Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum brazing welding, in particular to a positioning tool for vacuum brazing welding. Background Art
[0002] Vacuum brazing is an advanced welding technology that uses low pressure and high temperature conditions in a vacuum environment to connect metal materials together. It is mainly used for welding high-quality products and easily oxidized materials. Brazing requires high position accuracy. In order to ensure uniform and accurate brazing positions, positioning tooling is required.
[0003] The current vacuum brazing welding adopts direct high-temperature heating, which is to add brazing wire and apply flux, and then melt the brazing wire by high-temperature heating for welding. This process cannot ensure uniform welding inside the workpiece, and the heating temperature is too high, which can easily cause the workpiece to deform due to heat and is difficult to remove from the tooling.

[0008] By adopting the above technical solution, the fixing nut is used in conjunction with the threaded rod, and the nut can lock the threaded rod to keep the threaded rod in a moving position.
[0009] As a further description of the above technical solution: one end of the outer ring of the threaded push rod is threadedly connected with a locking nut, and the locking nut is located in front of the groove plate.
[0010] By adopting the above technical solution, the threaded push rod drives the fixed plate to move to position the workpiece. After the positioning is completed, the threaded push rod is fixed by the locking nut to avoid movement during the positioning process, which leads to inaccurate positioning.

[0015] As a further description of the above technical solution: a baffle is slidably connected to the inner side of the groove plate.
[0016] By adopting the above technical solution, the baffle plate and the fixing plate are used to clamp and position the large workpiece.
[0017] As a further description of the above technical solution: a threaded rod is threadedly connected to the inner side of the fixing nut, and one end of the threaded rod passes through the connecting plate and is connected to one side of the clamping plate.
[0018] By adopting the above technical solution, the threaded rod drives the clamping plate to clamp and position the small workpiece, and the fixing nut is used to fix the position.
