Abstract

The invention discloses a two-dimensional ultrasonic vibration auxiliary grinding device used for grinding large structural parts. An upper panel and a lower panel are supported and fixed by a landing leg; the two ends of the upper panel are provided with an adjustable pressure pad and a pressure pad; a longitudinal amplitude transformer is fixedly connected with a longitudinal transducer; a coaxial amplitude transformer is fixedly connected with a coaxial transducer; the longitudinal end of the upper panel is fixedly connected with the longitudinal amplitude transformer; the coaxial end of the upper panel is fixedly connected with the coaxial amplitude transformer; the longitudinal transducer is connected with a first ultrasonic generator; the coaxial amplitude transformer is connected with a second ultrasonic generator; the output line of the first ultrasonic generator is connected with a first cymometer; the output line of the second ultrasonic generator is connected with a second cymometer; a processing grinding wheel is arranged on the upper part of the upper panel, thus solving a series of difficulties like low processing efficiency, poor surface quality and high processing cost of a structural ceramic material and realizing the precise processing of a large ceramic flat with high efficiency and quality.

Description

Technical field: [0001] The invention is suitable for the precision machining of difficult-to-machine materials, especially the precision machining of large structural parts of hard and brittle materials such as ceramics. Background technique: [0002] Due to high hardness and high brittleness, engineering ceramic materials are difficult to form and process, and traditional processing methods are difficult to achieve the desired effect. At present, diamond grinding wheel grinding, laser processing and ultrasonic machining are commonly used, but when using diamond grinding wheel for grinding, the grinding ratio is small, the production efficiency is low, and the diamond consumption is large, which makes the processing cost too high, accounting for about 10% of the total parts. 50% to 70% of the cost; at the same time, the fracture toughness of ceramic parts processed by diamond grinding wheel is highly dispersed, the reliability is unstable, the strength is reduced, and the f...
