[0002] In the manufacturing industries of electrical equipment and environmental protection equipment, gas-insulated switchgear and environmental protection cabinets are key components. The quality and precision of the internally connected copper bars directly affect the performance and safety of the equipment. As a conductive material, copper bars need to undergo precise cutting, bending, and assembly processes during processing to ensure the stability and reliability of electrical connections. However, in the actual production process, the end joints of copper bars often have uneven problems, which not only lead to poor contact and increased resistance during installation, but even pose potential safety hazards.

[0003] Traditionally, the leveling treatment of copper bar end joints mostly uses manual operations, such as using tools like hammers and files for knocking and grinding. This method not only has a high labor intensity and low efficiency, but also is difficult to ensure the consistency and precision of the leveling effect. Especially for mass-produced gas-insulated switchgear and environmental protection cabinets, it has become a bottleneck restricting production efficiency and quality improvement.

[0004] In addition, during the manufacturing process of gas-insulated switchgear and environmental protection cabinets, the length and position of copper bars need to be precisely adjusted according to specific designs. The processing of metals often shows inconsistencies in multiple directions, which will affect the internal connections of gas-insulated switchgear and environmental protection cabinets and cannot meet the requirements of electrical connections and spatial layouts. Traditional adjustment methods often rely on manual measurement and adjustment, and it is difficult to achieve rapid and precise adjustment in the axial and vertical directions, further affecting production efficiency and product quality.
