Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a clamping mechanism used for welding an automobile seat frame. Background Art

[0002] The so-called car seat is a seat for sitting in a car. The seat is an important component of the car. It is mainly composed of a backrest and a cushion. The main components of the backrest and the cushion are the backrest frame, the cushion frame, the foam layer and the surface layer, etc. The frame is composed of a U-shaped tube and a connecting tube. The U-shaped tube and the connecting tube need to be welded together to form the car seat frame. When welding the car seat frame, a clamp is required to clamp it and fix it.

Vehicles on the market are divided into private cars, engineering vehicles, racing cars and other types, and the thickness of their car seat frames is also different. Therefore, during welding, the car seat frame may be too thick or too thin, resulting in unstable clamping. In view of this, we propose a clamping mechanism for welding car seat frames.
