Another object of the present utility model is also to provide a kind of compressor with above-mentioned compressor shell.
For solving the problems of the technologies described above, the compressor case that the utility model provides comprises housing and is arranged at the upper cover and the lower cover that is arranged on lower housing portion on housing top, and the contact position of described upper cover and described housing and described lower cover and described housing is for convenience of shirt rim or the butt joint edge of electric resistance welding.
Preferably, the contact position of described upper cover and described housing and described lower cover and described housing is all for convenience of the shirt rim of electric resistance welding.
Preferably, the contact position of described upper cover and described housing and described lower cover and described housing is all for convenience of the butt joint edge of electric resistance welding.
Preferably, a position butt joint edge for electric resistance welding for convenience in the contact position of the contact position of described upper cover and described housing and described lower cover and described housing, another one position is for convenience of the shirt rim of electric resistance welding.
Preferably, described upper cover, lower cover and described housing are sphere cast iron materials and make.
Compressor provided by the utility model comprises compressor case, and described compressor case is disclosed compressor case in as above any one.
By finding out in above technological scheme, compressor case provided by the utility model comprises housing and is arranged on the upper cover on housing top and is arranged on the lower cover of lower housing portion, and the contact position of upper cover and housing and lower cover and housing is for convenience of shirt rim or the butt joint edge of electric resistance welding.
Due to contact position shirt rim or the butt joint edge of electric resistance welding for convenience of upper cover and housing and lower cover and housing, in the process of therefore producing at compressor housing, upper cover and housing and lower cover and housing all can weld by resistance welding, than the mode of current electric arc welding, electric resistance welding can not need welding wire, welding rods etc. are filled metal, only need to utilize the pressure of electrode and electric discharge to complete welding, and the heating time of resistance welding is short, heat is concentrated, thereby heat-affected zone is little, deformation and stress is also little, as can be seen here, adopt electric resistance welding not only can effectively reduce the injury to human body in compressor case production process, but also can effectively improve the welding quality between upper cover and housing and lower cover and the housing of compressor case.
Compressor disclosed in the utility model is owing to having above-mentioned compressor shell, thereby this compressor has all advantages of above-mentioned compressor shell concurrently, herein this no longer repeated.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of compressor case in prior art;
The cross-sectional schematic of the compressor case that Fig. 2 provides for a kind of embodiment of the utility model;
The cross-sectional schematic of the compressor case that Fig. 3 provides for another embodiment of the utility model.
Embodiment
One of core of the present utility model is to provide a kind of compressor case, so that can either reduce the injury to human body in compressor case production process, can effectively improve again the welding quality between upper cover and housing and lower cover and the housing of compressor case.
Another core of the present utility model is to provide a kind of compressor with above-mentioned compressor shell.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The compressor case providing in the utility model embodiment comprises housing 1 and is arranged on the upper cover 2 on housing 1 top and is arranged on the lower cover 3 of housing 1 bottom, wherein upper cover 2 is all connected by the mode of welding with housing 1 with housing 1 and lower cover 3, than prior art, the core improvement of the compressor case providing in the present embodiment is, the contact position of upper cover 2 and housing 1 and lower cover 3 and housing 1 is all for convenience of shirt rim or the butt joint edge of electric resistance welding.
Due to upper cover 2 and contact position shirt rim or the butt joint edge of electric resistance welding for convenience of housing 1 and lower cover 3 and housing 1, in the process of therefore producing at compressor housing, upper cover 2 all can weld by resistance welding with housing 1 with housing 1 and lower cover 3, than the mode of current electric arc welding, electric resistance welding can not need welding wire, welding rods etc. are filled metal, only need to utilize the pressure of electrode and electric discharge to complete welding, and the heating time of resistance welding is short, heat is concentrated, thereby heat-affected zone is little, deformation and stress is also little, as can be seen here, adopt electric resistance welding not only can effectively reduce the injury to human body in compressor case production process, but also can effectively improve the welding quality between upper cover 2 and housing 1 and lower cover 3 and the housing 1 of compressor case.
As shown in Figure 2, in the compressor case providing in the present embodiment, the contact position of upper cover 2 and housing 1 and lower cover 3 and housing 1 is all for convenience of the shirt rim of electric resistance welding, concrete, the top and bottom of housing 1 are respectively arranged with to housing 1 outside turnover upper end flanging and the lower end flanging vertical with the sidewall of housing 1, the bottom of upper cover 2 embeds housing 1 inside, and be provided with for being overlapped on the upper cover convex edge on the flanging of upper end near the position of upper cover 2 bottoms on the sidewall of upper cover 2, described upper cover convex edge is overlapped on the flanging of described upper end, and form with described upper end flanging the skirt border structure that is applicable to electric resistance welding, the top of described lower cover 3 embeds housing 1 inside, and on the sidewall of lower cover 3 near the position of lower caping 3 ends be provided with for the lower cover convex edge of lower end flanging overlap joint, described lower cover convex edge is overlapped on the flanging of lower end and with lower end flanging and forms the skirt border structure that is applicable to electric resistance welding.
Please refer to Fig. 3, in the compressor case providing in the present embodiment, the contact position of upper cover 2 and housing 1 and lower cover 3 and housing 1 is all for convenience of the butt joint edge of electric resistance welding, concrete, the bottom diameter of upper cover 2 and the equal diameters of housing 1, just dock with the top of housing 1 upper cover 2 bottoms, forms the butt joint edge that facilitates electric resistance welding; The top of lower cover 3 also equates with the diameter of housing 1, and lower cover 3 tops are just docked with the bottom of housing 1 and formed the butt joint edge that facilitates electric resistance welding.
The accommodation that those skilled in the art easily expect is, any one position in the contact position of the contact position of upper cover 2 and housing 1 and lower cover 3 and housing 1 is set to facilitate the butt joint edge of electric resistance welding, and another position is set to facilitate the shirt rim of electric resistance welding.
