Arc edge milling structure

The utility model belongs to the technical field of edge milling machines, and particularly relates to an arc edge milling structure. In order to simultaneously achieve the purposes of arc-shaped edge milling and linear edge milling in a limited space and site without additionally increasing more operating cost, the utility model provides a simple structural assembly for arc-shaped edge milling, and an arc-shaped edge milling structure matched with a linear edge milling platform is designed on original linear edge milling equipment. A rotating seat plate in the arc edge milling structure can rotate on an arc edge milling platform and simultaneously drives an arc bearing plate fixedly matched with the rotating seat plate to rotate along an arc track, and the arc bearing plate is used for fixing a component to be subjected to edge milling. The arc edge milling structure is easy to install and low in cost, arc edge milling operation can be conducted by installing the arc edge milling structure on an edge milling
