Ultrasonic surface rolling device for inner hole type parts

Abstract

An ultrasonic surface rolling device for parts with inner holes, comprising an ultrasonic power supply, a transducer, a horn, a working head, a workpiece, a spring, a baffle and a guide rail. One end of the transducer is connected to the ultrasonic power supply, and the other end of the transducer is connected to the horn. There is a working head at the end of the horn. The working head is in contact with the workpiece. It is the baffle plate, and the present invention uses springs to provide static pressure; the present invention uses rolling balls to replace the traditional sliding processing method, so that the rolling surface quality is significantly improved; the present invention uses longitudinal vibration horns, which can realize rolling on the surface of the inner hole pressure.

Description

technical field [0001] The invention relates to an ultrasonic surface rolling device for parts with inner holes, belonging to the field of mechanical processing. Background technique [0002] With the development of my country's industry and the continuous improvement of the degree of mechanization, people have higher and higher requirements for the automation level, work efficiency and work precision of machinery, and the processing quality of parts will determine the work precision, performance and service life of a part . The above requirements are all based on the premise of improving the machining accuracy of parts and their surface quality. Traditional finishing methods, such as: grinding, tumbling, clear grinding, polishing, etc., although they have improved the surface quality of parts to a certain extent, there is still a big gap compared with foreign technologies and processing effects. In the finishing process of various types of surfaces, it is more difficult to...

AI Technical Summary

Problems solved by technology

Typical processing methods such as abrasive flow processing have good processing efficiency and effect, but because the grinding medium used is viscoelastic abrasive, this leads to the limitation of its application range, and the inner hole surface of some parts is required not to be stained. There are viscous substances, and after the abrasive flow processing is completed, a layer of lubricating substances will be left on the surface of the workpiece, which is not allowed for many workpieces

Moreover, the price of abrasives is high, so the processing cost is relatively high. For relatively fragile thin-walled parts, since abrasive flow processing is processed by using the pressure applied to both ends of the fixture, such fragile parts are not suitable for using abrasive flow. Method processing

Through ultrasonic rolling workpiece, the roughness can be reduced and the processing accuracy can be improved. However, traditional ultrasonic rolling processing devices are mostly installed on lathes or milling machines, and are mostly used for processing the outer surface or end face of the workpiece. The surface quality of the inner hole is processed by traditional surface processing technology. Difficult to meet
