Processing gap only have a few micrometers to some tens of pm, the flowing realizing electrolyte in such narrow space is by no means easy.But
By suitable technological means, allow electrolyte " move " within the specific limits and get up and can realize.
Supersonic vibration is put in electrochemical machining process by ultrasonic disturbance electrolyte electrochemical micromachining exactly, makes electrolyte
Produce high frequency components." cavitation " effect of ultrasound wave can change the ablation mechanism of electrochemical micromachining product, and electrolyte is high simultaneously
Frequently CURRENT DISTRIBUTION, the electrolytic conductivity regularity of distribution in processing gap, and then impact processing gap can also be affected in the case of disturbance
Distribution.Preliminary analysis proves, uses the method for ultrasonic wave added to maximize favourable factors and minimize unfavourable ones, the advantage of micro-electrochemical machining is brought into play, be
A kind of effective means improving dissolving locality.
Want to study ultrasonic disturbance electrolyte and Electrolyzed Processing is dissolved the impact of locality, first have to be capable of this adding
Work mode, the mode using ultrasonic disturbance here is that supersonic frequency vibration is directly acted on electrolyte.Ultrasonic generator produces
Ultrasound wave, is converted to supersonic frequency vibration through transducer, the most directly contacts the electrolyte of processing district, it is achieved electrolyte ultrasonic
Vibration.This kind of mode transmittance process is simple, and effect directly, can well reach the purpose of ultrasonic disturbance.Additionally, this mode is to adding
The design and use of work lathe do not have extra demand, and ultrasonic wave added device can design as a standalone module, installs and make
With, low cost, the suitability is good.But be intended to reach disturbance electrolyte, ultrasound wave plays purpose that " cavitation " act on must be by special
Fixture, allow workpiece can convenient mounting and clamping, the most disturbed electrolyte surrounds, really has influence on the course of processing.
Summary of the invention
It is an object of the invention to meet the needs of ultrasonic disturbance electrolyte processing, be designed to meet the folder of processing request
By fixture, tool, ensures that the disturbance of electrolyte is uniform, flow field is stable, pressure equalizes, and isolates external disturbance, clamping workpiece is reliable,
Negative electrode stablizes feeding in fixture, completes minute aperture Electrolyzed Processing in disturbance electrolyte processing district, reaches precision and surface matter
Amount requirement.
The fixture of a kind of ultrasonic disturbance electrolyte micropore Electrolyzed Processing, installs on fine electrolytic machining tool workbench, its
It is characterised by:
(1), there is the electrolysis zone of a cavity type at this jig main body center；
(2), jig main body also has a work holder, is cylinder porose in the middle of, points upper and lower two pieces, below one
Block is with base.Two pieces of relative two face flutings, install sealing gasket, use bolt fastening.
(3), work holder is designed as the sleeve of different-diameter, for the selection of different size machining area.
(4), upper and lower two of processing district, be respectively connected to ultrasonic vibration installation, the electrolyte of disturbance processing district under same frequency.
Minute aperture adds man-hour, and workpiece is arranged on work holder, forms upper and lower two cavitys, adds fully charged solution in man-hour
Liquid, the supersonic vibration that Vltrasonic device sends is delivered to the electrolyte of the two processing district.Electrolyte in whole electrolytic bath is mutual
Leading to is an entirety, can update with convection current man-hour adding.
