Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an adjustable bearing inner ring turning fixture. Background Art

[0002] Bearing inner ring turning is a machining process. The bearing inner ring is an important component of the bearing. Turning is the use of lathes and other equipment to cut the bearing inner ring through the relative motion between the rotating workpiece and the tool.

[0003] The bearing inner ring turning fixture is a device used to fix and position the bearing inner ring during the turning process. Its main function is to ensure that the bearing inner ring can maintain a stable position during turning without displacement or shaking, thereby ensuring processing accuracy and surface quality.

[0004] Existing turning fixtures are only suitable for bearing inner rings of specific sizes and cannot be quickly adjusted to accommodate products of different specifications. For example, when a different bearing inner ring model needs to be processed, the entire fixture may need to be redesigned and manufactured, resulting in increased time and cost. This makes it difficult to respond promptly to small-batch, high-variety production needs. Furthermore, the fixture has low adaptability and can only be used for workpieces with relatively standard shapes. For irregular shapes or workpieces with poor precision, the processing quality cannot be guaranteed, reducing production efficiency. Therefore, an adjustable turning fixture for bearing inner rings is proposed to address these issues. Utility Model Content
