Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, and more specifically, to a flange product grinding machine. Background Art

[0002] Flanges are common connectors in engineering, used to connect pipes, valves, pumps, and other equipment to ensure a tight seal. Flange grinders are specialized equipment used to process flanges and other parts. They are primarily used to precisely grind flange surfaces to achieve the required high standards of flatness and surface finish. However, some grinding machines still have shortcomings in actual operation. For example, when grinding flanges, some existing three-jaw chucks and other centering clamping devices are used to secure the flange. This typically requires the flange to be placed in the center of the fixture and clamped with tightened, centering jaws. However, since both ends of the flange need to be ground, the clamping devices on these grinding machines cannot automatically flip the flange. Therefore, workers must first loosen the chuck, manually flip the workpiece, and then readjust the jaws to secure it each time they need to change the grinding surface. This process is not only time-consuming and labor-intensive, reducing production efficiency, but also poses potential safety hazards and increases the risk of work-related injuries.
