Abstract
The utility model relates to an air-conditioning compressor cylinder connection structure, which comprises a housing and a cylinder, and many fixing ribs protrude from the cylinder outer wall and mould integrated with the cylinder outer wall and are matched with the housing inner wall; the top side surface of the fixing rib is provided with a weld part matched with the housing contact side, and a weld part has a welding groove opened at the top side surface of the fixing rib and welding apertures opened on the housing.
Description
[technical field]
The utility model relates to technical field of refrigeration compressors, relates in particular to a kind of air condition compressor cylinder linkage structure.
[background technique]
The Type of Welding of the rotation roller type air condition compressor pump housing and housing generally is divided into cylinder and housing welding, flange and these two-part of housing welding, is called for short welding cylinder and weldering flange arrangement.Wherein the fit system of cylinder and housing is generally cylinder cylindrical annulus and housing carries out Spielpassung in the welding cylinder structure, and fixes through the mode of welding, and solder joint is arranged on the annulus side, can adopt Pierced structure between annulus part and the cylinder operation part.Because the rotary compressor cylinder adopts foundry goods more; Pierced structure manufacturability when casting is relatively poor, has casting defect easily, causes the cylinder rigidity not enough; Can not well fix the whole pump housing after housing and the pump housing welding; This will influence the coaxial degree of compressor rotor, and then compressor performance is impacted, and the probability that electromagnetic noise occurs also can increase; Certainly also can adopt entity structure between annulus part and the cylinder operation part, though entity structure can guarantee this rigidity, materials are many, and cost is high, uses less.
[model utility content]
The utility model provides a kind of simple in structure, welding and processing technology convenient, and versatility is high, avoids casting defect, increases the pump housing and housing welding rigidity, the air condition compressor cylinder linkage structure of raising compressor anufacturability.
For reaching above purpose, adopt following technological scheme:
A kind of air condition compressor cylinder linkage structure comprises housing and cylinder, and said cylinder outer wall stretches out a plurality of and fixing ribs that with inner walls match one-body molded with it; The side, top of said fixing ribs is provided with the weld part that matches with the housing contacting side.
Said weld part is that the welding groove and the correspondence that are opened in side, fixing ribs top are opened in the welding hole on the housing.
The beneficial effect of the utility model:
The utility model is through stretching out a plurality of and fixing ribs that with inner walls match one-body molded with it at cylinder outer wall; Side, top in fixing ribs is provided with the weld part that matches with the housing contacting side; Weld part is that the welding groove and the correspondence that are opened in side, fixing ribs top are opened in the welding hole on the housing, and the Pierced structure between existing cylinder cylindrical of this linkage structure cancellation and the cylinder operation part is on the basis that reduces the existing structure cost; Avoid casting defect; Increase the pump housing and housing welding rigidity, reducing the cylinder cost, guaranteeing to improve the compressor anufacturability again on the basis of welding rigidity.
[description of drawings]
Fig. 1 is the structural drawing of the utility model cylinder;
Fig. 2 is the E-E sectional view of Fig. 1;
Fig. 3 is the linkage structure cross-sectional view of the utility model cylinder and housing.
[embodiment]
To combine accompanying drawing that the utility model is further specified below:
To shown in Figure 3, a kind of air condition compressor cylinder linkage structure comprises housing 1 and cylinder 2 like Fig. 1, cylinder outer wall stretch out three with its one casting and the fixing ribs (20,21,22) that matches with housing 1 inwall; The side, top of said fixing ribs (20,21,22) is provided with the weld part (3,4,5) that matches with housing 1 contacting side, weld part (3,4,5) for the welding groove (200,210,220) that is opened in all fixing ribs (20,21,22) side, top and corresponding be opened in welding hole on the housing 1 (200 ', 210 ', 220 ').
When assembling connects; Through weld part (3,4,5) go up fixing ribs (20,21,22) side, top welding groove (200,210,220) and the welding hole on the housing 1 (200 ', 210 ', 220 '); Utilize welding gun directly that housing 1 and cylinder 2 is integrally welded, this linkage structure is compared with the Pierced structure between cylinder cylindrical and the cylinder operation part in the past, on the basis that reduces construction cost; Avoid casting defect; Increase the pump housing and housing welding rigidity, reducing the cylinder cost, guaranteeing to improve the compressor anufacturability again on the basis of welding rigidity.
The above embodiment; It is the preferred embodiments of the utility model; Be not to limit the utility model practical range,, all should be included in the utility model patent claim so all equivalences of doing according to the described structure of the utility model claim, characteristic and principle change or modify.
Claims (2)
1. an air condition compressor cylinder linkage structure comprises housing and cylinder, it is characterized in that,
Said cylinder outer wall stretches out a plurality of and fixing ribs that with inner walls match one-body molded with it;
The side, top of said fixing ribs is provided with the weld part that matches with the housing contacting side.
2. a kind of air condition compressor cylinder linkage structure according to claim 1 is characterized in that, said weld part is that the welding groove and the correspondence that are opened in side, fixing ribs top are opened in the welding hole on the housing.
