Description

Technical Field

[0001] The invention relates to the technical field of vehicle body assembly processing, in particular to a vehicle body welding and grinding device. Background Art

[0002] Body welding is one of the indispensable steps in vehicle manufacturing, but the joints after welding are easily affected by corrosion, oxidation and rust. It is well known that during the vehicle modification process, the body frame does not undergo secondary electrophoresis; in order to extend the service life of the body and ensure the safety performance and appearance quality of the whole vehicle, the body welding parts must be treated with anti-corrosion. The rust on the welding parts is mainly caused by the uneven gaps in the welding parts, which directly leads to insufficient contact of the sprayed anti-corrosion paint at the welding parts, especially the phenomenon of bubbles missing between the welds. Therefore, welding, grinding and flushing of the body parts can effectively avoid the later corrosion of the body welding parts. However, there is currently no single equipment that can meet all the above processing requirements.
