Abstract

The invention discloses a positioning tool for assembling a pipe fitting and a flange. The positioning tool for assembling the pipe fitting and the flange comprises a machine table, wherein the machine table is provided with two positioning seats which are oppositely arranged, at least one positioning seat is in sliding connection with the machine table, each positioning seat is provided with a reciprocating motion device, each positioning seat is provided with a first conical surface and a second conical surface which are coaxial, the first conical surfaces are used for positioning the flange, the second conical surfaces are used for positioning the pipe fitting, a positioning bolt is arranged on the outer side of each first conical surface, one end of each positioning bolt is provided with a third conical surface which abuts against the edge of a flange bolt through hole, a nut is arranged on the side, penetrating through the corresponding positioning seat, of each positioning bolt, and the nuts are matched with the third conical surfaces to press the flange on the end surfaces of the positioning seats. According to the positioning tool, the problems that the labor intensity is high, the working efficiency is low, and the assembling and positioning precision is low are solved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a positioning tool for assembling pipe fittings and flanges. Background technique [0002] During shipbuilding, such as figure 1 As shown, the purchased pipe fitting a and flange b will be welded into a finished product, and the finished product or the finished product and the finished product will be connected as the piping system of the hull. For the convenience of welding, the flange is directly socketed on the ends of both sides of the pipe fitting. However, there is a gap of 2-3mm between the outer diameter of the pipe fitting and the inner hole b1 of the flange. It is difficult to ensure the verticality of the pipe fitting and the end face of the flange by direct welding. Therefore, before the circumferential welding of the pipe fittings and the flange end faces, the assembly of the pipe fittings and the flanges needs to be positioned to ensure the perpendicularity of the pipe ...
