Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a brazing precision positioning tool. Background Art
[0002] Brazing is a type of welding method. It uses a metal material with a lower melting point than the parent material as the brazing material. The brazing material is placed at the gap position of the parent material, and a heating device is used to make its temperature higher than the melting point of the brazing material and lower than the melting temperature of the parent material. At this time, the brazing material is in a liquid state, which can wet the parent material and fill the joint gap. Under the capillary force, the gap at the joint surface forms a fiber gap. Before the fiber gap is completely solidified, the fiber material in the fiber gap and the base metal melt and diffuse with each other. After cooling and solidification, it is firmly bonded and diffused with the parent material to achieve the connection of the weldment. It is often used for the connection of pipeline components, with small deformation, smooth and beautiful welding surface, and welding gap.
[0003] During the manual brazing process, the position of the dimensional elements of the welded components cannot be guaranteed. The welding precision is insufficient due to the small displacement of the two welded parts due to the unfixed state. This is not only not conducive to improving labor efficiency, but also affects the dimensional accuracy of the welded parts, thus affecting product quality and reducing production efficiency. In addition, during brazing, various problems such as uneven distribution of the brazing material and easy burns to the human body may occur. The operation is not practical and convenient, and safety cannot be guaranteed, which will also cause many inconveniences. Utility Model Content
