Abstract:
1. A spindle of an ultrasonic machine for transmitting vibration to a working tool of the ultrasonic machine, comprising: a main body; a rotor disposed inside the main body; an elastic clamping unit disposed inside the rotor, wherein the elastic clamping unit comprises a clamping element for clamping the working tool and a flexible hinge contacting the clamping element; a vibrating unit for providing the elastic clamping unit with vibration against the rotor, wherein one end of the vibrating unit is connected to an inner wall of the rotor and the other end of the vibrating unit is connected to the flexible hinge; and a pre-pressure unit penetrating the rotor, wherein one end of the pre-pressure unit is connected to the flexible hinge, allowing the pre-pressure unit to be used for providing the elastic clamping unit with rigidity against the rotor such that the elastic clamping unit can provide pre-pressure to the vibrating unit.
