Problems solved by technology

[0002] When the heavy-duty circular workpiece is assembled and welded, because the weight and volume of its various components are very large, especially for pipe fittings with thicker pipe walls, it is very inconvenient to move and adjust, and it is difficult to assemble
Moreover, for workpieces with very high dimensional accuracy requirements, it is difficult to ensure the coaxiality after welding
[0003] If the traditional method of assembly and welding with positioner and roller frame is used, the left and right positions and heights of the workpiece cannot be adjusted during the assembly process, and the production efficiency is low. Even if it can be welded and formed, the coaxiality of the product is low , low quality pass rate
Moreover, the workpiece is too heavy, and it is inconvenient to move and adjust during the assembly welding process. It is difficult to adjust the coaxiality of each workpiece for assembly welding at any time, and the production controllability is poor.

Embodiment 1

[0067] Example 1, such as figure 1 , figure 2 , image 3 As shown, a pairing device includes a base 1, and two sets of support bases 2 are fixedly connected to the middle of the base 1. The two sets of support bases 2 are provided with a support platform 7 for supporting a workpiece 14, and the support bases 2 are used to support The part with the largest weight or volume in the workpiece is generally an intermediate pipe.

[0068] The support platform 7 is a support beam 3 or a support plate. When the support platform 7 is a support beam 3, the number of support beams 3 is at least two.

[0069] The upper end faces of the supporting beam 3 and the bottom of the workpiece 14 are flush with each other and maintain the same flatness.

[0070] One side of the upper end surface of the support beam 3 is provided with at least two first fixed plates, and the other side of the upper end surface of the support beam 3 is provided with at least two first fixed adjustment plates 5, ...

Abstract

The invention discloses an assembly device and a welding method using the same. The assembly device comprises a base, the base is provided with a supporting base, the supporting base is provided with a supporting platform used for supporting work-pieces, and a moving base used for supporting the work-pieces is arranged at the position, close to the end of the supporting base, of the base. According to the technical scheme, the size requirement for high accuracy between two assembled pipes and between flanges and pipes can be met, and assembly welding of lots of pipes of large and heavy work-pieces and assembly welding of the flanges and the pipes of the large and heavy work-pieces can be achieved at the same time; the assembly welding efficiency is high; controllable fine adjustment of distance between the large and heavy work-pieces can be achieved, the labor intensity of workers is low, adjustment is convenient, and the coaxiality can be well guaranteed; assembly welding of the work-pieces of the same specification can be achieved fast and efficiently.

Description

technical field [0001] The invention relates to the field of welding, in particular to a pairing device for butt welding of heavy-duty cylinders and cylinders, cylinders and flanges, and a welding method using the pairing device. Background technique [0002] When the heavy-duty circular workpiece is assembled and welded, because the weight and volume of its various components are very large, especially for pipe fittings with thicker pipe walls, it is very inconvenient to move and adjust, and it is difficult to assemble. Moreover, for workpieces with very high dimensional accuracy requirements, it is difficult to ensure the coaxiality after welding. [0003] If the traditional method of assembly and welding with positioner and roller frame is used, the left and right positions and heights of the workpiece cannot be adjusted during the assembly process, and the production efficiency is low. Even if it can be welded and formed, the coaxiality of the product is low , The quali...
