When the tank body needs to be transported inward, the user can start the moving component to move the two tank bodies located on the top of the driving wheel. When the internal processing component and the external processing component move to the position of the moving component, the moving component descends without interfering with the external processing component. In order to improve the stability of the device, when the user sets the tank body on the outside of the second electric slide rail, the user drives the lifting head to be hidden inside the side panel through the electric push rod. At this time, the internal processing component is located on the second electric slide rail. One end close to the positioning component reduces the burden of the second electric slide rail.

At this time, the first tank body and the second tank body become a whole; When clamping the device, the user can start the inner clamping piece to clamp the inner wall of the tank body to prevent the tank body from being deformed due to excessive welding temperature during welding, improve the stability of welding, prevent the tank body from being dislocated and affecting the welding quality. After the clamping is completed, when it is necessary to weld the inside, the user starts the inner welding piece to make it move in a circular motion on the outside of the inner annular fixing ring, and at the same time starts the inner automatic welding gun to weld the welding part. The wiping cotton is in contact with the inner annular fixing ring to prevent dust from entering the interior of the inner welding piece and affecting the internal parts. In order to prevent dust from entering the interior of the inner gear ring and causing the device to jam, the cleaning piece rotates from the inside to the outside to clean the dust that falls into the interior of the inner gear ring out of the movable ring to prevent dust from accumulating inside the inner gear ring and affecting the operation of the device.

[0017] When the outside of the tank body needs to be processed, the user moves the external fixing part to the outside of the welding part and starts the main cylinder installed inside the external fixing part. The pneumatic push rod drives the fixing plate at its end to extend outward, thereby fixing the outside of the second tank body. Since the first tank body has been fixed by the positioning assembly, after the second tank body is fixed, the first tank body and the second tank body can be relatively fixed to prevent misalignment. Then the user starts the external welding part to drive the internal clamping part to move in a circle around the side of the external fixing part, and at the same time starts the external automatic welding gun, which welds the welding part on the outside of the tank body.

[0031] A fluorine-lined storage tank installation welding method, according to the above fluorine-lined storage tank installation welding device, the specific steps are as follows: Step 1: First, the tank body of one of the fluorine-lined storage tanks is sleeved on the outside of the second electric slide rail 104 and placed into the device through the side plate 102; Step 2: Use the moving assembly 005 to move the fluorine-lined storage tank through the internal processing assembly 003 and the external processing assembly 004 and transport it to a position that fits with the positioning assembly 002, and push the tank upward to a position that fits with the positioning assembly 002 according to the diameter of the tank; Step 3: Clamp and fix the tank body by positioning component 002; Step 4: Put another tank into the device again, and transport it to a position opposite to the first tank through the moving component 005; Step 5: Clamp and fix the sides of the welding parts of the two tanks by starting the inner clamping member 320 and the pneumatic push rod 415; Step 6: Start the internal processing component 003 and the external processing component 004 to weld the inside and outside of the tank.

[0032] Embodiment 2

[0033] The difference from the first embodiment is that the overall support 001 is placed vertically, and there is no moving component 005 and lifting component 006; When the tank body to be welded is too heavy, the user can place the device vertically, directly put the first tank body to be welded inside the second electric slide rail 104, and directly place it on the top of the mounting plate 201, clamp the first tank body by starting the positioning component 002, and then put the second tank body on the top of the second electric slide rail 104 in the same way, and then the user can clamp the second tank body through the internal processing component 003 and the external processing component 004, and drive the internal processing component 003 and the external processing component 004 to move through the second electric slide rail 104 and the first electric slide rail 103, so that the two tank bodies are docked, and since the internal processing component 003 and the external processing component 004 and the positioning component 002 are all coaxially arranged, the two tank bodies can be accurately docked, and then the inner and outer sides of the tank bodies can be directly welded through the internal processing component 003 and the external processing component 004.
