Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the utility model provides a group sets up instrument for nuclear power trunk line and spoon shape welding process, including group to support 1, location axle 2, stay bolt 4 and positioning bolt 3; the positioning shaft 2 is fixedly sleeved with a positioning wafer 7, the conical surface of the positioning wafer 7 is attached to the conical surface of the inner conical hole of the cold section pipe fitting, the positioning shaft 2 is of a hollow tubular structure, one end of the positioning shaft is communicated with the argon bottle, and the other end of the positioning shaft is connected with a positioning bolt 3; the positioning disk 7 and the positioning shaft 2 are used for being connected with a through hole 11 for argon to flow out is formed in the side wall of the positioning shaft 2 between one ends of the positioning bolts, the group is formed by connecting a lower circular plate 8 and an upper cross beam 9 through a supporting column 10 to the support 1, bolt holes for mounting supporting bolts 4 are formed in two ends of the upper cross beam 9 of the group support 1, the supporting bolts 4 abut against the inner wall of a main pipeline, and the positioning shaft 2 is connected with the lower circular plate 8 through the positioning bolts 3.
