Abstract

The utility model provides an automatic welding device used for cylindrical weldments. The automatic welding device comprises a welding gun connected with a trolley operating rack, wherein one end of the welding gun is movably connected with the trolley operating rack; a welding gun rotation device is connected above a nozzle of the welding gun by a rack; and the welding gun is driven by the welding gun rotation device to rotate to a proper position. The automatic welding device has the advantages that structure is simple and operation is convenient; and when the automatic welding device is used for welding the cylindrical weldments, the position of the welding gun can be conveniently adjusted by the welding gun rotation device according to positions of longitudinal seams and circular seams, so that the welding operation efficiency of the automatic welding device is high, and the labor intensity of the operating personnel can be efficiently lowered.

Description

A kind of cylindrical weldment automatic soldering device
Technical field
The utility model relates to welding field, especially a kind of cylindrical weldment automatic soldering device.
Background technology
At present; in the existing gas shielded arc welding manipulator in market; when carrying out the welding of the cylindrical weldments such as pressure vessel, if existing longitudinal joint is arranged on the weldment, circumferential weld is arranged again; because welding gun can only be an angle position welding in the present welding machine; as: if the welding gun of welding longitudinal joint position is wanted girth weld, then need the position of travelling workpiece or move operation, this welding manner operates cumbersome; welding efficiency is low, and labour intensity is large.The existing weak point of prior art that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly for the existing deficiency of prior art, and provides a kind of easy to operate, the cylindrical weldment automatic soldering device that operating efficiency is high.
This programme is achieved by the following technical measures: this cylindrical weldment comprises the welding gun that links to each other with the dolly crosshead with automatic soldering device, one end of described welding gun and dolly crosshead are flexibly connected, and the nozzle top of welding gun is connected with the welding gun whirligig by support.
Above-mentioned welding gun whirligig comprises the left-right rotary rotating shaft, and the outside of left-right rotary rotating shaft is set with the sleeve with positioning knob, and the below of sleeve and left-right rotary rotating shaft is fixed with thrust bearing.During welding, drive welding gun by the left-right rotary rotating shaft and turn to correct position, and fixing by the positioning knob location, need not to move weldment or mobile welding machine, can satisfy the welding conversion of longitudinal joint and circumferential weld in the cylindrical weldment.
The angle of rotation of above-mentioned left-right rotary rotating shaft is 0 °~180 °, and the left-right rotary rotating shaft drives welding gun take its axle center as the center of circle, can rotate in 0 °~180 ° scopes, adjusts the position of welding gun, to adapt to different welding requirements.
Bearing pin is adopted in above-mentioned left-right rotary rotating shaft.
The nozzle top of above-mentioned welding gun also is fixedly connected with wig-wag, and when weld seam was wider, in the welding process, wig-wag can drive welding gun and swing, to satisfy welding requirements.
The nozzle top of above-mentioned welding gun also is fixedly connected with the cross adjuster, in the welding process, by the height of cross adjuster adjusting electric arc, to guarantee the stability of welding.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this cylindrical weldment is with in the automatic soldering device, one end of welding gun and dolly crosshead are flexibly connected, the nozzle top of welding gun is connected with the welding gun whirligig by support, drives welding gun by the welding gun whirligig and turns to correct position.This apparatus structure is simple, and is easy to operate, when carrying out cylindrical weldment welding, position according to longitudinal joint and circumferential weld, can adjust easily the position of welding gun by the welding gun whirligig, its weld job efficient is high, and has effectively reduced operating personnel's labour intensity.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation of welding gun whirligig among Fig. 1.
Among the figure, 1 is the cross adjuster, and 2 is wig-wag, and 3 is welding gun, and 4 is support, and 5 is the welding gun whirligig, and 6 is the dolly crosshead, and 7 is thrust bearing, and 8 is the left-right rotary rotating shaft, and 9 is positioning knob, and 10 is sleeve.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of cylindrical weldment automatic soldering device, as shown in the figure, it comprises the welding gun 3 that links to each other with dolly crosshead 6, one end of described welding gun 3 and dolly crosshead 6 are flexibly connected, the nozzle top of welding gun 3 is connected with welding gun whirligig 5 by support 4, and this welding gun whirligig 5 comprises left-right rotary rotating shaft 8, and the outside of left-right rotary rotating shaft 8 is set with the sleeve 10 with positioning knob 9, the below of sleeve 10 and left-right rotary rotating shaft 8 is fixed with thrust bearing 7, and thrust bearing 7 is fixedly connected with dolly crosshead 6.Wherein, the angle of rotation of left-right rotary rotating shaft 8 is 0 °~180 °, and the nozzle top of welding gun 3 also is fixedly connected with wig-wag 2 and cross adjuster 1.
When carrying out the welding of the cylindrical weldments such as pressure vessel, if have longitudinal joint and circumferential weld to need welding on the weldment, after the welding of having carried out longitudinal joint or circumferential weld, when turning to the welding of circumferential weld or longitudinal joint, unclamp positioning knob 9, rotate left-right rotary rotating shaft 8 to corresponding circumferential weld or longitudinal joint position, and screwed in place knob 9 gets final product, need not to move weldment or mobile welding machine.
When weld seam is wider, in the welding process, can drives welding gun 3 by wig-wag 2 and swing, to satisfy the weld job requirement.By the height of cross adjuster 1 adjusting electric arc, to guarantee the stability of welding.
Can pass through existing techniques in realizing without the technical characterictic of describing in the utility model, not repeat them here.
