Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a flange grinding machine for machining bearing inner rings. Background Technology

[0002] The inner ring flange grinder is one of the equipment used to process bearings. It is mainly used for rough grinding or fine grinding of the flanges of roller bearings.

[0003] Currently, most bearing inner ring machining edge grinders rely on air blowing and water washing to clean iron filings. This causes the iron filings to be blown into the air during cleaning, affecting the surrounding environment. At the same time, the water washing process also causes the iron filings to accumulate, making them prone to rusting. This makes cleaning more difficult. To address these issues, there is a need for a bearing inner ring machining edge grinder that can easily clean iron filings.

[0004] For example, Chinese Patent CN 116352526 A describes a flange grinding machine for machining bearing inner rings. It includes a connecting base, a protective cover connected to the end face of the connecting base, a controller connected to the side wall of the protective cover, and a flange grinding machine connected to the end face of the connecting base and within the inner cavity of the protective cover. A dust removal structure is provided on the worktable of the flange grinding machine, and groove cleaning structures are symmetrically arranged on the connecting base and on both sides of the flange grinding machine. This invention, by incorporating a dust removal structure and a groove cleaning structure into the flange grinding machine for machining bearing inner rings, utilizes the drive motor, servo motor, and rotation motor within these structures to remove metal shavings through a transmission structure. This design makes cleaning metal shavings more convenient during the use of the flange grinding machine for machining bearing inner rings, thus solving the problem of inconvenient metal shavings cleaning.

[0005] However, the grinding machine's positioning is not flexible enough and cannot meet the processing requirements of different sizes. Utility Model Content
