The device for stability of rotor coaxiality not only improves the precision of rotor products, but also greatly improves production efficiency and reduces labor cost, thereby improving the competitive capacity of enterprises.
Description
Technical field
The utility model relates to the stability devices for the rotor coaxial degree of electric machine rotor mould.
Background technology
This series products scope of application is very wide, is almost used in the folded riveting mould of all high-speed electric expreess locomotive rotors.Currently available technology is that the rotor of motor is in folded riveting process, rotary sleeve is unidirectional location, in process of production because bearing runs up for a long time, high temperature and friction that its High Rotation Speed produces, cause positioning gap excessive, can make rotary sleeve swing and strengthen, rotary sleeve is done oscillating motion around axle center, affect the stability of rotary sleeve, the quality of rotor product is had to very important impact.Therefore, a structural design difficult problem for the stability of the rotor coaxial degree of solution electric machine rotor mould and complicated processing technology are current problem demanding prompt solutions.
Summary of the invention
Technical problem to be solved in the utility model is: the structural design of the stability of the rotor coaxial degree of electric machine rotor mould.
The technical scheme in the invention for solving the above technical problem is:
The stability devices of rotor coaxial degree, comprises concave template, is positioned at the lower bolster of concave template below; Two-way position rotating cover is installed in concave template and lower bolster; Two-way position rotating cover is open circles tubular rotary sleeve, upper circular cover, the circular cover in middle part and bottom circular cover three part integral types, consists of; The circular cover in middle part is clamped by a upper bearing (metal), and the lower end of the circular cover in bottom is clamped by a lower bearing; Two-way position rotating is overlapped exterior be furnished with worm gear and the worm screw supporting with it.
Described upper circular cover slidingtype is contained in concave template, and the circular cover of the circular cover in middle part and bottom is positioned at lower bolster.
The diameter of described upper circular cover, the circular cover in middle part, the circular cover in bottom dwindles successively.
Described upper bearing (metal), lower bearing are fixed by the upper bearing (metal) positioning sleeve and the lower bearing positioning sleeve that are assemblied in lower bolster respectively.
Worm gear and the worm screw supporting with it are to be assemblied in outside the circular cover in bottom.
Worm gear bottom is clamped by jump ring.
Outside, upper circular cover lower end described, is provided with location-plate it is located; Upper location-plate is fixedly mounted on upper bearing (metal) positioning sleeve tip position.
In described bottom, outside, circular set upper side, is provided with lower location-plate it is located.
The utility model has the advantage of: by original unidirectional location, change two-way location into, overcome preferably unidirectional position rotating and be enclosed within the defect that produces swing in High Rotation Speed, reduced the unsteadiness of moving in height rotary course, guarantee the stability of product quality, improved largely the quality of rotor product.Unidirectional location changes into behind two-way location, the corresponding raising of the accuracy of manufacture of mould, and associated parts have concave template, die shoe and bearing positioning sleeve, the location hole required precision of mounting panel is very high.Concentricity <0.002mm after assembling, relies on the precise machining equipments such as coordinate mill, slow wire feeding, guarantees that assembly precision reaches requirement.The utility model has not only improved the precision of rotor product, and has greatly improved production efficiency and reduced cost of labor, thereby has improved the competitiveness of enterprise.

Embodiment
Below in conjunction with accompanying drawing, to apparatus structure of the present utility model and operating procedure, be further described as follows:
Referring to Fig. 1, the utility model comprises concave template 1, is positioned at the lower bolster 2 of concave template 1 below and is arranged on concave template 1 and the two-way position rotating of lower bolster 2 overlaps 3.The structure of described two-way position rotating cover 3 as shown in Figure 2, is open circles tubular rotary sleeve, upper circular cover 3.1, the circular cover 3.2 in middle part and bottom circular cover 3.3 3 part integral types, consists of.The diameter of upper circular cover 3.1, the circular cover 3.2 in middle part, the circular cover 3.3 in bottom dwindles successively.Upper circular is overlapped 3.1 slidingtypes and is contained in concave template 1, and the circular cover 3.3 of the circular cover 3.2 in middle part and bottom is positioned at lower bolster 2.The circular cover 3.2 in middle part is by upper bearing (metal) 6 clampings, and the lower end of the circular cover 3.3 in bottom is by lower bearing 8 clampings.Described upper bearing (metal) 6, lower bearing 8 are fixed by the upper bearing (metal) positioning sleeve 7 and the lower bearing positioning sleeve 9 that are assemblied in lower bolster 2 respectively again.
In bottom, circular cover 3.3 is exterior is furnished with worm gear 4 and the worm screw 5 supporting with it.By worm screw 5, rotate worm gear 4 for two-way position rotating cover 3 provides power, thereby drive two-way position rotating to overlap 3, rotate.Worm gear 4 bottoms are clamped by jump ring 12.
In described upper circular, overlap 3.1 outsides, lower end, be provided with location-plate 10 to its location, upper location-plate 10 is fixedly mounted on upper bearing (metal) positioning sleeve 7 tip positions.In described bottom, circular cover 3.3 outsides, upper end, are provided with lower location-plate 11 to its location.Two-way position rotating cover 3 is owing to there being the Dual positioning of upper location-plate 10 and lower location-plate 11, and the multiple spot of adding concave template 1, upper bearing (metal) 6 and lower bearing 8 is spacing, is limited to securely in concave template 1 and lower bolster 2.Adopt after said structure, two-way position rotating cover 3 is all positioned in concave template 1 and lower bolster 2 from top to bottom securely, during long-term High Rotation Speed, also can not produce swing, has guaranteed the stability of product quality.
