Description
Technical field
The utility model relates to electric spark shaping mill, particularly the numerical control direct-drive type C axis mechanism of electric spark shaping mill.
Background technology
Electric Discharge Machining is to utilize electric spark ablation principle, adopts shaping jig electrode pair workpiece to discharge and duplicates processing.
In order to satisfy some comparatively processing request of complex-shaped surface mould, need on numerical control forming machine, increase by one around the rotating gyroaxis of the Z of vertical direction axle---C axle, finish the rotation calibration of part electrode, and can link simultaneously with X, Y, Z single shaft or multiaxis and synthesize different machining locus.
C axle on traditional electric spark shaping mill adopts direct current or AC servo machinery driving, but this class motor indexing accuracy is lower, moment of torsion is little during lower-speed state, add the poor stability in man-hour, so generally is to add to join a cover reducing gear (as gear pair, worm couple or harmonic speed reducer), promptly by direct current or AC servo motor outputting power through reducing gear deceleration rear drive C axle.There are factors such as gap, strain in this traditional scheme because of adopting mechanical reduction gear in the driving-chain, these factors all can have influence on precision, and entire mechanism makes that assembly precision requires that also high, complex structure, volume are big, Heavy Weight, cost are also higher.
Summary of the invention
The utility model purpose provides a kind of electric spark shaping mill numerical control direct-drive type C axis mechanism, has both improved precision, again simplified structure, reduce volume weight, reduce cost.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electric spark shaping mill numerical control direct-drive type C axis mechanism, fixedly install a motor mount at the Z of described electric spark shaping mill axle head, this motor mount is provided with and drives motor always, described direct driving motor has shell and rotating shaft, the relative motor mount of this shell is fixedly connected, and rotating shaft is that hollow shaft and gyratory directions are for to turn round around the Z axle; Be equipped with one in the hollow hole of described hollow shaft and advance electric axis, it is fixedly connected that this advances the relative hollow shaft insulation of electric axis; In described motor mount, be provided with a cavity, this upper end of advancing electric axis extends in the described cavity, the electric axis upper edge of advancing that is arranged in cavity is circumferentially with an annular contact surface, advance electric carbon brush to should annular contact surface being provided with one, this advances electric carbon brush insulating mounting on described motor mount, and the working face that advances electric carbon brush contacts cooperation with annular contact surface; The described lower end of advancing electric axis is provided with electrode holder.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the specific embodiments of described " it is fixedly connected that this advances the insulation of the relative hollow shaft of electric axis " has multiple, for example advance electric axis directly the key through being separated with insulating materials be connected with the hollow shaft hollow hole.But preferred version is as follows: describedly advance in the unsettled hollow hole that is arranged in hollow shaft of electric axis, the lower end of advancing electric axis is to stretch in the outer increase shaft shoulder portion of hollow shaft hollow hole, this increases shaft shoulder portion and fixedlys connected with the hollow shaft lower end through the insulation board isolation, constitutes the into fixedly connected structure of the relative hollow shaft insulation of electric axis with this; Fix described electrode holder in the described increase shaft shoulder portion.This scheme easily realizes.
2, in the such scheme, be fixed with dial on the periphery of described hollow shaft lower end, and correspondence is provided with cursor line on the shell of direct driving motor.So that indicate the precision indexing of C axle rotation in real time.
The utility model design principle and the effect of bringing: the utility model adopts direct driving motor, the cancellation reduction gearing mechanism, design the electric axis formula and advanced electric scheme, direct driving motor not only drives processing as precision indexing and rotating servo in this programme, and itself makes the maximum densification of structure, only tens of parts also as a connected body, very simple, be convenient to safeguard and install.The accurate angular contact bearing of two major diameters of direct driving motor inside can add required thrust in man-hour, pulling force and moment of torsion by sustaining electrode fully, and can keep high accuracy for a long time.In addition,, just not had drive gap and creeping phenomenon yet, made and transmit rigidity and obtain greatly increasing because of having save reduction gearing mechanism, the revolution repetitive positioning accuracy can reach ± and 1.3 seconds.
