The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figs. 1-2, a kind of stack-press device for magnetic suspension bearing stator module, including rotation expansion core 1, expansion sleeve
2 and pedestal expansion core 3；2 upper and lower ends wall thickness of expansion sleeve is less than the intermediate wall thickness of expansion sleeve 2, and 2 inner surface upper and lower part of expansion sleeve is equal
Constitute the conical surface；The rotary shaft 4 being vertically arranged is equipped in rotation expansion core 1,4 bottom end of rotary shaft is equipped with and 3 screw top of pedestal expansion core
Hole be cooperatively connected external screw thread, 4 top of rotary shaft be equipped with die nut cooperation in six side's counterbores, 4 top of rotary shaft is higher than
Rotate 1 upper surface of expansion core；Rotating 1 outer surface of expansion core is the conical surface, rotation 1 outer surface of expansion core and the 2 inner surface top conical surface of expansion sleeve
Shape matches；3 outer surface of pedestal expansion core is the conical surface, 3 outer surface of pedestal expansion core and 2 inner surface lower tapered surface shape phase of expansion sleeve
Cooperation.
In the present invention, 2 inner surface top and the bottom of expansion sleeve be equipped with symmetrical two conical surfaces, respectively with rotation expansion core 1 appearance
The outer surface conical surface of face cone face and pedestal expansion core 3 matches, and realizes that the expansion to expansion sleeve 2 is expanded, symmetrical two conical surfaces are set
It sets and ensure that the uniformity for expanding the expansion of expansion sleeve 2 force, improve stability when 2 enlarged outside diameter of expansion sleeve, guarantee
The cylindricity for inside diameter and internal-and external diameter concentricity of magnetic bearing stator lasmination 10 and the parallelism precision of end face can reach quality
It is required that.
In the present invention, rotating expansion core 1 and pedestal expansion core 3 can synchronize and carry out the opposite position movement in direction, this to set
Meter ensure that the synchronous expansion that upper and lower both direction can be carried out to expansion sleeve 2 is expanded, and the expansion for effectively increasing expansion sleeve 2 is expanded
Mesenchymal amount.
As shown in Figs. 1-2, two ball bearings 5 symmetrical above and below are equipped in rotation expansion core 1；The step on 4 top of rotary shaft is set
Between two ball bearings 5, rotary shaft 4 rotates on ball bearing 5.
As shown in Figs. 1-2, rotation expansion core 1 is equipped with inner cavity, and two ball bearings 5 are respectively provided in the lumen, inner cavity lower ending opening
Equipped with bearing cap 6, bearing cap 6 is fixed by screw 7 and rotation expansion core 1.
In practical application of the invention, rotation expansion core 1, expansion sleeve 2 and pedestal expansion core 3 are at assembled state, rotation first
The 4 bottom end external screw thread of rotary shaft of expansion core 1 is threadedly coupled with 3 screw top hole of pedestal expansion core, and expansion sleeve 2 is set in rotation expansion core 1
And 3 outside of pedestal expansion core；Rotary shaft 4 is first rotated by interior six sides counterbore with die nut, makes to rotate expansion core 1 and pedestal expansion core 3
Between distance become larger, expansion sleeve 2 is in relaxation state, then successively by magnetic bearing stator lower loop 11, required amount of magnetic axis
Hold stator lasmination 10 and magnetic bearing stator top ring 8 be set in outside expansion sleeve 2, at this time 10 internal diameter of magnetic bearing stator lasmination with it is swollen
There is certain interval between fixed 2 outer surface, facilitate being put into for magnetic bearing stator lasmination 10.Further, then it is logical with die nut
Six side's counterbores rotation rotary shaft 4 in crossing makes to rotate distance between expansion core 1 and pedestal expansion core 3 and becomes smaller, at this time due to rotating expansion core 1
Outer surface is matched with 2 inner surface top conical surface shape of expansion sleeve, 3 outer surface of pedestal expansion core and 2 inner surface lower cone of expansion sleeve
Face shape matches, and when rotation expansion core 1 moves down, pedestal expansion core 3 also generates the movement upward relative to expansion sleeve 2, therefore
The effect of enlarged outside diameter expansion can be generated to expansion sleeve 2 by rotating expansion core 1 and pedestal expansion core 3, make 2 outer surface of expansion sleeve and magnetic bearing
10 internal diameter of stator lasmination is in contact complete fitting, and all magnetic bearing stator lasminations 10 is made to realize coaxial positioning, and magnetic bearing is fixed at this time
The cylindricity for inside diameter and internal-and external diameter concentricity of sub- lamination 10 and the parallelism precision of end face can reach quality requirement, further
Magnetic bearing stator top ring 8, magnetic bearing stator lasmination 10 and magnetic bearing stator lower loop 11 are connected using long spiro nail 9, completes magnetic
Suspension bearing stator module laminates assembling.Finally without removing expansion core, and die nut is used to rotate by interior six sides counterbore
Rotary shaft 4 makes to rotate distance between expansion core 1 and pedestal expansion core 3 and becomes larger, removes the enlarged outside diameter expansion of expansion sleeve 2, increase
Gap between 2 outer surface of expansion sleeve and suspension bearing stator module internal diameter facilitates assembled magnetic suspension bearing stator pack
Part takes out.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
