Description

Circumferential weld CO in the cylindrical shell 2Gas shielded automatic welding machine
Technical field
The utility model belongs to CO 2Circumferential weld CO in the improvement of gas shielded welding machine, particularly cylindrical shell 2Gas shielded automatic welding machine.
Background technology
At present, in the known cylindrical shell circular-seam welding method more advanced be to adopt cantilevered CO 2Gas shield welding manipulator welds circumferential weld in the cylindrical shell.The cantilever collapsing length is limited, is generally about 10 meters, puts in that effectively active length is shorter in the cylindrical shell, and is powerless for the overlength cylindrical shell; Meter font that is provided with some large diameter cylindrical shell supports and more can't use; And can only weld an interior circumferential weld, use underaction convenient.
Summary of the invention
The purpose of this utility model is to provide circumferential weld CO in a kind of cylindrical shell 2Gas shielded automatic welding machine, it is simple and compact for structure, can weld the circumferential weld in the cylindrical shell quickly and easily, and the cylindrical shell welding that is fit to all kinds of diameters is used.
The purpose of this utility model is achieved in that circumferential weld CO in a kind of cylindrical shell 2Gas shielded automatic welding machine; comprise that one is equipped with the dolly and the workbench of road wheel; be equipped with on the dolly by wire-feed motor; welding pendulum wire device; the weld assembly that the recirculated water cooling welding gun is formed; weld assembly and protection gas bottle; the source of welding current and cyclic water tank link to each other; two groups of adjustable speed swing rollers are being set on workbench at interval; cylindrical shell to be welded is placed horizontally on the swing roller; cylindrical shell is by the swing roller driven rotary; a circular orbit along cylindrical shell internal perisporium layout is being placed on circumferential weld next door in cylindrical shell; said road wheel is the track travel wheel; dolly moves along circular orbit by road wheel, and circumferential weld is welded.
During the utility model work, drive the cylindrical shell rotation by the swing roller on the workbench, simultaneously, the dolly that weld assembly is housed moves along the circular orbit in the cylindrical shell, and butt welded seam welds.Operation is not subjected to the restriction of caliber and pipe range fully, can weld the circumferential weld in the cylindrical shell quickly and easily, and the cylindrical shell welding that is fit to all kinds of diameters is used.This machine structure is simply compact, and the circumferential weld in the cylindrical shell is welded, and is easy to operate.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of the utility model track;
Fig. 3 is the cross sectional representation of the utility model track.
The specific embodiment
Circumferential weld CO in a kind of cylindrical shell 2Gas shielded automatic welding machine; as Fig. 1, Fig. 2, shown in Figure 3; comprise that one is equipped with the dolly 1 and the workbench of road wheel; the weld assembly of being made up of wire-feed motor 2, welding pendulum wire device 3, recirculated water cooling welding gun 4 is housed on the dolly 1, and weld assembly links to each other with protection gas bottle 9,10, the source of welding current 12 and cyclic water tank 13.Welding pendulum wire device 3 can be controlled welding gun 4 and swing to reach the specific (special) requirements in the automatic welding process with specific preset parameter.Adopt advanced single-chip microcomputer to control, the LED that is equipped with high brightness shows and long-life button that touches that all input and output ports have all adopted the photoelectricity isolation, can carry out work under the environment provided condition for a long time incessantly.At interval two groups of adjustable speed swing rollers 8 are being set on workbench, cylindrical shell 7 to be welded is placed horizontally on the swing roller 8, and cylindrical shell 7 is by swing roller 8 driven rotary.A circular orbit 6 along cylindrical shell 7 internal perisporiums layout is being placed on circumferential weld next door in cylindrical shell 7, and said road wheel is the track travel wheel, and dolly 1 moves along circular orbit 6 by road wheel, and circumferential weld is welded.
As Fig. 2, shown in Figure 3, said circular orbit 6 constitutes for being joined end to end by some joint rubber strips, the middle part inner peripheral of rubber strip protrudes the formation cross section to the cylindrical shell center and is trapezoidal track body 16, said road wheel outer rim middle part is being provided with an annular groove, annular groove matches with said track body 16, through hole 14 is being set respectively on the rubber strip belt body 15 of track body 16 both sides at interval, one magnet piece that is adsorbed on the cylinder inboard wall is being set, in order to circular orbit 6 is positioned in each through hole 14 respectively.
Said circular orbit 6 can also be made of the chain rail.
