[0032] Please refer to Figures 1-6 As shown in the utility model is a kind of three-station tank body automation welding equipment, including workbench 1, the workbench 1 top is fixedly installed with welding bin 2, the inner top of welding bin 2 is fixedly installed with support column 3, the support column 3 top is installed with taking and placing switching mechanism 4, taking and placing switching mechanism 4 both ends are equipped with taking and placing mechanism 5, first air cylinder 6 is installed on two taking and placing mechanism 5, the welding bin 2 bottom is installed with angle rotating mechanism 7, the inner chamber of welding bin 2 and located around angle rotating mechanism 7 is provided with three moving mechanisms 8, each moving mechanism 8 is fixedly installed with welding gun 9.

[0033] When the head and cylinder of the gas tank need to be welded, the worker usually places the cylinder on the top of the angle rotating mechanism 7, which can limit the inner ring of the cylinder, and places the head on the placing table (the height of the placing table is the same as the height of the cylinder placed on the angle rotating mechanism 7, which is not shown in the drawing). After the preparation work is completed, the taking and placing switching mechanism 4 drives the two end taking and placing mechanisms 5 to rotate, so that one of the taking and placing mechanisms 5 rotates to the top of the head on the placing table, and then the taking and placing mechanism 5 is started. The taking and placing mechanism 5 pushes it to move downward, and after contacting with the head, it continues to press down, and the taking and placing mechanism 5 and the head are stably fixed by interference fit. Then, the taking and placing switching mechanism 4 drives the two taking and placing mechanisms 5 to rotate, and rotates the taking and placing mechanism 5 with the head to the top of the cylinder. At this time, the other taking and placing mechanism 5 rotates to the top of the next head to be welded on the placing table. Then, the two taking and placing mechanisms 5 act synchronously, the taking and placing mechanism 5 with the head vertically descends to accurately place the head on the top of the cylinder, and the taking and placing mechanism 5 without the head descends to grab the head on the placing table. After positioning is completed, the three moving mechanisms 8 are started simultaneously to drive the welding guns 9 to move to the weld between the head and the cylinder. Then, the welding guns 9 weld the weld, and at the same time, the angle rotating mechanism 7 starts to rotate to drive the cylinder and the head to rotate synchronously. Because the head and the taking and placing mechanism 5 are interference fitted, the corresponding parts in the taking and placing mechanism 5 also rotate. The three welding guns 9 weld the weld, and under the cooperation of the angle rotating mechanism 7, the head and the cylinder are completely welded to firmly connect them. After welding is completed, the angle rotating mechanism 7 stops working, and at this time, the first cylinder 6 is started to push the welded head, so that the first cylinder 6 and the taking and placing mechanism 5 move upward and separate from the head. Then, the worker takes out the welded head and the cylinder from the angle rotating mechanism 7, and places a new cylinder to be welded in the angle rotating mechanism 7. The angle rotating mechanism 7 positions it, and then the taking and placing switching mechanism 4 is started again to rotate the taking and placing mechanism 5 with the head to the top of the cylinder.
