Piping truss welding and thermal treating positioning device and method

Abstract

The invention relates to a piping truss welding and thermal treating positioning device and method. The device comprises a mounting baseplate, a supporting beam, a main beam, supporting beam fixing rods and a mounting baseplate fixing rod, the supporting beam is arranged above the mounting baseplate, the main beam is arranged between the mounting baseplate and the supporting beam, the supporting beam fixing rods are mounted between two ends of the supporting beam and the mounting baseplate respectively, and the mounting baseplate fixing rod is arranged between the mounting baseplate and the main beam; an X-axis limiting block, a Y-axis limiting block and a bottom shaft Z-axis limiting block which are perpendicular to each other are arranged at the end of the mounting baseplate. The devicecompletes high-quality welding of a piping truss, cracks are avoided, and size accuracy and size stability of the truss are ensured.

Description

technical field [0001] The invention relates to a positioning device and positioning method for piping truss welding and heat treatment, which are mainly used for piping truss welding and post-welding heat treatment, for ensuring the position size of each part and the coordinate size of the piping system, preventing the deformation of the parts, and can be used It can also be used for heat treatment in welding. Background technique [0002] The tube truss is an important structural part of some aerospace vehicles, which bears the load of all engines and projectiles. The reliability of the tube truss directly determines the reliability of the launch vehicle, and the most critical part of the manufacturing quality of the tube truss is assembly. Welding process technology, but due to the structural characteristics of the truss welds concentrated on the pipe system, the local stress and strain during the welding process not only directly affect the weld area and are prone to cra...

[0002] The tube truss is an important structural part of some aerospace vehicles, which bears the load of all engines and projectiles. The reliability of the tube truss directly determines the reliability of the launch vehicle, and the most critical part of the manufacturing quality of the tube truss is assembly. Welding process technology, but due to the structural characteristics of the truss welds concentrated on the pipe system, the local stress and strain during the welding process not only directly affect the weld area and are prone to cracks, but also affect the accuracy of the shape and size of the truss and the size Stability is affected and it is difficult to control. At the same time, the size of the parts is large and the structure is complex, which puts forward higher requirements for welding quality
