Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parts processing, and in particular to a grinding device for producing and processing general parts. Background Art
[0002] Bearings are a type of universal component. my country's bearing production technology is becoming increasingly mature. Rolling bearings are generally composed of four parts: an outer ring, an inner ring, rolling elements, and a cage. Strictly speaking, they are composed of six major parts: an outer ring, an inner ring, rolling elements, a cage, a seal, and lubricating oil. In simple terms, as long as they have an outer ring, an inner ring, and rolling elements, they can be defined as rolling bearings. After the bearing is prepared, the outer ring of the bearing needs to be ground and polished.
[0003] A grinding device for bearing processing proposed in the publication number CN 212420733 U has a reasonable structural design and is easy to use. It can quickly and effectively grind the bearing after clamping without too much manual operation, thereby improving work efficiency and reducing the labor intensity of workers. The grinding is uniform, ensuring the fineness of the bearing grinding, which is conducive to improving product quality and can meet the needs of large-scale bearing grinding processing. However, in actual use, the above case cannot stably clamp bearings of different sizes due to the fixed curvature of the clamping sleeve, resulting in poor applicability. In the actual grinding and polishing process, it is impossible to automatically grind the two end faces of the bearing, resulting in its grinding efficiency being affected. Therefore, it is necessary to propose a grinding device for the production and processing of general parts to solve the above problems. Utility Model Content
