Abstract
The invention discloses a machine case of a compressor, and relates to the technical field of compressor manufacturing. The machine case of the compressor comprises a cylindrical shell body, multiple mounting feet with the facing directions perpendicular to the axis of the shell body are arranged on the barrel wall of the shell body, and a groove is formed in the connecting position of each mounting foot and the shell body. Compared with the prior art, the machine case of the compressor can eliminate the defects of loosening and air holes occurring to the interior of the connecting positions of the mounting feet and the shell body in the casting process of the machine case of an existing compressor, improves the product qualified rate, meanwhile is beneficial for chip removal in the process of drilling holes and tapping threads, improves machining speed and lowers production cost.
Description
Technical field
The present invention relates to the 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.A kind of scroll compressor casing is arranged, and this compressor case has a columnar housing, is provided with a plurality of with vertical towards housing axis installation foot on the barrel of housing, in described installation leg bottom, is 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 checked, can find that many tapped holes that foot is installed are communicated with the inner chamber of compressor case by loose hole, steam vent, oil leakage phenomenon often appears during installation herein, 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.
Summary of the invention
Technical problem to be solved by this invention 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 produced, the raising product qualified rate, reduce production costs.
The technological scheme that technical solution problem of the present invention adopts is: this compressor case includes columnar housing, be provided with a plurality ofly towards the installation foot vertical with the housing axis on the barrel of described housing, be provided with a groove in the joint of each described installation foot and described housing.
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 present invention compared with prior art, the beneficial effect had 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, be provided with groove in the joint of each installation foot and housing, the tapped hole on installation foot is through hole, is beneficial to the chip removal of boring, tapping, improves processing speed, reduces production costs.
The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
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 invention will be further described:
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 the housing axis 1 on the barrel of housing, be provided with a groove 2 in each installation foot 1 and the joint of housing, 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 in each installation foot 1 and the joint of housing, being provided with groove 2, 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)
1. a compressor case, include columnar housing, on the barrel of described housing, is provided with a plurality ofly towards the installation foot vertical with the housing axis (1), it is characterized in that: be provided with a groove (2) in the joint of each described installation foot and described housing.
2. compressor case according to claim 1, it is characterized in that: the bottom surface (2-1) of described groove (2) is the arc shaped surface corresponding with described housing outer surface, and the bottom surface (2-1) of described groove (2) to the thickness between described institute shell inner surface equates with the thickness of described housing barrel.
