Equipped with slide plate 6, servomotor 8 drives slide plate 6 to move up and down along longitudinal rail 5 by screw-nut body, and main shaft 7 is arranged on cunning
On plate 6；Chuck 10 for clamping workpiece is provided with workbench 9, and workbench 9 is fixed on base 1 and is positioned at three root post 2 institutes
The center position of the equilateral triangle surrounded；The upper end of described main shaft 7 is provided with and it can be made to produce low frequency revolution exciting
Swing arm 12, swing arm 12 is made forward and reverse swing so that main shaft 7 produces circumference by being arranged on auxiliary vibration device 11 driving on column 2
Controlled low-frequency vibration.
Described column 2 is 70-80 degree with the angle of base 1.
Being mounted on identical auxiliary vibration device 11 on three described root posts 2, each auxiliary vibration device 11 is all provided with
Having two identical cam mechanisms, each cam mechanism is connected with the swing arm 12 on main shaft by respective connecting rod, three auxiliary
Three torsional oscillations that vibrating device 11 produces act on elimination eccentric torque jointly, thus improve the stability of lathe.
Described three root posts 2, base 1 and crossbeam 3 are connected to form integral vertical type structure.
Described column 2 uses the foundry goods (nodular cast iron or casting pig) of casting, and crossbeam 3 uses honeycomb sheet steel (Q
Series structure steel).
Described crossbeam 3 is fixedly linked with column 2 upper end by countersunk head self threading pin.
Beneficial effects of the present invention:
The tilted-putted three triangle structures of root post of the present invention, can improve lathe integral rigidity, particularly work as processing
During when applying ancillary vibration (torsional oscillation), on the one hand be distributed on many root posts due to auxiliary vibration device, can balance single
The eccentric torque that torsional oscillation produces, thus ensure machine stability；On the other hand, relative to single column and double pillar construction, three stand
When rod structure can effectively prevent from applying torsional oscillation, list column and double column are deformed, and cause torsional oscillation cannot effectively be delivered to main shaft
On；Additionally, three auxiliary vibration devices are distributed on three root posts, with frequency collaborative work, swing arm can be applied sufficiently large torsion
Square, fully meets the processing requirement to moment of torsion.
The auxiliary vibration device simple in construction of the present invention, applies mode reliable, frequency and adjustable amplitude.
