Technical Field

[0001] The utility model relates to the technical field of pressure vessel production, in particular to a positioning tool for pressure vessel production. Background Art

[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. Pressure vessels are widely used in many departments such as industry, civil industry, military industry, and many fields of scientific research, and they play an important role. Pressure vessels are generally composed of a cylinder and heads at both ends. The cylinder is made of steel plates that are curled and longitudinally welded. The cylinder and the head are fixed by ring welding, so positioning tooling is required during production.

[0003] At present, the positioning fixtures used by most factories are simply used to position two pressure vessels. The pressure vessels are round, and the pressure vessels need to be rotated to fully weld them. However, the pressure vessels themselves are heavy, and it is inconvenient to rotate the pressure vessels, which will affect the efficiency of pressure vessel production. Utility Model Content

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 positioning tool for pressure vessel production includes a positioning support frame 1, both sides of the positioning support frame 1 are fixedly connected to a protection box 3, a driving motor 2 5 is fixedly installed in the middle of one side of the protection box 3, the output end of the driving motor 2 5 is fixedly connected to a rotating shaft 17, one end of the rotating shaft 17 is fixedly connected to a rotating frame 6, the outer side wall of the rotating shaft 17 is slidably connected to a sleeve rod 18, the other side of the protection box 3 is fixedly installed with a driving motor 1 4, the output end of the driving motor 1 4 is fixedly connected to a worm 15, the outer side wall of the worm 15 is meshed with a worm wheel 16, one side of the worm wheel 16 is fixedly connected to a gear 19, the outer side wall of the gear 19 and the sleeve rod 18 are slidably connected. One side of the outer wall of the sleeve rod 18 is meshed, and the other side of the outer wall of the sleeve rod 18 is meshed with a gear 20. The inner wall of the gear 20 is fixedly connected with a threaded rod 21. The outer wall of the threaded rod 21 is threadedly connected to two clamping blocks 22. Turn on the drive motor 14, the worm 15 and the worm wheel 16 are meshed to drive the gear 19 to rotate, so that the sleeve rod 18 slides on the rotating shaft 17, so that the threaded rod 21 drives the two clamping blocks 22 to approach each other, and the produced pressure vessel is fixed for welding. At the same time, turn on the drive motor 25 to rotate the rotating frame 6, driving the pressure vessel on the clamping block 22 to rotate together, avoiding the inconvenience of rotating the pressure vessel and improving the efficiency of pressure vessel production.

[0021] like Figure 1 As shown, the four corners of the lower end of the positioning support frame 1 are fixedly connected with support feet 2, and the support feet 2 are used to support the entire device.

[0022] like Figure 1 and Figure 2As shown, a damper 13 is rotatably connected to the middle part of the upper end of the positioning support frame 1, one end of the damper 13 is fixedly connected to a buffer frame 10, the upper end of the buffer frame 10 is fixedly connected to a damper 2 14, one end of the damper 2 14 is fixedly connected to a protective platform 7. When the pressure vessel is placed on the clamping block 22, the gravity of the pressure vessel will press the protective platform 7 downward, and the damper 2 14 and the damper 1 13 will buffer the gravity, thereby avoiding the gravity of the pressure vessel being entirely supported by the two clamping blocks 22, thereby improving the service life of the equipment.

[0023] like Figure 1 and Figure 2 As shown, a plurality of rollers 8 are fixedly connected to the upper end of the protection platform 7. The rollers 8 are used to facilitate the rotation of the pressure vessel on the protection platform 7 and prevent the surface of the pressure vessel from being scratched during rotation.

[0025] like Figure 1 - Figure 3 As shown, a slide groove 23 is provided on one side of the rotating frame 6, and the inner wall of the slide groove 23 is slidably connected to the outer wall of the clamping block 22.

[0026] The utility model provides a positioning tool for pressure vessel production, and the specific working principle is as follows:

[0027] When producing a pressure vessel, first place the steel plate of the pressure vessel on the roller 8, the gravity of the pressure vessel will press the protective platform 7 downward, the sliding block 11 will move in the buffer frame 10, and the damper 2 14 and the damper 1 13 will buffer the gravity, then turn on the drive motor 1 4, the worm 15 and the worm wheel 16 will mesh to drive the gear 19 to rotate, so that the sleeve rod 18 slides on the rotating shaft 17, so that the threaded rod 21 drives the two clamping blocks 22 to approach each other, and the produced pressure vessel is fixed for welding. At the same time, turn on the drive motor 2 5 to rotate the rotating frame 6, drive the pressure vessel on the clamping block 22 to rotate together, and the roller 8 on the protective platform 7 also rotates with the pressure vessel. After the production is completed, turn on the drive motor 1 4 to rotate the worm 15 in the opposite direction, so that the two clamping blocks 22 are away from each other, thereby releasing the restriction of the pressure vessel and removing the pressure vessel.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
