Abstract
The utility model discloses a rotor core goes into axle device, including the frame, be equipped with the hydraulic press in the frame, the piston rod terminus of hydraulic press is equipped with and is used for impress rotor core's pressure head of rotor shaft, the frame bottom is equipped with the workstation, be fixed with the lower mould on the workstation, the lower mould center is equipped with the nib that is used for fixed rotor core, is equipped with the last mould rather than matched with on the lower mould, be equipped with the diaphragm directly over the lower mould, the diaphragm center is equipped with the through -hole that is used for the rotor shaft to pass, and the terminal surface is equipped with the dead lever under the diaphragm, and the end of dead lever is fixed in the frame bottom. Since the technical scheme is used, the utility model discloses a rotor core goes into axle device, because the limiting displacement of diaphragm and dead lever, the height -adjustable of dead lever moreover can prevent that the pressure head from impressing the rotor shaft excessively, sets up the spring between diaphragm and the dead lever top and can prevent that the pressure head from crusing the diaphragm by pressure. The utility model discloses simple structure can improve the yield of rotor moreover.
Description
Technical field
This utility model relates to motor device technical field, and particularly a kind of rotor core enters shaft device.
Background technology
At present; motor is when assembling; load in rotor core firstly the need of by axle; existing general expression shaft press by directly entering in rotor iron filings by axial compression after fixing for rotor core; but due to when being pressed into axle, it is difficult to ensure that armature spindle puts in place after entering rotor core, the problem that armature spindle press-in is excessive often occurs; or cause that armature spindle bends to deform, reduce the yield rate of rotor.
Utility model content
The purpose of this utility model is just to provide a kind of simple in construction, and the rotor core that can improve the yield rate of rotor enters shaft device.
The purpose of this utility model is realized by such technical scheme: a kind of rotor core enters shaft device, including frame, frame is provided with hydraulic press, the piston-rod end of hydraulic press is provided with the pressure head for armature spindle is pressed into rotor core, it is provided with workbench bottom described frame, described workbench is fixed with counterdie, counterdie center is provided with the nib for fixed rotor iron core, it is provided with transverse slat directly over described counterdie, transverse slat center is provided with the through hole for armature spindle traverse, transverse slat lower surface is provided with fixing bar, and the end of fixing bar is fixed on bottom frame.
Further, it is provided with spring between described fixing masthead end and transverse slat lower surface.
Further, being threaded connection bottom the end of described fixing bar and frame, the end of fixing bar is provided with locking nut.
Further, the distal center of described pressure head is provided with the counterbore matched with armature spindle.
Owing to have employed technique scheme, this utility model has the advantage that
Rotor core of the present utility model enters shaft device, due to the position-limiting action of transverse slat and fixing bar, and the height adjustable of fixing bar, it is possible to prevent pressure head to be pressed into by armature spindle excessive, arranges spring and be prevented from pressure head and damaged by pressure by transverse slat between transverse slat and fixing masthead end. This utility model simple in construction, and the yield rate of rotor can be improved.
Other advantages of the present utility model, target and feature will be illustrated to a certain extent in the following description, and to a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and claims and obtain.
Accompanying drawing explanation
Accompanying drawing of the present utility model illustrates as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the upward view of pressure head of the present utility model.
In figure: 1. frame; 2. hydraulic press; 3. workbench; 4. counterdie; 5. transverse slat; 6. through hole; 7. pressure head; 8. fixing bar; 9. rotor core; 10. armature spindle; 11. nib; 12. counterbore; 13. spring; 14. locking nut.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of rotor core of the present embodiment enters shaft device, including frame 1, frame 1 is provided with hydraulic press 2, the piston-rod end of hydraulic press 2 is provided with the pressure head 7 for armature spindle 10 is pressed into rotor core 9, it is provided with workbench 3 bottom described frame 1, described workbench 3 is fixed with counterdie 4, counterdie 4 center is provided with the nib 11 for fixed rotor iron core 9, it is provided with transverse slat 5 directly over described counterdie 4, transverse slat 5 center is provided with the through hole 6 for armature spindle 10 traverse, and transverse slat 5 lower surface is provided with fixing bar 8, and the end of fixing bar 8 is fixed on bottom frame 1.
As the improvement of the present embodiment, being provided with spring 13 between described fixing bar 8 top and transverse slat 5 lower surface, spring 13 can provide a cushion effect when hydraulic press 2 drive ram 7 moves downward, it is prevented that transverse slat 5 is damaged by pressure by pressure head.
Improvement as the present embodiment, it is threaded connection bottom the end of described fixing bar 8 and frame 1, the end of fixing bar 8 is provided with locking nut 14, can be used to regulate the height of fixing bar 8, and fix with locking nut 14, by regulating the height of fixing bar 8, that pressure head 7 can be stoped to be pressed into by armature spindle 10 is excessive.
As shown in Figure 2, improvement as the present embodiment, the distal center of described pressure head 7 is provided with the counterbore 12 matched with armature spindle 10, when pressure head 7 is pressed under the top to armature spindle 10, after counterbore 12 matches with armature spindle 10 top, can prevent the sliding of armature spindle 10 from making armature spindle 10 offset in rotor core 9.
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
