Abstract

The invention discloses a microcapillary membrane assembling, positioning and welding tool based on C-shaped positioning wires. The microcapillary membrane assembling, positioning and welding tool comprises an upper positioning mechanism, an upper positioning disc, a stand column, a lower positioning disc and a lower positioning mechanism. The upper positioning disc is supported on the lower positioning disc through three or more stand columns, and the three or more stand columns are evenly arranged in the circumferential direction of the disc body. An upper positioning mechanism and a lower positioning mechanism are installed on the upper positioning disc and the lower positioning disc respectively and used for being jointly connected with a plurality of C-shaped positioning wires and achieving tensioning of each C-shaped positioning wire. Wherein the C-shaped positioning wire is used for assembling, positioning and welding a microcapillary membrane, and the C-shaped positioning wire is formed by uniformly pressing a plurality of C-shaped grooves in the single side of a positioning wire blank along the axial direction through a C-shaped positioning wire forming tool.

Description

technical field [0001] The invention relates to the technical field of engine manufacturing, in particular to a C-shaped positioning wire-based microtube diaphragm assembly positioning welding tool. Background technique [0002] Such as figure 1 As shown, the microtube diaphragm is an important part of the self-cooling of the composite precooling engine. Each group of microtube diaphragms consists of 880 to 1000 involute microtubes with a diameter of Φ1mm, a wall thickness of 0.05mm, and a length of 900 to 1000mm. tube (such as figure 2 As shown) and the gas-collecting components at both ends are brazed, and the assembly and welding of the microtube diaphragm is an international problem. At present, many domestic manufacturers are carrying out research on this type of engine. Therefore, it is very important to carry out research on the assembly brazing and welding technology of microtube diaphragms. [0003] The walls of microtubes are thin, fragile and easy to deform. I...
