Description

Technical Field

[0001] The invention relates to the technical field of hard and brittle material processing, and in particular to a single-excitation two-dimensional ultrasonic elliptical vibration processing platform device and a use method thereof. Background Art

[0002] Hard and brittle materials such as ceramics, single crystal silicon, and microcrystalline glass have excellent mechanical properties such as high strength, high hardness, wear resistance, high temperature resistance, chemical corrosion resistance, oxidation resistance, and toughening modification. With the development of science and technology and industry, the manufacturing industry is developing towards high-performance materials and precision manufacturing. On the one hand, the demand for hard and brittle materials with excellent physical, chemical and mechanical properties is increasing, and on the other hand, higher requirements are put forward for the processing accuracy, processing quality and processing efficiency of key parts. Hard and brittle materials such as ceramics, single crystal silicon, and microcrystalline glass are increasingly used in optoelectronics, aerospace, automobiles, biomedical engineering, 3C digital and other fields. However, due to the limitations of its own process level, traditional processing technology is prone to generate large cutting forces and cutting temperatures when processing hard and brittle materials, resulting in problems such as substandard surface quality of key parts, poor surface accuracy, low processing efficiency, and low tool life. Therefore, it is necessary to continuously explore new ultra-precision processing technologies, methods, and processes to meet the increasingly urgent requirements of the advanced manufacturing and processing industry.

[0003] Ultrasonic elliptical vibration machining technology was first proposed by Japanese scholar Eiji Shamoto at the CIRP International Conference. He combined ultrasonic elliptical vibration with traditional ultrasonic machining, changing the removal mechanism of traditional cutting machining. During the elliptical vibration cutting process, the tool intermittently contacts and separates from the workpiece and chips, which not only helps to reduce the cutting force, but also helps the outflow of chips. Compared with ordinary cutting and one-dimensional ultrasonic vibration cutting, ultrasonic elliptical vibration cutting has many advantages such as reducing cutting force, reducing cutting temperature, reducing tool wear, inhibiting burr generation, reducing built-up edge, inhibiting chatter, improving cutting stability, reducing surface roughness, improving machining accuracy, and increasing tool life.

[0004] Many scholars have studied ultrasonic elliptical vibration machining. These research results are of great significance to the use of ultrasonic elliptical vibration in improving the machining quality of difficult-to-machine materials and extending tool life. However, there are still some gaps in the study of ultrasonic elliptical vibration, mainly manifested in the following aspects: (1) Previous studies on ultrasonic elliptical vibration milling and grinding were mostly about modifying the spindle or tool holder, which would lead to reduced machine tool accuracy and rigidity. (2) In the past, the design of ultrasonic elliptical vibration platforms mostly used a dual excitation method to achieve a composite of two vibrations, and there was almost no research on the use of a single excitation method to design an ultrasonic elliptical vibration platform.

[0005] In the design of dual-excitation vibration platforms, two groups of piezoelectric ceramic stacks are mostly used. The ultrasonic elliptical vibration is generated by combining two vibration modes of longitudinal vibration, torsional vibration, bending vibration and radial vibration. The design of two groups of piezoelectric ceramic stacks will increase the volume and complicate the structure of the entire ultrasonic elliptical vibration platform. In addition, two ultrasonic power supply signals are required for excitation, which increases the difficulty of ultrasonic power supply design. Summary of the invention
