As described above, workpiece laminating frame 111 is in 0 ° to 10 ° for the surface for workpiece to be welded of fitting and vertical direction
Angle, and bracket 122 is arranged on workpiece laminating frame 111, and therefore, " up and down adjust " herein refers to fit along workpiece
The regulation up and down in vertical direction with certain angle of the bearing of trend up and down of frame 111, the angle can be 0 ° to 10 °.Specifically
Ground, when the wider width of plate workpiece to be welded, can be such that bracket 122 is moved downwards along frame 11；And when workpiece
During narrower width, bracket 122 can be made to be moved upward along frame 11, so that workpiece to be welded can be supported, so as to meet not
With the demand of the workpiece of width.Using bracket 122 in workpiece supported underneath workpiece to be welded, workpiece can be made more securely to fix
In frame 11, so as to further ensure that fixed effect.
Practice operation in, first can by one in workpiece to be welded with crane lifting to lean to workpiece laminating frame 111,
Then bracket 122 is transferred to appropriate position according to the width of workpiece to be welded, though it holds the following of workpiece, and under
One group of workpiece tension part of side fixes workpiece；Then another in workpiece to be welded is lifted on by fixed with crane
The top of workpiece to be welded, makes the side to be welded of two workpiece（The lower edge and the top edge of underlying workpiece of workpiece above i.e.）
It is adjacent；Then one group of workpiece tension part above use fixes the workpiece of top.Then control welds car 221 and synchronous
Protection air lift piece supplying 222 it is synchronous moved along guide rail 21 so that welding gun 221a under source of welding current 221b control with welding
The motion of car 221 and Plasma Welding is carried out to the side to be welded of two plate workpieces up and down, while making protection air lift piece supplying
222 pairs of welding positions provide protective gas.
A kind of automatic soldering method for being used to splice plate workpiece is also disclosed according to another aspect of the present invention.According to
The automatic soldering method of the embodiment of the present invention comprises the following steps：
The first step：The first plate workpiece is placed, makes the first plate workpiece and the angle that vertical direction is in 0 ° to 10 °, so that
Obtain first plate workpiece and be easier overlap joint with other workpiece to be welded, and make the edge to be welded of the first plate workpiece
Horizontal direction extends, and afterwards fixes the first plate workpiece；
Second step：The second plate workpiece is lifted on above the first plate workpiece with crane, makes itself and the first plate workpiece
Overlap joint and in being generally aligned in the same plane with the first plate workpiece, the second plate workpiece is fixed, and cause treating for the second plate workpiece
Welding is abutted in be welded with the first plate workpiece, to carry out ensuing welding；
3rd step：Along the first plate workpiece it is to be welded carried out in be welded with the second plate workpiece etc. from
Son welding, protection gas is simultaneously provided while welding at the back side of workpiece to be welded, to avoid workpiece to be welded from aoxidizing, improves weldering
Stitch quality.
The present invention is illustrated by above-described embodiment, but it is to be understood that, above-described embodiment is only intended to
Citing and the purpose of explanation, and be not intended to limit the invention in described scope of embodiments.In addition people in the art
Member according to the teachings of the present invention it is understood that the invention is not limited in above-described embodiment, can also make more kinds of
Variants and modifications, these variants and modifications are all fallen within scope of the present invention.Protection scope of the present invention by
The appended claims and its equivalent scope are defined.
