JUNCTION STRUCTURE OF MOTHER HORN AND CHILD HORN IN CUTTING RESONATOR OF ULTRASONIC CUTTING DEVICE

摘要

PROBLEM TO BE SOLVED: To apply sufficient tension to a cutting wire or blade body stretched between the tips of a pair of child horns so as to correctly transmit vibration of the horns at the time of cutting.;SOLUTION: Stud bolts 7 consisting of material whose tensile elastic modulus and flexural elastic modulus are low to a required degree compared to iron, and provided with flange-like protrusion parts 7A with cross-sectional areas smaller than the cross-sectional areas of joint surfaces 3A, 4A of child horns 3, 4 with a mother horn 2 on the central part in the axial direction are used. Both side screw parts 7a, 7b of the stud bolts 7 are respectively screwed into screw holes 2a, 2a provided on the joint surface of the mother horn 2 with the pair of child horns 3, 4 and screw holes 3a, 4a provided on the joint surface of the pair of child horns 3, 4 with the mother horn 2 to integrally join the mother horn 2 and the pair of child horns 3, 4.;COPYRIGHT: (C)2016,JPO&INPIT
