Welding mechanism of semiconductor stander

The utility model relates to mechanical welding and positioning equipment, in particular to a positioning device required when a semiconductor bracket is welded. The welding mechanism aims to provide a welding mechanism of the semiconductor stander, which has simple structure, and can lighten the labor intensity, improve the efficiency and avoid welding deformation as far as possible. The welding mechanism of the semiconductor stander is provided with a bottom plate, the upper part of the bottom plate is provided with a first positioning assembly, two sides of the bottom plate are respectively provided with a second positioning assembly, a third positioning assembly and a fourth positioning assembly, and the middle on the bottom plate is also provided with an auxiliary bearing assembly. The mechanical welding and positioning equipment has the advantages that products can be clamped in one step, and after a workpiece is placed on a welding platform, the space position of the workpiece can be confirmed through a combined shaft, a locating pin and a limiting stop pin, thereby not only improving the welding efficiency, but also effectively avoiding welding deformation.
