[0001] The utility model relates to the technical field of automobile part processing, in particular to a clamping device for welding and assembling an automobile rear floor. Background Art
[0002] The automobile rear floor is an important part of an automobile. It is located at the bottom of the vehicle trunk and plays a role in supporting and protecting the vehicle body. It is usually made of materials such as steel and aluminum alloy, and has high strength and durability.
[0003] After the automobile rear floor goes through the punching die, it still needs to be welded. After the rear floor is placed on the welding table, it is not convenient to unload the material because it is clamped tightly. At the same time, the welding table is generally directly set at the bottom of the welding machine, and there is a certain risk when placing and taking the rear floor. In addition, after the plates forming the rear floor are placed on the welding table, since the positions cannot be adjusted, it is difficult to ensure the tightness between the plates, and there will be a problem of large weld seams, thereby increasing the welding difficulty. Content of the Utility Model
