In the present embodiment, it is not specifically limited for the structure of the first connecting seat 243 and the second connecting seat 245, this area
Technical staff can be configured according to being actually needed, as long as can realize that it supports the first compressor arm 244, the second compressor arm
246 function.Such as：The structure of second connecting seat 245 can be with the mounting support structure class in the first fixed seat 234
Seemingly.
The method for the group mounted welder welding workpiece for being used for bent section using the present embodiment is exemplified below：
To the long heavy section of arc, longitudinally prefabricated amount of deflection variable, profile length are L rice, apply numerical value and use using center as base
Standard, gradually successively decrease to both ends, each point of application is uniform according to L rice length, and the amount of deflection numerical value each put calculates according to car body amount of deflection
Obtained by method (deformation of the beam under uniform load).Such as：Uniform, peak F is carried out on the cambered surface section bar that length is L,
Both sides Rearrangments, F1~F5, f1~f5 are followed successively by respectively.
Specifically by taking 12m " L " type section curved section bars of double-deck bus body bottom as an example, according to the uniform load deformation gauge of beam
Calculate, it is 7mm that peak, which applies deflection, and with 1.5 meters for spacing, the uniform numerical value in both sides is respectively 6.5,5,2.7,0.
According to the result of calculation of the above method, load predeformation is applied to group mounted welder, then workpiece is installed, by workpiece
The heart and frock center alignment, i.e., apply maximum predeformation amount to group mounted welder to be alignd with workpiece centre, guarantee group mounted welder two
The anti-deformation that side applies symmetrically is applied on workpiece, using compressing according to this from the middle to both ends, so that external force is able to two
End release, ensure that workpiece and frock support meanss are completely closely connected.
In welding, bottom weld seam is fixed in spot welding first, is then welded top weld seam, is welded according to this using from middle part to both ends
The welding method connect, then bottoming welding arc top weld seam, bottoming are welded from middle part to both ends simultaneously using two welders, with
The predeformation direction of successively decreasing that curved section bars apply is consistent, ensures that the stress of this big cross section arc-shaped workpiece discharges to both ends.Top is beaten
After the completion of back welding connects, bottom weld seam is welded, welding method is identical with top weld seam welding sequence.
The welding method, welding can be completed on the premise of without using tipping arrangement, and ensure the morpheme size of workpiece not
Change.In addition, the welding method can also effectively avoid welding heat from concentrating input and disperse, and by being applied to workpiece
Add the reversible deformation that direction is consistent, welding stress is uniformly transmitted to both ends, discharge；Control unit welding deformation is realized, is reduced
The purpose of postwelding adjusting amount, improve product quality and part production efficiency.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, either which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
