Description

Technical Field

[0001] The invention relates to the technical field of metal cabinet welding, and in particular to a metal cabinet body electric welding device with precise positioning and a method thereof. Background Art

[0002] Material storage cabinets are cabinets specially used for storing and managing materials, tools and equipment, and are widely used in industries, warehouses, laboratories, shops and other places. They can help improve space utilization, keep items neat, and facilitate management and access. Metal cabinets generally need to be fixed by welding. The common welding method is to weld with a manual handheld electric welder or welding device.

[0003] For example, Chinese patent application CN117718642A discloses a metal safe cabinet welding and forming device, which includes a cabinet body, which is composed of a cabinet body and a back plate. A first U-shaped welding seam is formed on the outer peripheral surface of the cabinet body, and a second U-shaped welding seam is formed at the joint of the back plate and the cabinet body. The first welding seam and the second welding seam are respectively located in two vertical surfaces perpendicular to each other, and the first welding seam and the second welding seam are connected. The cabinet body is slidably assembled in a frame along a direction parallel to the first welding seam, and a welding gun is mounted directly above the first welding seam. The cabinet body and the welding gun make synchronous relative motion along a direction parallel to the first welding seam, and the welding gun contacts the first welding seam and the second welding seam in turn in one direction to form a continuous weld without breakpoints.

[0004] However, when the metal safe cabinet body welding and forming device is used, it cannot weld all surfaces of the metal safe cabinet body, but only welds the vertical facades, and cannot accurately position the welds, which easily leads to crooked welding, and cannot adapt to metal safe cabinet bodies of various sizes.
