Further, the rear end of the first half of described electric machine casing forms front flange, the latter half of front end of described electric machine casing forms rear flange, on the rear flange of described front flange, be provided with a plurality of installation screws, fastening bolt be set in described installation screw by electric machine casing described in the first half of described electric machine casing and the latter half of shape that links together.
Further, the first half of described electric machine casing and latter half of between pars intermedia is set, described pars intermedia is tubulose, the size and shape of described pars intermedia and described first half and latter half of identical, the flange matching with the front flange of described first half and latter half of rear flange is all set at the two ends of described pars intermedia, on the flange of described pars intermedia, installation screw is set, by the fastening bolt in described installation screw by the first half of described electric machine casing, pars intermedia be latter half ofly joined together to form described electric machine casing.
Further, the cross sectional shape of described electric machine casing is circle or regular hexagon.
Further, the machining deviation of described each face of electric machine casing is less than 10 microns.
The beneficial effects of the utility model are:
(1) all by cold-extrusion technology, process for several of electric machine casing, casing quality obviously improves;
(2) electric machine casing is easy to assembly, can be assembled into different electric machine casing sizes;
(3) cold extrusion machining accuracy is high, and during follow-up machine work, dimensional accuracy can reach micron order.
Accompanying drawing explanation
Accompanying drawing 1 is the sectional structure chart of the first embodiment of the present utility model;
Accompanying drawing 2 is sectional structure charts of the second embodiment of the present utility model.
Label in accompanying drawing is:
1. electric machine casing; 2. first half;
3. latter half of; 4. electric machine casing head;
5. electric machine casing afterbody; 6. output shaft installing hole;
7. mesh dispels the heat; 8. front flange;
9. rear flange; 10. pars intermedia;
11. flanges.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model electric machine casing is elaborated.
Embodiment mono-:
Referring to accompanying drawing 1, electric machine casing 1 is by the first half 2 of electric machine casing 1 and latter half of 3 assembled, and the front end of first half 2 is electric machine casing head 4, and latter half of 3 rear end is electric machine casing afterbody 5.Electric machine casing head 4 has motor output shaft installing hole 6, and electric machine casing afterbody 5 has heat radiation mesh 7.
The rear end of the first half 2 of electric machine casing 1 forms front flange 8, latter half of 3 front end of electric machine casing 1 forms rear flange 9, on the rear flange 9 of front flange 8, be provided with a plurality of installation screws, fastening bolt be set in installation screw by the first half of the electric machine casing 12 and latter half of 3 shape electric machine casing 1 that links together.
The first half 2 of electric machine casing 1 and latter half of 3 is all realized by cold extrusion processing technics, after the material of electric machine casing 1 being softened to processing, by mould after cold extrusion shaped, carry out again fine finishining and make the finished part of first half and latter half of 3, finally can cross the finished product that fastening assembling completes electric machine casing 1.
It is circle and regular hexagon that the profile of electric machine casing 1 can be arranged to cross section as required, or other needed shape, all may cross cold extrusion and machine.
The finished product high conformity of cold extrusion processing, fine finishining precision is high, and the dimensioned deviation of its each machined surface is less than 10 microns.In addition, cold-extrusion technology is simple and convenient, low in the pollution of the environment, and product quality is easily controlled, and cost obviously reduces.
Embodiment bis-:
Referring to accompanying drawing 2, embodiment bis-is basic identical with embodiment mono-general structure, difference is, between the first half 2 and latter half of 3 of electric machine casing 1, pars intermedia 10 is set, pars intermedia 10 is tubulose, the size and shape of pars intermedia 10 and first half 2 and latter half of 3 identical, the flange 11 that rear flange 9 with the front flange 8 of first half 2 and latter half of 3 matches is all set at the two ends of pars intermedia 10, on the flange 11 of pars intermedia 10, installation screw is set, by the fastening bolt in installation screw by the first half of electric machine casing 12, pars intermedia 10 and latter half of 11 is joined together to form electric machine casing 1.
The introducing of pars intermedia 10, makes the cold extrusion processing of first half 2 and latter half of 3 convenient simple, is applicable to the situation that motor length is longer, and pars intermedia 10 also can adopt the technique of cold drawing to complete.The removable design of pars intermedia, not only easy to process, and maintenance of motor has also been brought to facility.
