[0002] Pressure vessel manufacturing technology refers to the equipment manufacturing technology used to store or transport liquids, gases, steam and other media in industrial production. The development of pressure vessel manufacturing technology is not only related to production efficiency and quality, but also directly related to safety and environmental protection in industrial production. Pressure vessel manufacturing technology needs to strictly abide by relevant standards and specifications to ensure the safety and reliability of products.

[0003] At present, traditional support devices usually use metal pressure or clamping structures to pressurize and clamp the container surface during use, so as to improve the stability of the container support. However, pressure vessels are all thin-walled shells. When traditional support devices use pressure plates or clamping plates to apply force to the outside of the pressure vessel, it is easy to cause dents and damage to the pressurized area, which in turn affects the quality of the finished product of the pressure vessel and reduces manufacturing efficiency.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in this embodiment, a support tool for manufacturing a pressure vessel includes a base plate 1, the top of the base plate 1 is fixedly connected to a support seat 2, the top of the support seat 2 is provided with an arc-shaped support groove 3, the interior of the arc-shaped support groove 3 is provided with an air bag 4, both sides of the support seat 2 are fixedly installed with air pumps 5, the output ends of the two air pumps 5 are fixedly connected to the air bag 4, the top of the base plate 1 is slidably connected to two movable plates 7, the top of the base plate 1 and on both sides of the support seat 2 are provided with displacement components, the displacement components are used to drive the two movable plates 7 to move, a side groove 15 is provided on one side of the movable plate 7, the interior of the side groove 15 is fixedly connected with an arc-shaped support plate 8, and the inner side of the arc-shaped support plate 8 is provided with a rubber gasket 16.

[0021] When using the support fixture, first place the pressure vessel inside the arc-shaped support groove 3, then inject air into the airbag 4 through two air pumps 5 to expand the airbag 4 and make it contact with the outside of the pressure vessel, then use the displacement assembly to drive the two moving plates 7 to move to both sides of the pressure vessel, so that the arc-shaped support plate 8 in the side groove 15 is in contact with the outside of the pressure vessel, and the rubber gasket 16 is fitted with the outside of the pressure vessel. In this way, the friction between the arc-shaped support plate 8 and the pressure vessel is increased, and the stability of the support fixture for the pressure vessel is improved.

[0022] like Figure 1-Figure 4 As shown, the displacement assembly includes two fixed plates 6, and the two fixed plates 6 are fixedly connected to the top of the base plate 1. Threaded rods 9 are rotatably connected between the two fixed plates 6 and the two sides of the support seat 2. The outer side of the threaded rod 9 is threadedly connected to the movable plate 7. A cavity 11 is opened inside the support seat 2, and a rotating connecting rod 12 is rotatably connected between the inner walls of the cavity 11. Both ends of the rotating connecting rod 12 extend to the outside of the support seat 2 and are respectively fixedly connected to the two threaded rods 9. A driving bevel gear 13 is rotatably connected to the inside of the cavity 11, and a driven bevel gear 14 is fixedly connected to the outer side of the rotating connecting rod 12. The outer side of the driven bevel gear 14 meshes with the tooth edge of the driving bevel gear 13. A servo motor 10 is fixedly installed on the outer side of the support seat 2, and the output end of the servo motor 10 extends to the inside of the cavity 11 and is fixedly connected to the driving bevel gear 13.

[0023] The active bevel gear 13 is driven by the servo motor 10 to rotate inside the cavity 11. Since the active bevel gear 13 is meshed with the driven bevel gear 14, the active bevel gear 13 rotates and drives the rotating connecting rod 12 to rotate between the inner walls of the cavity 11, thereby driving the two threaded rods 9 to rotate on the outside of the support seat 2. Then, through the rotation of the threaded rods 9, the two movable plates 7 move on the top of the bottom plate 1 at the same time. This design makes it convenient to bring the two arc-shaped support plates 8 close to the pressure vessel at the same time, strengthen the support for the pressure vessel, and make the support of the pressure vessel by the support tooling more stable.

[0024] The utility model provides a supporting tool for manufacturing a pressure vessel, and the specific working principle is as follows: when using the supporting tool, firstly, the pressure vessel is placed inside the arc-shaped supporting groove 3, and then air is injected into the airbag 4 through two air pumps 5 to expand the airbag 4 and contact the outer side of the pressure vessel, and then the servo motor 10 is used to drive the active bevel gear 13 to rotate inside the cavity 11. Since the active bevel gear 13 is meshed with the driven bevel gear 14, the active bevel gear 13 rotates and drives the rotating connecting rod 12 to rotate between the inner walls of the cavity 11, thereby driving the two threaded rods 9 to rotate on the outer side of the support seat 2, and then through the rotation of the threaded rod 9, the two moving plates 7 are simultaneously moved on the top of the bottom plate 1, so that the arc-shaped support plate 8 in the side groove 15 contacts the outer side of the pressure vessel, and the rubber gasket 16 fits with the outer side of the pressure vessel.
