The structure is characterized in that a motor end cover and a motor housing are axially positioned through contact of an end face of the motor end cover and an end face of the motor housing, and a pair of end cover dowel holes are disposed on the end face of the motor end cover. Corresponding to the end cover dowel holes, a pair of housing dowel holes are disposed on the end face of the motor housing, and locating pins are assembled in the end cover dowel holes and the housing dowel holes to obtain radial positioning. The structure is simple in structure, good in reliability, low in manufacturing cost, and simple and fast in assembling process. Applying the structure in the field of motor manufacturing, production efficiency can be effectively improved.
Description
Technical field
The utility model relates to the assembly structure of plane and two pits, relates in particular to the assembly structure of electric motor end cap and electric machine casing.
Background technology
Along with current industrial expansion, market is just increasing to the demand of industrial motor, and the production capacity of general factory is just difficult to meet the demand in market, in order to change this present situation only way, increase exactly new equipment and increase labourer's quantity, so certainly will bring the increase of equipment cost and labor cost, and motor manufacturing belongs to labor-intensive enterprises, the increase of equipment cost and labor cost will bring for the development of enterprise huge burden, thereby can affect the normal development of enterprise.
Traditional electric motor end cap and electric machine casing are all the assembling modes that adopts one side one seam, electric motor end cap and electric machine casing are axially being located by the two end contact, by the male half coupling on end cap, coordinate realization location with the inner stopper formation on casing diametrically, this assembling mode is very high for processing request, two seams must have higher machining accuracy guarantee well to coordinate, will improve percent defective like this, moreover seam assembling is more difficult, has reduced to a certain extent production efficiency.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, and the motor assembling structure of the plane and two pits of a kind of simple in structure, good reliability, low cost of manufacture is provided, and is applied to field of motor manufacturing, to enhance productivity.
The utility model is that technical solution problem adopts following technical scheme:
The feature of the motor assembling structure of the utility model plane and two pits is: electric motor end cap and electric machine casing are with electric motor end cap end face and the electric machine casing end face acquisition axial location that contacts; A pair of end cap dowel hole is set on described electric motor end cap end face; Corresponding to described end cap dowel hole, on described electric machine casing end face, pair of shells dowel hole is set, and has alignment pin to be assemblied in end cap dowel hole and housing dowel hole to obtain radial location.
The feature of the motor assembling structure of the utility model plane and two pits is also:
Described alignment pin and housing dowel hole are interference fit, and described alignment pin and end cap dowel hole are little matched in clearance.
Described electric motor end cap is connected by screw fastening with electric machine casing.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, compare with the assembly structure of traditional one side one seam, the assembling mode pin hole processing of the utility model plane and two pits is simpler, has reduced percent defective, and assembling process is more simple and convenient, has effectively improved production efficiency.
2, simple in structure, the good reliability of the motor of the utility model plane and two pits assembling mode, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the utility model electric motor end cap and electric machine casing assembly structure schematic diagram;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 a, Fig. 3 b, Fig. 3 c and Fig. 3 d are the utility model assembling process flow chart.
Number in the figure: 1 electric machine casing; 1a housing dowel hole; 2 alignment pins; 3 electric motor end caps; 3a end cap dowel hole; 4 screws.
Embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, the motor assembling structure of plane and two pits is: electric motor end cap 3 and electric machine casing 1 are with electric motor end cap end face and the electric machine casing end face acquisition axial location that contacts; A pair of end cap dowel hole 3a is set on the end face of electric motor end cap 3; Corresponding to end cap dowel hole 3a, pair of shells dowel hole 1a is set on the end face of electric machine casing 1, and has alignment pin 2 to be assemblied in end cap dowel hole 3a and housing dowel hole 1a to obtain radial location.
In the present embodiment, alignment pin 2 is interference fit with housing dowel hole 1a, and alignment pin 2 is little matched in clearance with end cap dowel hole 3a; Between electric motor end cap 3 and electric machine casing 1, by screw 4, be fastenedly connected.
In concrete enforcement, need to guarantee the flatness of end face of electric motor end cap 3 and electric machine casing 1 and each dowel hole and for the position degree of the screw hole of trip bolt 4.
In the present embodiment, the assembling mode of the motor assembling structure of plane and two pits is to carry out as follows:
The first step, the mode by two alignment pins 2 by interference fit are enclosed in the housing dowel hole 1a of electric machine casing 1 (as shown in Figure 3 a);
Second step, the end face by the end face of electric motor end cap 3 towards electric machine casing 1, and two alignment pins 2 are dropped in end cap dowel hole 3a, realize axial location and radial location (as shown in Figure 3 b) between electric motor end cap 3 and electric machine casing 1;
The 3rd step, electric motor end cap 3 and electric machine casing 1 have been fastenedly connected to assembling (as shown in Figure 3 c with shown in Fig. 3 d) by screw 4.
The electric motor end cap of the utility model plane and two pits and the assembly structure of electric machine casing have improved product safety reliability effectively, improved efficiency of assembling, improved assembly quality and stability, its technique is simply effective, conversion flexibly, is applicable to various types of motor assemblings.
