Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and particularly relates to a bearing processing grinding equipment and method. Background Art

[0002] In the field of mechanical manufacturing, bearings, as key components, are widely used in various rotating machinery, and their processing quality directly affects the performance and service life of mechanical equipment. Grinding is a key process in the bearing manufacturing process, and it plays a crucial role in ensuring the dimensional accuracy, surface roughness, and shape accuracy of bearings.

[0003] Traditional bearing processing grinding equipment has many problems in practical applications. In terms of bearing fixation, most equipment uses a simple external clamping method, which easily causes small displacements and deformations of the bearings during grinding. Due to the structural characteristics of bearings, the concentricity requirements of their inner and outer rings are extremely high. Once there is a deviation during fixation, it will be difficult for the concentricity of the inner and outer rings of the ground bearings to meet the standards, thereby affecting the rotation accuracy and stability of the bearings.

[0004] In terms of grinding uniformity, traditional equipment often relies on a single grinding method and is difficult to achieve comprehensive and uniform grinding of the outer ring of the bearing. Due to uneven distribution of grinding forces, it is easy to cause local overheating, burning, etc. on the bearing surface, affecting the surface quality and material properties of the bearings. In addition, the automation level of traditional equipment is relatively low, and most operations require manual intervention, which not only increases the labor intensity of workers but also easily causes processing errors due to human factors. Therefore, we propose a bearing processing grinding equipment and method to solve the above problems. Summary of the Invention

By repeating the above steps, the bearings on the rotating disk can be ground in sequence.

[0024] The beneficial effects of the present invention:

[0025] 1. Through the cooperation of the ingeniously arranged arc-shaped support plates and the drive mechanism, precise and strong extrusion fixation of the inner wall of the bearing can be achieved during the grinding process. This method fully considers the structural characteristics of the bearing, ensuring that the bearing does not undergo any tiny displacement and deformation during the entire grinding process, effectively guaranteeing the concentricity of the bearing, greatly improving the machining accuracy, and enabling the produced bearings to better meet the usage requirements of high-precision mechanical equipment.

[0026] 2. It has the performance of uniform and high-quality grinding. The cooperative working mode in which the drive motor drives the bearing to rotate and the rotating motor drives the grinding roller to rotate can achieve all-round and dead-angle-free grinding of the outer ring of the bearing.
