;

[0045] At the same time, an arc plate 253 is fixedly installed on the outer side of the connecting end of the movable column 251 and the connecting column 252. Therefore, starting the first cylinder 22 can drive the adjusting rod 23 and the connecting plate 24 to move, thereby moving the movable column 251 and the connecting column 252 to adjust the position of the arc plate 253 until the arc plate 253 is attached to the inner wall of the tank shell 5, thereby fixing the tank shell 5.

[0046] like Figure 1 As shown, the welding mechanism 3 has a telescopic column 32, which is rotatably connected to the upper end of the bottom plate 11. The telescopic column 32 can be telescoped, and a welding head 31 is arranged at the upper end of the telescopic column 32. The welding head 31 is located above the fixing mechanism 2. The welding head 31 is a prior art and is used to weld the tank cover 6 and the tank shell 5. Therefore, the height of the welding head 31 can be adjusted by the telescopic column 32, and the telescopic column 32 can also be rotated to adjust the position of the welding head 31 to weld metal tanks of different sizes.

[0047] In the present application, a drive motor (not shown) is fixedly installed at one end of the baffle 21 away from the fixing mechanism 2, and the output shaft of the drive motor is fixed to the rear end of the first cylinder 22. Therefore, when the welding head 31 completes welding of the partial gap after the tank cover 6 and the tank shell 5 are assembled, the clamping jaws 41 are slightly loosened at this time, and then the drive motor is started, which can drive the tank shell 5 and the tank cover 6 to rotate as a whole, and weld the gaps of other parts.

[0048] In summary, when installing the tank body to be welded, first loosen the first bolt 45, then push the clamping jaw 41 away from the fixing mechanism 2, then sleeve the tank shell 5 on the fixing mechanism 2, and start the first cylinder 22 to make the arc plate 253 stick to the inner wall of the tank shell 5, so as to fix the tank shell 5;

[0049] At this time, the tank cover 6 is fixed on the clamp 41, and the tank cover 6 is adjusted toward the tank shell 5 until it is assembled with the tank shell 5. Then, the welding head 31 is adjusted to the joint gap between the tank cover 6 and the tank shell 5, and they are welded. In this way, the metal tank body is fixed by the fixing mechanism 2 and the clamp 41, thereby improving the flexibility of the welding device and facilitating adaptation to metal tank bodies of different sizes without replacing the installation sleeve or setting a larger installation sleeve.

[0050] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
