Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to an edge and corner grinding equipment with a protective structure. Background Art

[0002] Edge grinding equipment is a mechanical device used to remove burrs, sharp edges and uneven surfaces at corners. They are designed to provide smoother, more uniform and safer edge processing, and are commonly used in industries such as metal processing, woodworking, and plastic processing. After operations such as industrial robots and composite processing equipment manufacturing, the finished workpieces also need to be polished to make them more durable.

[0003] The existing edge and corner grinding equipment uses a clamp to clamp the workpiece to be ground, and then grinds the workpiece with a grinding disc. However, when grinding is completed, the workpiece fixed by the clamp will be blocked by the clamp's claws, and the clamp needs to be loosened to adjust the position of the workpiece for grinding again, which is not convenient enough, and the waste chips generated during grinding can easily cause injuries to the workers.
