Ultrasonic cutter handle

Abstract

The invention discloses an ultrasonic cutter handle which comprises a blind rivet, a cutter handle, a flange plate and an ultrasonic milling device. The front end of the cutter handle is detachably connected with the blind rivet; the flange plate adopts a symmetric design and is fixedly connected with the tail end of the cutter handle; the ultrasonic milling device comprises a first piezoelectricceramic assembly, a second piezoelectric ceramic assembly, a third piezoelectric ceramic assembly, a fourth piezoelectric ceramic assembly, an amplitude-change pole and a chuck; the first piezoelectric ceramic assembly and the second piezoelectric ceramic assembly are symmetrical with respect to the flange plate; the amplitude-change pole comprises a cylindrical section and a conical section; oneend of the cylindrical section supports the third piezoelectric ceramic assembly and the fourth piezoelectric ceramic assembly; the other end of the cylindrical section is fixedly connected with the bottom end of the conical section; and a circle of spiral groove is uniformly formed in the surface of the cylindrical section. The flange plate with the symmetric design is adopted, and one circle ofspiral groove is arranged on the cylindrical section of the amplitude-change pole, so that longitudinal and torsional two-dimensional ultrasonic vibration can be output at the same time; and in addition, longitudinal and torsional nodes coincide in positions on the flange plate, so that the excitation frequency of the ultrasonic milling device and the ultrasonic wave transmission efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of milling, and in particular relates to an ultrasonic tool holder. Background technique [0002] With the continuous improvement of modern technology and industry's requirements for materials, especially in the fields of aerospace, chemical industry, military, machinery, electronic appliances and precision manufacturing, in addition to some special properties, materials must also have excellent comprehensive properties. However, these materials often have processing difficulties such as high strength, high hardness, high brittleness and anisotropy, making it difficult for traditional milling processes to achieve efficient and high-quality milling. [0003] Compared with traditional mechanical processing, ultrasonic vibration cutting can not only reduce the cutting force and cutting heat effect, but also greatly reduce the surface roughness of the processed workpiece, improve the processing accuracy and prol...
