Description

Technical Field

[0001] The invention relates to the technical field of automobile chassis, in particular to an automatic welding device and a welding method for an automobile chassis. Background Art

[0002] The automobile chassis consists of four parts: transmission system, running system, steering system and braking system. The function of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the automobile, and receive the power of the engine to make the car move and ensure normal driving. It is used to support and install the automobile engine and its various components, assemblies and instruments and equipment, thereby forming the overall shape of the electric test / inspection vehicle.

[0003] For example, an automatic welding device for automobile chassis disclosed in publication number CN112975259A can flip the automobile chassis when welding the automobile chassis, which is convenient for accurate and diverse welding positions. In order to facilitate manual autonomous rotation and adjustment of the flipping angle of the automobile chassis, the flipping mechanism can be manually controlled to flip the automobile chassis clamped by the clamping mechanism, which saves time and effort and has strong flexibility, thereby facilitating multi-point welding. The power mechanism drives the welding mechanism to move in all directions, so that there are omissions during welding. This device is suitable for use in workshop assembly lines for mechanized production welding, has a simple structure, and is difficult to use.

[0004] Although it can manually and autonomously rotate and adjust the flip angle of the automobile chassis to facilitate multi-point welding, it needs to be positioned and supported when the automobile chassis is welded. However, the above patent and most welding equipment on the market are not provided with a corresponding positioning support structure, and cannot be adjusted according to automobile chassis of different types and sizes. The scope of application is narrow and the flexibility is poor. When the flip angle of the automobile chassis is manually adjusted, the user's workload will be further increased and the work efficiency will be reduced. Therefore, an automatic welding device and welding method for automobile chassis are urgently needed to be developed. Summary of the invention
