It sets.
Background technique
In rail traffic, laser welding in stainless steel car body welding using more and more extensive, but due to laser welding
Device focus is smaller, keeps the clamping of workpiece height-limited；Secondly laser welding has compared with strict requirements workpiece welded gaps, therefore
It needs to provide enough pressure, makes gap in allowed limits, guarantee good welding quality；Again, the weldering of workpiece crossbeam
It is larger to connect deflection, to have enough pressure to overcome welding deformation, guarantees Product jointing shape.In actual welding, in order to guarantee
Welding quality need to usually guarantee that the gap of wallboard and workpiece crossbeam is less than 0.1mm, to guarantee weldment size, improve assembly precision
And efficiency, welding deformation is prevented, needs to be fixed welding workpiece crossbeam using compressing fixture.
Traditional pressing device is two end pressure block of crossbeam compression, because laser focal maximum height is generally less than 200mm,
It causes not can guarantee the requirement of welded gaps without space is put to good use in briquetting height, so that ideal compression effect much be not achieved.
In the welding process because middle part is without constraint is compressed, product itself welding deformation amount is larger, and each crossbeam is successively accumulated, and causes product
It is severely deformed, influence appearance；Meanwhile in order to reach compression effect as far as possible, it will usually it is interim using from two sides installation compression beam,
Increase the compaction measures such as briquetting, but weld seam is be easy to cause to be interrupted and need multiple repair welding, production efficiency substantially reduces.Traditional two
End pressure block compresses mode poor universality, and for same vehicle different units, (product unit length is different, but arc-shaped sections one
Cause), compressing fixture also can not be general.Therefore, it is very necessary for improving for traditional pressing device in laser welding.
