[0002] Thick-plate titanium alloy containers are commonly used in demanding industrial applications, particularly in aerospace, chemical, marine engineering, and high-temperature, high-pressure environments. Titanium alloys are characterized by excellent corrosion resistance, strength-to-weight ratio, and high-temperature resistance, enabling them to perform exceptionally well under extreme conditions. In the manufacturing of titanium alloy containers, the connection between the container body and other components is generally achieved through welding. Various welding processes are available, with automatic and semi-automatic arc welding being commonly used. The connection between the pipe end and the container body is a frequent welding task. During welding, the tooling supporting the container needs adjustment to ensure proper installation and facilitate subsequent operations. However, existing tooling adjustment methods are inconvenient and have limited functionality, failing to meet processing requirements.

A clamping part 30 is provided on the telescopic rod of the clamping electric cylinder 29. The clamping part 30 is used to clamp the parts connected to the container.
[0029] Operating principle: The container body is installed on the positioning seat 4. Before installation, the flipping frame 5 and the positioning seat 4 are in an open state to facilitate container installation. The position of the positioning roller 32 can be adjusted according to the size of the container. Specifically, by controlling the motor 31, the control semi-circular ring 34 and the control gear ring 35 are rotated, which in turn rotates the clamping gear 40. This controls the clamping state of the electromagnetic telescopic clamping plate 41 on the spiral sleeve 39, making the spiral sleeve 39 rotate synchronously with the clamping gear 40. During adjustment, the control semi-circular ring 34 rotates at a preset angle, and through forward and reverse rotation, as well as the clamping control of the electromagnetic telescopic clamping plate 41 on the spiral sleeve 39, the telescopic screw 38 and the telescopic frame 36 move continuously in one direction, thereby adjusting the positioning roller 32. The radial position of the container is adjusted to fit the container size. The screw 3 is driven by motor 2 to rotate, causing the two positioning seats 4 to move. That is, the position is adjusted according to the length of the container. The two ends of the container are located on the positioning seats 4, and the middle area is located on the support roller 17 for support. The position is adjusted by the screw 11 driven by motor 9 to rotate and the slide 12 to move. The support seat 14 is moved by hydraulic cylinder 13, and the position of the support roller 17 is controlled by hydraulic cylinder 15 to fit the size of the container. Furthermore, after the container is positioned and installed, if the position needs to be adjusted, the slide 12 can be moved and the container moves with the slide 12. The end of the container is on the positioning roller 32, and the ball bearings on the positioning roller 32 allow the container to move axially.
[0030] Furthermore, the support roller 17 is driven to rotate by the support motor 18, thereby causing the container to rotate. The flipping frame 5 and the positioning seat 4 are in a closed docking state. The control cylinder 6 controls the contact part 7 to contact the container surface. As the container rotates, the contact part 7 can extend and retract when it contacts the container surface. The position sensor outputs a displacement signal of the contact part 7 to check whether there are defects such as pits or protrusions in the container positioning and installation area.
[0031] The pipe end component is installed on the connecting frame 23, and the clamping part 30 is clamped and fixed by the clamping electric cylinder 29. The motor 3 21 drives the lead screw 3 20 to move, so that the connecting frame 23 moves, that is, the pipe end component is connected to the end of the container body. Multi-degree-of-freedom welding is performed by the welding arm 28, and the orientation of the welding arm 28 can be adjusted by the angle motor 25 driving the gear ring 27 to rotate.
