Abstract
An ultrasonic machining module that includes an ultrasonic transducer, wherein the ultrasonic transducer is adapted to receive a machining tool and a vibration-isolating housing adapted to be both compatible with a machining system and to receive the ultrasonic transducer therein, wherein the housing further includes at least one modification for isolating all vibrations generated by the ultrasonic transducer when the device is in operation except axial vibrations transmitted to the machining tool, thereby preventing unwanted vibrations from traveling backward or upward into the machining system.
Claims36
1) A device for use in a machining system, comprising:
- (a) an ultrasonic transducer having a known nodal position, wherein the ultrasonic transducer is adapted to receive a machining tool, and
- (b) a vibration-isolating housing adapted to be both compatible with a machining system and to receive the ultrasonic transducer therein, wherein the housing further includes at least one modification for isolating all vibrations generated by the ultrasonic transducer when the device is in operation except axial vibrations transmitted to the machining tool, thereby preventing unwanted vibration from traveling backward or upward into the machining system.
14) A device for use in a machining system, comprising:
- (a) an ultrasonic transducer having a known nodal position, wherein the ultrasonic transducer is adapted to receive a machining tool;
- (b) a vibration-isolating housing adapted to be both compatible with a machining system and to receive the ultrasonic transducer therein, wherein the housing further includes at least one modification for isolating all vibrations generated by the ultrasonic transducer when the device is in operation except axial vibrations transmitted to the machining tool, thereby preventing unwanted vibrations from traveling backward or upward into the machining system;
- and
- (c) a tool holder, wherein the tool holder and the top portion of the housing are mechanically coupled to one another or are integrated with one another.
26) A device for use in a machining system, comprising:
- (a) an ultrasonic transducer having a known nodal position, wherein the ultrasonic transducer is adapted to receive a machining tool;
- (b) a vibration-isolating housing adapted to be both compatible with a machining system and to receive the ultrasonic transducer therein, wherein the housing further includes at least one modification for isolating all vibrations generated by the ultrasonic transducer when the device is in operation except axial vibrations transmitted to the machining tool, thereby preventing unwanted vibration from traveling backward or upward into the machining system;
- (c) a tool holder, wherein the tool holder and the top portion of the housing are mechanically coupled to one another or are integrated with one another;
- and
- (d) an internal sealing system, wherein the internal sealing system includes:
- (i) a conical alignment boss formed in the transducer at the nodal point thereof;
- (ii) a conical flange formed in the housing, wherein the conical flange is stretched within its elastic limits over the conical alignment boss thereby sealing the housing against a horizontal base formed on the transducer;
- and
- (iii) a groove formed in the horizontal base on the transducer for receiving an O-ring, wherein the O-ring provides additional sealing properties to the device.
