It is the inexorable trend of welding mechanism process industry modernization development with automation.
Track is a component indispensable in automatic welding application, and existing market is main in the application of small pipeline automatic welding
With the track that is made into of material using rigidity, as aluminium alloy is made into ontology, then the rack gear of many segments is mixed.
For pipeline itself, in order to improve its service life, corresponding erosion resistant coating may be coated in its outer surface.Pipeline
Anti-corrosion（corrosion prevention of pipes）Refer to chemistry, the electricity to slow down or preventing pipeline in inside and outside medium
The measure for being etched and going bad under chemical action or by the metabolic activity of microorganism.
However when outer diameter tube has error（It is bigger than normal）Or pipe surface, when having erosion resistant coating, this rigidity track can not just fit
Answer the welding demand at scene.
Application No. is the patents of invention of CN201410382471.3 to disclose a kind of elastic track formula pipeline outer wall automatic welding
Connection mechanism, including welding tractor circular motion module, welding gun move radially module, welding gun axial movement module and torch swinging mould
Block；Welding tractor circular motion module includes elastic track (1), servo drive motor (12), servo drive motor (12) connection
Driving gear (13), driving gear (13) are meshed with driven gear (32), circumferential on driven gear (32) and elastic track (1)
The gear ring of setting matches, and passes through liner (2) support between elastic track (1) and pipeline to be welded.And its preferred embodiment is public
Having opened the liner (2) is height-adjustable piston type extrusome.
Although this kind of mode can solve the problems, such as that pipe surface has erosion resistant coating to a certain extent, if necessary to right
When gasket height carries out height adjustment, certainly will exist and need simultaneously be adjusted all liners, since the more adjustment of quantity is numb
It is tired, and need to adjust all liners to identical height and just be able to achieve, using effect is very inconvenient.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of walking rails for small pipeline automatic welding
