Description
Technical field
The present invention relates to a kind of longitudinal seam welding of barrel device, and in particular to a kind of automatic welding of truck air tank longitudinal joint
Connection device.
Background technology
At present, the welding production of cylinder longitudinal joint is typically carried out using cantilever structure welding machine.This welding machine mainly by support,
Cantilever beam, support shaft, key plate, centering body, padlock, welding gun walking mechanism, welding gun clamping and welding gun governor motion, electric-controlled
System part forms.Its course of work is broadly divided into four steps：It is to carry out tack welding to cylinder to connect first, by the cylinder after edge rolling
Preliminary pad is determined on positioning fixture；Second, feeding, by put it is fixed after cylinder be placed on the cantilever beam of welding machine, and with key plate
Cylinder is clamped, to ensure that longitudinal seam is parallel with welding gun walking mechanism, and welding gun is directed at weld seam, cylinder feeding uses when installing
Centering body positioning longitudinal joint position, finally locks cantilever beam with padlock mechanism, improves welding machine rigidity；Third, welding, the welding gun starting the arc
And advanced under the dragging of walking mechanism by certain speed and complete welding；It is finally blanking, after welding, opens cantilever beam
Padlock mechanism, cylinder is unloaded from cantilever beam, complete longitudinal seam welding of barrel.
The problem of following three aspects be present in this cantilever design welding machine：
First, weld defect easily occurs for weld seam.On the one hand, although defining position while welding using centering body when cylinder is installed,
But because centering body, welding gun walking mechanism all have certain interval, it is difficult to ensure that welding gun is constantly in Weld pipe mill, cause to weld
Road deviates, and produces weld defect, is showed when being welded using plasma or laser TAG particularly evident；On the other hand, the weldering of docking
Stitch both sides welding heat can not possibly it is completely the same, deformation be also impossible to it is identical, simultaneously because piano type clamp system clamping force has
Limit, insufficient clamping force with overcome due to caused by sweating heat workpiece deform, make butt weld both sides produce the height upper deviation, and this
Easily trigger weld defect, have especially when cylinder is using the larger material of this kind of linear expansion coefficient of stainless steel, during weld defect
Produce.
Second, postwelding barrel distortion is big, welding machine is without correction because welding heat triggers the mechanism of welding deformation, postwelding cylinder
Body section deformation is larger, influences follow-up end cap group to assembling and weld job, while product appearance quality is not high.
Third, production efficiency is relatively low, tack welding need to be carried out on positioning fixture before barrel soldering connects, welding conveyor front barrel assembling
And postwelding cylinder unloads under cantilever beam, all need to expend the time, and material is carried, and is wasted time and energy.
Chinese invention patent application（Application No.：201210322324.8 date of publication is：On 03 26th, 2014, title
For：Tunnel type cylinder longitudinal seam welding machine）It is automatic to disclose a kind of charging, centering, welding, cylinder longitudinal joint for discharging of integrating
Welder.The feeding mechanism of the device is made up of the roller of some groups of active rotations of distribution symmetrical above and below, by cylinder with
The frictional force drives cylinder reach between roller is fed, passes sequentially through feeding mechanism, welding mechanism and discharging mechanism.The welding fills
Although putting and solving the problems, such as above-mentioned cantilevered bonding machine low production efficiency, the feeding manner of the welder is actually using
During but easily occur feeding that not smooth, charging rate is uneven or treats the problem of welding line is larger, the cylinder that the device is welded
The problem of weldquality is unstable, qualification rate is low be present in longitudinal joint（Main cause is at following two aspects：First, it is rolled into the plate of cylinder
It is completely the same to expect that length is virtually impossible to, there will necessarily be error, that is, error is had by the diameter of weldering cylinder, when straight
When footpath is larger, resistance when cylinder passes through welding mechanism can easily occur feeding not freely, but when diameter is smaller, easily occur very greatly
The problem of weld gap to be welded is big, is difficult to ensure that welding quality；2nd, welding process is uneven to workpiece heat, will necessarily produce
During the larger material of raw this kind of linear expansion coefficient of welding deformation, especially soldering stainless steel, welding deformation becomes apparent, now cylinder
The resistance that body passes through in welding mechanism can unpredictably change, not smooth so as to can also induce charging）.The welding dress of the structure
Put that poor to cylinder plate length fault-tolerant ability, resistance change adaptability is not strong, is still easier to being fed caused by welding deformation
Weld defect is produced, meanwhile, the structure of the device is also complex, manufacture maintenance cost is higher.
The content of the invention
The purpose of the present invention is the defects of being directed to above-mentioned existing barrel soldering device and deficiency, there is provided a kind of structure letter
