Described expansion set is established 3 elastic grooves, the symmetrical centre face of described elastic groove two sides and the dead in line of described mandrel, and the conical surface through expansion set cooperates with the truncated cone-shaped tapering of described mandrel;
On the circumference of the cross section of described expansion set, described elastic groove evenly distributes;
Described pressing plate is enclosed within round platform small end one side of mandrel;
Described locking nut is enclosed within on the mandrel and through being threaded.
The novelty of the utility model, creativeness and practicality also are embodied in the following more detailed and concrete technical scheme, can realize goal of the invention better:
End face to the mandrel of the big end of round platform of described mandrel does not have the end face distance of screw thread one end greater than 1/2nd of mandrel length overall;
The round platform axial length of described mandrel is not more than the axial length of expansion set;
Described expansion set radially protrudes 2mm with the outer rim of the end face that the big end of round platform of mandrel cooperates.
The utility model adopts technique scheme, compared with prior art, has improved small power motor stator dismounting effect, has guaranteed that the intact and support of stator is not damaged yet.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification and the figure is made brief description:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sketch map of stator dismounting frock in the structure shown in Figure 1.
Be labeled as among the figure:
1, mandrel, 2, expansion set, 3, pressing plate, 4, locking nut, 5, stator, 6, support.
Embodiment
Contrast accompanying drawing below; Through description to embodiment; To effect and operation principle, the manufacturing process of the mutual alignment between the shape of the embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc.; Do further detailed explanation, inventive concept of the present invention, technical scheme are had more complete, accurate and deep understanding to help those skilled in the art.
Like the structure of the expressed the utility model of Fig. 1, Fig. 2, be a kind of stator dismounting frock of small power motor, comprise mandrel 1, expansion set 2, pressing plate 3, locking nut 4.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective; Realize improving small power motor stator dismounting effect; Guarantee the goal of the invention that stator is intact and support is not damaged, the technical scheme that the utility model is taked is:
Like Fig. 1, shown in Figure 2, the stator of this small power motor that the utility model provided dismounting frock comprises mandrel 1, expansion set 2, pressing plate 3, locking nut 4, and described mandrel 1 is for column and be provided with round platform, the axis of this round platform and the dead in line of this column; Mandrel 1 end of round platform small end one side of described mandrel 1 is provided with screw thread; Described expansion set 2 is established 3 elastic grooves, the symmetrical centre face of described elastic groove two sides and the dead in line of described mandrel 1, and the conical surface through expansion set 2 cooperates with the truncated cone-shaped tapering of described mandrel 1; On the circumference of the cross section of described expansion set 2, described elastic groove evenly distributes; Described pressing plate 3 is enclosed within round platform small end one side of mandrel 1; Described locking nut 4 is enclosed within on the mandrel 1 and through being threaded.
Adopt such scheme; Mandrel, the expansion set of small power motor stator dismounting frock are put into the stator circle from U-shaped support opening part; On mandrel, make expansion set identical and fixing through the locking nut of screwing behind the cover top board with circle in the stator; On forcing press, aim at the mandrel end face pressurization that bearing chamber hole, U-shaped support bottom surface passes again stator is extruded, can guarantee that the intact and support of stator is not damaged.
