Description

A kind of light-wall pipe welding aligns locator

Technical field

The utility model relates to a kind of light-wall pipe welding and aligns locator, is used to control parallel the aligning of sheet-metal duct welding process two tube walls, improves welding quality, to meet code requirement.

Background technology

Light-wall pipe is because self intensity is low, yielding, and aligning of welding process is difficult, and the pipe of the big medium caliber that particularly wall is thin is because it is when focusing on horizontal positioned; Just be out of shape, align loaded down with trivial detailsly at the construction field (site), efficient is very low, and existing pipeline is used for the installation of heavy wall pipe more to mouthpart; Bulky, can not use on sheet-metal duct, be prone to make the sheet-metal duct distortion, and single can't moving and carry; Also impracticable, use the present invention to align locator, can quick and precisely align, save a lot of loaded down with trivial details programs; Make the tube that aligns change of light-wall pipe welding process single efficient, eliminated craft and aligned the various artificial factor of process, simple in structure, and portable.

The utility model content

The purpose of the utility model is to overcome light-wall pipe welding process two tube walls to align loaded down with trivial detailsly, and efficient is low, aligns of poor qualityly, has invented for this reason and has aligned locator; To save time, the power that lightens one's labor improves welding quality; For realizing above-mentioned purpose, the light-wall pipe welding of the utility model aligns locator, bearing, operation handlebar, T type devices such as positive is made up of; It is characterized in that: pacify depression bar on the eccentric wheel, eccentric wheel connects connecting rod, and connecting rod passes support and is connected with connecting cylinder by pin rod; Or action bars with the axle be connected on the bearing, an end of action bars is connected with connecting cylinder by pin rod; Or revolved support by the screw rod of band spanner, and be connected with connecting cylinder with pin rod, finally by connecting cylinder connection motion bar, motion bar is connected positive with the T type with connecting pin.

Said T type is that the flaky material of the welded tube road weld width by being less than or equal to is processed to the bottom transverse position of positive; Its vertical middle part is be less than or equal to institute's welded tube road weld width shaft-like, and its other end connects motion bar, said structure can be easily the T type to injecting in the pipe the weld seam of positive between two pipes; Position, intermediate portion shaft-like can be revolved to turn 90 degrees in weld seam and held tube wall; Be that two mouths of pipe are concordant, simple to operate, laborsaving fast; The mouth of pipe aligns accurately, has improved efficiency of construction and welding quality greatly.

Said T type is that the flaky material of the welded tube road weld width by being less than or equal to is processed to the bottom transverse position of positive; Its vertical middle part is be less than or equal to institute's welded tube road weld width shaft-like; Its other end connects motion bar; The T type is the technical characterictic of the utility model to positive, and the cross sectional shape at the horizontal position of its hard straight middle part and bottom can be arbitrarily, but can there be bigger loading end at the bottom transverse position when processing sheet.

Said T type is that cylinder 19 materials of the welded tube road weld width by being less than or equal to are processed to the bottom transverse position of positive 2.

Eccentric radially centre is a groove, and connecting rod is positioned in the groove.

Pacifying movable leg on the supporting leg of frame bottom, can be that support better contacts with the outer wall of different tube diameters is well identical like this, increases contact-making surface, the distortion of pipeline difficult local.
