Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an automatic welding machine for welding bimetal parts in a circuit breaker. Background technique [0002] Bimetal parts (also known as bimetal components) are key parts used in miniature circuit breakers for switching on and off. Such as figure 1 As shown, the structure of the bimetal component includes an arc strike assembly and a contact assembly. The arc strike assembly includes a bimetal sheet 1a, a terminal plate 4a, a U-shaped connecting piece 5a and an arc strike plate 6a; the contact assembly includes a copper braided wire 2a and moving contact 3a; composed of six parts in total, one end of the U-shaped connecting piece 5a is welded to the terminal plate 4a, and the other end of the U-shaped connecting piece 5a is overlapped with the bimetallic sheet 1a and the end of the arc strike plate 6a and then welded together , and then weld one end of the braided copp...
