Description

Technical Field

[0001] This utility model relates to the field of automotive floor welding technology, specifically a stable support mechanism for automotive floor welding. Background Technology

[0002] As we all know, the existing car floor is a basic part of the car interior, used to support the vehicle's internal structure. It is usually made of metal or plastic, and sometimes includes sound insulation materials to reduce noise. In the automotive manufacturing industry, floor welding is a crucial step that is directly related to the overall quality and safety of the car.

[0003] However, existing support mechanisms for automotive floor welding are often unable to adapt to automotive floors of different shapes and sizes. Furthermore, the position and height of the support mechanism need to be frequently adjusted manually during the welding process, which not only prolongs the welding time and reduces production efficiency, but also affects the welding accuracy and aesthetics, damages the structure of the automotive floor, and may even cause the automotive floor to move or deform during the welding process, thus reducing its service life.
