[0002] The explosion-proof ball is a type of explosion-proof container in explosion-proof disposal equipment. After discovering explosives or suspected explosives, they can be temporarily placed in the explosion-proof ball to prevent them from suddenly exploding and causing harm and loss to surrounding life and property. The explosion-proof ball shell requires a welding process during processing. During welding, a positioning structure is required to limit the explosion-proof ball shell. The positioning structure of existing explosion-proof ball shell processing and welding equipment often uses two splints to fix the explosion-proof ball shell. This method has a simple structure, but in actual use, the contact area between the splint and the explosion-proof ball shell is small, which leads to low positioning stability. Therefore, it is necessary to design and modify the positioning structure of the explosion-proof ball shell processing and welding equipment to effectively prevent the phenomenon of poor positioning effect.
