Description
Technical field
The utility model relates to welding field, particularly a kind of welding work pieces erecting device.
Background technology
In welding field, metal solder is very general.Welding procedure is through development for many years, also basic development maturation.Such as compressor liquid storage device, air conditioner muffler, gas-liquid separator for central air-conditioning, the product such as gs-oil separator, fire extinguisher, air accumulator for central air-conditioning, its housing is all by being welded.Plugging into of for example some tubing again, comprises plugging into of metal pipe material of the same race or plugging into of dissimilar metal, all can realize by welding.
Taking compressor liquid storage device as example, its housing generally adopts ferrous material to make, generally there are two kinds of structures: (1) housing divides the first half and Lower Half two parts, wherein the internal diameter of the welding ends of a part is greater than the external diameter of another part, two parts socket, between cover junction, have spelter solder, then entirety was carried out stove weldering.(2) housing comprises the cylindrical shell of a hollow and is combined in respectively upper end cover and the bottom end cover at cylindrical shell two ends, and welding ends corresponding to three parts is also socket, between cover junction, has spelter solder, and then entirety was carried out stove weldering.But the job costs of this welding manner are high, complex procedures, efficiency are very low, and weld strength is general.
For addressing the above problem, Chinese patent application 201210589308.5, a kind of compressor and manufacture method thereof and application are disclosed, wherein reservoir housing comprises the cylindrical shell of a hollow and is combined in respectively upper end cover and the bottom end cover at cylindrical shell two ends, between each part, dock, craft port is welded by flash welding.
But, adopt above-mentioned technique to occur again other problems: flash welding need to clamp housing each several part and implement upset force and reach certain upset speed, easily make surface occur clamping wound; If housing adopts above-mentioned (2) to plant structure, due to the restriction of flash welding technique, when welding, component, by having separation, close action, cannot realize three parts and weld simultaneously, need to weld at twice; Due to each several part separating for several times, contact, centering, while making to weld, centering is poor; Extrude to both sides because upset force makes the iron of each several part weld melting, make the surfaces externally and internally of housing weld all be formed with protruding foreign matter; Bonding power requires larger, and therefore equipment investment is large; The more difficult control of weld strength, for example, while welding, each several part approaches-separates, and heat is unstable, and welding quality is also unstable, and thermal stress is large, and impulsive force is large, easily causes lattice fracture, produces fire check.
In Chinese patent application 201310484818.0, disclose a kind of housing and manufacture method thereof, by argon arc welding, plasma weldering, the weldering of accurate ion, Laser Welding etc., housing has been welded, its welding quality is improved, and production efficiency improves.When welding, because weld seam is annular, therefore need roll-shell, make circular weld slowly pass through the position of torch neck by circumferencial direction, when welding, need exactitude position, complete welding.
But, be difficult to make their the smooth of the edges to be welded smooth owing to manufacturing when cylindrical shell, upper end cover or bottom end cover, edge roughness to be welded be parallel in the direction of axis, often have concavo-convex.And edge to be welded is also difficult to ensure to be a positive circle, therefore makes also often to have deviation (roundness tolerance) on perpendicular to axis direction.In traditional bonding machine, for the welding of circular weld, normally first the one or both ends of cylindrical shell are coaxially fixed in drive shaft, driven by motor drive shaft is rotated, thereby makes cylindrical shell synchronize and rotate with drive shaft.Because the size of cylindrical shell own exists tolerance, be difficult to ensure coaxial installation and be installed in drive shaft to exist, easily there is eccentric tolerance, through the enlarge-effect of accumulation stack, tolerance even can expand to ± and more than 3mm.There is hitting rifle (welding gun and workpiece to be welded touching) and disconnected phenomenon of welding in above reason, also can cause that the problem of welding quality cannot be aimed at and then affect to welding gun due to edge offset to be welded while being easy to cause welding.
