Description
Technical field
The utility model relates to bridge welding auxiliary mould field more particularly to a kind of bridge U-rib welding anti-distortion devices.
Background technique
The welding of U rib on general bridge uses Karma formula to carry out what limit welding was generated to reduce U rib in welding process
Deformation is easy to cause the interruption of the process of welding in process of production since the structure of Karma is across on U rib, it is not smooth and
It uses the structure of Karma formula to control deformation for artificial limitation but is easy to produce internal stress in the welding process；Therefore it needs to use
A kind of next preset anti-deformation of welding tooling, not only can control deformation quantity, but also can be reduced the generation of internal stress in this way, reduces later period fire
The time of flame correction, improve production efficiency.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of bridge U-rib welding anti-distortion devices, are able to solve one
As bridge U-rib welding use Karma formula structure, lead to weld deformation quantity control trouble, internal stress generates huge and later period and needs
Take a long time the problem of carrying out flame straightening.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of bridge U-rib welding anti-distortion device,
Its innovative point is: including support baseboard, Guide rollers group, portal frame, welding tractor and positioning moulding bed；
The support baseboard is horizontally disposed on the ground by clamping screw, and the upper surface of support baseboard is along support baseboard
Extending direction be arranged in parallel with several lower articulated slabs；The Guide rollers group is separately positioned on the two sides of support baseboard, gantry
The bottom end of frame is connected in Guide rollers group and is provided with sliding rail, Guide rollers group on support baseboard, the crossbeam of portal frame
Pulley driving portal frame along guide rail extending direction move back and forth；
The welding tractor is cooperated by the sliding rail on sliding block and portal frame, and welding tractor is horizontally set on gantry by one
Reciprocating motion on the gantry is realized in driving cylinder driving on frame crossbeam；
The positioning moulding bed is located at the top of support baseboard, is provided on the lower end surface for positioning moulding bed and support baseboard
The upper articulated slab of upper and lower articulated slab cooperation；Pass through on upper articulated slab on the positioning moulding bed and the lower articulated slab on support baseboard
Single-revolution axis is connected, and the positioning moulding bed can be rotated around rotating shaft realizes that the tilt angle of positioning moulding bed is adjusted；The positioning
The edge of moulding bed is provided with several positioning fixtures along the extending direction of positioning moulding bed.
Further, several angles positioning pore structures are provided on the bottom face of the positioning moulding bed, on the support baseboard
It is provided with and realizes that the angle of positioning moulding bed is fixed with the lip block of angle positioning pore structure cooperation.
Utility model has the advantages that
1) in the utility model, the jig structure being arranged using tiltable, the tilt angle of control positioning moulding bed, thus real
Existing U rib is in heeling condition before welding, so that the center of gravity of U rib shifts, U rib weight is relied in the welding process of U rib
The variation of the heart reduces internal stress and deformation quantity that welding generates, to realize the time for reducing subsequent flame straightening, improves life
Produce efficiency.
