Description

Technical Field

[0001] This utility model relates to the field of edge grinding machine technology, and in particular to a bearing edge grinding machine for bearing processing. Background Technology

[0002] A bearing flange is a narrow shoulder that protrudes from the raceway surface and is parallel to the rolling direction. It is primarily used to support and guide the rolling elements, ensuring their stable operation within the bearing. The flange prevents excessive rolling of the rolling elements from rolling off the outer ring, thereby enhancing the bearing's service life and stability.

[0003] Bearing flanges are an important structural component of bearing races, and their machining accuracy directly affects the bearing's axial load capacity and service life. In existing technologies, traditional grinding machines suffer from the following problems:

[0004] Bearing edge grinding machines often rely on manual workpiece clamping, resulting in low clamping efficiency, poor consistency, and frequent positioning adjustments by operators, leading to high labor intensity. Furthermore, traditional grinding machine coolant spray systems are typically single-point or linearly distributed, making it difficult to evenly cover the grinding area. This can easily cause localized overheating and deformation of the workpiece, while grinding debris remaining in the machining area exacerbates wheel wear and affects machining accuracy.
