Technical field
The utility model relates to ultrasonic edm Combined Machining Technology field, particularly relates to a kind of ultrasonic edm Compound Machining oscillator based on longitudinal vibration mode.
Background technology
In using spark-erosion machine tool processing micro hole process, because the aperture is trickle and discharging gap is narrow and small, causes the galvanic corrosion thing to accumulate at the bottom of the hole, the chip removal difficulty, stable discharging gap scope is little and be subjected to the influence of other technological parameter easily, easily causes short circuit frequently and improper discharge.Also have the capillary processing tool-electrode trickle, when aspect ratio was big, paradoxical discharge easily burnt tool-electrode, cause processing not stablize and carry out, but the range of work narrow down, make traditional electric machining in minute aperture processing, can not become effective processing method.
Therefore, for improving the spark machined performance, adopting the ultrasonic edm Compound Machining in minute aperture processing is very effective means.Attached supersonic vibration on electrode or workpiece just can make electrode end surface frequently enter suitable discharging gap, improves the probability that electric spark punctures; Owing to ultrasonic cavitation and pump-absorb action, can increase the clearance of machined material simultaneously.Accelerate working cycles, improve the gap discharge condition, thereby improve aspect ratio, processing stability, the productivity ratio in processed hole, utilization rate and the machining accuracy of power pulse;
The common method of ultrasonic edm Compound Machining is the ultrasonic vibration at the additional certain frequency of tool-electrode, utilize the swabbing action of tool-electrode to improve the spark machined condition, but since electrode when very fine its rigidity less, also can oscillation crosswise when doing ultrasonic vibration up and down, be difficult to guarantee the radially machining accuracy of minute aperture.In addition, when the transducer of the additional generation of tool-electrode ultrasonic vibration, need carry out bigger change to electrode structure and control system thereof, thereby make structure become more complicated.
Summary of the invention
The technical problem that the utility model mainly solves provides a kind of ultrasonic edm Compound Machining oscillator based on longitudinal vibration mode, it has simplified project organization, can clamp and dismantle workpiece easily, electrode structure and the control system thereof of existing lathe are not being carried out under the condition of bigger change, attached supersonic vibration easily on existing spark-erosion machine tool improves the radially machining accuracy of minute aperture.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of ultrasonic edm Compound Machining oscillator based on longitudinal vibration mode is provided, should comprise ultrasound transducer means and the workpiece clamping mechanism that is rigidly connected based on the ultrasonic edm Compound Machining oscillator of longitudinal vibration mode, described ultrasound transducer means comprises that balancing weight A, balancing weight B, electrode slice, piezoelectric ceramics, terminal pad and the cone back that superposes successively links together the cone front end workpiece clamping mechanism that is being rigidly connected by bolt;
