Description
Technical field
The present invention relates to annular magnet magnetic supporting rotary ultrasonic Knife handle structure.
Background technology
The hard brittle materials such as engineering ceramics, optical glass, artificial intraocular lenses are because having hardness height, chemical stability
The advantage such as good, the most oxidizable, wear-resistant, corrosion-resistant and be widely used.But, these hard brittle materials
Having high hardness and fragility, its processing is the most difficult.Ultrasound wave processing be recent decades progressively develop and
The novel processing method of one of application, substantial amounts of theoretical and experimental study shows, at hard fragility difficult-to-machine material
Precision Machining in ultrasound wave processing there is the technological effect that common processing methods is incomparable.In order to preferably
Play the advantage of ultrasound wave processing, generally by ultrasound wave processing and other tradition processing connected applications, as ultrasonic
Vibration-assisted grinding, supersonic vibration assisted machining, supersonic vibration auxiliary milling and supersonic vibration auxiliary drilling etc.,
In the processing that these are traditional, add supersonic vibration auxiliary energy be greatly improved its machining accuracy and working (machining) efficiency.
Rotary ultrasonic machining is a kind of combined machining method Ultrasonic machining and traditional mechanical processing combined.
Adding instrument in man-hour while making the extensional vibration of the little amplitude of supersonic frequency, making high speed rotating around its axis again simultaneously.This
Sample i.e. overcomes the feature that Ultrasonic Machining Efficiency is relatively low, improves again the precision of traditional mechanical processing.In order to expand
The application of big rotary ultrasonic machining, by designed in conjunction to ultrasonic vibration system and handle of a knife go out ultrasonic handle of a knife.
This handle of a knife directly can be connected with machine tool chief axis and realize high speed rotary motion, and supersonic vibration is then by ultrasonic generator
Machining tool is driven to do longitudinal ultrasonic vibration by horn.Whole ultrasonic vibration system is then by horn
Zero amplitude position is fixed with handle of a knife shell, does high speed rotary motion under handle of a knife shell drives.The most designed
Ultrasonic handle of a knife in ultrasonic vibration system it is entered only by zero shift node in horn together with machining tool
Row is fixing, and bearing's axial width is less, and therefore, the radial rigidity causing this handle of a knife is little, machining tool
Low with the axiality of machine tool chief axis, and when handle of a knife does high speed rotary motion, vibrational system rear end and tool ends end
Certain rocking will be produced due to bias, have a strong impact on machining accuracy.In order to improve radially of the axis of rotation
Rigidity and stability, generally need to be fixed in the two of axle position and limit, but, supersonic vibration due to
The vibration of ultrasound wave can be there is vertically, when carrying out Under Ultrasonic Vibration moving axis radially clamping, it can be hindered axial
Vibration so that ultrasonic energy lose, cause vibrational system to generate heat simultaneously.Therefore, be the most all
In horn amplitude be zero location point ultrasonic system is fixed, poor stability, radial rigidity is low, makes
Obtain machining accuracy to reduce.
