Description
Technical field
This utility model relates to mechanical field, particularly relates to a kind of submersible motor stator tire.
Background technology
After stator press-loading manufacture completes, need to carry out the machine tooling of degree of precision.The stator feature of submersible motor is thin
Long, it is difficult to by traditional clamping.The shortcoming that processing exists: the required precision of 1 pair of equipment is high；2 form and position tolerances are difficult to protect
Card；3 clamp precisions it cannot be guaranteed that.
Utility model content
The purpose of utility model: in order to provide a kind of effect more preferable submersible motor stator tire, specific purposes are shown in specifically
Multiple substantial technological effects of implementation section.
In order to reach as above purpose, this utility model adopts the following technical scheme that:
A kind of submersible motor stator tire, it is characterised in that comprise mandrel, mandrel comprises two inner conical surfaces, also comprises
Two elastic expansion sleeves, two elastic expansion sleeves are the conical surface at two, and elastic expansion sleeve assembles with inner conical surface resilient sleeve, also comprises two nuts
Set, nut sleeve is enclosed within the thread segment of mandrel, and the end of nut sleeve is positioned at inside expansion set, elastic expansion when nut sleeve rotates when
Set can produce radial displacement.
The further technical scheme of this utility model is, said two inner conical surface and two elastic expansion sleeves are around in mandrel
Heart lateral symmetry is distributed.
The further technical scheme of this utility model is, each self-contained step surface on the described conical surface and elastic expansion sleeve, respectively
Self-contained step surface can coordinate.
The further technical scheme of this utility model is, the end of described nut sleeve be positioned at the inclined-plane within elastic expansion sleeve or
In person's groove.
Use this utility model of as above technical scheme, have the advantages that relative to prior art: make conventional equipment
Disclosure satisfy that the requirement processing this part, tire and stator are assembled into one, use tapering elastic deformation to ensure processing
Form and position tolerance, it is ensured that the concordance of clamping every time and required precision.
Accompanying drawing explanation
In order to further illustrate this utility model, it is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is this utility model structural representation；
Fig. 2 is the structural representation that this utility model clamps；
Wherein: 1. nut sleeve；2. elastic expansion sleeve；3. mandrel；4. stator；5. tire.
Detailed description of the invention
Illustrating embodiment of the present utility model below in conjunction with the accompanying drawings, embodiment is not constituted limit of the present utility model
System:
A kind of submersible motor stator tire, it is characterised in that comprise mandrel, mandrel comprises two inner conical surfaces, also comprises
Two elastic expansion sleeves, two elastic expansion sleeves are the conical surface at two, and elastic expansion sleeve assembles with inner conical surface resilient sleeve, also comprises two nuts
Set, nut sleeve is enclosed within the thread segment of mandrel, and the end of nut sleeve is positioned at inside expansion set, elastic expansion when nut sleeve rotates when
Set can produce radial displacement.Technique effect and the process that realizes thereof of the essence that the technical scheme at this place is played are as follows: fixed
Press-fiting of sub-iron core is to complete on special mandrel, and mandrel needs to complete by large-scale oil pressure unit with the assembling of stator,
Assembly or disassembly is the most pretty troublesome, and assembly precision is difficult to control, and repeatedly assembles and workpiece and mandrel are all had damage.
Utilizing cone match to assemble, the mandrel of tire designs the conical surface at two, assembles with the i.e. expansion set of inner conical surface resilient sleeve, uses
Screw thread linkage inner cone surface cover, makes inner cone surface cover i.e. expansion set occur radial shape to become under the conical surface effect of mandrel, reaches and stator essence
The purpose of quasi-assembling.
Workpiece to be processed is encased on tire, with Special rotary spanner fastening nut, promotes cone to produce axial displacement,
The expansion set making elasticity produces radially deformation, reaches to clamp the purpose of workpiece to be processed.
As preferably, said two inner conical surface and two elastic expansion sleeves are distributed around mandrel center lateral symmetry.Described
Each self-contained step surface on the conical surface and elastic expansion sleeve, each self-contained step surface can coordinate.The position, end of described nut sleeve
In the inclined-plane within elastic expansion sleeve or groove.Prior art uses the press-in of iron core laminated mandrel and extrusion type, is formed tight
Coordinate the purpose reaching clamping.After needing to install by press device, the lathe of lifting is processed.There is clamping
Time-consuming long, need just can complete by other equipment, use cost is high, and efficiency is low.Using this utility model is that manpower is with special
Spanner gold section completes handling, it is only necessary to is assembled on tire by workpiece to be processed, screws i.e. with special tightening tool manpower
Can reach the purpose of processing.Utilize this utility model to eliminate press device and hanging device, saved the time of clamping, improve
Labor efficiency and energy-conservation purpose.
The conical surface at two, two ends are designed as can clamping and hold out against dual-purpose.Nut sleeve and elastic expansion sleeve are the assembling of linkage formula, will
Nut sleeve and elastic expansion sleeve are encased in mandrel, when nut sleeve counterclockwise or when turning clockwise, carries on the screw thread of mandrel
Dynamic elasticity expansion set moves on the mandrel conical surface.Owing to the conical surface of elastic expansion sleeve Yu axle is cone match, elastic expansion sleeve can produce footpath
To deformation, reach the purpose of clamping workpiece.
In a creative way, each effect above is individually present, moreover it is possible to complete the combination of the above results with a nested structure.
The technique effect that above structure realizes realizes clear, and discounting for additional technical scheme, this patent title is also
Can be that one squeezes structure.Part details not shown in figure.
It should be noted that multiple schemes that this patent provides comprise the basic scheme of itself, separate, the most mutually
Restriction, but it can also be mutually combined in the case of not conflicting, and reaches multiple effect and jointly realizes.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Ability
Territory skilled person will appreciate that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model also can
Having various changes and modifications, these changes and improvements both fall within claimed scope.
