Problems solved by technology

However, the traditional sawing is only carried out on a specific sawing machine, and the addition of ultrasonic-assisted sawing is even more limited. Although many achievements have been made in related fields at home and abroad, there is still no one that can be used for multiple applications. The quick-change ultrasonic vibration sawing tool used in this kind of machine tool will limit the practical range and flexibility of sawing process
[0004] In ultrasonic processing, ultrasonic assisted sawing has been studied, but there are still defects: for example, in the Chinese patent No. 96195671.2, the symmetrical horn method is mainly used to obtain the ultrasonic vibration of the saw blade at the antinode point.
This method is to assemble and connect the saw blade with the horn and the main shaft on a specific sawing machine. When the saw blade is worn or damaged, the quick change of the ultrasonic tool cannot be realized, and the interchangeability is relatively poor, resulting in Medium flexibility is poor
For example, in Chinese Patent Nos. 201110060716.7 and 200920314714.4, the overall connection mode of the standard tool bar of a specific machine tool is used in the connection mode between the ultrasonic tool and the spindle, which limits the ultrasonic tool to only be processed on the supporting machine tool, greatly reducing the ultrasonic tool. Practical range of machine tools. At the same time, when there is a problem with the ultrasonic tool, it is not conducive to replacing the ultrasonic vibration device, which limits its flexible manufacturing performance
[0005] At present, the existing ultrasonic vibration assisted sawing device mainly has complex structure, integration, very difficult maintenance and assembly, low interchangeability, and high processing cost, so it has not been widely used in actual production.

Abstract

The invention discloses a quick-change ultrasonic vibration auxiliary sawing device which is suitable for various machine tools. The quick-change ultrasonic vibration auxiliary sawing device comprises a knife handle connecting bar (13), an inner sleeve (15), an outer sleeve (25), an ultrasonic transducer (19), a current collecting device, a primary amplification amplitude-change pole (31), a symmetrical amplitude-change pole (2) and a saw blade (1). According to the quick-change ultrasonic vibration auxiliary sawing device, high-frequency signals are generated through an ultrasonic generator and transmitted to the ultrasonic transducer (19) through the current collecting device to generate ultrasonic vibration, the ultrasonic vibration is amplified through the primary amplification amplitude-change pole (31), the amplified ultrasonic vibration is transmitted to the wave loop position of the symmetrical amplitude-change pole (2) to generate radial vibration, and the radial vibration acts on the saw blade. The quick-change ultrasonic vibration auxiliary sawing device can be flexibly butted with various machine tools, so that the processing application of the traditional machine tool is expanded; the quick-change ultrasonic vibration auxiliary sawing device realizes to use the ultrasonic vibration to assist in sawing hard and brittle materials, solves the problems of big sawing force, high material consumption, and serious edge breakage and so on of the traditional hard and brittle material sawing, and has broad application prospect.

Description

technical field [0001] The invention relates to a sawing processing device in the field of precision machining of hard and brittle materials, in particular to a quick-change ultrasonic vibration-assisted sawing device for various machine tools. Background technique [0002] The application of high-performance hard and brittle materials such as optical glass, crystal and ceramics is limited by their high hardness and high brittleness, so it is difficult to process the required shape and precision requirements of the application parts. With the increasing level of machining, these materials Applications are increasingly expanded. Usually, in the preparation and processing of these hard and brittle material parts, sawing is the first process of mechanical processing, which has a very important impact on the processing cost and quality of parts. At present, it is the most common process to process hard and brittle materials by using the superior hardness of diamond as saw blade...
