Description
[technical field]
The present invention relates to ultrasonic cutter field more particularly to it is a kind of for ultrasonic knife handle for electro spindle.It can be via
Ontology is generated the hilt for being electrically connected circuit for electro spindle by ultrasonic knife.
[background technique]
Oscillator, such as the high-frequency vibration of piezoelectric patches mainly are utilized by the ultrasonic wave transmission main shaft of processing machine, so that dress
The higher-order of oscillation can be generated set on transmission main shaft cutter, allows cutter that can be effectively reduced cutting resistance, so as to by workpiece to be processed table
The particle in face separates one by one.When workpiece to be processed is not only hard but also crisp material, such as when glass, ceramics, zirconium dioxide ..., if
Can be processed with ultrasonic wave transmission main shaft, can not only make to process caused by clast become more thin thin, while can extend
Cutter life.
Furthermore when ultrasonic wave transmission main shaft carry out high-frequency vibration processing when, cutter because vibration source addition, so cutter with
When workpiece to be processed contacts, cutter increases axial high-frequency vibration in addition to main shaft rotation is outer, so that cutter is under twofold motion,
Promote the material removal of workpiece to be processed.Therefore, ultrasonic wave transmission main shaft have mitigate processing resistance, improve processing efficiency,
Improve the processing surface roughness of workpiece to be processed, cutter itself because of vibration non-sticky glutinous cutting detritus, tool life
The advantages of, so ultrasonic wave transmission main shaft is widely used by industrial circle at present.
As shown in TaiWan, China patent announcement M534047 Patent Case its " the electrical live spindle structure of self-cleaning ",
Including a main shaft；One conductive sleeve group, is socketed on the main shaft, and has two conducting rings；One power supply set group, has a carbon brush
Ring seat and two carbon brush parts, the carbon brush ring seat are placed on outside the conductive sleeve group, and have gap, the carbon brush ring between the conductive sleeve group
The gas hole radially extended on seat circumferential surface with the two carbon brush accommodating holes radially extended and one, the grade carbon brush part respectively radially place
It in the equal carbon brush accommodating hole, and is contacted with one end with the respectively conducting ring, waits carbon brush part to import the electric power of outside by this
The gas of outside is incorporated in the grade carbon brush part and the conductive interannular of the grade to the equal conducting rings, and by the gas hole.
Due to known elastic carbon brush part technological means system with elastic component provide elastic force pushing and pressing respectively the carbon brush part to the main shaft
Direction is mobile, if the elastic force of pushing and pressing opposite can also improve when the decrement of the elastic component is excessive, in turn results in the grade carbon brush
The abrasion of part is more serious；Conversely, if because the elastic force of pushing and pressing is insufficient, and then leading to this when the decrement of the elastic component is too small
Equal carbon brush part can not contact conducting ring, or even generate the probability of open circuit, not an effective solution scheme.
Therefore, how to provide the piezoelectric patches of ultrasonic wave transmission main shaft stable power supply supply, be that related dealer urgently overcomes
Problem.
