The invention relates to the technological equipment of the welding industry, in particular to devices for assembling and welding thin-walled spherical products.

The purpose of the invention is to simplify the design.

FIG. 1 shows a manipulator for manufacturing spherical products, general view; in fig. 2 — node I in FIG. one; in fig. 3 is a view A of FIG. 2

Manipulator for the manufacture of spherical products contains the rack 1, placed on the foundation (not shown) around the perimeter of the product 2 on the wedge x 3 and connected through the movable cantilevers 4 to the support ring 5, to which the spherical capacity 6, reinforced by annular and meridian, is attached to the bottom reinforcement tapes 7.

In the spherical tank 6, radially mounted and diametrically opposed supply lines 8 are mounted on which bubblers 9 are fixed. Each supply line is connected by means of a sealing element 10, pipes 11, flexible inserts 12 and valves 13 with a source of compressed air, for example, a compressor 14.

The spherical container 6 is connected by the injection pipe 15 to a liquid supply source, for example a pump 16 supplying liquid from the accumulator 17, and a drain pipe 18. The welding tractor is marked with the position 19. j The manipulator is operated as follows: ipasoM.

: On the foundation of the product 2, they are mounted racks 1 and deflected by an angle of 3-5 ° from the vertical using wedges 3 for the convenience of mounting the product 2. At the required height, mobile consoles Li 4 and A support ring 5 is freely mounted on them, on which the product 2 is welded from separate elements with manual arc welding of the inner root shvi to form hermetic joints. A flexible spherical container 6, reinforced by annular and meridian reinforcement tapes 7, is then attached to the support ring 5. Water is fed into the spherical container 6 through the discharge pipe 15 by means of a pump 16 until the product 2 emerges and is allowed to rotate freely. On top of product 2, a welding tractor 19 is installed and automatic welding of the external shvov is carried out.

To do this, using an air compressor 14, through a control valve 13 and a pressure pipe 11, compressed air is supplied to one of the supply pipes 8, thereby reducing the specific gravity of the liquid in one of the halves of the spherical container 6 and jointly rotating the product 2.

The welding tractor 19 performs automatic welding.

If it is necessary to stop the rotation, compressed air is supplied in a similar way to another supply line.

5 When the direction of rotation needs to be changed meridially, the pipelines 8 with bubblers 9 are rotated in the sealing element 10 by means of flexible inserts 12.

After the end of the welding of the product 2, the liquid from the spherical container 6 is discharged through conduit 18 to accumulator 17, all feeding systems are disconnected. The spherical capacitance 6 is removed from the support ring 5. Then it is removed from one of the uprights

5, the arm 4, the wedge 3 is taken out, after which the support ring 5 is removed for subsequent transportation.

The use of the proposed manipulator device makes it possible to drastically reduce the cost of the manipulator by eliminating an expensive rotator without increasing the labor intensity of welding works and reducing the quality of welding joints.

In addition, the pressure on the flexible thin-walled shell of the tank is reduced, which is important for its strength.
