TECHNICAL FIELD
[0001] The utility model relates to metal surface polishing technical field especially, relates to a kind of ultrasonic vibration auxiliary abrasive flow polishing device. BACKGROUND
[0002] Gear is widely used in precision mechanical transmission field as a complex metal component, and polishing is an important surface treatment method, aiming at improving the smoothness and precision of gear surface to reduce friction and improve transmission efficiency. The main methods of gear polishing are abrasive polishing, chemical polishing and electrolytic polishing. The traditional gear abrasive polishing has high precision requirements for abrasive equipment, and the efficiency is low. Chemical polishing and electrolytic polishing equipment are simple, and can remove the oxide on the metal surface, but the chemical pollution produced during processing is not conducive to the protection of ecological environment. Therefore, new gear polishing methods such as ultrasonic polishing and fluid polishing are generated. Ultrasonic polishing is a method of polishing gear surface by using ultrasonic vibration and fine abrasive medium. Ultrasonic vibration can produce high-frequency vibration on the gear surface, effectively removing surface defects and small particles, but the polishing time is long due to the limitation of ultrasonic power. The efficiency of abrasive flow polishing is high, but the flow path of abrasive is unstable, which makes the surface polishing uneven.
[0003] For gears with high surface hardness and high overall material hardness, it is difficult to meet the requirements of smoothness and precision using a single polishing method. People have adopted a variety of polishing methods combined with polishing methods, such as magnetorheological polishing and ultrasonic vibration abrasive flow polishing. Composite polishing usually requires special devices or is polished in different processes, which is less operable and has high economic cost.
[0004] The existing ultrasonic vibration auxiliary abrasive flow polishing technology is not mature enough. Although it combines some advantages of ultrasonic polishing and abrasive flow polishing, it is only realized in the laboratory and has not been widely applied. Therefore, it is urgent to develop and improve the ultrasonic vibration auxiliary abrasive flow polishing device to provide higher application value for polishing the complex metal surface of similar gear components.
