Impeller is carried out it is circumferentially positioned, so that it is guaranteed that after mounting baffle plate when, the turbine disk is not in rotate, when rotating certain to rear baffle
Rear baffle can be caught in the turbine disk inner groove during individual angle.
It is detachable connection as preferred scheme of the present utility model, between the snap ring and hold-down ring.Using so
Design can be convenient for changing snap ring.
As preferred scheme of the present utility model, the hold-down ring outer wall is provided with multiple pivoted arms.By in hold-down ring outer wall
Multiple pivoted arms are set, to drive rear baffle to rotate, convenient operation.
As preferred scheme of the present utility model, the clamp nut is provided with multiple rotation holes.By in clamp nut
It is upper that multiple rotation holes are set, so that using circular rod member insertion rotation hole, the convenient clamp nut that screws in is with regulating sleeve axial direction position
Put, so as to drive rear baffle to produce axial deformation.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
The utility model drives rear baffle to produce axial deformation by using clamp nut is screwed in, then can be by percentage
Table measurement pressure strip face deformation grasps its deflection, when deflection, which reaches, to be required, rotates pivoted arm and drives rear baffle rotation, lead to
The angle groove for crossing reading pressure strip upper surface determines the anglec of rotation of rear baffle, rear baffle is reached specified location, to ensure
Lug on rear baffle is caught in turbine disk inner groove completely.
