Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, in particular to a grinding device for automobile sheet metal parts. Background Art

[0002] Automotive sheet metal parts, that is, metal parts on cars, are important components of the car structure and exterior body coverings, and are mainly made through different sheet metal processing technologies. After processing, automotive sheet metal parts need to be ground accordingly to remove some protruding edge materials generated during stamping, bending, cutting, stretching, welding and other operations, so as to make the outer surface of the automotive sheet metal parts smoother, improve its overall aesthetics and reduce the difficulty of subsequent processing. When grinding automotive sheet metal parts, a large amount of debris will be generated, and the debris will fly around the grinding device with the grinding disc. However, most common grinding devices are not equipped with corresponding protective structures, so that the debris may cause certain harm to the workers around the grinding device, and in serious cases, industrial accidents may occur.

[0003] Secondly, the grinding operation of automobile sheet metal parts will also produce a certain amount of smoke and dust, which will escape to the production area, causing a certain impact on the health of the workers in the production area. If things go on like this for a long time, it will cause the workers to suffer from occupational diseases.
