Description
Technical field
The utility model belongs to the processing unit (plant) of the special process, is specifically related to a kind of high-speed electric main shaft general rotary ultrasonic transducer assembly.
Background technology
Since the mankind use first time gear friction produce 24KHz ultrasonic since, existing 108 more than ten years up to now.This is the ancient but also young progress of subject along with science and technology and the demand of related discipline not only, and its application technology throughout industrial and agricultural production, national defence, medical treatment, scientific research etc., can see her figure everywhere, the advantage of its irreplaceability sufficient proof it self.
Ultrasonic rotation processing is an important branch of applied acoustics, belong to the category of the special process, for cannot process by commonsense method or unmanageable material as: optical glass, pottery, YAG yttrium-aluminium-garnet, sapphire, synthetic quartz, jade, semi-conducting material (silicon, germanium), aluminium composite material, carbide alloy, permanent-magnet material, stainless steel, high temperature alloy etc., can realize the processing such as boring, grinding, milling type, engraving.
Rotary ultrasonic machining, i.e. composite ultraphonic ripple vibration on the cutter rotated, carries out rotary ultrasonic machining to workpiece.The ultrasonic wave abrasive machining that it is different from the past, its principle applies ultrasonic vibration on the cutter of original machining.Compared with processing with standard machinery, ultrasonic wave rotates Combined Machining Technology and has following characteristics:
1, the mechanical resistance of brill, mill, milling reduces greatly.Its reason is that after cutter applies ultrasonic vibration, workpiece and cutter will form high-frequency makes discontinuous contact, thus reduce mechanical resistance, also reduce heat in metal cutting simultaneously.Especially high at processing thermal coefficient of expansion, there is excellent performance during the uneven again material of material, not easily hot-spot occur and break or be out of shape.The surface to be machined of workpiece is smashed formation microscratch by ultrasonic wave vibration, and material can cut by cutter very easily.The reduction of cutting force not only makes production efficiency improve, simultaneously due to high-frequency makes discontinuous contact, also make cutter not easily locking twist off, wearing and tearing alleviate, and cutting-tool's used life is improved.
2, processing temperature is low, cooling and chip removal effective.Under ul-trasonic irradiation, cutter and workpiece are high-frequency makes discontinuous contact state, and cooling fluid can be ejected into workpiece and tool surface without dead band, not only forms the effect of ultrasonic cleaning, and flow rate of liquid is accelerated simultaneously, takes away rapidly heat and cooling effect is improved.Chip is evenly tiny powder or chip breaking, is easy to discharge, and prevents the generation of cut and crackle, substantially increases processing fineness.
3, reduce the mechanical force that workpiece applies, make cutter or workpiece not easily produce cutter relieving and flexural deformation, thus the precision in die cavity and hole, concentricity and cylindricity are improved.
Though there is above plurality of advantages, really also rare for the production of the high-speed ultrasonic electro spindle product in practice.Current known most technology also rest on collecting ring carbon brush structure or by electromagnetic induction on the basis of transducer power supply mode, under Same Efficieney, transducer volume is excessive, inefficiency can not high-speed cruising, the application of restriction technique on high-speed electric main shaft.The former contacts collecting ring to transducer feed by carbon brush, its shortcoming is that carbon brush easily weares and teares, the carbon dust come off easily makes collecting ring short circuit cause fault, when running up, carbon brush and collecting ring produce frictional heat simultaneously, rotating speed is made to be difficult to improve, periodic maintenance must clear up, change carbon brush, make troubles and extra charge to user.The latter's way of electromagnetic induction, although abandoned collecting ring and carbon brush, its efficiency of transmission is not high, harsh to the required distance between dynamic and static inductor during dynamic duty.Less stable when displacement and change of frequency, recognition capability be there is no to connection object, the transmitting energies such as easy peripherad metal such as shell, cause heating and energy loss, cause inefficiency.
Known transducer architecture in addition, does not have sonic reflection coating between its upper cover plate and piezoelectric element, piezoelectric element emission effciency under equal unit volume is low, and thus when piezoelectric element volume is too small, the radiable power of institute and conversion efficiency can not get improving.
