Preferred scheme is, the described pressure element that rises is screw rod.Described screw rod can guarantee sealing, guarantees that the pressure transmitter substance does not flow out, and can carry larger squeeze pressure.
Preferred scheme is that described pressure transmitter substance is for softness and have flexible fluid or semi-solid gluey plastics.Described plastics can not harden at normal temperatures, remain soft flexible, when unclamp press the element that rises after, immediate recovery relaxed state, thin-walled ringfeder also together recover.
Preferred scheme is, described expander body is made of columned main body and the axial region that is positioned at this main body both sides, and described main body is coaxial with axial region, and the outer end of described axial region is equipped with expander silently.Described expander is silently different from the material of main body, and expander silently needs to coordinate with lathe centre, and material behavior requires high, and as unified material, high cost causes waste.Silently damage as expander, conveniently replaced.
Preferred scheme is, the described pressure passage that rises runs through the main body of described expander body, is used for the filling pressure transmitter substance and extruding connects.
Preferred scheme is, the described pressure chamber of rising also is connected with the external world via the exhaust passage, and the exit that described exhaust passage is connected with the external world is provided with the pore bolt.Described exhaust passage is used for discharging the air of pressing in the chamber of rising in the hot pressure transmitter substance of can process, presses in the chamber of rising without air with assurance.
Compared with prior art, expander device of the present utility model can be enhanced productivity, and reduces employee's operation easier, guarantees processing precision of products and reduces cost of goods manufactured.

Embodiment
Consult Fig. 2 and Fig. 3, a kind of iron core expander device 10 of the present utility model, comprise expander body 1, thin-walled ringfeder 2, expander silently 3, press the screw rod 4 that rises, pressure to transmit plastics 5, pore bolt 6 etc., be used for realizing connecting and the effect of tensioner electric machine rotor with lathe.
Described expander body 1 is made of columned main body 11 and the axial region 12,13 that is positioned at this main body 11 both sides, described main body 11 and two axial regions 12,13 coaxial, two expanders silently 3 are arranged on respectively two axial regions 12,13 outer end, are used for coordinating with Double Tops point lathe.Main body 11 is provided with presses rise passage 8 and exhaust passage 9.
Described thin-walled ringfeder 2 is cylindrical sleeve, it is sheathed on the outer surface of the main body 11 of expander body 1; have between the inwall 21 of thin-walled ringfeder 2 and the outer surface of expander body 1 and press the chamber 7 of rising; press the chamber 7 of rising to be connected with the external world via the pressure of the main body 11 that runs through expander body 1 passage 8 that rises; also be connected with the external world via exhaust passage 9 simultaneously, pore bolt 6 is arranged on the exit that exhaust passage 9 is connected with the external world.Pressure transmits plastics 5 and can be filled in and press rise chamber 7 and pressure to rise in passage 8.The pressure screw rod 4 that rises is arranged on the porch of pressing the passage 8 that rises to be connected with the external world, is used for pressure transmission plastics 5 are exerted pressure.In the present embodiment, pressure transmission plastics 5 adopt the number of chemical materials to boil at a certain temperature by a certain percentage and become softness and have flexible fluid or the plastics of semi-solid gluey (for example " jelly " shape).
According to Fig. 1, each parts are assembled.At first, after expander body 1 heating, with expander 3 two ends of knocking in expander body 1 silently, then thin-walled ringfeder 2 hot jackets are entered expander body 1 and form assembly.First pore bolt 6 is backed out, the outlet of exhaust passage 9 is opened, then with the whole heating of iron core expander device 10, re-using funnel transmits plastics 5 with the pressure of hot liquid and pours in assembly from passage 8 entrances that rise of the pressure on expander body 1, and be filled to and press the chamber 7 of rising, press the interior original air in chamber 7 that rises 9 to discharge from the exhaust passage, after air is discharged fully, with pore bolt 6 with the outlet of exhaust passage 9 sealing, plastics generation seepage when avoiding pressurizeing.After the plastic cool that pours into, load onto and press the screw rod 4 that rises, but keep loosening state.Pressure transmits plastics 5 for softness and has flexible fluid or semi-solid gluey plastics, press screw rod 4 squeeze pressures that rise to transmit plastics 5 by tightening, pressure transmits plastics 5 and pressure is passed to the inwall 21 of thin-walled ringfeder 2, makes thin-walled ringfeder 2 outer circumference surface swells (unclamp and press the rear recovery of screw rod 4 of rising).
During use, the pressure screw rod 3 that rises is unscrewed, iron core expander device 10 is slowly put into the rotor endoporus, then tighten and press the screw rod 3 that rises to make the tight interlock of inner peripheral surface of thin-walled ringfeder 2 outer circumference surfaces and rotor, make under the smear metal power effect that both produces when Vehicle Processing without relative sliding.After the locking rotor, with its wheeled litter cylindrical of getting on the bus, after completing processing, unclamp and press the screw rod 4 that rises, thin-walled ringfeder 2 outer circumference surfaces are recovered, can conveniently take out frock.For being used for all length rotor turning in the expander length range, can guarantee well that all the inside and outside circle of product is concentric.Compared with prior art, expander device of the present utility model can be enhanced productivity, and reduces employee's operation easier, guarantees processing precision of products and reduces cost of goods manufactured.
Above-described is only preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the present utility model design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
