Abstract
The utility model provides a fixing structure of a pump body component of a rotary compressor, which comprises an upper flange, a cylinder, a clapboard, a lower flange and a fixing frame, wherein the upper flange is fixed with the fixing frame; and one end of the spring stop block is fixed with the fixing frame, and the other end of the spring stop block is matched with the outer wall of the air cylinder and abuts against a sliding sheet spring arranged in the air cylinder. The shell of the compressor of the utility model is directly welded and assembled with the fixed frame, and does not need to act with the pump body component, thus reducing the influence of thermal deformation on the pump body component; when the compressor is abnormally scrapped, the pump body assembly can be completely disassembled for reuse only by unscrewing the screw, so that the scrappage of the pump body assembly is reduced; the upper flange is sunk into the fixing frame, so that the overall height of the compressor can be reduced, and related part materials used by the pump body assembly are reduced.
Description
Technical field
The utility model relates to the Compressor Technology field, specifically a kind of fixed structure of pump assembly of rotary compressor.
Background technique
Compressor is the core component in the electrical equipment such as air-conditioning, refrigerator, not only affect the service behaviour of complete machine, and its cost also occupies very large proportion in complete machine.
Present comparatively general rotary compressor, cylinder in its pump assembly and upper flange housing direct and compressor welds, and when pump assembly and housing welding, pump assembly can be out of shape because being heated, cause the assembly process process of compressor poor, thereby affect the service behaviour of compressor; And this kind structural design also can cause the oversize of pump assembly, and then causes complete machine to become large, the waste material.Simultaneously, the housing of pump assembly and compressor is welded, and goes out in compressor production or in using when unusual, can't dismantle pump assembly and keep in repair, and needs to change whole compressor, causes the Rework Technics of compressor poor.
The model utility content
In view of the above problems, the utility model provides a kind of fixed structure of pump assembly of rotary compressor.
In order to achieve the above object, the utility model has adopted following technological scheme:
A kind of fixed structure of pump assembly of rotary compressor, this pump assembly comprises upper flange, cylinder, dividing plate, lower flange, also comprises fixing frame, this upper flange and this fixing frame are fixed; Spring block, one end and this fixing frame are fixed, and the other end matches with the outer wall of this cylinder, and props up the sliding blade spring that arranges in this cylinder.
As optimal technical scheme of the present utility model: described fixing frame is circular, and this upper flange is fixed in the endoporus of this fixing frame.
As optimal technical scheme of the present utility model: the endoporus sidewall of described fixing frame is provided with the supporting portion, and this upper flange is arranged on this supporting portion, and by screw this upper flange and this supporting portion is fixed as one.
As optimal technical scheme of the present utility model: described fixing frame, its endoporus sidewall is provided with groove, and an end of this spring block is located in this groove, and should hold with this fixing frame by sunk screw and to fix.
As optimal technical scheme of the present utility model: the nut end of described sunk screw and the cylindrical sidewall of fixing frame are tangent.
As optimal technical scheme of the present utility model: the outer side surface of described spring block is cambered surface, and the radian of this cambered surface is consistent with the radian of this fixing frame cylindrical sidewall.
Compared with prior art, the utlity model has following advantage:
1, the housing of compressor directly and the fixing frame welding assembly, need not with the pump assembly effect, reduce thermal distortion to the impact of pump assembly; Simultaneously, the endoporus of fixing frame cooperates with the cylindrical of flange, can effectively guarantee coaxality between the two.
2, compressor then only need be backed out screw when unusually scrapping, and pulls down fixing frame, and just can be complete pull down reclaimed pump assembly and re-used the scrappage of reduction pump assembly.
3, upper flange sinks in the fixing frame, can reduce the whole height of compressor, reduces the used correlated parts material of pump assembly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view that upper flange cooperates with fixing frame in the utility model.
Fig. 3 is the structural representation of fixing frame in the utility model.
Fig. 4 is the structural representation of the utility model medi-spring block.
Embodiment
See also Fig. 1 to Fig. 4, the utility model is the fixed structure of the pump assembly of rotary compressor, and this pump assembly mainly comprises upper flange 101, cylinder 102, dividing plate (not shown), lower flange (not shown).Wherein, upper flange 101 is fixed as one with fixing frame 103.
This fixing frame 103 is circular, its endoporus sidewall is provided with the supporting portion 104 of two horizontal expansions, supporting portion 104 is provided with screw hole, and this upper flange 101 is arranged on this supporting portion 104, and by screw 110 this upper flange 101 is fixed as one with this supporting portion 104.This kind structure is easy to assembly, reliable, and the endoporus of fixing frame 103 cooperates with the cylindrical of upper flange 101, can effectively guarantee coaxality between the two; Simultaneously, upper flange 101 sinks in the fixing frame 103, can reduce the whole height of compressor, reduces pump housing size and used correlated parts material.
Endoporus sidewall at this fixing frame 103 is provided with groove 108, and an end 106 of spring block 105 is located in this groove 108, and by sunk screw 109 that the end 106 of this spring block 105 is fixing with fixing frame 103.The nut end of this sunk screw 109 and the cylindrical sidewall of fixing frame 103 are tangent; After the assembling, the nut end of sunk screw 109 is just tactile mutually with the housing (not shown) inwall of compressor, so just limited moving axially of sunk screw 109, even can prevent effectively also that in the very strong situation of vibrations sunk screw 109 is loosening, avoid causing that because of vibrations spring block 105 is loosening.
The other end 107 of this spring block 105, its outer side surface is cambered surface, the radian of this cambered surface is consistent with the radian of these fixing frame 103 cylindrical sidewalls, this end madial wall matches with the outer wall of this cylinder 102, and prop up the sliding blade spring (not shown) of these cylinder 102 interior settings, be used for the degrees of freedom of this sliding blade spring tail end of constraint.
Adopt this kind structure, pump assembly and fixing frame 103 are fixing; During assembling, the housing (not shown) of compressor just can be directly and fixing frame 103 welding, need not with the pump assembly effect, reduce thermal distortion to the impact of pump assembly; Simultaneously,, then only need back out the pump assembly of pulling down that screw 110 just can be complete and re-use the scrappage of reduction pump assembly when unusually scrapping at compressor.
The above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
