The invention belongs to the technical field of composite ultrasonic milling, and discloses an intelligent longitudinal twisting composite ultrasonic milling device. The device comprises a flange plate, a longitudinal twisting amplitude change rod and a tool bit coaxially arranged, and piezoelectric ceramic sheet sets arranged on two end surfaces of the flange plate, wherein each piezoelectric ceramic sheet set comprises two piezoelectric ceramic sheets; an electrode sheet is arranged between the two piezoelectric ceramic sheets; insulation pieces are arranged on two end surfaces of the piezoelectric ceramic sheet sets; the longitudinal twisting amplitude change rod is arranged at the lower side of the piezoelectric ceramic sheet set on one side; the tool bit is arranged at the lower end of the longitudinal twisting amplitude change rod; and the longitudinal twisting amplitude change rod is provided with a spiral groove for converting single longitudinal vibration to longitudinal twisting same-frequency composite vibration. The device realizes longitudinal twisting composite ultrasonic milling, can achieve intelligent feedback control all the time, is simple in structure and convenient to install, can replace multiple cutters, and realizes ultraprecise machining on multiple hard and brittle materials.
Description
technical field [0001] The invention relates to a compound ultrasonic milling processing technology, in particular to an intelligent longitudinal-torsion compound ultrasonic milling device. 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 process...
