Welding fixture applied to chip assembly

The utility model discloses a welding fixture applied to a chip assembly, which relates to the field of welding process and can clamp and fix the chip assembly and ensure the forming quality of the chip assembly in the welding process. Comprising a clamp body, a pressing block and a limiting block, in the clamping state, the pressing block and the limiting block are connected with the clamp body to form a clamping chamber for clamping and fixing a chip assembly, the clamping chamber is provided with a plurality of clamping faces, the multiple clamping faces are matched with the corresponding side faces of the chip assembly, and the clamping faces are matched with the corresponding side faces of the chip assembly. And the pressing plate is used for abutting against each side face of the chip assembly so that the chip assembly can be kept in an optimal forming structure in the welding process. Through the cooperation of the clamp body, the pressing block and the limiting block, all parts of the chip assembly ar
