In addition, shown in Fig. 2 and Fig. 5, in order to make the fixed effect of workpiece to be welded better, preferably, Work fixing device 12 also comprises bracket 122, this bracket 122 is arranged on the bottom of the workpiece laminating frame 111 of frame 11, for being fixed on this workpiece of supported underneath of the workpiece to be welded in frame 11.This bracket 122 comprises two horizon bar 122a that are parallel to each other and two vertical bar 122b that are parallel to each other, and the two ends of each vertical bar 122b are respectively arranged with through hole, and each horizon bar 122a is connected respectively with two vertical bar 122b by this through hole.The two ends of each horizon bar are provided with external screw thread, and the two ends of each horizon bar are respectively bolted with a locknut.Further preferably, vertically bar 122b can move along the length direction of horizon bar 122a, by locknut, bracket 122 is fixedly clamped on the correct position of workpiece laminating frame 111, wherein the corresponding square tube of workpiece laminating frame 111 is clamped between two horizon bar 122a.The preferred embodiment of the present invention is removably fixed in frame 11 bracket 122, and its position can be along the vertical direction up-down adjustment of frame 11, to adapt to the plate workpiece to be welded of different in width.
As described above, surface for the workpiece to be welded of fitting and the vertical direction of workpiece laminating frame 111 are the angle of 0 ° to 10 °, and bracket 122 is arranged on this workpiece laminating frame 111, therefore, " up-down adjustment " herein refers to that this angle can be 0 ° to 10 ° along the up-down adjustment in vertical direction with certain angle of the bearing of trend up and down of workpiece laminating frame 111.Particularly, when the wider width of plate workpiece to be welded, can make bracket 122 move along frame 11 downwards; And when the width of workpiece is narrower, can make bracket 122 be moved upward along frame 11, can support workpiece to be welded, thereby meet the demand of the workpiece of different in width.Adopt bracket 122 at workpiece supported underneath workpiece to be welded, can make workpiece more firmly be fixed in frame 11, thereby guarantee further fixing effect.
In practical operation, first can by one in workpiece to be welded with crane lifting to leaning to workpiece laminating frame 111, then according to the width of workpiece to be welded, bracket 122 is transferred to suitable position, even if it holds the following of workpiece, and by one group of workpiece tension part of below, workpiece is fixed; Then with crane, another in workpiece to be welded is lifted on to the top of the workpiece to be welded being fixed, makes limit to be welded (i.e. the top lower limb of workpiece and the top edge of the below workpiece) adjacency of two workpiece; Then use one group of workpiece tension part of top that the workpiece of top is fixed.Then the protection air lift of controlling welding tractor 221 and synchronizeing with it is synchronously moved along guide rail 21 for part 222; so that welding gun 221a under the control of source of welding current 221b along with the motion of welding tractor 221 to carrying out Plasma Welding in the limit to be welded of upper and lower two plate workpieces, make to protect air lift to provide protective gas for 222 pairs of welding positions of part simultaneously.
Also disclose according to another aspect of the present invention a kind of for splicing the automatic soldering method of plate workpiece.According to the automatic soldering method of the embodiment of the present invention, comprise the following steps:
The first step: place the first plate workpiece, make the first plate workpiece and vertical direction be the angle of 0 ° to 10 °, so that this first plate workpiece and other workpiece to be welded more easily overlap, and the edge horizontal direction to be welded of the first plate workpiece is extended, afterwards the first plate workpiece is fixed;
Second step: the second plate workpiece is lifted on to the first plate workpiece top with crane, make itself and the first plate workpiece overlap and be positioned at same plane with the first plate workpiece, the second plate workpiece is fixed, and make the limit to be welded of the second plate workpiece and the limit adjacency to be welded of the first plate workpiece, to carry out ensuing welding;
The 3rd step: carry out Plasma Welding along the limit to be welded of the first plate workpiece and the limit to be welded of the second plate workpiece, the back side at workpiece to be welded in the time of welding synchronously provides protection gas, to avoid workpiece oxidation to be welded, improves weldquality.
The present invention is illustrated by above-described embodiment, but should be understood that, above-described embodiment is the object for giving an example and illustrating just, but not is intended to the present invention to be limited in described scope of embodiments.In addition it will be appreciated by persons skilled in the art that the present invention is not limited to above-described embodiment, according to instruction of the present invention, can also make more kinds of variants and modifications, these variants and modifications all drop in the present invention's scope required for protection.Protection scope of the present invention is defined by the appended claims and equivalent scope thereof.
