Detailed Description
As shown in fig. 1-7: a sectional flange assembling and welding tool comprises an assembling platform 1, an outer frame plate 2, a rotary hinge 3, a pressing plate 4 and a fixing clip 5; the outer frame plate is arranged on the upper portion of the assembling platform, the inner circle of the outer frame plate is matched with the sectional flange to be installed in size, the pressing plate is located on the upper portion of the outer frame plate, one end of the pressing plate is connected with the assembling platform through rotating the hinge, and the other end of the pressing plate is connected with the assembling platform through a fixing clip.
Further, the rotary hinge rotates horizontally or vertically.
Furthermore, the pressing plate is T-shaped, one end of the pressing plate is provided with a rotary hinge, and the other two ends of the pressing plate are connected with a fixed clip.
Furthermore, the fixing clip is Y-shaped, and the lower end of the fixing clip penetrates through the pressing plate and is fixed by welding.
The installation method of the sectional flange assembling and welding tool comprises the following steps:
the method comprises the following steps: according to the size of the flange needing to be assembled and welded in large batch, an assembling platform is arranged and leveled;
step two: determining the size of the outer frame plate according to the diameter of the flange outer ring and the allowed maximum tolerance;
step three: during assembly, the sectional flanges are assembled into a whole around the inner circle of the outer frame plate respectively, and spot welding is firm after dimension checking; when the flange is placed, a welding seam gap 6 and a placing arc striking plate are reserved, so that the error welding with an outer frame plate is prevented when the flange is welded;
