Problems solved by technology

Thus there are the following problems: 1. Due to the need for multiple assembly, errors caused by repeated positioning are unavoidable
2. Due to the thin wall of the parts to be welded, it is easy to cause deformation of the parts during multiple disassembly and assembly processes
3. Due to the need for multiple assembly and multiple welding, the welding operation takes a long time and the efficiency is low
4. Due to the need for multiple sets of fixtures (or tooling), the cost increases

Abstract

A clamp for welding multi-sectional thin-wall parts comprises a base, a limit ring, a pull rod, a first taper mandril, a lower slide block, a lower expanding block, a second taper mandril, an upper slide block, a guide block, an upper expanding block, a short shaft, a sleeve, a pressing plate, a first nut, a pressing ring, a second nut, a welding device connection shaft, a pressing plate, a pressing cover and a third nut. By means of the clamp for welding the multi-sectional thin-wall parts, the welding of the multi-sectional thin-wall parts can be achieved by primary assembly and welding.

Description

technical field [0001] The invention belongs to a welding fixture, in particular to a fixture for welding multi-section large thin-walled parts (diameter>600mm). Background technique [0002] With regard to the welding of multi-section large thin-walled parts, the prior art requires multiple sets of fixtures (or tooling), and the welding of all parts is completed in a manner of multiple assembling and multiple welding. For example, if five sections of large thin-walled parts need to be welded together, at least three sets of fixtures (or tooling) are required for three assembly and three welding. Therefore, there are the following problems: 1. Due to the need for multiple assembly, errors caused by repeated positioning inevitably exist. 2. Due to the thin wall of the welded parts, it is easy to cause deformation of the parts during multiple disassembly and assembly processes. 3. Due to the need for multiple assembly and multiple welding, the welding operation takes a lo...
