Dynamic high-performance process component.
The technical solution adopted in the present invention is:A kind of inverted turning electro spindle, main shaft tail diameter is small upward, main shaft
Stood upside down down greatly with short circular conical surface, diameter on head.Upper three supports main shaft in lower, lower middle support is fixed support, with 4 two groups
The paired back-to-back configuration increase main shaft support span of main shaft bearing, bears radial-axial bidirectional force, rear support is float support, only
Bear radial load.Increase support span again with inside and outside two kinds of spacers between two groups of bearings in lower, with the length difference of interior outer separator
It is worth 4 main shaft bearings of pretension.Middle spring bearing inner ring is locked by the positioning of spindle shaft rank, round nut under main shaft;Middle support under main shaft
Bearing outer ring is positioned by main tapping sets of holes bottom face, bearing labyrinth caping is tight;Upper support cylindrical roller bearing, short cylindrical rolling
Sub- bearing inner race with spindle shaft rank and spacer axially position, bearing holder (housing, cover) top, tension ring push-tight it is locked.Electro spindle rotor assembly by
It is interference fitted between spindle shaft rank axially position, rotor assembly endoporus and main shaft external cylindrical surface;The stator module of electro spindle is cylindrical
Closed helical annular cooling bath is cooperatively formed between cylinder and headstock bore inwall, circulation flows into cooling fluid control temperature rise.It is main
Shaft head be fixed with rotated together with main shaft get rid of dirty lid, get rid of it is dirty cover actionless labyrinth bush, labyrinth bush is fixed on axle
On the lower surface for holding labyrinth lid, bearing labyrinth lid is fixed on actionless main shaft headgear lower surface, and seam is withstood under main shaft
Spring bearing outer ring, get rid of and form multiple labyrinth group between dirty lid, labyrinth bush, bearing labyrinth lid and main shaft, prevent extraneous dirty dirt from entering
Enter main shaft bearing, prevent main shaft bearing lubricant grease from outflowing;The bearing cap cavity of spring bearing inner ring upper surface in push-tight main shaft
The projection of collar bush upper surface is covered, prevents foreign matter from falling into bearing;The closed cavity of the formation such as electro spindle stator, rotor and the external world
Between air with functions such as dust-proof, noise reductions balanced valve balance cavity pressure, temperature, prevent from running at high speed to be formed negative pressure,
Influence electro spindle performance;What orientation trouble standard was stopped transmits block and holds out against the bearing holder (housing, cover) of main shaft rear support cylindrical roller bearing inner ring
Integrated by balancing frame, balancing frame is also the dynamically balanced adjustment disk of spindle assemblies.
The beneficial effects of the invention are as follows:Turning main shaft stands upside down, and hangs sky clamping workpiece, workpiece hole mouth down, aperture knife tool
The workpieces processing below workpiece, cutter chip removal cleaning effect is good, coordinates along with big flow cools down cleaning system, iron filings are to processing
Interference and influence be possible to be reduced to minimum, the left over by history that compensate for conventional master spindle along vertical machine tool chip removal difference is asked
Topic, laid a good foundation for automatic reliable processing continuous for a long time;Turning main shaft handstand lathe coordinates with turning main shaft along vertical lathe
Use, workpiece u-turn clamping process and corresponding special carrying tooling can be saved;A kind of new machine has been derived from, has been machine industry
A kind of new research field is opened, there is certain scientific research value.
