Obviously, the described embodiments are 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 making creative work are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in , 3, in this embodiment, a pressure vessel riveting and welding positioning tool is proposed, comprising two fixing seats 1, a first side plate 2 and a second side plate 3 are arranged between the two fixing seats 1, and the first side plate 2 and the second side plate 3 are rotatably connected to the two fixing seats 1 respectively;

[0023] A fixed bracket 6 and a movable bracket 8 are provided between the first side plate 2 and the second side plate 3, the two ends of the fixed bracket 6 are fixedly connected to the first side plate 2 and the second side plate 3 respectively, the movable bracket 8 is placed above the fixed bracket 6, and a lifting mechanism for adjusting the height of the movable bracket 8 is provided on the second side plate 3;

[0024] A side thrust plate assembly for fixing the pressure vessel is disposed on the side of the second side plate 3 facing the first side plate 2 , and a rotating driving member for controlling the rotation of the first side plate 2 is disposed at the connection between the first side plate 2 and the fixing seat 1 .

[0025] The pressure vessel to be riveted is placed between the fixed bracket 6 and the movable bracket 8, and the side push plate assembly pushes the container from the side of the container to fix the container between the first side plate 2 and the second side plate 3;

[0026] The lifting mechanism pushes the movable bracket 8 to fall down, and after falling down, the movable bracket 8 cooperates with the fixed bracket 6 to limit the container again from the bottom and top of the container, and has good stability;

[0027] After the fixation is completed, the first side plate 2 is controlled to rotate by the rotating driving member, and the fixed container between the first side plate 2 and the second side plate 3 can also rotate accordingly, so that the riveting and welding equipment can weld different areas of the container conveniently;

[0028] After welding is completed, the movable bracket 8 and the second V-fork 9 are released, the fixing of the container by the side push plate assembly is released, and the first side plate 2 is rotated to automatically pour out the container, and unloading is quick and convenient.

[0029] Specifically, the movable bracket 8 is provided with a plurality of second V-forks 9, which are fixedly connected to the movable bracket 8, and the fixed bracket 6 is provided with a plurality of first V-forks 7, which are fixedly connected to the fixed bracket 6. The first V-forks 7 on the fixed bracket 6 support and limit the container from the lower half of the container, and the movable bracket 8 falls under the push of the lifting mechanism to fix the container, and the second V-forks 9 on the movable bracket 8 limit the container from the upper half of the container to prevent the container from shaking up and down.

[0030] It is worth further explaining that each second V-fork 9 is staggered with each first V-fork 7. The purpose of the staggered setting is that when the movable bracket 8 slides downward, the second V-fork 9 fixed to the movable bracket 8 will not conflict with the first V-fork 7 fixed to the fixed bracket 6, and the second V-fork 9 can cooperate with the first V-fork 7 to limit the smaller size of the container.

[0031] About lifting mechanism:

[0032] The lifting mechanism includes an adjusting plate 10 and a first motor 11. The adjusting plate 10 is fixedly connected to the upper end of the second side plate 3.

The screw 12 is rotatably connected to the adjusting plate 10. A matching block 14 is sleeved on the outside of the screw 12. The matching block 14 is threadedly connected to the screw 12. The matching block 14 is fixedly connected to one end of the movable bracket 8 close to the second side plate 3. The first motor 11 is installed on the outside of the adjusting plate 10, and the output end of the first motor 11 is fixedly connected to the screw 12.

[0033] The lifting mechanism adopts a screw transmission method to adjust the height of the movable bracket 8. Specifically, the first motor 11 drives the screw 12 to rotate, and the screw 12 cooperates with the matching block 14 during rotation, driving the matching block 14 to move along the rod of the screw 12. Since the matching block 14 is fixed to the movable bracket 8, the movable bracket 8 will also move when the matching block 14 moves, and the movable bracket 8 will rise and fall with it.

[0034] In order to improve the stability of the movable bracket 8 during the lifting and lowering process, in the preferred scheme, a limit plate 15 is provided at the upper end of the first side plate 2, and a slide groove 16 is provided on the side of the limit plate 15 facing the movable bracket 8, and a limit rod 17 is provided in the slide groove 16, and the limit rod 17 is fixedly connected to the limit plate 15, and a slider 18 is sleeved on the outer side of the limit rod 17, and the slider 18 is slidably connected to the limit rod 17, and the slider 18 is fixedly connected to the end of the movable bracket 8 away from the second side plate 3.

[0035] When the movable bracket 8 is rising or falling, the slider 18 fixedly connected to the other end of the movable bracket 8 will slide along the slide groove 16 and the rod body of the limiting rod 17. The limiting rod 17 cooperates with the slider 18 to limit the movable bracket 8 from the other end of the movable bracket 8, so that the movable bracket 8 will not tilt when rising or falling.

An opening is provided on the fixed seat 1 to allow the electric push rod 5 to rotate. The output end of the electric push rod 5 is rotatably connected to the movable plate 4.

[0038] The pressure vessel is placed between the fixed bracket 6 and the movable bracket 8, between the movable plate 4 and the first side plate 2, the electric push rod 5 pushes the movable plate 4, the movable plate 4 cooperates with the first side plate 2 to fix the container between the two, and then the movable bracket 8 fixes the container for the second time by falling.

[0039] For the specific structure of the side thrust plate assembly, please refer to the following description.
