Compound vibrating grinding wheel for ultrasonic processing

Abstract

The invention discloses a compound vibrating grinding wheel for ultrasonic processing. The compound vibrating grinding wheel is provided with inner and outer grinding rings which are connected througha connecting flange. Under the action of ultrasonic vibration, the inner and outer rings can vibrate ultrasonically simultaneously to exert the ultrasonic assisted grinding processing ability fully,so that the production efficiency can be improved. The shape and the mounting position of the connecting flange can be determined according to the modal of the outer grinding ring, so that friction ofthe connecting flange on a pitch circle and a pitch diameter is reduced; the inner side of the connecting flange is connected to a cone surface of the inner grinding ring, so that the transfer loss of ultrasonic sound among interfaces is reduced, the ultrasonic transfer efficiency is guaranteed, and the positioning precision is improved at the same time; the axial height of the inner grinding ring can be adjusted, and the end surface height difference of the inner and outer grinding rings can be changed by adjusting the axial height of the inner grinding ring, so that the grinding depth of the inner grinding ring is further controlled, and therefore, the production efficiency is improved by carrying out coarse processing and finish processing in a same step. The grooving forms of the inner and outer rings are changed to obtain ultrasonic vibration of different forms, so that different processing demands are met.

Description

technical field [0001] The invention relates to the field of ultrasonic machining, in particular to a composite vibrating grinding wheel for ultrasonic machining. Background technique [0002] With the development of aviation and aerospace industries, materials with high hardness and high brittleness such as ceramics and silicon carbide composite materials are more and more widely used. This type of material usually has excellent chemical and physical properties, and plays a good role in the manufacture of precision parts or harsh working environments. However, due to the hard and brittle characteristics of the material, it is difficult to process, the material is easily broken during processing, the temperature in the grinding area is high, and the tool wear is serious. Therefore, in order to ensure the processing quality and efficiency, a suitable processing method is needed to meet the production requirements. [0003] Ultrasonic assisted grinding technology is a new ty...
