Ultrasonic micro grinding and processing equipment and technology thereof

Abstract

The invention discloses ultrasonic micro grinding and processing equipment and a technology thereof. The equipment comprises a vibration isolation operating table, wherein columns which are in left-right symmetric arrangement are fixed on the vibration isolation operating table, the columns are connected via a beam, a main shaft component which drives a grinding device to rotate at a high speed is arranged on the beam, an ultrasonic vibration platform is arranged below the main shaft component, and the ultrasonic vibration platform is a two-dimensional ultrasonic vibration platform which is driven by a piezoelectric stack actuator and takes a polar coordinate system as an operating coordinate system. According to the single-drive polar coordinate two-dimensional ultrasonic micro grinding and processing equipment, provided by the invention, during processing, the piezoelectric stack actuator is selected for replacing the existing common ultrasonic amplitude transformer as a driving source, amplitude and frequency can be adjusted, and at the same time, the structure of the ultrasonic vibration platform is greatly simplified; besides, multiple grinding modes, such as dry grinding, wet grinding, peripheral grinding, face grinding and the like, are provided, and processing effects are better; after the ultrasonic micro grinding and processing equipment is used for processing workpieces, the processing is simpler and more diversified, and the precision of processed workpieces is higher.

Description

technical field [0001] The invention relates to the technical field of special processing, and more specifically relates to an ultrasonic grinding processing equipment and process. Background technique [0002] Special processing refers to processing methods that do not belong to the category of traditional processing technology. It is different from traditional processing methods that directly use mechanical energy to remove excess materials such as props and abrasive tools. It generally refers to the use of electrical energy, thermal energy, light energy, chemical energy, and electrochemical energy. , sound energy, special mechanical energy and other energy to achieve the removal or increase of material processing methods, so that the material can be removed, deformed, changed in performance or plated, etc. Special processing is a new technology developed in recent decades. It is an important supplement and development to traditional processing methods. It is still being r...

Problems solved by technology

[0009] 2. The micro-grinding wheel is easy to wear and difficult to repair

[0010] Because the diameter of the grinding wheel used in micro-grinding is very small, the micro-grinding wheel is very easy to wear, and the micro-grinding wheel is difficult to trim, which reduces the service life of the micro-grinding wheel, seriously affects the efficiency of micro-grinding, and restricts the further development of micro-grinding technology ;

[0011] 3. The research on ultrasonic vibration grinding mechanism and scale parts processing equipment is not perfect

[0012] Ultrasonic vibration-assisted machining has been widely used in turning, drilling, filing, etc. However, due to the complexity of the grinding process, the research on ultrasonic vibration-assisted grinding (especially the research on the processing mechanism) at home and abroad is not deep enough. , the research work on the design of ultrasonic vibration-assisted grinding processing platform is still very little, especially the design of simple and practical two-dimensional ultrasonic vibration platform is even rarer.
