Abstract
The utility model discloses a compressor shell, relating to the technical field of compressor manufacture. The compressor shell comprises a cylindrical shell, wherein the cylinder wall of the shell is provided with a plurality of installation feet which are perpendicular towards the axial line of the shell, and the connecting position of each installation foot and the shell is provided with a groove. Compared with the prior art, the compressor shell disclosed by the utility model can overcome the defects of looseness, air hole and the like generated in the connecting position of each installation foot and the shell when the traditional compressor shell is cast so as to improve the qualified rate of products, is favorable for chip removal during hole drilling and tapping, increases the processing speed and reduces the production cost.
Description
Technical field
The utility model relates to Compressor Manufacturing technical field, especially a kind of casing for scroll compressor.
Background technique
Compressor case is one of basic components important in scroll compressor, and it plays supports and is containing various parts, and scroll compressor is connected with connecting base by the installation leg on compressor case.Have a kind of scroll compressor casing, this compressor case has a columnar housing, on the barrel of housing, be provided with a plurality of with towards the vertical installation foot of housing axis, in described installation leg bottom, be provided with tapped hole.In use there is following deficiency in the compressor case that is provided with this installation foot structure: because the blank of this compressor case adopts aluminum alloy by precision casting, installation foot is that to be distributed in the bump materials of compressor case barrel many, during cast, because installation foot and the alloy aluminum liquid of housing joint retain, how each position rate of cooling are different, the defects such as the inner easily formation in this joint is loose, pore; When completing boring to installation foot, tapping processing and check, can find that many tapped holes that foot is installed are communicated with the inner chamber of compressor case by loose hole, steam vent, during installation, often there is herein oil leakage phenomenon, not only cause the accepted product percentage of compressor case low, cost of production increases, and also directly affects the manufacturing schedule of compressor case.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of compressor case, when it can eliminate the casting of existing compressor case in installation foot and housing joint the defect such as inner loose, the pore producing, raising product qualified rate, reduce production costs.
The technological scheme that the utility model technical solution problem adopts is: this compressor case includes columnar housing, on the barrel of described housing, be provided with a plurality ofly towards the installation foot vertical with housing axis, described in each, the joint of installation foot and described housing is provided with a groove.
In above-mentioned compressor casing technological scheme, technological scheme can also be more specifically: the bottom surface of described groove is the arc shaped surface corresponding with described housing outer surface, and the described bottom surface of described groove to the thickness between described institute shell inner surface equates with the thickness of described housing barrel.
Owing to having adopted technique scheme, the utility model compared with prior art, the beneficial effect having is: 1, because the joint at each installation foot and housing is provided with groove, and groove floor is the arc shaped surface corresponding with housing outer surface, thickness between the bottom surface of groove to institute shell inner surface equates with the thickness of housing barrel, during cast, because this joint thickness equates with the thickness of housing barrel, do not have too much alloy aluminum liquid to retain, when cooling, the contraction at each position is consistent, can be in the joint inner phenomenon that forms the defects such as loose, pore; Improve product qualified rate, reduce production costs; 2,, because the joint at each installation foot and housing is provided with groove, during cast, reduced the corresponding cost of material that reduced of consumption of alloy aluminum liquid; 3, in the joint of each installation foot and housing, be provided with groove, the tapped hole on installation foot is through hole, is beneficial to the chip removal of boring, tapping, improves processing speed, reduces production costs.

Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is that the K of Fig. 1 is to view.
Fig. 3 is the sectional view at the D-D place of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Compressor case as depicted in figs. 1 and 2 includes columnar housing, this enforcement row example is provided with four towards the installation foot vertical with housing axis 1 on the barrel of housing, in each installation foot 1 and the joint of housing, be provided with a groove 2, the bottom surface 2-1 of groove 2 is the arc shaped surface corresponding with housing outer surface, and the bottom surface 2-1 of groove 2 equates with the thickness of housing barrel to the thickness between shell inner surface.Owing to being provided with groove 2 in each installation foot 1 and the joint of housing, and the bottom surface 2-1 of groove is the arc shaped surface corresponding with housing outer surface, the bottom surface 2-1 of groove 2 equates with the thickness of housing barrel to the thickness between institute's shell inner surface, during cast, because the thickness of this joint housing equates with the thickness of housing barrel, do not have too much alloy aluminum liquid to retain, when cooling the contraction at each position consistent, can be in the joint inner phenomenon that forms the defects such as loose, pore.
Claims (2)
