Description

Technical Field

[0001] This utility model relates to the field of switch structural component manufacturing technology, and in particular to a rotary welding positioning device. Background Technology

[0002] To ensure the reliable and stable operation of switches, they typically have internal covers for electromagnetic shielding and heat dissipation management. These covers are mostly made of galvanized steel sheet (SECC) or aluminum alloy, and are manufactured through processes such as stamping, bending, and welding. During the welding process, the positioning structure of the covers is usually a fixed design. When welding is required on all four sides, existing technologies generally employ two methods: first, manually and repeatedly adjusting the orientation of the covers to ensure that each side is sequentially within the range of the welding gun; second, using multiple welding guns to simultaneously weld the four sides. However, the former is cumbersome, inefficient, reliant on manpower, and prolongs the operation time; while the latter can improve efficiency, it requires multiple sets of welding equipment and corresponding control systems, significantly increasing equipment investment and production costs.

Furthermore, the clamping drive device drives the surrounding abutment frame to abut the edge, and the clamping plate increases the contact area, significantly enhancing the positioning rigidity and stability, which is conducive to improving the welding accuracy and consistency. The positioning structure can be linked with the front push drive device to achieve overall forward and backward movement, which facilitates the loading and unloading of the cover part outside the clamping area, simplifies the loading and unloading process, and improves the convenience and automation level of continuous operation.

When the rotating shaft 30 rotates to a specific angle, the locking rod 39 is moved back into the locking hole 41 by the angle locking drive device 38, so that the angular position of the positioning structure and the cover 34 can be locked.

[0046] To improve locking stability, angle locking drive devices 38 can be installed above and below the rotating frame 2, and the two corresponding locking rods 39 can cooperate with the two locking holes 41 synchronously.
