Description
Technical field
The invention belongs to ultrasonic vibrating machining engineering device technique fields, and in particular to a kind of accessories type rotary ultrasonic vibrating blade
Handle.
Background technique
With the development of modern science and technology and production, the especially development of aerospace field technology, the use condition of material
It is more and more harsher, it is also higher and higher to the performance requirement of material.To meet the needs of hi-tech development, it is new to there is high-performance
Profile material, such as hard brittle material, composite material, high temperature alloy, titanium alloy have the advanced material of outstanding properties.Hard brittle material
(such as artificial lens, engineering ceramics, optical glass) have high rigidity, high temperature resistant, wear-resistant, chemical stability is good, is not easy oxygen
The advantages that changing, is corrosion-resistant, is widely used in the fields such as Aeronautics and Astronautics, military project, electronics and automobile.Composite material has superior
Physical property, chemical property and mechanical performance, for example, high specific strength, high specific stiffness, high ratio modulus, it is good insulation, it is heat-insulated, every
Sound performance has other performances such as enough fracture toughnesses and media-resistant corrosion, in Aeronautics and Astronautics, guided missile, electronics, automobile and life
The fields such as object engineering just have been more and more widely used, and constantly extend to new field.
Currently, the manufacture for hard brittle material part, the mode for generalling use grinding is processed.But since its is higher
Hardness and brittleness cause its cutting ability poor, are also easy to produce when carrying out the removal of material to it with traditional processing method larger
Grinding force and grinding heat, it is serious to make so as to cause workpiece fragmentation, surface/sub-surface damage and the service life etc. for reducing cutter
The about development and application of hard brittle material.Mostly use the processing side of traditional high-speed numeric control milling greatly for the processing of composite material
Method, this processing method are the material cut off will to be needed to smash with milling cutter, can generate a large amount of dust, cause environmental pollution, directly
Jeopardize the physical condition of worker.In addition, the piece surface of processing will appear burr, layering, spike protein gene etc., influence to add
Working medium amount and efficiency.
Ultrasonic wave processing is suitable for the processing to a variety of hard brittle materials and composite material, particularly suitable for non-conductive or resistance is processed
Rate is high and cannot use the hard brittle materia of electrical discharge machining；The machining tool of ultrasonic wave processing does not need to rotate, workpiece
There is no complicated relative motion between tool, therefore machining tool can be used softer material and be made into complicated shape, be easy to
Realize the molding hole of various complicated shapes and the processing of molded surface.Since the material removal in ultrasonic wave processing is by minimum mill
Material part, instantaneous effect of impact, therefore the cutting force of workpiece surface and cutting heat very little will not cause to deform and burn, can
To obtain higher machined surface quality, machining accuracy and processing efficiency.
Ultrasonic machining is to make the tool of small amplitude motion using supersonic frequency, and be free in liquid between workpiece by it
Abrasive material the knocking of surface to be machined is acted on, the special process method for being crushed workpiece material surface gradually.Wherein, ultrasonic sound
System is mainly made of energy converter, amplitude transformer, cutter.Power supply is converted into supersonic frequency electric oscillation signal by supersonic generator,
Electric oscillation signal is converted into supersonic frequency mechanical oscillation by energy converter, and amplitude transformer amplifies the vibration amplitude of energy converter, luffing
Bar connects cutter, processes vibration cutting.
In existing ultrasound knife handle integrated morphology, ultrasonic assembly is installed on inside knife handle, ultrasonic assembly and knife handle when work
It rotates together with, to need for ultrasonic current signal to be introduced from outside into the component of rotation.Generally use carbon brush or conducting slip ring group
To realize the current signal transmission of sound component.But this design keeps ultrasonic knife handle integrated morphology complicated clumsy, is not easy automatic
Tool changing.For example, application No. is the patent documents of CN201410637206.5 to disclose " a kind of improvement electro spindle ", Rotor terminal is logical
Brush transmitting ultrasonic signal is crossed, via central spindle, ultrasonic transducer is integrated in internal rotor, separate type amplitude transformer is connected by pulling claw
It is connected to spindle rotor.But the problems such as patent is not assembled in view of actual transducer in practice, changes main shaft internal structure
Larger, enforcement difficulty is also relatively high when tool changing.Also there is ultrasonic knife handle integrated morphology super using the transmission of contactless conductive component
Acoustoelectric current signal, such as discloses that " non-contact energy transmission formula ultrasound adds application No. is the patent document of CN201410212162.1
Tooling is set ", using former and deputy side magnetic ring coil electromagnetic induction, realize the non-contact transmission of ultrasonic signal, but amplitude transformer and transducing
Device segmentation connection will lead to vibration transmitting loss it is larger, transmission high-power signal can not be stablized.
