[0023] In actual application, the flatness of the adjustment plate 2 is adjusted by adjusting the module 3, so as to adjust the flatness of the welding plane of the welding fixture 7; in actual use, when one welding fixture 7 is in a welding working state, the other welding fixture 7 is in a loading state; when it is necessary to switch the positions of the two welding fixtures 7, the rotary drive mechanism 4 drives the rotary table 5 to exchange the positions of the two welding fixtures 7, so as to facilitate the loading and unloading of the workpiece, thereby improving the welding efficiency. Among them, the partition plate 6 separates the two welding fixtures 7, plays a protective role, avoids sparks and the like from splashing during welding, and protects the safety of the operators. The utility model has good safety performance. By rotating and switching the two welding fixtures 7, the efficiency of loading and unloading is improved, and the flatness of the welding fixture 7 can be adjusted, which can meet different welding flatness requirements and improve the welding quality.

[0024] Preferably, the partition plate 6 is a transparent plate, and the operator can observe the welding condition of the workpiece clamped by one of the welding fixtures 7 through the partition plate 6 .

[0025] In this embodiment, the adjustment module 3 includes an externally threaded sleeve 8 that threads through the adjustment plate 2 and a locking bolt 9 that is threadedly connected to the base 1.

The two ends of the externally threaded sleeve 8 respectively contact the top surface of the base 1 and the nut of the locking bolt 9. The externally threaded sleeve 8 can rotate between the nut of the locking bolt 9 and the base 1.

[0026] In actual application, when it is necessary to adjust the flatness of the adjustment plate 2, the external threaded sleeve 8 of the adjustment module 3 is rotated so that the external threaded sleeve 8 is threadedly connected to the adjustment plate 2, and the adjustment plate 2 can make slight lifting and lowering movements (fine-tuning) along the external threaded sleeve 8 to adjust the flatness of the adjustment plate 2, thereby adjusting the flatness of the welding plane of the welding fixture 7.
