Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a support device for an electric welding machine. Background Technology

[0002] In industrial production, welding machines, as key equipment for achieving metal joining, are widely used in many scenarios such as machinery manufacturing, construction, and automobile repair. To ensure the stability and safety of welding operations, welding machines typically require support and fixing devices.

[0003] Existing support devices for welding machines have several limitations in practical use. Regarding clamping and fixing, traditional supports often employ fixed or simply adjustable clamping structures, making them difficult to adapt to different specifications and models of welding machines. Either the fixed clamping size prevents compatibility with larger or smaller welding machines, or precise alignment during adjustment is difficult, resulting in insecure fixing of the welding machine, affecting welding accuracy and posing safety hazards. Furthermore, these clamping structures are often inconvenient to assemble and disassemble, consuming significant time and manpower, thus reducing work efficiency. In terms of height adjustment, the height adjustment function of existing supports is also unsatisfactory. Some supports use manual adjustment, which has low precision and cannot meet the specific height requirements of different welding operation scenarios. Utility Model Content
