Abstract
The utility model is specifically a kind of pairing device of posted sides pipeline groove；It is characterized in that：Including pipeline is placed on workbench；Pipeline is fixed respectively with locating rack；Gap adjustment ruler is inserted into the gap between two segment pipes, adjusts two segment pipes, makes gap adjustment ruler while is bonded two segment pipes；Gap locating piece is inserted into the gap location of two segment pipes；Gap locating piece is distinguished into spot welding, after the completion of spot welding, mobile group carries out complete solder to the opposite side of good pipeline to workbench；Gap locating piece is removed, pipeline is entered welding sequence, point weld clearance locating piece is removed using abrasive machine polishing after the completion of bottoming welding or segmentation bottoming welding.This group is to method using gap locating piece come the gap between accurate control pipeline, meanwhile the gap locating piece can remove, therefore pipeline is not caused to damage, therefore for this method is compared to traditional pipe string method, have the advantages that group is fast to speed, group is good to effect.
Description
Technical field
Pipeline engineering field is the utility model is related to, is specifically a kind of pairing device of posted sides pipeline groove.
Background technology
Pipe string is a step important in pipeline welding control, and the control of groove gap is a difficulty of pipe string
Point, especially for pressure pipeline, the quality of groove gap adjustment directly influences the welding quality of pipeline, under normal circumstances pipeline
Welding uses single face welding and double face shaping, so generally using argon tungsten-arc welding in pipeline welding, such a welding method is most favourable
In the internal soundness for ensureing pipeline welding.But when posted sides pipeline welds, since welding penetration is big, often in welding process
In with the input of heat produce welding deformation, seriously affect pipeline welding quality, it is therefore necessary to strictly to control groove
Gap.The method of adjustment of general groove gap has two kinds, and one kind is fixed by spot welding gusset, but can injure mother metal；Separately
One kind is direct spot welding after assembling, but is unfavorable for controlling the size in gap, so as to influence welding quality.
Utility model content
The purpose of this utility model is that, there is provided one kind will not only injure mother metal, meanwhile, improve welding quality control weldering
The group of deformation is connect to method.
In order to achieve the above object, the utility model is realized in this way：
A kind of pairing device of posted sides pipeline groove, including workbench, pipeline location frame, gap adjustment ruler, gap are fixed
Position block；The section of the gap adjustment ruler is in inverted " V " font, it has a pair and is arranged on workbench；Gap positions
Block is arranged between two pipelines, and the two sides of the gap locating piece are inclined, and the angle of its inclined plane is with treating group to pipe
The inclined plane angle of road end face is identical, i.e., when two segment pipe groups are to completing, gap locating piece both sides are complete with pipeline end face
Fitting.
This pairing device using gap locating piece come the gap between accurate control pipeline, meanwhile, which is
It can remove, therefore pipeline not caused to damage, therefore for this method is compared to traditional pipe string method, there is group
The advantages of, group fast to speed is good to effect.
Brief description of the drawings
Fig. 1 is that this group adjusts schematic diagram to the tube groove gap of method.
Fig. 2 is the sectional view along A-A in Fig. 1.
Fig. 3 is partial enlarged view at the B in Fig. 1.
Embodiment
The utility model is further illustrated below by way of specific embodiment.
As shown in Fig. 1 ~ Fig. 3, a kind of group of posted sides pipeline groove to method, including workbench 1, pipeline location frame 3,
Gap adjustment ruler 4, gap locating piece 7, described group includes method
Step 1, two segment pipes 5,6 that needs are docked are placed on workbench 1；
Step 2, with pipeline location frame 3 fix workbench both sides by two segment pipes respectively；
Step 3, be inserted into gap adjustment ruler 4 in the gap between two segment pipes 5,6, and gap adjustment ruler 5 is fitted in
At any one segment pipe port；
Step 4, two segment pipes 5,6 of adjustment, make gap adjustment ruler 4 while are bonded two segment pipes；
Step 5, the gap location insertion gap locating piece 7 in two segment pipes 5,6 described in step 4；
Step 6, by gap locating piece 7, point is welded at 0 °, 90 °, 270 ° of the groove circular arc of two segment pipes 5,6 respectively,
Pipeline 5,6, overturn gap locating piece 7 behind 180 ° of sides on 180 ° of directions of spot welding, after the completion of spot welding, moved by step 7
Dynamic group carries out complete solder to the opposite side of good pipeline to workbench 1；
Step 6, remove gap locating piece 7, pipeline 5,6 is entered welding sequence, and bottoming welding or segmentation bottoming have been welded
Point weld clearance locating piece is removed using abrasive machine polishing into rear.
The group of the posted sides pipeline groove is in method, the section of gap adjustment ruler 4 is in inverted " V " font.
For the group of the posted sides pipeline groove to method, the two sides of gap locating piece 7 are inclined, the angles of its inclined plane
Spend with treating that group is identical to the inclined plane angle of pipeline 5,6 end faces, i.e., when two segment pipe groups to complete when, gap locating piece both sides with
Pipeline end face is bonded completely.
This group to method using gap locating piece come the gap between accurate control pipeline, meanwhile, which is
It can remove, therefore pipeline not caused to damage, therefore for this method is compared to traditional pipe string method, there is group
The advantages of, group fast to speed is good to effect.
