Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of automatic grinder for ring parts, belong to polishing equipment technical field. BACKGROUND

[0002] Rust on the surface of ring parts, such as bearing inner and outer rings, not only seriously affects its aesthetic, making the surface rough, but also can reduce the overall quality of the product. In addition, the texture of rust is relatively loose, easy to adsorb dust and moisture, which will increase the risk of further rust and corrosion of ring parts, thereby shortening its service life. If rust is not removed in time, it may also have adverse effects on the performance of ring parts, such as reducing its wear resistance and fatigue strength.

[0003] To improve the aesthetic, service life and performance of ring parts, we need to regularly polish the rust on ring parts. By polishing, surface impurities such as rust and oxide scale can be removed, restoring the original metal luster and texture of the ring part surface. This not only improves the hardness and corrosion resistance of the ring part, but also prolongs its service life. Regularly polishing rust is also one of the important measures to maintain and protect ring parts.

[0004] The traditional way of polishing rust on ring parts mainly relies on manual operation, which has several problems. First, workers need to hold sandpaper to work around the ring part in a stooped or crouched position. This posture not only easily leads to fatigue, increasing labor intensity, but also can have some impact on physical health for workers who work for a long time. Second, the traditional manual polishing method is low in efficiency and difficult to meet the needs of mass production. In a mass production environment, the efficiency bottleneck of manual polishing will be more obvious, affecting production efficiency and product quality. In addition, during the polishing process of ring parts, since the starting and ending positions are not fixed, workers may miss polishing some areas. This will result in uneven surface treatment of ring parts, affecting product quality. To ensure uniform surface treatment of ring parts, workers need to have superb skills and rich experience, but such skilled and experienced workers are often scarce and costly.

[0005] In addition, there are some automatic polishing equipment on the market, for example, the application number is 201710148294.6, the invention patent discloses a rust removal polisher for automobile hub bearing, which comprises a base, a motor and a support column are installed on the base, the motor output end is movably penetrated through the lower section of the support column and extends outward horizontally, a polishing shaft is movably penetrated through the upper section of the support column and is parallel to the motor output end, a gear and a stop block are arranged on the motor output end and located on both sides of the support column respectively, a pinion is arranged on one end of the polishing shaft and matched with the gear, and a polishing head matched with the bearing is arranged on the other end of the polishing shaft. The polishing equipment has obvious limitations when processing the annular part. Although it can process the rust on the bearing outer ring, due to the design limitation and functional limitation, it cannot polish the whole annular part comprehensively.

[0006] Therefore, it is necessary to seek a more efficient, safe and reliable rust polishing equipment. Utility model content
