Abstract
The utility model discloses an apron and skeleton assembly structure of motor, including apron, skeleton, the locating hole has been seted up on the apron, be equipped with the reference column on the skeleton, the locating hole with the reference column position is corresponding, the locating hole the reference column respectively two a set ofly set up in pairs, the locating hole diameter D1 be greater than location column diameter D2, it is a set of the interval D3 of locating hole is greater than a set ofly the interval D4 of reference column. The utility model has the advantage of simple structure, required precision to the size when part is made reduces, but convenient assembling, and the assembly degree of difficulty reduces, not wearing and tearing of part during the assembly to assembly back sound construction.
Description
Technical field
The utility model relates to a kind of cover plate of motor and the assembly structure of skeleton.
Background technology
What use in the MOD of refrigerator is all micromachine, and as shown in Figure 1, cover plate 1 and the skeleton 2 of motor first assemble, and then form coil to skeleton 2 coiling.Cover plate 1 and skeleton 2 flexibly connect, but have certain bonding strength after requiring assembling, prevents both from getting loose.
Existing structure adopts hole post orientation assemble, namely on cover plate 1, offers location hole 3, skeleton 2 is provided with reference column 4, cooperatively interacts, and realizes assembling.Its shortcoming is: when location hole internal diameter size and reference column outside dimension interference fit, reference column can be put in location hole, but due to both sizes the same, cut mutually when assembling can produce plastics bits, install also hard; And during matched in clearance, although install easily, skeleton easily on the cover board gets loose.
Utility model content
Utility model object: for the problems referred to above, the purpose of this utility model be to provide a kind of easy for installation, parts are not damaged, the cover plate of motor that is connected firmly and Skeleton assembly structure.
Technical scheme: a kind of cover plate of motor and Skeleton assembly structure, comprise cover plate, skeleton, described cover plate offers location hole, described skeleton is provided with reference column, described location hole is corresponding with described reference column position, two one compositions are to setting respectively for described location hole, described reference column, and described location hole diameter D1 is greater than described reference column diameter D2, and described in one group, the space D 3 of location hole is greater than the space D 4 of reference column described in a group.
The pass of described location hole diameter D1 and described reference column diameter D2 is D1=(1.0 ~ 1.05) D2.
Described in the space D 3 of location hole described in a group and one group, the pass of the space D 4 of reference column is D3=(1.005 ~ 1.015) D4.
Best, described location hole, described reference column arrange one group at least respectively in pairs, improve the fastness of assembly structure.
Best, described location hole, described reference column respectively Central Symmetry are arranged, and facilitate the manufacture of parts.
Beneficial effect: compared with prior art, the utility model has the advantages that structure is simple, the required precision for size when parts manufacture reduces, but easy to assembly, and assembly difficulty reduces, and during assembling, parts do not wear and tear, and sound construction after assembling.
Accompanying drawing explanation
Fig. 1 is cover plate and the skeleton structure schematic diagram of existing motor;
Fig. 2 is the utility model cover plate structural representation;
Fig. 3 is skeleton structure schematic diagram in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
A kind of cover plate of motor and Skeleton assembly structure, as shown in accompanying drawing 2,3, comprise cover plate 1 and on location hole 3, skeleton 2 and the reference column 4 which is provided with offered, location hole 3 is corresponding with the position of reference column 4, the diameter D1 of location hole 3 is greater than the diameter D2 of reference column 4, when mounted, reference column 4 is easily put in location hole 3, and location hole 3, reference column 4 difference two one compositions are to setting, the one group location hole 3 corresponding for position and reference column 4, the space D 3 of location hole 3 is greater than the space D 4 of reference column 4.
The pass of D1 and D2 is D1=(1.0 ~ 1.05) D2; The pass of D3 and D4 is D3=(1.005 ~ 1.015) D4.
When the spacing of location hole is greater than the spacing of reference column, after cover plate and Skeleton assembly, skeleton is stretched out, under tension, can ensure the bonding strength with cover plate, and now, what skeleton was subject to is outside tensile force, skeleton can smooth fitting with cover plate.Neither affect use, be provided with again certain bonding strength.
And if when the spacing of reference column is greater than the spacing of location hole, when reference column inserts location hole, under tension, although make cover plate not easily get loose, now, skeleton is to center compression for skeleton, can not be very smooth fit with cover plate, impact uses.
In order to the fastness of assembly structure, location hole 3, reference column 4 arrange one group at least respectively in pairs.In order to parts are easily manufactured, location hole 3, reference column 4 respectively Central Symmetry are arranged in pairs.
